Abstract

The invention discloses a coal mine safety monitoring system having a write protection function and belongs to the technical field of coal mine safety monitoring. The coal mine safety monitoring system comprises a gas sensor, a temperature sensor, a mine earthquake sensor, a signal processing circuit, an alarm circuit, a short-range terminal, a write protection module and a remote terminal, wherein the write protection module comprises a voltage division circuit composed of a capacitor and resistors, the voltage division circuit is connected with an integrated reset chip, the output end of the integrated reset chip is connected with two phase inverters mainly composed of transistors sequentially, and the output ends of the phase inverters are connected with the short-range terminal. The coal mine safety monitoring system monitors the working environment of a coal mine round the clock. Once a hidden danger is found, workers who are performing operation and a remote monitoring system are timely informed to facilitate timely evacuation of the workers performing operation from a site and taking of rescue measures of the security department, so that the disaster loss is minimized.

Description

technical field [0001] The invention relates to a coal mine safety monitoring system with a write protection function, belonging to the technical field of coal mine safety monitoring. Background technique [0002] In recent years, coal mine safety accidents have occurred frequently, so the safety of coal mining is particularly important. Various coal mine safety monitoring systems emerged as the times require. [0003] The application number is 201310647458.1, and the application date is December 2, 2013. The invention patent application discloses a coal mine safety monitoring and monitoring system. The monitoring host is connected to the underground ring network platform through the network switch, the network switch is connected to the server, and the terminal equipment is connected to the ring network platform. , receive the signal sent by the monitoring sub-station long-distance, and send it to the host for processing; receive the signal from the host, and send it to th...
