摘　　要：文章采用单片机并联合GPS定位模块研发了一款地理位置显示系统,应用Altium Designer软件对硬件进行设计,解决了SIM808模块、STC89C52单片机芯片和LCD显示器之间串口通信问题,并且利用仿真器对单片机存储区进行数据搜索,采用串口中断和时延函数计算GPS模块收到的数据,将其处理成所在城市后送显。测试表明,该系统能在液晶屏上正确显示信息。This paper uses the single-chip microcomputer in parallel with the GPS positioning module to develop a geographic location display system.The Altium Designer software is used to design the hardware,which solves the problem of serial communication between the SIM808 module,the STC89C52 single-chip microcomputer chip and the LCD display.Data search is carried out in the storage area of the single-chip microcomputer,and the serial port interrupt and delay function are used to calculate the data received by the GPS module,and it is processed into the city where it is located and then sent to the display.Tests show that the system can be displayed correctly on the LCD screen.
