The invention discloses a tire pressure monitoring device and a tire pressure monitoring system. The tire pressure monitoring device comprises a microprocessor, a timer, an electricity storage device and a plurality of sensors, the sensors further comprise a pressure sensor for collecting the tire pressure, an acceleration sensor for collecting the tire acceleration and a temperature sensor for collecting the tire temperature. The microprocessor is provided with at least three different vehicle condition modes, and in each vehicle condition mode, the started sensors are not completely the same, the data acquisition frequencies of the sensors are not completely the same, and the executed alarm detection is not completely the same. And when the alarm detection result is true, triggering to execute a corresponding alarm mode, and sending an alarm data packet in different broadcast modes through BLE Bluetooth broadcast. According to the system, the microprocessor and various sensors are integrated, so that the tire state is comprehensively monitored. According to a vehicle condition mode, tire data are collected at different frequencies, alarm detection is executed, and an alarm is given out through BLE under an abnormal condition, so that electric power is effectively saved, and the service time of the tire pressure monitoring device is prolonged.

    一种胎压监测装置及胎压监测系统,其中的胎压监测装置包括微处理器、计时器、储电装置及多个传感器。传感器还包括采集轮胎胎压的压力传感器、采集轮胎加速度的加速度传感器、采集轮胎胎温的温度传感器。微处理器设置有至少三种不同的车况模式,在各车况模式下,启用的传感器不完全相同、传感器的采集数据频次不完全相同、执行的报警检测不完全相同。当报警检测的结果为真时,触发执行相应的报警模式,通过BLE蓝牙广播以不同的广播模式发送警告数据包。本申请通过集成微处理器与多种传感器,实现车胎状态全面监测。根据车况模式,以不同频次采集车胎数据、执行报警检测,在异常情况下才通过BLE发出警报,有效节省电力,延长胎压监测装置的使用时间。
