摘 要

 本說明文重點講述的是實驗室的綜合布局與設計，本次畢業(yè)設計的目的是以我院電子工藝實習的需要為目標，設計并制作相應的配套裝置。
 通過本題目的研究和制作。首先，是對今后其它電力電子安裝調試場所的配置、安全檢測及布線奠定一定的工作基礎。其次是讓學生掌握安全檢測及布線的設計計算及方法。再就是對學生自學習能力、綜合運用所學理論知識和技能的一種綜合性工程實踐鍛煉，從而培養(yǎng)學生的創(chuàng)造能力、獨立工作能力和提高學生分析、解決實際問題的能力。
 設計主要以501實驗室為目標的布局設計。按電子工藝實習的要求設計電子工藝綜合實訓臺；電源布線及開關選用的設計；電烙鐵的溫度檢測及自動控制裝置設計；儀器、儀表及工具的配置和布局設計；安全指示及通風等設施的配備設計。
 控制電路利用電阻電橋實現(xiàn)的高精度溫度控制電路，采用繼電方式，可以將溫度控制在±50℃范圍之內，從而實現(xiàn)動態(tài)的溫度調節(jié)。電阻電橋，運算放大器，功率放大，鉑電阻，開關電源。其工作原理是由熱電阻將溫度信號變換成電壓信號經(jīng)過放大器放大后與設定的電壓值比較，超過其電壓值將在放大器輸出端產生電流驅動三極管工作，進而使繼電器工作達到控制電源回路的功能。

  
 
關鍵詞：Pt100鉑熱電阻；直流穩(wěn)壓電源；運算放大器；放大器；三級管。

Comprehensive solid design and the manufacture of the room of the electronics craft

Abstract

 This comprehensive layout and designs that explains what the text point relate to is a laboratory, the purpose of this graduation design is a demand that practices with the electronics craft of my hospital for the target, the design combines the kit device that manufacture correspond.
 Pass the subject purpose research and creations.First, install to adjust to try the amenity to install to other electric powers of aftertime electronics, the safety examine and the cloth line lay the certain work foundation.It is design calculation and methods that lets the student control the safety examination and cloth line the next in order.Again be the creation ability to the student from the study the ability, comprehensively the usage talk about the knowledge and technical ability a kind of the academic theories comprehensively sex engineering the fulfillment the ，thus train the student, independent work ability and raise the student analysis, resolve the actual problem of ability.
 Design main with 501 laboratories for target of layout design.Press the request design  electronics craft of the electronics craft practice the comprehensive solid set of ，The power supply cloth line and switches choose the design for use;Give or get an electric shock the temperature of the hot irons examination and automatic controls device design;The instrument, appearance and tools install and set up the design;The equipment design of the safety facilitieses such as designation and airiness etc..
 Control the high accuracy  temperature control electric circuit that the electric circuit makes use of the electric resistance electricity  bridge realization, adopt after the electricity method, can control temperature in 50 scopes of ℃ of ± inside, thus carry out the temperature of the dynamic state to regulate.The electric resistance gives or get an electric shock the bridge, the operation enlarger, the power enlarge, the platinum electric resistance, switch power supply.It work the principle exceed after the temperature signal transformation become the electric voltage signal to enlarge through enlarger with enactment of the electric voltage value comparison, from the hot electric resistance its electric voltage value will output to carry to produce the electric current to drive the triode transistor work in the enlarger, then making after the function that the electric appliances work to attain to control the power supply back track.

Keyword:Hot electric resistance of Pt100 platinum;The direct current is steady to press the power supply;Operate the enlarger;Enlarger;X-rated tube.
