Description

Technical Field

[0001] This invention relates to the field of environmental protection, specifically to an electronic boundary marker system for the entire nature reserve based on BeiDou positioning. Background Technology

[0002] In order to monitor illegal crossings, border grazing, illegal logging and poaching in nature reserves, important nature reserves generally need to set up boundary management systems. Traditional physical boundary markers have limited functions and do not have monitoring and early warning capabilities. Therefore, existing technologies include electronic boundary marker systems that utilize the BeiDou satellite navigation system. Various monitoring devices are set up on the electronic boundary marker system, and data aggregation nodes are established to collect data and report it.

[0003] This complete system of electronic boundary markers, covering the entire boundary of the protected area and possessing dynamic intelligent sensing capabilities, plays an important role in the development of ecological protection areas. However, the power supply modules of electronic boundary markers generally use photovoltaic power generation and are equipped with energy storage batteries. During continuous rainy days, the energy storage batteries may experience insufficient power, causing intermittent monitoring effects of the electronic boundary markers. To compensate for the power supply, the simplest way is to replace the batteries manually or by drone. However, manual inspection and replacement are labor-intensive, and drone battery replacement has problems such as difficulty in large-scale deployment / recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a BeiDou-based electronic boundary marker system for the entire nature reserve, which solves the problem of high difficulty in replenishing power during the power generation downtime of existing electronic boundary markers.

[0005] The present invention achieves the above objectives through the following technical solutions: A Beidou-based electronic boundary marker system for the entire nature reserve includes multiple boundary marker units equipped with power generation components and Beidou positioning, deployed along the boundary line of the nature reserve, a convergence node, and a management platform. The convergence node is used to communicate with multiple boundary marker units to collect data and upload it to the management platform. The convergence node is also equipped with a battery transportation component for delivering and retrieving batteries to the boundary marker units during periods of low power generation. The battery transport assembly includes a drone and a box that is rotatably mounted on the bottom of the drone. The box has a vortex-shaped receiving cavity for accommodating batteries. The vortex-shaped receiving cavity has a center end and an edge end. The center end has a retrieval port and the edge end has a delivery port. The box rotates rapidly, causing the batteries in the vortex-shaped receiving cavity to be thrown one by one toward the delivery port. The boundary marker unit is equipped with a battery replacement assembly for raising and lowering the batteries.

[0006] As a preferred embodiment of the present invention, the boundary marker unit includes a boundary marker body, and the boundary marker body is also equipped with a main control unit, a microphone, and intelligent monitoring. The power generation component is a photovoltaic panel. This solution is the existing technology of electronic boundary markers. It integrates the main control unit of Beidou positioning, which can achieve accurate positioning. The microphone and intelligent monitoring can identify illegal activities such as logging. The intelligent monitoring can identify illegal crossings and other behaviors, which are the core functions of electronic boundary markers.

[0007] As a preferred embodiment of the present invention, both the recycling port and the dispensing port are provided with a rotating valve plate. The shaft of the valve plate is provided with a torsion spring to make the valve plate tend to close. A gap is left in the center of the closed valve plate. The top of the battery is provided with a chamfer to open the valve plate after the battery enters the gap of the valve plate. This embodiment, by setting a valve plate and cooperating with the chamfer of the battery, enables the battery to enter the recycling port in one direction and prevents it from falling.

[0008] As a preferred embodiment of the present invention, the boundary marker unit further includes a landing platform, on which a battery slot is provided, and the battery replacement component is disposed in the battery slot. This embodiment provides a landing platform to facilitate precise docking and landing of the UAV. Optionally, to improve docking accuracy, photoelectric sensors can be installed on the landing platform.

[0009] In a preferred embodiment of the present invention, the battery replacement assembly includes a lifting platform and a lifting seat slidably disposed on the lifting platform. The lifting seat is tended to be lifted by an elastic element disposed on the lifting platform. A sliding sleeve is also sleeved on the outside of the lifting seat. The top edge of the sliding sleeve is provided with an angle, and the bottom edge of the angle is provided with a flange. A groove is provided at the bottom of the battery to adapt to the top of the sliding sleeve, so as to open the valve plate when the sliding sleeve enters the delivery port and prevent the valve plate from closing when the battery falls. This solution achieves the battery recycling and delivery functions by setting the sliding sleeve and by different feed amounts of the lifting platform. When the battery is sent into the recycling port, the sliding sleeve does not enter the height of the valve plate. When the battery is removed, the sliding sleeve enters the groove, causing the valve plate to be opened, so as not to block the battery from falling.

[0010] In a preferred embodiment of the present invention, a column is provided on the lifting platform to guide the sliding of the lifting seat, and the elastic element is provided between the lifting seat and the column. In this embodiment, the column provides guidance for the lifting seat, and the elastic force of the elastic element can support the weight of the battery.

[0011] As a preferred embodiment of the present invention, the battery slot is further provided with a docking component for locking the battery and connecting it to power. This embodiment is the prior art, which achieves battery locking and power connection through the docking component.

[0012] In a preferred embodiment of the present invention, the drone is provided with at least one pair of landing gears, with a laterally extending rod at the bottom of the landing gears. A strip-shaped groove for accommodating the rod is provided on the landing platform, and a vortex-shaped guide groove is provided at the bottom of the drone. A lifting rod is provided on the landing platform, and the lifting rod cooperates with the vortex-shaped guide groove to drive the landing drone to translate along the rod by rotating the box, thereby aligning the battery slot with the delivery port. Several guide rollers are provided in the strip-shaped groove. In this embodiment, in order to move the battery slot from the aligned recovery port to the aligned delivery port, the vortex-shaped guide groove drives the box and the drone to translate under the drive of the box rotation. The amount of translation is controlled by the amount of box rotation. The guide rollers are provided to reduce the friction of translation.

[0013] As a preferred embodiment of the present invention, a lifting plate aligned with the recovery port is provided below the top wall of the inner box. This plate is used to fill the recovery port after the battery is thrown out, so as to prevent the battery from returning. By setting the lifting plate, the battery is thrown into the vortex-shaped receiving cavity by the rotating box and falls naturally, preventing the battery from returning. This makes the vortex-shaped receiving cavity tight and reliable, reducing shaking. The lifting plate can fall naturally or be assisted by a spring. However, the spring force cannot exceed the elasticity of the elastic element to prevent the elastic element from excessively retracting.

[0014] As a preferred embodiment of the present invention, the bottom of the drone is provided with a drive unit, the output shaft end of the drive unit is connected to the axis of the box body, the recovery port is located at the bottom of the box body near the center, and the axis of the recovery port does not coincide with the box body. This embodiment provides an eccentric recovery port so that centrifugal force can be generated during rotation, which can make the battery leave the valve plate support and enter the vortex-shaped receiving cavity. A ramp can also be provided on the upper edge of the recovery port to facilitate the battery entering the vortex-shaped receiving cavity.

[0015] The beneficial effects of the present invention are as follows: The present invention sets a landing platform on the boundary marker unit so that the battery transport component can replace the fully charged battery during the power generation off-peak period, effectively making up for the monitoring interruption problem during the power generation off-peak period. In addition, the battery transport component is equipped with a vortex-shaped receiving cavity to accommodate multiple batteries, and during replacement, the battery queue moves from the recovery port to the delivery port one by one, so that multiple boundary marker units can be replaced in one flight.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example 1

[0018] like Figure 1-6 As shown, a Beidou-based electronic boundary marker system for the entire nature reserve includes multiple boundary marker units 1 with power generation components 14 and Beidou positioning, deployed along the boundary line of the nature reserve, a convergence node, and a management platform. The convergence node is used to communicate with multiple boundary marker units 1 to collect data and upload it to the management platform. The convergence node is also equipped with a battery transport component 3 for delivering and retrieving batteries 4 to the boundary marker units 1 during periods of low power generation. The battery transport assembly 3 includes a drone 31 and a box 33 rotatably mounted on the bottom of the drone 31. The box 33 has a vortex-shaped receiving cavity 35 for accommodating batteries 4. The vortex-shaped receiving cavity 35 has a center end and an edge end. The center end has a retrieval port 36 and the edge end has a delivery port 37. The box 33 accelerates its rotation so that the batteries 4 in the vortex-shaped receiving cavity 35 are thrown one by one toward the delivery port 37. The boundary marker unit 1 is equipped with a battery replacement assembly 2 for raising and lowering the batteries 4.

[0019] This embodiment provides a landing platform 15 on the boundary marker unit 1, which allows the battery transport component 3 to replace the fully charged battery 4 during the power generation downtime, effectively compensating for the monitoring interruption problem during the power generation downtime. Furthermore, the battery transport component 3 is equipped with a vortex-shaped receiving cavity 35 to accommodate multiple batteries 4, and during replacement, the battery 4 queue moves one by one from the recovery port 36 to the delivery port 37, enabling the replacement of batteries 4 for multiple boundary marker units 1 in one flight.

[0020] During implementation, when environmental factors (such as weather) cause the power generation component 14 to enter a low power generation period, multiple boundary marker units 1 will experience insufficient power. A drone 31 carrying multiple fully charged batteries 4 will fly to the boundary marker unit 1, using Beidou positioning for navigation. Upon arrival, the drone will land and enter the raised batteries 4 through the recovery port 36. The fully charged batteries 4 will be lowered through the delivery port 37. Then, by rotating the box 33, the batteries 4 will move sequentially along the vortex-shaped receiving cavity 35 towards the delivery port 37, freeing up the recovery port 36 for the next recovery and delivery.

[0021] Preferably, the boundary marker unit 1 includes a boundary marker body 11, which is also equipped with a main control unit, a microphone 12, and an intelligent monitoring unit 13. The power generation component 14 is a photovoltaic panel. This solution is the existing technology of electronic boundary markers. It integrates a Beidou positioning main control unit, which can achieve accurate positioning. The microphone 12 and intelligent monitoring unit 13 can identify illegal activities such as logging. The intelligent monitoring unit can identify illegal crossings and other behaviors, which are the core functions of electronic boundary markers. Other monitoring devices can also be set up according to protection needs.

[0022] Preferably, both the recycling port 36 and the delivery port 37 are equipped with a rotating valve plate 38. The shaft of the valve plate 38 is equipped with a torsion spring to make the valve plate 38 tend to close. When the valve plate 38 is closed, there is a gap in the center. The top of the battery 4 is provided with a chamfer 41 to push open the valve plate 38 after the battery 4 enters the gap of the valve plate 38. This solution, by setting the valve plate 38 and cooperating with the chamfer 41 of the battery 4, enables the battery 4 to enter the recycling port 36 in one direction and prevents it from falling.

[0023] Optionally, the boundary marker unit 1 also includes a landing platform 15, on which a battery slot 18 is provided, and the battery replacement component 2 is located in the battery slot 18. This solution sets up a landing platform 15 to facilitate the precise docking and landing of the UAV 31. Furthermore, in order to improve the docking accuracy, photoelectric sensors can be set on the landing platform 15.

[0024] Preferably, the battery replacement assembly 2 includes a lifting platform 21 and a lifting seat 24 slidably disposed on the lifting platform 21. The lifting seat 24 is tended to be lifted by an elastic member 25 disposed on the lifting platform 21. A sliding sleeve 23 is also sleeved on the outside of the lifting seat 24. The top edge of the sliding sleeve 23 is provided with an angle, and the bottom edge of the angle is provided with a flange 26. The bottom of the battery 4 is provided with a groove 42 adapted to the top of the sliding sleeve 23 to open the valve plate 38 when the sliding sleeve 23 enters the delivery port 37 and to prevent the valve plate 38 from closing when the battery 4 falls. This solution achieves the battery 4 recycling and delivery functions by setting the sliding sleeve 23 and by different feed amounts of the lifting platform 21. When the battery 4 is sent into the recycling port 36, the sliding sleeve 23 does not enter the height of the valve plate 38 and will not prevent the valve plate 38 from closing. When the battery is removed, the sliding sleeve 23 enters the groove 42 to open the valve plate 38 and will not prevent the battery 4 from falling.

[0025] Preferably, a column 22 is provided on the lifting platform 21 to guide the sliding of the lifting seat 24, and an elastic element 25 is provided between the lifting seat 24 and the column 22. In this solution, the column 22 provides guidance for the lifting seat 24, and the elastic force of the elastic element 25 can support the weight of the battery 4.

[0026] Preferably, the battery compartment 18 is also provided with a docking component for locking the battery 4 and connecting it to power. This solution is the prior art, and the battery locking and power connection are achieved through the docking component.

[0027] Preferably, the drone 31 is provided with at least one pair of landing gears 32, with a horizontally extending rod at the bottom of the landing gear 32. The landing platform 15 is provided with a strip groove 16 to accommodate the rod, and the bottom of the drone 31 is provided with a vortex guide groove 39. The landing platform 15 is provided with a lifting rod 27, which is driven to rise and fall by a cylinder. The lifting rod 27 cooperates with the vortex guide groove 39 to move the drone 31 along the rod by rotating the box 33, thereby aligning the battery slot 18 with the delivery port 37. Several guide rollers 17 are provided in the strip groove 16. In this scheme, in order to move the battery slot 18 from the alignment with the recovery port 36 to the alignment with the delivery port 37, the vortex guide groove 39 is provided to drive the box 33 and the drone 31 to translate under the drive of the rotation of the box 33. The amount of translation is controlled by the rotation of the box 33. The guide rollers 17 are provided to reduce the friction of translation.

[0028] Preferably, a lifting plate 310 aligned with the recovery port 36 is provided below the inner top wall of the box 33. This plate is used to fill the recovery port 36 after the battery 4 is thrown out, so as to prevent the battery 4 from returning. In this solution, by setting the lifting plate 310, the battery 4 is thrown into the vortex-shaped receiving cavity 35 by the rotating box 33 and falls naturally, preventing the battery 4 from returning. This makes the vortex-shaped receiving cavity 35 tight and reliable, reducing shaking. The lifting plate 310 can fall naturally or a spring can be set to help it fall. However, the spring force cannot be higher than the elasticity of the elastic element 25 to prevent the elastic element 25 from excessively retracting.

[0029] Preferably, the drone 31 is provided with a drive unit 34 at the bottom. The output shaft end of the drive unit 34 is connected to the axis of the box 33. The recovery port 36 is located at the bottom of the box 33 near the center, and the axis of the recovery port 36 does not coincide with the box 33. This solution provides an eccentric recovery port 36 so that it has centrifugal force when rotating, which can make the battery 4 leave the valve plate 38 support and enter the vortex-shaped receiving cavity 35. The upper edge of the recovery port 36 can also be provided with a ramp so that the battery 4 can enter the vortex-shaped receiving cavity 35.

[0030] Working principle: When a battery swap is needed, the drone 31, carrying the housing 33, lands on the landing platform 15, and the landing gear 32 enters the strip groove 16, aligning the battery slot 18 with the recovery port 36. Driven by the lifting platform 21, the lifting seat 24 lifts the battery 4, which passes through the chamfer 41 into the center of the valve plate 38. The valve plate 38 is then pushed to both sides, allowing the battery 4 to enter the housing 33. The lifting feed of the lifting platform 21 prevents the sliding sleeve 23 from entering the groove 42. Figure 6 As shown, there is a gap between the sliding sleeve 23 and the bottom of the battery 4, which causes the valve plate 38 to close and be supported under the battery 4. At this time, the lifting platform 21 descends to complete the recycling of the battery 4. The lifting rod 27 rises and abuts against the outside of the vortex guide groove 39. The box 33 rotates slowly, and the vortex guide groove 39 pushes the box 33 and the drone 31 to slide along the strip groove 16. Finally, the battery slot 18 aligns with the delivery port 37. Then, the lifting platform 21 rises. The feed amount of the lifting platform 21 during this rise is greater than the feed amount during recovery. When the elastic force of the elastic element 25 is sufficient to support the battery 4, the lifting platform 21 continues to move upwards, causing the sliding cylinder 26 to move upwards and enter the groove 42, thereby opening the valve plate 38 and locking it outside the flange 26. As the lifting platform 21 moves downward, the elastic element 25 is excessively compressed during this process. The lifting seat 24 maintains a constant height, and the sliding sleeve 23 also maintains a constant height due to the jamming between the flange 26 and the valve plate 38. This continues until the lifting platform 21 descends to the point where the elastic force of the elastic element 25 is insufficient to support the weight of the battery 4. At this point, the battery 4 and the sliding sleeve 23 descend under their own weight. The valve plate 38 is then guided by the sliding sleeve 23 to the side wall of the battery 4, no longer obstructing the descent of the battery 4. After the battery 4 is successfully placed, it is locked and connected to the power supply. The lifting rod 27 descends, and the box 33 moves along... Figure 5 As the camera rotates counterclockwise at an accelerated speed, the batteries 4 are moved one by one due to inertia and centrifugal force. The next battery 4 enters the delivery port 37, leaving the recovery port 36 empty. The lifting plate 310 falls down, occupying the area of ​​the recovery port 36 to prevent the battery 4 from returning.

[0031] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
