The Research And Application Of The Braking Valve Testing System In Vehicle

Nowadays, with constant innovations in technology and rapid development, whether in industry or in other areas, people have a higher demand in embedded system performance; they require not only to deal with high speed, high precision large amounts of data , but also require equipment more integration, more interaction and friendly human-machine interfaces. Traditional 8 to 16 bit monolithic integrated circuits are limited in slow operating speed and small storage capacity, so it is hard to better meet the information industry development. As a 32-bit embedded microprocessor ARM are better solution of these bottlenecks than monolithic integrated circuits, but DSP microprocessor whose real-time execution speed is tens of millions of the complex instructions per second.The thesis introduces the brake system based on the ARM processor and DSP processor pair of the data detection system. At the same time, with the green energy and environmental protection of solar energy provide electricity supply for the system. In hardware, the system is to use S3C2440 and TMS320C6713 as the core, on this basis to extend the UART RS485, USB interfaces, and to adapt to different circumstances of the data exchange. The system provides the LCD touch screen module and keyboard module, with good man-machine interaction. In the software, it is based on Linux cross development environment to achieve Linux operating system BootLoader porting and through DSP processors communicate with interaction realize the automotive solenoid valve in the spectral analysis and test.In this paper, automobile brake for the detection of objects is designed based on ARM processor and DSP processors of the data detection system. Meanwhile, green energy, green energy solar energy provides power supply system for the system. On the hardware side, the system centering S3C2440 and the DSP TMS320C6713, extends the UART, RS485, USB interface to adapt to different environments for data exchange. At the same time, system which provides the LCD touch screen display and keyboard input module, input module has a good human-computer interaction function. On the software side, the system depend on Linux cross-development environment for Linux-based operating system to achieve Bootloader transplant, and through DSP processors communicate with interaction realize the automotive solenoid valve in the spectral analysis and test.This system can better meet the automotive brake manufacturing enterprises in the product quality check and data analysis for the enterprise, and provide a strong guarantee that increase productivity and improve product quality.
