The meter ( which is called pccm2002 for short ) is designed on the basis of mcs-51 single-chip microcomputer technique . the hardware is composed of single-chip microcomputer module and electrochemical module . the single-chip microcomputer module can be divided into five parts, cpu circuit, a / d and d / a circuit, peripheral memory circuit, i / o interface circuit, distributing address circuit; the electrochemical module is made up of potentiostatic circuit, galvanostatic circuit, potentiostatic-galvanostatic ( p-g ) conversion circuit, signal measuring circuit . the software of the meter is edited by c51 language, it is well-structured and module . all program modules have been linked into an executable files after compiled separately, then copy to eprom 恒電位控制下的恒電量智能化腐蝕監(jiān)測(cè)儀采用基于mcs-51單片機(jī)技術(shù)的智能化設(shè)計(jì),儀器硬件由單片機(jī)系統(tǒng)模塊和電化學(xué)接口模塊組成,單片機(jī)系統(tǒng)模塊包括cpu電路,片外存貯器擴(kuò)展電路,模數(shù)和數(shù)模(ad和da)電路,輸入輸出(io)接口電路,地址分配電路,各電路模塊通過(guò)系統(tǒng)總線交換信息;電化學(xué)接口模塊主要由恒電位電路,恒電流電路,恒電位-恒電流(p-g)轉(zhuǎn)換電路,信號(hào)放大與采集電路組成。
Automatization and intelligent are the general developmental inclination in instruments and meters, the intelligent corrosion monitor based on microcomputer technique has been a new direction in corrosion monitoring . the process and tendency at home and abroad in intelligent corrosion monitor are reviewed in this paper, at the same time, an coulostatic corrosion monitor under potentiostatic control has also been introduce, which widen the application of coulostatic technology 智能化和自動(dòng)化已成為當(dāng)今儀器儀表發(fā)展的潮流,以計(jì)算機(jī)技術(shù)為控制內(nèi)核的智能化腐蝕監(jiān)測(cè)儀成為腐蝕監(jiān)測(cè)重要發(fā)展方向。本文綜述了腐蝕監(jiān)測(cè)儀的發(fā)展過(guò)程,并對(duì)其發(fā)展趨勢(shì)進(jìn)行了分析,研制了恒電位控制下的恒電量智能化腐蝕監(jiān)測(cè)儀,擴(kuò)大了恒電量法在腐蝕監(jiān)測(cè)中的應(yīng)用范圍。
This thesis is on the basis of analyzing the main technical parameter of the diesel locomotive in detail . directed against the backward state of the original testing equipment, propose and adopt advanced microcomputer technique, and control technology and test detection technique for the testbed go on technological scheme that transform . using the design philosophy of the module ization, carry on the design of soft and hardware to every function module, thus form a microcomputer detecting system of the hydraulic resistance testbed for diesel locomotive 本文在對(duì)內(nèi)燃機(jī)車主要技術(shù)參數(shù)進(jìn)行詳細(xì)分析的基礎(chǔ)上,針對(duì)原有試驗(yàn)設(shè)備的落后狀況,提出了采用先進(jìn)的微機(jī)技術(shù)、傳感器檢測(cè)技術(shù)和控制技術(shù)對(duì)水阻試驗(yàn)臺(tái)進(jìn)行改造的技術(shù)方案,應(yīng)用模塊化的設(shè)計(jì)思想,對(duì)各功能模塊進(jìn)行軟、硬件設(shè)計(jì),從而構(gòu)成內(nèi)燃機(jī)車水阻試驗(yàn)臺(tái)微機(jī)檢測(cè)系統(tǒng)。
