新型高可靠性列车运行监控装置
A New Highly Reliable Train Operation Monitoring Device
摘要
Abstract
The controller is the backbone of the new train operation monitoring device. Its network structure includes two layers: the control layer and the communication layer. The integrity of the control functions can be assured by the layered network. The reliability of module-level redundancy and system-level redundancy is analyzed and compared. On this basis, the better module-level redundancy is adopted for the new train operation monitoring device. Also, the scheme for designing the hardware redundancy switching circuit and the intelligent modular input/output module is proposed. Large capacity CF card is used as the carrier for the dump of ground basic data. By applying MD5 code verification technology and data redundancy storage technology, the ground basic data in the on-board host computer and the display has been automatically fully updated at the same time. The train operation monitoring device has improved both the security and usability for updating ground basic data. Ground tests and service running tests show that the device has basically met the current requirements for train operation and thus can guarantee the safe train operation control.关键词
