Description

Technical Field

[0001] The utility model relates to the technical field of fishery rescue, in particular to a shipborne safety positioning device. Background Art

[0002] my country has a long coastal line and a special geographical location. Small ships are widely used by boat people due to their low cost and convenient movement. However, in the application of small ships, it is impossible to directly use the safety positioning device used by motor vehicles for timely warning. The reason is that the operating environment of fishing boats is on the sea. The safety positioning device used by the vehicle is not waterproof and requires a continuous power supply device to power it. The "Photovoltaic Black Box" with the publication number CN204066213U provides a safety positioning device for small ships, which uses a water drop sensor as a water drop detection. When the photovoltaic black box encounters liquid infiltration, the water drop sensor will also generate an alarm signal, which is very likely to cause false alarms. Summary of the Invention

[0047] See also Figures 1 to 4 The present embodiment provides a shipborne safety positioning device, comprising a base 1, a control unit 2, a first partition 3, a cover 4, a first light-emitting diode group, and a first photoresistor group. The base 1 has a first chamber and a first opening, and the first opening is arranged above the first chamber; the control unit 2 is arranged in the first chamber; the first partition 3 is arranged in the first chamber, and the first partition 3 is arranged at the first opening. The first partition 3 has a first upper surface and a first lower surface; the cover 4 covers the first opening, and the cover 4 has a second chamber and a second opening, and the second opening is arranged below the second chamber. The first opening coincides with the second opening. The cover 4 has a curved surface structure, and the second chamber is arranged on the concave side of the curved surface structure. The cover 4 is made of a transparent material. The cover plate 4 is made of a material; a first light-emitting diode group is arranged on the first upper surface, the first light-emitting diode group includes at least one first light-emitting diode 31, the first light-emitting diode group is electrically connected to the control unit 2, and the first light-emitting diode group emits a first detection light beam a according to a first preset frequency, the first detection light beam a is reflected by the concave side of the cover plate 4 to form a first reflected light beam b, and the first detection light beam a is transmitted through the cover plate 4 to form a first transmitted light beam c; a first photoresistor group is arranged on the first upper surface and is arranged opposite to the first light-emitting diode group, the first photoresistor group includes at least one first photoresistor 32, the first photoresistor group is electrically connected to the control unit 2, and the first photoresistor 32 is used to absorb the light intensity of the first reflected light beam b.

[0048] In this embodiment, the base 1 has a first chamber. Optionally, the base 1 may be Figure 1 As shown, a first opening is provided above the base 1, and the first chamber is used to accommodate the control unit 2. The first partition 3 can be made of a heat dissipation material to keep the temperature of the first chamber within a suitable temperature range and reduce the impact of the temperature on components such as the control unit 2. The cover 4 is made of a transparent material, which can be PVC or glass, etc., and can be set according to actual needs. The cover 4 has a curved surface structure, such as Figure 1 An embodiment of a curved surface structure is shown. For ease of description, the concave side of the curved surface structure is referred to as the second chamber. The edge of the curved surface structure forms a second opening, which communicates with the second chamber. The second opening is sized to match the first opening. A cover plate 4 covers the first opening, and a first partition plate 3 is positioned on the plane of the first opening.

[0049] A first light-emitting diode 31 and a first photoresistor 32 are provided on the first partition 3. Specifically, in this embodiment, the first light-emitting diode group includes at least one first light-emitting diode 31. That is, multiple first light-emitting diodes 31 and multiple first photoresistors 32 can be provided as needed. Each of the multiple first light-emitting diodes 31 emits a first detection light beam a at a first preset frequency. As a preferred embodiment, one first light-emitting diode 31 and one first photoresistor 32 can be referred to as a first optical inspection group. By distributing the multiple first optical inspection groups in a matrix, light intensity inspection results of multiple first reflected light beams b are obtained. The light intensity inspection results of the multiple first reflected light beams b are used to determine whether the current safety positioning device is in a water-falling state, thereby further improving the accuracy of water-falling state inspection.

[0050] The first photoresistor 32 can receive the light signal emitted by the first light-emitting diode 31 (that is, the first detection light beam a) after being reflected by the cover plate 4 and refracted / scattered by the medium outside the cabin. The control unit 2 determines the falling into water situation based on the change in light intensity received by the first photoresistor 32, thereby realizing the falling into water and sinking ship alarm.

[0051] A photoresistor, also known as a photoconductive detector, utilizes the photoconductive effect of a semiconductor to change its resistance value with the intensity of incident light. For ease of illustration, the photoresistor shown in this embodiment is referred to as first photoresistor 32. The analog output of first photoresistor 32 is connected to the AD module of control unit 2. The AD module converts the analog output into a precise value of light intensity, measured in lux. Typically, a photoresistor is selected in which the resistance decreases with stronger incident light and increases with weaker incident light.

[0052] Because light refracts when traveling through air and water, its direction of propagation changes due to the different media. The light signal emitted by the LED is reflected by the curved transparent cover, and the photoreceptor detects changes in the intensity of the reflected light. The outer surface of cover 4 reflects different intensities in air and water, and the changes in reflected light intensity are quite significant. The intensity of the reflected light can be used to determine whether the device has fallen into water, providing a water fall warning.

[0053] Based on this principle, when in use, this embodiment detects changes in the current external environment of the safety positioning device by controlling the first light-emitting diode 31 to emit the first detection beam a at a first preset frequency and obtaining the light intensity of the first detection beam a collected by the first photoresistor 32. Since light refraction occurs when propagating through air and water, the propagation direction of light changes due to the different media when it enters water from air. The outer side of the curved surface structure of the cover plate 4 reflects the first reflected beam b in different intensities in air and water, and the changes are quite significant. Based on the intensity of the first reflected beam b, it can be determined whether the safety positioning device has fallen into water, thus providing a water fall alarm warning. The control unit 2 uses the first photoresistor 32 to collect the light intensity of the first reflected beam b generated by the first light-emitting diode 31 on the cover plate 4 to determine the water fall status, which provides a more rigorous judgment condition and reduces the probability of false alarms.

[0054] See also Figure 1 In some embodiments, a water sensor group is further included. The water sensor group is disposed on the base 1 and includes at least one water sensor 11. The detection end of the water sensor 11 is disposed toward the outside of the base 1 and is electrically connected to the control unit 2. In this embodiment, there may be multiple water sensors 11, and optionally, there are two water sensors 11. The water sensor 11 is a sensor device for detecting water level or flooding, and can detect the presence of water and output a corresponding signal. Based on the structure of the first photoresistor 32 and the first light-emitting diode 31, a water immersion sensor 11 can be further provided. The water immersion sensor 11 is provided on the base 1. Preferably, the water immersion sensor 11 is provided on the bottom surface of the base 1, and the detection end of the water immersion sensor 11 is provided toward the outside of the bottom surface of the base 1. When the entire safety positioning device is immersed in water, the water immersion sensor 11 can detect the problem of the current safety positioning device falling into water, and compare it with the detection results of the first photoresistor 32 and the first light-emitting diode 31. When the detection result of the water immersion sensor 11 is falling into water, and the detection results of the first photoresistor 32 and the first light-emitting diode 31 are also falling into water, it indicates that the current safety positioning device has fallen into water. This method can further increase the safety positioning device's detection of the falling-in-water state, improve the accuracy of the falling-in-water alarm, and reduce the probability of false alarms.

[0055] See also Figure 1 and Figure 4In some embodiments, the base 1 is symmetrically provided with a plurality of first holes at the edge of the first opening, and the cover 4 is symmetrically provided with a plurality of second holes at the edge of the second opening, wherein one first hole is coaxially arranged with one second hole, and the safety positioning device further comprises a second light-emitting diode 12 group and a second photoresistor group, the second light-emitting diode 12 group being arranged on the base 1, the second light-emitting diode 12 group including at least one second light-emitting diode 12, and one second light-emitting diode 12 being arranged on one of the first holes, and the first hole provided with the second light-emitting diode 12 being recorded as a first mounting hole, the second light-emitting diode 12 group being electrically connected to the control unit, and the second light-emitting diode 12 group emitting a second detection light beam at a second preset frequency. The second detection beam is projected onto the inner side wall of the second hole, and the transparent material of the cover plate 4 serves as the light propagation medium of the second detection beam; a second photoresistor group is arranged on the base 1, and the second photoresistor group includes at least one second photoresistor 14, and one second photoresistor 14 is arranged on one of the first holes. The first hole where the second photoresistor 14 is provided is recorded as a second mounting hole, and one first mounting hole is arranged opposite to one second mounting hole. The collection end of the second photoresistor 14 is placed in the second hole, and the second photoresistor 14 is used to collect the light intensity of the second detection beam transmitted through the cover plate 4. The second photoresistor group is electrically connected to the control unit.

[0056] In this embodiment, the second LED group includes at least one second LED 12. That is, multiple second LEDs 12 can be provided as needed. Similarly, multiple second photoresistors 14 can be provided as needed. Each of the multiple second LEDs 12 emits a second detection beam at a second preset frequency. As an optional embodiment, the second detection beams of the multiple second LEDs 12 have different spectra. On this basis, some of the second LEDs 12 can be configured to emit the second detection beam at the second preset frequency under normal operating conditions, while another portion of the second LEDs 12 can be configured to emit the second detection beam at the second preset frequency under normal operating conditions. This allows for further subdivision of the specific operating conditions of the safety positioning device.

[0057] In this embodiment, a plurality of first holes are provided at the first opening, and the first holes are symmetrically arranged. A plurality of second holes are provided at the second opening, and the second holes correspond to the first holes. During normal use, fasteners are locked in the first holes and the second holes, thereby realizing the connection between the cover 4 and the base 1. Furthermore, for ease of description, the first hole positions are used for explanation, and the relatively arranged first hole positions are denoted as the same group. The first opening has multiple groups of first hole positions. One of the first hole positions is selected for installation of the second light-emitting diode 12 and the second photoresistor 14. One first hole position in the same group is installed with the second light-emitting diode 12. For ease of distinction, this first hole position is denoted as the first installation hole. The second first hole position in the same group is installed with the second photoresistor 14. The other first hole position is denoted as the second installation hole. The MCU control unit controls the second light-emitting diode 12 to adopt a fixed or variable emission frequency. The light signal is transmitted along the curved surface of the curved transparent cover plate 4. When the cover plate 4 is disassembled or improperly assembled, incident light leaks, the light intensity received by the second photoresistor 14 is weakened, or the signal is out of sync with the second light-emitting diode 12. At this time, the MCU control unit recognizes that the disassembly light intensity channel is abnormal. The disassembly light intensity channel abnormality is the light intensity channel formed by the second light-emitting diode 12, the second photoresistor 14, and the cover plate 4, and generates a disassembly alarm prompt. To enhance interference resistance, a matrix-type optical signal receiving arrangement using the second photoresistors 14 can be employed. Specifically, multiple sets of oppositely positioned second photoresistors 14 and second light-emitting diodes 12 can be installed in the remaining mounting holes, forming a matrix-type distribution structure. By comparing the light intensity with the second photoresistors 14 in adjacent holes, external optical signal interference can be eliminated.

[0058] Specifically, the transparent cover plate 4 is a denser medium compared to air, which is a less dense medium. When light is incident from the denser medium to the less dense medium at an angle greater than the critical angle, total internal reflection occurs. Just like an optical fiber, the light can propagate along the transparent structure of the cover plate 4. Therefore, the second LED group 12 emits a second detection beam, which is reflected from the interior of the cover plate 4 and projected onto the second photoresistor group.

[0059] When the cover 4 is disassembled or not properly assembled, the light emitted by the second photoresistor group leaks and fails to be projected to the second photoresistor group through total reflection inside the cover 4. The light intensity received by the second photoresistor group is weakened or is out of sync with the emitted light, and the control unit generates a disassembly alarm prompt.

[0060] This method can realize real-time monitoring of the connection status between the cover plate 4 and the base 1, and is convenient for distinguishing abnormal problems of the safety positioning device according to actual conditions, so that users can make adjustments and modifications in time.

[0061] In some embodiments, a light-transmitting cover 13 is further included. The light-transmitting cover 13 is disposed on the bottom surface of the base 1. Specifically, the light-transmitting cover 13 is disposed directly below the third photoresistor 19 to transmit ambient light. Figure 1 As shown, the safety positioning device is also provided with a third photoresistor 19. The third photoresistor 19 is on the circuit board where the control unit 2 is located. The control unit 2 is arranged in the first chamber between the base 1 and the first partition 3. The third photoresistor 19 is only used to receive the ambient light transmitted by the light-transmitting cover 13 and is not interfered with by external light. After the safety positioning device is fixed on the surface of the mounting carrier (such as an external support structure), the bottom of the light-transmitting cover 13 is blocked, and there is no ambient light at this time. When the safety positioning device is removed from the mounting carrier, the third photoresistor 19 receives ambient light, and the resistance value of the third photoresistor 19 changes, which is then transmitted to the control unit to generate a disassembly alarm message. In addition, this process can also be combined with the latitude and longitude position information of the geographic coordinates collected by the control unit 2 and uploaded to the control center to achieve real-time tracking and detection of the safety positioning device, thereby improving the safety warning performance of the entire safety positioning device and the vessel.

[0062] See also Figure 1 In some embodiments, the device further includes a battery 5 and a first pressure plate 51. The battery 5 is disposed within the first chamber, adjacent to the control unit 2, and electrically connected to the control unit 2. One end of the first pressure plate 51 is disposed on the battery 5, and the other end of the first pressure plate 51 extends outward, contacting the first lower surface. In this embodiment, the battery 5 can be a lithium battery or other rechargeable battery. The outer housing of the battery 5 is provided with the first pressure plate 51, which can be made of an elastic material or a spring. When the first partition 3 is installed in the first opening, the first lower surface of the first partition 3 contacts one end of the first pressure plate 51, causing the first pressure plate 51 to deform, securing the battery 5 within the first chamber and preventing it from slipping during movement of the safety positioning device. The provision of the battery 5 provides the safety positioning device with an independent power supply, eliminating the need for cables or wiring harnesses on the vessel for power supply. This eliminates the need for interference with the vessel's hull circuitry and facilitates use.

[0063] See also Figure 1 In some embodiments, a first opening is further provided on the side of the base 1, and the positioning device further includes a charging interface 52, a sealing gasket 15 and a baffle 16. The charging interface 52 is provided on the battery 5, and the charging interface 52 is placed in the first opening; the sealing gasket 15 is provided on the base 1 and provided at the first opening, and the sealing gasket 15 is used to seal the first opening; the baffle 16 is provided on the base 1 and provided at the first opening, and the baffle 16 is provided on the outside of the sealing gasket 15.

[0064] In this embodiment, the charging interface 52 can be used to charge the battery 5. This method is suitable for scenarios where the battery 5 is low on power, such as using the solar panel 33 described later to charge the battery 5. When the solar panel 33 is damaged, the battery 5 can be charged through the charging interface 52, which facilitates troubleshooting.

[0065] In this embodiment, a baffle 16 and a sealing gasket 15 are provided. The sealing gasket 15 can be made of silicone material. The sealing gasket 15 seals the first opening and rests against the outer edge of the charging interface 52. The sealing gasket 15 can protect the charging interface 52. The baffle 16 can be a thin sheet structure made of metal material. In some optional embodiments, the baffle 16 can be locked with fasteners such as screws. The baffle 16 can tightly buckle the sealing gasket 15 at the first opening to further maintain the airtightness of the charging interface 52.

[0066] See also Figure 1 In some embodiments, the system further includes a solar panel 33 disposed above the first partition 3 and electrically connected to the battery 5. In this embodiment, the provision of the solar panel 33 addresses the issue of limited power for offshore operations, enabling autonomous power supply from the battery 5 and effectively utilizing offshore solar energy resources. Furthermore, the solar panel 33, disposed above the first partition 3, maximizes solar energy absorption through the transparent cover 4, improving solar energy conversion efficiency. This also reduces the area of ​​the first partition 3 exposed to sunlight, slowing the rate of temperature rise within the second chamber.

[0067] See also Figure 1 In some embodiments, a second opening is further provided on the side of the base 1, with the first opening and the second opening being arranged opposite each other. The positioning device further includes an alarm button 17, which is disposed on the base 1 at the second opening and is electrically connected to the control unit 2. When a manual alarm is required, the alarm signal can be manually triggered by pressing the alarm button 17 on the side of the safety positioning device, allowing the rescue team to promptly be aware of any abnormalities on the vessel and to initiate rescue operations.

[0068] See also Figure 1 In some embodiments, a sealing rubber ring 6 is further included. The sealing rubber ring 6 matches the shape of the first opening and is disposed between the first partition plate 3 and the first opening. In this embodiment, the sealing rubber ring 6 ensures an airtight connection between the first partition plate 3 and the first opening, while simultaneously isolating the air in the second chamber from the air in the first chamber. When the cover plate 4 is placed in an environment with high light intensity, the temperature in the second chamber rises suddenly. The provision of the sealing rubber ring 6 and the first partition plate 3 can reduce the impact of the temperature in the second chamber on the temperature in the first chamber, thereby extending the service life of components such as the control unit 2 and the battery 5.

[0069] In some embodiments, the base 1 is further provided with a third opening, which is disposed on the bottom surface of the base 1. The positioning device further includes a breathable valve 18, which is disposed at the third opening. In this embodiment, the breathable valve 18 is a device for controlling the inflow and outflow of gas. Its main function is to adjust or balance the pressure difference between the gas inside and outside the container to achieve gas permeability and exhaust. In this embodiment, a breathable valve 18 seal and a breathable valve 18 nut are further provided at the connection between the breathable valve 18 and the third opening, so that the breathable valve 18 can be airtightly connected to the base 1. The provision of the breathable valve 18 can balance the air pressure in the first chamber, prevent the air pressure change when falling into water from damaging the components in the safety positioning device, and improve the reusability of the entire safety positioning device.

[0070] In some embodiments, a positioning unit and a communication unit are also included. The positioning unit is integrated with the control unit 2 and is used to obtain the geographic location coordinates of the positioning device; the communication unit is integrated with the control unit 2 and is used to send digital signals outward.

[0071] In this embodiment, the positioning unit can be a Beidou positioning chip. The positioning unit, control unit 2, and communication unit are integrally formed. That is, the positioning unit, communication unit, and control unit 2 can be placed in the same circuit module. Control unit 2 is electrically connected to the positioning unit and communication unit. The positioning unit can obtain the geographic coordinates of the current safety positioning device in real time. The communication unit can promptly send a distress signal to an external rescue service terminal when the safety positioning device falls into the water, so that the rescue team can promptly be informed of the current abnormality of the ship and carry out rescue operations.

[0072] The shipborne safety positioning device includes a base 1, a control unit 2, a first partition 3, a cover 4, a first light-emitting diode group and a first photoresistor group. The cover 4 has a curved surface structure, and the second chamber is arranged on the concave side of the curved surface structure. The cover 4 is made of a transparent material; the first light-emitting diode group is arranged on the first upper surface, the first light-emitting diode group includes at least one first light-emitting diode 31, the first light-emitting diode group is electrically connected to the control unit 2, and the first light-emitting diode group emits a first detection light beam a according to a first preset frequency. The first detection light beam a is reflected by the concave side of the cover 4 to form a first reflected light beam b, and the first detection light beam a is transmitted through the cover 4 to form a first transmitted light beam c; the first photoresistor group is arranged on the first upper surface and is arranged opposite to the first light-emitting diode group. The first photoresistor group includes at least one first photoresistor 32, the first photoresistor group is electrically connected to the control unit 2, and the first photoresistor 32 is used to absorb the light intensity of the first reflected light beam b. During use, by controlling the first light-emitting diode 31 to emit the first detection beam a at a first preset frequency and obtaining the light intensity of the first detection beam a collected by the first photoresistor 32, changes in the external environment of the current safety positioning device are detected. Since light refraction occurs when it propagates in air and water, when light is emitted from air into water, the propagation direction will change due to the difference in the medium. The outer side of the curved surface structure of the cover plate 4 has different reflection intensities of the first reflected beam b in air and water, and the changes are more obvious. Based on the intensity of the first reflected beam b, it can be determined whether the safety positioning device has fallen into the water, realizing a water fall alarm warning. In this technical solution, the control unit 2 uses the first photoresistor 32 to collect the light intensity of the first reflected beam b generated by the first light-emitting diode 31 on the cover plate 4 to determine the water fall state. The judgment conditions are more rigorous and the probability of false alarms is reduced.
