Embedded Auto's Remote Fault Diagnostic Apparatus

With the use of new materials, new technology and new technology in auto manufacturing process, the performance of vehicles has become increasingly good, and the structure has become more and more complex, which leads to the great increase in the difficulty of fault diagnosis. As People urgently need to improve the reliability, maintenance and safety of the vehicles. The projects with independent intellectual property rights described a embedded automobile remote fault diagnosis and maintenance system, which can be the timing of car / mileage for maintenance converted into real-time maintenance, the current high level of vehicle maintenance mode, and truly serve as a prevention Safeguard the role, and conscientiously improve the car is the stability and security. This paper is embedded on the car remote fault diagnosis and maintenance system and development of the historical background of the status quo of the existing technical characteristics, and the combination of future market demand, failure to embedded car remote diagnostics and maintenance system practical and concrete Research.Chapter 2 introduced the design applied to the related technology.Chapter 3 outlines the general framework of the system design, the overall system is divided into three parts: measurement terminals, handheld instrument and remote fault diagnosis and maintenance.Chapter 4 and 5, respectively, introduced the measure in detail the hardware design and end-driven design and definition of the measurement terminals and handheld instrument, remote diagnosis and maintenance of the system interface.Chapter 6 details on the handheld hardware design fault of the instrument. And chapter 7 of the whole system functions and features were summarized and made the further development of future direction.
