Based on the technology, the system is based on the control of AT89S51 SCM, using Dallas single line digital thermometer DS18B20, wireless receiving and sending module NRF24L01 to test and control the temperature data of a experiencing place. The whole system consists of the main system and subsystem. The main system pletes the functions of initializing and displaying the temperature value, displaying actual temperature, alarming when it is out of control, and receiving. The subsystem pletes the functions of receiving, and temperature collecting, controlling, and sending. The design concludes that this system has many advantages, such as its uniqueness, simple, convenience, and such mon using. It can be widely used in lots of industrial producing and controlling fields, applying this system can depart operators from execrable environment, realize producing automation, and improve corporation’s producing efficiency. Key words: AT89S51。整個系統(tǒng)包括主、從兩個子系統(tǒng),其中主系統(tǒng)完成對試驗現(xiàn)場設(shè)定溫度值、設(shè)定值顯示、實際值顯示、失控報警和接收數(shù)據(jù)功能;子系統(tǒng)完成溫度采集、溫度控制和發(fā)送數(shù)據(jù)功能。 編號: 202034140143 本科畢業(yè) 設(shè)計 基于單片機的 無線遠程溫度監(jiān)控系統(tǒng) 設(shè)計 系 院 : 信息工程學(xué)院 姓 名: 學(xué) 號: 0835140143 專 業(yè): 通信工程 年 級: 2020 級 指導(dǎo)教師: 職 稱: 副教授 完成日期: 2020 年 5 月 摘 要 II 本文論述的遠程溫度控制是將無線發(fā)射與接收和自動控制相結(jié)合的一種控制?;谶@種技術(shù),本系統(tǒng)以 AT89S51 系列單片機為控制單元,采用 Dallas單線數(shù)字溫度傳感器 DS18B20 和無線收發(fā)模塊 NRF24L01 對試驗現(xiàn)場溫度數(shù)據(jù)進行遠程無線測量與控制。該系統(tǒng)結(jié)構(gòu)簡單實用、功能齊全,通用性強,可被應(yīng)用于許多工業(yè)生產(chǎn)領(lǐng)域,它可使操作人員與惡劣的工作環(huán)境分離開來,實現(xiàn)生產(chǎn)自動化,提高企業(yè)的生產(chǎn)效率。 Temperature senior。 Display。從食品生產(chǎn)到化工生產(chǎn),從燃料生產(chǎn)到鋼鐵生產(chǎn)等等,無不涉及到對溫度的控制,可見,溫度控制在工 業(yè)生產(chǎn)中占據(jù)著非常重要的地位,而且隨著工業(yè)生產(chǎn)的現(xiàn)代化,對溫度控制的速度和精度也會越來越高。 遠程控制的通信方式有多種,如通過有線網(wǎng)絡(luò)、無線電等等。利用無線電通信,方便、靈活,而且
