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.

Detailed Embodiments

[0021] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] It should be noted that when an element is referred to as being "disposed on" another element, it can 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 can be directly connected to the other element or indirectly connected to the other element.

[0023] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0024] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0025] It should be known that the Automatic Identification System (AIS) of ships, as the core technology of modern maritime safety and communication, plays a key role in ship-shore and ship-ship information interaction. This system can broadcast key information such as ship position, speed, course, ship name, call sign, etc. in real time. Especially in navigation environments with poor visibility such as at night, in fog, and in heavy rain, it can significantly reduce the risk of ship collisions, improve the efficiency of shipping management and the safety of waterway passage, and has become an essential basic equipment for modern navigation.

[0026] In the related technology, AIS devices face two major technical bottlenecks in an environment without external power supply: First, most devices lack a reliable backup power solution, resulting in difficulty in meeting the demand for long-term uninterrupted position reporting when external power supply is interrupted, directly causing the interruption of ship dynamic information and greatly increasing the risk of maritime navigation; Second, some technical solutions equipped with backup power have power consumption control defects. The backup power is in a working state during the stage when the device is not enabled (such as in the storage and transportation links). Coupled with the non-rechargeable characteristic of the battery, the battery capacity is excessively consumed. When the device is officially enabled, the endurance time of the backup power cannot meet the industry standard (such as continuous operation for no less than 3 years), seriously affecting the reliability of AIS devices.

[0027] Based on this, the present application has improved the related ship identification device, its control method, and on-board equipment.

[0028] Please refer toFigure 1 , Figure 1 shows a schematic structural diagram of the ship identification device provided in this embodiment; the ship identification device in the embodiment of the present application includes a to-be-enabled 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 connect to an external power supply in the enabled state to supply power to 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 supply power to 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 to-be-enabled 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 supplying power to the information interaction module 100.

[0029] 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 the ship's dynamic information to the outside. The first power supply module 200 is a power supply component that connects to an external power source in the enabled state of the device 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, and is a module for supplying power to 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, and can control the power supply state of the battery 310 through circuit on / off. The to-be-enabled state is the state of the device during the unloaded and not-yet-formally-installed stages such as warehousing and transportation. At this time, the battery 310 is disconnected from the information interaction module 100. The enabled state is the state when the device is formally put into use after being installed on the ship. It can be powered by the first power supply module 200 when the external power supply is normal, or switched to the battery 310 for power supply when the external power supply is interrupted.

[0030] It can be understood that the switch unit 320 of the second power supply module 300 controls the disconnection between the battery 310 and the information interaction module 100 in the to-be-enabled state, avoiding power consumption due to the activation of the battery 310 during the warehousing and transportation stages of the device, which is beneficial to reducing unnecessary losses of the battery 310 during the non-enabled stage. When the device enters the enabled state and the first power supply module 200 stops supplying power, the switch unit 320 controls the conduction between the battery 310 and the information interaction module 100, enabling the battery 310 to automatically supply power to the information interaction module 100, ensuring that ship position and other data can still be continuously transmitted when there is no external power supply, which is beneficial to realizing the uninterrupted position reporting function and ensuring the safety of ship navigation.

[0031] In some embodiments of the present application, the switch unit 320 includes a first sub-switch unit and a second sub-switch unit. 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. Among them, the first sub-switch unit is used to control the disconnection between the battery 310 and the information interaction module 100 in the to-be-enabled state, and is used 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 is used 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.

[0032] It should be explained that the first sub-switch unit is a component of the switch unit 320, which is used to cut off the connection between the battery 310 and the information interaction module 100 in the to-be-enabled state of the device, and conduct the circuit between the battery 310 and the information interaction module 100 in the enabled state. The second sub-switch unit is a component of the switch unit 320, which is used to disconnect the battery 310 and the information interaction module 100 when the first power supply module 200 supplies power normally, and conduct the battery 310 and the information interaction module 100 when the first power supply module 200 stops supplying power.

[0033] It can be understood that during the storage and transportation stages of the device, the first sub-switch unit maintains the disconnection between the battery 310 and the information interaction module 100, avoiding power consumption of the battery 310 in the non-enabled stage, which is beneficial to reducing unnecessary losses of the battery 310 in the non-working state. When the device is shipped and enabled, the first sub-switch unit conducts the battery 310 and the information interaction module 100. At the same time, the second sub-switch unit controls the access or disconnection of the battery 310 by detecting the power supply state of the first power supply module 200 (such as whether the main power supply is powered off). When the first power supply module 200 supplies power normally, the second sub-switch unit cuts off the battery 310 circuit to avoid redundant power supply of the battery 310. When the first power supply module 200 stops supplying power, the second sub-switch unit conducts the battery 310 circuit, enabling the battery 310 to automatically supply power to the information interaction module 100, which is beneficial to ensuring that the device continuously transmits ship position data without external power supply and realizing uninterrupted position reporting.

[0034] In some embodiments of the present application, please refer to Figure 2 , Figure 2 shows a schematic circuit structure diagram of the ship identification device provided in this embodiment; as Figure 2As shown, BAT is the battery 310, and 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 / off of the first power switch tube Q1, and the other end of the second power switch tube Q3 is grounded; one end of the third 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 to, when the first power supply module 200 loses power, turn off the third power switch tube Q4 and the second power switch tube Q3, and turn on the first power switch tube, so as to turn on the battery 310 and the information interaction module 100.

[0035] It should be explained that the first power switch tube Q1 is a power switch device disposed between the battery 310 and the information interaction module 100, and its on state is controlled by the second power switch tube Q3, and is used to directly control the on / off of the circuit between the battery 310 and the information interaction module 100. The second power switch tube Q3 is a switch device that controls the on / off of the first power switch tube Q1, one end is connected to the control electrode of the first power switch tube Q1, and the other end is grounded, and the working state of the first power switch tube Q1 is changed by its on or off state. The third power switch tube Q4 is a switch device connected to the first power supply module 200 (main power supply), and its control electrode is connected to the first power supply module 200, and is used to detect the power supply state of the main power supply, and its on or off state is controlled by the main power supply voltage. The first resistor is a voltage-dividing resistor connected in series between the first power supply module 200 and the control electrode of the second power switch tube Q3, and is used to transmit the main power supply voltage signal to the second power switch tube Q3 to control its on / off state.

[0036] 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 the battery 310 to supply power; 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, and is used to control the on or off of the first power switch tube Q1; one end of the third power switch tube Q4 is connected to the first power supply, and the other end is grounded, and the control electrode is directly connected to the first power supply module 200, and is used to detect 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, and is used to divide and transmit the voltage signal of the main power supply.

[0037] Specifically, when the first power supply module 200 supplies power normally, the control electrode of the third power switch Q4 is driven by the main power supply voltage and conducts, forming a path (grounded) across the third power switch Q4. At this time, after the first resistor and the third power switch Q4 divide the voltage, the control electrode of the second power switch Q3 obtains a low-level signal, causing the second power switch Q3 to conduct. After the second power switch Q3 conducts, it pulls down the control electrode of the first power switch Q1, causing the first power switch Q1 to cut off, and the circuit between the battery 310 and the information interaction module 100 is disconnected. This setting avoids redundant discharge of the battery 310 when the main power supply is on, which is beneficial to reducing unnecessary power consumption of the battery 310.

[0038] When the first power supply module 200 loses power, the control electrode of the third power switch Q4 loses the main power supply voltage, and the third power switch Q4 cuts off. At this time, the first resistor cannot be grounded through the third power switch Q4, and the control electrode of the second power switch Q3 obtains a high-level signal through the first resistor, causing the second power switch Q3 to cut off. After the second power switch Q3 cuts off, the control electrode of the first power switch Q1 is no longer pulled down, and the first power switch Q1 conducts, and the circuit between the battery 310 and the information interaction module 100 is conducted, and the battery 310 supplies power to the information interaction module 100. This setting ensures automatic switching to battery 310 power supply when the main power supply is interrupted, which is beneficial to realizing the uninterrupted position reporting function of the information interaction module 100.

[0039] In some embodiments, a first diode D1 is provided between the first power supply module 200 and the information interaction module 100. The positive electrode of the first diode D1 is connected to the first power supply module 200, and the negative electrode of the first diode D1 is connected to the information interaction module 100.

[0040] In some embodiments, the on-board identification device further includes a first capacitor C1. One end of the first capacitor C1 is connected between the first power supply module 200 and the first diode D1, and the other end of the first capacitor C1 is grounded. The first capacitor C1 is a filtering capacitor.

[0041] In some embodiments, a second diode D2 is provided between the first power switch Q1 and the information interaction module 100. The positive electrode of the second diode D2 is connected to the first power switch Q1, and the negative electrode of the second diode D2 is connected to the information interaction module 100.

[0042] In some embodiments, the on-board identification device further includes a second capacitor C2. One end of the second capacitor C2 is connected between the battery 310 and the first power switch Q1, and the other end of the second capacitor C2 is grounded. The second capacitor C2 is a filtering capacitor.

[0043] In some embodiments of the present application, please continue to refer toFigure 2 In this embodiment, the first power supply is multiplexed with the battery 310.

[0044] In some embodiments of the present application, please continue to refer to Figure 2 In this embodiment, the first sub-switching unit includes a fuse. One end of the fuse is connected between the first resistor and the third power switch Q4, and the other end of the fuse is grounded; the fuse is configured to conduct in the to-be-enabled state and is configured to blow in the enabled state.

[0045] It should be explained that the fuse is a non-recoverable thermal fuse device connected in series between the first resistor and the third power switch Q4. It remains conducting in the to-be-enabled state and blows due to current triggering in the enabled state, forming an irreversible physical path.

[0046] It can be understood that during the warehousing and transportation stages of the device, the fuse is in the conducting state. At this time, the third power switch Q4 is cut off because the first power supply is not connected. The first resistor and the fuse form a voltage-dividing circuit, keeping the control electrode of the second power switch Q3 at a low level, and further maintaining the first power switch Q1 in the cut-off state, disconnecting the circuit between the battery 310 and the information interaction module 100. This setting ensures that the electrical connection of the battery 310 circuit is in a controlled state before the device is enabled through the conducting state of the fuse, avoiding battery 310 loss caused by accidental current.

[0047] After the device is shipped, the first power supply is connected, the third power switch Q4 conducts, the first resistor and the third power switch Q4 form a path, and current flows through the fuse. Since the fuse is preset with a rated current, a fusing action is triggered, and the fuse changes from the conducting state to a permanent open circuit, while forming a new physical path (such as through the structure of the blown device). This fusing action switches the first sub-switching unit to the conducting state, combined with the power supply switching logic of the second sub-switching unit, ensuring that the battery 310 can be connected to the information interaction module 100 when the main power supply loses power.

[0048] In some embodiments of the present application, please continue to refer to Figure 2 , as Figure 2 shown, MCU_GPIO_PC13 is a control signal. The ship identification device of this embodiment further includes a control module, which is used to output a control signal when the ship identification device switches from the to-be-enabled state to the enabled state; the first sub-switching unit further includes a fourth power switch Q2. One end of the fourth power switch Q2 is connected between the first resistor and the fuse, the other end of the fourth power switch Q2 is used to connect to the second power supply, and the control electrode of the fourth power switch Q2 is used to connect to the control module; the fourth power switch Q2 is used to conduct according to the control signal and connect the second power supply and the fuse to blow the fuse.

[0049] It should be explained that the control module is a control unit with a microcontroller (MCU) as the core. When the ship identification device switches from the to-be-enabled state to the enabled state, it outputs a control signal to drive the peripheral devices to act. The fourth power switch tube Q2 is a power switch device arranged in the first sub-switch unit, with one end connected between the first resistor and the fuse, the other end connected to the second power supply, and the control electrode connected to the control module, which is used to conduct the circuit according to the control signal.

[0050] It can be understood that the control module outputs a control signal through the MCU to ensure that the fourth power switch tube Q2 conducts only when the device is officially enabled, avoiding the fuse from melting due to accidental current during the warehousing and transportation stages, which is beneficial to accurately control the enabling timing of the battery 310 and reduce unnecessary power consumption.

[0051] In some embodiments of the present application, the second power supply is multiplexed with the first power supply module 200.

[0052] 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.

[0053] 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.

[0054] In some embodiments of the present application, the information interaction module 10 includes a timing unit and a function unit. The function 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 function unit from the sleep state to the non-sleep state at every preset time interval.

[0055] It should be explained that the timing unit is a timing wake-up circuit integrated in the information interaction module 100 (such as a timer based on an RTC real-time clock), which is powered independently of the function unit and is used to generate wake-up signals periodically. The function unit is the core working circuit of the information interaction module 100 (including functions such as GNSS positioning and AIS signal processing). In the sleep state, high-power-consuming peripherals (such as radio frequency receivers and signal amplification circuits) are turned off, and only basic register data is maintained; in the non-sleep state, it operates with all functions and outputs identification information such as the ship's position and identity. The preset time interval is the wake-up period configured at the factory of the device (such as once every 24 hours), which can be adjusted by writing parameters through the control module to balance the positioning frequency and the battery 310 endurance.

[0056] It can be understood that the functional units are in a sleep state most of the time, and only the timing unit operates with low power consumption. Combining with the power cut-off logic of the switch unit 320, the power consumption of the battery 310 is significantly reduced. This enables the battery 310 to continuously support positioning throughout the entire life cycle of the device (warehousing, operation, backup), avoiding unnecessary power consumption and meeting the long-term usage requirements of ships.

[0057] In some embodiments, the ship data includes at least one of the ship name, ship model, ship position, and ship speed.

[0058] In some embodiments of the present application, the information interaction module 100 further 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 turn off the receiving unit when the second power supply module 300 supplies power to the information interaction module 100 and when the transmitting unit is working.

[0059] It should be explained that the receiving unit integrates a GNSS radio frequency receiver and a baseband decoding circuit, which is responsible for capturing satellite signals and resolving positioning data, and needs to continuously maintain the radio frequency link (high power consumption) during operation. The transmitting unit includes an AIS signal encoding and power amplification circuit, which is used to modulate positioning data and ship identity information into maritime standard signals (such as AIS VDM messages) and broadcast them to the outside. A large current is required to drive the transmitting unit instantaneously.

[0060] It can be understood that this is beneficial to reducing the consumption of the battery 310 by the receiving unit.

[0061] In some embodiments of the present application, please continue to refer to Figure 2 , the information interaction module 100 of this embodiment further includes a secondary power supply unit, and the secondary power supply unit is electrically connected to the first power supply module 200 and the second power supply module 300.

[0062] 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 further provides a control method for the ship identification device, which is applied to the ship identification device as described above. Please refer to Figure 3 , Figure 3 shows a schematic diagram of the steps of the control method for the ship identification device provided in this embodiment; the control method of this embodiment includes: S100: When the ship identification device is in a to-be-enabled state, disconnect the connection between the battery 310 and the information interaction module 100; specifically, when the ship identification device is in a to-be-enabled state (such as during warehousing and transportation), disconnect the connection between the battery 310 and the information interaction module 100, aiming to avoid unnecessary power consumption of the battery 310 before the device is officially enabled.

[0063] S200: Switch the ship identification device to the enabled state, and the first power supply module 200 supplies power to the information interaction module 100; if the first power supply module 200 loses power, the battery 310 supplies power to the information interaction module 100. Specifically, after the device is switched to the enabled state, the first power supply module 200 (main power supply) preferentially supplies power to the information interaction module 100, and automatically switches to the battery 310 for power supply when the main power supply loses power, realizing an uninterrupted position reporting function.

[0064] 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 further provides a shipborne device, and the shipborne device includes the above ship identification device.
