The invention discloses a pressure sensor for monitoring air pressure of a brake cylinder of a freight train, which comprises a metal screw head, a sensor module is arranged in the middle of one side of the metal screw head, a circular edge groove is formed in the non-circle-center position of one side of the metal screw head, and a plastic protective shell is arranged in the circular edge groove. A fool-proof clamping position is arranged at one end of one side of the metal screw head; through cooperation of the plastic package shell, the protective glue, the sealing layer, the ADC chip, the pressure DIE chip, the RFID chip, the pressure chip PCBA, the communication antenna, the sensor module PCBA and the grounding copper sheet, the vehicle brake cylinder is retransformed, the difficulty of maintaining the brake cylinder is effectively reduced, convenience is improved, the pressure sensor has a unique ID, and the pressure sensor is convenient to maintain. Vehicle number binding can be carried out through the handheld reader-writer or automatic vehicle number binding can be carried out through the intelligent management system, and then subsequent vehicle distinguishing is facilitated.

    本发明公开了一种用于货运火车车辆制动缸风压监测的压力传感器,包括金属螺头,所述金属螺头一侧的中间设有传感器模组,所述金属螺头一侧的非圆心位置处设有圆形边凹槽,所述圆形边凹槽的内部设有塑胶保护壳,所述金属螺头一侧的一端设有防呆卡位;本发明通过塑封壳、防护胶、密封层、ADC芯片、压力DIE芯片、RFID芯片、压力芯片PCBA、通讯天线、传感器模组PCBA和接地铜片的配合下,使得车辆制动缸进行再改造,有效的降低维护制动缸的难度,提高便利性,并且压力传感器有唯一的身份ID,可通过手持读写器进行车辆车号绑定或通过智能管理系统进行自动绑定车号,进而方便后续对车辆进行辨别。
