摘要
介绍一种基于射频技术无线温度检测装置,主要由若干无线温度采集器和监控中心组成.无线温度采集系统,利用数字传感器DS18B20多点采集温度,通过射频收发器NRF905将数据发送到接收端,实现了对现场环境的不间断温度测量与监控,通过监控中心可以直观看到温度实时变化,做到足不出户即可了解各被测点的温度.此系统代替过去由人工来完成的温度数据采集,从而能有效的监控监测点的温度.该系统最大传送距离可达1000m;所采集的温度精度为0.5℃;稳定性强.具有多点采集,传输距离远,精准度高,使用方便,应用范围广等特点.
This article describes a RFID-based wireless temperature monitoring devices, which is mainly composed of several wireless temperature data acquisition and control center. The wireless temperature collecting system uses the digital collection temperature sensor DS18B20, sends the data to the receiver through the radio-frequency transceiver NRFg05, achieving the continuous temperature measurement and monitoring of the surrounding environment. From the control center, people can visually see the temperature changes in real time without having to understand the point of temperature. This system replaces the manual collection with the automatic collection of temperature data acquisition system and monitors the temperature, so as to effectively monitor the monitoring points of temperature. The maximum transmission distance of the system can reach up to 1000 m; the accuracy rate is of 0.5oC; and the stability is high. The system boasts the advantages of multi-point data acquisition, distant transmission, high precision, convenience, wide range of application and so on.
