Abstract:For a number of problems in the spray system used in the coal mine, put forward a coal mine intelligent spray real-time monitoring system design based on web technology, given the system composition, working principle, main function and key technology. The system uses web technology, integrated with other systems in the coal mine. The system is not only based on the real-time detection of dust, smoke, temperature, gas to spray automatically, but also on the ground real-time monitoring of underground environment and work status, and not need to go down to control underground spray system. The practical application shows that, this system realized mine environmental monitoring, smart spray and ground real time monitoring function.
