水溫遙測自控系統(tǒng)的設(shè)計(jì)

摘  要

 隨著信息技術(shù)的快速發(fā)展，在工業(yè)生產(chǎn)的各個(gè)行業(yè)，無線遙測控制系統(tǒng)的應(yīng)用已經(jīng)很普遍。與常規(guī)的控制系統(tǒng)相比它省去了中央控制設(shè)備與控制終端之間布線的麻煩、增強(qiáng)了系統(tǒng)的可移動(dòng)性。本系統(tǒng)的設(shè)計(jì)分為中央控制設(shè)備的設(shè)計(jì)、控制終端的設(shè)計(jì)及它們之間通訊的設(shè)計(jì)。在使用時(shí)，先通過中央控制設(shè)備的鍵盤輸入溫度的設(shè)定值，通過射頻方式將數(shù)據(jù)發(fā)送到控制終端，在終端收到溫度設(shè)定值后結(jié)合水溫的當(dāng)前值輸出控制量，達(dá)到遙測控制水溫的目的。本文主要探討了溫度采集設(shè)計(jì)、射頻通訊應(yīng)用的設(shè)計(jì)及在中央控制設(shè)備上的圖形界面和語音功能的設(shè)計(jì)。
 首先，簡單介紹了遙測控制系統(tǒng)的選題背景，全面總結(jié)了遙測控制的概念、特性以及設(shè)計(jì)思路等方面的問題。
 其次，介紹了水溫遙測控制系統(tǒng)的設(shè)計(jì)方法。本系統(tǒng)的設(shè)計(jì)共分為三個(gè)模塊：電源模塊、控制終端模塊和中央控制模塊。電源模塊為系統(tǒng)的工作提供直流穩(wěn)定電壓。控制終端模塊包括：溫度采集、射頻通信和控制量輸出等功能，其軟件的設(shè)計(jì)主要包括這些功能電路的驅(qū)動(dòng)及控制算法的實(shí)現(xiàn)。中央控制模塊包括：鍵盤、LCD顯示、語音和射頻通信等功能，它的軟件設(shè)計(jì)主要為圖形界面及語音功能的設(shè)計(jì)。
 接著，將整個(gè)系統(tǒng)進(jìn)行整合，從總體上實(shí)現(xiàn)設(shè)計(jì)要求中的各種功能。
 最后，對設(shè)計(jì)結(jié)果做了整體概述和分析。包括在設(shè)計(jì)初期元器件的選擇、設(shè)計(jì)中遇到的問題和完成設(shè)計(jì)后的個(gè)人體會(huì)等。

Abstract

With the rapid development of information technology, wireless remote control system has been very common in all sectors of industrial production. With conventional control systems, eliminating the need for central control of its equipment and control wiring between the terminals of the trouble, and enhance the system's mobility. The design of the system is divided into the central control equipment design, control of terminal design and the design of communication between them. In use, firstly input temperature settings through the keyboard of the central control module, through the RF data is sent to the control terminal, received the temperature settings, combine the current value to output volume to control the water temperature. This paper discusses the design of temperature collection, the design of RF communication applications and the designs of the graphical interface and voice features on the central control of equipment.
 First of all, a simple background briefing of the Remote control system is introduced, a comprehensive summary of the Remote controlling, features and design ideas, and other aspects.
 Secondly, the introduction of the temperature control system for the design of remote sensing methods. The design of the system is divided into three modules: power supply module, control module and the central terminal control module. Power supply module for the system to provide power. Control terminal blocks include: temperature collection, radio frequency communication and control output functions, the software includes these features of the drive circuit and control algorithm. Central control module including: a keyboard, LCD display, voice and radio communications and other functions, it’s mainly software is voice and graphical interface design.
 In succession, Integration of the entire system, from the overall design requirements to achieve various functions.
 Finally, the results do the overall design overview and analysis. This includes some of the problems encountered in the design, the choice of components and personal experience and so on.
Key words: Temperature telemetry control; RF Communications; DS18B20; Sunplus SPCE061A
