Design Of Central Control Unit For Metro Train

With the rapid development and population growth of China’s economy, traffic problems in large cities has become a major problem hinder urban development, road due to limited resources, a simple expansion of the road is no longer the best option, therefore suitable for China urban rail transit construction is a good choice, urban rail transit has high capacity, small footprint, low energy consumption, low pollution and many other advantages, is the future direction of China’s large and medium urban transport development. September5,2012, the National Development and Reform Commission announced that approval of25urban rail transit construction projects at one-time. Approved a number of urban rail transit projects demand for the number of rail vehicles is self-evident. Central city rail vehicle control unit CCU is the heart of urban rail vehicles, but due to various reasons, the central control unit of China’s urban rail vehicle design CCU either from hardware design, software design or the relevant tests are still in its infancy, self-designed CCU running poorly, reliability is not high, the software is too extensive, of disarray, hardware and software upgrades inconvenience. The foreign transit vehicles CCU, technically we are blocked on the source code is not open, we can not understand the deep-seated structural CCU, so that the CCU for us is like a black box, it is difficult on the basis of secondary development.This paper is based on the " Dalian Metro Line3plus car project ", through the implementation of this project, and to explore the city a central control unit CCU rail vehicle design this topic x86-based high-performance processor architecture and high transplant reliability VxWorks embedded operating system and application software development platform embedded OpenPCS, and feature design application software elaborate, play a valuable role for the design engineering staff, and a breakthrough in the central control unit CCU abroad on technical barriers.The research topic for urban rail vehicles with independent intellectual property rights of a central control unit CCU, both from the design, upgrade, replacement, aftermarket have a strong advantage, can bring huge economic benefits. Finally, the CCU communication functions, applications were tested, The test results fully verify the urban rail vehicles designed in this paper a central control unit designed to achieve a localization requirements.
