Communication equipment automatic optimization method suitable for ship integrated communication

Abstract

The invention discloses a communication equipment automatic optimization method suitable for ship integrated communication. The method comprises the following steps: firstly, respectively establishingperformance evaluation scales of three communication equipment, namely a medium-high frequency radio station, a very-high frequency radio station and a satellite communication terminal, in three aspects of communication cost, communication establishment time and communication distance; constructing three user demand models, namely a cost optimization model, a time optimization model and a cost and time balance optimization model, on the basis of a performance evaluation result, and correspondingly proposing three communication equipment optimization schemes, namely, a least-expense scheme, afastest-time scheme and a conventional path scheme; when the ship initiates communication, a user inputting an MMSI code of an opposite ship, and selecting a communication equipment optimization scheme according to requirements; and finally, starting a communication equipment optimization flow according to the selected communication equipment optimization scheme, automatically optimizing the optimal communication equipment, and starting communication by utilizing the optimized equipment. The operation complexity of ship communication equipment can be greatly reduced, and the communication success rate and reliability are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of ocean ship integrated communication, and in particular relates to an automatic optimization method for communication equipment suitable for ship integrated communication. Background technique [0002] At present, there are three main means of marine ship communication: medium and high frequency radio stations, very high frequency radio stations and satellite communication terminals. Among them, the medium-high frequency radio and the very high frequency radio are important components of the Global Maritime Distress and Safety System (GMDSS). According to the requirements of GMDSS, ships traveling in the sea area above A2 must be equipped with medium-high frequency radios and very high frequency radios. [0003] At present, the main communication means of marine ship satellite communication include: Inmarsat, Beidou, Tiantong-1, Iridium, Eurostar, VSAT, etc. Among them, Inmarsat and Beidou are the most wid...

AI Technical Summary

Problems solved by technology

[0004] The above three ship communication methods have their own advantages and disadvantages. The medium and high frequency radio stations are suitable for short-, medium- and long-distance communications. The equipment has no communication expenses, and is suitable for harsh environments such as heavy rain and shelter. It has high environmental adaptability, but the communication success rate is the lowest. Long time; VHF radio is suitable for short-distance communication, the equipment has no communication expenses, and the communication success rate is high, the environment adaptability is the highest, the communication establishment time is short, but the communication distance is short, and only supports line-of-sight communication; satellite communication is suitable For near-medium and long-distance communication, the communication success rate is the highest, and the communication establishment time is the shortest, but the equipment is easily affected by harsh environments such as heavy rain and occlusion, the environmental adaptability is low, and the equipment communication costs are high. Take the satellite mobile communication terminal as an example, its use fee is calculated by traffic, generally 1~1.5 yuan / MB, equivalent to 0.5~0.75 yuan / minute for satellite phone
