摘要
文章研究了基于电压差包络线的港船接岸电智能无线信息控制装置。无线信息装置根据船电与岸电电压、频率、相位的不同形成电压差包络线,检测包络线最低点控制合闸,以完成船电与岸电无冲击电流的无缝连接,从而提高船舶接岸电的时效性,实现船舶节能和港口环保。利用无线扩频技术LoRa进行无线传输,通过船舶无线模块和岸上无线模块之间的信号传输与协同工作,使船舶靠泊后能够快速方便地接岸电,这对于提高船舶靠泊后接岸电的操作效率和缩短船舶靠港时间有很大的帮助。
Wireless control seamless connection shore power device based on voltage difference envelope line is studied.According to the different voltage,frequency and phase between ship power and shore power,the wireless information device forms the envelope line of voltage difference,detects the lowest point of the envelope line and controls the switch on,so as to complete the seamless connection of ship power and shore power without impact current,improving the timeliness of ship shore power connection,realizing ship energy conservation and port environmental protection.Through the wireless spread spectrum technology LoRa as wireless transmission,through the signal transmission and cooperation between the ship's wireless module and the shore's wireless module,it can connect with shore power quickly and correctly after the ship touches the shore,which is helpful to improve the operation efficiency of the ship's shore power and shorten the time of the ship's berthing.
