Aiming at the practical condition of bad working environment and the high requirements of positioning control and running interlocking of coke oven locomotives, the automotive running control plan of coke oven locomotive based on induction radio is proposed in this study. This research proposes the methods of locomotive address detection, data communication and process control based on induction radio technology, and explores the principle and scheme of locomotive positioning control.The data exchange system between the four locomotives and the central control room of the coke oven is studied, which is used to suppress the interference of the double differential antenna receiving technology and the separation technology,especially frequency interference and co frequency interference.The application mode of multi locomotive positioning control in the same track is studied.The multi locomotive automatic walking and three dimensional control structures are constructed.Finally the proposed scheme is evaluated in order to meet the requirements of the automatic control of the coke oven.
