Case Study of Localization of Metro Vehicle Bus Manager (VTCU)
The on-board bus manager is the core component of the train bus management system. It is directly responsible for monitoring the actual running status of the train, determining the status of each subsystem in real time, and feeding back fault information of the abnormal components to the driver's cab human machine interface (MMI). 插件主要用于连接MVB总线、转换列车总线WTB和车辆总线MVB之间的数据。 The vehicle bus management plug-in is mainly used to connect the MVB bus, convert the data between the train bus WTB and the vehicle bus MVB.
Xinxin Technology undertakes the repair of this plate and the research and development of domestically produced independent intellectual property rights spare parts products. 板件已通过某地铁公司地面台架测试，正在进行正线跑车试验，各项性能达到与原型板件替换使用的程度。 At present, the on-board bus management board has passed the ground test of a subway company and is undergoing the test of a sports car on the line. Its performance has reached the level of replacement with the prototype board.
The following is a brief introduction to the hardware features:VTCU），该单元每3节车厢一个控制单元, 共由7 块板组成, 自带插槽和电源, 是标准的模块化系统。 The main component of the bus manager is the vehicle control unit ( VTCU), which is a control unit for every 3 cars, consisting of 7 boards, with its own slot and power supply. It is a standard modular system. 由网关( VTCU- GW) , VCUT,VCUA 及VTCU 的电源组成。 VTCU consists of gateway (VTCU-GW), VCUT, VCUA and power supply of VTCU. The gateway controls the train bus (WTB) and vehicle bus (MVB), and converts process and information data between the two bus systems. There is an on-board database (ODBS) on the train diagnostic board VCUT, which can control the man-machine interface through the RS422 interface. The train application board VCUA contains train and vehicle control programs. The VTCU's power supply provides 110V DC power and is isolated from the potential of the power supply system.
