摘要
目前出现的温度检测仪器一般是单点测量、报警监控,对于需要多点测量、实时监测的情况,存在着温度信息传递不及时、精度不高的缺点。本文设计完成了基于2.4G无线收发芯片nRF24E1和数字温度传感器DS18B20组成的从机模块,结合上位机软件,构成了温度遥测系统,不仅能实现点对点和一点对多点的无线通信,而且能完成从机的高温报警和电池电压的监测。由于本系统均采用数字技术,所以性能稳定、实时性强、分辨力高,具有较强的实用意义。
The temperature detecting instruments in the market usually are single point measuring and alarm watching. For the instance of multipoint measuring and real-time watching, the temperature information can＇t be transferred in time and the precision is low. In this paper, the design of a slave module based on the 2. 4 GHz radio transceiver nRF24E1 and the digital thermometer DS18B20 is introduced. Linking to the upper computer＇s software, the module makes up of a temperature telemetry system. The system has the functions of point-to-point and point-to-multipoint communication. It can also alarm when the slave＇s temperature is too high, or the voltage is too low. Owing to digital technique being adopted, the system has stable performance, strong real time character, high resolving power, and some great practical significance.
