34、1.1 选题的目的和意义温度是工业生产中常见的被控参数之一。从食品生产到化工生产，从燃料生产到钢铁生产等等，无不涉及到对温度的控制，可见，温度控制在工业生产中占据着非常重要的地位，而且随着工业生产的现代化，对温度控制的速度和精度也会越来越高。近年来，温度控制领域发生了很大的变化，工业生产中对温度的控制不再局限于近距离或者直接的控制，而是需要进行远距离的控制，这就产生了远程温度控制。远程控制的通信方式有多种，如通过有线网络、无线电等等。每一种方式都有其优点和缺点。利用无线电通信，方便、灵活，而且经济。它不需要像有线网络控制耗费巨大的通信资源，也不受网络速度的影响。在温度控制的方法上，传统的控制方

35、法(包括经典控制和现代控制在处理具有非线形或不精确特性的被控对象时十分困难。而温度系统为大滞后系统，较大的纯滞后可引起系统不稳定。在温度采集方法上，通常是利用热电偶把热化为电信号，再通过A/D 转换得到温度值。这种方法速度慢，而且精度不是很高。综合上面的考虑，本次毕业设计设计了基于无线电通信的远程温度控制系统。现代工业设计、工程建设及日常生活中常常需要用到温度控制，早期温度控制主要应用于工厂中，例如钢铁的水溶温度，不同等级的钢铁要通过不同温度的铁水来实现，这样就可能有效的利用温度控制来掌握所需要的产品了。在现代社会中，温度控制不仅应用在工厂生产方面，其作用也体现到了各个方面，随着人们生活质量的

36、提高，酒店厂房及家庭生活中都会见到温度控制的影子，温度控制将更好的服务于社会。近年来，单片机发展十分迅速，一个以微机应用为主的新技术革命浪潮正在蓬勃发展，单片机已经渗透到工业、农业、国防，科研以及日常生活等各个领域。传统的温度采集的方法不仅费时，而且精度差满足不了各行业对于温度数据提高精度，设备高可靠性的需求。单片机的出现使得温度数据的采集和处理得到了很好的解决。选择适当的单片机和温度传感器以及前端处理电路，可以获得较高的测量精度，不但方便快捷，成本低廉，省事省力，而且大幅度提高了测量精度。文档编码:CF10J9V9W3Z4 HR2H5X3V7G1 ZJ2K3Q8N9L8文档编码:CF10J9
