针对现有疼痛检测设备体积笨重，不便于携带的局限性，设计了一种基于STM32的便携式高精度压力测痛仪。用高精度的压力传感器为主体的测压触头拾取压力痛信号。通过对放大电路和滤波电路等信号预处理，有效地滤除系统噪声。TFT-LCD实时显示被测的压力值，有效建立被测对象的压痛阈值。用USB接口将所得数据传输到PC机上存储，便于后续医生对疾病的诊断与治疗。

In accordance with the bulky volume and not easy to carry of pain detection equipment limitations, designs a kind of portable high-precision dolorimeter based on STM32. Using the high precision pressure sensor pressure contact as the main body to make the pressure pain signals. Through the signal preprocess of the amplifying circuit and thefilter circuit, to eliminate the system noise effectively. Use the TFT-LCD to display the real-time measured pressure value, and establish a pressure pain threshold of the object. The USB interface transmits the data to PC to store, and it’s beneficial to the diagnosis and treatment of subsequent.
