The control of railway switches is carried out with switch devices. The main control schemes are safe and are in the computer centralizations. Only power cables are installed next to the devices, through which commands for reversing the switches are given. The power cables are tied to the control scheme of the switch device. In this way, a very large amount of copper cable is consumed. This also affects the increase in construction costs in terms of the pipe network.

The article discusses a new approach in which the logic for controlling the devices is in a controller, which is installed in the device itself. The device control commands are sent from the station centralization via an optical cable to the controller. The controller decodes the command in a safe way and ensures the device`s reversal. Then the controller forms a telegram for the new state of the device and sends it back to the interlocking system. Communication between the interlocking system and the controller is carried out using a secure and safe Ethernet protocol. The controller allows it to be used for various types of devices in terms of the principle of electrical control. It is possible to additional sensors to control the position of the tongues. This allows you to optimize the number of copper cables in the station and to connect the switches into a common communication network. The article discusses the architecture of the control controller, the structure of the communication protocol and the principles of safe behavior after failure.
