一种基于安卓蓝牙和OBD接口的车辆监测与控制方法

A Method to Monitor Vehicles Based on Android System by OBD Interface and Bluetooth Technic

文章提出了一种方便快捷可靠的车辆或产品监测控制方法,此方法是由直插在车辆上的OBD接口的下位机来采集车辆或产品发送的相应CAN信息,并通过蓝牙通信方式来跟上位机即安卓移动终端进行信息交互,从而实现对车辆或产品的实时监测与控制的目的。此方法具有成本低、方便快捷、对技术人员的要求低、可靠性高等显著特点,并且硬件方案可拓展性很强,只需修改相关软件即可实现对车辆或者产品的其他操作,例如标定、诊断等等。

A convenient and simple method to monitor vehicles is designed on android system. It contains two parts, one is upper monitor block and another is lower block. Upper monitor block is a mobile machine developed on android system. The lower block connects to the OBD interface of vehicles to collect the information of vehicles by CAN message. The lower block exchanges messages with the upper monitor block by Bluetooth. This way has a lot of benefits, such as： the lower cost, more convenient, less special technical requirements to workers, higher reliability and stronger extending characteristic. You can only change the software to realize other functions using the same hardware case, such as： calibration, diagnoses and so on.
