IC693MDL340H 其中嵌入式Web服務(wù)器和監(jiān)控端位于現(xiàn)場(chǎng)，它們之間的連接可以用串行口、并行口、USB等實(shí)現(xiàn)。現(xiàn)場(chǎng)監(jiān)控端完成對(duì)目標(biāo)地區(qū)電網(wǎng)參數(shù)（電壓、電流、諧波等數(shù)據(jù)）的檢測(cè)，并將檢測(cè)結(jié)果實(shí)時(shí)傳送至web界面，使得無(wú)論監(jiān)控人員在哪里，只要連接至Internet網(wǎng)絡(luò)，便可對(duì)目標(biāo)區(qū)域電網(wǎng)參數(shù)實(shí)時(shí)觀測(cè)。其實(shí)現(xiàn)過程是：三相電壓、電流分別通過電壓互感器、電流互感器變換后，經(jīng)電路調(diào)理送至AID轉(zhuǎn)換，每周期采樣128點(diǎn)，DSP芯片對(duì)采樣數(shù)據(jù)進(jìn)行FIR數(shù)字濾波、FFT運(yùn)算、計(jì)算各參數(shù)值、存儲(chǔ)、顯示等操作。測(cè)量電路與Nios之間的通信通過串口傳輸，根據(jù)事先約定的通信協(xié)議（基于Modbus協(xié)議）可以方便地把所測(cè)數(shù)據(jù)發(fā)送至以Nios II處理器為核心的嵌入式服務(wù)器。通過CGI技術(shù)，完成遠(yuǎn)程監(jiān)控端的命令傳輸及將測(cè)量數(shù)據(jù)實(shí)時(shí)傳送至遠(yuǎn)程監(jiān)控端。

2、硬件結(jié)構(gòu)
系統(tǒng)的硬件結(jié)構(gòu)如圖2所示。硬件系統(tǒng)的核心是構(gòu)建于Ahera Cyclone FPGA中的Nios II嵌入式軟核處理器。Nios II系列嵌入式處理器是一款通用的RISC結(jié)構(gòu)的CPU，它定位于廣泛的嵌入式應(yīng)用。Nios II處理器系列包括了三種核心：快速的（Nios II／f）、經(jīng)濟(jì)的（Nios II／e）和標(biāo)準(zhǔn)的（Nios II／s）內(nèi)核，每種都針對(duì)不同的性能范圍和成本而優(yōu)化。這三種核都使用共同的32位的指令集結(jié)構(gòu)（ISA），都兼容二進(jìn)制代碼。
圖2 硬件系統(tǒng)圖
對(duì)于Nios II的配置在SOPC Builder中完成。通過配置所需要的外部/內(nèi)部元件，SOPC Builder將自動(dòng)生成適合選定元件的CPU，以符合系統(tǒng)的需求。16M的CF卡作為系統(tǒng)的外存儲(chǔ)器，用來(lái)存儲(chǔ)測(cè)量數(shù)據(jù)，網(wǎng)頁(yè)文件和應(yīng)用程序。以太網(wǎng)接口芯片采用的SMSC的Lan91cl11芯片，這是一種非PCI接口的單芯片網(wǎng)絡(luò)控制器，具有8k的FIFO，可以實(shí)現(xiàn)和8位、16位、32位的CPU接口，廣泛地應(yīng)用于嵌入式系統(tǒng)設(shè)計(jì)中。
