Universal Standardization of Signal Vehicle Interfaces for Urban Rail Transit

Objective Upgrading and modifying signal system is difficult, costly and time-consuming, greatly affecting the line daily operation during its modification stage. In order to solve the above problem, the signal vehicle interface should be standardized. Method By analyzing the installation interfaces for different signal systems, a compatible signal vehicle installation interface platform is proposed. Based on the composition and function of the onboard signal system, the standardization of the mechanical installation interface, electrical and control interface and network interface for signal vehicles is highlighted. On this basis, a general standardization solution for different device interfaces is put forward. Result & Conclusion The solution can match the equipment installation demands of different signal manufacturers to a great extent, and the interfaces of the existing vehicle installation platform don′t need great modification when the new signal system equipment is installed. It can effectively reduce the difficulty of signal system upgrading and the cost of modification, and improve the modification efficiency.
