集中抄表系統的技術規劃
集中抄表系統一
套符合電力行業的集中抄表系統應具備以下條件和要求：
抄表的見表率必須是100％，抄表數據准確率必須是100％。
抄表系統需采用集中抄表方式以節省人力物力。
抄表系統的上下行通信方式必需穩定、安全、可靠。
抄表系統必需能與電力營銷軟件進行數據交流，計算電費。
抄表系統應具備對用戶表計進行遠程停送電的功能，以加強電費的回收。
抄表系統應具備自動巡查系統故障並報警的功能，以便及時發現故障采取措施
無線抄表系統方式介紹
『單元集中式』現場無線抄表,本系統是主站與掌上電腦之間采用連線傳輸方式通訊，掌上電腦(modbus主機)與集中器之間采用短距離無線電信號進行通訊，集終端與電表之間采用RS485方式通訊。
