【正文】 d network interface, they all have their own special network address (nodes), can send and receive data through the network, the network of each node in equal status, can share resources and interdependent, form a unified mand, and has the function of the dispersed risk, network architecture area is of great flexibility, scalability, can satisfy the distributed control system with the need to upgrade, the expansion is flexible and convenient(1) control network characteristics of distributed control system is different from the general puter network munication network, and general munication network, it is as follows: (1) have special requirements, high reliability and safety requirements of information transmission, therefore absolutely accurate, reliable and often USES redundant technology, backup and diagnosis function. Such as: control station adopt double CPU boards, double I / 0 plate, etc. 2 good performance. 3 strong adaptability to environment. (2) network topology construction equipment automation systems monly used have bus network and ring network, in two kinds of structure of two nodes can be directly through the network munication, each node in equal status(3) network munication protocol ponent architecture equipment automation system, there must be a kind of everybody can accept and abide by the working language to realize mutual dialogue, this is the data munication protocol standards. Used for building automation control network BACnet agreement by the physical layer, data link layer and network layer and network ponents, or the equivalent of open systems interconnection reference model (OSI) first, second, third, seven layer protocol Among them: ARCnet for token bus network, data transfer rate of , have a good time. MS/TP is a main/transmission from the data link layer technique, allows the use of EIA 485 hardware. BACnet achieve different manufacturer of automatic control system of munication between technology, ., from a island to another island relationship between the technology5 Conclusions building automation control technology in China is still an emerging technology, with the emergence of more intelligent building, there will be more advanced technology to add to this area, so the technology is more mature and improve寧可累死在路上，也不能閑死在家里！寧可去碰壁，也不能面壁。用于建筑自動化控制網(wǎng)絡(luò)的BACnet協(xié)議由物理層、數(shù)據(jù)鏈路層、網(wǎng)絡(luò)層和應(yīng)用層組成，或相當(dāng)于開放系統(tǒng)互聯(lián)參考模型(OSI)的第一、二、三、七層協(xié)議其中：ARCnet為令牌總線網(wǎng)，數(shù)據(jù)傳輸速率為2．520bit／s，有良好的實時性。分布式控制系統(tǒng)的通信網(wǎng)絡(luò)不同于通用計算機網(wǎng)絡(luò)，與一般的通信網(wǎng)絡(luò)比較，它有如下特殊要求：①有高可靠性和安全性，要求傳遞的信息絕對準(zhǔn)確、可靠，為此常采用冗余技術(shù)、后備措施和自診斷功能。Control3．1．2模擬量輸入通道由變送器、采樣開關(guān)、放大器、A／D轉(zhuǎn)換器和接口電路組成。Digital3一般情況下，這兩個子系統(tǒng)宜一同納入BAS考慮，如將消防與安全防范子系統(tǒng)獨立設(shè)置，也應(yīng)與BAS監(jiān)控中心建立通信聯(lián)系以便災(zāi)情發(fā)生時，能夠按照約定實現(xiàn)操作權(quán)轉(zhuǎn)移，進行一體化的協(xié)調(diào)控制。. . . .. .中英文 智能樓宇自動化系統(tǒng)摘要：本文詳細(xì)介紹了樓宇自動化系統(tǒng)的組成、基本功能、原理、核心的軟硬件技術(shù)、發(fā)展歷史，并對相關(guān)產(chǎn)品做了簡要介紹，使讀者對該系統(tǒng)有一個全面的認(rèn)識，也為相關(guān)專業(yè)設(shè)計人員的方案設(shè)計提供了理論上的參考依據(jù)。建筑設(shè)備自動化系統(tǒng)的基本功能可以歸納如下：(1)自動監(jiān)視并控制各種機電設(shè)備的起、停，顯示或打印當(dāng)前運轉(zhuǎn)狀態(tài)。樓宇自動化控制系統(tǒng)的原理樓控系統(tǒng)采用的是基于現(xiàn)代控制理論的集散型計算機控制系統(tǒng)，也稱分布式控制系統(tǒng)(DistributedcontrolControl簡稱DDC)如圖2所示。其中變送器的作用是將非電量信號變換成標(biāo)準(zhǔn)電信號，可將溫度、壓力、流量變換成010mA或42
