摘 要
隨著當(dāng)代科學(xué)技術(shù)的迅速發(fā)展，各種電器、電子設(shè)備全面進(jìn)入社會生活各個領(lǐng)域，成為社會文明進(jìn)步的重要標(biāo)志。在我國，人民生活水平不斷提高，對家用電器的需求量越來越大。各類電器、電子設(shè)備在全國城鄉(xiāng)和到迅速普及，給生產(chǎn)帶來極大方便。但各類電器、電子設(shè)備的廣泛使用，由此帶來的人身事故也大為增加。給生命財(cái)產(chǎn)帶來危害，觸電傷亡和電氣火災(zāi)是常見例子。因此，電器、電子設(shè)備的使用安全性這一重要問題，成為決定產(chǎn)品質(zhì)量的各要素中躍居首要地位，安全標(biāo)準(zhǔn)成為最重要的技術(shù)標(biāo)準(zhǔn)之一。
電氣安全性能試驗(yàn)儀器技術(shù)指標(biāo)完全取決于安全標(biāo)準(zhǔn)的要求和規(guī)定，測試對象除各類電子產(chǎn)品外，遍及一切電網(wǎng)供電或由指定的額定交直流供電的低壓電器設(shè)備，這是電氣安全性能試驗(yàn)儀器區(qū)別于其他各類電子測量儀器的特點(diǎn)。因此，儀器的發(fā)展依賴于安全標(biāo)準(zhǔn)的發(fā)展。
本測試裝置結(jié)構(gòu)合理，工作可靠，性能穩(wěn)定。本測試裝置特別加強(qiáng)了計(jì)算機(jī)的抗干擾措施，并且設(shè)置了自診斷、自恢復(fù)功能。因此排除了在線測試的嚴(yán)重現(xiàn)場干擾，能確保測試裝置可靠連續(xù)工作。
在工控、家電、儀器儀表、機(jī)電控制單元等領(lǐng)域，單片機(jī)已成為電子系統(tǒng)智能化的最好工具。十余年來，我國已培養(yǎng)出一大批單片機(jī)技術(shù)骨干隊(duì)伍，全國工科大專校已普遍開設(shè)了單片機(jī)相關(guān)的專業(yè)課程。單片機(jī)技術(shù)已逐漸成為電類專業(yè)學(xué)生的基本技能要求，并表現(xiàn)在相應(yīng)的課程設(shè)計(jì)、畢業(yè)設(shè)計(jì)、科學(xué)研究、各類電子技術(shù)競賽中。
由于該裝置是應(yīng)用于工廠生產(chǎn)流水線和試驗(yàn)室使用，因此，對其測量精度及整機(jī)性能有很高的要求，為了確保研制工作的有序進(jìn)行，我們在確定以單片機(jī)應(yīng)用系統(tǒng)作為開發(fā)的核心的前提下，首先應(yīng)做好對有關(guān)國家國家標(biāo)準(zhǔn)的研讀、理解和可行性調(diào)研。因?yàn)槲易龅氖切孤╇娏鳒y試，所以我做的測試應(yīng)符合GB4706.1《家用和類似用途電器的安全通用要求》系列中的要求。

ABSTRACT
Along with contemporary science technical quick development, various electric appliances,the electronics equipments enters the social activities each realm completely, becoming the important marking that the social civilization progress.At the our country, the people live level to raise continuously, is more and more big to the demand of the home appliances.Each kind of electric appliances,the electronics equipments is in the national city country and arrive to make widely available quickly, bring production biggest convenient.
Therefore, the usage safety of the electric appliances,the electronics equipments this important problem, become jumping to stand first the important position in each main factor that decides the product quality, the safe standard becomes one of the most important technique standards.The home appliances product safety standard, is for the sake of assurance Human body safety and usage the environment be free from any endanger but establishment, being a domestic expenses electricity the machine product at design,manufacturing have to act according to performance of standard document, strict performance various provision within standard, home appliances of safety have dependable assurance.
Control in the work,appliance,instrument appearance,the machine electricity control unit etc. realm, single slice the machine have become the electronics system intelligence to turn of best tool.For more than ten years, the our country has already developped one large quantity single slice the machine technique framework troops, the national engineering university school is widespread to have already set up a single slice a professional course with related machine.Single slice the machine technique has already become the basic technical ability request that gives or get an electric shock a type of professional student gradually, and express in correspond of the course design,graduation design,science research,each kind of electronics technique contest.
Electricity the safe function experiment the request and provision that the instrument technique index sign is decided by the safety standard completely, the test object in addition to each kind of electronics product, spread over the whole charged barbed wire net power supplies or from appointed of the sum certainly hands over the low-pressure electric appliances equipments of the direct current power supply, this is electricity the safe function experiment the instrument distinguish all each kind of electronicses to measure instrument of characteristics.Therefore, the development of the instrument depend on standard in the safety of development.
The origin tests device the structure reasonable, work dependable, function stable, support convenience.This test equiped to strengthen the anti- interference measure of the calculator specially, and establish from the diagnosis,from recover function.Therefore expeled an on-line test completely of serious the spot interference, can insure test to equip credibility a consecution a work.
Because that device applies to produce the flowing water line and laboratory usage in the factory, therefore, as to it's measure the accuracy and the whole machine function contain very high request, for insuring to develop to work of have a preface to carry on, we at certain the single slice is apply by machine the system Be the premise of the core of the development under, should work well standard to the concerning the nation nation first of study,the comprehension and the possibility investigation.The What I do insulates electric resistance and leaks electric current, the so I do of the test should match the the GB 4706.1 《 domestic expenses the with the the safe and the in general the use request the of the the similar use the electric appliances 》the request in the series.
In the diagram paper in this design all of me am to adopt this software of PROTEL, for this system I also want to do a simple elucidation, although I also learned this system before, mainly is drew electric circuit diagram and editted the spare parts database and born network form document.The usage of this design PROTEL this software lets me get again a good promote.
