The coal yard is an important place for coal storage. Since coal spontaneous combustion and personnel poisoning incidents often occur during the coal storage process, the safety of coal storage is very important. The coal yard must install a safety monitoring system to ensure the safety of coal storage. The coal yard monitoring system mainly monitors several factors such as temperature, toxic gas (CO), combustible gas (CH4), open flame, etc., so as to ensure the safety of coal storage. So far, most domestic coal yard monitoring systems have adopted the traditional wired transmission method, that is, the signal acquisition, communication, and control of each part of the monitoring system are completed through cables, and the on-site environment of the coal yard It is more complicated, and the transmission distance between the coal yard and the main control room is relatively long, so the wired transmission method has the following disadvantages:
