【摘要】：为提供一种新型的物体平面定位方法,设计一种操作简单、工程上容易实现的坐标定位仪。将超声波测距原理应用到物体的平面定位中,利用AT89S52单片机作为核心处理器,驱动两舵机进行旋转,带动两超声波测距模块US-100进行扇形扫描,分时发射超声波信号并采集反馈信号,计算测量距离,由RS-232串行口与计算机连接通信,将测量数据传输给主计算机,利用虚拟仪器LabVIEW,实时动态显示物体的坐标方位并绘制其移动路线。结果表明:单个超声波收发装置4 500mm以内测量误差在0~17mm之间,测量盲区为23mm。整个超声波定位仪样机各项功能完成良好。
[Abstract]:In order to provide a new method of object plane positioning, a coordinate locator is designed, which is simple in operation and easy to realize in engineering. The principle of ultrasonic ranging is applied to the plane positioning of objects. The AT89S52 single chip microcomputer is used as the core processor, the two steering machines are driven to rotate, the two ultrasonic ranging modules US-100 are driven to sector scan, the ultrasonic signals are sent out and the feedback signals are collected. The measurement distance is calculated and the RS-232 serial port is connected with the computer. The measurement data is transmitted to the main computer and the virtual instrument LabVIEW is used. The coordinate azimuth of the object is dynamically displayed in real time and its moving route is plotted. The results show that the measuring error of a single ultrasonic transceiver within 4 500 mm is between 0 and 17 mm. The blind area is 23 mm. the function of the ultrasonic locator prototype is good.
