【摘要】 为了提高车辆行驶的主动安全性,降低交通事故的发生,提出了一种基于无线网络技术的车辆信息监视方法,设计并实现了车辆信息实时监视系统。该监视系统采用自行设计的多元数据交互协议与摄像头、OBD(车载自动诊断系统)信息采集模块、加速度传感器、GPS等通信,实现了对车周视频、ECU(电子控制单元)故障信息、行驶信息和位置信息的实时监视。实验结果表明,该监视系统监视效果好,实时性强。更多还原

【Abstract】 To improve the active safety of drive, reduce the traffic accidents, a vehicle information real-time monitoring system based on wireless network technologies is proposed and implemented. In the monitoring system, a multiple data exchange protocol is designed to communicate with wireless camera, OBD information acquisition module, acceleration sensor and GPS. The system can monitor the video information around vehicles, malfunction of ECU, running information and the location information of vehicles. Experiments showed that this monitoring system is effective and real-time.更多还原
