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 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. In some usage scenarios, there is a risk that the fishing boat positioning device may be removed privately (for example, when a fishing boat is docked at a port and is stolen, the fishing boat positioning device will be removed from the fishing boat), making it impossible for the administrator to track the location of the fishing boat; however, the commonly used fishing boat positioning devices generally do not have a disassembly alarm function. When the fishing boat positioning device is privately disassembled, the fishing boat positioning device cannot issue an alarm in time, affecting the safety of the fishing boat. Summary of the invention

[0007] In an achievable manner, the disassembly detection module further includes a Hall sensor and a magnetic block; the Hall sensor is disposed on the circuit board and electrically connected to the circuit board through the switch assembly, and the Hall sensor is electrically connected to the control module; an accommodating groove is disposed on the outer wall of the housing, the accommodating groove is disposed corresponding to the Hall sensor, the magnetic block is movably disposed in the accommodating groove, and the magnetic block is used to be fixed to the fixing component by magnetic attraction; When the fishing boat positioning device is removed from the fixing component, the distance between the magnetic block and the Hall sensor exceeds a preset range, and the Hall sensor generates an electrical signal and sends it to the control module.

[0008] In one feasible manner, the shell has a mounting surface, and the accommodating hole and the accommodating groove are both arranged on the shell wall where the mounting surface of the shell is located; the fishing boat positioning device also includes a fixing component, and the fixing component includes a mounting plate; the mounting plate is attached to the mounting surface and fixedly connected to the shell, and the mounting plate is used to be fixedly connected to the fixing component.

[0009] In one achievable manner, the accommodating hole is arranged corresponding to the mounting plate, the mounting plate covers the accommodating hole, and a light-through hole is arranged at a position on the mounting plate corresponding to the accommodating hole; the accommodating groove is staggered with the mounting plate.

[0010] In one feasible manner, the light-through hole and the receiving hole are both circular holes, the diameter of the light-through hole is larger than the diameter of the receiving hole, a circular light-shielding ring is provided in the light-through hole, the light-shielding ring is fixed to the inner wall of the light-through hole, and the inner diameter of the light-shielding ring is larger than or equal to the diameter of the receiving hole.

[0011] In one feasible manner, a magnetic light shielding piece is movably provided in the light-through hole, and the magnetic light shielding piece is used to be magnetically fixed to the fixed component; when the fishing boat positioning device is removed from the fixed component, the magnetic light shielding piece falls out of the light-through hole.

[0033] The specific implementation of the present invention is further described in detail below in conjunction with 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.

[0034] 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 sequence or order.

[0035] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the present invention are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed in the present invention.

[0036] like Figures 1 to 10As shown, an embodiment of the present invention provides a fishing boat positioning device, which is used to be installed on a fixed component (not shown) of a fishing boat, and the fixed component can be a structural component such as a deck and a mast of the fishing boat. The fishing boat positioning device includes a housing 1, a circuit module 2 and a water drop detection component 3. The housing 1 is a sealed structure, and the circuit module 2 is arranged in 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 drop detection component 3 is electrically connected to the circuit board 21. The water drop detection component 3, the communication module 22 and the positioning module 23 are all electrically connected to the control module 24 (specifically, the water drop 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). 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., the cloud server) through the communication module 22. The mobile terminal 92 (such as a mobile phone, computer, etc.) of the fishing boat manager can interact with the cloud platform 91 for data, thereby obtaining the 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).

[0037] The shell wall of the housing 1 is provided with a mounting hole 11, which is communicated with the inner cavity of the housing 1 and the outside of the housing 1 at the same time. The water drop detection component 3 is at least partially arranged in the mounting hole 11 and blocks the mounting hole 11, thereby preventing external water, dust, etc. from entering the housing 1 through the mounting hole 11. Among them, since the mounting hole 11 is communicated with the inner cavity of the housing 1, it is convenient to electrically connect the water drop detection component 3 with the circuit board 21; since the mounting hole 11 is communicated with the outside of the housing 1, external water can enter the mounting hole 11.

[0038] When the fishing boat positioning device falls into the water, the water outside the shell 1 can enter the installation hole 11 to turn on the water detection component 3, and the control module 24 sends a water fall alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the water fall alarm message to the administrator's mobile terminal 92 (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, the water fall 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 fall alarm message to the cloud platform 91 through the communication module 22; when the fishing boat positioning device falls into the water, the external water will enter the installation hole 11, and the water fall detection component 3 will be turned on and generate an electrical signal after contacting the water. The water fall detection component 3 transmits the electrical signal to the control module 24, and the control module 24 sends a water fall alarm message to the cloud platform 91 through the communication module 22 after receiving the electrical signal.

[0039] The fishing boat positioning device provided in this embodiment is provided with a water-falling 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 water-falling detection component 3 conductive, and then the control module 24 sends a water-falling alarm information to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the water-falling 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 water-falling alarm function of the fishing boat positioning device and improving the safety of the fishing boat.

[0040] like Figure 2 , Figure 5 and Figure 6As shown in the figure, as an embodiment, the outer end of the water drop detection component 3 (i.e., the end of the water drop detection component 3 close to the outer side of the housing 1) is spaced from the outer surface of the housing 1, i.e., the lower end of the water drop detection component 3 is located above the lower surface of the housing 1. In other words, the water drop detection component 3 is completely located in the mounting hole 11. Such a configuration can reduce the risk of misjudgment caused by the water drop detection component 3 being turned on after contacting the water on the surface of the housing 1 under non-water drop conditions and when there is water on the surface of the housing 1 (e.g., in rainy weather) (if the outer end of the water drop detection component 3 is exposed to the outside of the mounting hole 11 or the outer end of the water drop 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 drop detection component 3; and because the outer end of the water drop detection component 3 is spaced from the outer surface of the housing 1, i.e., there is a height difference between the outer end of the water drop 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 drop detection component 3, thereby reducing the risk of misjudgment). As an implementation manner, 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.

[0041] like Figures 2 to 6 and Fig.10 As shown, as an embodiment, the water-falling detection assembly 3 includes a first conductive member 31 and a second conductive member 32, and the first conductive member 31 and the second conductive member 32 are both electrically connected to the control module 24. The mounting hole 11 includes a first sub-hole 111 and a second sub-hole 112 arranged at intervals, the first conductive member 31 is arranged in the first sub-hole 111 and blocks the first sub-hole 111, and the second conductive member 32 is arranged in the second sub-hole 112 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, so that the first conductive member 31 and the second conductive member 32 are connected through water.

[0042] Specifically, in the present embodiment, the water-fall 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 the current detection circuit 33 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 connected by water, a current circuit is formed between the first conductive member 31, the second conductive member 32 and the current detection circuit 33, and 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-fall alarm message to the cloud platform 91 through the communication module 22. The current detection circuit 33 may specifically include a resistor, a first conductive member 31, a resistor, and a second conductive member 32 are arranged in series, and 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 turned on, 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 fall 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 sensing switch, an electromagnetic switch, a MOS tube switch circuit, etc.). In other embodiments, the water fall detection component 3 may also adopt other structures.

[0043] 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 provided on the side of the partition 12 close to the outside of the shell 1, and 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 connected through the groove 121; the outer end of the first conductive member 31 (i.e., the end of the first conductive member 31 close to the outside of the shell 1) and the outer end of the second conductive member 32 (i.e., the end of the second conductive member 32 close to the outside of the shell 1) are both located on the side of 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 member 31 and the lower end of the second conductive member 32 are both located above the groove 121. Among them, by setting the outer end of the first conductive member 31 and the outer end of the second conductive member 32 at a distance 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 a small amount of water exists 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 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 member 31 and the second conductive member 32 is shortened, and the creepage distance between the two is reduced. At the same time, by arranging 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 turned on after the fishing boat positioning device falls into the water, and the sensitivity of the water fall detection is improved (even in the river water with low conductivity, the first conductive member 31 and the second conductive member 32 can be turned on. According to experiments, 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 turned on in the sea water with high conductivity, but cannot be turned on or are insensitive in the river water with low conductivity), but the risk of misjudgment of the first conductive member 31 and the second conductive member 32 in rainy weather due to the close creepage distance can be reduced. As an implementation manner, the depth of the groove 121 may be 1 mm to 4 mm, or 2 mm to 3 mm.

[0044] like 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 snap connection, interference fit, 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 snap connection, interference fit, 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.

[0045] The shortest distance L between the first sub-hole 111 and the second sub-hole 112 satisfies the following conditions: L=k*D; wherein D is the outer diameter of the first conductive member 31 (the second conductive member 32), k is the conductive safety factor, and the value range of k is 0.2~0.8. 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, 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 (i.e., the contact areas between water and the first conductive member 31 and the second conductive member 32 are larger), that is, the first conductive member 31 and the second conductive member 32 are more easily conductive, and at this time, the distance between the first sub-hole 111 and the second sub-hole 112 can be set to be 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 to be 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.

[0046] 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 penetrate 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 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, and 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.

[0047] like Figures 2 to 6 As shown, as an embodiment, the mounting hole 11 passes through the shell wall of the shell 1, and the opposite ends of the mounting hole 11 are directly connected to the inner cavity of the shell 1 and the outside of the shell 1 respectively. That is, the first sub-hole 111 and the second sub-hole 112 both pass through the shell wall of the shell 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 shell 1 and the outside of the shell 1 respectively.

[0048] like Fig.12 and Fig.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 shell 1, and the mounting hole 11 does not pass through the outer surface of the shell 1; the shell wall of the shell 1 is also provided with a conducting hole 13, one end of the conducting hole 13 is connected to the side of the mounting hole 11 close to the outside of the shell 1, and the other end of the conducting hole 13 is connected to the outside of the shell 1; the aperture of the conducting hole 13 is smaller than the aperture of the mounting hole 11. There are multiple conducting holes 13, and the multiple conducting holes 13 are arranged at intervals on 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, and the first sub-hole 111 and the second sub-hole 112 both penetrate the inner surface of the shell 1, and the first sub-hole 111 and the second sub-hole 112 do not penetrate the outer surface of the shell 1, and the first sub-hole 111 and the second sub-hole 112 are connected through the groove 121; the number of the through holes 13 is two, one end of one of the through holes 13 is connected to the side of the first sub-hole 111 close to the outside of the shell 1, and the other end is connected to the outside of the shell 1, and one end of the other through hole 13 is connected to the side of the second sub-hole 112 close to the outside of the shell 1, and the other end is connected to the outside of the shell 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, the 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.

[0049] like Fig.12 As shown in FIG. 1 , as an embodiment, the conducting hole 13 is an inclined hole, that is, the conducting hole 13 is inclined, 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°. Fig.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 a 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, which can reduce the probability of rainwater directly entering the mounting hole 11 in rainy weather, thereby reducing the risk of misjudgment (when the fishing boat positioning device falls into the water, the fishing boat positioning device will be immersed in the water, so it will not affect the entry of water).

[0050] like Figures 2 to 6 As shown, as an embodiment, a spring ejector pin 211 is provided on the circuit board 21, and the spring ejector pin 211 is electrically connected to the circuit board 21; the spring ejector pin 211 is provided corresponding to the water drop detection component 3, and the spring ejector pin 211 is in contact with the water drop detection component 3 and is electrically connected, that is, the water drop detection component 3 is electrically connected to the circuit board 21 through the spring ejector pin 211. Specifically, there are two spring ejector pins 211, and the two spring ejector pins 211 are in contact with the top of the first conductive member 31 and the top of the second conductive member 32 and are electrically connected.

[0051] like Fig.11 As shown, as another embodiment, a floating bar 10 is provided on the outer peripheral wall of the shell 1, and the density of the floating bar 10 is less than that of the shell 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 bar 10. By providing the floating bar 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 with the fishing boat. For example, during the installation process of the fishing boat positioning device, or in windy and choppy 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 bar 10, and the fishing boat positioning device can still work normally at this time, avoiding the fishing boat positioning device from sinking directly to the bottom of the water, and the subsequent staff can salvage the fishing boat positioning device onto the ship and continue to use it (it should be noted that since the fishing boat positioning device will first be immersed in the water and then float to the surface when it falls into the water from a certain height, it will also trigger the falling water alarm). The material of the floating bar 10 can be polyurethane foam, epoxy foam plastic, etc., and the floating bar 10 can be a solid structure or a hollow structure. As an embodiment, the shell 1 is a rectangular parallelepiped structure, and the floating strip 10 can be arranged on the outer walls of the shell 1 on opposite sides, or on the outer walls of the four sides, etc. Of course, the shell 1 can also be other shapes, and the setting position of the floating strip 10 can be adaptively adjusted according to the shape of the shell 1.

[0052] like Figures 1 to 8 As shown, as an embodiment, the fishing boat positioning device also includes a battery 20, a solar photovoltaic panel 4 and a transparent cover 5. The battery 20 is arranged in the housing 1. The battery 20 and the solar photovoltaic panel 4 are both electrically connected to the 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 through the circuit board 21, and the solar photovoltaic panel 4 is used to charge the battery 20. The transparent cover 5 can be made of transparent plastic, transparent glass and other materials.

[0053] The transparent cover 5 is fixedly connected to the outer wall of the shell 1 (specifically, it can be connected by means of adhesive bonding, screw locking, etc.), and a receiving chamber 50 is formed between the transparent cover 5 and the outer wall of the shell 1. The receiving chamber 50 is a sealed chamber, and the receiving chamber 50 is isolated from the inner cavity of the shell 1, that is, the receiving chamber 50 and the inner cavity of the shell 1 are not connected to each other, thereby reducing the heat in the receiving chamber 50 from being transferred to the shell 1 (the transparent cover 5 will be exposed to light for a long time, so the temperature in the receiving chamber 50 is relatively high, and the temperature in the receiving chamber 50 is generally higher than the temperature in the shell 1). The solar photovoltaic panel 4 is arranged in the receiving chamber 50, and the solar photovoltaic panel 4 is fixed on the outer wall of the shell 1 (specifically, it can be fixed by means of screw locking, etc.), that is, the transparent cover 5 seals and covers the solar photovoltaic panel 4; because the transparent cover 5 is a transparent structure, it does not affect the external light from irradiating the solar photovoltaic panel 4. A first air vent 14 is provided on the shell wall of the shell 1. The first air vent 14 runs through the shell wall of the shell 1. A first waterproof air permeable valve 141 is provided in the first air vent 14. The first waterproof air permeable valve 141 allows air to pass through but does not allow water to pass through. The first waterproof air permeable valve 141 seals the first air vent 14 (that is, the first waterproof air permeable valve 141 blocks the first air vent 14).

[0054] The fishing boat positioning device provided in this embodiment is provided with a transparent cover 5 on the outer wall of the housing 1, and 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 providing a first vent hole 14 on the housing 1, and providing a first waterproof vent valve 141 in the first vent hole 14, the interior of the housing 1 can be ventilated (i.e., gas exchange) with the external environment through the first waterproof vent 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 (i.e., heat exchange) with the external environment through the first waterproof vent valve 141, thereby facilitating the heat dissipation inside the housing 1 (because the fishing boat positioning device is exposed to light radiation for a long time and the electronic components inside the housing 1 generate heat when working, the temperature inside the housing 1 is generally higher than the temperature of the external environment), thereby facilitating the extension of the life of the electronic components inside the housing 1.

[0055] like Figures 1 to 7As shown, as an embodiment, a wire hole 15 is provided on the shell wall of the shell 1, and the wire hole 15 penetrates the shell wall of the shell 1. The wire hole 15 is arranged corresponding to the accommodating cavity 50. The solar photovoltaic panel 4 and the circuit board 21 are electrically connected through a cable (not shown in the figure), and 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 being connected to 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 to the shell 1 through the wire hole 15.

[0056] 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-passing hole 15 is provided corresponding to the positioning groove 16, that is, the wire-passing hole 15 is connected with the positioning groove 16; the solar photovoltaic panel 4 is provided in the positioning groove 16, the size of the positioning groove 16 is adapted to the size of the solar photovoltaic panel 4, and the outer wall of the solar photovoltaic panel 4 is closely fitted with the inner wall of the positioning groove 16, thereby reducing or avoiding the heat in the accommodating 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, the solar photovoltaic panel 4 and the positioning groove 16 are both rectangular parallelepiped structures, that is, the solar photovoltaic panel 4 is a block-shaped structure, the positioning groove 16 is a square groove, and 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.

[0057] like Fig.15 Shown and combined Figure 3 As another embodiment, a heat-insulating film 41 is provided on the inner wall of the positioning groove 16, and the heat-insulating film 41 is sandwiched between the inner wall of the positioning groove 16 and the solar photovoltaic panel 4, and the two sides of the heat-insulating film 41 are respectively in contact with the inner wall of the positioning groove 16 and the solar photovoltaic panel 4. A hole needs to be opened on the heat-insulating film 41 at a position corresponding to the wire hole 15 to facilitate wiring. The heat-insulating film 41 can be specifically 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 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 vibrated for a long time).

[0058] like Fig.16As shown, as another embodiment, the transparent cover 5 is provided with a second air hole 53, the second air hole 53 penetrates the transparent cover 5, and a second waterproof air valve 531 is provided in the second air hole 53, the second waterproof air valve 531 allows air to pass through but does not allow water to pass through, and the second waterproof air valve 531 seals the second air hole 53 (i.e., the second waterproof air valve 531 blocks the second air hole 53). By providing the second waterproof air valve 531, the inside of the transparent cover 5 (i.e., the accommodating chamber 50) can be ventilated with the external environment through the second waterproof air 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 air valve 531, which is beneficial to the heat dissipation inside the transparent cover 5, and further beneficial to prolonging the life of the transparent cover 5 and the solar photovoltaic panel 4 (because 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).

[0059] Specifically, the transparent cover 5 includes a flat plate portion 51 and a side portion 52 connected in an integral manner. The flat plate portion 51 is arranged opposite to the solar photovoltaic panel 4 at an interval. The side portion 52 is formed by bending and extending the edge of the flat plate portion 51 toward a side close to the shell 1. The side portion 52 is arranged around the periphery of the solar photovoltaic panel 4. The side portion 52 is fixedly connected to the outer wall of the shell 1. The accommodating cavity 50 is formed between the flat plate portion 51, the side portion 52 and the outer wall of the shell 1. The second air vent 53 is arranged on the side portion 52, thereby reducing the influence of the second waterproof air vent 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 air vent 53 is arranged on the flat plate portion 51, that is, the second waterproof air vent 531 is arranged 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).

[0060] like Figures 2 to 10 As shown, as an embodiment, the fishing boat positioning device also includes a heat dissipation module 6 ( Figure 3The heat dissipation module 6 is not shown in the figure), and 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 be an axial flow 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 an air outlet 171 and an air inlet 172 at intervals. The air outlet 171 and the air inlet 172 are arranged close to each other. The fan 61 is arranged corresponding to the air outlet 171, and the fan 61 and the air outlet 171 are arranged at intervals up and down. The fan 61 can blow air to the air outlet 171 when it is running.

[0061] When the temperature sensor 25 detects that the temperature inside 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 turn on to perform heat dissipation. Specifically, when the fan 61 is turned on, the fan 61 discharges the high-temperature air inside the housing 1 through the air outlet 171, and at the same time, the low-temperature air outside the housing 1 is sucked into the housing 1 through the air inlet 172, thereby achieving ventilation and heat dissipation inside the housing 1 and improving the life of the electronic components inside the housing 1; when the temperature sensor 25 detects that the temperature inside 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. Among them, the set value is less than the first preset value.

[0062] like Figures 2 to 10 As shown, as an embodiment, the heat dissipation module 6 further includes a motor 62 and a baffle 64, both of which are arranged in the housing 1, and the motor 62 can be specifically arranged on the circuit board 21. The baffle 64 is arranged corresponding to the air outlet 171 and the air inlet 172, and the baffle 64 is located between the air outlet 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 electrically connected to the control module 24; the motor 62 is connected to the baffle 64 through the transmission mechanism 63, and 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 171 and the air inlet 172 when performing the heat dissipation work, and close (seal) the air outlet 171 and the air inlet 172 after the heat dissipation work is completed.

[0063] Specifically, in this embodiment, the transmission mechanism 63 is a gear rack transmission mechanism, and 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 is meshed 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, and the gear 631 drives the rack 632 to move when rotating, thereby driving the baffle 64 to move (that is, 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. 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) to limit the moving path of the baffle 64 and reduce the resistance of the baffle 64 when it moves. 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, and at the same time, the control module 24 controls the fan 61 to turn on to perform heat dissipation; 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 cover the air outlet 171 and the air inlet 172, thereby preventing external water vapor, dust, etc. from entering the shell 1 through the air outlet 171 and the air inlet 172.

[0064] As an implementation, 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 an electromagnetic switch, a MOS tube switch circuit, etc.

[0065] When the temperature sensor 25 detects that the temperature inside the housing 1 reaches a 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; wherein 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 to less than the second preset value, the control module 24 controls the charging switch 28 to open to continue charging.

[0066] like 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).

[0067] 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).

[0068] 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.

[0069] 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).

[0070] like Figures 2 to 7 and Fig.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.

[0071] When the fishing boat positioning device is removed from the fixed component, the light guide 72 is exposed, so that the light guide 72 can transmit the external light to the optical sensor 71. After receiving the external light, the optical sensor 71 can convert the optical signal into an electrical signal and send it to the control module 24, and the control module 24 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, and the external light cannot be irradiated to the light guide 72 under the shielding of the fixed component, and it cannot be transmitted to the optical sensor 71; when the fishing boat positioning device is removed from the fixed component, the light guide 72 loses the shielding 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 optical sensor 71 and trigger the disassembly alarm.

[0072] like Figures 2 to 7 and Fig.10 As shown, as an embodiment, the disassembly detection module 7 also includes a Hall sensor 73 and a magnetic block 74. The magnetic block 74 can be a magnet, magnetic steel or other magnetic body; the Hall sensor 73 is arranged on the circuit board 21 and is electrically connected to the circuit board 21 through the switch assembly 26, and the Hall sensor 73 is electrically connected to the control module 24. A receiving groove 182 is arranged on the outer wall of the housing 1, and the receiving groove 182 does not penetrate the shell wall of the housing 1. The receiving groove 182 is arranged corresponding to the Hall sensor 73, and the magnetic block 74 is movably arranged in the receiving groove 182. The magnetic block 74 is used to be fixed to the fixed component by magnetic attraction (it should be noted that when the magnetic block 74 is fixed to the fixed component by magnetic attraction, a part of the magnetic block 74 is located in the receiving groove 182).

[0073] When the fishing boat positioning device is removed from the fixed component, the magnetic block 74 escapes from the receiving groove 182 and the distance between the magnetic block 74 and the Hall sensor 73 exceeds the preset range, and 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 the 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 will generate 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 be away from the fixed component, causing the magnetic block 74 and the Hall sensor 73 to be 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 a disassembly alarm.

[0074] 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.

[0075] 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°.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] Both the light-through hole 811 and the receiving hole 181 are circular holes. The diameter of the light-through hole 811 is larger than the diameter of the receiving hole 181. A circular light-shielding ring 75 is provided in the light-through hole 811. The light-shielding ring 75 is fixed to the inner wall of the light-through hole 811 (specifically, it 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 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 fixed component, and external light may pass through the gap between the two and irradiate the light guide 72 laterally, causing a false alarm); and because the inner diameter of the light-shielding ring 75 is greater 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 external light from irradiating the light guide 72.

[0080] like Fig.14 As shown, as another embodiment, a magnetic light shielding member 76 is movably arranged in the light hole 811. The magnetic light shielding member 76 is a circular block structure. The outer diameter of the magnetic light shielding member 76 is greater than or equal to the diameter of the accommodating hole 181. The magnetic light shielding member 76 can be a magnet, a magnetic steel or other magnet. The magnetic light shielding member 76 is used to be fixed to the fixed component by magnetic attraction. When the fishing boat positioning device is removed from the fixed component, the magnetic light shielding member 76 is removed from the light hole 811. Specifically, when the fishing boat positioning device is not removed, the magnetic light shielding member 76 is located in the light 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 fixed component, since the magnetic light shielding member 76 is fixed to the fixed component by magnetic attraction, the magnetic light shielding member 76 is removed from the light hole 811 at this time, and external light can pass through the light hole 811 to irradiate the light guide 72.

[0081] As an embodiment, the circuit module 2 also includes an acceleration sensor 27 arranged in the shell 1. The acceleration sensor 27 can be specifically 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. 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 the preset value, the control module 24 sends a capsize alarm information to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the capsize alarm information to the administrator's mobile terminal 92 to realize the capsize alarm function.

[0082] Specifically, the acceleration sensor 27 (also known as the 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 the object (the acceleration force is the force acting on the object during the acceleration process, such as shaking, falling, rising, falling and other various movement changes 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 tipped over or capsized by judging 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. When the acceleration sensor 27 detects that the acceleration in the XYZ directions exceeds the threshold, the control module 24 determines that the fishing boat has tipped over or capsized.

[0083] 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 installation 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 turned on normally (the opening and closing control principle of the capsizing alarm function is similar to the opening and closing control principle of the disassembly alarm function, which will not be repeated here).

[0084] As an embodiment, the shell 1 includes a main shell 1A and a bottom cover 1B connected to each other, the solar photovoltaic panel 4 is arranged on the outer wall of the main shell 1A, and the mounting hole 11, the first air vent 14, the accommodating hole 181 and the accommodating groove 182 are all arranged on the bottom cover 1B.

[0085] As an implementation method, the communication module 22 is a 2G / 4G dual-frequency network communication module, that is, the communication module 22 is 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).

[0086] The advantages of the fishing boat positioning device provided by the embodiment of the present invention include: 1. By setting up the water-falling detection component 3, when the fishing boat positioning device falls into the water, the water outside the shell 1 can enter the installation hole 11 to make the water-falling detection component 3 conductive, and then the control module 24 sends a water-falling alarm information to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the water-falling 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, realize the water-falling alarm function of the fishing boat positioning device, and improve the safety of the fishing boat.

[0087] 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.

[0088] 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.

[0089] 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 .

[0090] 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.

[0091] 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.

[0092] 7. By setting up 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 capsize alarm message to the cloud platform 91 through the communication module 22, and the cloud platform 91 then sends the capsize alarm message to the administrator's mobile terminal 92 to realize the capsize alarm function.

[0093] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
