The Position Control Computer Remote Monitoring System Research And Design

It is long-standing to control technology, and it is an important technology of an industrial field. This text involves the long- distance of monitoring and controlling for position control mainly.This system adopts one-chip computer CygnalF020 that imbeds TCP/IP as the central processing unit. RTL8019 is regarded as the network communication card. The chip which control the keyboard and such peripheral chips as the extended parallel interface ,etc, and make up the intellectual control contact, enabling the controlling module has function of networks . Thus offered the basic assurance that control long-distance. Each intellectual control contact and Upper-computer makes up industrial Ethernet. It links with Internet through gateway. And has taken many kinds of measures to strengthen the security of network.For better long-range monitor and control functions completion, this system was not confined to C/S or B/S a certain mode. It utilizes advantage of the two fully, avoid their shortcoming, and joint the two together. Realize long- distance of monitor and control with C/S structure, and B/S realizes the inquiry of the historical data. The program of Upper-computer adopts Delphi 7. The database adopts SQL Server 2000, and the database engine introduced ADO which realized the demand for the thin database. The database including position of the on-the-spot equipment database, setting-up parameter database and a small-scale knowledge expert database etc. in database including on-the-spot equipment position database, parameter. And adopt the CGI technology to connect database server in WEB server. This system adopts UDP and TCP two kinds of data transmission protocols respectively.This system has already been put into practical appllication , well received by user, practice has proved this system has very good using value and wide application prospect.
