Abstract: In view of problems of poor reliability, weak generality existed in traditional remote control devices, the paper designed a new type of remote control device of mining equipments, and introduced composition, hardware and software design of the device in details. The device adopts technologies of anti-interference design, communication error-controlling, detection of equipment state to improve reliability and generality. The practical application showed that the device can meet with control demands of large-scale mining equipments in coal mine at present.
