Abstract The present paper through the discussion elevator control system choice and the introduction, elaborated programmable controller (PLC) in the elevator control application, uses Mitsubishi the PLC programming the procedure control mode, proposed five floor elevator PLC control system overall project designs, the design process, the composition, have listed the concrete main hardware electric circuit, the elevator control trapezoidal chart and the instruction list. And has given the system composition diagram and the program flow diagram, in the analysis, in the processing random signal logic relations foundation, proposed the PLC programming method, has designed a set of complete elevator control system plan. Uses this plan realization elevator control, can solve the relay contact device electronic contact to be many, the failure rate high, the reliability bad, installs the debugging cycle long, the service work load big, the wiring complex and so on the shortcomings. Causes the elevator movement to be safer, to be convenient, is comfortable.

The touching screen all had the application in very many aspects, this article introduced simply the touching screen knowledge, and has drawn the elevator surveillance picture with the GT Designer2 software, caused the elevator the movement even more clear security.

Key word: Three elevators, touching screen, PLC, automatic control
