PRIORITY INFORMATION
[001] This patent application does not take priority from any application.
TECHNICAL FIELD
[002] The present subject matter described herein, in general, relates to the field of environmental monitoring. More specifically, a method and system for activating sensors to monitor environmental conditions in a geographical area.

BACKGROUND
[003] Soil condition plays a vital role in agriculture. Soil and environmental parameters such as moisture level, pH value, temperature, humidity and the like need to be tracked periodically for the purpose of irrigation. For tracking the soil and environmental parameters, conventionally a network of sensors is deployed in the geographical area/ agricultural field. The network of sensors is configured to capture environmental data corresponding to each environmental parameter and transmit this environmental data to a central server/ data processing unit. The number of sensors deployed in a specific agriculture land (i.e. sensor density) plays a major role in capturing the correct environmental data, since the soil conditions can vary from one portion of agriculture land to other. This result in the need of deploying a large amount of sensors placed in close proximity to each other so that the environmental data at desired granularity level can be captured.
[004] However, as the number of sensors increase, the overall power consumption by the sensors also increases. This situation turns even worst, when the sensors are battery operated. In order to save power consumption in such a network of sensors, currently most of the sensors in the network of sensors is kept in sleep mode and are activated after a predefined time interval. However, even if the sensors are kept in sleep mode, a considerable amount of energy is spent in the overall process of sensor data capturing.

[0016] As there exists a challenge in effectively managing energy consumption in a network of sensors the present invention as envisaged to manage power consumption in the network of sensors by selectively activating one or more secondary sensor nodes based on analysis of primary sensor data captured from one or more primary sensor nodes is illustrated. In one embodiment, one or more primary sensors and one or more secondary sensors are deployed in a predefined geographical area. The predefined geographical area may be an agricultural land. The primary sensors and secondary sensors are configured to optimally monitor environmental parameters of the predefined geographical area in real time. At any point of time a central data processing unit/ central server is configured to capture primary sensor data from the one or more primary sensor nodes. Based on the analysis of the primary sensor data, the central data processing unit is configured to determine whether the primary sensor data is sufficient to accurately determine environmental conditions in the predefined geographical area. If the primary sensor data is insufficient to determine the environmental condition, the central data processing unit is configured to transmit an activation signal to the one or more primary sensor node. Upon receipt of the activation signal, the one or more primary sensor node are configured to activate the one or more secondary sensor nodes. The one or more secondary sensor nodes, upon activation, are configured to capture secondary sensor data corresponding to the predefined geographical area and transmit the secondary sensor data to the central data processing unit.
[0017] In one embodiment, the central data processing unit is configured to optimize power and battery consumption of the secondary sensor nodes by dynamically activating or deactivating the secondary sensor nodes. In order to determine the number of secondary sensor nodes to be activated at a particular point of time, the central data processing unit is configured to analyze the primary sensor data with respect to a predefined threshold level. In one embodiment, the central data processing unit may determine whether to generate the activation or deactivation signal for the one or more secondary sensor nodes based on given topology of the predefined geographical area/ agriculture land, soil type, weather conditions, and the primary sensor data. The central data processing unit may also generate activation signal for activating the one or more second sensor nodes in case central data processing unit determines that the primary sensor data received is not of desired quality or contradictory to the expected primary sensor data.
[0018] In one embodiment, the primary sensor node may activate the adjacent node (secondary sensor node) by using a combination of actuator and physical switch. The central data processing unit allows for monitoring the predefined geographical area by using one or more permanently active sensor (primary sensor nodes). The one or more secondary sensor nodes are activated dynamically based on the activation signal received from the central data processing unit. The central data processing unit also enables visualization of the active and inactive sensor nodes in real time and information about cumulative battery savings.

In one embodiment, at least one primary node from the one or more primary nodes 112 is configured to communicate with an actuator. The actuator may be configured to operate a power switch corresponding to the one or more secondary sensor nodes 114. Further, the central data processing unit 102 may comprise a memory and a processor. The processor may be configured to execute programmed instructions stored in the memory for receiving primary sensor data captured by the one or more primary sensor nodes 112. The primary sensor data may comprise primary environmental data corresponding to a predefined geographical area 116. Further, the processor may execute programmed instructions stored in the memory to generate an activation signal, based on the comparison of the primary sensor data with a predefined threshold. Furthermore, the processor may transmit the activation signal to the actuator. Post receiving the activation signal, the actuator may operate a power switch, associated with one or more secondary sensor nodes 114, for activating the one or more secondary sensor nodes 114.

The memory 206 may include modules 208 and data 210.
[0026] The modules 208 include routines, programs, objects, components, data structures, etc., which perform particular tasks, functions or implement particular abstract data types. In one implementation, the modules 208 may include an environment monitoring module 212, a data analysis module 214, a secondary node activation module 216, an irrigation system activation module 218, and other modules 220. The other modules 220 may include programs or coded instructions that supplement applications and functions of the central data processing unit 102. The data 210, amongst other things, serves as a repository for storing data processed, received, and generated by one or more of the modules 208. The data 210 may also include a local repository 226, and other data 228. The local repository 226 is configured to store primary sensor data and secondary sensor data received from the one or more primary sensor nodes 112 and one or more secondary sensor nodes 114. The local repository 226 may further be configured to store threshold levels to be compared with the primary sensor data received from the primary sensor nodes 112.
[0027] In one embodiment, the environment monitoring module 212 is configured to receive primary sensor data captured by one or more primary sensor nodes 112. The primary sensor data comprises primary environmental data corresponding to the predefined geographical area 116. The primary environmental data may correspond to at least one of temperature level, moisture level, pH value, and water level associated with a zone in the predefined geographical area 116.
[0028] Further, the data analysis module 214 is configured to generate an activation signal, based on the comparison of the primary sensor data with the predefined threshold levels sorted in the local repository 226. In one embodiment, the one or more primary sensor nodes 112 and the one or more secondary sensor nodes 114 may be battery powered.
[0029] Furthermore, once the activation signal is generated, the secondary node activation module 216 is configured to transmit the activation signal to the actuator. The actuator, after receiving the activation signal, is configured to operate a power switch associated with the one or more secondary sensor nodes 114, for activating the one or more secondary sensor nodes 114. The one or more secondary sensor nodes 114, on activation, are configured to capture secondary sensor data. The secondary sensor data comprises secondary environmental data corresponding to the predefined geographical area 116. The secondary sensor data may also includes battery level information corresponding to the one or more secondary sensor nodes 114. Further, the secondary node activation module 216 may also be configured to generate sensor deactivation signal for deactivating the one or more secondary sensor nodes 114 previously activated, based on the battery level information corresponding to the one or more secondary sensor nodes 114.
[0030] Once the primary sensor data and secondary sensor data is captured, the irrigation system activation module 218 may initiate at least one irrigational activity in the predefined geographical area based on analysis of the primary sensor data and the secondary sensor data. The irrigation activity may correspond to switching on/ off an irrigation pump in the predefined geographical area 116.
[0031] Figure 3a, 3b, and 3c represents activation process of the secondary sensor nodes, in accordance with an embodiment of the present subject matter. At any point of time the deactivated sensor nodes in the predefined geographical area 116 are represented by grey color. It is to be noted that the deactivated sensor nodes are completely switched off and not in standby mode. Since the deactivated sensor nodes are completely switched off, there is no energy/ battery power consumed by the deactivated nodes, as compared to sensor nodes that are maintained on standby mode in the conventionally used sensor networks.
[0032] Referring to figure 3a, initially the one or more primary sensor nodes 112 that are deployed in zone 1 are activated. The one or more primary sensor nodes 112 capture and transmit the primary sensor data to the central data processing unit 102. The central data processing unit 102 may analyze the primary sensor data and determine whether the primary sensor data is sufficient to initiate irrigational activities in the predefined geographical area 116.
[0033] Referring to figure 3b, if the primary sensor data is not sufficient for conducting the irrigational activity, the central data processing unit 102 may generate an activation signal for activating one or more secondary sensors 114 in zone 2. It must be noted that the secondary sensor nodes 114 in zone 2 are in immediate proximity with the one or more primary sensor nodes 112. The secondary sensors nodes 114 in zone 2 may be activated with the help of an actuator configured to operate power switch of the secondary sensors 114 deployed in zone 2. The actuator may receive activation signal from the central data processing unit 102 for activating the secondary sensor nodes 114 in zone 2. Upon activation, the secondary sensors nodes 114 are configured to transmit the secondary sensor data to the central data processing unit 102. The central data processing unit 102 is further configured to analyze this secondary sensor data in order to initiate irrigational activities in the predefined geographical area.
[0034] Referring to figure 3c, if the secondary sensor data is still not sufficient to determine irrigational activity, the central processing unit 102 is further configured to activate one or more secondary sensor nodes 114 deployed in zone 3, zone 4 and so on and so forth, till the central data processing unit 102 is able to correctly determine the irrigational status and environmental condition in the geographical area 116. The pattern of activating secondary sensor nodes shown in figure 3a, 3b and 3c is one possibility of deploying the claimed invention. However, the starting point of every possible combination of activating secondary sensor nodes is to capture primary sensor data from the primary sensor nodes 112.
[0035] Referring now to figure 4, a primary sensor node is disclosed. The since the primary sensor nodes 112 are permanently active a trigger switch to activate the primary sensor node is absent in the primary sensor nodes.
[0036] Further, figure 4 discloses the primary sensor node 112 and secondary sensor node 114. The primary sensor node and the secondary sensor node may comprise of required type and number of sensors (e.g. moisture sensor, temperature sensor, pH calculator etc.) represented by sensor module 1 to sensor module 3 and so on and so forth. The data (primary sensor data) captured by the sensor modules of the primary sensor node 112 is continuously sent to the central data processing unit 102 hosted over a server using the available connectivity modules 404 (e.g. 3G, 2G etc.). The central data processing unit 102 is configured to analyze the incoming primary senor data. Based on the analysis the central data processing unit 102 transmits an activation signal to the primary sensor nodes for activation the secondary sensor node 114 in immediate proximity of the primary sensor node 112. The primary sensor may, after receiving the activation signal from the central data processing unit 102, may operate the actuator 402a to activate or deactivate (switch ON or OFF as the case may be) the adjacent secondary sensor node 114. It is to be noted that in one embodiment, the actuator 402a may be in the form of a pneumatically controlled leaver which upon receiving the activation signal operated a power switch of the secondary sensor node for activation or it can be a wire in which current is sent when the neighboring secondary sensor node needs to be turned ON. The secondary sensor node may further comprise a second actuator 402b for activating a secondary sensor node in the neighborhood. In one embodiment, the central data processing unit may analyze the data received from the primary sensor nodes 112 or the secondary sensor nodes 114 and may generate a visualization of active nodes. This visualization may be displayed over the user devices 104 connected to the central data processing unit 102. The sensor activation, deactivation information may be viewed using smart glasses wherein the view of the field is superimposed with the set of active (and/or inactive) nodes.

The method 500 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, functions, etc., that perform particular functions or implement particular abstract data types. The method 500 may also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, computer executable instructions may be located in both local and remote computer storage media, including memory storage devices.
