文档介绍：基于nRF905的无线温度测量系统设计
摘要
在工业生产过程中,需要严格要求现场环境的标准性和可行性,对电压、电流、温度、湿度、气压等各种环境参数需要实时的测量以及控制。
温度是一个非常重要的物理量,温度控制失误就可能引起生产安全、产品质量、产品产量等一系列问题,因此对温度的检测的意义很重要。但是在很多场合有线传输排线复杂,无线传输是一种将有效数据传输至远方的一种有效方法,所以使用无线传输的测温系统可以对生产环境的温度进行无线采集并且能够使操作员可以远距离实时了解被测现场的温度变化情况。
本文主要介绍了基于温度传感器DS18B20和无线收发模块nRF905的无线温度采集系统下位机的设计和实现方法,本系统是通过单片机控制来实现对周围环境的温度进行测量和无线传输。它是以STC89C52RC单片机为控制单元,以温度传感器DS18B20为温度采集器件,以无线收发模块nRF905完成数据的无线传输,用数码管进行显示,实现温度的测量、无线传输、显示,就是一套通过无线方式实现温度的远程采集的完整系统。
本文详细论证了实现温度数据采集与无线传输方案的设计的总体架构,阐述了系统的硬件电路结构和完成各项功能相关的软件设计。

Design of Wireless Temperature Measurement System Based on Transmission Chip NRF905
ABSTRACT
In the industrial control field, people often need to collect a lot of field data, such as voltage, current, temperature, humidity, air pressure.
Temperature is a very important physical quantity, so temperature control failure could lead to a series of problems such as production safety, product quality, product yield and so on, so the meaning of the temperature detection keeps growing. Wireless transmission is an effective way to transfer the data far away, so people can apply the wireless transmission of high-precision temperature measurement system on the production environment for wireless transmission and operators can have access to the real-time temperature changes, thereby enhancing production efficiency.
The article mainly introduces design thinking as well as implementation methods based on the temperature sensor DS18B20 and wireless transceiver, and the system is controlled by STC89C52RC puter to achieve ambient temperature measurement and wireless transmission, the PC using visual programming techniques for remote monitoring. The system is based on the STC89C52RC puter, a temperature sensor DS18B20 for the detection device, a wireless transceiver module nRF905 pleting data’s wireless transmission, a LED tube for displaying, it can achieve the temperature measurement, wireless transmission and display.
