Vehicle Detection System With The Design Of Mobile Devices

In this paper, In order to solve the car with the mobile device testing cycle is long, low accuracy, can not be dynamic testing and other issues, Designed a detection system based on PC104. The system is based on PC104 board as the core, Through the power conversion board, driver board, A/D acquisition card, I/O interface board real-time collection voltage signal, switching signal, pulse signal, PWM signal, While the test results, save, print.The article first detailed description of the PC104 board and the basic knowledge of detection, Focused on how to build an embedded data acquisition system and dedicated data acquisition module (PM516 and PM549). Based on the data bus of the basic theory and knowledge of microprocessor performance and the advantages and disadvantages, Designed based on PC104 bus data acquisition system. Finally, discusses how the application of dynamic data acquisition and fault location.Hardware design includes power to take a model, I/O driver board, data acquisition module, the selection of the embedded system board. PC104 bus architecture based on design ideas, In terms of software, modular programming, application programming VC++6.0. Software system with intelligent data collection, data analysis, system self-test, document management, and fault location functions.Complete the dynamic test of the system, fault location, save and print test results, Effective solution to the maintenance of existing in slow, long cycle and low accuracy problem, The test system is reliable, stable and can run a long time.
