Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and in particular to a fishing boat positioning device. Background Art

[0002] A positioning device uses satellite positioning and uploads the acquired positioning data to a server via a mobile communication module (GSM / GPRS network). Typically installed on vehicles, ships, and other vessels, positioning devices typically consist of a positioning module and a communication module. The positioning module is used to obtain the positioning device's location information, which is then transmitted to a cloud server by the communication module. Users interact with the cloud server using their mobile devices (such as mobile phones) to obtain the positioning device's location information, thereby obtaining the location information of vehicles and ships, ensuring their safety.

[0003] Fishing vessels are often equipped with positioning devices to monitor their safety. In extreme cases, fishing vessels (especially small ones) may capsize and fall overboard during navigation. However, currently available positioning devices generally lack a man-overboard alarm function. This means that if a capsize occurs, the positioning device may not issue a timely alarm, compromising the safety of the vessel. Summary of the Invention

[0004] The purpose of the present invention is to provide a fishing boat positioning device, which has a water-fall alarm function, thereby improving the safety of the fishing boat.

[0005] The present invention provides a fishing boat positioning device, comprising a housing, a circuit module, and a water drop detection assembly. The circuit module is disposed within the housing and includes a communication module, a positioning module, and a control module. The water drop detection assembly, the communication module, and the positioning module are all electrically connected to the control module. A mounting hole is provided on a wall of the housing, the mounting hole being in communication with both an inner cavity of the housing and the exterior of the housing. The water drop detection assembly is at least partially disposed within the mounting hole and blocks the mounting hole.

[0006] When the fishing boat positioning device falls into the water, water outside the shell can enter the installation hole to make the water-fall detection component conductive, and the control module sends a water-fall alarm message to the cloud platform through the communication module.

[0007] In one achievable manner, the water drop detection assembly includes a first conductive member and a second conductive member, both of which are electrically connected to the control module; the mounting hole includes a first sub-hole and a second sub-hole spaced apart, the first conductive member is disposed in the first sub-hole and blocks the first sub-hole, and the second conductive member is disposed in the second sub-hole and blocks the second sub-hole;

[0008] When the fishing boat positioning device falls into water, water outside the housing can enter the first sub-hole and the second sub-hole respectively, so that the first conductive member and the second conductive member are conductive.

[0009] In one achievable manner, the first sub-hole and the second sub-hole are arranged close to each other, and a partition is formed on the shell wall of the shell between the first sub-hole and the second sub-hole;

[0010] A groove is provided on the side of the partition close to the outside of the shell, and the first sub-hole and the second sub-hole are connected through the groove; the outer end of the first conductive part and the outer end of the second conductive part are both located on the side of the bottom of the groove close to the inner cavity of the shell.

[0011] In one implementable manner, the first sub-hole and the second sub-hole are both cylindrical holes, the first conductive member and the second conductive member are both cylindrical electrode columns, and the first conductive member and the second conductive member have the same outer diameter; the shortest distance L between the first sub-hole and the second sub-hole satisfies the following conditions:

[0012] L=k*D; wherein D is the outer diameter of the first conductive member, k is the conductive safety factor, and the value range of k is 0.2~0.8.

[0013] In one feasible manner, a first slot is provided on a side of the first conductive member close to the outside of the shell, and the first slot does not penetrate the first conductive member; a second slot is provided on a side of the second conductive member close to the outside of the shell, and the second slot does not penetrate the second conductive member.

[0014] In one achievable manner, the circuit module further includes a circuit board, and the communication module, the positioning module, and the control module are all disposed on the circuit board and are all electrically connected to the circuit board;

[0015] A spring pin is provided on the circuit board, and the spring pin is electrically connected to the circuit board; the spring pin is provided corresponding to the water drop detection component, and the spring pin is in contact with the water drop detection component and is electrically connected.

[0016] In one achievable manner, the mounting hole passes through the shell wall of the shell, and opposite ends of the mounting hole are directly connected to the inner cavity of the shell and the outside of the shell respectively.

[0017] In one feasible manner, the mounting hole passes through the inner surface of the shell, and the mounting hole does not pass through the outer surface of the shell; a through hole is also provided on the shell wall of the shell, one end of the through hole is connected to the side of the mounting hole close to the outside of the shell, and the other end of the through hole is connected to the outside of the shell.

[0018] In one achievable manner, the aperture of the through hole is smaller than the aperture of the mounting hole;

[0019] And / or, the conducting hole is an inclined hole; or, the conducting hole is an L-shaped hole, and the conducting hole includes a first inner hole extending vertically and a second inner hole extending laterally, one end of the first inner hole is connected to the outside of the shell, the other end of the first inner hole is connected to one end of the second inner hole, and the other end of the second inner hole is connected to the side of the mounting hole close to the outside of the shell.

[0020] In one feasible manner, a floating strip is provided on the outer peripheral wall of the shell, and the density of the floating strip is less than the density of the shell; when the fishing boat positioning device falls into the water, the fishing boat positioning device can float on the water surface through the floating strip.

When the fishing boat positioning device falls into water, water outside the shell can enter the installation hole to make the fall-in-water detection component conductive, and then the control module sends a fall-in-water alarm information to the cloud platform through the communication module. The cloud platform then sends the fall-in-water alarm information to the administrator's mobile terminal, so that the administrator can be informed in time of the fishing boat capsizing and falling-in-water accident, thereby realizing the fall-in-water alarm function of the fishing boat positioning device and improving the safety of the fishing boat.

[0038] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0039] The terms "first," "second," "third," and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a particular sequential order.

[0040] The terms "up," "down," "left," "right," "front," "back," "top," and "bottom" (if any) used in the specification and claims of this invention are defined by the positions of structures in the accompanying drawings and the positions of structures relative to each other. These terms are intended solely for clarity and convenience in presenting the technical solution. It should be understood that the use of these terms does not limit the scope of protection claimed in this invention.

[0041] like Figures 1 to 10 As shown, an embodiment of the present invention provides a fishing vessel positioning device for installation on a fixed component (not shown) of a fishing vessel. The fixed component may be a structural component such as a deck or mast of the fishing vessel. The fishing vessel positioning device includes a housing 1, a circuit module 2, and a water drop detection assembly 3. The housing 1 is a sealed structure, and the circuit module 2 is disposed within the housing 1. The circuit module 2 includes a circuit board 21, a communication module 22, a positioning module 23, and a control module 24. The communication module 22, the positioning module 23, and the control module 24 are all disposed on and electrically connected to the circuit board 21. The water drop detection assembly 3 is electrically connected to the circuit board 21. The water drop detection assembly 3, the communication module 22, and the positioning module 23 are all electrically signal-connected to the control module 24 (specifically, the water drop detection assembly 3, the communication module 22, and the positioning module 23 are all electrically signal-connected to the control module 24 via the circuit board 21). Among them, the communication module 22 is used for wireless communication, the positioning module 23 is used to receive positioning information, and the control module 24 is used to wirelessly transmit the positioning information received by the positioning module 23 to the cloud platform 91 (i.e., cloud server) through the communication module 22. The mobile terminal 92 (such as a mobile phone, computer, etc.) of the fishing vessel manager can interact with the cloud platform 91 for data, thereby obtaining positioning information (the specific functions and working principles of the communication module 22 and the positioning module 23 can be referred to the existing technology and will not be repeated here).

[0042] The housing 1 has a mounting hole 11 formed in its wall. This hole 11 communicates with both the interior of the housing 1 and the exterior of the housing 1. The water drop detection assembly 3 is at least partially disposed within the mounting hole 11, blocking the hole 11 and thereby preventing external water, dust, and the like from entering the housing 1 through the mounting hole 11. The connection between the mounting hole 11 and the interior of the housing 1 facilitates electrical connection between the water drop detection assembly 3 and the circuit board 21. Furthermore, the connection between the mounting hole 11 and the exterior of the housing 1 prevents external water from entering the mounting hole 11.

[0043] When the fishing boat positioning device falls into the water, water outside the housing 1 can enter the mounting hole 11, causing the water detection component 3 to conduct. The control module 24 sends a water-falling alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the water-falling alarm message to the administrator's mobile terminal 92 (for example, the control module 24 can send information such as "fishing boat suspected of falling into the water" to the mobile terminal 92 through the communication module 22 and the cloud platform 91 to remind the administrator). Specifically, when the fishing boat positioning device has not fallen into the water, the water-falling detection component 3 is in a disconnected state because it is not in contact with water. At this time, the control module 24 does not send a water-falling alarm message to the cloud platform 91 through the communication module 22; when the fishing boat positioning device falls into the water, water from the outside will enter the mounting hole 11. The water-falling detection component 3 is conducted after contacting the water and generates an electrical signal. The water-falling detection component 3 transmits the electrical signal to the control module 24. After receiving the electrical signal, the control module 24 sends a water-falling alarm message to the cloud platform 91 through the communication module 22.

[0044] The fishing boat positioning device provided in this embodiment is provided with a fall-in-water detection component 3. When the fishing boat positioning device falls into water, water outside the shell 1 can enter the installation hole 11 to make the fall-in-water detection component 3 conductive, and then the control module 24 sends a fall-in-water alarm information to the cloud platform 91 through the communication module 22. The cloud platform 91 then sends the fall-in-water alarm information to the administrator's mobile terminal 92, so that the administrator can know in time that the fishing boat has capsized and fallen into the water, thereby realizing the fall-in-water alarm function of the fishing boat positioning device and improving the safety of the fishing boat.

[0045] like Figure 2 、 Figure 5 and Figure 6As shown, as one embodiment, the outer end of the water drop detection assembly 3 (i.e., the end of the water drop detection assembly 3 closest to the exterior of the housing 1) is spaced apart from the exterior surface of the housing 1. In other words, the water drop detection assembly 3 is completely located within the mounting hole 11. This arrangement reduces the risk of false positives caused by the water drop detection assembly 3 coming into contact with water on the surface of the housing 1 during non-water drop conditions (e.g., rainy weather). (If the outer end of the water drop detection assembly 3 were exposed outside the mounting hole 11 or flush with the exterior surface of the housing 1, water would directly contact the water drop detection assembly 3 when the housing 1 is wet. However, because the outer end of the water drop detection assembly 3 is spaced apart from the exterior surface of the housing 1, i.e., there is a height difference between the outer end of the water drop detection assembly 3 and the exterior surface of the housing 1, water on the surface of the housing 1 will not directly contact the water drop detection assembly 3 when a small amount of water is present, thereby reducing the risk of false positives.) As an embodiment, the height difference between the outer end of the water drop detection component 3 and the outer surface of the housing 1 is 1 mm to 10 mm, or 2 mm to 8 mm, or 4 mm to 6 mm.

[0046] like Figures 2 to 6 and Figure 10 As shown, as one embodiment, the water drop detection assembly 3 includes a first conductive member 31 and a second conductive member 32, both of which are electrically connected to the control module 24. The mounting hole 11 includes a first sub-hole 111 and a second sub-hole 112 spaced apart. The first conductive member 31 is disposed within and blocks the first sub-hole 111, and the second conductive member 32 is disposed within and blocks the second sub-hole 112. When the fishing boat positioning device falls into the water, water outside the housing 1 can enter the first sub-hole 111 and the second sub-hole 112, respectively, allowing water conduction between the first conductive member 31 and the second conductive member 32.

[0047] Specifically, in this embodiment, the water-fall detection component 3 also includes a current detection circuit 33 provided on the circuit board 21. The current detection circuit 33 is electrically connected to the circuit board 21, and the current detection circuit 33 is electrically connected to the first conductive member 31, the second conductive member 32 and the control module 24 respectively (that is, the first conductive member 31 and the second conductive member 32 are electrically connected to the control module 24 through the current detection circuit 33); when the first conductive member 31 and the second conductive member 32 are connected by water, a current loop is formed between the first conductive member 31, the second conductive member 32 and the current detection circuit 33. At this time, the current detection circuit 33 sends an electrical signal to the control module 24. After receiving the electrical signal, the control module 24 sends a water-fall alarm information to the cloud platform 91 through the communication module 22. The current detection circuit 33 may specifically include a resistor. A first conductive element 31, a resistor, and a second conductive element 32 are arranged in series. The control module 24 is connected to both ends of the resistor. When the first conductive element 31 and the second conductive element 32 are conductive, a voltage signal is generated across the resistor (when the first conductive element 31 and the second conductive element 32 are disconnected, no voltage is generated across the resistor). Upon receiving this voltage signal, the control module 24 transmits a water fall alarm to the cloud platform 91 via the communication module 22. Of course, in other embodiments, the current detection circuit 33 may also have other structural forms (for example, including a current sensing switch, an electromagnetic switch, a MOSFET switch circuit, etc.). In other embodiments, the water fall detection assembly 3 may also employ other structures.

[0048] like Figures 2 to 6As shown, as an embodiment, the first sub-hole 111 and the second sub-hole 112 are arranged close to each other, and a partition 12 is formed on the shell wall of the shell 1 between the first sub-hole 111 and the second sub-hole 112. A groove 121 is arranged on the partition 12 close to the outside of the shell 1, the groove 121 is located between the first sub-hole 111 and the second sub-hole 112, and the first sub-hole 111 and the second sub-hole 112 are communicated through the groove 121; the outer end of the first conductive part 31 (i.e. the end of the first conductive part 31 close to the outside of the shell 1) and the outer end of the second conductive part 32 (i.e. the end of the second conductive part 32 close to the outside of the shell 1) are located on the groove bottom 1210 of the groove 121 close to the inner cavity of the shell 1, that is, the lower end of the first conductive part 31 and the lower end of the second conductive part 32 are both located above the groove 121. Among them, by arranging the outer end of the first conductive part 31 and the outer end of the second conductive part 32 to be spaced apart from the outer surface of the shell 1 (i.e. the first conductive part 31 is completely located in the first sub-hole 111, and the second conductive part 32 is completely located in the second sub-hole 112), when there is a small amount of water on the surface of the shell 1, the water on the surface of the shell 1 will not directly contact the first conductive part 31 and the second conductive part 32 to make them conductive, thereby reducing the risk of misjudgment. By arranging the first sub-hole 111 and the second sub-hole 112 close to each other, the distance between the first conductive part 31 and the second conductive part 32 is shortened, and the creepage distance between them is reduced. At the same time, by arranging the groove 121, the creepage distance between the first conductive part 31 and the second conductive part 32 can be further reduced, and the creepage distance between the first conductive part 31 and the second conductive part 32 can be controlled by adjusting the depth of the groove 121; in this way, not only can the first conductive part 31 and the second conductive part 32 be more easily conductive after the fishing boat positioning device falls into the water, thereby improving the sensitivity of the water-falling detection (i.e. even in river water with low conductivity, the first conductive part 31 and the second conductive part 32 can still be conductive. Through experiments, if the creepage distance between the first conductive part 31 and the second conductive part 32 is too large, the first conductive part 31 and the second conductive part 32 can be conductive in seawater with high conductivity, but cannot be conductive or are not sensitive in river water with low conductivity), but also can reduce the risk of misjudgment of the first conductive part 31 and the second conductive part 32 caused by too close creepage distance in rainy weather. As an embodiment, the depth of the groove 121 can be 1mm~4mm, or 2mm~3mm.

[0049] As Figures 2 to 6As shown, as an embodiment, the first sub-hole 111 and the second sub-hole 112 are both cylindrical holes, the first conductive member 31 and the second conductive member 32 are both cylindrical electrode columns, and the outer diameters of the first conductive member 31 and the second conductive member 32 are the same. The outer diameter of the first conductive member 31 is adapted to the diameter of the first sub-hole 111, and the first conductive member 31 and the inner wall of the first sub-hole 111 can be fixed by snapping, interference fitting, etc., and a sealant can be provided between the outer wall of the first conductive member 31 and the inner wall of the first sub-hole 111; the outer diameter of the second conductive member 32 is adapted to the diameter of the second sub-hole 112, and the second conductive member 32 and the inner wall of the second sub-hole 112 can be fixed by snapping, interference fitting, etc., and a sealant can be provided between the outer wall of the second conductive member 32 and the inner wall of the second sub-hole 112.

[0050] The shortest distance L between the first sub-hole 111 and the second sub-hole 112 satisfies the following conditions:

[0051] L = k * D; where D is the outer diameter of the first conductive member 31 (second conductive member 32), and k is the conductive safety factor, with a value of k ranging from 0.2 to 0.8. Since the creepage distance between the first conductive member 31 and the second conductive member 32 is primarily controlled by the distance between the first sub-hole 111 and the second sub-hole 112, this configuration effectively controls the creepage distance between the first conductive member 31 and the second conductive member 32 by controlling the distance between the first sub-hole 111 and the second sub-hole 112 (preventing the creepage distance from being too small or too large). When the outer diameters of the first and second conductive members 31 and 32 are larger, their current-carrying areas are also larger (i.e., the contact area between water and the first and second conductive members 31 and 32 is larger), which means that the first and second conductive members 31 and 32 are more easily conductive. In this case, the distance between the first sub-hole 111 and the second sub-hole 112 can be set relatively large. Conversely, when the outer diameters of the first and second conductive members 31 and 32 are smaller, their current-carrying areas are also smaller. In this case, the distance between the first and second sub-holes 111 and 112 can be set relatively small. For example, if the outer diameter of the first conductive member 31 is 5 mm, then L is 1 mm to 4 mm.

[0052] like Figures 2 to 6As shown, as an embodiment, a first slot 311 is provided on the side of the first conductive member 31 close to the outside of the shell 1 (that is, the lower end of the first conductive member 31 is provided with a first slot 311 recessed inwardly), the first slot 311 is arranged at the center of the first conductive member 31, and the first slot 311 does not pass through the first conductive member 31; a second slot 321 is provided on the side of the second conductive member 32 close to the outside of the shell 1 (that is, the lower end of the second conductive member 32 is provided with a second slot 321 recessed inwardly), the second slot 321 is arranged at the center of the second conductive member 32, and the second slot 321 does not pass through the second conductive member 32. By providing the first slot 311 and the second slot 321, when the fishing boat positioning device falls into the water, external water can enter the first slot 311 and the second slot 321. The first slot 311 and the second slot 321 can increase the current-carrying area of ​​the first conductive component 31 and the second conductive component 32 (that is, the contact area between water and the first conductive component 31 and the second conductive component 32), thereby improving the conduction performance of the first conductive component 31 and the second conductive component 32, and further improving the sensitivity.

[0053] like Figures 2 to 6 As shown, as an embodiment, the mounting hole 11 passes through the shell wall of the housing 1, and the opposite ends of the mounting hole 11 are directly connected to the inner cavity of the housing 1 and the outside of the housing 1, respectively. That is, the first sub-hole 111 and the second sub-hole 112 both pass through the shell wall of the housing 1, and the opposite ends of the first sub-hole 111 and the opposite ends of the second sub-hole 112 are directly connected to the inner cavity of the housing 1 and the outside of the housing 1, respectively.

[0054] like Figure 12 and Figure 13As shown, as another embodiment, the mounting hole 11 is a vertical hole extending vertically. The mounting hole 11 passes through the inner surface of the housing 1, but does not pass through the outer surface of the housing 1. The housing 1 also has a through hole 13 on its wall. One end of the through hole 13 communicates with the side of the mounting hole 11 near the outside of the housing 1, and the other end of the through hole 13 communicates with the outside of the housing 1. The aperture of the through hole 13 is smaller than that of the mounting hole 11. There are multiple through holes 13, which are spaced apart and arranged around the periphery of the mounting hole 11. Specifically, the first sub-hole 111 and the second sub-hole 112 are both vertical holes extending vertically. Both the first sub-hole 111 and the second sub-hole 112 penetrate the inner surface of the housing 1, but neither penetrates the outer surface of the housing 1. The first sub-hole 111 and the second sub-hole 112 are connected by a groove 121. There are two conducting holes 13, one of which is connected to the side of the first sub-hole 111 near the outside of the housing 1 at one end and to the outside of the housing 1 at the other end. The other conducting hole 13 is connected to the side of the second sub-hole 112 near the outside of the housing 1 at one end and to the outside of the housing 1 at the other end. The aperture of the conducting hole 13 is smaller than the aperture of the first sub-hole 111 and the aperture of the second sub-hole 112 (of course, the number of conducting holes 13 can be more). When the fishing boat positioning device falls into the water, external water can enter the mounting hole 11 (including the first sub-hole 111 and the second sub-hole 112) through the conducting hole 13.

[0055] like Figure 12 As shown in FIG. 1 , as an embodiment, the conducting hole 13 is an oblique hole, that is, the conducting hole 13 is tilted, and the angle between the conducting hole 13 and the horizontal direction (that is, the conducting hole 13 and the lower surface of the housing 1) can be 30° to 60°. Figure 13 As shown, as another embodiment, the conducting hole 13 is an L-shaped hole, and the conducting hole 13 includes a first inner hole 131 extending vertically (i.e., perpendicular to the lower surface of the shell 1) and a second inner hole 132 extending laterally (i.e., parallel to the lower surface of the shell 1). One end of the first inner hole 131 is connected to the outside of the shell 1, the other end of the first inner hole 131 is connected to one end of the second inner hole 132, and the other end of the second inner hole 132 is connected to the side of the mounting hole 11 close to the outside of the shell 1. The mounting hole 11 is connected to the outside by setting a conducting hole 13. The aperture of the conducting hole 13 is smaller than the aperture of the mounting hole 11, and the conducting hole 13 is an inclined hole or an L-shaped hole (of course, the conducting hole 13 can also be other non-vertically extending holes), that is, the conducting hole 13 is a non-vertical hole, so that a curved flow channel is formed between the outside of the shell 1 and the mounting hole 11. In rainy weather, the probability of rainwater directly entering the mounting hole 11 can be reduced, thereby reducing the risk of misjudgment (when the fishing boat positioning device falls into the water, since the fishing boat positioning device will be immersed in the water, it will not affect the entry of water).

[0056] like Figures 2 to 6 As shown, as an embodiment, a spring pin 211 is provided on the circuit board 21 and is electrically connected to the circuit board 21. The spring pin 211 is provided corresponding to the water drop detection assembly 3 and is in contact with and electrically connected to the water drop detection assembly 3. That is, the water drop detection assembly 3 is electrically connected to the circuit board 21 via the spring pin 211. Specifically, there are two spring pins 211, which are in contact with and electrically connected to the top of the first conductive member 31 and the top of the second conductive member 32, respectively.

[0057] like Figure 11 As shown, as another embodiment, a buoyancy bar 10 is provided on the outer peripheral wall of the housing 1. The density of the buoyancy bar 10 is less than that of the housing 1. When the fishing boat positioning device falls into the water, the buoyancy bar 10 allows the device to float on the water surface. By providing the buoyancy bar 10, if the fishing boat positioning device accidentally falls into the water alone (falling into the water alone means that the fishing boat positioning device does not fall into the water with the fishing boat. For example, if the fishing boat positioning device falls into the water during installation or in rough weather), the buoyancy bar 10 allows the device to float on the water surface. In this case, the fishing boat positioning device can still function normally, preventing it from sinking directly to the bottom of the water. Subsequent personnel can then salvage the device onto the vessel for continued use. (It should be noted that since the fishing boat positioning device will first submerge in the water and then float to the surface when it falls into the water from a certain height, this will also trigger the water-fall alarm.) The buoyancy bar 10 can be made of polyurethane foam, epoxy foam plastic, etc., and can be solid or hollow. As an embodiment, the housing 1 is a rectangular parallelepiped structure, and the floating rods 10 can be arranged on the outer walls of the housing 1 on opposite sides, or on the outer walls on all four sides. Of course, the housing 1 can also be of other shapes, and the location of the floating rods 10 can be adjusted according to the shape of the housing 1.

[0058] like Figures 1 to 8 As shown in FIG. 1 , as an embodiment, the fishing boat positioning device further includes a battery 20, a solar photovoltaic panel 4, and a transparent cover 5. The battery 20 is disposed within the housing 1. Both the battery 20 and the solar photovoltaic panel 4 are electrically connected to a circuit board 21. The battery 20 is used to power the circuit module 2. The solar photovoltaic panel 4 is electrically connected to the battery 20 via the circuit board 21. The solar photovoltaic panel 4 is used to charge the battery 20. The transparent cover 5 can be made of materials such as transparent plastic and transparent glass.

[0059] The transparent cover 5 is fixedly connected to the outer wall of the shell 1 (specifically, it can be connected by adhesive bonding, screw locking, etc.), and a accommodating chamber 50 is formed between the transparent cover 5 and the outer wall of the shell 1. The accommodating chamber 50 is a sealed cavity, and the accommodating chamber 50 is isolated from the inner cavity of the shell 1, that is, the accommodating chamber 50 and the inner cavity of the shell 1 are not connected to each other, thereby reducing the heat in the accommodating chamber 50 from being transferred to the shell 1 (the transparent cover 5 is exposed to light for a long time, so the temperature in the accommodating chamber 50 is relatively high, and the temperature in the accommodating chamber 50 is generally higher than the temperature in the shell 1). The solar photovoltaic panel 4 is disposed in the accommodating chamber 50, and the solar photovoltaic panel 4 is fixed to the outer wall of the shell 1 (specifically, it can be fixed by screw locking, etc.), that is, the transparent cover 5 seals the solar photovoltaic panel 4; because the transparent cover 5 is a transparent structure, it does not affect the external light from shining on the solar photovoltaic panel 4. A first vent hole 14 is provided on the shell wall of the shell 1. The first vent hole 14 passes through the shell wall of the shell 1. A first waterproof vent valve 141 is provided in the first vent hole 14. The first waterproof vent valve 141 allows air to pass through but does not allow water to pass through. The first waterproof vent valve 141 seals the first vent hole 14 (i.e., the first waterproof vent valve 141 blocks the first vent hole 14).

[0060] The fishing boat positioning device provided in this embodiment comprises a transparent cover 5 disposed on the outer wall of the housing 1, which covers the solar photovoltaic panel 4, thereby protecting the solar photovoltaic panel 4 from corrosion in the humid seawater environment and extending the service life of the solar photovoltaic panel 4. Furthermore, by providing a first air vent 14 in the housing 1 and disposing a first waterproof air vent valve 141 within the first air vent 14, the interior of the housing 1 can be ventilated (i.e., gas exchange) with the external environment through the first waterproof air vent valve 141, thereby maintaining pressure balance inside and outside the housing 1 and preventing a pressure differential between the interior of the housing 1 and the external environment, thereby extending the service life of the housing 1 and the electronic components therein. Furthermore, heat can be exchanged between the interior of the housing 1 and the external environment through the first waterproof air vent valve 141, thereby facilitating heat dissipation within the housing 1 (due to the prolonged exposure of the fishing boat positioning device to light radiation and the heat generated by the electronic components within the housing 1 during operation, the temperature within the housing 1 is generally higher than the temperature of the external environment), thereby extending the service life of the electronic components within the housing 1.

[0061] like Figures 1 to 7As shown, as an embodiment, a wire hole 15 is provided on the shell wall of the shell 1. The wire hole 15 passes through the shell wall of the shell 1 and is provided corresponding to the accommodating cavity 50. The solar photovoltaic panel 4 and the circuit board 21 are electrically connected via a cable (not shown). The cable passes through the wire hole 15, that is, one end of the cable is connected to the solar photovoltaic panel 4, and the other end of the cable is connected to the circuit board 21 after passing through the wire hole 15. The solar photovoltaic panel 4 covers the wire hole 15, that is, the solar photovoltaic panel 4 can seal the wire hole 15, thereby preventing the accommodating cavity 50 from communicating with the inner cavity of the shell 1 through the wire hole 15, thereby reducing or preventing the heat in the accommodating cavity 50 from being conducted into the shell 1 through the wire hole 15.

[0062] like Figures 1 to 7 As shown, as an embodiment, a positioning groove 16 is provided on the outer wall of the housing 1, and the wire hole 15 is provided corresponding to the positioning groove 16, that is, the wire hole 15 is connected to the positioning groove 16; the solar photovoltaic panel 4 is provided in the positioning groove 16, and the size of the positioning groove 16 is adapted to the size of the solar photovoltaic panel 4. The outer wall of the solar photovoltaic panel 4 and the inner wall of the positioning groove 16 are tightly fitted, thereby reducing or preventing the heat in the accommodating cavity 50 from entering the wire hole 15 through the gap between the outer wall of the solar photovoltaic panel 4 and the inner wall of the positioning groove 16. In this embodiment, the solar photovoltaic panel 4 and the positioning groove 16 are both rectangular structures, that is, the solar photovoltaic panel 4 is a block-shaped structure, and the positioning groove 16 is a square groove. The length and width of the solar photovoltaic panel 4 are the same or similar to the length and width of the positioning groove 16.

[0063] like Figure 15 Shown and combined Figure 3 In another embodiment, a thermal insulation film 41 is provided on the inner wall of the positioning groove 16. The thermal insulation film 41 is sandwiched between the inner wall of the positioning groove 16 and the solar photovoltaic panel 4. The two sides of the thermal insulation film 41 are respectively in contact with the inner wall of the positioning groove 16 and the solar photovoltaic panel 4. Holes are opened in the thermal insulation film 41 at locations corresponding to the wire holes 15 to facilitate wiring. Specifically, the thermal insulation film 41 can be a polyester film, a polyamide film, a polyethylene film, a polypropylene film, a polyvinyl chloride film, an aerogel film, or the like. On the one hand, the thermal insulation film 41 can play a role of insulation, reducing the heat in the accommodating cavity 50 from being conducted to the shell 1; on the other hand, when the thermal insulation film 41 is a soft film, it can play a filling role, that is, reducing or eliminating the gap between the outer wall of the solar photovoltaic panel 4 and the inner wall of the positioning groove 16, further reducing the conduction of heat; on the other hand, when the thermal insulation film 41 is a soft film, it can play a shock-absorbing role on the solar photovoltaic panel 4, thereby reducing the risk of damage to the solar photovoltaic panel 4 under long-term vibration (because the fishing boat will constantly rise and fall with the sea surface when sailing on the sea, so the fishing boat positioning device will be subjected to long-term vibration).

[0064] like Figure 16As shown in the figure, as another embodiment, the transparent cover 5 is provided with a second air vent 53 that passes through the transparent cover 5. A second waterproof air valve 531 is provided within the second air vent 53. The second waterproof air valve 531 allows air to pass through but not water, and seals the second air vent 53 (i.e., the second waterproof air valve 531 blocks the second air vent 53). The provision of the second waterproof air valve 531 allows ventilation between the interior of the transparent cover 5 (i.e., the accommodating chamber 50) and the external environment through the second waterproof air valve 531, thereby maintaining pressure balance inside and outside the transparent cover 5 and preventing a pressure differential between the interior and the external environment. Furthermore, heat exchange between the interior of the transparent cover 5 and the external environment occurs through the second waterproof air valve 531, facilitating heat dissipation within the transparent cover 5 and, in turn, extending the lifespan of the transparent cover 5 and the solar photovoltaic panel 4 (due to prolonged exposure to light radiation, the temperature and pressure inside the transparent cover 5 are relatively high).

[0065] Specifically, the transparent cover 5 includes an integrally connected flat plate portion 51 and side portions 52. The flat plate portion 51 is spaced apart and arranged opposite to the solar photovoltaic panel 4. The side portions 52 are formed by bending and extending the edge of the flat plate portion 51 toward the side closest to the housing 1. The side portions 52 are arranged around the periphery of the solar photovoltaic panel 4 and are fixedly connected to the outer wall of the housing 1. The accommodating cavity 50 is formed between the flat plate portion 51, the side portions 52, and the outer wall of the housing 1. The second air vent 53 is provided on the side portion 52 to reduce the effect of the second waterproof air vent 531 on the solar photovoltaic panel 4 receiving light. (Since sunlight generally shines on the solar photovoltaic panel 4 through the flat plate portion 51, if the second air vent 53 is provided on the flat plate portion 51, that is, the second waterproof air vent 531 is provided on the flat plate portion 51, the light received by the solar photovoltaic panel 4 will be blocked, affecting the efficiency of solar power generation.)

[0066] like Figures 2 to 10 As shown, as an embodiment, the fishing boat positioning device further includes a heat dissipation module 6 ( Figure 3The heat dissipation module 6 is not shown in the figure). The heat dissipation module 6 includes a fan 61, which is arranged in the housing 1. The fan 61 can be arranged on the circuit board 21. The fan 61 can specifically be an axial fan or a centrifugal fan. The circuit module 2 also includes a temperature sensor 25, which is arranged in the housing 1. The temperature sensor 25 can be arranged on the circuit board 21. The temperature sensor 25 is used to detect the temperature in the housing 1. The temperature sensor 25 and the fan 61 are both electrically connected to the circuit board 21, and the temperature sensor 25 and the fan 61 are both electrically connected to the control module 24. The shell wall of the housing 1 is provided with air outlet holes 171 and air inlet holes 172 at intervals. The air outlet holes 171 and the air inlet holes 172 are arranged close to each other. The fan 61 is arranged corresponding to the air outlet holes 171, and the fan 61 and the air outlet holes 171 are spaced apart. When the fan 61 is in operation, it can blow air into the air outlet holes 171.

[0067] When the temperature sensor 25 detects that the temperature inside the housing 1 reaches a first preset value (e.g., 45°C), the control module 24 controls the fan 61 to turn on to dissipate heat. Specifically, when the fan 61 turns on, it exhausts the hot air inside the housing 1 through the air outlet 171 while simultaneously drawing cooler air outside the housing 1 into the housing 1 through the air inlet 172. This ensures ventilation and heat dissipation within the housing 1, thereby improving the lifespan of the electronic components within the housing 1. When the temperature sensor 25 detects that the temperature inside the housing 1 drops below a set value (e.g., 40°C), the control module 24 controls the fan 61 to turn off. The set value is lower than the first preset value.

[0068] like Figures 2 to 10 As shown, as one embodiment, the heat dissipation module 6 further includes a motor 62 and a baffle 64. Both motor 62 and baffle 64 are disposed within the housing 1. Specifically, motor 62 can be disposed on the circuit board 21. Baffle 64 is disposed corresponding to the air outlet 171 and the air inlet 172. Baffle 64 is located between the air outlet 171 and the fan 61, abuts against the inner wall of the housing 1, and is movable relative to the housing 1. Motor 62 is electrically connected to the circuit board 21 and electrically connected to the control module 24. Motor 62 is connected to baffle 64 via a transmission mechanism 63. Motor 62 is configured to drive baffle 64 to move (i.e., motor 62 can drive baffle 64 to move via transmission mechanism 63). This allows air outlet 171 and air inlet 172 to be opened during heat dissipation, and to be closed (sealed) after heat dissipation is complete.

[0069] Specifically, in this embodiment, the transmission mechanism 63 is a rack-and-pinion transmission mechanism, comprising a gear 631 and a rack 632. The gear 631 is rotatably connected to the inner wall of the housing 1 and meshes with the rack 632. The output shaft of the motor 62 is fixedly connected to the gear 631, and one end of the rack 632 is fixedly connected to the baffle 64. When the motor 62 is running, the motor 62 drives the gear 631 to rotate, which in turn drives the rack 632 to move, thereby driving the baffle 64 to move (i.e., the transmission mechanism 63 converts the rotational motion of the motor 62 into linear motion). Of course, in other embodiments, the transmission mechanism 63 can also be a synchronous belt transmission mechanism, etc. Furthermore, the baffle 64 can be connected to the inner wall of the housing 1 via a slide rail assembly (not shown) to define the movement path of the baffle 64 and reduce resistance to the movement of the baffle 64. During operation, when the temperature sensor 25 detects that the temperature inside the shell 1 reaches a first preset value, the control module 24 controls the motor 62 to operate to drive the baffle 64 to move and open the air outlet 171 and the air inlet 172. At the same time, the control module 24 controls the fan 61 to turn on to perform heat dissipation work; when the temperature sensor 25 detects that the temperature inside the shell 1 drops to less than the set value, the control module 24 controls the fan 61 to turn off, and at the same time controls the motor 62 to reverse, so as to drive the baffle 64 to move in the opposite direction and block the air outlet 171 and the air inlet 172, thereby preventing external moisture, dust, etc. from entering the shell 1 through the air outlet 171 and the air inlet 172.

[0070] As an embodiment, a charging switch 28 is provided on the circuit board 21, and the solar photovoltaic panel 4 is electrically connected to the circuit board 21 through the charging switch 28, and the charging switch 28 is electrically connected to the control module 24. The charging switch 28 can be specifically an electromagnetic switch, a MOSFET switch circuit, etc.

[0071] When the temperature sensor 25 detects that the temperature inside the housing 1 reaches a second preset value (e.g., 55°C), the control module 24 controls the charging switch 28 to close, disconnecting the solar photovoltaic panel 4 from the circuit board 21 and the battery 20, thereby stopping the solar photovoltaic panel 4 from charging the battery 20 and preventing damage to the battery 20 caused by high-temperature charging. The second preset value is greater than the first preset value. When the temperature sensor 25 detects that the temperature inside the housing 1 drops below the second preset value, the control module 24 controls the charging switch 28 to open again to resume charging.

[0072] like Figures 2 to 10As shown, as an embodiment, the fishing vessel positioning device further includes a disassembly detection module 7. A switch assembly 26 is provided on the circuit board 21. The disassembly detection module 7 is electrically connected to the circuit board 21 via the switch assembly 26. Both the disassembly detection module 7 and the switch assembly 26 are electrically connected to the control module 24 (the disassembly detection module 7 is electrically connected to the control module 24 via the switch assembly 26 and the circuit board 21). The switch assembly 26 may specifically be an electromagnetic switch, a MOSFET switch circuit, or the like. The disassembly detection module 7 is configured to trigger and send an electrical signal to the control module 24 when the fishing vessel positioning device is removed from a fixed component. Upon receiving the electrical signal, the control module 24 transmits a disassembly alarm message to the cloud platform 91 via the communication module 22. The cloud platform 91 then transmits the disassembly alarm message to the administrator's mobile terminal 92 (for example, the control module 24 may send a message such as "Positioning terminal suspected of disassembly" to the mobile terminal 92 via the communication module 22 and the cloud platform 91 to alert the administrator).

[0073] The control module 24 is used to control the opening and closing of the switch assembly 26, thereby connecting or disconnecting the disassembly detection module 7 from the circuit board 21. The fishing vessel positioning device has an operating state (i.e., normal operation) and an installed state (i.e., debugging and installation state). When the fishing vessel positioning device is in the installed state, the control module 24 controls the switch assembly 26 to close upon receiving a forced alarm release signal. When the fishing vessel positioning device is in the operating state, the control module 24 controls the switch assembly 26 to open upon receiving an alarm execution signal. (These forced alarm release and alarm execution signals are generally issued by the mobile terminal 92, which transmits these signals to the control module 24 via the cloud platform 91 and the communication module 22.)

[0074] The fishing boat positioning device provided in this embodiment is provided with a disassembly detection module 7. When the fishing boat positioning device is disassembled from the fixed components of the fishing boat, the disassembly detection module 7 is triggered, and then the control module 24 sends a disassembly alarm information to the cloud platform 91 through the communication module 22. The cloud platform 91 then sends the disassembly alarm information to the administrator's mobile terminal 92, so that the administrator is informed in time that the fishing boat positioning device has been disassembled privately, thereby realizing the disassembly alarm function of the fishing boat positioning device and improving the safety of the fishing boat.

[0075] Since the fishing boat positioning device needs to be debugged during installation (at this time the fishing boat positioning device has not been installed on the fixed part), if the disassembly alarm function is normally opened at this time, it will cause the disassembly detection module 7 to frequently trigger the alarm (false alarm), affecting the debugging operation, and interfering with the judgment of the background administrator. Therefore, the embodiment also sets a switch assembly 26, when the fishing boat positioning device is in the installation state, the control module 24 controls the switch assembly 26 to be closed after receiving the forced alarm removal signal based on the mobile terminal 92, so that the disassembly detection module 7 is disconnected with the circuit board 21, and then the disassembly alarm function is closed, to avoid false alarm; when the fishing boat positioning device is in a normal working state, the control module 24 controls the switch assembly 26 to be opened after receiving the alarm execution signal based on the mobile terminal 92, so that the disassembly detection module 7 is connected with the circuit board 21, and then the normal disassembly alarm function is restored (for example, the mobile terminal 92 is provided with the options of "opening the disassembly alarm function" and "closing the disassembly alarm function", when the administrator selects the option of "closing the disassembly alarm function", the forced alarm removal signal is generated; when the administrator selects the option of "opening the disassembly alarm function", the alarm execution signal is generated).

[0076] As shown in Figures 2 to 7 and Figure 10 , as an embodiment, the disassembly detection module 7 includes a light sensor 71 and a transparent light guide 72; the light sensor 71 is arranged on the circuit board 21 and is electrically connected with the circuit board 21 through the switch assembly 26, and the light sensor 71 is electrically connected with the control module 24. The shell wall of the shell 1 is provided with a containing hole 181 penetrating through the shell wall of the shell 1, the containing hole 181 is arranged corresponding to the light sensor 71, the light guide 72 is arranged in the containing hole 181, and the light guide 72 seals the containing hole 181; the light guide 72 is specifically a light guide column. On the one hand, the light guide 72 plays a role of light guide, and the external light can be conducted to the light sensor 71 through the light guide 72; on the other hand, the light guide 72 can play a role of sealing the containing hole 181, so as to avoid that the external water vapor, dust and the like enter into the shell 1 through the containing hole 181.

[0077] When the fishing boat positioning device is removed from the fixed component, the light guide 72 is exposed, allowing the light guide 72 to transmit external light to the light sensor 71. After receiving the external light, the light sensor 71 can convert the light signal into an electrical signal and send it to the control module 24, which then executes the disassembly alarm action. Specifically, when the fishing boat positioning device is not removed from the fixed component, the light guide 72 is close to the fixed component. The external light cannot be irradiated onto the light guide 72 due to the obstruction of the fixed component, and thus cannot be transmitted to the light sensor 71. When the fishing boat positioning device is removed from the fixed component, the light guide 72 loses the obstruction of the fixed component and is exposed. At this time, the external light will irradiate the light guide 72, and then be transmitted to the light sensor 71 and trigger the disassembly alarm.

[0078] like Figures 2 to 7 and Figure 10 As shown, as an embodiment, the disassembly detection module 7 further includes a Hall sensor 73 and a magnetic block 74. The magnetic block 74 may specifically be a magnet, such as a magnet or magnetic steel. The Hall sensor 73 is disposed on the circuit board 21 and electrically connected to the circuit board 21 via the switch assembly 26. The Hall sensor 73 is electrically connected to the control module 24. A receiving groove 182 is provided on the outer wall of the housing 1. The receiving groove 182 does not penetrate the wall of the housing 1. The receiving groove 182 is provided corresponding to the Hall sensor 73. The magnetic block 74 is movably disposed within the receiving groove 182 and is used to be magnetically fixed to the fixed component (it should be noted that when the magnetic block 74 is magnetically fixed to the fixed component, a portion of the magnetic block 74 is located within the receiving groove 182).

[0079] When the fishing boat positioning device is removed from the fixed component, the magnetic block 74 escapes from the receiving slot 182 and the distance between it and the Hall sensor 73 exceeds the preset range. The Hall sensor 73 generates an electrical signal and sends it to the control module 24. Specifically, the Hall sensor 73 is an electronic switch that uses a magnetic field as a sensor to control the device by detecting changes in magnetic field strength. It is a non-contact switch that can detect the presence of an object. The principle of the Hall sensor 73 is that it has a built-in magnet and a miniature electronic component. When it approaches an external magnetic field, it generates a voltage. In this embodiment, when the fishing boat positioning device is not removed from the fixed component, the magnetic block 74 is adsorbed on the fixed component, and the distance between the magnetic block 74 and the Hall sensor 73 is relatively close. At this time, the Hall sensor 73 outputs a low level to the control module 24; when the fishing boat positioning device is removed from the fixed component, since the magnetic block 74 is adsorbed on the fixed component, the fishing boat positioning device will move away from the fixed component, causing the magnetic block 74 and the Hall sensor 73 to move away from each other, and the distance between the two exceeds the preset range. At this time, the Hall sensor 73 outputs a high level to the control module 24 (that is, a level change occurs), thereby triggering the disassembly alarm.

[0080] Since the light sensor 71 alarm will fail when the light is dim at night (the light is weak at night, even if the fishing boat positioning device is disassembled, the light sensor 71 alarm will not be triggered), the Hall sensor 73 alarm is set to supplement, that is, either the light sensor 71 or the Hall sensor 73 will trigger the alarm to ensure safety.

[0081] As shown in Figures 1 to 7 As an embodiment, the water falling detection assembly 3 and the disassembly detection module 7 are located on the same side of the shell 1, and the water falling detection assembly 3 and the solar photovoltaic panel 4 are located on opposite sides of the shell 1. Specifically, the shell 1 has a mounting surface 100, the mounting hole 11, the first air hole 14, the accommodating hole 181 and the accommodating groove 182 are arranged on the shell wall where the mounting surface 100 is located, and the positioning groove 16 is arranged on the outer wall of the shell 1 away from the mounting surface 100. During installation, the mounting surface 100 is vertically downward or obliquely downward, and the angle between the mounting surface 100 and the horizontal direction can be 0°-60°.

[0082] The fishing boat positioning device further comprises a mounting assembly 8 arranged on opposite sides of the shell 1; the mounting assembly 8 comprises a mounting plate 81 which is attached to the mounting surface 100 and fixedly connected with the shell 1, the mounting plate 81 protrudes from the mounting surface 100, and the mounting plate 81 is used for fixedly connecting with the fixed component.

[0083] Specifically, the mounting assembly 8 further comprises a first fixing member 82, a buffer pad 83 and a second fixing member 84, the mounting plate 81 is fixedly connected with the shell 1 through the first fixing member 82, and the mounting plate 81 is fixedly connected with the fixed component through the second fixing member 84; the first fixing member 82 and the second fixing member 84 are both screws. The buffer pad 83 is arranged between the first fixing member 82 and the mounting plate 81 and / or between the mounting plate 81 and the mounting surface 100 (in this embodiment, the buffer pad 83 is arranged between the head of the first fixing member 82 and the mounting plate 81), and the buffer pad 83 can play a shock-absorbing role, thereby reducing the risk of damage to the fishing boat positioning device under long-term vibration.

[0084] As shown in Figures 1 to 7 As an embodiment, the accommodating hole 181 is arranged corresponding to the mounting plate 81, the mounting plate 81 covers the accommodating hole 181, and a light hole 811 is arranged on the mounting plate 81 corresponding to the position of the accommodating hole 181; in this way, the mounting plate 81 can block the lateral light, reducing the risk of false alarm caused by the external light shining on the light guide member 72 through the gap between the mounting surface 100 and the fixed component. The accommodating groove 182 is arranged away from the mounting plate 81, that is, the mounting plate 81 does not cover the accommodating groove 182.

[0085] The light passing hole 811 and the accommodating hole 181 are both circular holes, the diameter of the light passing hole 811 is greater than the diameter of the accommodating hole 181, a circular ring-shaped light shielding ring 75 is arranged in the light passing hole 811, the light shielding ring 75 is fixed to the inner wall of the light passing hole 811 (specifically, the light shielding ring 75 can be fixed by adhesive bonding), and the inner diameter of the light shielding ring 75 is greater than or equal to the diameter of the accommodating hole 181. The light shielding ring 75 can be a black rubber ring that can absorb lateral light. By arranging the light shielding ring 75, the light shielding ring 75 can further shield lateral light (there can be a gap between the mounting plate 81 and the fixed part, and external light can pass through the gap between the two to laterally irradiate the light guide 72, causing false alarms); and because the inner diameter of the light shielding ring 75 is greater than or equal to the diameter of the accommodating hole 181, when the fishing boat positioning device is disassembled, the light shielding ring 75 will not shield external light from irradiating the light guide 72.

[0086] As shown in Figure 14 as another embodiment, a magnetic light shielding piece 76 is movably arranged in the light passing hole 811, the magnetic light shielding piece 76 is a circular block structure, the outer diameter of the magnetic light shielding piece 76 is greater than or equal to the diameter of the accommodating hole 181, and the magnetic light shielding piece 76 can be a magnet, a magnetic steel or the like, and the magnetic light shielding piece 76 is used to be magnetically attracted and fixed to the fixed part; when the fishing boat positioning device is disassembled from the fixed part, the magnetic light shielding piece 76 is detached from the light passing hole 811. Specifically, when the fishing boat positioning device is not disassembled, the magnetic light shielding piece 76 is located in the light passing hole 811, and the magnetic light shielding piece 76 can shield external light to avoid false alarms; when the fishing boat positioning device is disassembled from the fixed part, the magnetic light shielding piece 76 is magnetically attracted and fixed to the fixed part, at this time the magnetic light shielding piece 76 is detached from the light passing hole 811, and external light can pass through the light passing hole 811 to irradiate the light guide 72.

[0087] As an embodiment, the circuit module 2 further comprises an acceleration sensor 27 arranged in the housing 1, the acceleration sensor 27 can be arranged on the circuit board 21, the acceleration sensor 27 is electrically connected to the circuit board 21 through the switch assembly 26, the acceleration sensor 27 is electrically connected to the control module 24, and the acceleration sensor 27 is used to detect the acceleration signal of the fishing boat positioning device; when the acceleration sensor 27 detects that the acceleration signal value of the fishing boat positioning device exceeds a preset value, the control module 24 sends a capsizing alarm information to the cloud platform 91 through the communication module 22, and the cloud platform 91 sends the capsizing alarm information to the mobile terminal 92 of the administrator, so as to realize the capsizing alarm function.

[0088] Specifically, the acceleration sensor 27 (i.e. G-sensor) is a sensor for estimating the speed and displacement of an object by measuring the acceleration of the object. The acceleration sensor 27 can detect the change of the acceleration force of the object (the acceleration force is the force acting on the object during acceleration, such as shaking, falling, rising, falling, and various changes in movement, which can be converted into an electrical signal by the G-sensor), measure the acceleration and inclination angle of the object. The control module 24 determines whether the fishing boat has capsized, overturned, etc. by determining whether the acceleration signal value detected by the acceleration sensor 27 exceeds the preset value. In this embodiment, the acceleration sensor 27 is a six-axis sensor, and when the acceleration sensor 27 detects that the acceleration in the XYZ direction exceeds the threshold value, the control module 24 determines that the fishing boat has capsized, overturned.
