Development Of Measurement & Control System Based On Single Chip Microcomputer For Automobile Component Test

There is needed a lot of detect and test in the auto parts design and production process, and so needed much modern special inspection and test equipment. And it is important practical significance and value to research and development for our country's automotive components of testing equipment by using computer of software and hardware technology, automation technology and mechatronics technology.Based on measurement&Control System for Automobile Component Testing,this paper proposed a model based on Upper and Lower detection tests,focusing on researching and developing the platform of the lower machine: measureing and control system of microcomputer . The main topics of this paper are as follows:â‘ Based on the analysis of the development of automotive components test system characteristics and the state of development at home and abroad.â‘¡Based on analysis of hardware structure of ARM microcontroller,develop and debug lower machine control system of ARM microcomputer,and it includes control module, data acquisition modules, human-machine interface module, the output control module, display module, communication module and other modules.â‘¢Research and analysis the method of communication from host computer to lower computer, focusing on analysis and researching USB communication protocol and method of communication.â‘£Analysis,design and debug lower computer software system based on the ARM computer.Finally, build and debug Upper and Lower Control platform with USB interface to the PC, and verify the correctness and feasibility of proposed programs, and provides a feasible foundation for the Commercial development.
