Abstract: | In order to improve the efficiency timeliness and professionalism of diagnostic services,a remote diagnosis vehicle terminal based on GPRS network is developed in the article. The terminal system consists of 16 bit microprocessor ATmega128A, CAN bus controller MCP2515,GPRS wireless communi-cation module GTM900-C and GPS module. The system connects the car electronic control unit through the CAN bus. With the integration and package of the microprocessor, the data is sent to the remote com-puter server via Internet. This article introduces the principle, hardware design and software design of the remote diagnosis vehicle terminal system. And tests the real-time monitoring through engine bench test. The results show that, the terminal system is stable and reliable. It can be real - time monitoring of ECU. |
