Description

Technical Field

[0001] This invention relates to a method for power failure protection of a Beidou shipborne terminal, specifically to a Beidou shipborne terminal cable connection system, and a method for disconnecting the connection when the Beidou shipborne terminal floats away in the event of a ship sinking accident. Background Technology

[0003] In conjunction with the construction and promotion of my country's BeiDou Navigation Satellite System, a BeiDou shipborne terminal with floating capability has emerged. Ships equipped with floating BeiDou shipborne terminals can automatically report emergencies using the communication and positioning functions of the BeiDou Navigation Satellite System when sinking. In the event of a sinking accident, the BeiDou shipborne terminal can be released from its fixed base via an elastic release device, allowing it to surface and report the emergency. Upon receiving the alarm information, the maritime monitoring platform can promptly arrange and organize search and rescue operations, minimizing losses for the country and its people.

[0004] However, when the BeiDou shipborne terminal is refloating after a shipwreck, although the elastic release device can mechanically release the BeiDou shipborne terminal from the fixed pole base, the connecting cable still connects the BeiDou shipborne terminal to the ship's electrical equipment, preventing the BeiDou shipborne terminal from detaching. The traditional method of disconnecting the connecting cable is generally to use mechanical cutting. When the ship sinks, the mechanical cutting device starts working to cut the connecting cable and release the BeiDou shipborne terminal. This method has problems such as complex design, large space occupation, and high cost. In addition, the mechanical cutting device is prone to corrosion and aging in the long-term salt spray and humid environment of the ocean, and requires regular maintenance. It is inconvenient in both manufacturing and use. Summary of the Invention

[0005] To address the background issues, this invention provides a Beidou shipborne terminal cable connection system and a floating disconnection method. This connection method enables the Beidou shipborne terminal to quickly disconnect from the ship's hull, float to the surface, and report emergencies without damaging the ship's cables.

[0006] The specific technical solution of the present invention is as follows: a Beidou shipborne terminal cable connection system is provided, including a Beidou shipborne terminal, a fixed pole base, a flexible PCB, a connecting cable, in-cabin electrical equipment, and an elastic release device; An elastic release device is connected between the Beidou shipborne terminal and the fixed pole base. At the same time, a flexible PCB is also connected between the Beidou shipborne terminal and the fixed pole base. The electrical equipment inside the cabin is connected to the base of the fixed pole by a connecting cable; The flexible PCB is electrically connected to the connecting cable.

[0007] Furthermore, the fixed rod base is fixed to the ship's mast using clamps.

[0008] Furthermore: the Beidou shipborne terminal has a built-in motherboard, the fixed rod base has a flight socket fixed on it, one end of the flexible PCB is soldered to the built-in motherboard of the Beidou shipborne terminal, and the other end is soldered to the flight socket; one end of the connecting cable is connected to the electrical equipment inside the cabin, and the other end is connected to the flight socket through the flight plug.

[0009] Furthermore, the flexible PCB is pressed and fixed at the end connected to the Beidou shipborne terminal by a pressure block.

[0010] Furthermore, the length of the flexible PCB is less than the height of the elastic release device when it is fully released.

[0011] Furthermore, the flexible PCB has an L-shaped or approximately L-shaped form, and an opening is provided at the inner corner of the L-shaped or approximately L-shaped form.

[0012] The present invention also provides a method for disconnecting a Beidou shipborne terminal from its floating state. A flexible PCB is connected between the Beidou shipborne terminal and a fixed pole base on the ship. At the same time, an elastic release device is connected between the Beidou shipborne terminal and the fixed pole base. The elastic release device is controlled by the shipborne control system. A connecting cable is connected between the fixed pole base and the electrical equipment inside the cabin. The flexible PCB and the connecting cable are electrically connected. When the ship sinks, the elastic release device is released, the flexible PCB is torn apart, and the Beidou shipborne terminal separates from the fixed rod base and floats on the water.

[0013] In the above method, preferably, a flight socket is fixed inside the fixed rod base, one end of the flexible PCB is connected to the flight socket, and the other end is connected to the built-in motherboard of the Beidou shipborne terminal; one end of the connecting cable is connected to the electrical equipment inside the cabin, and the other end is connected to the flight plug, and the flight plug is plugged into the flight socket.

[0014] Preferably, the length of the flexible PCB is less than the height of the elastic release device when it is fully released.

[0015] The advantage of this invention lies in providing a novel method for disconnecting the floating BeiDou shipborne terminal from the fixed pole base. This method eliminates complex mechanical cutting devices and cable connection methods, effectively reducing costs while further improving the speed and reliability of the BeiDou shipborne terminal's buoyancy after sinking. The simple and practical fixed pole base allows for the disconnection of the flexible PCB used for daily power supply and communication between the two when releasing the floating BeiDou shipborne terminal, preventing it from sinking with the ship due to the inability to disconnect the connecting cables after detaching from the fixed pole base.

[0016] The invention has demonstrated excellent performance in both simulation tests and practical applications, effectively reducing costs and decreasing the failure rate of BeiDou shipborne terminals during buoyancy, resulting in significant economic benefits. Vessels using this invention can be widely applied in fields such as fishing and coast guard patrol and law enforcement. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Those skilled in the art should know that the following embodiments are not the only limitation on the technical solution of the present invention. Any equivalent transformations or modifications made under the spirit and essence of the technical solution of the present invention should be considered as falling within the protection scope of the present invention.

[0019] like Figure 1 As shown, the traditional Beidou shipborne terminal cable connection structure includes: Beidou shipborne terminal 1, fixed pole base 2, mast 3, connecting cable 4, cabin electrical equipment 5, and elastic release device 9. Figure 2 (As shown in the display), the cabin electrical equipment 5 includes controllers, displays and power supplies.

[0020] This invention upgrades and transforms the traditional BeiDou shipborne terminal cable connection structure, providing a novel floating BeiDou shipborne terminal cable connection system, such as... Figure 2 As shown, the new cable connection system includes: Beidou shipborne terminal 1, fixed pole base 2, mast 3, connecting cable 4, cabin electrical equipment 5, flexible PCB 6, aviation socket 7, aviation plug 8, and elastic release device 9.

[0021] During system setup, the Beidou shipborne terminal 1 is mounted on a fixed mast base 2, and then the fixed mast base 2 is bound to the mast 3 using clamps. An elastic release device 9 connects the Beidou shipborne terminal 1 and the fixed mast base 2. The elastic release device 9 is controlled by the shipborne control system. In the event of a shipwreck, the system issues an alarm, and the elastic release device 9 automatically releases the Beidou shipborne terminal 1 upon receiving the alarm command. This is existing technology and will not be elaborated upon here. The Beidou shipborne terminal 1 is mounted outside the hull using the mast 3. The internal electrical equipment 5, including the controller, display screen, and power system, is installed inside the hull. The Beidou shipborne terminal 1 is connected to the internal electrical equipment via a multi-core connecting cable 4, which passes through the mast 3 and the fixed mast base 2. During daily use, the display screen and power supply interact with the Beidou shipborne terminal 1 via the connecting cable 4 and provide power to the Beidou shipborne terminal 1. The Beidou shipborne terminal 1 sends messages at a certain frequency. In the event of a shipwreck, the connecting cable 4 must also be disconnected to allow the Beidou shipborne terminal 1 to completely detach from the hull and float away. The Beidou shipborne terminal 1 is equipped with a battery, which allows it to continue operating even after detaching from the fixed rod base 2 and disconnecting the connecting cable 4. Once the Beidou shipborne terminal 1 surfaces, it can report the emergency. The above is the basic principle of the Beidou shipborne terminal 1's floating operation.

[0022] The traditional cable connection method involves installing a navigation socket inside the housing of the Beidou shipborne terminal 1, with the connecting cable 4 passing through the mast 3 and the base 2 of the fixed pole to connect to the navigation socket. However, when the Beidou shipborne terminal 1 is released, the connecting cable 4 is not disconnected. The traditional method involves mechanically cutting the cable (as described in the background).

[0023] To address this, the present invention modifies the cable connection method, replacing a portion of the connecting cable 4 with a flexible PCB and changing the connection nodes. The core of this method is the use of a flexible PCB 6, on which detection circuitry is installed, replacing a traditional connecting cable 4 between the fixed pole base 2 and the Beidou shipborne terminal 1. The electrical connection between the fixed pole base 2 and the Beidou shipborne terminal 1 is now made using the flexible PCB 6, while the electrical connection between the cabin electrical equipment 5 and the fixed pole base 2 still uses the traditional connecting cable 4. Simultaneously, the installation position of the navigation socket 7 is changed, moving it from inside the housing of the Beidou shipborne terminal 1 to inside the housing of the fixed pole base 2. One end of the connecting cable 4 connects to the electrical equipment 5, and the other end connects to the navigation socket 7 inside the fixed pole base 2. One end of the flexible PCB 6 connects to the navigation socket 7 inside the fixed pole base 2, and the other end connects to the Beidou shipborne terminal 1. Therefore, when the mechanical connection (elastic release device) between the Beidou shipborne terminal 1 and the fixed rod base 2 is disconnected, the elastic release device pulls the flexible PCB 6 to break at the same time, while the connecting cable 4 between the fixed rod base 2 and the electrical equipment 5 in the cabin remains unchanged.

[0024] In a preferred embodiment, the flexible PCB 6 is arranged as follows: Figure 3 As shown, soldering points for flexible PCB 6 are reserved on the built-in motherboard of Beidou shipborne terminal 1. One end of flexible PCB 6 is soldered to the motherboard inside Beidou shipborne terminal. A navigation socket 7 is fixed on the housing of fixed rod base 2. The other end of flexible PCB 6 is soldered to navigation socket 7. A signal line is arranged between the two soldering ends on flexible PCB 6. The arrangement of connecting cable 4 is as follows: keep the connecting cable 4 between the cabin electrical equipment 5 and navigation socket 7 unchanged, connect the end of connecting cable 4 to navigation plug 8, and plug navigation plug 8 into navigation socket 7.

[0025] Through the above implementation method, power and communication signals reach the navigation socket 7 via the connecting cable 4, and then are connected to the motherboard inside the Beidou shipborne terminal 1 via the flexible PCB 6 to achieve circuit connection. The flexible PCB 6 effectively replaces the original connecting cable segment between the fixed rod base 2 and the Beidou shipborne terminal 1, reducing the length of the connecting cable, and the flexible PCB 6 is easy to break. When the Beidou shipborne terminal 1 floats away from the sunken ship, the elastic release device 9 on the fixed rod base 2 releases the Beidou shipborne terminal 1, and the tension generated by the release of the elastic release device 9 pulls the flexible PCB 6 to break, thereby achieving complete float-away of the Beidou shipborne terminal 1. When the Beidou shipborne terminal 1 separates from the fixed rod base 2, no additional auxiliary cutting device is needed. The flexible PCB 6, in conjunction with the elastic release device, can completely disconnect the connection between the fixed rod base 2 and the Beidou shipborne terminal 1 when the ship sinks. This flexible PCB not only effectively replaces the original connecting cable between the fixed rod base and the Beidou shipborne terminal, but also eliminates complex mechanical cutting devices and methods, reducing costs and facilitating production and use.

[0026] In implementing this invention, the installation and fixation of the flexible PCB is a particularly crucial step. A good installation method can not only replace the original connecting cables to complete the transmission of power and communication signals, but also ensure that the flexible PCB can be quickly disconnected in the event of a shipwreck. Figure 3 As shown, further, at the aviation socket end, multiple soldering points are prefabricated at the end of the flexible PCB 6 according to the pin form of the aviation socket 7, and multi-point soldering encapsulation is performed to ensure reliable and stable transmission of power and signals, while preventing the flexible PCB from loosening; at the motherboard end, the flexible PCB is designed in the form of gold fingers and directly soldered to the main board of the Beidou shipborne terminal 1.

[0027] Furthermore, to prevent the flexible PCB 6 from loosening from the Beidou shipborne terminal 1 during buoyancy, the flexible PCB 6 needs to be pressed and fixed at the point where it connects to the Beidou shipborne terminal 1. Otherwise, the flexible PCB cannot be disconnected when the ship sinks, and there is a risk of water entering the Beidou shipborne terminal. Figure 4 As shown, the flexible PCB 6 can be pressed and fixed inside the housing of the Beidou shipborne terminal 1 by the pressure block 10. The pressure block 10 presses the flexible PCB 6 into the groove inside the housing of the Beidou shipborne terminal and then passes through the groove. If necessary, strong glue is dripped at the connection between the pressure block 10 and the groove to assist in fixing. At the same time, the position is sealed.

[0028] Furthermore, to ensure that the flexible PCB 6 can be completely disconnected when the ship sinks, the reserved length of the flexible PCB between the navigation socket 7 and the connection point of the Beidou shipborne terminal 1 must be controlled during installation. It is required that the length of the flexible PCB between the Beidou shipborne terminal 1 and the fixed rod base 2 after installation is less than the height of the elastic release device 9 when it is fully released. That is, when the ship sinks and floats away, the tension generated by the release of the elastic release device 9 can pull the flexible PCB apart, thereby achieving the complete float-away of the Beidou shipborne terminal.

[0029] In addition, the shape design of the flexible PCB 6 is also a crucial step. A reasonable PCB design helps the Beidou shipborne terminal 1 to detach more completely from the fixed rod base 2 during a shipwreck. The flexible PCB 6 is preferably designed in an L-shape or approximately L-shape, such as... Figure 5 As shown, it is even better to open a notch C at the inner corner of the flexible PCB. When the sunken ship floats away, the pulling force generated by the elastic release device 9 acts on one side of the flexible PCB. Taking advantage of the uneven force on the two sides of the flexible PCB, it is easier to tear the flexible PCB from the inner corner. If a notch C is opened at the inner corner, the pulling force when the elastic release device 9 is released will more easily tear the flexible PCB from the notch.

[0030] One end of the flexible PCB 6 is soldered to the motherboard inside the Beidou shipborne terminal 1, and the other end is soldered to the navigation socket 7 on the fixed rod base 2. The flexible PCB 6 ensures the power supply / communication status between the Beidou shipborne terminal 1 and the navigation socket 7. One end of the connecting cable 4 is connected to the internal electrical equipment 5, and the other end is connected to the navigation plug 8. The navigation plug 8 is plugged into the navigation socket 7. The connecting cable 4 ensures the power supply / communication status between the internal electrical equipment 5 and the navigation socket 7. When the Beidou shipborne terminal 1 floats away from the ship, the elastic release device 9 is released, ejecting the Beidou shipborne terminal 1 from the fixed rod base 2. The flexible PCB 6 is then pulled off. The Beidou shipborne terminal 1, with its own power supply and antenna device, floats to the surface after detaching from the ship to report the emergency. Meanwhile, the connecting cable 4 remains connected to the internal electrical equipment 5 and the navigation socket 7, and is undamaged. The navigation socket 7 and the navigation plug 8 are also undamaged as they are fixed inside the fixed rod base 2.

[0031] The present invention also provides a method for disconnecting a Beidou shipborne terminal from floating, wherein a flexible PCB 6 is connected between the Beidou shipborne terminal 1 and the fixed rod base 2 on the ship, and an elastic release device 9 is connected between the Beidou shipborne terminal 1 and the fixed rod base 2. The elastic release device 9 is controlled by the shipborne control system. A connecting cable 4 is connected between the fixed rod base 2 and the electrical equipment 5 in the cabin. The flexible PCB 6 and the connecting cable 4 are electrically connected. When a ship sinks, the elastic release device 9 receives an alarm command from the shipboard control system and releases automatically. At the same time, the flexible PCB 6 is disconnected from the connecting cable 4 due to the release of the elastic release device 9, so the Beidou shipboard terminal 1 is completely separated from the fixed rod base 2.

[0032] Therefore, in the method of the present invention, while releasing the Beidou shipborne terminal 1 from the fixed rod base 2 by the elastic release device 9, the flexible PCB 6 and the connecting cable 4 are also disconnected, so that the Beidou shipborne terminal 1 can completely detach from the hull, float to the surface of the water and report the emergency.

[0033] In the above method, the navigation socket 7 is further fixed in the fixed rod base 2, one end of the flexible PCB 6 is connected to the navigation socket 7, and the other end is connected to the built-in motherboard of the Beidou shipborne terminal 1; one end of the connecting cable 4 is connected to the cabin electrical equipment 5, and the other end is connected to the navigation plug 8, which is plugged into the navigation socket 7.

[0034] The above descriptions are merely specific embodiments of this application, enabling those skilled in the art to understand and implement this application. However, various equivalent modifications and variations to these embodiments will be readily apparent to those skilled in the art. This application is not limited to these embodiments without departing from the spirit or scope of this application, but is to be accorded the scope consistent with the claims of this application.
