开发了基于Modbus总线的新型应急直流电源车电控系统,对系统功能实现作了分析,围绕电源车配电控制应具有的“四遥”功能(即遥测、遥信、遥控、遥调)及实时监测功能等进行了系统控制结构、主控单元、总线通信接口和节点硬件配置设计,通过主控模块实现与各单元的数据通信与控制连接,使得系统各单元状态参数清晰、准确的传输到电源集控装置。整套电控系统适应性强、供电迅速、使用便捷、操作安全,有效保障应急直流电源车应急供电的需要。
The new emergency DC power supply car electric control system based on Modbus is developed, and the function of the system is analyzed. The functions of “four remote” should be around the power distribution control (ie telemetering, remote signaling, remote control, ) And real-time monitoring functions of the system control structure, the main control unit, the bus communication interface and node hardware configuration and design, through the main control module and each unit of data communication and control connection, making the system state parameters of each unit is clear and accurate Transfer to the power control device. Complete set of electronic control system adaptability, rapid power supply, easy to use, safe operation, effective protection of emergency DC power car emergency power supply needs.
