Portable and Autonomous Gas Leakage Detection System
Project Area of Specialization RoboticsProject SummaryWe are working on a project for Sui Southern Gas Company Limited (SSGC).
Currently they get signal from SCADA automatically that within certain 20 km of distance there is a leakage detected. So to check for the exact location of leakage in that range of around 20 km, their worker takes a portable gas leakage detector with himself and check the whole area, of the specified range, by it.
We are making an automated gas leakage detection system for this problem. We are making a small autonomous car that will be fitted with the gas leakage detection system in it. The device will also be connected to GSM and will enable the internet and so by that the exact location of the leakage will be sent to the master’s computer automatically. The worker will take the car with himself and release it in the area of the specified range. The car will go on and check for the point of leakage itself.
Wherever there will be the leakage, the car will automatically send that exact location to the office and they will get notified instantly. The worker will not have to carry the portable leakage detector device in his hands and check for the point of leakage in the whole region of around 20km.
This project will provide an ease to the worker and also autonomously the chances of mistakes will be reduced and the solution will be improved.
The main purpose of this project is to design and make an efficient, better, smart, economic, portable Gas Leakage Detector.
The current portable gas leakage detector being used in one of the most famous gas supply company in Karachi, i.e. Sui Southern Gas Company Limited, is workable and functional for their required operations. However, keeping in view the modern progression of technology in the world, we intend to fabricate and formulate the improved, revised, form of this device in the form of an autonomous gas leakage detecting gadget.
We intend to reinovate the process of gas leak detection and make it portable and cost effective.
Project implementation (or project execution) is the phase where visions and plans become reality. In this project, our vision is to replace the duty of a man (to check the leakage from pipes daily) with a robot. So, the man have to charge the robot, enter the pipe's coordinates from Google map and the robot will start it's work until it will get problems of leakage.
Benefits of the ProjectGenerally gas suppliers or companies used conventional method to detect the gas leakage in surface mounted pipe lines this process is very difficult and expensive with operational errors and dangerous.
Due to above factors we resolve this process by a portable gas leakage detector (car robot).
Human safety: by using this robot to increase the labor safety and reduce the steps of detection.
Detection Speed: This robot not need to take break as compared to human it properly working till the leakage point traced out due to structural and wheel sizing its also helps the gain of maximum speed.
Cost effective: minimum cost with different variation as compared to manufacturer devices. Also reduce the paid labors.
Time efficient: To reduce the labor efforts and working against the obstacles itself.
Error reducing: Sensitivity of sensors it reduces the detecting process errors.
Technical Details of Final DeliverableA technical details defines the requirements for a project, product, or system. So the requirements of project are:
*) A automated car
*) A battery management system
*) Microcontroller
*) Methane gas sensor with display
*) A fully IOT based system to share and receive data
To move car forward and reverse relays are used and for automation ultrasonic sensors and servo motors are used.
To avoid any short curcuits and to make the batteries bidirectional, 4SBMS is used and then motors needs more voltages than other components, so DC-DC buck converters are used.
As our project is robotic type project so we choose adruino mega as our microcontroller.
Our main sensor is mq-5 sensor which will continusly read the methane's PPM in the environment and Arduino will check the readings.
GSM will work as a data sharing device in the project and if project detects leakage, the GSM send the location as well because GPS system is also here to get the location services.
