Abstract: The Safety Train Control (STC) system is a type of core safety guarantee equipment that supports the interlocking functions related to the autonomous train control system. The control method for the signaling equipment in the STC system has been optimized and designed on the basis of the control method for the signaling system in existing mature interlocking systems. The advantages of relay control and fully electronic module control are combined, and different control methods are adopted for different types of signaling equipment and according to the type and scale of the stations. The control method for the signaling equipment in the STC system not only inherits the features of intelligentization, electronization and networkization of fully electronic control, but also reduces the use of signaling relays during the on-site installation of signaling equipment, which reduces the construction and retrofitting costs of station equipment to some extent. This paper first introduces the STC system, and elaborates on its system functions and interface characteristics. It then describes the control methods of such signaling equipment as signals, switches, and scattered relays in STC system. It also analyzes the mapping principles of the fully electronic modules and relays in signaling system control of STC system, and describes the prospects of the future promotion and application of signaling system control of STC system in view of its advantages.
