Design and realization of the vehicle-mounted unit for a remote electronic monitoring and calibration system

Abstract

This paper introduced the GPS/GPRS-based remote electronic monitoring and calibration system, as well as its working principle and system framework. Then the hardware structure and software designing of vehicle mounted unit were introduced. Next, we emphasize testing the reliability and speed of communications while refreshing the data of ECU through GPRS. As a conclusion, it quickly implements the functions of vehicle remote supervision and ECU calibration.
