摘 要 随着工农业生产对温湿度的要求越来越高，准确测量温度变得至关重要。本文设计主要是针对恶劣环境下的工业现场以及高科技大范围的农业现场，布线困难，浪费资源，占用空间，可操作性差等问题做出的一个解决方案。该方案主要是利用热电偶采集外界的温度，利用无线传输实现在上位机显示采集到的温度，并对数据进行相应的对比和处理。 本文主要利用两路热电偶采集温度的模拟量，并且利用热电偶串行模数转换器实现信号放大、冷端补偿和A/D转换，再由单片机进行处理，并通过无线传输模块将测量的数值传输给PC机，在PC机上实现数据的对比，从而可以对工业现场和农业现场的环境温度进行实时监测，并且利用该设计还可以实现对热电偶测量准确度的现场检测。本设计结构简单，但应用范围广泛，使用方便，而且节约资源，同时可以进行远距离的监控。 关键词：温度数据采集，无线传输，热电偶，单片机，PC机 Abstract With the more and more request of industry and agriculture production in the temperature, it become very important to survey the temperature accurately. This article is designed for harsh environments and high-tech industries at the scene of large-scale agriculture at the scene, wiring problems, waste of resources, space, and make operational a poor solution. This design is mainly to use the thermocouple to gather temperature, and then use the wireless transmission to reveal the gathered temperature on the position machine, and comparison of data and processing the corresponding. This design mainly uses two thermocouple to gather the analog quantity of the temperature and uses the thermocouple serial ADC to achieve signal amplification, cold junction compensation and the A / D conversion, and then the digital quantity will be able to be distinguished by the microchip and then transmitted through the wireless transmission module to the PC, and to achieve the compare of data, then the temperature of the scene of industrial and agricultural can be monitored in any time, and through this design we can detect the accuracy of thermocouple at the scene of measurements. This system is of simple structure, but in extensive application range, easy being used. Moreover, it saves resources and also, the long range monitor may be carried on at the same time. Key words: temperature data acquisition, wireless transmission, thermocouple, single-chip, PC 目 录 摘 要 I Abstract II 目 录 III 第一章 引 言 1 1.1 课题的背景和意义 1 1.2 无线温度采集原理 2 1.3无线温度采集的发展状况 4 1.4无线温度采集系统的研究内容 6 第二章 总体方案设计 7 2.1任务要求 7
