为了实现对一定区域金属物体的探测及定位,本设计采用电感/数字转换器作为系统的探测模块,采用超低功耗单片机MSP430F149作为系统的微处理器。金属探测模块将检测信号及时传送到信号处理单元,在对采样信号运算处理的基础上,控制器准确控制小车自主行驶,实现对金属物体的搜索及准确定位,同时进行声光提示。
In order to achieve a certain area of the metal object detection and positioning, the design uses the inductor / digital converter as the detection module of the system, using ultra-low power microcontroller MSP430F149 as the system microprocessor. The metal detection module transmits the detection signal to the signal processing unit in time. Based on the operation of the sampled signal, the controller accurately controls the autonomous driving of the car and realizes the search and accurate positioning of the metal object, meanwhile, the sound and light are prompted.
