Research Of PSD Linkage Control System Based On 2.4G Wireless Communication

With the development of city railway traffic, PSD (Platform Screen Door) system has been widely applied. The signal system has to import some new functions to satisfy the request of PSD system. This article designs the PSD linkage control system to develope the signal system.In modern times most equipment providers need to update all of the signal system to add control function of PSD system. This scheme must modify both hardware and software design of signal system. The difficulty of design and construction will be increased obviously, and it's not suitable to upgrade the exist circuitry. The target system gathers necessary information and does the logic judgment in the base of old equipment. The information exchange between the train and upground devices adopts 2.4G communication mode. So this system can be applied to the majority of signal systems which are being used now inland. This design offers a better choice for the PSD addition of circuitry in existence.This thesis analyses the system function request and researches its design method. The system's hardware and software design is finished. Further more, this article also analyses the system security and gives the verification in theory.In the end, the test situation in the scene of the target system is illuminated. The test result is explained and analyzed too.
