摘 要: OBD(On-Board Diagnostics)意为"汽车自诊断系统",它可实现对汽车发动机、燃油系统、离合器等部件的监测。OBD系统提供对外的接口和公开协议,可与其他设备实现数据通信。利用S3C2440嵌入式开发板来采集OBD接口对危险驾驶有判断依据的数据,并对数据进行融合分析,一旦出现危险情况,则通过外置扬声器来实现对驾驶员的语音报警,从而避免事故的发生。系统还提供SD卡接口,可将报警信息存入到SD卡中,方便数据后期的分析处理。 On-board diagnostics (OBD) can monitor the engine, fuel system, clutch and other devices of the car. OBD provides the external interfaces and open protocols, it can achieve data communications with other devices. This system collects OBD interface data which can be the evidence of dangerous driving by S3C2440 embedded development board. The system analyses the data and alarm the driver when dangerous driving emerge so that accidents can be avoided. This system provides SD card interface, it can record the dangerous driving data in the SD card to be processed and storaged.
