The invention discloses a digital sensor of a high-speed rail brake system, which comprises an elastic body, eight strain units, a flexible PCB (Printed Circuit Board), two cable assemblies and a digital amplifier, and is characterized in that the elastic body is of a hollow cylindrical structure, and an annular groove is formed in the upper end surface of the elastic body; the eight strain units form two Wheatstone measuring circuits, the strain units, the flexible PCB and the digital amplifier are packaged in the annular groove through silica gel, the output ends of the two Wheatstone measuring circuits are electrically connected with the input end of the flexible PCB, and the output end of the flexible PCB is electrically connected with the input end of the digital amplifier. The device is used for being integrated on a brake actuator to measure the applied braking force, independent double output is achieved through the two mutually independent Wheatstone measuring circuits, the two paths of output signals are the same, the braking force applied in a brake system can be monitored and fed back in real time, and mutual monitoring can be achieved.

    本发明公开了一种高铁刹车系统的数字传感器,包括弹性体、8个应变单元、柔性PCB电路板、2个电缆组件、数字放大器,弹性体为中空圆柱形结构,弹性体的上端面上设有环形凹槽;8个应变单元构成2个惠斯通测量电路,应变单元、柔性PCB电路板、数字放大器通过硅胶封装设置于环形凹槽内,2个惠斯通测量电路的输出端与柔性PCB电路板的输入端电连接,柔性PCB电路板的输出端与数字放大器的输入端电连接。本发明用于集成到制动执行器上以测量所施加的制动力,通过2个相互独立的惠斯通测量电路,实现独立双输出,且两路输出信号一样,既可以实时监测反馈制动系统中施加的制动力,又可实现相互监测。
