摘要
系统以STC的90C52RC和12C5604AD单片机分别作为主控端与测距终端的控制器,通过超声波传感器实现距离的实时数据的测量。利用nRF24L01高速无线数据收发模块,实现数据的实时传送。系统包括主控端和测距终端两部分,主控端通过按键控制测距终端,并将实时数据显示在数码管上,同时,系统还具备距离设定功能,当测量数据到达设定值后进行声光报警提示。通过更换测量终端的传感器,系统可应用于工业数据采集、无线抄表、环境监测等领域。
A wireless distance measuring system based on 51 single-chip microcomputer is designed in this paper. Using 90C52RC and 12C5604AD from STC as the controllers of main control terminal and measuring terminal respectively and the ultrasonic sensor as detector , the system completes real-time distance measurement . The high speed wireless data transmission is achieved by making use of nRF24L01 .The system includes two parts -- main control terminal and measuring terminal. The main control terminal controls the measuring terminal through key-press, and displays the real-time data on nixie light. This system also has a distance setting function, by which the measured data exceeding the setting value can start up the acoustic-optic alarm. The system can be used in industrial data collection , wireless meter reading, environmental monitoring and other fields.
