Shipborne communication network switching control method and controller

Abstract

The invention discloses a shipborne communication network switching control method and a controller. The method comprises the following steps: S1, detecting network quality indexes of a first communication network and a second communication network, and determining the network quality of the first communication network and the second communication network according to the detected network quality indexes; and S2, determining a signal quality coefficient of a corresponding communication network according to the communication quality judgment result of the first communication network and the second communication network and the network quality index, and selecting a corresponding outlet network as the currently used optimal network through load balancing, thereby ensuring the communication quality of the network on the ship.

Description

technical field [0001] The invention relates to the technical field of ship communication, in particular to a method and a controller for switching control of a shipborne communication network. Background technique [0002] With the development of offshore fishery, the effectiveness and stability of offshore communications have become a rigid need for maritime communications. The development and changes of offshore fishery have put forward higher requirements for maritime satellite communication and its related supporting facilities and applications. [0003] For offshore fishing vessels and other types of offshore vessels, in view of the needs of navigation safety, the needs of official communications, and the needs of personnel working on ships to communicate and communicate with other ships and shore terminals in a timely manner, the use of satellite communication has become a rigid need for offshore operations. , especially the official communication requirements are st...

Problems solved by technology

[0005] 1. The scheme involves many hardware devices and the layout and wiring and configuration of each device are complex;

[0006] 2. Although the smart gateway supports multi-type network switching control, it can only be used for the switching of various home networks and land 4G environments on land, and is not suitable for satellite networks at sea and 4G environments by the sea.

At present, the intelligent gateway can only select the export network according to whether each connected WAN port has a network, so as to intelligently allocate the subsequent Internet devices to select the export network, and the satellite network at sea may have environmental factors such as antenna occlusion, resulting in poor network or signal None, and the seaside 4G signal may have factors such as the distance between 4G equipment and the 4G base station, resulting in poor network or no signal, so there are serious disadvantages in directly switching the WAN port connected to the smart gateway to allocate VSAT or 4G network: for example , the VSAT signal is available and good, and the 4G signal is available and good. At this time, it is normal for the intelligent gateway to go to any link after the distribution. However, if the VSAT signal is weak due to occlusion, and the 4G signal is available and good. The gateway can only know that the two network links are available. Some post-level personnel use the VSAT network, and some use the 4G network. In this way, users who use the VSAT network will experience a poor network; similarly, if the VSAT signal is available and good , The 4G signal is strong and sometimes weak near the coast due to the ship going out to sea. At this time, the smart gateway judges that the two WAN port links are also connected, and will still arrange some people in the later stage to use the VSAT network and some people to use the 4G network. As a result, the user experience of the 4G network is poor
