摘要
为了满足车载电源多模块监控的实时性、可扩展性、灵活性、可靠性等需求,采用LPC2294作为监控模块主控芯片组建了监控网络,对带DSP控制器的逆变电源模块、开关电源模块和蓄电池控制模块通过CAN总线进行监控;另外监控模块通过工业以太网与PC机连接,实现系统的后台监控。重点介绍了监控模块的软硬件设计及CAN总线应用层协议的具体制定和实现。
In order to meet the realtime,expansibility,flexibility and reliability requirements of the vehicle power supply multi module monitoring,the monitoring system adopts LPC2294 as the main control chip for constructing monitoring network to monitor inverter power supply module with DSP controller, switch power supply module and control module for the storage battery. In addition, through the industrial Ethernet connect the monitoring module and PC, to achieve the background monitoring. The hardware and software design of monitor module and protocol of the application layer for CAN are mainly introduced.
