基于VB及AVR单片机的汽车整车智能考核系统设计

摘要

Designed auto intelligent evaluation system,which is divided into hardware and software,the main function of the hardware is the intelligent control board based on AVR single chip, the intelligent control board which contains resistance measuring, voltage measuring,open circuit fault setting and virtual fault,short measurement communicate with PC by WIFI network through USR-WIFI232 module, and the voltage of the board measured by ADC module. The intelligent main control abroad consist of many single chip circuit boards, which communicate with each other through TWI, the software consist of PC application system developed by VB, it is mainly used to teaching in the net,displayed the complex automotive circuit vividly to make the students understand the network failure better, the fault type contains open circuit fault,virtual fault,and short circuit,the voltage and resistance of the tested circuit measured by the net to rule out the net fault and manage the test intelligently.%设计了汽车整车智能考核系统，分为硬件和软件部分。硬件部分主要功能是基于AVR单片机设计的智能主控板，智能主控板通过USR-WIFI232模块与PC进行WIFI网络通信，通过ADC模块测量被考核系统的电压，包含电阻测量、电压测量、断路故障设置、虚接故障测量、短路故障测量；采用多块单片机电路板设计，电路板之间通过TWI通信。软件部分是用VB开发的PC应用系统，软件的功能主要包含：网络教学，将复杂的汽车电路形象地显示出来，便于学生理解；网络设置故障，故障类型包含：断路故障、虚接故障和短路故障；网络测量被考核电路的电压和电阻参数；以及进行网络排除故障，智能化的考试管理功能等功能。
