An automatic optimization method of communication equipment suitable for integrated communication of ships

Abstract

The communication equipment automatic optimization method suitable for ship integrated communication disclosed by the present invention first establishes the three communication equipments of medium and high frequency radio stations, very high frequency radio stations and satellite communication terminals in three aspects: communication cost, communication establishment time and communication distance Based on the performance evaluation scale, three user demand models are constructed based on the performance evaluation results, namely cost optimization model, time optimization model and cost-time balance optimization model. Time plan and conventional path plan; when a ship initiates communication, the user enters the MMSI code of the other ship, and selects a communication equipment optimization plan according to the demand; finally, according to the selected communication equipment optimization plan, the communication equipment optimization process is started, and the best one is automatically selected. communication device, use the preferred device to start communication. The invention can greatly reduce the operation complexity of the ship communication equipment, and effectively improve the communication success rate and reliability.

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
