| With the rapid development of telecontrol technology in the electric railway, it is necessary and exigent to train the professional operation ability of the staffs that operate the telemechanical apparatus. Therefore, much economic profit can be gained by studying and developing simulation teaching system.At present, each railway electric power supply section doesn't still have special instrument that can be used for training in remote technology. Meantime, there are only simulation teaching instrument without any interface in not only college but also professional school. This phenomenon affects the quality and the quantity in workers' training. This paper provides an electrification pc remote simulate system with interface through which can connect a group real traction transformer substation and simulated SSP, which make the function of simulated training instrument further more maturity and more closed to the real surroundings that running real instrument.Introduce the system's structure, composing and function of software and hardware.The system is based Win98 platform, adopt serial mode in communication between computers. The software is programmed with Borland C++5.0. the lines which is separated not only communicated each other in time, but also don't effect interfere transformer substation operation. In other word, when computers send and receive information's, it don't interfere real transformer substation operations. The system's software adopts parallel searching mode, which improve the system's rapid response ability.The hardware system adopts bus. The large circuit consist of circuit unit and obligate expanding interface, which strong the flexibility for system expanse, alteration and function appendence. It adopts parallel bidirectional communication between hardware and computer.Constituting connection between system and real transformer substation and simulated SSP, can set up simulated malfunction, which improve effect. The system possesses a certain spreading value.
