Abstract
The invention discloses a coal mine protecting device facilitating monitoring point movement. The coal mine protecting device comprises gas sensors, a controller, wireless transmission modules and a power control device. Each wireless transmission module comprises a transmission module and a receiving module which is in wireless connection with the transmission module. The signal output ends of the gas sensors are connected with the signal collecting ends of the transmission modules. The output ends of the receiving modules are connected with the signal collecting end of the controller. The signal input end of the power control device is connected with the signal output end of the controller. The coal mine protecting device replaces existing manual multi-point detection carried out on a mine, monitoring point movement and replacement and installation of the coal mine protecting device are convenient, no human factor intervention is needed for signal judgment and power supply cut-off, and all devices connected with the power control device are forcibly stopped when the gas content exceeds the set value, so that the reliability is high, and the monitoring input is small.
