It mainly expatiates the daily examining schedule , monthly examining schedule , yearly examining schedule , new facility for use , schedule for running threshold requisition of relay protection , and then puts up the collectivity designing via hipo ( hierarchy plus input , process , output ) figure . interfaces is very important for any system . a system with no interfaces is lone . this paper discusses the interface scheme , lodging five ways : network programming , directly accessing the table of the data source database , text file , http , transmitting data through the serial interface of computer . at last this paper lodges the interface schemes of dmis aiming at the instance of chongqing power dispatch and communication central : network programming , text file , http with ems ( energy management system ) and directly accessing the table of the data source database , http with ebs ( energy business system ) 本文對接口方案進行論述,提出了五種接口方案:網絡編程、直接訪問數據源的數據庫表、形成文本文件方式、超級鏈接方式、數據通過計算機串口進行轉發,并針對重慶電力調度通信中心的具體情況提出了dmis的接口方法:與ems ( energymanagementsystem )的接口采用網絡編程、形成文本文件方式、超級鏈接方式,與ebs ( energybusinesssystem )的接口采用直接訪問數據源的數據庫表、超級鏈接方式。
