本書第一部分講述的是傳統(tǒng)的網(wǎng)絡(luò)接口N e t B I O S、重定向器以及通過重定向器進(jìn)行的各類
網(wǎng)絡(luò)通信。盡管本書大部分內(nèi)容均圍繞Wi n s o c k編程這一主題展開，但是， A P I比起Wi n s o c k
來，仍然具有某些獨(dú)到之處

隨著光伏發(fā)電系統(tǒng)快速發(fā)展,以及電動(dòng)汽車充電樁的普及,傳統(tǒng)的剩余電流保護(hù)器無法滿足實(shí)際需求。介紹了一款B型剩余電流保護(hù)器,采用磁調(diào)制剩余電流互感器和零序電流互感器采集剩余電流。根據(jù)GB/T 22794—2017標(biāo)準(zhǔn)要求,可識(shí)別1 kHz及以下的正弦交流、帶和不帶直流分量的脈動(dòng)直流、平滑直流等剩余電流信號(hào)。經(jīng)信號(hào)調(diào)理電路將電壓信號(hào)送到單片機(jī)進(jìn)行采集和判斷。通過試驗(yàn)測(cè)試,該樣機(jī)在測(cè)試精度和速度上均符合國家標(biāo)準(zhǔn)的相關(guān)要求。The rapid development of photovoltaic power generation systems and the popularity of electric vehicle charging piles make the traditional residual current protective devices unable to meet the actual demand.This paper proposed a type B residual current protective device,which uses the magnetically modulated residual current transformer and the zero sequence current transformer to acquire the residual current.According to the requirements of GB/T 22794—2017,the type B residual current protective device can detect sinusoidal AC residual current of 1kHz and below 1kHz,pulsating DC residual current with and without DC component,smooth DC residual current and so on.The signal processing circuit sends the voltage signal to the MCU for acquisition and judgment.Through experimental tests,the device meets the relevant requirements of national standards in terms of test accuracy and speed.
