本文提出由設(shè)備網(wǎng)，控制網(wǎng)，電力以太網(wǎng)三級診斷網(wǎng)絡(luò)構(gòu)建電力設(shè)備診斷平臺(tái)，描述
了其結(jié)構(gòu)和功能。詳細(xì)介紹了基于dsPIC30F 的現(xiàn)場診斷裝置的軟硬件結(jié)構(gòu)，雙CPU 結(jié)構(gòu)的任務(wù)模型及模擬量的采集方法；最后對診斷平臺(tái)的網(wǎng)絡(luò)接口也作了討論。該診斷平臺(tái)經(jīng)過實(shí)驗(yàn)證明，工作可靠，滿足對電力設(shè)備在線診斷的技術(shù)要求。
關(guān)鍵詞：診斷網(wǎng)絡(luò)，dsPIC30F，雙CPU 結(jié)構(gòu)；
Abstract：Fault diagnosis system of power device, which is build in device-net、 control-net、 power eth-net is given in the paper, and the structure & function are also described. The hardware and software of the diagnosis& monitor instrument based on the Dspic30F are provided, including task-model of the double –CPU, the technique of sampling to the analogy. In addition, the net-interface of diagnosis system was discussed. Practice in lab show: the system reliability, the function to on-line fault diagnosis of the power device is satisfied.
