Design of automatic control system for coal conveying trestle in screening coal mine based on PLC Technology
The coal conveying trestle in the screening coal mine occupies a very important position in the entire coal conveying system.At present,the automatic control system for coal conveying in screening coal mines has a small difference between the coal transportation volume and the actual volume,resulting in low precision.In order to solve the above-mentioned problems,a new automatic control sys-tem for coal conveying trestle for screening coal mines was designed based on PLC technology.On the basis of the original PLC control,PLC extension modules and I/O modules were added,the system was reprogrammed,and the entire unloading system was changed to au-tomatic control,reaching unmanned control mode,and improving the safety and reliability of system control.The experimental results show that the automatic control system of coal conveying trestle for screening coal mine based on PLC technology can effectively improve the accuracy and precision of coal mine transportation calculation results.
