Abstract
The use of rail transport tunnel mine special explosion - proof motor vehicle battery power meteralarm erection of methane ; When the electric locomotives of methane to preset values in a concentration, sensors could send a signal of audible visual type. If the methane concentration to another preset weights, they can cut off the motor car alarm hostcontroller power ,to avoid the danger zone again driving the motor vehicle. Therefore, vehicle - mounted power meter of methane alann routine to strengthen inspection and maintenance to ensure their devices to work properly.关键词
