Research on Key Technology of Platform Screen Door Control System for High-Speed Railway

摘要

Platform screen door (PSD) control system is a complicated distribution parameter control system. It integrates construction, machinery, electronics control, and other disciplines at an organic whole. Aiming at the problem of low localization of the original PSD products, the paper realizes the autonomy of two core technologies, door machine and door control. Control system can be divided into signal system level, local control level, and the manual operation of three control levels from high to low order. The key technology realizing the platform screen door system can be divided into the central control panel design, gating unit design, and software design. At last, the model machine of control system has been tested in platform screen doors controlling experiment. The test results show that the system has an excellent dynamic performance and a high reliability, and thus the validity and the feasibility of the proposed approach are proved. The system has the advantages of high national productivity, reducing project cost, and owning independent intellectual property right.
