The invention discloses an external TPMS (Tire Pressure Monitor System) sensor for a heavy truck, which comprises a helical antenna and a 1225 battery and is arranged outside an automobile tire; by improving the communication rate of the TPMS sensor, and/or reducing the sampling period, and/or reducing the number of transmitted data frames, and/or reducing the radio frequency output power, the system power consumption is reduced; and/or an LNA circuit is added in front of the input end of the corresponding receiver antenna. By reducing the power consumption of the system, the requirement of long service life of the TPMS sensor is met; a helical antenna is adopted, a matching network is configured, and a 5dBm chip is adopted to output power, so that the miniaturization of the TPMS sensor is realized; compared with a traditional TPMS sensor, the diameter of the adopted battery with the size of 1225 is reduced by about 8 mm, the weight is reduced by more than 1/3, and miniaturization of the TPMS sensor is further achieved.
本申请公开了一种用于重型卡车的外置式TPMS传感器,所述TPMS传感器包括螺旋天线和1225电池,安装于汽车轮胎外;通过提高TPMS传感器的通讯速率,和/或降低采样周期,和/或降低发射数据帧数,和/或降低射频输出功率,从而降低系统功耗;和/或在相应的接收器天线输入端前置增加LNA电路。本申请通过降低系统功耗,满足TPMS传感器长寿命的需求;采用螺旋天线,配置匹配网络,采用5dBm芯片输出功率,实现TPMS传感器的小型化;采用的1225尺寸电池,相对于传统TPMS传感器来说,其直径减少约8mm左右,重量降低1/3以上,进一步实现了TPMS传感器的小型化。
