[0002] Railway signal technology is the infrastructure of railway transportation, and is also an important equipment to ensure driving safety, improve transportation efficiency and improve working conditions. Modern railway signal technology has become an important means to provide real-time information to transportation organizers, realize effective train control, improve railway section capacity, and improve marshaling capacity. It is also one of the key technologies for railway train speed-up and the development of high-speed railways. Railway signal technology has gradually integrated with communication and computer technology in the information age. With the development of information technology and network technology, the traditional concept of railway signals is changing, and the function of signals is gradually expanding. Railway signals have changed from the "eyes" of railway transportation in the past to the "central nervous system" of railways, playing an increasingly important role. As an indispensable means of railway transportation information operation management, railway signals occupy a very important position in railway transportation, and their development level has become one of the symbols of railway modernization.

[0003] The application of relay circuits in railway signal equipment is very extensive. During the study of traffic information engineering and control in colleges and universities, due to the lack of on-site equipment or the non-reproducibility of the on-site operating environment, railway signal simulation experiments are used for theoretical research. The railway signal simulation experiment simulates the working process of the circuits of power equipment such as relays. The railway signal simulation experiment is also carried out in conjunction with the user interface to logically realize the working mode of power equipment such as relays.

[0004] However, traditional railway signal simulation experiments have the following disadvantages:
