YASKAWA JANCD-XCP0101C-1半導體模塊,JANCD-XCP0101C-1使用范圍
通過(guò)標準Modbus-RTU協(xié)議主動(dòng)向安裝在受監測點(diǎn)的各用能用水點(diǎn)的具遠傳功能的計量?jì)x表采集相關(guān)數據,并通過(guò)GPRS無(wú)線(xiàn)模塊以GSM通訊方式傳輸匯總至公共機構節能監管平臺集中綜合統一處理。GPRS是一種新型的移動(dòng)通訊業(yè)務(wù)JANCD-XCP0101C-1,在移動(dòng)用戶(hù)和數據網(wǎng)絡(luò )之間建立一種連接,給移動(dòng)用戶(hù)提供高速無(wú)線(xiàn)IP或X.25服務(wù),GPRS采用分組交換技術(shù),每個(gè)用戶(hù)可同時(shí)占用多個(gè)無(wú)線(xiàn)信道,
同時(shí)一個(gè)無(wú)線(xiàn)信道又可以供多個(gè)用戶(hù)共享,資源被有效的利用,數據闡述速率高達160Kbps,使用GPRS通訊方式實(shí)現數據的分組發(fā)送和接收,用戶(hù)永遠在線(xiàn)且按流量計費,高速且降低服務(wù)成本。
基于GPRS的建筑能耗節能監管安全系統具有以下特點(diǎn):
a) 永遠在線(xiàn):GPRS DTU一開(kāi)機即可自動(dòng)附著(zhù)至GPRS網(wǎng)絡(luò )上,并與數據中心建立通信鏈路,隨時(shí)接受發(fā)送用戶(hù)數據設備的數據,功能強大,具有高實(shí)時(shí)性;
b) 按流量計費:GPRS DTU一直在線(xiàn),按照接收和發(fā)送的數據包的數量來(lái)收取費用,沒(méi)有數據流量傳遞時(shí)不收取費用,節約成本;YASKAWA JANCD-XCP0101C-1半導體模塊
c) 高速傳輸GPRS網(wǎng)絡(luò )的傳輸速度最快可達到160Kbps,速度的高低取決于移動(dòng)運營(yíng)商的網(wǎng)絡(luò )設置,根據中國移動(dòng)的網(wǎng)絡(luò )情況,目前可提供20~40 Kbps的穩定數據傳輸;
d) 組網(wǎng)簡(jiǎn)單、迅速、靈活,GPRS無(wú)線(xiàn)系統可以通過(guò)Internet網(wǎng)絡(luò )隨時(shí)隨地的構建覆蓋全中國的虛擬移動(dòng)通信準用網(wǎng)絡(luò ),為廣大中小用戶(hù)提供接入便利,節省接入投資

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.
