描述

CAN總線最早是由德國Bosch公司推出，用于汽車內(nèi)部測量與執(zhí)行部件之間的數(shù)據(jù)通信協(xié)議。其總線規(guī)范已被ISO國際標準組織制定為國際標準，并且廣泛應(yīng)用于離散控制領(lǐng)域。它也是基于OSI模型，但進行了優(yōu)化，采用了其中的物理層、數(shù)據(jù)鏈路層、應(yīng)用層，提高了實時性。其節(jié)點有優(yōu)先級設(shè)定，支持點對點、一點對多點、廣播模式通信。各節(jié)點可隨時發(fā)送消息。傳輸介質(zhì)為雙絞線，通信速率與總線長度有關(guān)。CAN總線采用短消息報文，每一幀有效字節(jié)數(shù)為8個；當節(jié)點出錯時，可自動關(guān)閉，抗干擾能力強，可靠性高。

LonWorks技術(shù)是美國ECHELON公司開發(fā)，并與Motorola和東芝公司共同倡導的現(xiàn)場總線技術(shù)。它采用了OSI參考模型全部的七層協(xié)議結(jié)構(gòu)。LonWorks技術(shù)的核心是具備通信和控制功能的Neuron芯片。Neuron芯片實現(xiàn)完整的

LonWorks的LonTalk通信協(xié)議。其上集成有三個8位CPU。一個CPU完成OSI模型第一和第二層的功能，稱為介質(zhì)訪問處理器。一個CPU是應(yīng)用處理器，運行操作系統(tǒng)與用戶代碼。還有一個CPU為網(wǎng)絡(luò)處理器，作為前兩者的中介，它進行網(wǎng)絡(luò)變量尋址、更新、路徑選擇、網(wǎng)絡(luò)通信管理等。由神經(jīng)芯片構(gòu)成的節(jié)點之間可以進行對等通信。LonWorks支持多種物理介質(zhì)并支持多種拓撲結(jié)構(gòu)，組網(wǎng)方式靈活，其IS－78本安物理通道使得它可以應(yīng)用于危險區(qū)域。LonWorks應(yīng)用范圍主要包括樓宇自動化、工業(yè)控制等，在組建分布式監(jiān)控網(wǎng)絡(luò)方面有較優(yōu)越的性能。
