由于熱能總廠測控區(qū)域內(nèi)附有局域網(wǎng)，考慮使用原網(wǎng)路，采用工業(yè)標(biāo)準(zhǔn)協(xié)議TCP/IP，該協(xié)議簡單實用，可連接各種檔次機器。TCP/IP協(xié)議是一套把因特網(wǎng)上的各種系統(tǒng)互連起來的協(xié)議組，保證因特網(wǎng)上數(shù)據(jù)的準(zhǔn)確快速傳輸。參考開放系統(tǒng)互連(OSI)模型，TCP/IP通常采用一種簡化的四層模型，分別為：應(yīng)用層、傳輸層、網(wǎng)絡(luò)層、鏈路層。
? 應(yīng)用層
網(wǎng)絡(luò)應(yīng)用層是一個定義清晰的會話過程，如通常所說的Http、Ftp、Telnet等。在本系統(tǒng)中，數(shù)據(jù)來自服務(wù)器和采集站，應(yīng)用層只對大的數(shù)據(jù)報作打包拆包處理。
? 傳輸層
傳輸層讓網(wǎng)絡(luò)程序通過明確定義的通道及某些特性獲取數(shù)據(jù)，如定義網(wǎng)絡(luò)連接的端口號等，實現(xiàn)該層協(xié)議的傳輸控制協(xié)議TCP和用戶數(shù)據(jù)報協(xié)議UDP。在本系統(tǒng)中使用TCP數(shù)據(jù)報協(xié)議。
? 網(wǎng)絡(luò)層
網(wǎng)絡(luò)層讓信息可以發(fā)送到相鄰的TCP/IP網(wǎng)絡(luò)上的任一主機上，IP協(xié)議就是該層中傳送數(shù)據(jù)的機制。同時為建立網(wǎng)絡(luò)間的互連，應(yīng)提供ARP地址解析協(xié)議,實現(xiàn)從IP地址到數(shù)據(jù)鏈路物理地址的映像。
? 鏈路層
控制同一物理網(wǎng)絡(luò)上的不同機器間數(shù)據(jù)傳送的底層協(xié)議。
B、系統(tǒng)組網(wǎng)模式
本系統(tǒng)采用客戶/服務(wù)器（C/S）模式。設(shè)置數(shù)據(jù)庫服務(wù)器一臺，其余各采集站、監(jiān)控站均為客戶機。C/S體系結(jié)構(gòu)是指將系統(tǒng)的設(shè)計分為服務(wù)器端和客戶機，兩端分別設(shè)計并執(zhí)行，服務(wù)器提供數(shù)據(jù)操作的各項服務(wù)，客戶機則為用戶提供最終操作界面，由此平衡了服務(wù)器及客戶機的處理負(fù)荷，大大地提高了系統(tǒng)的執(zhí)行效率，優(yōu)化了系統(tǒng)的性能，減少了網(wǎng)絡(luò)數(shù)據(jù)吞吐量和數(shù)據(jù)傳輸。服務(wù)器端是指運行大型關(guān)系型數(shù)據(jù)庫系統(tǒng)（RDBMS）的高性能服務(wù)器，客戶機是指由用戶操作的若干臺微機，在本系統(tǒng)中則為各采集站。在服務(wù)器上運行的大型關(guān)系型數(shù)據(jù)庫系統(tǒng)主要為業(yè)務(wù)數(shù)據(jù)庫的存儲、訪問、查詢、備份、恢復(fù)等操作提供一系列重要的服務(wù)，并且為數(shù)據(jù)的安全訪問等提供嚴(yán)格的權(quán)限控制；服務(wù)器端通常情況下對用戶而言是不透明的?？蛻魴C上主要運行根據(jù)業(yè)務(wù)需求定制開發(fā)的處理系統(tǒng)，包括數(shù)據(jù)統(tǒng)計、匯總、查詢、打印等多種操作功能。
