摘要
采用电感数字转换器LDC1000为目标区域金属物体探测定位系统的探头,为感测系统的设计提供了低功耗、小封装、低成本的解决方案。设计的金属物体探测定位器基于STM32单片机为核心微控器,以LDC1000传感器为无线遥控小车的探头,通过扫描探测目标区域的金属物体,当LDC1000传感器在水平或者垂直距离检测、运动检测、金属成分检测(合金检测)到被测物体时,串行外设接口(SPI)将获取的检测信号传递给微控制器处理,通过外围的声光电路指示,定位金属物体的实际位置。该装置适用性强、检测技术稳定、性价比高,可以应用在汽车、消费电子、计算机、工业、通信和医疗领域。
The inductive digital senor LDC1000 was used as the probe in the metal object detection and locating system in the target area,and the design of the sensing system provided the low power consumption,small package and low cost solution. The metal object detection and locating system＇s MCU was based on STM32,and the wireless remote controlled car of the loading LDC1000 senor as probe was scanning and searching the target area for the metal objects. This scheme can be suitable for the horizontal or vertical distance detection,motion detection,metal component testing to measure object,and the Serial Peripheral Interface（ SPI）acquired the detection signal to the MCU processing. The actual position of the metal objects was available by the sound and light circuit. The system design of the device of wide applicability,stable detection technology and high cost performance,can be widely used in the automotive,consumer electronics,computer,industrial,communications and medical fields.
