Description

Technical Field

[0001] The present application belongs to the field of ship monitoring technology, and in particular relates to a ship identification device and a control method thereof, and shipborne equipment. Background Art

[0002] As a key technology for maritime safety and communication, the Automatic Identification System (AIS) broadcasts important information such as vessel position, speed, and heading in real time. This effectively reduces the risk of collisions in low-visibility navigation environments, such as at night and inclement weather, and improves shipping management efficiency and navigation safety. Through information exchange between ship and shore, and between ships, AIS has become an essential component of modern navigation.

[0003] In related technologies, if the AIS equipment is in an environment without external power supply, it is often difficult to meet the demand for long-term uninterrupted position reporting due to the lack of reliable backup power supply, resulting in interruption of ship dynamic information and increased risk of maritime navigation; in some technologies, although a backup power supply is equipped, the power consumption of the backup power supply is high, resulting in a short battery life of the backup power supply, which in turn affects the reliability of the AIS equipment.

DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the terms "length", "width", "up", "down", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0040] It's important to note that the Automatic Identification System (AIS), a core technology for modern maritime safety and communications, plays a key role in ship-to-shore and ship-to-ship information exchange. The system broadcasts key information such as the ship's position, speed, course, name, and call sign in real time. This significantly reduces the risk of collisions, improves shipping management efficiency, and enhances waterway safety, particularly in low-visibility navigation environments such as at night, in fog, or during heavy rain. It has become an essential piece of infrastructure for modern navigation.

[0041] In related technologies, AIS equipment faces two major technical bottlenecks when operating without an external power supply: First, most devices lack reliable backup power solutions, making it difficult to meet the demand for long-term, uninterrupted position reporting when the external power supply is interrupted. This directly causes interruptions in ship dynamic information and significantly increases the risk of maritime navigation. Second, some technical solutions equipped with backup power supplies have power consumption control defects. The backup power supply is in operation even when the equipment is not in use (such as during storage and transportation). Combined with the non-rechargeable nature of the battery, it leads to excessive battery capacity consumption. Once the equipment is officially in use, the backup power supply life cannot meet industry standards (such as at least three years of continuous operation), seriously affecting the reliability of the AIS equipment.

[0042] Based on this, the present application improves the relevant ship identification device and its control method, as well as the shipborne equipment.

[0043] See also Figure 1 , Figure 1 A structural schematic diagram of the ship identification device provided in this embodiment is shown; the ship identification device of the embodiment of the present application includes a standby state and an enabled state, and the ship identification device includes an information interaction module 100, a first power supply module 200 and a second power supply module 300; the information interaction module 100 is used to transmit ship data to the outside; the first power supply module 200 is used to access external power supply in the enabled state to power the information interaction module 100; the second power supply module 300 includes a battery 310 and a switch unit 320, and the battery 310 is used to power the information interaction module 100; the switch unit 320 is arranged between the battery 310 and the information interaction module 100, and is used to control the disconnection between the battery 310 and the information interaction module 100 in the standby state, and is used to control the conduction between the battery 310 and the information interaction module 100 in the enabled state and when the first power supply module 200 stops powering the information interaction module 100.

[0044] It should be explained that the information interaction module 100 is a functional module for obtaining data such as the ship's position and speed, and transmitting ship dynamic information to the outside. The first power supply module 200 is a power supply component that is connected to an external power source when the device is enabled to provide power to the information interaction module 100. The second power supply module 300 includes a non-rechargeable disposable battery and a switch unit 320, which is a module for powering the information interaction module 100 when there is no external power supply. The switch unit 320 is a control component arranged between the battery 310 and the information interaction module 100, which can control the power supply status of the battery 310 by switching the circuit on and off. The waiting state is the state of the equipment in the storage, transportation and other stages before it is officially loaded and activated. At this time, the battery 310 is disconnected from the information interaction module 100. The enabled state is the state in which the equipment is officially put into use after loading. It can be powered by the first power supply module 200 when the external power supply is normal, or it can be switched to the battery 310 for power when the external power supply is interrupted.

[0045] It is understood that the switch unit 320 of the second power supply module 300 controls the disconnection of the battery 310 from the information interaction module 100 when in the standby state, thereby preventing the device from consuming power due to the activation of the battery 310 during the storage and transportation stages, and thus reducing unnecessary loss of the battery 310 during the non-activation stage. When the device enters the activated state and the first power supply module 200 stops supplying power, the switch unit 320 controls the connection between the battery 310 and the information interaction module 100, causing the battery 310 to automatically power the information interaction module 100, ensuring that data such as the ship's position can continue to be transmitted even without external power supply, thus facilitating uninterrupted position reporting and ensuring the safe navigation of the ship.

[0046] In some embodiments of the present application, the switch unit 320 includes a first sub-switch unit and a second sub-switch unit, and the first sub-switch unit and the second sub-switch unit are used to jointly control the disconnection and conduction between the battery 310 and the information interaction module 100; wherein, the first sub-switch unit is used to control the disconnection between the battery 310 and the information interaction module 100 in the standby state, and to control the conduction between the battery 310 and the information interaction module 100 in the enabled state; the second sub-switch unit is used to control the disconnection between the battery 310 and the information interaction module 100 when the first power supply module 200 supplies power to the information interaction module 100, and to control the conduction between the battery 310 and the information interaction module 100 when the first power supply module 200 stops supplying power to the information interaction module 100.

[0047] It should be explained that the first sub-switch unit is a component of the switch unit 320 and is used to disconnect the battery 310 from the information interaction module 100 when the device is in the standby state, and to connect the battery 310 and the information interaction module 100 when the device is in the enabled state. The second sub-switch unit is a component of the switch unit 320 and is used to disconnect the battery 310 from the information interaction module 100 when the first power supply module 200 is normally supplying power, and to connect the battery 310 and the information interaction module 100 when the first power supply module 200 stops supplying power.

[0048] It is understood that during the storage and transportation phases of the equipment, the first sub-switch unit disconnects the battery 310 from the information interaction module 100, preventing the battery 310 from consuming power when not in use, thereby reducing unnecessary loss of the battery 310 when not in use. Once the equipment is loaded onto a vessel and activated, the first sub-switch unit connects the battery 310 to the information interaction module 100. Simultaneously, the second sub-switch unit controls the connection or disconnection of the battery 310 by detecting the power supply status of the first power supply module 200 (e.g., whether the main power supply is lost). When the first power supply module 200 is operating normally, the second sub-switch unit disconnects the battery 310 circuit, preventing redundant power supply from the battery 310. When the first power supply module 200 stops supplying power, the second sub-switch unit connects the battery 310 circuit, allowing the battery 310 to automatically power the information interaction module 100. This ensures that the equipment continues to transmit vessel position data when no external power is supplied, enabling uninterrupted position reporting.

[0049] In some embodiments of this application, please refer to Figure 2 , Figure 2 FIG. 1 shows a circuit diagram of a ship identification device provided in this embodiment; FIG. Figure 2As shown, BAT is the battery 310, Main_POWER is the main power supply (the first power supply module 200); the second sub-switch unit of this embodiment includes a first power switch tube Q1, a second power switch tube Q3, a third power switch tube Q4 and a first resistor; one end of the first power switch tube Q1 is connected to the battery 310, and the other end of the first power switch tube Q1 is connected to the information interaction module 100; one end of the second power switch tube Q3 is connected to the control electrode of the first power switch tube and is used to control the on and off of the first power switch tube Q1, and the other end of the second power switch tube Q3 is grounded; the third One end of the power switch tube Q4 is used to connect to the first power supply, the other end of the third power switch tube Q4 is grounded, and the control electrode of the third power switch tube Q4 is used to connect to the first power supply module 200; one end of the first resistor is connected between the first power supply and the third power switch tube Q4, and the other end of the first resistor is connected to the control electrode of the second power switch tube Q3; the second sub-switch unit is configured so that when the first power supply module 200 loses power, the third power switch tube Q4 and the second power switch tube Q3 are disconnected, and the first power switch tube is turned on, so that the battery 310 and the information interaction module 100 are turned on.

[0050] It should be explained that the first power switch Q1 is a power switching device disposed between the battery 310 and the information interaction module 100. Its conduction state is controlled by the second power switch Q3, directly controlling the on / off state of the circuit between the battery 310 and the information interaction module 100. The second power switch Q3 is a switching device that controls the on / off state of the first power switch Q1. One terminal is connected to the control electrode of the first power switch Q1, and the other terminal is grounded. The operating state of the first power switch Q1 is changed by the on / off state. The third power switch Q4 is a switching device connected to the first power supply module 200 (main power supply). Its control electrode is connected to the first power supply module 200 and is used to detect the power supply status of the main power supply. Its conduction state is controlled by the main power supply voltage. The first resistor is a voltage divider resistor connected in series between the first power supply module 200 and the control electrode of the second power switch Q3. It is used to transmit the main power supply voltage signal to the second power switch Q3 to control its on / off state.

[0051] It can be understood that one end of the first power switch tube Q1 is connected to the battery 310, and the other end is connected to the information interaction module 100, serving as the main path switch for power supply by the battery 310; one end of the second power switch tube Q3 is connected to the control electrode of the first power switch tube Q1, and the other end is grounded, for controlling the conduction or cut-off of the first power switch tube Q1; one end of the third power switch tube Q4 is connected to the first power supply, the other end is grounded, and the control electrode is directly connected to the first power supply module 200, for detecting whether the main power supply is supplying power; one end of the first resistor is connected between the first power supply and the third power switch tube Q4, and the other end is connected to the control electrode of the second power switch tube Q3, for voltage division and transmission of the voltage signal of the main power supply.

[0052] Specifically, when the first power supply module 200 is operating normally, the control electrode of the third power switch Q4 is driven by the main power voltage and turns on, forming a path (grounded) across the third power switch Q4. At this point, after voltage division between the first resistor and the third power switch Q4, the control electrode of the second power switch Q3 receives a low-level signal, turning on the second power switch Q3. After the second power switch Q3 turns on, it pulls the control electrode of the first power switch Q1 low, turning off the first power switch Q1 and disconnecting the battery 310 from the information interaction module 100. This configuration prevents redundant discharge of the battery 310 when operating from the main power source, thereby reducing unnecessary power consumption of the battery 310.

[0053] When the first power supply module 200 loses power, the control electrode of the third power switch Q4 loses the main power supply voltage, turning off the third power switch Q4. At this point, the first resistor cannot be grounded through the third power switch Q4. The control electrode of the second power switch Q3 receives a high-level signal through the first resistor, causing the second power switch Q3 to turn off. After the second power switch Q3 turns off, the control electrode of the first power switch Q1 is no longer pulled low, turning on the first power switch Q1. The circuit between the battery 310 and the information interaction module 100 is connected, and the battery 310 provides power to the information interaction module 100. This configuration ensures automatic switching to the battery 310 when the main power supply is interrupted, facilitating uninterrupted location reporting for the information interaction module 100.

[0054] In some embodiments, a first diode D1 is provided between the first power supply module 200 and the information interaction module 100 , wherein the anode of the first diode D1 is connected to the first power supply module 200 , and the cathode of the first diode D1 is connected to the information interaction module 100 .

[0055] In some embodiments, the shipborne identification device further includes a first capacitor C1, one end of which is connected between the first power supply module 200 and the first diode D1, and the other end of which is grounded. The first capacitor C1 is a filter capacitor.

[0056] In some embodiments, a second diode D2 is provided between the first power switch Q1 and the information interaction module 100 , wherein the anode of the second diode D2 is connected to the first power switch Q1 , and the cathode of the second diode D2 is connected to the information interaction module 100 .

[0057] In some embodiments, the shipborne identification device further includes a second capacitor C2, one end of which is connected between the battery 310 and the first power switch Q1, and the other end of which is grounded. The second capacitor C2 is a filter capacitor.

[0058] In some embodiments of this application, please continue to refer to Figure 2 In this embodiment, the first power supply is reused with the battery 310 .

[0059] In some embodiments of this application, please continue to refer to Figure 2 The first sub-switch unit of this embodiment includes a fuse, one end of the fuse is connected between the first resistor and the third power switch tube Q4, and the other end of the fuse is grounded; the fuse is configured to be turned on in the waiting state and configured to be blown in the enabled state.

[0060] It should be explained that the fuse is an irreversible thermal cutoff device connected in series between the first resistor and the third power switch tube Q4. It remains conductive in the enabled state and is triggered to melt due to current in the enabled state, forming an irreversible physical path.

[0061] It is understood that during storage and transportation, the fuse remains on, and the third power switch Q4 is off because it is disconnected from the first power supply. The first resistor and the fuse form a voltage divider circuit, maintaining a low voltage at the control electrode of the second power switch Q3, thereby keeping the first power switch Q1 off and disconnecting the battery 310 from the information interaction module 100. This configuration, by maintaining the fuse on, ensures that the electrical connection of the battery 310 circuit is controlled before the device is activated, preventing damage to the battery 310 due to unexpected current flow.

[0062] After the equipment is shipped, the first power supply is connected, the third power switch Q4 turns on, and the first resistor and the third power switch Q4 form a circuit, allowing current to flow through the fuse. Due to the preset rated current of the fuse, it triggers a blown action, causing the fuse to permanently open from the on state, while simultaneously creating a new physical circuit (e.g., through the post-fuse device structure). This blown action switches the first sub-switch unit to the on state. Combined with the power switching logic of the second sub-switch unit, this ensures that the battery 310 can connect to the information interaction module 100 in the event of a main power outage.

[0063] In some embodiments of this application, please continue to refer to Figure 2 ,like Figure 2 As shown, MCU_GPIO_PC13 is a control signal. The ship identification device of this embodiment further includes a control module configured to output a control signal when the ship identification device switches from a standby state to an enabled state. The first sub-switch unit further includes a fourth power switch tube Q2, one end of which is connected between the first resistor and the fuse, the other end of which is configured to receive the second power supply, and the control electrode of the fourth power switch tube Q2 is configured to connect to the control module. The fourth power switch tube Q2 is configured to conduct in response to the control signal and connect the second power supply and the fuse, thereby blowing the fuse.

[0064] It's important to explain that the control module is a control unit based on a microcontroller (MCU). It outputs control signals to drive peripheral devices when the ship identification device switches from the standby state to the active state. The fourth power switch Q2 is a power switch device located in the first sub-switch unit. One end is connected between the first resistor and the fuse, the other end is connected to the second power supply, and the control electrode is connected to the control module, enabling the circuit to operate according to the control signal.

[0065] It can be understood that the control module outputs a control signal through the MCU to ensure that the fourth power switch tube Q2 is turned on only when the device is officially enabled, avoiding the fuse from being triggered by unexpected current during the storage and transportation stage, which is conducive to accurately controlling the activation timing of the battery 310 and reducing unnecessary power consumption.

[0066] In some embodiments of the present application, the second power supply is multiplexed with the first power supply module 200 .

[0067] In some embodiments of the present application, the first power switch tube Q1 , the second power switch tube Q3 , the third power switch tube Q4 and the fourth power switch tube Q2 are selected from one of MOS tubes, triodes and TFT tubes.

[0068] In some embodiments, the first power switch tube Q1 is a P-type MOS tube, and the second power switch tube Q3 , the third power switch tube Q4 , and the fourth power switch tube Q2 are N-type MOS tubes.

[0069] In some embodiments of the present application, the information interaction module 100 includes a timing unit and a functional unit. The functional unit has a sleep state and a non-sleep state. When the second power supply module 300 supplies power to the information interaction module 100, the timing unit is used to wake up the functional unit from the sleep state to the non-sleep state at every preset time interval.

[0070] It should be explained that the timing unit is a timer-based wake-up circuit (e.g., a timer based on a real-time clock (RTC)) integrated within the information interaction module 100. It is powered independently of the functional unit and is used to periodically generate a wake-up signal. The functional unit is the core operating circuitry of the information interaction module 100 (including functions such as GNSS positioning and AIS signal processing). In sleep mode, high-power peripherals (e.g., RF receiver and signal amplification circuit) are disabled, maintaining only basic register data. In non-sleep mode, it operates fully functionally, outputting identification information such as the vessel's position and identity. The preset wake-up period is the factory-configured wake-up period (e.g., 24 hours / time), which can be adjusted by writing parameters into the control module to balance positioning frequency with battery life.

[0071] Understandably, the functional units spend most of their time in sleep mode, with only the timing unit operating at minimal power consumption. Combined with the power-off logic of switch unit 320, this significantly reduces the energy consumption of battery 310. This allows battery 310 to continuously support positioning throughout the device's lifecycle (storage, operation, and backup), avoiding unnecessary power consumption and adapting to the long-term needs of ships.

[0072] In some embodiments, the vessel data includes at least one of a vessel name, a vessel model, a vessel position, and a vessel speed.

[0073] In some embodiments of the present application, the information interaction module 100 also includes a positioning unit, a receiving unit and a transmitting unit. The receiving unit is used to receive satellite positioning data, the positioning unit is used to store ship data, and the transmitting unit is used to transmit ship data to the outside; the information interaction module 100 is configured to power the information interaction module 100 with the second power supply module 300, and to turn off the receiving unit when the transmitting unit is working.

[0074] It's important to explain that the receiving unit integrates GNSS RF reception and baseband decoding circuits, responsible for capturing satellite signals and calculating positioning data. It requires a continuous RF link (high power consumption) during operation. The transmitting unit, which includes AIS signal encoding and power amplification circuits, modulates positioning data and vessel identity information into maritime standard signals (such as AISVDM messages) for broadcast, requiring high current drive at the moment of transmission.

[0075] It is understandable that this helps to reduce the consumption of the battery 310 by the receiving unit.

[0076] In some embodiments of this application, please continue to refer to Figure 2 The information interaction module 100 of this embodiment further includes a secondary power supply unit, which is electrically connected to the first power supply module 200 and the second power supply module 300.

[0077] Furthermore, in order to better implement the ship identification device in any of the above embodiments, based on the above ship identification device, the embodiment of the present application also provides a control method for the ship identification device, which is applied to the above ship identification device, please refer to Figure 3 , Figure 3 A schematic diagram showing the steps of a control method for a ship identification device provided in this embodiment is shown; the control method of this embodiment includes:

[0078] S100: When the ship identification device is in a waiting state, the connection between the battery 310 and the information interaction module 100 is turned off; specifically, when the ship identification device is in a waiting state (such as storage or transportation), the connection between the battery 310 and the information interaction module 100 is turned off to avoid unnecessary power consumption of the battery 310 before the device is officially activated.

[0079] S200: The vessel identification device is switched to the enabled state, with the first power supply module 200 supplying power to the information interaction module 100. If the first power supply module 200 loses power, the battery 310 provides power to the information interaction module 100. Specifically, after the device is switched to the enabled state, the first power supply module 200 (the main power source) prioritizes powering the information interaction module 100. If the main power source loses power, power automatically switches to the battery 310, ensuring uninterrupted position reporting.

[0080] Furthermore, in order to better implement the ship identification device in any of the above embodiments, based on the above ship identification device, an embodiment of the present application also provides a shipborne equipment, and the shipborne equipment includes the above ship identification device.
