基于嵌入式的汽车状态远程实时监测系统
Vehicle condition real-time remote monitoring system based on embedded system
摘要
Abstract
A vehicle condition real⁃time remote monitoring system based on embedded system is studied in this paper. The embedded vehicle monitoring system and wireless data transmission system were investigated intensively. CAN bus is selected for communication of the vehicle⁃mounted embedded system,while GPRS communication is taken as the main communication means and Bluetooth communication as supplement for the wireless data transmission system. The OMAP⁃L137 processor pro⁃duced by TI is used to achieve data collection,transmission,human⁃computer interaction and other functions. The major sys⁃tems of the vehicle are monitored by multiple MSP430F169 processors,and the results are transmitted to the OMAP⁃L137 pro⁃cessor through the CAN bus. The Harvard H5 is taken as an example to test the performance of the embedded real⁃time remote monitoring system. The test result is compared with that got by the official automobile test instrument. The comparison results show that the test result got by the embedded vehicle condition remote monitoring system is basically consistent with the official test data(the error is not more than 5%),which can meet the basic requirements of remote monitoring and fault diagnosis.关键词
