The station coding technology is the general name of the track circuit forwarding or superposition of locomotive signal information technology. This technology is mainly applied to the railway station, to ensure the code track circuit within the station will transmit the required information to the locomotive onboard equipment continuously, so that the train can receive the forward signal display continuously during the operation within the station.The station coding technology is mainly applied to the railway station, to ensure the code track circuit within the station will transmit the required coding information to the locomotive onboard equipment continuously. So, it is one of the basic equipments for the traffic control system. The station coding technology is broadly applied in the railway signal. The safety and reliability is the first after the railway is speeded up. Hence, the correct use of the coding is critical. With the further speeding up of the railway in future, it will put forward higher requirement for coding, and the coding technology will be further revised and perfected according to the requirement for development.The station coding equipment is one of the basic equipments for the traffic control system, and the coding equipment is the ground equipment of the locomotive signal system, so it is necessary to provide the correct locomotive signal information within the rail.
