General CAN (controller area network) monitoring method based on network protocols

The invention provides a general CAN (controller area network) monitoring method based on network protocols. In the method, a configuration file technology is adopted, wherein a configuration file comprises the address, the number, the meaning, the attribute and other information of a lower controller; and an upper computer is used for establishing an interface to monitor the lower controller by calling different configuration files related to the network protocols and displaying or storing information related to equipment. The functions and the information in a software interface of the upper computer are refreshed in accordance with the changes of the configuration files, so that the equipment can be monitored based on the different network protocols by modifying the configuration files only, the monitoring requirements of the equipments with the different network protocols are met and the equipment has better generality.
