(上位机部分)
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 and Realization of Temperature Measurement System Based on Wireless Transmission Chip nRF905 (Host Part)
ABSTRACT
In the industrial production process, it needs strict requirements of standard and feasibility for the voltage, current, temperature, humidity, air pressure, etc. Various kinds of environmental parameters require real-time measurement and control.
Temperature is a very important physic, temperature control error could cause a production safety, product quality, product yield and so on a series of problems, so the significance of temperature testing is very many occasions cable transmission lines and wire transmission lines plex to transfer a valid data to the distance, so using wireless transmission in temperature measuring system can let temperature be collected and sent based on wireless chip and the distant operator can measure the real-time temperature changes.
This article mainly introduce the temperature measuring design and realization method based on temperature sensor DS18B20 and wireless transmission chip NRF905, the system is designed through the temperature measuring and wireless transmission controlled by t he single-chip is a wireless temperature measuring system using STC89C52RC puter as the control unit, the temperature sensor DS18B20 for temperature measuring devices ,wireless transmission chip nRF905 for the valid data wireless transmission and a digital t
