Design of driver controller for coal mine-used electric locomotive based on PLC

In view of the existing problems of electric locomotive，the paper proposed a new control scheme for driver controller based on PLC. Through the acquisition of voltage，current，speed，obstacles and other information，the intelligent control of electric locomotive can be achieved. The interface circuit of PLC was designed，as well as speed detection circuit，HMI interface circuit，and motor main circuit. The application shows that the system has solved the problems well and reduces the work intensity，improves the level of automation of motor vehicle，it has a strong promotional value.
