【摘要】：為提供一種新型的物體平面定位方法,設(shè)計(jì)一種操作簡單、工程上容易實(shí)現(xiàn)的坐標(biāo)定位儀。將超聲波測距原理應(yīng)用到物體的平面定位中,利用AT89S52單片機(jī)作為核心處理器,驅(qū)動兩舵機(jī)進(jìn)行旋轉(zhuǎn),帶動兩超聲波測距模塊US-100進(jìn)行扇形掃描,分時(shí)發(fā)射超聲波信號并采集反饋信號,計(jì)算測量距離,由RS-232串行口與計(jì)算機(jī)連接通信,將測量數(shù)據(jù)傳輸給主計(jì)算機(jī),利用虛擬儀器LabVIEW,實(shí)時(shí)動態(tài)顯示物體的坐標(biāo)方位并繪制其移動路線。結(jié)果表明:單個(gè)超聲波收發(fā)裝置4 500mm以內(nèi)測量誤差在0~17mm之間,測量盲區(qū)為23mm。整個(gè)超聲波定位儀樣機(jī)各項(xiàng)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.
