對比分析當(dāng)前環(huán)境自動監(jiān)控系統(tǒng)的優(yōu)缺點，本文介紹了基于網(wǎng)絡(luò)的環(huán)境監(jiān)測儀器遠程反控系統(tǒng)的研制和應(yīng)用。探討了廣域網(wǎng)絡(luò)采用GPRS/UDP 通信方式，局域網(wǎng)采用TCP/IP 通信方式，使用智能儀器技術(shù)和java、Applet、Servlet、oracle 等技術(shù)開發(fā)儀器反控系統(tǒng)，實現(xiàn)了在遠程客戶機的IE 瀏覽器發(fā)送控制指令控制遠程儀器進行隨機采樣，獲取采樣儀器的監(jiān)測項目和監(jiān)測狀態(tài)，并在IE 瀏覽器中實時顯示采樣數(shù)據(jù)。此方法可以代替環(huán)保局的流動采樣車，實現(xiàn)遠程隨機采樣，有效防止偷排漏排以及虛假數(shù)據(jù)等違規(guī)行為。

Abstract:Contrastively analyze advantages and disadvantages of modern enviroment automatic monitoring system.We introduce research and application of environment monitroling instrument’s remote control system based on network..In wide area network, GPRS/UDP conmmuniction method is adopted；in local area network,TCP/IP is used to realize communication between web server and clients. To develop instrument reverse control system,we use technology such as java、Applet、Servlet、oracle and communications and so on.In this system,the remote client which gets permission can send conrol commands through IE Brower to FE instrument, and then instrument starts to sample, as soon as it completes,the sample data and monitoring state data automately are transmitted to oracle database in control center,in the same time the data is displayed in IE borwser.This method can replace flow sampling cars in EPA, realizing remote random sample,effectively prevents from discharging pollutants stealthily and fasle information.
