Designing of CAN Network Analyzer Based on SJA1000

Controller Area Network(CAN) bus has become increasingly important in numerous areas.It is meaningful to ensure its proper functioning.With controller SJA1000 as the core component,the thesis designs a CAN network analysis device, for on-site monitoring CAN bus operating conditions.The test result indicates that when accessed to the network,the device doesn’t affect the communication between CAN buses, just monitors the transferring messages and displays bus -error, baud-rate and so on.Such important parameters of CAN-bus are helpful to realize network disaster recovery.
