基于NRF905的无线测温系统设计摘 要在工业生产过程中，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，施工困难，而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NRF905的无线测温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，最后用数码管进行动态显示，从而实现温度的测量、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显示的完整系统。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，阐述了系统的总体硬件电路结构和完成各项功能相关的软件设计。关键词：STC89C52RC，NRF905，温度采集，无线传输ABSTRACTIn the industrial production process, temperature is a very important physical quantity. The control failures of temperature may lead to a series of problems in production security, quality of products, product output and etc. Therefore, temperature detection is very important. But in many occasions, cable transmission is complicated and wireless transmission is an effective way to transfer the efficient data to distant place, so the use of temperature measurement of wireless transmission system can collect the temperature of the production environment wirelessly. Therefore, it enables the operator to know the temperature changes real- time in the distant.This paper introduces the design of wireless temperature measuring system, which based on NRF905 chip. The system is controlled by single-chip microcomputer to achieve temperature signal processing and wireless transmission.
