Technical Field

[0001] The present invention relates to the technical field of ship communication management, and in particular to a Beidou-based VHF centralized management system. Background Art

[0002] Very high frequency (VHF) communication technology has long been responsible for core functions such as ship navigation safety communications, distress calls, and port and shipping dispatch and command in the Yangtze River mainline shipping field. The line-of-sight propagation advantage given by its 30-300MHz frequency band characteristics makes it particularly suitable for the short-range communication coverage needs in the complex terrain environment along the Yangtze River. However, the traditional VHF communication system is limited to the one-way voice communication mode. It lacks effective management of the ship radio communication process, resulting in the inability to optimize the overall communication resource allocation based on real-time communication status. It is also difficult to achieve a systematic improvement in ship management efficiency, which restricts the technical support capabilities for the development of intelligent shipping. Summary of the Invention

[0003] The embodiment of the present invention provides a Beidou-based VHF centralized management system, which can manage the VHF communication process, improve the intelligence level of the traditional VHF communication system, and improve the VHF communication quality.

[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] like Figure 1 As shown, the present invention constructs a Beidou-based VHF centralized management system, including:

[0030] The management module 1 is configured to manage the VHF communication process; and monitor the status of the centralized control terminal 3.

[0031] The management module 1 includes a VHF centralized control platform 11 and a data resource management platform 12 .

[0032] The VHF centralized control platform 11 is used for centralized control and management of VHF communications, including voice monitoring, communication establishment, voice broadcasting and recording backtracking.

[0033] The process of establishing communication includes: after the ship radio station 5 initiates a communication request, the VHF centralized control platform 11 connects the target ship radio station 5 with the requesting ship radio station 5 according to the target requested by the ship radio station 5. During this communication process, the VHF centralized control platform 11 also monitors the voice of the communication process and records it to form a recording file for easy recording backtracking.

[0034] The VHF centralized control platform 11 is connected to at least one user terminal a7, which is used to manage the VHF centralized control platform 11, such as controlling communication establishment, monitoring the communication process, and performing voice broadcasting and recording back.

[0035] It should be noted that when the user terminal a7 does not execute the control command, the VHF centralized control platform 11 automatically performs tasks such as voice monitoring, communication establishment, and voice broadcasting on the VHF communication process, and recording backtracking needs to be executed according to the initiation of the user terminal a7.

[0036] The data resource management platform 12 is used to manage and control the device status of the centralized control terminal 3, including terminal operation status, network status, device storage usage, and recording file statistics.

[0037] The data resource management platform 12 is connected to at least one user terminal b8, which is used to manage the data resource management platform 12, including checking the terminal operation status, network status, device storage occupancy, and recording file statistics. When the user terminal b8 does not execute the control instruction, the data resource management platform 12 automatically obtains the terminal operation status, network status, device storage occupancy, and recording file statistics.

[0038] The data resource management platform 12 is also used to obtain the route trajectory of the ship, and, according to the time node, add the data generated by the VHF communication at the corresponding position of the route trajectory to form a trajectory communication data link.

[0039] During operation, each ship forms a unique route track according to its route. The length of the route track is divided according to the set length, such as the set route time or sailing mileage. After reaching the set route time or sailing mileage, the current route track is stored and the route track is recorded again with the current node as the starting point. There is an identifier between the end point and the starting point of different route tracks to identify two adjacent route tracks, which can realize the merging of route tracks and achieve full life cycle management of ship routes.

[0040] After obtaining the ship's route trajectory, according to the time node, when the ship initiates or receives VHF communication, the obtained recording files are merged into the ship's route trajectory according to the time node to form a trajectory communication data link. Different trajectory communication data links can be connected and merged through the identifiers of the route trajectory end point and starting point.

[0041] The management module 1 manages the VHF communication process and further includes identifying the VHF communication abnormal area and restoring the VHF communication abnormal area. The restoration of the VHF communication abnormal area includes temporary restoration or permanent restoration.

[0042] The process of identifying VHF communication abnormal areas includes:

[0043] 1. Obtain the communication quality indicators, equipment status and environmental data of ship radio station 5;

[0044] Communication quality indicators include: signal-to-noise ratio (SNR), bit error rate (BER), and signal strength index (RSSI).

[0045] Device status includes: antenna voltage, transmit power, and device temperature.

[0046] Environmental data includes: terrain data, changes in hydrological conditions, and locations of electromagnetic interference sources.

[0047] Determine whether there is any abnormality in the VHF communication process signal based on the acquired data.

[0048] 2. When an anomaly is identified, the DBSCAN algorithm is used to determine the boundaries of the signal anomaly area and the cause of the anomaly based on the ship's position.

[0049] When it is identified that the cause of the abnormality is due to the terrain or a failure of the centralized control terminal 3, a permanent restoration method is adopted to restore the signal of the abnormal area. Among them, the permanent restoration method adopts a method of adding a centralized control terminal 3 to provide permanent signal coverage for the abnormal area.

[0050] When it is identified that the cause of the anomaly is temporary, such as changes in hydrological conditions or temporary electromagnetic interference sources, a temporary recovery method is used to restore the signal in the abnormal area based on the boundary of the identified abnormal area. Among them, temporary recovery uses signal relay to achieve temporary signal coverage of the communication abnormal area.

[0051] Among them, signal relay uses drone swarms or unmanned ship swarms to provide temporary signal coverage to the communication abnormality area to achieve temporary recovery. The drone swarms or unmanned ship swarms are equipped with relay communication modules for signal relay, which includes the following process:

[0052] Relay device coverage model

[0053] Optimal deployment location:

[0054] Divide the coverage area of relay equipment based on Voronoi diagram to minimize signal blind spots;

[0055] Objective function:

[0056]

[0057] Where u j : The location of the relay device, s k :The position of the ship to be covered, C j : The collection of ships that the relay is responsible for.

[0058] Energy Management and Relay Strategy:

[0059] Remaining battery life prediction:

[0060]

[0061] Where, E current :Current power, E fly (d): Return energy consumption, P hover Power consumption fixed at the current position, P com : Communication module power consumption.

[0062] Relay scheduling rules:

[0063] Trigger condition: T remain When it is less than the set threshold, the relay is started.

[0064] Relay strategy: Select the nearest relay device with sufficient power to take over.

[0065] During the above-mentioned relay process, the drone cluster or unmanned ship cluster enters the set position in turn and remains at the set position under the dispatch of the management module 1. After it is determined that the temporary signal abnormality area disappears, all drone clusters or unmanned ship clusters are dispatched to return. When the abnormal area persists, the drones or unmanned ships are controlled to perform relay relay according to the relay dispatch rules. After the energy consumption of the current relay device reaches the threshold, the relay device with the nearest distance and sufficient power is dispatched to replace the current relay device, and at the same time the current relay device is controlled to return for energy replenishment.

[0066] The server cluster module 2 is configured to process system data and communication requests; and to store data.

[0067] The centralized control terminal 3 is connected to at least one ship radio station 5 for communication, and is used to obtain the communication data of the ship radio station 5 and upload it to the server cluster module 2; and receive the data sent by the server cluster module 2 and transmit it to the ship radio station 5; and monitor the working status of the ship radio station 5. The centralized control terminal 3 is composed of a Beidou positioning module, a VHF communication module, and an Android smart platform, and is mainly used as a VHF base station along the Yangtze River.

[0068] Among them, the centralized control terminal 3 is connected to the VHF communication antenna feed line system 6, and uses the VHF communication antenna feed line system 6 to transmit and receive VHF signals. The centralized control terminal 3 communicates with the ship radio station 5 through the VHF communication antenna feed line system 6.

[0069] The transmission network module 4 includes 4G and wired Ethernet, which is used to build a data transmission channel suitable for real-time communication and data exchange between the above modules and terminals.

[0070] The present invention proposes a Beidou-based VHF centralized management system, which utilizes a centralized control terminal 3 to connect multiple ship radio stations 5 within the communication range. It can not only obtain the working status of the ship radio station 5, but also upload the communication data of the ship radio station 5 to the server cluster module 2, thereby realizing functions such as voice monitoring, communication establishment, voice broadcasting and recording backtracking. At the same time, it can also forward the data received from the server cluster module 2 to the ship radio station 5, thereby realizing the transmission of multiple information and effectively improving the intelligence level of the traditional VHF communication system. On the other hand, it can also identify the abnormal VHF communication area of the ship radio station 5, and restore the communication according to the abnormality, thereby improving the VHF communication quality.
