摘　　要：为克服操纵杆接触式角度传感器带来的机械磨损从而影响输出特性的缺陷,采用TDK-Micronas公司最新款的磁传感器编程器TDK MSP V1.0为软件开发平台,以HAL 3725霍尔芯片设计出一种非接触式角度霍尔传感器。通过对传感器芯片的选型,传感器模型与标定实验平台的搭建,硬件电路的设计以及编程器对传感器标定的软件流程控制,最终经过实验测试采集出传感器数字信号。实验结果表明:与接触式传感器相比信号波动小,更加灵敏,减少机械磨损,从而实现非接触式角度传感器的设计。In order to deal with the defects of mechanical wear caused by the joystick contact angle sensor,which affects the output characteristics,in this article,by using the latest magnetic sensor programmer TDK MSP V1.0 developed by TDK-Micronas as the software development platform,a non-contact angle Hall sensor based on HAL 3725 Hall chip is designed.Through the selection of the sensor chip,the construction of the sensor model and the calibration experiment platform,the design of the hardware circuit and the software process control of the sensor calibration by the programmer,the digital signal of the sensor is finally collected through the experimental test.The experimental results show that compared with the contact sensor,the signal fluctuation is smaller,more sensitive,and the mechanical wear is reduced,which leads to the design of the non-contact angle sensor.
