这是一个用远距离监视盘来监视煤矿井下瓦斯的系统。在矿井里,每隔一定距离安装一个瓦斯传感器,为了把瓦斯传感器的检测信号输送给监视盘采用多路传输系统。随着井下作业的进展距离变长,因此每次都必须增设瓦斯传感器,但在多路传输系统中,只要在已设的传输线上增设发送部件就行了。把发送部件接在各瓦斯传感器上,并用两根传输线把发送部件连接起来。
This is a system that monitors long-distance monitoring of coal mine methane. In the mine, at a certain distance to install a gas sensor, in order to send the gas sensor detection signal sent to the monitoring disk using multi-channel transmission system. As downhole work progresses longer distances, gas sensors must be added each time, but in multiplex systems it is only necessary to add sending components to the existing transmission line. Connect the sending part to each gas sensor and connect the sending parts with two transmission lines.
