Development of Coalmine Safety System Using Wireless Sensor Network
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 5
Abstract
In the Era of embedded technology, the Zigbee protocols are used in more and more applications. Because of the rapid development of sensors, microcontrollers, and network technology, a reliable technological condition has been provided for our automatic real-time monitoring of coal mine. The application designs a monitoring system for coal mine safety based on Zigbee wireless sensor network. The underground system collects temperature, humidity and methane values of coal mine through sensor nodes in the mine; it also collects the number of personnel inside the mine with the help of an IR sensor, and then transmits the data to information processing terminal based on ARM. The terminal sends the data to the ground section through Zigbee, and in the ground section, the processing terminal monitors the data and sends the data to the PC to save them and for remote users to inquire .An SMS is also send to the corresponding member through GSM modem which is connected to the controller. If any data is received, the received data is compared with the predefined threshold values, if the received values are more than the threshold values then buzzer will be on. So that warning to the personnel will occur.
