Therefore three-car interlock control is a very important part of coking production.

The automatic control of the coke oven vehicles, so called "interlocking system of three vehicles", is an important part of coke oven s safety production.

The construction companies usually have the simulation panel made up of knob switching board to simulate the outdoor track occupation, the release condition of signal and status of point, since the limitation and disadvantages of the simulation mode itself, the paper proposes the method for the intellectualization of station interlocking conduction test.

Based on analyzing the feature of computer simulation system and the requirements of railway signal,interlocking and blocking,the paper studies the method to implement station interlocking,section blocking and signal controlling in the simulation system of train reception/departure and control, highlights the discussion on general-purposed interlocking algorithm.
