【正文】 adaptability. Composition of direct digital control systemDirect digital control system consists of the process input channel, process control puter, the process of output channels of three parts. Process input channels from the analog input and digital input of two parts. Analog input channels from the transmitter, the sampling switch, amplifier, A / D converter and interface circuit. One is the role of the transmitter signal will be converted into the standard nonpower electrical signal，Can be temperature, pressure, flow transformed into 010mA or 420mA DC signal, it is through the A / D converter to achieve. Digital input channels from the switch contacts, photoelectric coupler and interface circuit, reflecting the production process on / off state of the contact signal, through the optocoupler and the interface circuit transformation into a digital signal sent to the puterDirect mitment to the process control puter operations and control tasks, first of all input channels through the process of collecting the parameters of the object and signals, then the scheduled control law (such as PID) for operation, and then send control signals to the controlled object, then the output channel direct control of the control valve actuatorProcess output channel from the analog output and digital output of two parts. The former control of the puter output of digital signals into analog voltage or current signals, through the amplifier to drive the actuator control valve to achieve control of the production process. This part of the interface circuit, D / A converter, amplifier and actuator ponent. Which the puter output of the switch signal by amplifier to drive solenoid valve and relay actuator, which consists of electrical interfaces, optical coupler, amplifier and actuator ponent。拼一個(gè)春夏秋冬！贏一個(gè)無(wú)悔人生！早安！—————獻(xiàn)給所有努力的人. 學(xué)習(xí)好幫手。本論文未全部顯示，總約有21435字，查看全文Abstract: This paper describes the building automation system ponents, functions, and principles of software and hardware technology, history, and related products are briefly introduced the reader of this system has a prehensive understanding of relevant professional designers for the program designed to provide a theoretical frame of reference. Keywords: building automation system, the core principle of the basic functions of hardware and software technologies1 Introduction to Building Automation System, also known as building automation system (BuildingAutomationSystem referred to as BAS), is an integral part of intelligent building, its task is the building39。組成建筑設(shè)備自動(dòng)化系統(tǒng)，必須有一種大家都能接受并且共同遵守的工作語(yǔ)言來(lái)實(shí)現(xiàn)相互之間的對(duì)話，這就是數(shù)據(jù)通信協(xié)議標(biāo)準(zhǔn)。(1)控制網(wǎng)絡(luò)特點(diǎn)分布式控制系統(tǒng)的體系結(jié)構(gòu)分布式控制系統(tǒng)(Distributed后者把計(jì)算機(jī)輸出的開關(guān)信號(hào)，經(jīng)放大器去驅(qū)動(dòng)電磁閥和繼電器執(zhí)行器，它由接口電器、光電耦合器、放大器和執(zhí)行器組成。過(guò)程輸入通道由模擬量輸入和數(shù)字量輸入兩部分組成。直接數(shù)字控制系統(tǒng)(DDC)直接數(shù)字控制系統(tǒng)(Direct(7)設(shè)備管理：包括設(shè)備檔案、設(shè)備運(yùn)行報(bào)表和設(shè)備維修管理等。根據(jù)我國(guó)行業(yè)標(biāo)準(zhǔn)，BAS又可分為設(shè)備運(yùn)行管理與監(jiān)控子系統(tǒng)和消防與安全防范子系統(tǒng)，如圖所示。 關(guān)鍵詞：樓宇自動(dòng)化系統(tǒng) 基本功能 原理核心 軟硬件技術(shù) 1(2)自動(dòng)檢測(cè)、顯示、打印各種機(jī)電設(shè)備的運(yùn)行參數(shù)及其變化趨勢(shì)或歷史數(shù)據(jù)。systems簡(jiǎn)稱DCS)。計(jì)算機(jī)通過(guò)模擬量輸入通道(AI)和開關(guān)量輸入通道(DI)采集實(shí)時(shí)數(shù)據(jù)，然后按照一定的規(guī)律進(jìn)行計(jì)算，最后發(fā)出控制信號(hào)，并通過(guò)模擬量輸出通道(AO)和開關(guān)量輸出通道(DO)直接控制生產(chǎn)過(guò)程?！獢?shù)字量輸入通道由開關(guān)觸點(diǎn)、
