Design and implementation of multi-function vehicle bus controller and testing/monitoring equipment for railway vehicles.

This paper introduced the design and implementation of a multi-function vehicle bus controller with completely China-owned intellectual property. It also covered the development of the corresponding monitoring and testing equipment. The core functionality was implemented on both FPGA based firmware and ARM based software. It developed the whole system with a design-for-reliability methodology. In addition to various self-monitoring and auto-recovery design features, the whole system had been statically checked and field tested with state-of-the-art hardware and software verification techniques. Moreover, it also adopted a modular design styles so that the hardware and software modules could be integrated into a whole spectrum of products with varying admiration and communication capabilities. Thanks to the modular design style, it also introduced a realtime MVB traffic monitoring device and an automatic product tester. With world-leading performance, the proposed MVB controller has passed the IEC61375 conformance test and 20 000 km fault-free operation in a metropolitan subway system. [ABSTRACT FROM AUTHOR]
