風(fēng)景名勝區(qū)是"美麗中國"的重要載體,是生態(tài)文明的集中展示地,因此也是生態(tài)文明建設(shè)的重要對象。
云龍湖,西湖的姊妹湖,5A級旅游景區(qū),大詩人蘇軾的筆下是這樣稱贊它的:
“一湖碧水青山連,朝暉暮陰景萬千;漁舟唱晚燕歸來,良辰美景在人間?!?br />
云龍湖風(fēng)景名勝區(qū)素有“徐州名勝之冠”的美譽,風(fēng)景區(qū)面積44.7平方公里,水域面積7.5平方公里,距離徐州市中心僅3公里。云龍湖不僅是大型觀光勝地,也是城市水域的一部分,水體生態(tài)保護首當其沖。
云龍湖也經(jīng)歷過水質(zhì)較差、水污染嚴重的時期,自動化排水泵站在云龍湖的水質(zhì)改造中發(fā)揮了重要作用,經(jīng)過多年持續(xù)開發(fā)治理,水質(zhì)達到“飲用水”標準。同時,云龍湖作為大型水庫,承擔(dān)著蓄水調(diào)洪和水源涵養(yǎng)的重要功能,需要實現(xiàn)控源截污,清淤貫通,活水補給等保障功能,應(yīng)用先進的泵站自動化系統(tǒng)來實現(xiàn)這一更高標準。
自動化技術(shù)進步和大量新興技術(shù)的融合,泵站自動化控制及系統(tǒng)管理能力得以升級。2019年,云龍湖風(fēng)景區(qū)對沿線四條河道口門控制及云龍湖泵站進一步改造,中礦創(chuàng)慧作為項目中標人承擔(dān)了泵站改造工程,建立物聯(lián)網(wǎng)泵站群集控系統(tǒng)實現(xiàn)了無人值守、遠程維護、泵站調(diào)度、能耗降低等功能。
藍普鋒作為國內(nèi)可編程控制器(PLC)的優(yōu)秀品牌廠商,在水處理、環(huán)保自動化領(lǐng)域有眾多案例成果,擁有非常豐富的經(jīng)驗,成為該項目的合作伙伴。
泵站群集控系統(tǒng)是以PLC為核心,實現(xiàn)泵站群的自動控制和調(diào)度管理,以確保大型水庫的安全運行。
該方案,采用藍普鋒高性能的RPC2000系列PLC,實現(xiàn)對水庫水位和水泵運行狀況的實時監(jiān)測、泵站群的網(wǎng)絡(luò)級聯(lián)、泵站群的自動化控制和調(diào)度管理,采集三相電參數(shù)用于能耗分析。
物聯(lián)網(wǎng)智能監(jiān)控系統(tǒng)通過RPC2000系列PLC采集泵站群數(shù)據(jù),與監(jiān)控系統(tǒng)進行數(shù)據(jù)交互,實現(xiàn)信息共享,完成水庫水位監(jiān)測、泵站開關(guān)啟停、報警信息處理等功能。
在實時監(jiān)控和監(jiān)測運維方面,依托RPC2000系列PLC的采集和通訊能力,完善數(shù)據(jù)分析結(jié)果,對所有設(shè)備進行優(yōu)化控制,進行預(yù)測性維護,延長水泵使用壽命。
通過授權(quán),管理人員可通過電腦、手機隨時隨地獲取泵站群信息,實現(xiàn)遠程調(diào)度和管理,達到泵站群“無人值班(少人值守)”的要求。
PLC硬件配置部分,結(jié)合現(xiàn)場多網(wǎng)絡(luò)通訊需求和泵站控制和采集點需求,CPU模塊選用16路I/O支持4路通訊口的RPC2107N,擴展模塊包括:RPC2211支持16路DI,RPC2310支持4路AI輸入,和電參數(shù)輸入模塊RPC2731。
