摘　　要：为了实现对移动目标位置信息的测量,基于基站定位和GPS定位的不同需求,采用MC20全功能通信定位芯片及STM32微处理器,设计了一个多种定位方式的定位终端,该定位终端能够对移动目标进行实时定位检测,在不同情况下选择适合的定位方式,在室外或者GPS信号较为良好的情况下采用GPS定位,在室内或者GPS信号较弱的情况下采用基站定位,从而保证将检测目标所在位置的定位信息实时准确上传及显示。通过对定位终端的GPS定位及基站定位测试,GPS定位误差小于10m,基站定位误差小于200m,可应用于市区范围内的设备定位。In order to realize the measurement of moving target position information,based on the different needs of base station positioning and GPS positioning,using MC20 fully functional communication chip positioning and STM32 microprocessors,designed a variety of positioning terminal positioning way,the positioning terminal can be real-time positioning for moving target detection,under different circumstances to choose suitable way of positioning,use GPS positioning outdoors or when the GPS signal is relatively good,use GPS positioning outdoors or when the GPS signal is relatively good,and use GPS positioning indoors or when the GPS signal is relatively good.Under weak conditions,base station positioning is used to ensure that the positioning information of the detected target location is accurately uploaded and displayed in real time.Through the GPS positioning of the positioning terminal and the base station positioning test,the GPS positioning error is less than 10 m,and the base station positioning error is less than 200 m,which can be applied to equipment positioning in the urban area.
