The construction of the integrated data transmission network of electric power system 電力調(diào)度專用數(shù)據(jù)網(wǎng)絡(luò)技術(shù)體制的探討
Focusing on the real - time performance , the design of data transmission network and embedded data acquisition device is discussed 為滿足系統(tǒng)的實(shí)時(shí)性要求,分別討論了系統(tǒng)中的數(shù)據(jù)傳輸網(wǎng)絡(luò)和嵌入式數(shù)據(jù)采集裝置的設(shè)計(jì)。
First the feasibility of using ethernet in industrial environment is analyzed , using switched ethernet as substation insulation information transmission network and using tcp / ip protocol suite as the protocols of higher layers is suggested . the factors affecting the real - time performance of data transmission network is presented and the method to improve the performance of ip protocol stack and reduce the traffic of network is focused 首先分析了以太網(wǎng)應(yīng)用于工業(yè)環(huán)境的可行性,提出使用交換式以太網(wǎng)作為變電站絕緣信息傳輸網(wǎng)絡(luò),使用tcp ip協(xié)議作為高層協(xié)議;給出了影響數(shù)據(jù)傳輸實(shí)時(shí)性的各種因素,重點(diǎn)討論了ip協(xié)議棧性能優(yōu)化和減少網(wǎng)絡(luò)負(fù)荷的方法。
