Design And Implementation Of Coke Oven Vehicles Automatic Orientation System

Coke oven vehicles are the main equipment in coke production, among which the pusher car, the guide car, the quenching car, the charging car and the dust car must work together in order to ensure the safety and efficiency in the coke producing. Therefore, increasing the level of automation of the coke oven vehicles is very significant.This paper, on the basis of the in-depth research and analysis of the existing coke oven vehicles automation system at home or abroad, designed and realized a kind of low cost, stable, and high-performance coke oven vehicles automatic orientation system. This system adopted the code card identification to detect the coke oven vehicles’address, and used the infrared electric sensor correlation technology to read the absolute address coded by the code card at the fixed-point to correct the offset address outputted by the absolute encoder, and then finally got an accurate address of the coke oven vehicles; Used the GE MDS SD9-MS wireless digital radio to establish a reliable wireless communication network between the control room and the five coke oven vehicles, in order to realize the centralized control and management of the five coke oven vehicles by the industrial computer in the control room; Adopted the automatic traveling and automatic orientation technology based on the stepless speed regulation, and according to difference between the target address in the production plan issued by the industrial computer and the actual address of the coke oven vehicles, it could control the speed and direction with the vehicles by the variable frequency speed regulating device, and then made the vehicles go and stop at the target address automatically and precisely.The results show that the coke oven vehicles automatic orientation system can achieved the lmm level of address detection resolution, the wireless communication network was reliable and stable with low bit error rate, the accuracy of the automatic orientation was up to+10mm, it completely satisfied the requirement of the coking production process, and had a high economic value.
