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 ) 本文对接口方案进行论述，提出了五种接口方案：网络编程、直接访问数据源的数据库表、形成文本文件方式、超级链接方式、数据通过计算机串口进行转发，并针对重庆电力调度通信中心的具体情况提出了dmis的接口方法：与ems ( energymanagementsystem )的接口采用网络编程、形成文本文件方式、超级链接方式，与ebs ( energybusinesssystem )的接口采用直接访问数据源的数据库表、超级链接方式。
