Research And Development Of Automobile Calibration System For Combines Meter Of D310

With the fast development of the automobile industry, the development of the automobile instrument is also more and more quick. The large quantity production of the automobile instrument brings another problem, which is how to calibrate the volume-production. The automobile instrument is the information center of the modern automobile; its quality determines the drive safety and the quality of the car. Because the fast change of the automobile instrument, the new product appears continuously and the old instruments are in the use, how to develop a calibration system which can calibrate different model of instrument becomes an important topic and is very rich in application.This topic that aims at the instrument of the D310 series car develops an all-purpose combination system for combine instrument, used for the circuit board examination, the parameter writing, and the procedure load and assembly calibration before the use. The hardware of the examination system mainly includes the resistance network module, the voltage control module, the power supply module, CAN and RS232 communication interface module, the software is composed by data module, parameter writing module, CAN and RS232 communication module, instrument and light circuit examination module. You can get the makeup and principle of the hardware and main structure and the design theory of the equipment software; at last develop a valuable comprehensive examination system for D310 automobile combine instrument.
