    產品概述

           自來水公司,大型企業等單位由于需要實現跨區域甚至跨城域管理,采用人工近距離無線抄讀亦無法滿足其抄表實時性要求。針對這一需求可采用基于GPRS型的無線大口徑水表集中抄表方案。該方案由大口徑水表,GPRS采集模塊,管理系統三部分組成。大口徑水表所計量的數據,按照系統設定的時間間隔保存,并可根據預先設定的上報周期把水表數據通過GPRS/CDMA信道連接至Internet,并把數據自動傳輸至具有固定IP的數據中心計算機上,通過與管理系統的對接進行數據存儲、統計、分析。



    產品參數

    規格及技術參數

    環境溫度-25℃-70℃
    相對溫度≤90%
    大氣壓力80Kpa-120Kpa
    最大功耗≤2W
    通訊時長1~2s




    性能特點

    采用GPRS通訊技術具有實時在線特性,系統無延時,可以同步接收,處理多個數據采集點的數據,對大口徑水表的工作狀態進行動態監測;

    采集模塊采用高氣壓密封艙設計,接頭部分采用IP68級防水部件,適合水表井內工作環境;

    采用模塊無需外部供電,雙備份電池設計,保證了數據永不丟失,采集核心內置高能鋰電池可保證工作6年以上,外置大容量可更換電池,如按2小時一次主動上報周期的情況下,可連續工作3.5年左右

    支持多路采集,在統一管道井內可對4只水表進行采集和管理;

    支持本地設置RS485接口,可進行本地設置和遠程設置,方便維護,降低設備調試、檢修、維護的工作量;

    數據傳輸速率高,GPRS網絡傳送速率理論上可達171.2kbit/s,實際傳輸速率在40Kbps,通信費用低,用戶可根據情況采用包月或包年不限流量的方式;

    安裝使用方便,GPRS采集模塊和水表間只需要連接一條485總線連接,并配有蛇形護套線。
