The system uses can bus to form a communication network and monitors kinds of parameters of the battery by means of self-designed can nodes. The system stores information collected in the CF card in the master node through can bus, or downloads the information to PC through the FTP server to analyze data. Serial communication between master nodes and PC through RS232 can show the information of the storage battery in real time. The system works stably and reliably in the test. It is easy to be used,and achieves the expected results. Key words:storage battery;CAN-bus;data collection |
