Rail Transportation Automatic Door Remote Intelligent Monitoring, Diagnostics And Maintenance System

With the rapid development of rail transit, there are higher requirements for safety, comfort and using convenience of railway vehicle and its kit equipments. The auto-door system is an important part of railway vehicle. But its high fault frequency has heavily destroyed the railway vehicle's reliability. The problem is urgent and needs to be solved.After an analysis of the current development and problem of rail transit, the paper combines with various information technology, artificial intelligence, etc and puts forward the Remote Intelligent Monitoring, Diagnosis and Maintenance System of Rail Transit Auto-door (TRAD-RIMDMS), aiming at accomplishing the auto-door's fault diagnosis & maintenance with lower cost, less time and better effect. Then a networked, distributed, multimedia communication platform is developed based on Internet and the Public Switched Telephone Network (PSTN). TRAD-RIMDMS is constructed on this platform. The system consists of the system management module, the remote monitoring sub-system, the device repair & maintenance management sub-system and the intelligent diagnosis sub-system. In the next part of the paper the system test plan is described in detail. And then the paper displays the system's running complexion and test results, which show that this system has fit in with the prescriptive technical requirement. At last the paper puts forward several points needed for improving and perfecting later.
