4 系統(tǒng)功能的實(shí)現(xiàn)

數(shù)據(jù)圖形顯示：包括實(shí)時(shí)數(shù)據(jù)趨勢顯示、歷史數(shù)據(jù)趨勢顯示(顯示的時(shí)間區(qū)間可改變)、棒狀圖顯示、流程圖顯示。

數(shù)據(jù)查詢：可查詢兩個(gè)月前的歷史數(shù)據(jù)記錄、報(bào)警記錄等。

報(bào)表打印：包括報(bào)警記錄打印、月報(bào)表、輪值信息打印、燃煤量報(bào)表、發(fā)電量報(bào)表打印。

人工輸入：為了滿足一些數(shù)據(jù)的特殊要求，運(yùn)行人員每隔一小時(shí)將一些數(shù)據(jù)從鍵盤上輸入到人工輸入一覽表中。

在線分析：包括發(fā)電量分析、燃煤量分析、事故分析等。

權(quán)限設(shè)定：為了更好地維護(hù)系統(tǒng)，對不同的操作站設(shè)定不同的權(quán)限，一些高級的操作只有工程師站或管理員站獨(dú)用，而操作員站只進(jìn)行日常的運(yùn)行、維護(hù)操作。并且不同的操作級別設(shè)定不同的密碼，不同的操作站只能登錄相應(yīng)級別的權(quán)限。

系統(tǒng)對時(shí)與更改時(shí)間：由于本系統(tǒng)是網(wǎng)絡(luò)結(jié)構(gòu)，需要保持整個(gè)網(wǎng)絡(luò)系統(tǒng)時(shí)間一致。權(quán)限為管理員站的操作站可進(jìn)行系統(tǒng)對時(shí)和更改系統(tǒng)時(shí)間。系統(tǒng)對時(shí)以網(wǎng)絡(luò)控制機(jī)的時(shí)間為準(zhǔn)。

與廠級管理信息系統(tǒng)(MIS)相接：在上位機(jī)任一PC總線插槽插入-LAN網(wǎng)卡與廠級MIS相連接，將發(fā)電機(jī)組的實(shí)時(shí)信息傳至廠級管理機(jī)構(gòu)。
