Design of Wireless Monitoring and Control System of Small Coal Mines Based on GSM

Aiming at the problem that digital remote monitoring and control system of coal mine is difficult to realize in small coal mines,the paper presented a design scheme of wireless monitoring and control system of small coal mines based on GSM,and introduced supervision mode,general structure and communication method of the system.The system realizes the wireless monitoring and control of small coal mines by use of technologies of GSM wireless communication and radio frequency.
