THE CONCEPT OF BUILDING A TELECOMMUNICATIONS SUBSYSTEM OF A REMOTELY PILOTED SEA TUG

Abstract

The article presents the concept of building an effective telecommunications subsystem for a remotely piloted sea tug operating in the area of responsibility of a local vessel traffic control system. This concept, in turn, was developed within the framework of the concept of unmanned navigation being created in the Russian Federation, called the A-navigation concept. The work was carried out using an engineering-cybernetic approach to the design of complex systems. According to this approach, the projected subsystem is considered not in isolation, but as part of a complex hierarchical system, at the upper level of which the concept of a metasystem is introduced, which in relation to the telecommunications subsystem is a local ship traffic control system. The goals and objectives of the local vessel traffic control system are considered and the requirements for a remote-controlled tugboat and its telecommunications subsystem are determined. The main stages of operation of the remotely piloted tug are determined. The operations carried out within the framework of the functions of the telecommunications subsystem included in the studied system of this tug are identified and investigated. Along with the functional requirements, the most important requirements are the absence of interference to the existing radio channels of the vessel traffic control system from the telecommunications subsystem and the provision of a cybersecurity regime to exclude unauthorized interference in the management of the tugboat. The scheme of automatic authentication of the operator and his remotely piloted tug is presented. The optimal structure of the telecommunications subsystem is determined, recommendations are presented on the choice of control channels, telemetry and visualization, as well as on the choice of protocols for its ship and shore local networks. The problem of creating a reliable visualization radio channel is considered and ways to solve it are proposed.
