The invention discloses a tire pressure acquisition method and system based on a Bluetooth wireless sensor network, and the method comprises the following steps: central equipment judges and filters monitored broadcast, obtains a wireless sensing terminal required by the central equipment, and sends the filtered data to production equipment related to an OBD-II interface through a reserved interface; after the needed wireless sensor terminal is obtained, the central equipment brings the wireless sensor terminal into a white list of the central equipment and then automatically disconnects after being electrified next time; and after connection and binding are completed, the central equipment periodically scans data of the wireless sensor terminal, obtains the numerical value of the tire pressure of the attribute table, and automatically receives notification data from the wireless sensor terminal at the time except periodic scanning. Based on the problem that wiring is needed in tire pressure detection, certain wire rods and manpower consumed in the production process are saved, and later vehicle maintenance is facilitated. Meanwhile, compared with wired communication or other wireless communication schemes, certain electric power resources are saved.
本发明公开了一种基于蓝牙无线传感器网络的胎压采集方法及系统,包括:中心设备对监听的广播进行判断和过滤,获取自身所需要的无线传感终端,并将过滤后的数据通过预留的接口发送到OBD‑II接口相关的生产设备;获取到需要的无线传感终端后,中心设备将无线传感器终端纳入本身的白名单之中下次上电之后自动的去连接;完成连接绑定后,中心设备周期性扫描无线传感器终端的数据,获取属性表的胎压的数值,周期性扫描之外时间自动接收来自于无线传感终端的通知数据。本发明基于胎压检测需要布线的问题,节省了一定的生产过程中所消耗的线材和人力,也有利于后期车辆的维护。同时,相对于有线通信或者其他无线通信方案节省了一定的电力资源。
