摘 要
在现代的生活环境下，温度扮演着越来越重要的角。无论你的生活、学习、工作的状况怎么样，温度都无时无刻的伴随着你。温度监控在工业生产中奶报箱占有非常重要的地位,并与工业生产的现代化有着密切关系。温度控制的速度和精度随着社会的的发展也会不断增高。近年来,温度监控领域发生了巨大的变化,工业生产的控制不再局限于温度的近距离传输或直接控制,需要远程控制,这就产生了无线温度监控。 本文论述的无线温度控制是将无线发送与接收和自动控制相结合的一种监控。基于这种技术，本系统以AT89C51系列单片机为主控制单元，采用Dallas单线数字温度传感器DS18B20和无线收发模块NRF24L01对试验现场温度数据进行无线传输。整个系统包括主控制系统，其中主系统完成发送机对试验现场温度采集、单片机处理和无线传输模块调制传输；接收机完成温度接受数据功能以及数码管显示温度测量值功能。
通过接收机USB数据线接入上位机，上位机可以接收到接收机传来的数据，从而上位机监控系统可以显示发送机采集的温度以及一段时间内的温度曲线。该系统结构简单实用、造价成本低、功能齐全，通用性较强，占用体积小，可被应用于许多气象部门、工业生产和现代农业生产领域，它可使操作人员与恶劣的工作环境分离开来，实现生产自动化，提高企业的生产效率。

光电感应器ABSTRACT
Under the modern living environment, the temperature plays a more and more important role. No matter how's your life, study, work condition, temperature all the time with you. Temperature monitoring occupies very important position in industrial production, and has close relationship with the modernization of industrial production. Temperature control of the speed and accuracy with the development of the society will also be increasing. In recent years, there have been great changes in temperature monitoring areas, industrial production control is no longer limited to the temperature of the close distance transmission or direct control, need to remote control, this creates a wireless temperature monitoring.
This paper discusses wireless temperature control is combining the wireless sending and receiving and automatic control of a monitoring and control. Based on this technique, this
涉水喉system is given priority to with AT89C51 series single-chip microcomputer control unit, the Dallas single line digital temperature sensor DS18B20 and wireless transceiver module NRF24L01 temperature data for wireless transmission of test on the spot. The whole system including the main control system, including the main system to complete the transmitter to test the temperature acquisition, single chip processing and wireless transmission module modulation transmission; Receiver complete accept data function and the digital tube display temperature measurement function.
By receiver USB cable connected to the PC, PC can receive data from the receiver, and PC monitoring system can display the transmitter collection of temperature and temperature curve of a period of time. The system structure is simple and practical, low cost, complete function, strong commonality, being a small volume, can be used in many of the meteorological department, industrial production and modern agricultural production areas, it can make the operator and the separation of poor working environment, realize the production automation, improve the production efficiency of enterprises.
