Description

Technical Field

[0001] This utility model belongs to the field of wireless communication system technology, and specifically relates to a maritime long-distance interactive communication system. Background Technology

[0002] With the development of the marine economy, offshore operations (such as fishing, transportation, scientific research, and oil and gas platforms) are becoming increasingly frequent. Reliable long-distance communication is crucial for ensuring the safety of personnel at sea, achieving operational coordination, and facilitating data transmission. Currently, maritime communication mainly relies on traditional methods such as maritime satellite phones and VHF (Very High Frequency) radios.

[0003] Existing maritime communication technologies have significant shortcomings: reliance on maritime satellites leads to high operating costs; conventional VHF radios are limited by communication distance and functionality, supporting only voice and unable to effectively transmit data; at the same time, single communication methods are unreliable in harsh sea conditions and lack backup mechanisms; overall, existing systems are unable to meet the urgent needs of modern maritime operations for low cost, high reliability, and integrated data and voice interaction.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a maritime long-range interactive communication system.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a maritime remote interactive communication system. This system effectively solves the problems of high cost, poor reliability, and limited functionality in maritime communication by integrating multiple communication modules and introducing intelligent switching and power management mechanisms.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A maritime long-range interactive communication system includes a shipborne terminal and a shore-based control center. The shipborne terminal includes a main controller and a multi-mode communication module, a data acquisition module, a human-machine interaction module, and a power management module electrically connected to the main controller.

The multi-mode communication module includes a satellite communication module, a 4G / 5G mobile communication module 22, and a medium-frequency / high-frequency radio communication module. The main controller is configured to generate a switching control signal based on the network signal status of the 4G / 5G mobile communication module to drive the medium-frequency / high-frequency radio communication module or the satellite communication module into a working state.

[0008] In one or more embodiments of this utility model, the satellite communication module is a Beidou short message communication module, which is connected to the main controller through a UART interface, and its power enable pin is connected to the GPIO interface of the main controller.

Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0020] Example 1

[0021] like Figure 1 and 2As shown, a maritime remote interactive communication system according to one embodiment of the present invention includes a shipborne terminal 100 and a shore-based control center 200. The shipborne terminal 100 includes a main controller 1, and a multi-mode communication module 2, a data acquisition module 3, a human-machine interaction module 4, and a power management module 5 electrically connected to the main controller 1. The shore-based control center 200 includes a server for data interaction with the shipborne terminal 100. The multi-mode communication module 2 includes a satellite communication module 21, a 4G / 5G mobile communication module 22, and a medium-frequency / high-frequency radio communication module 23. The main controller 1 is configured to generate a switching control signal based on the network signal status of the 4G / 5G mobile communication module 22 to drive the medium-frequency / high-frequency radio communication module 23 or the satellite communication module 21 into a working state.

[0022] The working principle of this maritime remote interactive communication system is based on the main controller 1 of the shipborne terminal 100 as the core decision-making unit. By continuously monitoring the signal status of the 4G / 5G mobile communication module 22, the system automatically implements dynamic management of the multi-mode communication module 2 based on this status: in near-shore areas, low-cost mobile networks are used preferentially for data transmission; when the mobile signal weakens or is interrupted, the main controller 1 generates a switching control signal and automatically activates the intermediate frequency / high frequency radio module 23 as a backup communication link; in the event of an emergency, the system will forcibly activate the highly reliable satellite communication module 21, thereby constructing a three-level communication guarantee mechanism of "primary-backup-emergency" driven by cost, signal strength, and event priority, achieving a balance between communication reliability, functionality, and economy in complex maritime environments.

[0023] Specifically, the shipborne terminal 100 is fixedly installed on the ship, and the shore-based control center 200 is deployed in the land-based management center. The shipborne terminal 100 includes a sealed waterproof shell and a main control circuit board installed inside the shell. The main controller 1, and the multi-mode communication module 2, data acquisition module 3, human-machine interaction module 4 and power management module 5 electrically connected to the main controller 1 are respectively integrated on the main control circuit board.

[0024] Furthermore, the main controller 1 employs an industrial-grade microcontroller, equipped with multiple UART, I2C, and GPIO interfaces for physical connection and signal interaction with the following modules. The multi-mode communication module 2 connects to the corresponding serial interface of the main controller 1 via traces on the circuit board. The data acquisition module 3 connects to the main controller 1 via the I2C bus and UART. The power management module 5 is integrated with the main control circuit board; the main controller 1 communicates with the power management chip via the I2C bus and can control the enable state of each voltage regulator circuit via GPIO pins. The 4G / 5G mobile communication module 22 uses an LTE communication module, and its USB pin connects to the USB interface of the main controller 1. The intermediate frequency / high frequency radio communication module 23 connects its serial port pin to another UART interface of the main controller 1.

[0025] Satellite communication module 21 is a Beidou short message communication module, which is connected to the main controller 1 through the UART interface, and its power enable pin is connected to the GPIO interface of the main controller 1.

[0026] like Figure 2 As shown, the data acquisition module 3 includes a GPS / BeiDou positioning unit 31 and a ship attitude sensor 32, and is connected to the main controller 1 via an I2C bus or a UART interface.

[0027] Specifically, the output terminal of the ship attitude sensor 32 is connected to the signal input terminal of the main controller 1; when the data output by the ship attitude sensor 32 exceeds a preset threshold, the main controller 1 is triggered to generate an emergency control signal to activate the satellite communication module 21.

[0028] like Figure 2 As shown, the power management module 5 includes a power input circuit 51 connected to the ship's power supply, a battery 52, and a multi-output voltage regulator circuit that provides different voltages to each module; the main controller 1 communicates with the power management chip through the I2C bus and controls the enable state of specific circuit channels in the multi-output voltage regulator circuit through the GPIO interface.

[0029] like Figure 2 As shown, the power management module 5 also includes a solar charging unit 53 connected to the battery 52.

[0030] like Figure 2 As shown, the human-computer interaction module 4 includes a touch screen 41 connected to the main controller 1 via an RGB interface and a USB interface, and an audio unit 42 connected to the main controller 1 via an I2S audio interface.

[0031] The aforementioned hardware modules are connected through specific circuits to form a physical system capable of automatically managing communication links.

[0032] The main controller 1 is configured with communication link management functions by hardware circuitry and preset logic. Specifically, after system initialization, the 4G / 5G mobile communication module 22 is configured as the default communication link. The signal detection circuit built into the main controller 1 continuously monitors the network signal strength of the 4G / 5G module 22; when the signal strength is lower than a preset hardware threshold, the main controller 1 generates a switching control signal. For non-emergency data, this switching control signal drives the circuitry of the intermediate frequency / high frequency radio communication module 23 to enter the working state and receives the data to be transmitted through its UART interface. When the emergency event triggering circuit is activated, such as when the SOS button is pressed to generate an interrupt signal, or when the data output by the attitude sensor 32 exceeds the set threshold of the hardware comparator, the main controller 1 immediately generates a highest priority control signal. This signal directly controls the power enable pin of the satellite communication module 21, enabling it to power on and simultaneously sending alarm data to the module through the UART interface.

[0033] Through the connection and coordinated operation of the above hardware modules, this utility model realizes automatic and reliable switching of communication links.

[0034] Example 2

[0035] This embodiment further describes the low-power hardware configuration of the power management module 5 based on embodiment one.

[0036] The main controller 1 is configured to work in conjunction with the power management chip. When data from the positioning module 31 indicates that the ship has been stationary for more than a preset time, the main controller 1 sends a shutdown signal to the backlight driver circuit of the touch screen 41 via the GPIO interface and cuts off the power supply to the power amplifier circuit of the HF module 23. This construction, which uses hardware signals to provide time-sharing power to the power-consuming modules, effectively reduces the overall power consumption of the system.

[0037] Example 3: This embodiment, based on Embodiment 1, adds a physical connection structure for a handheld emergency terminal. The system also includes a handheld emergency terminal, which integrates a first low-power Bluetooth module; a second low-power Bluetooth module paired with the first low-power Bluetooth module is integrated on the main control circuit board of the shipborne terminal 100; the handheld emergency terminal serves as a remote audio input / output interface for the shipborne terminal 100 through an established Bluetooth wireless communication channel. After the two Bluetooth modules establish a wireless physical channel, the handheld emergency terminal physically becomes a remote audio input / output interface for the shipborne terminal 100, expanding the physical usability of the system.
