Abstract:

The normal sailing of a vehicle is determined by monitoring the presence of voltage of the important circuit and storing the CAN messages in communication.The voltage of the monitored circuits by the optical coupling TPL281-4 is connected to the pins of the microprocessor C8051F040.If no voltage exists,the time and the message are stored in the chip of AM29F160DT.The application results show that the monitoring circuit meets the design requirements.
