Description

Technical Field

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

[0002] A positioning device is a device that uses satellite positioning and uploads the obtained positioning data to a server through a mobile communication module (GSM / GPRS network). Positioning devices are generally used to be installed on vehicles, ships, etc. Positioning devices generally have a positioning module and a communication module. The positioning module is used to obtain the location information of the positioning device, and then the communication module transmits the location information obtained by the positioning module to the cloud server. Users use their mobile terminal devices (such as mobile phones) to interact with the cloud server to obtain the location information of the positioning device, thereby obtaining the location information of vehicles, ships, etc. to ensure the safety of vehicles and ships.

[0003] In order to monitor the safety of fishing boats, fishing boats are generally equipped with fishing boat positioning devices. Since fishing boats sail on the sea, it is inconvenient to power the fishing boat positioning devices. Therefore, current fishing boat positioning devices are generally equipped with solar photovoltaic panels to charge the batteries. However, current fishing boat positioning devices have the following problems during use:

[0004] 1. Solar photovoltaic panels are generally installed naked on the outer wall of the shell of the fishing boat positioning device. Since solar photovoltaic panels are easily corroded by the humid seawater environment, they are easily damaged and have a short service life.

[0005] 2. In order to allow the solar photovoltaic panels to receive sufficient light, the fishing boat positioning device is generally installed outside the cabin (for example, on the deck), so that the fishing boat positioning device can be exposed to sunlight from morning to night. At the same time, in order to prevent external water vapor and dust from entering the shell of the fishing boat positioning device, the shell is generally a sealed structure. However, during the operation of the fishing boat positioning device, since the fishing boat positioning device is exposed to light radiation for a long time and the electronic components inside the shell generate heat when working, the temperature inside the shell is generally higher than the temperature of the external environment. Under the action of high temperature, the air in the shell will expand, making the air pressure inside the shell higher than the air pressure of the external environment, that is, there will be a pressure difference between the inside of the shell and the outside world. Under the action of this pressure difference, the damage of the shell and the electronic components inside the shell will be accelerated. Summary of the invention

[0006] An object of the present invention is to provide a fishing boat positioning device that can improve the life of solar photovoltaic panels and electronic components inside the casing.

[0013] In an implementable manner, the transparent cover includes an integrally connected flat plate portion and a side portion. The flat plate portion is arranged opposite to the solar photovoltaic panel at an interval. The side portion is bent and extended from the edge of the flat plate portion towards the side close to the housing. The side portion surrounds the periphery of the solar photovoltaic panel, and the side portion is fixedly connected to the outer wall of the housing. The second ventilation hole is provided on the side portion.

[0015] When the temperature sensor detects that the temperature inside the housing reaches a first preset value, the control module controls the fan to turn on to perform heat dissipation work.

[0016] In an implementable manner, the heat dissipation module further includes a motor and a baffle, the baffle is disposed corresponding to the air outlet holes and the air inlet holes, the baffle is attached to the inner wall of the housing, and the baffle can move relative to the housing; the motor is electrically connected to the circuit board, and the motor is electrically connected to the control module in an electrical signal manner; the motor is connected to the baffle through a transmission mechanism, and the motor is used to drive the baffle to move to open the air outlet holes and the air inlet holes when performing heat dissipation work, and close the air outlet holes and the air inlet holes after the heat dissipation work is completed.

[0039] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0040] The terms "first", "second", "third", etc. (if any) in the description and claims of the present invention are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0041] The orientation terms such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the description and claims of the present invention are defined based on the positions of the structures in the drawings and the positions of the structures relative to each other, only for the sake of clarity and convenience of expressing the technical solution. It should be understood that the use of orientation terms should not limit the scope of protection requested by the present invention.

[0042] Such as Figures 1 to 10As shown in the figure, an embodiment of the present invention provides a fishing boat positioning device for being installed on a fixed component (not shown in the figure) of a fishing boat, and the fixed component can be a structural component such as the deck or mast of the fishing boat. The fishing boat positioning device includes a housing 1, a circuit module 2, and a water immersion detection component 3. The housing 1 is a sealed structure, and the circuit module 2 is arranged inside 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 arranged on the circuit board 21 and are all electrically connected to the circuit board 21. The water immersion detection component 3 is electrically connected to the circuit board 21, and the water immersion detection component 3, the communication module 22, and the positioning module 23 are all electrically connected to the control module 24 in an electrical signal connection manner (specifically, the water immersion detection component 3, the communication module 22, and the positioning module 23 are all electrically connected to the control module 24 through the circuit board 21 in an electrical signal connection manner). Among them, the communication module 22 is used for wireless communication, the positioning module 23 is used for receiving positioning information, and the control module 24 is used for wirelessly transmitting the positioning information received by the positioning module 23 to the cloud platform 91 (i.e., the cloud server) through the communication module 22. A mobile terminal 92 (such as a mobile phone, a computer, etc.) of a fishing boat administrator can perform data interaction with the cloud platform 91 to obtain the positioning information (the specific functions and working principles of the communication module 22 and the positioning module 23 can refer to the prior art and will not be elaborated here).

[0043] An installation hole 11 is provided on the housing wall of the housing 1. The installation hole 11 is simultaneously communicated with the inner cavity of the housing 1 and the outside of the housing 1. At least a part of the water immersion detection component 3 is arranged in the installation hole 11 and blocks the installation hole 11, so as to prevent external water, dust, etc. from entering the housing 1 through the installation hole 11. Among them, since the installation hole 11 is communicated with the inner cavity of the housing 1, it is convenient for the water immersion detection component 3 to be electrically connected to the circuit board 21; since the installation hole 11 is communicated with the outside of the housing 1, external water can enter the installation hole 11.

[0044] When the fishing boat positioning device falls into the water, the water outside the housing 1 can enter the mounting hole 11 to turn on the water ingress detection component 3. The control module 24 sends a water ingress alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the water ingress alarm message to the mobile terminal 92 of the administrator (for example, the control module 24 can send information such as "the fishing boat is 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 does not fall into the water, since the water ingress detection component 3 is not in contact with water, the water ingress detection component 3 is in an off state. At this time, the control module 24 does not send a water ingress alarm message to the cloud platform 91 through the communication module 22; when the fishing boat positioning device falls into the water, the outside water will enter the mounting hole 11. After the water ingress detection component 3 comes into contact with water, it conducts and generates an electrical signal. The water ingress detection component 3 transmits this electrical signal to the control module 24, and the control module 24 sends a water ingress alarm message to the cloud platform 91 through the communication module 22 after receiving the electrical signal.

[0045] For the fishing boat positioning device provided in this embodiment, by setting the water ingress detection component 3, when the fishing boat positioning device falls into the water, the water outside the housing 1 can enter the mounting hole 11 to turn on the water ingress detection component 3. Then, the control module 24 sends a water ingress alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the water ingress alarm message to the mobile terminal 92 of the administrator, so that the administrator can timely learn about the fishing boat capsizing and falling into the water accident, realizing the water ingress alarm function of the fishing boat positioning device and improving the safety of the fishing boat.

[0046] Such as Figure 2 , Figure 5 and Figure 6As shown, as an implementation manner, the outer end of the water ingress detection component 3 (i.e., the end of the water ingress detection component 3 close to the outer side of the housing 1) is spaced from the outer surface of the housing 1. That is, the lower end of the water ingress detection component 3 is located above the lower surface of the housing 1. In other words, the water ingress detection component 3 is completely located within the mounting hole 11. Such a setting can reduce the risk of misjudgment caused by the water ingress detection component 3 being turned on after contacting the water on the surface of the housing 1 under non-water ingress conditions when there is water on the surface of the housing 1 (for example, in rainy weather). If the outer end of the water ingress detection component 3 is exposed outside the mounting hole 11 or the outer end of the water ingress detection component 3 is flush with the outer surface of the housing 1, when there is water on the surface of the housing 1, the water will directly contact the water ingress detection component 3. Since the outer end of the water ingress detection component 3 is spaced from the outer surface of the housing 1, that is, there is a height difference between the outer end of the water ingress detection component 3 and the outer surface of the housing 1. When there is a small amount of water on the surface of the housing 1, the water on the surface of the housing 1 will not directly contact the water ingress detection component 3, thereby reducing the risk of misjudgment. As an implementation manner, the height difference between the outer end of the water ingress 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.

[0047] As Figures 2 to 6 and Figure 10 shown, as an implementation manner, the water ingress detection component 3 includes a first conductive member 31 and a second conductive member 32. Both the first conductive member 31 and the second conductive member 32 are electrically connected to the control module 24. The mounting hole 11 includes a first sub-hole 111 and a second sub-hole 112 that are spaced apart. The first conductive member 31 is disposed in the first sub-hole 111 and blocks the first sub-hole 111. The second conductive member 32 is disposed in the second sub-hole 112 and blocks the second sub-hole 112. When the fishing boat positioning device falls into the water, the water outside the housing 1 can enter the first sub-hole 111 and the second sub-hole 112 respectively, so that the first conductive member 31 and the second conductive member 32 are electrically connected through the water.

[0048] Specifically, in this embodiment, the water immersion detection component 3 further includes a current detection circuit 33 disposed on the circuit board 21. The current detection circuit 33 is electrically connected to the circuit board 21, and is respectively electrically connected to the first conductive member 31, the second conductive member 32, and the control module 24 (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 electrically connected through water, a current loop is formed among 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, and after receiving the electrical signal, the control module 24 sends a water immersion alarm message to the cloud platform 91 through the communication module 22. The current detection circuit 33 may specifically include a resistor. The first conductive member 31, the resistor, and the second conductive member 32 are connected in series. The control module 24 is connected to both ends of the resistor. When the first conductive member 31 and the second conductive member 32 are electrically connected, a voltage signal is generated at both ends of the resistor (when the first conductive member 31 and the second conductive member 32 are disconnected, there is no voltage at both ends of the resistor). After receiving the voltage signal, the control module 24 sends a water immersion alarm message to the cloud platform 91 through the communication module 22. Of course, in other embodiments, the current detection circuit 33 may also be in other structural forms (for example, the current detection circuit 33 includes a current induction switch, an electromagnetic switch, a Mos transistor switch circuit, etc.). In other embodiments, the water immersion detection component 3 may also adopt other structures.

[0049] Such as Figures 2 to 6As shown, as an implementation manner, the first sub-hole 111 and the second sub-hole 112 are arranged close to each other, and a partition portion 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 provided on one side of the partition portion 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 communicate with each other through the groove 121; the outer end portion of the first conductive member 31 (that is, the end portion of the first conductive member 31 close to the outside of the shell 1) and the outer end portion of the second conductive member 32 (that is, the end portion of the second conductive member 32 close to the outside of the shell 1) are both located on the side of the bottom 1210 of the groove 121 close to the inner cavity of the shell 1, that is, the lower end portions of the first conductive member 31 and the second conductive member 32 are both located above the groove 121. Among them, by arranging the outer end portions of the first conductive member 31 and the second conductive member 32 at intervals from the outer surface of the shell 1 (that is, the first conductive member 31 is completely located in the first sub-hole 111, and the second conductive member 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 member 31 and the second conductive member 32 to make the two conduct, 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 member 31 and the second conductive member 32 is shortened, the creepage distance between the two is reduced. At the same time, by providing the groove 121, the creepage distance between the first conductive member 31 and the second conductive member 32 can be further reduced, and the creepage distance between the first conductive member 31 and the second conductive member 32 can be controlled by adjusting the depth of the groove 121; in this way, not only can the first conductive member 31 and the second conductive member 32 be more easily conducted after the fishing boat positioning device falls into the water, improving the sensitivity of the water entry detection (even in river water with a low conductivity, the first conductive member 31 and the second conductive member 32 can be conducted. After testing, if the creepage distance between the first conductive member 31 and the second conductive member 32 is large, the first conductive member 31 and the second conductive member 32 can be conducted in seawater with a high conductivity, but cannot be conducted or are not sensitive in river water with a low conductivity), but also the risk of misjudgment caused by the creepage distance between the first conductive member 31 and the second conductive member 32 being too close in rainy weather can be reduced. As an implementation manner, the depth of the groove 121 can be 1 mm to 4 mm, or 2 mm to 3 mm.

[0050] As Figures 2 to 6As shown, as an implementation manner, both the first sub-hole 111 and the second sub-hole 112 are cylindrical holes, both the first conductive member 31 and the second conductive member 32 are cylindrical electrode posts, 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. The first conductive member 31 and the inner wall of the first sub-hole 111 can be fixed by snap connection, interference fit, etc., and sealant can also 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. The second conductive member 32 and the inner wall of the second sub-hole 112 can be fixed by snap connection, interference fit, etc., and sealant can also be provided between the outer wall of the second conductive member 32 and the inner wall of the second sub-hole 112.

[0051] Wherein, the shortest distance L between the first sub-hole 111 and the second sub-hole 112 satisfies the following conditions:

[0052] L = k * D; wherein, D is the outer diameter of the first conductive member 31 (the second conductive member 32), and k is a conductive safety factor, and the value range of k is 0.2 to 0.8. Since the creepage distance between the first conductive member 31 and the second conductive member 32 is mainly controlled by the distance between the first sub-hole 111 and the second sub-hole 112, with such a setting, by controlling the distance between the first sub-hole 111 and the second sub-hole 112, the creepage distance between the first conductive member 31 and the second conductive member 32 can be well controlled (to avoid the creepage distance being too small or too large). When the outer diameters of the first conductive member 31 and the second conductive member 32 are larger, their current-carrying areas are also larger (that is, the contact areas of water with the first conductive member 31 and the second conductive member 32 are larger), which means that the first conductive member 31 and the second conductive member 32 are more likely to conduct. At this time, 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 conductive member 31 and the second conductive member 32 are smaller, their current-carrying areas are also smaller, and at this time, the distance between the first sub-hole 111 and the second sub-hole 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.

[0053] Such as Figures 2 to 6As shown, as an implementation manner, a first slot 311 is provided on one side of the first conductive member 31 close to the outside of the housing 1 (that is, an inwardly recessed first slot 311 is provided at the lower end of the first conductive member 31). The first slot 311 is disposed at the central position of the first conductive member 31 and does not penetrate the first conductive member 31; a second slot 321 is provided on one side of the second conductive member 32 close to the outside of the housing 1 (that is, an inwardly recessed second slot 321 is provided at the lower end of the second conductive member 32). The second slot 321 is disposed at the central position of the second conductive member 32 and does not penetrate 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 member 31 and the second conductive member 32 (that is, the contact area between the water and the first conductive member 31 and the second conductive member 32), thereby improving the conduction performance of the first conductive member 31 and the second conductive member 32, and further improving the sensitivity.

[0054] As Figures 2 to 6 shown, as an implementation manner, the mounting hole 11 penetrates the housing wall of the housing 1, and opposite ends of the mounting hole 11 are directly communicated with the inner cavity of the housing 1 and the outside of the housing 1 respectively. That is, both the first sub-hole 111 and the second sub-hole 112 penetrate the housing wall of the housing 1, and opposite ends of the first sub-hole 111 and opposite ends of the second sub-hole 112 are directly communicated with the inner cavity of the housing 1 and the outside of the housing 1 respectively.

[0055] As Figure 12As shown, as another embodiment, the mounting hole 11 is a vertically extending vertical hole that penetrates the inner surface of the housing 1 and does not penetrate the outer surface of the housing 1; a through hole 13 is further provided on the housing wall of the housing 1. One end of the through hole 13 communicates with the side of the mounting hole 11 close to 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 the aperture of the mounting hole 11. The number of the through holes 13 is multiple, and the multiple through holes 13 are arranged at intervals around the mounting hole 11. Specifically, both the first sub-hole 111 and the second sub-hole 112 are vertically extending vertical holes that penetrate the inner surface of the housing 1 and do not penetrate the outer surface of the housing 1, and the first sub-hole 111 and the second sub-hole 112 are connected through a groove 121; the number of the through holes 13 is two. One end of one through hole 13 communicates with the side of the first sub-hole 111 close to the outside of the housing 1 and the other end communicates with the outside of the housing 1, and one end of the other through hole 13 communicates with the side of the second sub-hole 112 close to the outside of the housing 1 and the other end communicates with the outside of the housing 1. The aperture of the through 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 the through holes 13 can also 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 through hole 13.

[0056] As Figure 12 shown, as an embodiment, the through hole 13 is an inclined hole, that is, the through hole 13 is inclined, and the angle between the through hole 13 and the horizontal direction (that is, the through hole 13 and the lower surface of the housing 1) can be 30°-60°. As Figure 13 shown, as another embodiment, the through hole 13 is an L-shaped hole. The through hole 13 includes a first inner hole 131 extending vertically (that is, perpendicular to the lower surface of the housing 1) and a second inner hole 132 extending horizontally (that is, parallel to the lower surface of the housing 1). One end of the first inner hole 131 communicates with the outside of the housing 1, the other end of the first inner hole 131 communicates with one end of the second inner hole 132, and the other end of the second inner hole 132 communicates with the side of the mounting hole 11 close to the outside of the housing 1. By providing the through hole 13 to communicate the mounting hole 11 with the outside, the aperture of the through hole 13 is smaller than the aperture of the mounting hole 11, and the through hole 13 is an inclined hole or an L-shaped hole (of course, the through hole 13 can also be other non-vertically extending holes), that is, the through hole 13 is a non-vertical hole, so that a bent flow channel is formed between the outside of the housing 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 does not affect the entry of water).

[0057] AsFigures 2 to 6 As shown in the figure, as an implementation manner, spring thimbles 211 are provided on the circuit board 21, and the spring thimbles 211 are electrically connected to the circuit board 21; the spring thimbles 211 are arranged corresponding to the water ingress detection component 3, and the spring thimbles 211 are in contact with and electrically connected to the water ingress detection component 3, that is, the water ingress detection component 3 is electrically connected to the circuit board 21 through the spring thimbles 211. Specifically, the number of the spring thimbles 211 is two, and the two spring thimbles 211 are respectively in contact with and electrically connected to the tops of the first conductive member 31 and the second conductive member 32.

[0058] As Figure 11 shown in the figure, as another implementation manner, a floating strip 10 is provided on the outer peripheral wall of the housing 1, and the density of the floating strip 10 is less than that of the housing 1; 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 10. By providing the floating strip 10, when 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 together with the fishing boat. For example, during the installation of the fishing boat positioning device, or in windy and wavey weather, the fishing boat positioning device falls from the fishing boat into the water), the fishing boat positioning device can float on the water surface through the floating strip 10. At this time, the fishing boat positioning device can still work normally, avoiding the fishing boat positioning device from directly sinking to the bottom. Subsequently, the staff can salvage the fishing boat positioning device onto the boat and continue to use it (it should be noted that when the fishing boat positioning device falls into the water from a certain height, it will first be submerged in the water and then float to the water surface, so the water ingress alarm will also be triggered). The material of the floating strip 10 can be polyurethane foam, epoxy foam plastic, etc., and the floating strip 10 can be a solid structure or a hollow structure. As an implementation manner, the housing 1 is a cuboid structure, and the floating strip 10 can be arranged on the outer walls on the opposite sides of the housing 1, or on the outer walls on the four sides, etc. Of course, the housing 1 can also be of other shapes, and the installation position of the floating strip 10 can be adjusted adaptively according to the shape of the housing 1.

[0059] As Figures 1 to 8 shown in the figure, as an implementation manner, the fishing boat positioning device further includes a battery 20, a solar photovoltaic panel 4 and a transparent cover 5. The battery 20 is arranged in the housing 1, and both the battery 20 and the solar photovoltaic panel 4 are electrically connected to the circuit board 21. The battery 20 is used to supply power to the circuit module 2; the solar photovoltaic panel 4 is electrically connected to the battery 20 through the circuit board 21, and the solar photovoltaic panel 4 is used to charge the battery 20. The transparent cover 5 can specifically adopt materials such as transparent plastic and transparent glass.

[0060] The transparent cover 5 is fixedly connected to the outer wall of the housing 1 (specifically, it can be connected by means of glue bonding, screw fastening, etc.). An accommodation cavity 50 is formed between the transparent cover 5 and the outer wall of the housing 1. The accommodation cavity 50 is a sealed cavity, and the accommodation cavity 50 is isolated from the inner cavity of the housing 1, that is, the accommodation cavity 50 and the inner cavity of the housing 1 are not connected to each other, so as to reduce the heat conduction from the accommodation cavity 50 to the inside of the housing 1 (the transparent cover 5 is exposed to light for a long time, so the temperature in the accommodation cavity 50 is relatively high, and the temperature in the accommodation cavity 50 is generally higher than the temperature inside the housing 1). The solar photovoltaic panel 4 is arranged in the accommodation cavity 50 and is fixed on the outer wall of the housing 1 (specifically, it can be fixed by means of screw fastening, etc.), that is, the transparent cover 5 seals and covers the solar photovoltaic panel 4; since the transparent cover 5 is a transparent structure, it does not affect the external light from irradiating on the solar photovoltaic panel 4. A first ventilation hole 14 is provided on the wall of the housing 1. The first ventilation hole 14 penetrates the wall of the housing 1. A first waterproof and breathable valve 141 is arranged in the first ventilation hole 14. The first waterproof and breathable valve 141 allows air to pass through but does not allow water to pass through. The first waterproof and breathable valve 141 seals the first ventilation hole 14 (that is, the first waterproof and breathable valve 141 blocks the first ventilation hole 14).

[0061] For the fishing boat positioning device provided in this embodiment, by arranging the transparent cover 5 on the outer wall of the housing 1, the transparent cover 5 covers the solar photovoltaic panel 4, thus playing a protective role for the solar photovoltaic panel 4, avoiding the corrosion of the solar photovoltaic panel 4 by the humid seawater environment, and prolonging the service life of the solar photovoltaic panel 4. At the same time, by opening the first ventilation hole 14 on the housing 1 and arranging the first waterproof and breathable valve 141 in the first ventilation hole 14, the inside of the housing 1 can exchange air (i.e., gas exchange) with the external environment through the first waterproof and breathable valve 141, so as to ensure the pressure balance inside and outside the housing 1, avoid the generation of pressure difference between the inside of the housing 1 and the external environment, and thus prolong the service life of the housing 1 and the electronic components inside the housing 1; at the same time, the inside of the housing 1 and the external environment can exchange heat (i.e., heat exchange) through the first waterproof and breathable valve 141, which is beneficial to the heat dissipation inside the housing 1 (since the fishing boat positioning device is exposed to light radiation for a long time and the electronic components inside the housing 1 generate heat during operation, the temperature inside the housing 1 is generally higher than the temperature of the external environment), and further beneficial to prolonging the service life of the electronic components inside the housing 1.

[0062] Such as Figures 1 to 7As shown, as an implementation manner, a wire passing hole 15 is provided on the shell wall of the shell 1. The wire passing hole 15 penetrates through the shell wall of the shell 1. The wire passing hole 15 is correspondingly arranged with respect to the accommodation cavity 50. The solar photovoltaic panel 4 and the circuit board 21 are electrically connected through a cable (not shown in the figure). The cable passes through the wire passing hole 15, that is, one end of the cable is connected to the solar photovoltaic panel 4, and the other end of the cable passes through the wire passing hole 15 and is connected to the circuit board 21. The solar photovoltaic panel 4 covers the wire passing hole 15, that is, the solar photovoltaic panel 4 can seal the wire passing hole 15, thereby preventing the accommodation cavity 50 from communicating with the inner cavity of the shell 1 through the wire passing hole 15, and further reducing or avoiding the heat in the accommodation cavity 50 from being conducted to the inside of the shell 1 through the wire passing hole 15.

[0063] As Figures 1 to 7 shown, as an implementation manner, a positioning groove 16 is provided on the outer wall of the shell 1. The wire passing hole 15 is correspondingly arranged with respect to the positioning groove 16, that is, the wire passing hole 15 communicates with the positioning groove 16; the solar photovoltaic panel 4 is arranged in the positioning groove 16. 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 is closely attached to the inner wall of the positioning groove 16, thereby reducing or avoiding the heat in the accommodation cavity 50 from entering the wire passing 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, both the solar photovoltaic panel 4 and the positioning groove 16 are rectangular parallelepiped structures, that is, the solar photovoltaic panel 4 is a square block structure, the positioning groove 16 is a square groove, and the length and width dimensions of the solar photovoltaic panel 4 are the same as or similar to the length and width dimensions of the positioning groove 16.

[0064] As Figure 15 shown and combined with Figure 3 As another implementation manner, a heat insulation film 41 is provided on the inner wall of the positioning groove 16. The heat insulation film 41 is clamped between the inner wall of the positioning groove 16 and the solar photovoltaic panel 4. The two sides of the heat insulation film 41 are respectively attached to the inner wall of the positioning groove 16 and the solar photovoltaic panel 4. An opening needs to be made in the heat insulation film 41 at the position corresponding to the wire passing hole 15 for wiring. The heat insulation film 41 can specifically be a polyester film, a polyamide film, a polyethylene film, a polypropylene film, a polyvinyl chloride film, an aerogel film, etc. On the one hand, the heat insulation film 41 can play a heat insulation role and reduce the heat conduction from the accommodation cavity 50 to the inside of the shell 1; on the other hand, when the heat insulation film 41 is a soft film, it can play a filling role, that is, reduce or eliminate the gap between the outer wall of the solar photovoltaic panel 4 and the inner wall of the positioning groove 16, and further reduce heat conduction; on the other hand, when the heat insulation film 41 is a soft film, it can play a shock absorption role for the solar photovoltaic panel 4, and further reduce the risk of damage to the solar photovoltaic panel 4 under long-term vibration (since the fishing boat will continuously rise and fall with the sea surface when traveling on the sea, the fishing boat positioning device will be continuously vibrated for a long time).

[0065] As Figure 16As shown, as another embodiment, the transparent cover 5 is provided with a second ventilation hole 53. The second ventilation hole 53 penetrates through the transparent cover 5, and a second waterproof breathable valve 531 is provided in the second ventilation hole 53. The second waterproof breathable valve 531 allows air to pass through but does not allow water to pass through. The second waterproof breathable valve 531 seals the second ventilation hole 53 (that is, the second waterproof breathable valve 531 blocks the second ventilation hole 53). By providing the second waterproof breathable valve 531, the inside of the transparent cover 5 (i.e., the accommodation cavity 50) can exchange air with the external environment through the second waterproof breathable valve 531, thereby ensuring the pressure balance inside and outside the transparent cover 5, avoiding the generation of a pressure difference between the inside of the transparent cover 5 and the external environment, and moreover, the inside of the transparent cover 5 and the external environment can exchange heat through the second waterproof breathable valve 531, which is beneficial to the heat dissipation inside the transparent cover 5, and further beneficial to extending the service life of the transparent cover 5 and the solar photovoltaic panel 4 (since the transparent cover 5 and the solar photovoltaic panel 4 are exposed to light radiation for a long time, the temperature and air pressure inside the transparent cover 5 are relatively high).

[0066] Specifically, the transparent cover 5 includes a flat plate portion 51 and a side portion 52 that are integrally connected. The flat plate portion 51 is disposed opposite to the solar photovoltaic panel 4 at an interval. The side portion 52 is bent and extended from the edge of the flat plate portion 51 toward the side close to the housing 1. The side portion 52 surrounds the periphery of the solar photovoltaic panel 4, and the side portion 52 is fixedly connected to the outer wall of the housing 1. The accommodation cavity 50 is formed between the flat plate portion 51, the side portion 52, and the outer wall of the housing 1. The second ventilation hole 53 is provided on the side portion 52, thereby reducing the influence of the second waterproof breathable valve 531 on the solar photovoltaic panel 4 receiving light (since sunlight generally irradiates the solar photovoltaic panel 4 through the flat plate portion 51. If the second ventilation hole 53 is provided on the flat plate portion 51, that is, the second waterproof breathable valve 531 is provided on the flat plate portion 51, it will block the light received by the solar photovoltaic panel 4 and affect the solar power generation efficiency).

[0067] As Figures 2 to 10 shown, as an embodiment, the fishing boat positioning device further includes a heat dissipation module 6 provided in the housing 1 ( Figure 3The heat dissipation module 6 is not shown in the figure. The heat dissipation module 6 includes a fan 61. The fan 61 is disposed within the housing 1. The fan 61 can be disposed on the circuit board 21. Specifically, the fan 61 can be an axial flow fan or a centrifugal fan, etc. The circuit module 2 further includes a temperature sensor 25. The temperature sensor 25 is disposed within the housing 1. The temperature sensor 25 can be disposed on the circuit board 21. The temperature sensor 25 is used to detect the temperature within the housing 1. Both the temperature sensor 25 and the fan 61 are electrically connected to the circuit board 21, and both the temperature sensor 25 and the fan 61 are in electrical signal connection with the control module 24. The housing 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 disposed corresponding to the air outlet holes 171, and the fan 61 and the air outlet holes 171 are arranged at an interval in the up and down direction. When the fan 61 is operating, it can blow air towards the air outlet holes 171.

[0068] When the temperature sensor 25 detects that the temperature within the housing 1 reaches a first preset value (the first preset value is, for example, 45 °C), the control module 24 controls the fan 61 to start, so as to perform heat dissipation work. Specifically, after the fan 61 is started, the fan 61 discharges the high-temperature air within the housing 1 through the air outlet holes 171. At the same time, the low-temperature air outside the housing 1 is inhaled into the housing 1 through the air inlet holes 172, thereby realizing the ventilation and heat dissipation inside the housing 1 and improving the service life of the electronic components inside the housing 1. When the temperature sensor 25 detects that the temperature within the housing 1 drops to less than a set value (the set value is, for example, 40 °C), the control module 24 controls the fan 61 to turn off again. Among them, the set value is less than the first preset value.

[0069] As Figures 2 to 10 shown, as an implementation manner, the heat dissipation module 6 further includes a motor 62 and a baffle 64. Both the motor 62 and the baffle 64 are disposed within the housing 1. Specifically, the motor 62 can be disposed on the circuit board 21. The baffle 64 is disposed corresponding to the air outlet holes 171 and the air inlet holes 172. The baffle 64 is located between the air outlet holes 171 and the fan 61. The baffle 64 is in contact with the inner wall of the housing 1, and the baffle 64 can move relative to the housing 1. The motor 62 is electrically connected to the circuit board 21, and the motor 62 is in electrical signal connection with the control module 24. The motor 62 is connected to the baffle 64 through a transmission mechanism 63. The motor 62 is used to drive the baffle 64 to move (that is, the motor 62 can drive the baffle 64 to move through the transmission mechanism 63), so as to open the air outlet holes 171 and the air inlet holes 172 when performing heat dissipation work, and close (seal) the air outlet holes 171 and the air inlet holes 172 after the heat dissipation work is completed.

[0070] Specifically, in this embodiment, the transmission mechanism 63 is a gear-rack transmission mechanism. The transmission mechanism 63 includes a gear 631 and a rack 632. The gear 631 is rotatably connected to the inner wall of the housing 1, and the gear 631 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 operates, the motor 62 drives the gear 631 to rotate. When the gear 631 rotates, it drives the rack 632 to move, and then drives the baffle 64 to move (that is, the transmission mechanism 63 converts the rotational motion of the motor 62 into a linear motion). Of course, in other embodiments, the transmission mechanism 63 can also be a synchronous belt transmission mechanism, etc. At the same time, the baffle 64 can be connected to the inner wall of the housing 1 through a slide rail assembly (not shown in the figure) to limit the movement path of the baffle 64 and reduce the resistance when the baffle 64 moves. During operation, when the temperature sensor 25 detects that the temperature inside the housing 1 reaches the 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 hole 171 and the air inlet hole 172. At the same time, the control module 24 controls the fan 61 to start to perform the heat dissipation work. When the temperature sensor 25 detects that the temperature inside the housing 1 drops below 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 to drive the baffle 64 to move in the reverse direction and block the air outlet hole 171 and the air inlet hole 172, thereby preventing external moisture, dust, etc. from entering the housing 1 through the air outlet hole 171 and the air inlet hole 172.

[0071] As an implementation manner, a charging switch 28 is provided on the circuit board 21. 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 in an electrical signal manner. The charging switch 28 can specifically be an electromagnetic switch, a Mos tube switch circuit, etc.

[0072] When the temperature sensor 25 detects that the temperature inside the housing 1 reaches the second preset value (the second preset value is, for example, 55 °C), the control module 24 controls the charging switch 28 to close, so that the solar photovoltaic panel 4 is disconnected from the circuit board 21 and the battery 20, so that the solar photovoltaic panel 4 stops charging the battery 20, thereby avoiding damage to the battery 20 caused by high-temperature charging. Among them, 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 continue charging.

[0073] Such as Figures 2 to 10As shown, as an embodiment, the fishing boat positioning device also 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 through the switch assembly 26, and the disassembly detection module 7 and the switch assembly 26 are both electrically connected to the control module 24 (the disassembly detection module 7 is electrically connected to the control module 24 through the switch assembly 26 and the circuit board 21). The switch assembly 26 can specifically be an electromagnetic switch, a MOS tube switch circuit, etc. The disassembly detection module 7 is used to trigger and send an electrical signal to the control module 24 after the fishing boat positioning device is removed from the fixed component. After receiving the electrical signal, the control module 24 sends a disassembly alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the disassembly alarm message to the administrator's mobile terminal 92 (for example, the control module 24 can send information such as "the positioning terminal is suspected to be disassembled" to the mobile terminal 92 through the communication module 22 and the cloud platform 91 to remind the administrator).

[0074] The control module 24 is used to control the opening and closing of the switch assembly 26 so as to connect or disconnect the disassembly detection module 7 and the circuit board 21. The fishing boat positioning device has a working state (i.e., a normal working state) and an installation state (i.e., a debugging and installation state); 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 a forced alarm release signal; when the fishing boat positioning device is in the working state, the control module 24 controls the switch assembly 26 to be opened after receiving an alarm execution signal (the forced alarm release signal and the alarm execution signal are generally sent by the mobile terminal 92, and the mobile terminal 92 sends the above signals to the control module 24 through the cloud platform 91 and the communication module 22).

[0075] 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 parts 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.

[0076] Since the fishing boat positioning device needs to be powered on and debugged during the installation process (the fishing boat positioning device has not yet been installed on the fixed components at this time), if the disassembly alarm function is normally turned on at this time, the disassembly detection module 7 will frequently trigger the alarm (false alarm), affecting the debugging operation and interfering with the judgment of the background administrator. Therefore, the present embodiment is further provided with 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 release signal issued based on the mobile terminal 92, so that the disassembly detection module 7 is disconnected from the circuit board 21, and then the disassembly alarm function is turned off to avoid false alarms; 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 issued based on the mobile terminal 92, so that the disassembly detection module 7 is connected to 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 "turn on the disassembly alarm function" and "turn off the disassembly alarm function". When the administrator selects the option of "turn off the disassembly alarm function", a forced alarm release signal is generated; when the administrator selects the option of "turn on the disassembly alarm function", an alarm execution signal is generated).

[0077] like Figures 2 to 7 and Figure 10 As shown, 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 to the circuit board 21 through the switch assembly 26, and the light sensor 71 is electrically connected to the control module 24. A receiving hole 181 is provided on the shell wall of the shell 1, and the receiving hole 181 penetrates the shell wall of the shell 1. The receiving hole 181 is arranged corresponding to the light sensor 71, and the light guide 72 is arranged in the receiving hole 181, and the light guide 72 seals and blocks the receiving hole 181; the light guide 72 is specifically a light guide column. Among them, on the one hand, the light guide 72 plays a light guiding role, and the external light can be transmitted to the light sensor 71 through the light guide 72; on the other hand, the light guide 72 can play a role in sealing the receiving hole 181 to prevent external water vapor, dust, etc. from entering the shell 1 through the receiving hole 181.

[0078] When the fishing boat positioning device is removed from the fixing component, the light guide member 72 is exposed, enabling the light guide member 72 to conduct external light to the light sensor 71. The light sensor 71 can convert the light signal into an electrical signal after receiving the external light and send it to the control module 24, and the control module 24 then performs the disassembly alarm action. Specifically, when the fishing boat positioning device is not removed from the fixing component, the light guide member 72 is close to the fixing component, and the external light cannot irradiate the light guide member 72 under the shielding of the fixing component and thus cannot be conducted to the light sensor 71. When the fishing boat positioning device is removed from the fixing component, the light guide member 72 loses the shielding of the fixing component and is exposed. At this time, the external light will irradiate the light guide member 72, and then be conducted to the light sensor 71 to trigger the disassembly alarm.

[0079] As Figures 2 to 7 and Figure 10 shown, as an implementation manner, the disassembly detection module 7 further includes a Hall sensor 73 and a magnetic block 74. The magnetic block 74 can specifically be a magnet, a magnetic steel or other magnets. The Hall sensor 73 is arranged on the circuit board 21 and is electrically connected to the circuit board 21 through a switch component 26. The Hall sensor 73 is electrically connected to the control module 24. An accommodation groove 182 is provided on the outer wall of the housing 1. The accommodation groove 182 does not penetrate the wall of the housing 1. The accommodation groove 182 corresponds to the Hall sensor 73. The magnetic block 74 is movably arranged in the accommodation groove 182, and the magnetic block 74 is used for magnetically attracting and fixing to the fixing component (it should be noted that after the magnetic block 74 is magnetically attracted and fixed to the fixing component, a part of the magnetic block 74 is located in the accommodation groove 182).

[0080] When the fishing boat positioning device is removed from the fixing component, the magnetic block 74 disengages from the accommodation groove 182 and the distance between the magnetic block 74 and the Hall sensor 73 exceeds a preset range. The Hall sensor 73 generates an electrical signal and sends it to the control module 24. Specifically, the Hall sensor 73 is a sensor that uses a magnetic field. It controls the electronic switch of the device by detecting the change of the magnetic field intensity. It is a non-contact switch and can detect the presence of an object. The principle of the Hall sensor 73 is that it has an internal magnet and is paired with a micro electronic component. When it approaches an external magnetic field, a voltage will be generated. In this embodiment, when the fishing boat positioning device is not removed from the fixing component, the magnetic block 74 is adsorbed on the fixing 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 fixing component, since the magnetic block 74 is adsorbed on the fixing component and the fishing boat positioning device will move away from the fixing component, the magnetic block 74 and the Hall sensor 73 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.

[0081] Since the alarm of the light sensor 71 will fail when the light is dim at night (the light is weak at night, even if the fishing boat positioning device is disassembled, it will not trigger the alarm of the light sensor 71), the Hall sensor 73 alarm is set to supplement it, that is, either the light sensor 71 or the Hall sensor 73 will trigger the alarm to ensure safety.

[0082] like Figures 1 to 7 As shown, as an embodiment, the water drop detection assembly 3 and the disassembly detection module 7 are located on the same side of the housing 1, and the water drop detection assembly 3 and the solar photovoltaic panel 4 are respectively located on opposite sides of the housing 1. Specifically, the housing 1 has a mounting surface 100, the mounting hole 11, the first air vent 14, the receiving hole 181 and the receiving groove 182 are all arranged on the shell wall where the mounting surface 100 of the housing 1 is located, and the positioning groove 16 is arranged on the outer wall of the housing 1 away from the mounting surface 100. During installation, the mounting surface 100 is vertically downward or tilted downward, and the angle between the mounting surface 100 and the horizontal direction can be 0°~60°.

[0083] The fishing boat positioning device also includes a mounting assembly 8, which is arranged on opposite sides outside the shell 1; the mounting assembly 8 includes a mounting plate 81, which is attached to the mounting surface 100 and fixedly connected to the shell 1, and the mounting plate 81 protrudes from the mounting surface 100, and is used to be fixedly connected to the fixing component.

[0084] Specifically, the mounting assembly 8 further includes a first fixing member 82, a buffer pad 83 and a second fixing member 84. The mounting plate 81 is fixedly connected to the housing 1 through the first fixing member 82, and the mounting plate 81 is fixedly connected to the fixing member 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.

[0085] like Figures 1 to 7 As shown, as an implementation mode, the receiving hole 181 is arranged corresponding to the mounting plate 81, the mounting plate 81 covers the receiving hole 181, and a light-through hole 811 is arranged at a position corresponding to the receiving hole 181 on the mounting plate 81; such an arrangement enables the mounting plate 81 to block lateral light, and reduces the external light from irradiating the light guide 72 laterally through the gap between the mounting surface 100 and the fixing component, causing false alarms. The receiving groove 182 is staggered with the mounting plate 81, that is, the mounting plate 81 does not cover the receiving groove 182.

[0086] The light-transmitting hole 811 and the receiving hole 181 are both circular holes. The diameter of the light-transmitting hole 811 is larger than that of the receiving hole 181. A circular light-shielding ring 75 is provided in the light-transmitting hole 811. The light-shielding ring 75 is fixed to the inner wall of the light-transmitting hole 811 (specifically, it can be fixed by adhesive bonding), and the inner diameter of the light-shielding ring 75 is larger than or equal to the diameter of the receiving hole 181. The light-shielding ring 75 can specifically be a black rubber ring, which can absorb lateral light. By providing the light-shielding ring 75, the light-shielding ring 75 can further block lateral light (there may be a gap between the mounting plate 81 and the fixing component, and external light may laterally irradiate the light guide member 72 through the gap between the two, resulting in false alarms); and since the inner diameter of the light-shielding ring 75 is larger than or equal to the diameter of the receiving hole 181, when the fishing boat positioning device is disassembled, the light-shielding ring 75 will not block the external light from irradiating the light guide member 72.

[0087] As Figure 14 shown, as another implementation manner, a magnetic light-shielding member 76 is movably arranged in the light-transmitting hole 811. The magnetic light-shielding member 76 is a circular block structure. The outer diameter of the magnetic light-shielding member 76 is larger than or equal to the diameter of the receiving hole 181. The magnetic light-shielding member 76 can specifically be a magnet, a magnetic steel or other magnetic bodies. The magnetic light-shielding member 76 is used for magnetic adsorption and fixation to the fixing component; when the fishing boat positioning device is removed from the fixing component, the magnetic light-shielding member 76 disengages from the light-transmitting hole 811. Specifically, when the fishing boat positioning device is not disassembled, the magnetic light-shielding member 76 is located in the light-transmitting hole 811, and the magnetic light-shielding member 76 can block external light to avoid false alarms; when the fishing boat positioning device is removed from the fixing component, since the magnetic light-shielding member 76 is magnetically adsorbed and fixed to the fixing component, at this time the magnetic light-shielding member 76 disengages from the light-transmitting hole 811, and external light can irradiate the light guide member 72 through the light-transmitting hole 811.

[0088] As an implementation manner, the circuit module 2 further includes an acceleration sensor 27 arranged in the housing 1. The acceleration sensor 27 can specifically be arranged on the circuit board 21. The acceleration sensor 27 is electrically connected to the circuit board 21 through a switch assembly 26. The acceleration sensor 27 is electrically connected to the control module 24 in an electrical signal manner. The acceleration sensor 27 is used for detecting the acceleration signal of the fishing boat positioning device; when the acceleration signal value detected by the acceleration sensor 27 exceeds a preset value, the control module 24 sends a capsizing alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the capsizing alarm message to the mobile terminal 92 of the administrator to implement the capsizing alarm function.

[0089] Specifically, the acceleration sensor 27 (i.e., G-sensor) is a sensor that estimates the speed and displacement of an object by measuring its acceleration. The acceleration sensor 27 can detect changes in the acceleration force of an object (the acceleration force is the force acting on an object during acceleration, such as various movement changes like shaking, falling, rising, and descending can be converted into electrical signals by the G-sensor), and measure the acceleration and tilt angle of the object. The control module 24 determines whether the fishing boat has capsized or overturned by judging whether the acceleration signal value detected by the acceleration sensor 27 exceeds a preset value. In this embodiment, the acceleration sensor 27 is a six-axis sensor. When the accelerations detected by the acceleration sensor 27 in the XYZ directions all exceed the threshold value, the control module 24 determines that the fishing boat has capsized or overturned.

[0090] At the same time, since the acceleration sensor 27 is electrically connected to the circuit board 21 through the switch assembly 26, when the fishing boat positioning device is in the installed state, the capsizing alarm function can be turned off to avoid false alarms; when the fishing boat positioning device is in the working state, the capsizing alarm function can be normally turned on (the opening and closing control principle of the capsizing alarm function is similar to that of the disassembly alarm function and will not be elaborated here).

[0091] As an implementation manner, the housing 1 includes a main housing 1A and a bottom cover 1B that are connected to each other. The solar photovoltaic panel 4 is disposed on the outer wall of the main housing 1A. The mounting holes 11, the first ventilation holes 14, the receiving holes 181, the receiving grooves 182, etc. are all disposed on the bottom cover 1B.

[0092] As an implementation manner, the communication module 22 is a 2G / 4G dual-band network communication module, that is, the communication module 22 can be compatible with the communication of the 2G network and the 4G network. The positioning module 23 is a GPS / BD dual-positioning module, that is, the positioning module 23 is compatible with GPS positioning and Beidou positioning. The control module 24 is an MCU (micro control unit).

[0093] The advantages of the fishing boat positioning device provided by the embodiment of the present invention include:

[0094] 1. By setting the water entry detection component 3, when the fishing boat positioning device falls into the water, the water outside the housing 1 can enter the mounting hole 11 to make the water entry detection component 3 conductive. Then, the control module 24 sends a water entry alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 sends the water entry alarm message to the administrator's mobile terminal 92, so that the administrator can timely know that the fishing boat has capsized and fallen into the water, realizing the water entry alarm function of the fishing boat positioning device and improving the safety of the fishing boat.

[0095] 2. By arranging a transparent cover 5 on the outer wall of the housing 1, the transparent cover 5 covers the solar photovoltaic panel 4, thereby protecting the solar photovoltaic panel 4, preventing the solar photovoltaic panel 4 from being corroded by the humid seawater environment, and extending the service life of the solar photovoltaic panel 4. At the same time, by opening a first air hole 14 on the housing 1, and arranging a first waterproof air-permeable valve 141 in the first air hole 14, the interior of the housing 1 can be ventilated with the external environment through the first waterproof air-permeable valve 141, thereby ensuring the pressure balance between the inside and outside of the housing 1, avoiding the pressure difference between the inside of the housing 1 and the external environment, thereby extending the life of the housing 1 and the electronic components inside the housing 1; at the same time, the inside of the housing 1 and the external environment can exchange heat through the first waterproof air-permeable valve 141, which is beneficial to the heat dissipation inside the housing 1, and further beneficial to extending the life of the electronic components inside the housing 1.

[0096] 3. By arranging a second waterproof breathable valve 531 on the transparent cover 5, the interior of the transparent cover 5 can be ventilated with the external environment through the second waterproof breathable valve 531, thereby ensuring the pressure balance between the inside and outside of the transparent cover 5, avoiding the pressure difference between the inside of the transparent cover 5 and the external environment, and the inside of the transparent cover 5 and the external environment can exchange heat through the second waterproof breathable valve 531, which is beneficial to the heat dissipation inside the transparent cover 5, and further beneficial to extending the life of the transparent cover 5 and the solar photovoltaic panel 4.

[0097] 4. By providing the heat dissipation module 6 , the heat dissipation module 6 can dissipate heat when the temperature inside the housing 1 is high, thereby increasing the life of the electronic components inside the housing 1 .

[0098] 5. By setting up a disassembly detection module 7, when the fishing boat positioning device is removed from the fixed parts of the fishing boat, the disassembly detection module 7 is triggered, and then the control module 24 sends a disassembly alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the disassembly alarm message to the administrator's mobile terminal 92, so that the administrator can know 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.

[0099] 6. By setting the 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 release signal issued based on the mobile terminal 92, so that the disassembly detection module 7 is disconnected from the circuit board 21, and then the disassembly alarm function is turned off to avoid false alarms; 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 issued based on the mobile terminal 92, so that the disassembly detection module 7 is connected to the circuit board 21, and then the normal disassembly alarm function is restored.

[0100] 7. By setting the acceleration sensor 27, when the acceleration sensor 27 detects that the acceleration signal value of the fishing boat positioning device exceeds the preset value, the control module 24 sends a capsizing alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the capsizing alarm message to the mobile terminal 92 of the administrator, realizing the capsizing alarm function.

[0101] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
