　　數(shù)據(jù)采集是配電監(jiān)控的基礎，數(shù)據(jù)采集主要由底層多功能網(wǎng)絡儀表采集完成，實現(xiàn)遠程數(shù)據(jù)的本地實時顯示。需要完成采集的信號包括：三相電壓U、三相電流I、頻率Hz、功率P、功率因數(shù)COSφ、電度EpI、遠程設備運行狀態(tài)等數(shù)據(jù)。

　　數(shù)據(jù)處理主要是把按要求采集到的電參量實時準確的顯示給用戶，達到配電監(jiān)控的自動化化和智能化要求，同時把采集到的數(shù)據(jù)存入數(shù)據(jù)庫供用戶查詢。

　　Data collection is the basis of power distribution monitoring. The data collection is mainly completed by the bottom multi-functional network instrument collection to realize the local real-time display of remote data. 

　　The signals that need to be collected include: three-phase voltage U, three-phase current I, frequency Hz, power P, power factor COSφ, electricity EpI, remote device operating status and other data.

　　Data processing is mainly to display the electrical parameters collected as required to users in real time and accurately to meet the requirements of automation and intelligence for power distribution monitoring. At the same time, the collected data is stored in the database for users to query.

2.2 人機交互Human-computer interaction

　　系統(tǒng)提供簡單、易用、良好的用戶使用界面。采用全中文界面，圖形顯示低壓配電系統(tǒng)電氣一次主接線圖，顯示配電系統(tǒng)設備狀態(tài)及相應實時運行參數(shù)，畫面定時輪巡切換；畫面實時動態(tài)刷新；模擬量顯示；開關(guān)量顯示；連續(xù)記錄顯示等。

　　The system provides a simple, easy-to-use and good user interface. Adopt full Chinese interface, graphically display the primary electrical wiring diagram of low-voltage power distribution system, display the status of power distribution system equipment and corresponding real-time operating parameters, the screen will switch regularly; the screen will be dynamically refreshed in real time; analog display; switch display; continuous recording display etc.

2.3 歷史事件Historical events

　　歷史事件查看界面主要為用戶查看曾經(jīng)發(fā)生過的故障記錄、信號記錄、操作記錄、越限記錄提供方便友好的人機交互，通過歷史事件查看平臺，您可以根據(jù)自己的要求和查詢條件方便定位您所要查看的歷史事件，為您把握整個系統(tǒng)的運行情況提供了良好的軟件支持。

　　The historical event viewing interface mainly provides convenient and friendly human-computer interaction for users to view the fault records, signal records, operation records, and limit violation records that have occurred. Through the historical event viewing platform, you can conveniently locate the historical event you want to view according to your own requirements and query conditions, and provides good software support for you to grasp the operation of the entire system.

2.4 數(shù)據(jù)庫建立與查詢Database establishment and query

　　主要完成遙測量和遙信量定時采集，并且建立數(shù)據(jù)庫，定期生成報表，以供用戶查詢打印。

　　It mainly completes the timing collection of remote measurement and remote information, and establishes a database, and generates reports on a regular basis for users to query and print.

2.5 用戶權(quán)限管理User authority management

　　針對不同級別的用戶，設置不同的權(quán)限組，防止因人為誤操作給生產(chǎn)，生活帶來的損失，實現(xiàn)配電系統(tǒng)的安全，可靠運行。可以通過用戶管理進行用戶登錄、用戶注銷、修改密碼、添加刪除等操作，方便用戶對賬號和權(quán)限的修改。

　　For users of different levels, different authority groups are set to prevent the loss of production and life due to human misoperation, and realize the safe and reliable operation of the power distribution system.Users can log in, log out, modify passwords, add and delete operations through user management, which is convenient for users to modify accounts and permissions.

2.6 報表查詢Report query

　　報表管理程序的主要功能是根據(jù)用戶的需要設計報表樣式，把系統(tǒng)中處理的數(shù)據(jù)經(jīng)過篩選、組合和統(tǒng)計生成用戶需要的報表數(shù)據(jù)。本程序還可以根據(jù)用戶的需要對報表文件采用定時保存、打印或者召喚保存、打印模式。同時本程序還向用戶提供了對生成的報表文件管理功能。

　　報表具有自由設置查詢時間實現(xiàn)日、月、年的電能統(tǒng)計，數(shù)據(jù)導出和報表打印等功能。

　　The main function of the report management program is to design report styles according to the needs of users, filter, combine and count the data processed in the system to generate report data that users need.This program can also adopt the regular saving, printing or summon saving and printing modes for the report file according to the needs of users.At the same time, this program also provides users with the function of managing the generated report files.

　　The report has the functions of freely setting the query time to realize the electric energy statistics of the day, month and year, data export and report printing.
