Description

Technical Field

[0001] This invention relates to the field of VHF communication system technology, specifically to a VHF centralized control communication system and its working method. Background Technology

[0002] VHF (Very High Frequency) communication systems are the mainstream communication method for ships, supporting globally applicable distress rescue, navigational avoidance, and safety broadcasts, and are a key guarantee of 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" mode. The built-in sensors of the equipment only support local threshold alarms but lack remote data transmission capabilities. Maintenance personnel need to periodically carry instruments to the site to test key parameters to determine the operating status of the base station, resulting in low monitoring frequency. When anomalies occur at the base station, they cannot be dealt with in a timely manner, leading to communication abnormalities and delayed responses.

[0004] Ship radios have limited functionality and cannot provide additional features such as station broadcasts and waterway information warnings. With the increase in shipping routes and changes in route facilities, existing ship radios cannot meet the needs of users. Summary of the Invention

[0005] This invention provides a VHF centralized control communication system and its working method, which optimizes existing VHF communication system components to solve the above-mentioned problems.

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

[0007] A server cluster, which is communicatively connected to at least one VHF centralized control terminal, is used to manage the VHF centralized control terminal; process data uploaded by the VHF centralized control terminal; and transmit data to the VHF centralized control terminal.

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

[0009] The VHF broadcasting terminal broadcasts data based on data sent by the VHF central control terminal; and uploads data to the VHF central control terminal. The VHF broadcasting terminals are interconnected and used to forward data sent by the VHF central control terminal to the VHF broadcasting terminals connected in the communication.

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

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

[0012] Furthermore, the server cluster is used to perform communication establishment, voice monitoring, and voice broadcasting operations on the VHF broadcasting terminal based on the VHF broadcasting terminal data uploaded by the VHF centralized control terminal; and to record the monitoring process to form an audio file, and to perform playback of the audio file.

[0013] Furthermore, the server cluster is used to determine the status of the VHF centralized control terminal based on the data uploaded by the VHF centralized control terminal. When an abnormal status of the current VHF centralized control terminal is detected, the cluster controls the surrounding VHF centralized control terminals to perform functional replacement for the current VHF centralized control terminal.

[0014] Furthermore, the communication methods between the VHF central control terminal and the VHF broadcast terminal include VHF and / or AIS.

[0015] A method for operating a VHF centralized control and communication system includes: real-time monitoring of the status of the VHF centralized control terminal, handling abnormal VHF communication, and managing the VHF broadcast terminal.

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

[0017] Obtain parameters from the VHF centralized control terminal;

[0018] The parameters acquired from the VHF centralized control terminal are analyzed in real time.

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

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

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

[0022] At the same time, based on the normal coverage range of the abnormal VHF central control terminal, the parameters of the VHF central control terminal required to replace the abnormal VHF central control terminal are calculated, including the transmission power and location.

[0023] When using the second dynamic threshold to further determine if the VHF centralized control terminal is in an abnormal state;

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

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

[0026] The location of the ship equipped with the VHF broadcast terminal is determined based on the acquired VHF broadcast terminal data.

[0027] The corresponding voice data and / or text data are output to the VHF broadcast terminal according to the ship's position;

[0028] VHF broadcasting terminals output voice data and / or text data.

[0029] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0030] 1. It can identify the status of VHF centralized control terminals. When an anomaly is detected, other nearby VHF centralized control terminals can be used to cover the working range of the abnormal VHF centralized control terminal, thereby replacing its function and avoiding the impact on the VHF communication process after the anomaly occurs. Compared with the traditional VHF communication system, it can not only effectively monitor the status of the base station, but also respond quickly and avoid communication process anomalies.

[0031] 2. After obtaining the ship's position through the VHF broadcast terminal, corresponding text and / or voice information can be sent to the ship based on its position, providing navigation information during its voyage. Compared with existing ship radios, it better meets the usage needs.

Detailed Implementation

[0041] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, 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 this embodiment of the invention includes a server cluster 3, a VHF centralized control terminal 1, and a VHF broadcast terminal 2. The VHF broadcast terminal 2 is installed on a ship, and the VHF centralized control terminal 1 can be installed in a fixed or mobile manner. Fixed installation includes installation in a pontoon, tower enclosure, shore enclosure, or bridge pier enclosure, while mobile installation includes installation on a ship, such as a law enforcement vessel. The appropriate installation method can be selected according to the usage scenario.

[0043] Server cluster 3 is used for data processing. It is communicatively connected to at least one VHF central control terminal 1 for managing VHF central control terminal 1, processing data uploaded by VHF central control terminal 1, and transmitting data to VHF central control terminal 1.

[0044] Based on the coverage range of a single VHF central control terminal 1, multiple VHF central control terminals 1 can be used to cover different jurisdictions.

[0045] The deployment of the fixed VHF central control terminal 1 includes the following steps:

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

[0047] The initial layout of VHF central control terminal 1 is determined based on its signal coverage range and the structure of the watershed.

[0048] The number and location of VHF centralized control terminals 1 were calculated using simulation.

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

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

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

[0052] Among them, the Beidou positioning module a14 is used to obtain the location of the VHF central control terminal 1, and can use the Beidou system for simple information transmission. The communication module a12 is used to communicate with the ship using VHF or AIS, and also 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 central control terminal 1 and to display the broadcast area, channel, frequency, data refresh rate, area code, transmission power level, and volume. It can also be used to set the channel settings, power level settings, volume settings, data refresh frequency, domain name modification, working mode, and sampling rate. It should be noted that the above settings can be entered on the VHF central control terminal 1 using the touch screen a15, and can also be modified through the server cluster 3.

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

[0054] like Figure 1As shown, a VHF central control terminal 1 is communicatively connected to at least one VHF broadcast terminal 2. The communication methods between the VHF central control terminal 1 and the VHF broadcast terminal 2 include VHF and / or AIS. The advantage of using dual-channel communication is that AIS can be used as a temporary substitute when VHF communication is abnormal, for managing the VHF broadcast terminal 2; acquiring and processing data from the VHF broadcast terminal 2; transmitting data to the VHF broadcast terminal 2, which then broadcasts the data sent by the VHF central control terminal 1; and uploading data to the VHF central control terminal 1. The VHF broadcast terminals 2 are communicatively connected to each other and are used to forward data sent by the VHF central control terminal 1 to the VHF broadcast terminals 2 with which they are communicatively connected.

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

[0056] The control module b21 communicates with the radio host 22 and is used to control 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 central control terminal 1 in VHF and / or AIS. The communication module a12 of the VHF central control terminal 1 communicates with the communication module b24 of the VHF broadcast terminal 2. The communication module b24 of the VHF broadcast terminal 2 also communicates with the communication module b24 of the VHF broadcast terminal 2 within the signal range and is used to forward the information sent by the server cluster 3.

[0057] Server cluster 3 is used to perform communication establishment, voice monitoring, and voice broadcasting operations on VHF broadcasting terminal 2 based on the data uploaded by VHF central control terminal 1; and to record the monitoring process to form an audio file, and to perform playback of the audio file.

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

[0059] Server cluster 3 is used to determine the status of VHF centralized control terminal 1 based on the data uploaded by VHF centralized control terminal 1. When an abnormal status of the current VHF centralized control terminal 1 is detected, it controls the surrounding VHF centralized control terminals 1 to perform functional replacement for the current VHF centralized control terminal 1.

[0060] A method for operating a VHF centralized control communication system, comprising:

[0061] 1. Monitor the status of VHF centralized control terminal 1 in real time.

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

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

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

[0065] S12, determine the real-time status of VHF centralized control terminal 1 based on the set first dynamic threshold.

[0066] 2. Handle abnormal VHF communication.

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

[0068] S20, when the first dynamic threshold is used to determine that the VHF central control terminal 1 is in an abnormal state, the state of the VHF central control terminal 1 is further determined using the set second dynamic threshold.

[0069] S21, At the same time, based on the normal coverage range of the abnormal VHF central control terminal 1, the parameters of the VHF central control terminal 1 required to replace the abnormal VHF central control terminal 1 are calculated, including the transmission power and location.

[0070] S22, when further determining the abnormal status of VHF centralized control terminal 1 using the second dynamic threshold;

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

[0072] The first dynamic threshold and the second dynamic threshold are set according to actual conditions. The first dynamic threshold is used for initial warning. After an anomaly is identified using the first dynamic threshold, the second dynamic threshold is used for further identification. After an anomaly is identified using the second dynamic threshold, the VHF central control terminal 1 is in a state where it cannot operate normally. At this time, it is necessary to replace the abnormal VHF central control terminal 1 with a function based on the calculated replacement VHF central control terminal 1 position and transmission power. This can prevent communication problems caused by the abnormality of VHF central control terminal 1.

[0073] Meanwhile, when using VHF centralized control terminal 1 to replace the faulty VHF centralized control terminal 1, VHF broadcast terminal 2 can also be used to forward communications, thereby expanding the coverage of the replacement VHF centralized control terminal 1 and further ensuring communication. After the VHF centralized control terminal 1 is repaired, normal communication will be restored.

[0074] 3. Manage VHF broadcast terminal 2.

[0075] Managing VHF broadcast terminal 2 includes the following steps:

[0076] S30, determine the location of the ship equipped with VHF broadcast terminal 2 based on the acquired data from VHF broadcast terminal 2;

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

[0078] S32, VHF broadcast terminal 2 outputs voice data and / or text data.
