摘要
针对传统手持式汽车故障诊断设备的不足,为了能够在线监测和诊断汽车故障,将蓝牙(Blue tooth)、CAN(Controller Area Network)总线、智能手机三者结合在一起,构建基于蓝牙技术的汽车无线故障诊断系统。该系统能满足对汽车诊断技术的实时性和移动性的需求,实现对汽车发动机OBD-II的无线故障诊断。本文详细地描述了构建的技术方案、系统结构、通信协议和软硬件实现电路。
Aiming at the shortcomings of traditional handheld fault diagnosis devices for automobiles, a wireless automobile fault diagnos tics system based on Bluetooth technology is constructed by combining Bluetooth, CAN（Controller Area Network） bus and smart phone so as to monitor and diagnose automobile faults online. The system can meet the real-time and mobile demands of automobile diagnosis technology, and realize the wireless fault diagnosis of automobile engine OBD-II. This paper elaborates the technical scheme, system structure, communication protocols and software/hardware circuits.
