, Description:FIELD OF THE INVENTION:
The present invention relates to the field of water supply and drainage. The present invention more particularly relates to a dynamic system drainage monitoring system using IOT (Internet of things).
BACKGROUND OF THE INVENTION:
The underground drainage system is an important component of urban infrastructure. It is considered to be city’s lifeline. Most management on underground drainage is manual therefore it is not efficient to have clean and working underground system. Also in such big cities, it is difficult for the government personnel to locate the exact manhole which is facing the problem.
Drainage system monitoring plays an important role to keep city clean. In fact, not all areas have drainage monitoring team. It leads to irregular monitoring of the drainage condition. The irregular monitoring leads to the blocking of the drainage that imply to the salutation which trigger flood. Manual monitoring is also incompetent. It requires a professionals but they can only monitor very finite and maintain low accuracy. Also sometimes due to lack of knowledge the worker may meets to an accident as they have no idea about the conditions in those manhole.
Drainage system plays a very important role in big cities where millions of people live. Drainage system is known as the base for land dryness from the excess and unused water. Rainwater and waste water. Drainage conditions should be monitored in order to maintain its proper function. In fact, not all areas have drainage monitoring team. It leads to irregular monitoring of the drainage condition. The irregular monitoring has contribution on the blocking of the drainage that imply to the salutation which trigger flooding in the neighborhood. Manual monitoring is also incompetent. It needs a lot of dedicated persons who are only able to record limited report with low accuracy. The problem arises in such drainage lines can cause serious issues to the daily routine of the city. Problems such as blockage due to waste material, sudden increase in the water level as well as various harmful gases can be produces if the proper cleaning actions are not taken time to time. Today’s drainage system is not computerized due to which it is hard to know if blockage is occurring in particular location. Also sometimes due the waste in those drainage lines can produce various gases like methane (CH4 ), carbon monoxide (CO), etc which are harmful and can cause serious problem if inhaled by humans in large amount and these problems are generally faced by the drainage workers due to which death can occurs. Also we don’t get early alerts of the blockage or rise in amount of those gases or the increase in water level. Hence detection and repairing of the blockage becomes time consuming and hectic.
The existing drainage system is divided into a number of links, each link has run correlation, basically the current situation: a separate network monitoring unit, independent of the static network model analysis, independent automation units, etc. They are not interconnected, and no operation monitoring system with intelligent analysis of the relevance of practical rules.
Therefore, it is essential to develop a system which can handle underground drainage without human intervention and a smart and real-time Drainage and Manhole Monitoring System with the help of Internet of Things. Underground Drainage involves sewerage system, gas pipeline network, water pipeline, and manholes. The present invention includes various functions used for maintenance and monitoring of underground drainage system and provides a system which is able to monitor the water level, atmospheric temperature, water flow and toxic gasses. If drainage system gets blocked and water overflows it can be identified by the sensor system. And that sensor sends information via the transmitter which is located in that area to the corresponding managing station.

The manholes present in the drainage have a module which is having microcontroller interfaced with gas sensor, level indicator, NRF. The system monitors if the blockage is occurred in between two manholes and also it senses the rise in amount of various gases which are harmful to the human beings, and also a system of monitoring the water level then it triggers an alarm and provides those information to the health departments from which the particular action is taken. The system monitors all these things in real-time scenario which allow the persons to take proper actions of the particular problem in drainage system. The present invention provides higher level of precision than wired network system with respect to cost; flexibleness and reliability to replace hybrid or combined technology

DETAILED DESCRIPTION OF THE INVENTION WITH RESPECT TO DRAWINGS:
The present invention provides a system which can handle underground drainage without human intervention and a smart and real-time Drainage and Manhole Monitoring System with the help of Internet of Things. The present invention provides maintenance and monitoring of underground drainage system and provides a system able to monitor the water level, atmospheric temperature, water flow and toxic gases. The present invention helps to block drainage system and overflow water which can be identified by the sensor system and that sensor sends information via the transmitter which is located in that area to the corresponding managing station and to provide higher level of precision than wired network system with respect to cost; flexibleness and reliability to replace hybrid or combined technology.
In one embodiment, Sensors are used to detect blockage, flood and gases. The intelligence of sensors and system identifies the clogging inside the drainage system and gives the details of the location and other information for further actions. The details of the location and other information is sent to the database of the website through which user registration is carried out. The system also senses the presence of various harmful gases such as Methane (CH4), Sulfur dioxide (SO2), Carbon monoxide (CO) etc. As the level of such gases pass the threshold value, the system generates the alert using alarm system by which the Health department takes proper action on it. The system of the present invention is implemented using Wireless Sensor Networking (WSN) technology. Each node carries its own data along with the data of neighboring node and pass it to next node by hopping techniques. These entire data packet is collectively sent by the gateway node and stored at the cloud all these data is accessible in real-time scenario for continuous monitoring.
In another embodiment, The drainage channels are covered with manholes to operate and to clear the blocking present inside the channel. By placing the sensor node inside of the manhole detects and transfers the appropriate sensed information about the blockage, harmful gases and conditions to detect elevated flow levels of drainage system. Using the communication unit, it communicates with the sensor nodes places at nearby manholes. This data is then transmitted to the base station for further analysis. Sensors monitors the water levels, blockage in drainage as well as amount of hazardous gases in real-time scenario. Based upon the data values given by the sensors in drainage system the information along with location ID sends to the Gateway and that sends to cloud (server) (database of the website) or concerned authority
In another embodiment, Based on drainage monitoring guidelines, the monitoring parameters are monitored.1.Blockage in between two manholes.2.Detection of hazardous gases.3.Detection of water level. So the sensor that we need is water level sensor, sensor for blockage detection and gas detection sensor. Water level sensor is used to determine the water level. If the water level increases while the rainfall and water discharge normal it means that occurs salutation in the channel. Similarly the gas sensor is used to measure the presence of particular gases as well as amount of those gases. Various gas sensors are used to sense the gases such as carbon monoxide (CO), sulfur dioxide (SO2), methane (CH4).
In another embodiment, Hardware on the node includes sensors, signal conditioning, gas sensor, raindrop sensor, processor, RTC (Real time Clock), RF (Radio Frequency) modules and supply units. The RF module requires minimal power and provides reliable delivery of data between remote devices. The modules operate within the ISM (Industrial, Scientific and medical) 2.4GHz frequency band. The output of water level sensors, gas sensor and blockage sensor conditioned as standard input signal for microcontroller. Output of signal conditioning is input to the Microcontroller. RTC set the time of data collection and then RF Module send the data to other sensor nodes. Supply unit can be either battery or solar cell give the power to the sensor node.
The gateway is sensor node that has additional functions to send data to the server. The communication mode that used in this design is GSM/Wifi connection. This component is used to send the entire collected data packet to the cloud where it is stored for further use. Sensors from all nodes sense the gas and water levels at particular time intervals this data is hopped from node 1 to node 2 and node 2 to node 3 .
