基于单片机的无线温度发送和接受系统的设计.doc

摘 要 温度是人们日常生活中接触非常多的一个物理量，人类的日常生活、动植物的生存繁衍跟周围环境的温度密切相关，石油、化工、冶金、纺织、机械制造、航空航天、制药、烟草、档案保管、粮食存储等领域对温度也有着较高的要求，由此可见，在工农业领域和日常生活中，温度是最常用的被控参数之一。因此，对温度的监测已成为生产过程中极其重要的技术要求。由于一些大型场所的测量空间较大，维护较困难，现有的有线温度测量系统无法满足计量检测的需要。为了能够实现对远距离温度数据的计量采集，需要设计一种智能无线温度数据采集系统。 本文介绍的是一个由单片机构成的无线温度控制系统，它利用STC89C51单片机、DS18B20、nRF903及等其他器件实现。工作原理是单片机利用DS18B20对温度进行实时采集，然后把温度数据通过nRF903射频模块进行无线发送，接收端收到信号后，进行解码，之后实现温度显示。本设计结合嵌入式技术和无线传感器技术的无线温度采集系统，系统具有高性能、低功耗的特点，以及快速处理数据的能力，能够实现对远距离温度数据的计量采集。本文对硬件和软件进行了框图设计，protel原理图设计，程序框图设计，源程序设计 关键词：嵌入式；无线发送接收；温度测量 ABSTRACT Temperature is a common physical in daily life. Temperature is related to people’s and animals’ daily life. It is sensitive in temperature in some area, like Petroleum, chemical, metallurgy, textile, machinery manufacturing, aerospace, pharmaceutical, tobacco, file storage and food storage. Therefore, it is important to measure the temperature accurately. Due to some places is too large to measure the temperature with today’s technology, we need design wireless system to solve this problem. What this text introduction is a constitutes to from the single slice machine of wireless temperature control system, it make use of STC89C51 single slice machine and other spare part realizations such as the DS18B20，nRF903 and etc.. Temperatures measuring work principle is a single slice machine to make use of the DS18B20 rightness temperatures to carry on collect, then carry on a wireless to send out with the nRF903, carry on a decoding after receiving to carry to receive signal, after carry out a temperature manifestation. This design combines embedded technology with wireless temperature collecting system, the system is high performance and low power consumption. It calculates fast, and can measure long distance temperature. This text carried on frame diagram a design to the hardware and the software, the protel principle diagram design, procedure frame the diagram design, source program design, text after appendix complete source procedure.
