近些年來，隨著我國居民住宅建設(shè)的迅速發(fā)展，城市樓房所用電能表的數(shù)量也日益增多?，F(xiàn)行建筑電氣設(shè)計常將單塊電能表集中掛成一面“表墻”，體積較大，維護(hù)管理不便[1]。如在智能小區(qū)、學(xué)生公寓等場所，分戶計量時每層需安裝多塊電表，

1 功能介紹：
本文設(shè)計的多回路電能管理終端的主要包括以下功能：
計量：可計量每個回路的尖、峰、平、谷各時段的電能及總電能，精度為1級。
檢測：實(shí)時檢測各回路的相電壓、有功功率、無功功率、功率因數(shù)、電壓頻率等。
設(shè)置：可以自由設(shè)置復(fù)費(fèi)率的時段、時間及通訊參數(shù)。
顯示：實(shí)時顯示各回路的用電量。
通信：通過RS485接口進(jìn)行遠(yuǎn)程抄表，可支持Modbus與DL/T 645-2007協(xié)議。
2 設(shè)計方案
本終端的設(shè)計包括硬件設(shè)計與軟件設(shè)計兩個部分。
2.1硬件設(shè)計
主控部分硬件包括：MCU、LED數(shù)碼顯示、時鐘電路、RS485通訊、按鍵輸入。其中，顯示界面采用的是LED數(shù)碼管，用戶可以通過輪顯顯示來了解當(dāng)前的使用電量和剩余電量；通訊采用兩路RS485，一路為主控模塊與電腦、通訊管理機(jī)等設(shè)備之間的通訊，另外一路為主控模塊與計量模塊之間的通訊。
計量部分硬件包括：計量芯片、鐵電存儲、磁保持控制電路、有功脈沖輸出、信號輸入。其中，計量芯片對電壓、電流信號分別進(jìn)行采集，并將有功電能數(shù)據(jù)存儲至鐵電中，用于后續(xù)數(shù)據(jù)的查看、對比。每個計量部分和主控部分之間采用RS485通訊，以進(jìn)行數(shù)據(jù)處理和控制。多回路計量終端采集到的電能最終會存儲至鐵電中。具體的硬件處理流程如圖1所示。
