Underwater remote control communication network

Abstract

The invention provides an underwater remote control communication network. The underwater remote control communication network comprises an overwater network and an underwater network, a plurality of independent first ring nets are formed by each overwater controller and two overwater exchangers, a plurality of independent first ring nets are formed by each underwater controller and two underwater exchangers, second ring nets are formed by overwater and underwater exchangers and overwater and underwater optical transceivers, the whole network is in a multi-net crossed network structure which is formed by the second ring nets and the plurality of parallel first ring nets which are established on the second ring nets, all control devices and network links in the network are copied, the network redundancy degree and the fault tolerance are high, the first ring nets can be expanded on the second ring nets at will, the network expandability is high, the forming of a distributed control system with high reliability is facilitated, and the whole network is clear in structure, reasonable in design, low in costs and particularly suitable for signal transmission of an underwater remote control device.

Description

technical field [0001] The invention relates to an underwater remote control communication network, in particular to an underwater remote control communication network with high redundancy and scalability, and belongs to the technical field of communication. Background technique [0002] The underwater operation environment is complex, and the nonlinearity, time-varying and cross-coupling of the operating equipment are very serious. For the cooperative work of various control components, especially the real-time performance, stability, reliability and redundancy of information transmission, etc. Therefore, the stability and reliability of the communication network is the key to underwater operations. Due to the large network area, long network links, and harsh underwater environment, the underwater communication network is more prone to damage and difficult to maintain. Therefore, compared with the ground network structure, it requires higher reliability of the network syste...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the defects of the existing underwater communication network such as low redundancy and fault tolerance, poor scalability, inconvenient formation of a highly reliable distributed control network, and high hardware cost, and provide an underwater communication network Under the remote control communication network, all control devices and network links in the network are backed up, and the network redundancy and fault tolerance are very high. The entire network consists of the second ring network and several parallel first ring networks established on the second ring network. The ring network constitutes a multi-network cross network structure. The network has strong scalability and is conducive to the formation of a highly reliable distributed control system. The entire network structure is clear, the design is reasonable, and the cost is low.
