本设计是以TI公司的MSP430G2553和LDC1000芯片为核心设计的一个金属物体探测定位器。采用MSP430G2553单片机作为系统控制处理器，LDC1000电感/数字转换器评估板作为金属物体探头对硬币及铁环进行探测，当检测到硬币或铁环时单片机通过反馈信息控制小车不动而实现定位。同时，运用PWM直流电机调速技术，完成对小车运动速度和运动方向的控制，并用蜂鸣器和发光二极管进行声-光显示是否探测到硬币或铁环。整机使用单电源同时对电机部分、芯片部分、显示部分进行供电。-The design is based on MSP430G2553  and LDC1000  chip of TI company  as the  probe  positioner of a metal object  core design. Using MSP430G2553 singlechip  as the system control processor,LDC1000 inductor  / digital converter 　uation board as  metal objects  on  the coins and  ring  detection  probe. When detecting the  coins or  ring  when the  singlechipr through the feedback  information to control the car  does not move and  position. At the same time,  the use of PWM  DC motor speed control  technology,complete  control of the car  speed and direction of motion,  and  sound and  light whether the  detected  coins or  ring  buzzer  and light-emitting diodes.　The  use of  single supply  at the same time,  the electrical part,  the chip  part and a display part  for power supply.
