| Along with the development of the fault diagnosis technology, modern faultdiagnosis technique has achieved from manual to intelligence to change. And forequipment’s remote fault diagnosis of the intelligent fault diagnosis system hasbecome one of the important performance. Wireless data transmission is one ofthe key points to the remote fault diagnosis system.How to improve the system real-time, reliability and also reduce the cost ofthe system, become wireless data transmission analysis system research focus,and wireless transmission system of communication technology is improvingtransmission system of real-time,the reliability of the key. GPRS mobilecommunication network technology development rapidly, using wireless mobilenetwork of wireless data transmission analysis system will have incomparableadvantage.In addition, people pay more attention to information security problem. Inorder to ensure the security of wireless data transmission, we should protectinformation in the source of data transmission, namely the terminal to protect.In order to research convenience, the subject chooses the typical pumper asthe research object, through in the pumper design and installation of the datatransmission analysis system, namely the vehicle terminal system, therealization of the high speed data, stability, security transmission, for remotefault diagnosis expert system to provide data on the strong support. And thissubject’s main job is:1The study analyzed the development of remote fault diagnosis datatransmission analysis system and overall structure of the remote fault diagnosis.2Analysis the vehicle terminal of pumper function requirement, buildterminal hardware platform.Design vehicle terminal,integrating embeddedmicrocontroller processor, memory chip,CANbus module, GPRS module,peripheral equipment.3Considering the terminal platform security, integrating the TPM securitymodule. 4The design of software system based on the hardware platform. Accordingto the requirements of the system to choose the appropriate bootloader,embedded operating system, add peripheral hardware device drivers, etc. Theapplication of the system program development mainly has: the writing of theserial port software and transplantation, the vehicle terminal graphic interfacedevelopment, etc. |
