Looking for the design of station signal simulation control system [Copy link]

If it is a bit difficult, which sensor can determine the occupied track section and how to draw the AD schematic diagram? Thank you very much.

Track occupancy can be detected by using an interrupter type photoelectric switch. If the model is small, a reflective type can also be used.

Thank you very much for your guidance. I'm sorry that I didn't express myself clearly above. What I need is how to determine whether the track circuit section is occupied in the railway signal system. Then I saw that I needed to use a sensor. I looked up the need for a Hall sensor, but I don't understand the information about that sensor. I looked up photoelectric switches, and it's a bit difficult to convert light signals into electrical signals. I don't know how to do it. Thank you very much for your guidance.

The Hall sensor is essentially a magnetic field sensor. The output signal is generally a switch signal that can be controlled by a microcontroller or other MCU.

There is a lot of information online, and this forum has video information.
