, Description:FIELD OF INVENTION
[0001] The present disclosure relates to field of remote monitoring and control systems and in particular to a tobacco barn monitoring and control system.

BACKGROUND
[0002] The background description can include information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Tobacco curing is an artificial process that creates conducive conditions for tobacco leaf to physiologically ripen. Drying of tobacco leaves is generally referred to as curing by tobacco cultivators. In order to consume tobacco leaves, it is necessary to cure them before consumption. Tobacco curing essentially involves removal of moisture from tobacco leaves without affecting its potential quality, color, flavor, texture and aroma. Color of leaf achieved by curing indicates that certain changes have taken place and is used as an index of leaf quality. Proper curing, hence, is a very significant factor in deciding market value of leaf.
[0004] The objectives of curing are to maintain life in leaf until biological processes are completed and can include a yellowing phase during which starch in leaf is converted to sugar, a leaf drying phase in which all bio chemical activities are stopped by removal of moisture in leaf and finally a preservation phase during which leaf is preserved by drying its stem.
[0005] Tobacco curing processes can be categorized as Air-cured, Flue-cured and Sun- cured. Air-curing of tobacco leaves is carried out in well ventilated barns wherein tobacco is hung for drying over a period of four to eight weeks. Air-cured tobacco produces a tobacco that is low in sugar content and high in nicotine content and gives a light, smooth, semi-sweet flavor to tobacco smoke.
[0006] Another process for curing tobacco leaves is Sun-curing in which tobacco is placed uncovered in sun and is made to dry out naturally over a period of time. Sun-cured tobacco is low in nicotine and sugar and is popular for cigarettes.
[0007] Another very popular method of curing tobacco is flue-curing. Flue-curing of tobacco is generally carried out in brick and mortar structures called barns, using a suitable fuel like wood to supply heat for removal of moisture from tobacco leaves. A plurality of flue pipes run across a barn and these flue pipes are connected to externally fed furnaces. Flue-curing involves stringing or hanging tobacco on to tobacco sticks that are hung from horizontal poles known as tier poles in tobacco curing kilns/barns. Tobacco thus hung is exposed to heat from flue pipes running throughout a barn to heat-cure it without exposing it to smoke by slowly raising temperature in the barn during the curing process that lasts for 6-7 days. This method produces tobacco that is high in sugar and has medium to high levels of nicotine.
[0008] Flue-curing tobacco has two objectives: (a) to provide temperature and humidity conditions that will encourage certain desirable chemical and biological changes to take place, and (b) to preserve leaf by timely drying to retain quality. There are typically three stages to flue-curing, the start and end of all such stages making up a curing cycle. Coloring is first stage in which color of tobacco leaves is fixed by chemical and enzymatic changes produced by heat applied to tobacco leaves. This process is conducted at operational temperatures of 30 – 40 ?C at a relative humidity of about 85 %. Lamina drying is second stage in which moisture is driven from tobacco leaves at operational temperatures of 40 – 50 ?C. Midrib drying is third stage in which mid-rib or stem of leaf is dried. During this stage, operational temperatures are 65 – 70 ?C, with diminishing humidity. Curing period for each stage varies with type and condition of tobacco leaves on plants, efficiency of curing barn used and local (ambient) conditions.
[0009] A variety of curing regimes exist that determine various process parameter values for curing tobacco such as temperature, humidity and time for each stage of a curing cycle. Selection of an appropriate curing regime is based on weather conditions, loading capacity of a barn and experience of barn supervisor/operator. Each barn by itself can be unique and so experience of its supervisor / operator plays a significant role in regime selection. Further, as can be appreciated, temperature and humidity requirements of a curing stage are highly weather dependent.
[0010] Flue-curing tobacco is a complex procedure because of the differences in types of tobacco like body, stalk position, moisture content, curing facilities, and weather conditions as well because each barn is different. Hence, it is difficult to use a set curing regime.
[0011] As elaborated above, flue-curing of tobacco involves different stages of curing with each stage having specified thresholds/ranges of temperature and humidity. Temperature and humidity levels play an important role in ensuring quality output of cured tobacco. A too high temperature may lead to burning of tobacco and a too low temperature may lead to improper curing thus affecting quality as well as quantity (yield) of cured tobacco. Although each stage is divided into roughly equal intervals, actual time required may vary for each stage. Curing regime is a general guide and actual regime followed may deviate due to factors such as tobacco ripeness and maturity, weather, airflow and others.
[0012] Typically, to have best quality tobacco leaves for further processing; leaves should have moisture content between 12-16%, so an ambient relative humidity of 60 to 68% is required to maintain equilibrium. During a curing process, maintaining proper relative humidity and temperature is very important. In case relative humidity is not maintained properly, tobacco leaves will lose moisture and weight causing poor quality. Similarly, maintaining improper temperature during curing process will negatively affect tobacco leaves and will reduce quality of tobacco in addition to causing post-production fermentation.
[0013] Tobacco is stored between all stages of processing. If tobacco is not stored at correct temperature and humidity, quality of tobacco won’t meet consumer requirements. If tobacco becomes heated, it may dry out and aromatic substances contained in it may be volatized. In this case, the tobacco may acquire hay like, bitter, sharp flavor. It may also become hard and brittle, meaning that leaves break under a slightest mechanical stress and eventually end up as powder. Therefore, it is very important to monitor and control temperature and relative humidity during curing, storage and transport of tobacco.
[0014] Further, tobacco leaves are highly hygroscopic. If relative humidity is excessive, tobacco absorbs so much water vapor that it becomes a nutrient medium for molds. Mold, mustiness, mildew stains and a musty odor reduces quality of tobacco. Depending on mold, white, grey, green or black spots are visible on tobacco leaves. In case of excessive heat and humidity, fermentation process may start up again. In which case, temperature in storage may rise by up to 2°C per day. It is highly recommended to monitor temperature so that adjustments can be made in order to stop fermentation process if required.
[0015] Due to complexities elaborated above, tobacco curing has been considered an art for many years and has been handed over to current generation of farmers as a legacy from their fathers and grandfathers for turning ripe harvested tobacco leaves to high-quality yellow gold cured leaves with good flavor and aroma desired by cigarette manufacturers. A limitation of this legacy is that currently farmers mostly use their experience and random guesswork to predict/ guess a barn’s temperature and humidity, using methods such as touching the barn walls or putting their hand inside the barn. This leads to inaccurate results that may damage tobacco being cured. Some farmers, in rare cases, also use a dry and wet bulb thermometer to monitor temperature. However, the same is cumbersome to use and it is not possible to enter a barn in third and fourth stage of tobacco curing due to high temperatures inside barn and so its use is very restricted. Consequently, existing systems lack accuracy in measuring and controlling process parameters of temperature and humidity, leading to cured tobacco of poor quality besides inefficient barn operation such as high fuel consumption.
[0016] Further, present systems require a person to be continuously present (such person generally termed as a farmer or a barn driver) to determine temperature and humidity inside the barn at frequent intervals and take corrective measures as required. This leads to high operational costs.
[0017] Further, current barns for flue-curing do not detect leakages in their flue duct systems. Consequently, flue gas may get contaminated with tobacco leaves leading to generation of benzopyrene that may contaminate further tobacco leaves which is not desired.
[0018] Current curing systems also do not have provisions for storing historical data of various parameters such as temperature, humidity and leakages, and actions taken at the time that can be used for taking similar actions in future similar conditions so as to improve overall the curing process.
[0019] Hence there is a need in the art wherein barn parameters can be continuously monitored and timely corrective actions taken to improve tobacco quality and lower the barn’s operational cost such as fuel and manpower, besides enabling access to historical data for taking future decisions on an informed basis.

[0097] In an aspect, proposed system can be configured in a computing device or across a plurality of computing devices operatively connected with each other, wherein the computing devices can be any of a computer, a laptop, a smartphone, a server, a cloud, a central computing device, an Internet enabled mobile device and the like. The proposed system can also be configured in the form of a mobile application with a client side that can reside in mobile devices of a local barn driver and a remote supervisor and receive notifications and a server side that can receive instructions from the barn driver / remote supervisor using their mobile devices, as elaborated hereunder..
[0098] In an aspect, the proposed system (system 102) can receive signals from a plurality of sensors 106 that can be configured inside a plurality of barns close to each other(shown as 104-1, 104-2, 104-4). Such sensors can determine various process parameters involved in tobacco curing viz temperature, humidity, smoke values and corresponding sensors’ status ( OK/not OK, for example), or any combination of these inside a barn. In an exemplary embodiment, 106-1 can be a temperature sensor for barn 104-1, 106-2 can be a humidity sensor for barn 104-1 and 106-3 can be a smoke sensor for barn 104-1. In a similar fashion, sensors can be configured inside other barns. In an aspect, a sensor can detect both temperature and humidity together.
[0099] In another aspect, system 102 can generate alarm signals when at least one process parameter goes beyond its threshold value, wherein the threshold value is determined based on tobacco curing stage. Such alarm signals can trigger various corresponding local audio/visual alarms such as bells, buzzers, LEDs etc. to alert the barn driver if he is locally present. In an exemplary embodiment, as illustrated in FIG. 1 such local alarms can be temperature alarm 108-1, humidity alarm 108-2 and smoke alarm 108-3 that can receive alarm signals pertaining to barn 104-1. In a similar fashion, various alarms can be configured for other barns too. In an exemplary embodiment, a single alarm device can be configured to receive alarm signals for various process parameters and trigger a common alert accordingly wherein the specific process parameter causing the alert can be displayed on a display, displays etc. accordingly.
[00100] It can be appreciated that the pre-determined threshold values can be ranges instead. For example, temperature range for a stage of curing can be 30-45 degrees centigrade. System 102 can generate an alarm signal when barn temperature falls below 30 degrees centigrade and also when barn temperature rises above 45 degrees centigrade. In an exemplary embodiment, 85°F – 105°F can be set as temperature range for yellowing stage of curing.
[00101] In another aspect, proposed system can enable a barn driver if he is locally present (such a barn driver termed as barn driver 110) to take local action to remove the alarm conditions.
[00102] In yet another aspect, in case local action is not taken within a pre-defined time, absence of such action can enable proposed system to trigger notification(s) to the Internet enabled devices of the barn driver 110 and his superior (interchangeably termed as remote supervisor 116). Any of them then can give appropriate instruction to the proposed system using their Internet enabled device/smart mobile device and proposed system can act to remove alarm conditions thereafter.
[00103] In yet another aspect, the instruction can be communicated to the local barn driver if the instruction is received from the remote supervisor, and the instruction can be communicated to the remote supervisor if the instruction is received from the local barn driver. This can avoid duplication of execution of instructions.
[00104] In an aspect a remote supervisor can control a plurality of barns while a barn driver can be locally present near a barn to take local actions as required.
[00105] In exemplary embodiment illustrated, upon an alarm signal being generated, system proposed can wait for a pre-defined time for barn driver 110 to take local action. In case barn driver 110 takes local action, (that can include instruction given locally to system) communication regarding the same can be sent to remote supervisor 116 for his information. However, in case barn driver 110 does not take local action, absence of such communication/instruction can enable the system to trigger notification(s) to the Internet enabled devices of the barn driver 110 and that of remote supervisor 116. Any of them then can give appropriate instruction to the proposed system using their Internet enabled device/smart mobile device and proposed system can act to remove alarm conditions thereafter. For example, remote supervisor 116 can receive such notification on his internet enabled device 114 and can give instruction to proposed system using the same device to enable the system to take appropriate corrective action(s) accordingly to remove conditions causing the alarm. Upon receipt of instruction, proposed system can communicate the instruction received from the remote supervisor 116 to the barn driver110 so that there is no duplication of instruction.
[00106] To illustrate, temperature in the barn can cross its threshold value. An alarm signal can be accordingly generated. The alarm signal can trigger a local alarm such as a bell. If a barn driver is locally present he can take local action (such as switching off a burner or removing some wood from the barn’s furnace) to bring the temperature below its threshold value.
[00107] In case the barn temperature does not fall within a pre-defined time (thereby indicating no local action), proposed system can trigger a notification to the Internet enabled devices of the barn driver and his supervisor. Any of them then can give an instruction to the proposed system using their Internet enabled device and proposed system can act to remove alarm conditions thereafter.
[00108] In an aspect, local alarms generated can have snooze buttons to enable a local user /farmer/barn driver to temporarily silence them.
[00109] In yet another aspect, system 102 can transmit process parameter values like temperature, humidity and smoke values in real time on a continuous basis from a barn to a cloud server 112 that can be configured to store these parameter values. System 102 can perform analytics on such data and offer actionable insights for barn operation to enhance cured tobacco quality and yield.
[00110] In an aspect, system 102 can change a stage of curing of tobacco in a barn either upon manual operation by a barn driver or automatically, and adjust threshold values of the process parameters accordingly. Buttons can be provided in system proposed to enable manual change by the barn driver. The buttons can have backlit LEDs to indicate current curing stage as well as blink when their stage is approaching to serve as a reminder to the barn driver.
[00111] In another aspect, system 102 can monitor time of operation of each stage and can automatically switch between different stages. In yet another aspect, system 102 can instead notify barn driver about a stage change requirement by physical alert such as LEDs as elaborated above and/or digital notification alerts.
[00112] In an exemplary embodiment, some aspects of proposed system102 can be configured to work as a web application that can be accessed by any Internet enabled device such as a PC or a smartphone to enable appropriate functions.
[00113] In another aspect, proposed system can send SMS alerts/notifications pertaining to alarms to pre-registered mobile numbers. The notifications can include sensor data causing the alarm as well as suggestions regarding actions to be taken by the barn driver or remote supervisor. In another aspect, proposed system can also send notifications over E-mail, automated phone calls or use push notifications to any Internet enabled device such as a PC, a mobile phone and the like. In this fashion, a remote supervisor can monitor and control tobacco flue curing process.
[00114] In an aspect, system 102 can include a Liquid Crystal Display (LCD) that displays current process parameter values such as temperature and humidity values along with sensor status to a barn driver. A wake-up button can be provided for operating the LCD display and turning it off after a specified time and so save on power. In an exemplary embodiment, the LCD display can be of the 8 segments 4 digit type. In another exemplary embodiment, LCD display can also show smoke values in ppm in corresponding barn.
[00115] In an aspect, proposed system can categorize values for various process parameters collected for each curing cycle as well as any time in between.
[00116] In another aspect, system 102 can have means to switch between multiple curing regimes wherein a curing regime can be selected from any or a combination of ambient weather conditions, tobacco load, required quality of cured tobacco, yield required of cured tobacco, process parameters threshold values for each curing stage and duration of each curing stage. The threshold values can accordingly be determined.
[00117] In an exemplary embodiment, a barn driver or a remote supervisor can provide ambient weather conditions, load and quality desired to system 102 that can thereafter suggest one or a plurality of curing regimes to the barn driver/ remote supervisor to choose from. The barn driver/ remote supervisor can select one of these regimes based upon his experience as well as his knowledge of the specific barn. The curing regime can in turn determine a curing cycle and threshold values of various process parameters in each stage of the curing cycle.
[00118] In an aspect, system proposed can continue to use existing regime unless changed deliberately by barn driver/ remote supervisor.
[00119] In yet another aspect, system proposed can enable a regime to be changed in intermediate stage of the ongoing cycle as well. In this case, for example, the barn driver can define the time limit required to complete an ongoing stage of a cycle based on a present regime and select a new regime. System proposed can determine time, temp and humidity thresholds for all the upcoming stages based on the new regime selected.
[00120] In another exemplary embodiment, system proposed can be configured to receive ambient temperature and humidity inputs by means of appropriate sensors installed outside the barn and alert any or a combination of the barn driver and the remote supervisor for a possible / needed change in a regime.
[00121] In an aspect, system allows multiple barns close to each other to be connected to a single barn monitoring device that acts as a gateway for all connected barns, thereby reducing costs of monitoring multiple barns. In this fashion, proposed system can provide real time monitoring and control for a plurality of tobacco curing barns to a plurality of users.
[00122] In yet another aspect, system 102 can continuously transmit various process parameter values and other data as elaborated herein for analytics and insight purposes to a cloud server 112 from where proposed system can perform various analytics on it as elaborated herein to gain useful insights for barn operation.
[00123] FIG 2 illustrates various modules of proposed system 102, in accordance with embodiments of the present disclosure. The proposed system 102 can include a Sensor Signal Receipt Module 202, Alarm Module 204, Signal Transmission Module 206, Stage Control Module 208, Control Instruction Receipt and Execution Module 210, a Reset Module 212 and an Analytics Module 214.

Sensor Signal Receipt Module 202
[00124] In an aspect, proposed system 102can include a Sensor Signal Receipt Module 202 that communicates with a plurality of sensors 106-1,106-2,106-3to receive process parameter values such as temperature, humidity and smoke values in the barn being monitored and controlled. In an aspect, module 202 can receive such values from sensors 106 wirelessly or via wires that can withstand high temperature (shown as 616 in FIG. 6).
[00125] In another aspect, module 202 can store process parameter values received and can provide them to analytics module 214 as elaborated hereunder. Module 202 can also enable such storage at cloud server 112 (shown in FIG. 1).

Alarm Module 204
[00126] In yet another aspect, module 202 can pass process parameter values received to an Alarm Module 204 that can be configured to generate alarm signals if process parameter values go beyond their threshold values based upon the stage of curing process/ curing regime, as elaborated further.
[00127] In another aspect, alarm signals generated as above can be used to trigger local alarms such as local audio/visual alarms like bells, buzzers, LEDs etc. to alert the barn driver if he is locally present.
[00128] It can be appreciated that the threshold values can be ranges. For example, temperature range for a stage of curing can be 30-45 degrees centigrade. Module 204 can generate an alarm signal when barn temperature falls below 30 degrees centigrade and also when barn temperature rises above 45 degrees centigrade.
[00129] In another aspect, module 204 can use the alarm signals to immediately trigger local alarms (displayed as 108-1, 108-2 and 108-3 in FIG 1) for attention of and to enable barn driver to take local actions. In an exemplary embodiment, if barn temperature has exceeded its threshold value, barn driver110 can hear the local alarm and can quickly remove wood from the barn furnace in order that barn temperature comes back below its threshold value.
[00130] In an aspect, module 204 can enable a barn driver 110 to snooze/silence any local alarm by stopping corresponding alarm signal using appropriate buttons such as 614 (shown in FIG. 6).

Signal Transmission Module 206
[00131] In another aspect, proposed system 102 can include a Signal Transmission Module 206 to transmit real time process parameter values like temperature, humidity and smoke values as well as alarm signals generated by module 204, and notifications, as elaborated hereunder.
[00132] In an aspect module 206 can transmit in real time various process parameter values, alarm signals and notifications to a cloud server 112 for storage and further actions therein as elaborated hereunder.
[00133] In yet another aspect module 206 can receive from module 210 various instructions being generated by either barn driver110 or barn supervisor 116 and can in turn notify at least the party not generating the instructions about the instructions so that there is no duplication of execution of the instructions.
[00134] In yet another aspect, module 206 can wait for a pre-defined time for the barn driver 110 to take local action, and thereafter, in case barn driver110 takes no local action (as can also be determined by no receipt of instructions from him within the pre-defined time), use the alarm signals to in turn trigger notifications that it can send to internet enabled device of both the barn driver 110 and the corresponding remote supervisor 116. Module 206 can also determine no local action has been taken on an alarm signal if process parameter value for same has not started approaching its corresponding threshold value at end of the predetermined time.
[00135] In an aspect, notifications can contain process parameter values as well as their threshold values. In another aspect, notifications can also indicate corrective instructions expected from the recipient (local barn driver or remote supervisor, as elaborated hereunder)
[00136] In an aspect, module 206 can transmit various notifications to barn driver 110 or remote supervisor 116 using a GSM network. Notifications can be sent as SMS/ ringer/buzzer/ automated phone call to pre-registered mobile numbers. Module 206 can transmit notifications by sending appropriate E-mails and/or push notifications to an appropriately configured Internet enabled device (that can be of the barn driver and/or the supervisor) using the Internet.

Stage Control Module 208
[00137] In an aspect, proposed system 102 can include a Stage Control Module 208. Module 208 can set different threshold values of the process parameters according to stage of curing of tobacco as well as duration of that stage, and likewise for all stages of curing. Module 208 can set a stage based upon corresponding actions by barn driver 110. In an exemplary embodiment, a stage change button 610 can be provided in proposed system for the purpose.
[00138] In another aspect, module 208 can enable automatic stage change based upon time elapsed from start of curing. For the purpose module 208 can get time elapsed signals from an RTC (Real time clock) that can either be within system 102 or operatively connected with it. Module 208 can indicate various stages by buttons backlit by LEDs. In an aspect module 208 can indicate an upcoming stage by causing its corresponding button to blink, using the LED therein. The blinking button can remind the barn driver about an upcoming stage change. In an aspect, the button can be made to blink some time before a stage change is needed. For example, button of a stage can start blinking 10 minutes before end of the current stage, thereby serving as a reminder to the barn driver about an upcoming change.
[00139] In yet another aspect, module 208 can generate alarm signals for module 204 when actual time duration of a stage has expired. At that time, system proposed can produce local audio / visual alarms for local barn driver to note and act upon.
[00140] In yet another aspect, module 208 can pass on information regarding different threshold values at any time to alarm module 204 that can use such values to generate alarm signals as elaborated above.
[00141] In an exemplary embodiment, module 208 can set a coloring stage for duration of 4 hours, a lamina drying stage for 30 hours and a midrib drying stage for further 30 hours. It can be appreciated that within each stage there can be variations required in temperature / humidity in the barn. Module 208 can control process parameters accordingly.
[00142] It can also be appreciated that tobacco curing does not follow a single curing routine (regime) as both of its process parameters i.e. temperature and humidity, are weather and load dependent and affect the quality and output of cured tobacco. Process parameters and duration of each stage depend upon ambient weather conditions (like sunny, cloudy, rainy etc.) and quantity of tobacco leaves (that is, load) in a barn. System proposed can configure multiple curing regimes incorporating all these factors that can then be enabled using module 208.
[00143] In an exemplary embodiment, a barn driver or a remote supervisor can provide ambient weather conditions, load and quality desired to system proposed and module 208 can thereafter suggest one or a plurality of curing regimes to the barn driver/ remote supervisor to choose from. The barn driver/ remote supervisor can select one of these regimes. The curing regime can in turn determine a curing cycle and threshold values of various process parameters in each stage of the curing cycle.
[00144] In an aspect, system proposed can continue to use existing regime unless changed deliberately by barn driver/ remote supervisor.
[00145] In another exemplary embodiment, system proposed can be configured to receive ambient temperature and humidity inputs by means of appropriate sensors installed outside the barn and alert any or a combination of the barn driver and the remote supervisor for a possible / needed change in a regime.
[00146] In another aspect, system proposed can have buttons to enable manual selection of a curing regime according to parameters elaborated above that can in turn set the threshold values of various process parameters as elaborated above. In yet another aspect, the regimes can also be selected through mobile/web app of system proposed.
[00147] In yet another aspect, module 208 can pass information regarding each curing cycle such as curing regime selected, ambient weather conditions, barn load etc. to cloud server 112.

Instructions Receipt and Execution Module 210
[00148] In yet another aspect, proposed system 102 can include an Instruction Receipt and Execution Module 210 to receive instructions from barn driver110 or from remote supervisor 116 as appropriate for correcting conditions/ process parameter values generating the alarm signals/ notifications and further execute such instructions, as well as for other functions elaborated herein. Such instructions can also include instruction given locally by the local barn driver to system disclosed, when the local barn driver is taking a local action.
[00149] In an exemplary embodiment, in case of a smoke alarm, module 210 can receive instruction from a local barn driver and accordingly close the flue pipe valve that is leaking. In a similar fashion, in case of a temperature alert, module 210 can receive instructions from a remote supervisor and switch on/off the flue burners as required. These instructions can be given on Internet enabled devices of the barn driver or the remote supervisor.
[00150] In another aspect, module 210 can enable system disclosed to take various corrective actions automatically without any action by the barn driver or the remote supervisor. In such a situation, module 210 can get actual process parameter values from module 202 and threshold values of process parameters from module 204, can determine if the threshold limits have been crossed and if so, take appropriate corrective actions automatically to bring actual process parameters values within threshold values.
[00151] In yet another aspect, module 210 can receive instructions for silencing/resetting/snoozing an alarm and do accordingly.
[00152] In another aspect, module 210 can receive instructions for changing curing stage. Module 210 can instruct module 208 accordingly.
[00153] In an aspect, module 210 can transmit all instructions received to cloud server 112 for storage therein as well as further use by system disclosed, as elaborated herein.
[00154] In yet another aspect, module 210 can keep track of all local actions taken and transmit data regarding these to cloud server 112 for storage therein as well as further use by system disclosed, as elaborated herein.
[00155] In an aspect, module 210 can transmit an instruction to the local barn driver if the instruction is received from the remote supervisor, and transmit an instruction to the remote supervisor if the instruction is received from the local barn driver. In this way, duplication of execution of instructions can be avoided.

Reset Module 212
[00156] In an aspect, reset module 212 can segregate all process parameter values stored in cloud server 112 during a curing cycle from the other curing cycles by sending appropriate signals to cloud server 112 at start and end of the curing cycle. Such signals can be sent automatically by module 212 or upon receipt of appropriate instructions either by the local barn driver or the remote supervisor. In an exemplary embodiment, a reset button 614 can be provided on control panel of system disclosed that a local barn driver can use to signify start or end of a curing cycle to proposed system. In this fashion, proposed system can segregate process parameter values for each curing cycle to facilitate further analytics and evaluation using module 214.
[00157] In another aspect, module 212 can receive in real-time for a cycle, data regarding quality (that can be highest, lowest and average) and quantity of cured tobacco produced, actual and threshold process parameter values, alarm signals generated, notifications triggered, local actions taken and instructions received for that curing cycle from either the local barn driver or the remote supervisor. Module 212 can also receive information regarding quality and quantity desired that was initially set for the curing cycle. Module 212 can send all such information to cloud server 112 that can store it to facilitate further analytics and evaluation using module 214.
[00158] In an exemplary embodiment, module 212 can be configured within cloud server 112 itself and can receive signals to trigger its operation from reset button 614.
Analytics Module 214
[00159] In an aspect analytics module 214 can perform various analytics on process parameter values and other data stored in the cloud server 112. As elaborated above cloud server 112 can receive all process parameter values, alarm signals generated, notifications triggered, local actions taken and instructions received pertaining to a curing cycle from module 206 and module 212 , the curing regime selected for that cycle from module 208; and quality and quantity of cured tobacco required and quality and quantity of cured tobacco produced by that curing cycle from module 212
[00160] In yet another aspect, module 214 can present all data of a curing cycle (and likewise of a plurality of curing cycles) in a graphical format to any one so authorized (that can be the remote supervisor, for example) on a real-time basis or as a downloadable archive once the cycle is finished or at any time in-between. Alarm signals can also be displayed on such graphs when a process parameter value is outside the specified range at the time. For example, temperature threshold range required at a time can be 30 degrees centigrade to 45 degrees centigrade. If actual barn temperature falls to 28 degree centigrade, an alarm signal can be generated and also displayed graphically by an upwards arrow. Data regarding curing regime selected for that curing cycle as well as quality and quantity of cured tobacco finally generated as well as what was desired by that curing cycle can also be presented visually. In an exemplary embodiment, 85°F – 105°F can be set as temperature range for yellowing stage of curing.
[00161] In an aspect, Module 214 can display instructions received either from the barn driver or the remote supervisor so that both are aware of actions being taken by the other as well as its impact on curing process.
[00162] In this fashion, system proposed can enable an authorized user (that can be remote supervisor) to track, compare and analyze the data gathered from a barn (or from multiple barns under his control) over different time periods, seasons, curing cycles and regimes. Such analysis can provide actionable insights to improve the quality and quantity of cured tobacco by adjusting future curing regimes accordingly.
[00163] In an aspect, module 214 can present all such data in any vernacular language selected.
[00164] In an exemplary embodiment, sensors 106can be connected to the Sensor Signal Receipt Module 202using wire 616 that can withstand high temperatures ( for example, upto 125 degrees centigrade) or wirelessly or any combination of these. Wireless connections may be made using a Zigbee controller MeshConnect EM357 High Temp Mini-Module and may require a separate microcontroller & an internal battery.
[00165] In another exemplary embodiment, sensors can be placed at center of a corresponding barn to enable most accurate data collection.
[00166] In an aspect, alarms can be of different types such as, but not limited to, buzzer 604, backlit LEDs 612 or a combination of these.
[00167] FIG. 3 illustrates via a flow diagram, the method of working of proposed system, in accordance with an exemplary embodiment of the present disclosure.
[00168] In an aspect, the method can include, at step 302, receiving, at a computing device, at least one process parameter value from at least one barn sensor.
[00169] In another aspect, the method can include, at step 304, storing, at the computing device, the at least one process parameter value.
[00170] In an aspect, the method can include, at step 306, determining if the at least one process parameter value is beyond its threshold value.
[00171] In another aspect, if the at least one process parameter value is not beyond its threshold value, the method can include repeating steps 302 to 306.
[00172] In an aspect, if the at least one process parameter value is beyond its threshold value, the method can include, at step 308, generating, at the computing device, an alarm signal and triggering a local alarm for a local barn driver.
[00173] In another aspect , the method can include, at step 310, determining if a local action has been taken by the local barn driver to bring the at least one process parameter value within its threshold value within a pre-defined time period.
[00174] In another aspect, if the local action has been taken by the local barn driver to bring the at least one process parameter value within its threshold value within the pre-defined time period, the method can include, at step 312, stopping the alarm signal and communicating the local action to a remote supervisor,
[00175] In another aspect , if no local action has been taken by the local barn driver to bring the at least one process parameter value within its threshold value within the pre-defined time period, the method can include, at step 314, transmitting, at the computing device, a notification to the local barn driver and the remote supervisor.
[00176] In an aspect, the method can include, at step 316, enabling any of the local barn driver or the remote supervisor to generate an instruction to bring the at least one process parameter value within its threshold value upon receipt of the notification.
[00177] In another aspect, the method can include, at step 318, communicating the instruction to the local barn if the instruction is received from the remote supervisor, or communicating the instruction to the remote supervisor if the instruction is received from the local barn driver.
[00178] FIG. 4 illustrates via an example working of proposed system, in accordance with an exemplary embodiment of the present disclosure.
[00179] System 102 can generate an alarm signal in case a process parameter value exceeds its threshold value. As shown, the alarm signal can generate/trigger a local alarm 402 that can be acted upon by local barn driver 110 via local action 404 to bring the process parameter value within its threshold value.
[00180] System 102 can send communication regarding local action 404 to the remote supervisor 116 as illustrated by communication 406. Communication 406 can enable remote supervisor 116 not to give unnecessary instruction to system 102 as local action has already been taken by barn driver 110.
[00181] FIG. 5 illustrates via another example working of proposed system, in accordance with an exemplary embodiment of the present disclosure
[00182] As illustrated, System 102 can generate/trigger a local alarm 502 in case a process parameter value exceeds its threshold value. System 102 can wait for a pre-defined time for local action by the barn driver 110 and can determine no local action is taken by the barn driver within such time. Then system 102 can trigger notification 504 to remote supervisor 116 and barn driver 110. In exemplary embodiment shown, remote supervisor 116 can give instruction 506 to system 102 based upon which system 102 can take corrective actions.
[00183] System 102 can send communication regarding receipt of instruction 506 to the barn driver 110 as illustrated by communication 508. Communication 508 can enable local barn driver 110 not to give unnecessary instruction to system 102 as appropriate instruction has already been given by remote supervisor 516.
[00184] FIG. 6 shows an exemplary control panel of proposed system, in accordance with an exemplary embodiment of the present disclosure.
[00185] As illustrated, proposed system can include a variety of features to assist in performing various functions elaborated above. Proposed system 102can include an 8 segments 4-digit Liquid crystal display (LCD) 602 to show current process parameter values of temperature, humidity and smoke as well as corresponding sensor status at all times to a barn driver. In an aspect, LCD 602 can show current temperature. System 102 can receive such data from corresponding barn sensors, as elaborated above. LCD 602 can switch itself off after a preset time in order to save power and a wake button 608 can be provided to switch it on again, whenever a barn driver so requires.
[00186] In another aspect, proposed system can receive process parameter values from different sensors via wires that can withstand high temperature(shown as 616) and, in case a process parameter value crosses its threshold value can raise different kinds of alarms, for example Buzzer 604. A snooze button 606 can be provided to silence the alarm for (or after) a pre-determined period, if required. Alarms can also be in form of LED indicators.
[00187] In yet another aspect, proposed system can include a plurality of stage change buttons 610 using which a barn driver can manually change stage of curing of tobacco in the barn. Each button 610 can have a backlit LED 612 that can be lit when corresponding stage is operative. An LED 612 can automatically blink to remind the barn driver that time to change stage is approaching. Button 610 can have backlit LEDs 612.
[00188] In an aspect, module 202 can receive such data from sensors 106 wirelessly or via high temperature wires (shown as 616 in FIG. 6).
[00189] In an aspect, proposed System can include a reset button 614 that can be used to segregate one curing cycle process parameter values from that of others, as already elaborated above. Since there is a considerable time gap between two consecutive cycles in tobacco curing, such data segregation can be easily done.
[00190] In an aspect, multiple nearby barns 104 can be connected to a single system 102 as elaborated above that can act as a gateway for all. In an aspect, connecting multiple tobacco barns 104-1,104-2,104-3to a single Barn monitoring system 102can reduce barn monitoring costs as multiplicity of systems and barn driver as well as remote supervisor can be avoided.
[00191] Although the proposed system has been elaborated as above to include all the main modules, it is completely possible that actual implementations may include only a part of the proposed modules or a combination of those or a division of those into sub-modules in various combinations across multiple devices that can be operatively coupled with each other, including in the cloud. Further the modules can be configured in any sequence to achieve objectives elaborated.
