Abstract:Concerning how to build an all-domain communication infrastructure and deep integration of various machines with remote and ultra-remote control based on fifth-generation fixed network (F5G) technology application in ports,we conduct research on the application of F5G network architecture and communication infrastructure in Luojing port area in Shanghai Port.By analyzing the characteristics of remote control operations in the port and the method of designing different business application schemes in a classified manner,we obtain the results that the construction of an F5G passive simple network architecture and an ultra-remote fully optical ring network communication infrastructure can ensure the real-time communication of control signals from three different programmable logic controller (PLC) systems,namely Chuanfeng,ABB,and TMEIC in entire port area.Meanwhile,the three-location fully optical ring network can meet the requirements of large bandwidth,massive connectivity,low latency,and zero packet loss for three ultra-remote control centers.The classified design of remote control operations based on F5G technology can provide stable remote control data transmission links for 14 quay cranes and 31 rail-mounted gantry cranes.The results offer theoretical support for the integrated collaborative operation of multiple machines and applications,and has significant reference value for promoting the normal automation of all-domain machinery in port areas,the establishment of ultra-remote control centers.
