Description

Technical Field

[0001] The present invention relates to the technical field of VHF communication systems, and in particular to a VHF centralized control communication system and a working method thereof. Background Art

[0002] VHF (very high frequency) communication systems are the mainstream communication method for ships. They support global distress rescue, navigation avoidance, and safety broadcasts, and are a key guarantee for maritime safety. However, existing systems have the following problems:

[0003] Base station fault monitoring relies on manual labor. Traditional VHF base stations use a "single-unit + manual inspection" model. The built-in sensors in the devices only support local threshold alarms but lack remote data transmission capabilities. Operations and maintenance personnel must regularly bring instruments to the site to test key parameters to determine the base station's operating status. This results in infrequent monitoring and a delay in timely processing when base station anomalies occur, leading to communication anomalies and delayed responses.

[0004] The functions of ship radio stations are relatively simple and cannot provide more functions, such as station broadcasts and water information warnings. With the increase in routes and changes in route facilities, existing ship radio stations cannot meet usage needs. Summary of the Invention

[0005] The embodiment of the present invention provides a VHF centralized control communication system and a working method thereof, which optimizes the existing VHF communication system components to solve the above-mentioned problems.

[0006] A VHF centralized control communication system, comprising:

[0007] A server cluster is connected to at least one VHF centralized control terminal for managing the VHF centralized control terminal, processing data uploaded by the VHF centralized control terminal, and transmitting data to the VHF centralized control terminal;

[0008] A VHF centralized control terminal is communicatively connected to at least one VHF broadcast terminal for managing the VHF broadcast terminal, acquiring data from the VHF broadcast terminal for processing, and transmitting data to the VHF broadcast terminal;

[0009] The VHF broadcast terminal broadcasts according to the data sent by the VHF centralized control terminal; and uploads data to the VHF centralized control terminal, wherein the VHF broadcast terminals are communicatively connected to each other for forwarding the data sent by the VHF centralized control terminal to the communicatively connected VHF broadcast terminal.

[0010] Furthermore, the VHF centralized control terminal includes a control module a, which is respectively communicatively connected to the Beidou positioning module a, the communication module a and the touch display screen a. The VHF centralized control terminal also includes a power supply module a for powering the VHF centralized control terminal.

[0011] Furthermore, the VHF broadcast terminal includes a control module b, which is communicatively connected to the radio host, touch screen b, Beidou positioning module b and communication module b. The VHF broadcast terminal also includes a power module b, which is used to power the VHF broadcast terminal.

[0012] Furthermore, the server cluster is used to perform communication establishment, voice monitoring, and voice broadcast operations on the VHF broadcast terminal according to the VHF broadcast terminal data uploaded by the VHF centralized control terminal; and record the monitoring process to form a recording file, and perform backtracking of the recording file.

[0013] Furthermore, the server cluster is used to judge the status of the VHF centralized control terminal based on the data uploaded by the VHF centralized control terminal. When it is identified that the status of the current VHF centralized control terminal is abnormal, the server cluster controls the surrounding VHF centralized control terminals to replace the current VHF centralized control terminal.

[0014] Furthermore, the communication method between the VHF centralized control terminal and the VHF broadcast terminal includes VHF and / or AIS.

[0015] A VHF centralized control communication system working method includes: real-time monitoring of VHF centralized control terminal status, processing abnormal VHF communications, and managing VHF broadcast terminals.

[0016] Furthermore, the status monitoring of the VHF centralized control terminal includes the following steps:

[0017] Get the parameters of the VHF centralized control terminal;

[0018] Conduct real-time analysis of the acquired VHF centralized control terminal parameters;

[0019] The real-time status of the VHF centralized control terminal is determined according to the set first dynamic threshold.

[0020] Furthermore, the process of handling abnormal VHF communications includes the following steps:

[0021] When the first dynamic threshold is used to determine that the VHF centralized control terminal state is abnormal, the set second dynamic threshold is used to further determine the VHF centralized control terminal state;

[0022] At the same time, according to the normal coverage range of the abnormal VHF centralized control terminal, the parameters of the VHF centralized control terminal required to replace the abnormal VHF centralized control terminal are calculated, including the transmission power and position;

[0023] When the second dynamic threshold is used to further determine that the VHF centralized control terminal is abnormal;

[0024] The obtained parameters are used to control the operation of the corresponding VHF centralized control terminal and take over the operation of the abnormal VHF centralized control terminal.

[0025] Furthermore, managing the VHF broadcast terminal includes the following steps:

[0026] Determine the position of the ship equipped with the VHF broadcast terminal based on the acquired VHF broadcast terminal data;

[0027] Output corresponding voice data and / or text data to the VHF broadcast terminal according to the position of the ship;

[0028] The VHF broadcast terminal outputs voice data and / or text data.

[0029] The beneficial effects of the above technical solutions provided by the embodiments of the present invention include at least:

[0030] 1. It can identify the status of the VHF centralized control terminal. When it is identified that there is an abnormality, other VHF centralized control terminals in the surrounding area can be used to cover the working range of the abnormal VHF centralized control terminal to replace its function and avoid the impact on the VHF communication process due to the abnormality. Compared with the traditional VHF communication system, it can not only effectively monitor the status of the base station, but also respond quickly to avoid abnormalities in the communication process.

[0031] 2. After obtaining the position of the ship through the VHF broadcast terminal, the corresponding text and / or voice information can be sent to the ship according to the position of the ship, and navigation information can be provided during the navigation process, which can better meet the use needs compared with the existing ship radio.

[0041] The 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. Instead, these embodiments are provided to enable a more thorough understanding of the present disclosure.

[0042] like Figure 1 As shown, the structure of the VHF centralized control communication system disclosed in the embodiment of the present invention includes a server cluster 3, a VHF centralized control terminal 1 and a VHF broadcast terminal 2, wherein the VHF broadcast terminal 2 is installed on a ship, and the VHF centralized control terminal 1 can be fixedly installed or mobilely installed, wherein the fixed installation includes installation on a pontoon, a tower chassis, a shore chassis or a pier chassis, and the mobile installation includes installation on a ship, such as a law enforcement ship, etc. The appropriate installation method can be selected according to the usage scenario.

[0043] The server cluster 3 is used for processing data, and is in communication connection with at least one VHF centralized control terminal 1, for managing the VHF centralized control terminal 1; and processing data uploaded by the VHF centralized control terminal 1; and transmitting data to the VHF centralized control terminal 1.

[0044] According to the coverage of a single VHF centralized control terminal 1, multiple VHF centralized control terminals 1 can be used in different jurisdictions to complete the coverage of the jurisdiction.

[0045] The layout of the fixed installation VHF centralized control terminal 1 includes the following steps:

[0046] Construct a corresponding model based on the structure of the watershed;

[0047] Arrange the initial layout of VHF centralized control terminal 1 according to the signal coverage of VHF centralized control terminal 1 and the structure of the watershed;

[0048] The number and location of the VHF centralized control terminals 1 are calculated by simulation.

[0049] The location of the VHF centralized control terminal 1 satisfies that, when one of the VHF centralized control terminals 1 fails, at least two adjacent VHF centralized control terminals 1 can cover the coverage range of the failed centralized control terminal after increasing their power.

[0050] There are no special requirements for the mobile installation of the VHF centralized control terminal 1, which is generally used by law enforcement ships to manage ships on the route.

[0051] like Figure 1 As shown, the VHF centralized control terminal 1 includes a control module a11, which is respectively communicatively connected to the Beidou positioning module a14, the communication module a12 and the touch display screen a15. The VHF centralized control terminal 1 also includes a power supply module a13 for powering the VHF centralized control terminal 1.

[0052] Among them, the Beidou positioning module a14 is used to obtain the position of the VHF centralized control terminal 1, and the Beidou system can be used for simple information transmission. The communication module a12 is used to communicate with the ship using VHF or AIS, and is also used to communicate with the server cluster 3 using Ethernet or cellular data network. The touch screen a15 is used to display the operating status of the VHF centralized control terminal 1 and to display the broadcast area, channel, frequency, data refresh rate, area code, transmission power level, and volume data. Channel setting, power level setting, volume setting, data refresh frequency, domain name modification, working mode, and sampling rate operation settings. It should be noted that the above settings can be completed by inputting into the VHF centralized control terminal 1 using the touch screen a15, and the above settings can also be modified through the server cluster 3.

[0053] The power module a13 can be powered by mains electricity or solar energy.

[0054] like Figure 1As shown, a VHF centralized control terminal 1 is communicatively connected to at least one VHF broadcast terminal 2. The communication method between the VHF centralized control terminal 1 and the VHF broadcast terminal 2 includes VHF and / or AIS. The advantage of using two-way communication is that when the VHF communication is abnormal, AIS can be used to temporarily replace it for managing the VHF broadcast terminal 2; and, data from the VHF broadcast terminal 2 is obtained for processing; and, data is transmitted to the VHF broadcast terminal 2, and the VHF broadcast terminal 2 broadcasts according to the data sent by the VHF centralized control terminal 1; and, data is uploaded to the VHF centralized control terminal 1, wherein the VHF broadcast terminals 2 are communicatively connected to each other and are used to forward data sent by the VHF centralized control terminal 1 to the VHF broadcast terminal 2 with the communication connection.

[0055] Specifically, the VHF broadcast terminal 2 includes a control module b21, which is communicatively connected to the radio host 22, the touch screen b23, the Beidou positioning module b26 and the communication module b24. The VHF broadcast terminal 2 also includes a power module b25, which is used to power the VHF broadcast terminal 2.

[0056] The control module b21 is communicatively connected to the radio host 22 for controlling the radio host 22. The touch screen b23 is used to display the status of the VHF broadcast terminal 2 and display text information. The Beidou positioning module b26 is used to obtain the current position of the ship. The communication module b24 is used to communicate with the VHF centralized control terminal 1 in VHF and / or AIS mode. The communication module a12 of the VHF centralized control terminal 1 is communicatively connected to the communication module b24 of the VHF broadcast terminal 2. The communication module b24 of the VHF broadcast terminal 2 is also communicatively connected to the communication module b24 of the VHF broadcast terminal 2 within the signal range for forwarding information sent by the server cluster 3.

[0057] The server cluster 3 is used to perform communication establishment, voice monitoring, and voice broadcast operations on the VHF broadcast terminal 2 according to the VHF broadcast terminal 2 data uploaded by the VHF centralized control terminal 1; as well as record the monitoring process to form a recording file, and perform backtracking of the recording file.

[0058] When a VHF broadcast terminal 2 requests another VHF broadcast terminal 2 to communicate, the server cluster 3 connects the two VHF broadcast terminals 2 according to the request uploaded by the VHF centralized control terminal 1. During the communication process, the server cluster 3 automatically monitors the communication process and records it to form a recording file. The recording file can also be searched and traced back in the subsequent process.

[0059] The server cluster 3 is used to judge the status of the VHF centralized control terminal 1 based on the data uploaded by the VHF centralized control terminal 1. When it is identified that the status of the current VHF centralized control terminal 1 is abnormal, the server cluster 3 controls the surrounding VHF centralized control terminals 1 to replace the current VHF centralized control terminal 1 with its functions.

[0060] A VHF centralized control communication system working method, comprising:

[0061] 1. Real-time monitoring of the status of VHF centralized control terminal 1.

[0062] Among them, the status monitoring of the VHF centralized control terminal 1 includes the following steps:

[0063] S10, obtaining parameters of VHF centralized control terminal 1;

[0064] S11, performing real-time analysis on the acquired parameters of the VHF centralized control terminal 1;

[0065] S12: judging the real-time status of the VHF centralized control terminal 1 according to the set first dynamic threshold.

[0066] 2. Handle abnormal VHF communications.

[0067] The process of handling abnormal VHF communications includes the following steps:

[0068] S20, when the first dynamic threshold is used to determine that the state of the VHF centralized control terminal 1 is abnormal, the set second dynamic threshold is used to further determine the state of the VHF centralized control terminal 1;

[0069] S21, at the same time, according to the normal coverage range of the abnormal VHF centralized control terminal 1, the parameters of the VHF centralized control terminal 1 required to replace the abnormal VHF centralized control terminal 1 are calculated, including the transmission power and the position;

[0070] S22, when the second dynamic threshold is used to further determine that the VHF centralized control terminal 1 is in an abnormal state;

[0071] S23, using the obtained parameters to control the operation of the corresponding VHF centralized control terminal 1, and taking over the operation of the abnormal VHF centralized control terminal 1.

[0072] The above-mentioned first dynamic threshold and second dynamic threshold are set according to actual conditions, wherein the first dynamic threshold is used for primary warning. After the first dynamic threshold is used to identify the presence of an abnormality, the second dynamic threshold is used for further identification. After the second dynamic threshold is used to identify the presence of an abnormality, the status of the VHF centralized control terminal 1 is that it cannot operate normally. At this time, it is necessary to replace the abnormal VHF centralized control terminal 1 with a functional replacement based on the calculated replacement position and transmission power of the VHF centralized control terminal 1, so as to avoid problems in the communication process caused by the abnormality of the VHF centralized control terminal 1.

[0073] At the same time, when the VHF centralized control terminal 1 is used to replace the abnormal VHF centralized control terminal 1, the VHF broadcast terminal 2 can also be used to forward communications, so as to expand the coverage of the replacement VHF centralized control terminal 1, further ensure communication, and restore normal communication after the VHF centralized control terminal 1 is repaired.

[0074] 3. Manage VHF broadcast terminal 2.

[0075] Wherein, managing the VHF broadcast terminal 2 includes the following steps:

[0077] S31, outputting corresponding voice data and / or text data to the VHF broadcast terminal 2 according to the position of the ship;
