Problems solved by technology

[0005] In view of the different wireless signals that can be received by different voyages during the ship's navigation process, currently ships can only manually try to receive wireless signals, and there is no detection method to detect whether the link is alive or not. The present invention proposes a ship navigation network system , the technical scheme adopted in the present invention is:

Embodiment 1

[0036] Such as figure 1 As shown, a ship navigation network system includes an industrial control processing unit, a GPS / attitude acquisition unit, a WIFI router, a wireless network card, a maritime satellite terminal, a private network wireless transmission unit, and a marine WIFI router hotspot;

[0037] The industrial control processing unit is electrically connected with the GPS / attitude acquisition unit, WIFI router, wireless network card, maritime satellite terminal, private network wireless transmission unit, and marine WIFI router hotspot respectively;

[0038] The WIFI router converts the mobile base station signal into a wired network signal and transmits it to the industrial control processing unit, and converts the data collected by the industrial control processing unit to the GPS / attitude acquisition unit into a wireless network signal and transmits it to the shore-based mobile base station;

[0039] The maritime satellite terminal is used to receive satellite si...

Embodiment 2

[0049] This embodiment provides a ship navigation network method, which is applied to the ship navigation network system provided above, and the specific steps are as follows:

[0050] S10. Perform network link survival detection. The industrial control processing unit uses different network link survival detection methods to determine the communication status of the ship's WIFI router, WIFI router, maritime satellite terminal, and private network wireless transmission unit according to whether the shipboard equipment is connected to the Internet. In case of disconnection, if the network link survives, enter S20;

[0051] S20. Real-time detection of network status based on the traffic detection method. If a link network is interrupted or idle, the network traffic is zero; the industrial control processing unit is based on the traffic conditions of the marine WIFI router, WIFI router, maritime satellite terminal, and private network wireless transmission unit. , and judge the n...

Embodiment 3

[0060] In the ship navigation network system provided by the present invention, the industrial control processing unit has a network routing learning function, and the positioning and attitude information of the ship navigation is collected according to the fixed navigation route of the ship, and combined with the four types of network link quality conditions in each voyage, it is determined to use the network. Type, the post-navigation can realize automatic network switching according to different navigation areas, no longer detect the quality of network links in real time, and reduce the burden of network transmission data. The system is fully automated, and can be judged and executed independently without manual participation. It can also realize manual positioning and self-selection to determine the working mode. Compared with the current full manual on-off and link quality judgment of each individual device network signal, it is more accurate and accurate. Scientific ratio...

Abstract

The invention provides a ship navigation network system. The ship navigation network system comprises an industrial control processing unit, a GPS / attitude acquisition unit, a WIFI router, a wirelessnetwork card, a maritime satellite terminal, a private network wireless transmission unit and a ship WIFI router hotspot. The industrial control processing unit is electrically connected with the GPS / attitude acquisition unit, the WIFI router, the wireless network card, the maritime satellite terminal, the private network wireless transmission unit and the marine WIFI router hot spot. Network linksurvival detection is adopted, network switching is carried out in the ship sailing process according to the principle that a free network is superior to a charging network and the high speed is superior to the low speed, and it is guaranteed that the ship uses the network signal with the highest speed, stable transmission and the best quality in the sailing process to achieve data communicationbetween the ship and the shore base.

Description

technical field [0001] The present invention relates to the field of ship wireless communication, and more specifically, to a ship navigation network system and an application method thereof. Background technique [0002] At present, the general WIFI signal has a coverage range ranging from a dozen meters to hundreds of meters according to the power of its signal transmitter. The 4G signal is based on the difference in building and user density. The coverage distance of a general community is 3 to 4 kilometers. Network communication equipment such as VHF radio stations are generally 50-100 kilometers away. Maritime satellites can achieve global coverage, and there is no communication distance limit. However, in most cases, the network speed is slow and the traffic fee is relatively expensive. [0003] International shipping ships depart from the port and wharf to the destination port wharf. During the voyage, due to the different coverage of various types of wireless network...
