An object coordinate intelligent detection system is designed based on the principle of single-chip microcomputer and ultrasonic ranging.The system is composed of an Arduino single-chip microcomputer,an ultrasonic module,a steering engine,and a display screen.The steering engine drives the ultrasonic module for rotation detection.Through the time difference generated during receiving and sending by the ultrasonic module and the rotation angle of the steering engine,the coordinate value of the object is calculated by polar coordinates.Thus,the coordinate detection of surrounding objects is completed.The system can realize the real-time detection and fast reading of object coordinates.
