Abstract: Some lines of intercity railway and high-speed railway have various models of vehicle and complex operation modes. The platform door system cannot implement linkage control with signal system, and manual control is adopted, which brings inconvenience to operators. In order to solve this problem, based on the analysis of the platform door control mode, this article designed an intelligent control system based on wireless communication technology and fieldbus technology to realize the remote control and status monitoring of platform door. The test results show that the system can control the platform door switch and check the running status of the equipment according to the set priority, which can meet the operation requirements and be widely used in the rail transit industry.
