YASKAWA JANCD-XCP0101C-1半導體模塊,JANCD-XCP0101C-1使用范圍
通過標準Modbus-RTU協(xié)議主動向安裝在受監(jiān)測點的各用能用水點的具遠傳功能的計量儀表采集相關數(shù)據,并通過GPRS無線模塊以GSM通訊方式傳輸匯總至公共機構節(jié)能監(jiān)管平臺集中綜合統(tǒng)一處理。GPRS是一種新型的移動通訊業(yè)務JANCD-XCP0101C-1,在移動用戶和數(shù)據網絡之間建立一種連接,給移動用戶提供高速無線IP或X.25服務,GPRS采用分組交換技術,每個用戶可同時占用多個無線信道,
同時一個無線信道又可以供多個用戶共享,資源被有效的利用,數(shù)據闡述速率高達160Kbps,使用GPRS通訊方式實現(xiàn)數(shù)據的分組發(fā)送和接收,用戶永遠在線且按流量計費,高速且降低服務成本。
基于GPRS的建筑能耗節(jié)能監(jiān)管安全系統(tǒng)具有以下特點:
a) 永遠在線:GPRS DTU一開機即可自動附著至GPRS網絡上,并與數(shù)據中心建立通信鏈路,隨時接受發(fā)送用戶數(shù)據設備的數(shù)據,功能強大,具有高實時性;
b) 按流量計費:GPRS DTU一直在線,按照接收和發(fā)送的數(shù)據包的數(shù)量來收取費用,沒有數(shù)據流量傳遞時不收取費用,節(jié)約成本;YASKAWA JANCD-XCP0101C-1半導體模塊
c) 高速傳輸GPRS網絡的傳輸速度最快可達到160Kbps,速度的高低取決于移動運營商的網絡設置,根據中國移動的網絡情況,目前可提供20~40 Kbps的穩(wěn)定數(shù)據傳輸;
d) 組網簡單、迅速、靈活,GPRS無線系統(tǒng)可以通過Internet網絡隨時隨地的構建覆蓋全中國的虛擬移動通信準用網絡,為廣大中小用戶提供接入便利,節(jié)省接入投資

公共機構節(jié)能監(jiān)管平臺基于杭州優(yōu)穩(wěn)自動化系統(tǒng)有限公司全自主知識產權的UWin Pro監(jiān)控管理軟件進行集中分析、判斷、評估、管理、記錄等。UWin Pro監(jiān)控管理軟件集工程管理器(UWinWks)、系統(tǒng)硬件配置軟件(UWinCFG)、實時數(shù)據庫(UWinRDB)、歷史記錄組態(tài)(UWinHDB)、設備管理器(UWinDev)、畫面開發(fā)系統(tǒng)(UWinView)
staggered by 30 °, and the frequency of the circulating current voltage is L2 times the power frequency. In order to suppress AC circulating current, two equalizing reactors are connected between two groups of controllable rectifier bridges, and one smoothing reactor is still reserved in the armature circuit.
The control circuit is mainly composed of speed regulator ASR, current regulator ACR, circulating current regulator arr, positive group trigger GTD, negative group trigger GTS and current feedback TCV (see Figure 2). The synchronization signals of the two groups of triggers are respectively taken from the synchronous transformer corresponding to the rectifier transformer.
