The test results are as follows: (1) the upper machine can display real-time running speed, belt tension, drum temperature, motor and gearbox temperature, motor current and other parameters, with an error of no more than 5%. It can detect the faults such as deviation, smoke, coal stacking, longitudinal tearing in real time, and the reaction time is less than 1s. (2) The system can realize centralized control, local control, maintenance control, emergency stop control along the line, etc. (3) The functions of system fault voice alarm, start stop alarm, public address call, point alarm, etc. are normal. (4) The system can protect the faults such as deviation, coal stacking, smoke, speed, temperature and tear, and locate the fault points.
