| Abstract: | 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. |
