在以STM32F103单片机为控制核心、LDC1314电感数字转换器为探头的金属探测系统基础上,为了进一步提高探测系统的灵敏度,通过改变LDC1314前端电感线圈的圈数、线宽及外直径等参数,采用控制变量法进行实验。测试结果表明:最终确定了一组相对最优的线圈几何参数,实现了系统灵敏度的提升。

A metal detecting system is designed based on STM32F103 microcontroller unit（MCU） and LDC1314 inductance to digital converter. To further improve the sensitivity of the detecting system, a method is proposed by changing the inductance coil numbers in the front of the LDC1314, the width and the outer diameter of the coil. The experiment is carried out by control variable method and a sensitivity improving method is proposed. The test results show that the method determines relative the optimal geometric...
