Abstract
The invention discloses a WEB publishing method of AVC (Automatic Voltage Control) equipment's real-time data. The method puts browser data in constant refreshing, so that the browser can be synchronized with data on AVC servers. And as the WEB server and the AVC servers are deployed separately, the CPU load of the AVC servers is reduced while the reliability of AVC regulation is increased. The separate deployment ensures the stability of the AVC servers and allows performance progress of a WEB server from the rapid development of Web service technology. When a WEB server is connected to multiple AVC servers, centralized management can be effectively achieved to the AVC servers with the consequences that fault warnings are available in the browser instantly and that system coupling is reduced. Under some condition when the WEB server has to be restarted, the regulation performance of the AVC servers is not affected. All these advantages promise the method good prospects for applications.
