Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to an aerial spectrum monitoring payload device. Background Art

[0002] A spectrum monitoring payload is a device or system used to monitor the electromagnetic spectrum. The Sky Survey Illegal Radiation Source Positioning System uses a radio direction-finding payload carried on an unmanned aerial vehicle platform to quickly and efficiently collect spectrum information of illegal radiation sources. Combined with advanced algorithm platforms and three-dimensional geographic visualization technology, it can dynamically display the direction and location information of the radiation source in real time.

[0003] Traditional aerial spectrum monitoring payloads also have the following drawbacks: First, when a traditional payload is operating, the core board inside it generates a large amount of heat. This heat can only be dissipated through the heat dissipation holes on the payload housing. However, due to the limitations of the heat dissipation holes, it is not possible to dissipate all the heat generated by the core board through the heat dissipation holes alone. In addition, the airborne spectrum monitoring payload needs to fly in the sky. Therefore, over long-term use, dust in the air may block the heat dissipation holes, ultimately affecting the heat dissipation efficiency of the core board. Secondly, since dust can enter the payload device casing during flight, the payload device needs to be cleaned regularly. Traditional payload devices require the core plate to be removed and then reinstalled before cleaning, which wastes a lot of time. Third, the interfaces for connecting communication lines or power lines on traditional payload devices usually need to be exposed outside the payload device to facilitate connection of communication lines or power lines. However, during the flight of the drone, dust will be driven by the wind and fall toward the payload device. The grit in the dust will cause wear on the interfaces, and the acidic substances in the dust will cause the interfaces to oxidize and rust, eventually rendering the core board unusable. Therefore, it is necessary to provide an aerial spectrum monitoring payload device to solve the above problems. Summary of the Invention

[0004] Based on this, it is necessary to provide an aerial spectrum monitoring payload device to address the existing technical problems.

[0020] When processing the core board 5, a wireless communication module, an action scheduling module and a flight control module are connected to the core board 5. The wireless communication module, the action scheduling module and the flight control module are all existing technologies, so they are not shown in the figure. A communication terminal is provided on the ground, and a sky survey spectrum direction finding software is installed in the communication terminal. The sky survey spectrum direction finding software is used for electromagnetic signal positioning, spectrum situation display and route parameter setting. In actual use, this payload device is installed on a UAV, and the payload device is carried by an unmanned mechanism to quickly and efficiently collect spectrum information of illegal radiation sources, and combined with the advanced algorithm platform and three-dimensional geographic visualization technology on the ground terminal, the direction and position information of the radiation source are dynamically displayed in real time, which is suitable for interference investigation of communication base stations, execution of radio control tasks and radio support for major events; The assembly process of this payload device is as follows: first, remove the fixed cover plate 2 from the top of the rectangular shell 1, and then place the core plate 5 flat in the rectangular shell 1. At this time, the core plate 5 is pushed up by a number of elastic connectors. After the core plate 5 is placed, the heat conduction module is attached to the top of the core plate 5, and the heat conduction module is connected to the adjustment mechanism. After the heat conduction module is installed, the quick-connect cover plate 4 is installed in the installation port 3. During this process, the heat conduction module is driven down by the adjustment mechanism, so that the core plate 5 that is attached to the heat conduction module through the elastic connector will be driven to move downward, and finally the core plate 5 is adjusted to align the built-in interface 6 and the external interface 7 thereon. After that, the fixed cover plate 2 is installed on the top of the rectangular shell 1 to complete the assembly of the entire payload device. When the payload device is assembled, fix the payload device on the drone; The core board 5 needs to be connected to a power cord when in actual use. When connecting the power cord, one end of the power cord is inserted into the corresponding internal interface 6 of the core board 5 along one of the external interfaces 7, and the other end of the power cord is connected to the internal power supply of the drone. When the drone is equipped with an external communication device that needs to be used in series with the payload device, the external communication device can be connected to other external interfaces 7 on the payload device via a communication line. When the core board 5 continues to work, it will generate heat. At this time, the heat of the core board 5 will be transferred to the heat conduction module through heat conduction. At the same time, the exhaust fan 8 is started, and the heat emitted by the heat conduction module will eventually be discharged by the exhaust fan. When the UAV is flying, the load device will be subjected to wind force opposite to the flight direction of the UAV. During this process, the flowing wind will be poured into the drainage module, and the flowing wind will be introduced into the core board 5 in the rectangular shell 1 through the drainage module, so as to accelerate the heat dissipation of the core board 5 through the external flowing wind, thereby improving the heat dissipation efficiency of the core board 5.

[0021] The specific number of elastic connectors is four, and the four elastic connectors correspond to the four end corners of the core plate 5 respectively. Each elastic connector includes a limit sleeve 9, a positioning pin 10 and a spring 11. The limit sleeve 9 is vertically fixed on the inner bottom wall of the rectangular shell 1. The upper end of the limit sleeve 9 is an open structure and the lower end is a closed structure. The positioning pin 10 and the spring 11 are both vertical. The positioning pin 10 presses the spring 11 downward into the limit sleeve 9. Positioning holes 12 are provided on the four end corners of the core plate 5. The positioning pin 10 passes upward through the corresponding positioning holes 12. A limit ring 13 is coaxially formed on the outer wall of the positioning pin 10, which contacts the bottom of the core plate 5 upward.

[0022] When installing the elastic connector into the rectangular shell 1, first fix the vertical limit sleeve 9 on the inner bottom wall of the rectangular shell 1, then put the spring 11 into the limit sleeve 9, and finally insert the positioning pin 10 downward into the limit sleeve 9. At this time, the positioning pin 10 can be bounced up after being pressed down by the spring 11. When placing the core plate 5 into the rectangular shell 1, first align the four positioning holes 12 of the core plate 5 with the four positioning pins 10, and then lower the core plate 5 into the rectangular shell 1. Then, during the process of the core plate 5 descending, each positioning pin 10 will be inserted upward into the corresponding positioning hole 12, and finally, the core plate 5 will be fixed by the upper limit ring 13 of each positioning pin 10. The corresponding end corners of the core plate 5 are lifted up. At this time, the core plate 5 cannot move laterally and can only be raised and lowered. When processing the limit sleeve 9 and the spring 11, the limit sleeve 9 and the spring 11 have a certain length. In this way, while ensuring that the core plate 5 can be upwardly attached to the heat conduction module through the spring 11, the core plate 5 can be driven down by adjusting the height of the heat conduction module, and finally the built-in interface 6 on the core plate 5 can correspond to the external interface 7 on the quick-connect cover 4. When processing the rectangular shell 1, the rectangular shell 1 is provided with an observation port 43 on the outer wall of the drainage module, and the observation port 43 is used to observe whether the built-in interface 6 corresponds to the external interface 7.

[0023] The heat conduction module includes a heat conduction plate 14 and a plurality of heat dissipation fins 15. The heat conduction plate 14 is arranged horizontally. The plurality of heat dissipation fins 15 are evenly distributed on the top of the heat conduction plate 14 along the horizontal direction, and each heat dissipation fin 15 is horizontal. A plurality of heat dissipation silicone greases 16 are provided between the heat conduction plate 14 and the core plate 5.

[0024] When installing the thermal conductive module, first attach several heat dissipating silicone greases 16 to the bottom of the thermal conductive plate 14, then attach the thermal conductive plate 14 downward to the top of the core plate 5, and finally connect the thermal conductive plate 14 to the adjustment mechanism. When the core plate 5 is working, the heat emitted by the core plate 5 will be transferred to the several heat dissipating fins 15 through the thermal conductive plate 14, and finally the heat will be dissipated through the several heat dissipating fins 15. The heat dissipating silicone grease 16 arranged between the thermal conductive plate 14 and the core plate 5 is a functional material used in the field of heat dissipation of electronic equipment. Its core function is to fill the tiny gap between the heating element and the heat dissipation device, reduce the air barrier during the heat conduction process, and thus improve the heat transfer efficiency.

[0025] The adjustment mechanism includes an adjusting bolt 17, an internal threaded sleeve 18 and a lifting frame 19. A thickened seat 20 is formed at the bottom of the rectangular shell 1. An accommodating cavity 21 is opened upward at the bottom of the thickened seat 20. Vertically downward support plates 22 are formed on both sides of the heat conducting plate 14. Two symmetrical limiting columns 23 are fixed to the bottom of each support plate 22 and penetrate vertically downward into the accommodating cavity 21. The lifting frame 19 is arranged in the accommodating cavity 21. Each limiting column 23 is fixedly connected to the lifting frame 19. The adjusting bolt 17 is vertically arranged in the accommodating cavity 21. The upper end of the adjusting bolt 17 is rotatably connected to the thickened seat 20. The internal threaded sleeve 18 is fixedly connected to the lifting frame 19, and the adjusting bolt 17 is threadedly matched with the internal threaded sleeve 18.

[0026] The heat conducting plate 14 realizes its own sliding through several limiting columns 23 passing through the thickened seat 20. When the height of the heat conducting module needs to be adjusted, the adjusting bolt 17 is rotated, and the adjusting bolt 17 will drive the lifting frame 19 to descend through the internal threaded sleeve 18. The lifting frame 19 will drive the heat conducting plate 14 to descend through the limiting columns 23, and finally the core plate 5 that is in contact with the heat conducting plate 14 will be driven down by the heat conducting plate 14.

[0027] A vertically upward cylindrical shell 24 is formed on the inner bottom wall of the rectangular shell 1. The lower end of the cylindrical shell 24 is an open structure and is connected to the accommodating cavity 21. A ball bearing 25 is fixedly embedded in the cylindrical shell 24. The upper end of the adjusting bolt 17 is a smooth end, and the upper end of the adjusting bolt 17 is connected to the ball bearing 25.

[0028] When the adjusting bolt 17 is connected to the ball bearing 25 , the upper end of the adjusting bolt 17 is interference fit with the ball bearing 25 , thereby limiting the axial displacement of the adjusting bolt 17 and ensuring that the adjusting bolt 17 can only rotate.

[0029] Two symmetrical No. 1 bayonet pins 26 are formed on the outer wall of the lower end of each quick-connect cover plate 4, and each No. 1 bayonet pin 26 is horizontal. Two fixed pin sleeves 27 are formed on the outer wall of the rectangular shell 1 with the installation opening 3, and each No. 1 bayonet pin 26 is engaged with the corresponding fixed pin sleeve 27. The upper end of each quick-connect cover plate 4 is hinged with two symmetrical movable pin sleeves 28. Two No. 2 bayonet pins 29 are formed on the inner wall of the rectangular shell 1 with the installation opening 3, and each No. 2 bayonet pin 29 is horizontal. Each No. 2 bayonet pin 29 is engaged with the corresponding movable pin sleeve 28.

[0030] When processing the fixed pin sleeve 27 and the movable pin sleeve 28, notches are provided on the fixed pin sleeve 27 and the movable pin sleeve 28. The notches make the fixed pin sleeve 27 and the movable pin sleeve 28 have a certain elastic deformation ability. When installing the quick-connect cover 4, first press the No. 1 bayonet 26 on the lower end of the quick-connect cover 4 into the corresponding fixed pin sleeve 27, so that the quick-connect cover 4 can be flipped up or down (such as Figure 15 As shown), thereafter, the quick-connect cover plate 4 is flipped upward to a vertical state, and the No. 2 bayonet pin 29 is pressed into the corresponding movable pin sleeve 28, thereby completing the installation of the quick-connect cover plate 4, wherein the movable pin sleeve 28 can be rotated, so that after the quick-connect cover plate 4 is flipped upward, by rotating the movable pin sleeve 28, the notch on the movable pin sleeve 28 can correspond to the No. 2 bayonet pin 29, so that the No. 2 bayonet pin 29 is pressed into the movable pin sleeve 28. After the load device has been used for a period of time, the No. 2 bayonet pin 29 and the movable pin sleeve 28 can be manually separated, so that the quick-connect cover plate 4 can be flipped downward to expose the installation opening 3, and finally the interior of the rectangular shell 1, especially the bottom of the core plate 5, is cleaned through the installation opening 3.

[0031] Connecting platforms 30 are formed on the four inner corners of the rectangular shell 1, and four downwardly concave corner grooves 31 are formed on the top of the fixed cover 2. The four corner grooves 31 correspond to the four corners of the rectangular shell 1 respectively, and each corner groove 31 is provided with a screw hole 32 corresponding to the connecting platform 30.

[0032] When installing the fixed cover plate 2 , place the fixed cover plate 2 flat on the top of the rectangular housing 1 , and align each end angle groove 31 with the connecting platform 30 , and then screw the screws connected to the connecting platform 30 into the screw holes 32 .

[0033] Each quick-connect cover plate 4 is provided with a plurality of sockets 33 on one end of the movable pin sleeve 28 , and a plurality of vertically downward pins 34 are formed on both ends of the fixed cover plate 2 , and each pin 34 is inserted downward into the corresponding socket 33 .

[0034] Before installing the fixed cover 2, first install the quick-connect cover 4. When the quick-connect cover 4 is flipped upward until the No. 2 bayonet 29 is pressed into the movable pin sleeve 28, the quick-connect cover 4 is in a vertical state. Thereafter, the fixed cover 2 is placed flat on the top of the rectangular housing 1. During this process, the pin 34 provided on the fixed cover 2 will be inserted downward into the corresponding socket 33, thereby preventing the quick-connect cover 4 from loosening through the fixed cover 2.

[0035] Each drainage module includes an air guide shell 35 and a partition 36. The air guide shell 35 is rectangular and fixedly connected to the side wall of the rectangular shell 1. The partition 36 is arranged in the air guide shell 35. The partition 36 divides the inner cavity of the air guide shell 35 into two symmetrical air guide cavities 37. Air inlets 38 are provided at both ends of the air guide shell 35. Each air inlet 38 is connected to the corresponding air guide cavity 37. Two air outlets 39 are provided on the side wall of the air guide shell 35 facing the rectangular shell 1. Each air outlet 39 connects the corresponding air guide cavity 37 with the inner cavity of the rectangular shell 1.

[0036] When a drone is flying with this payload device, the payload device will be subjected to wind force in the opposite direction of the drone's flight. During this process, the flowing wind will be poured into the air guide cavity 37 through the air inlet 38, and the flowing wind will flow into the rectangular shell 1 from the air outlet 39 along the air guide cavity 37, and finally the heat dissipation of the core board 5 will be accelerated by the flowing wind. Since there are two air guide cavities 37 in each air guide shell 35, the flowing wind can be poured into the air guide cavity 37 through the corresponding air inlet 38 regardless of whether the drone is moving forward or backward.

[0037] A vertically upward mounting shell 40 is formed on the top of the fixed cover plate 2. The bottom of the mounting shell 40 is an open structure. A rectangular opening 41 connected to the mounting shell 40 is opened on the fixed cover plate 2. The exhaust fan 8 is fixed in the mounting shell 40. Several heat dissipation slots 42 are opened on the top of the mounting shell 40.

[0038] When the core board 5 is working, the heat generated by the core board 5 will be transferred to the plurality of heat dissipation fins 15. At this time, the exhaust fan 8 is started, and the heat emitted by the heat dissipation fins 15 will be discharged from the heat dissipation slot 42 through the exhaust fan.

[0039] Working principle: When processing the core board 5, a wireless communication module, an action scheduling module and a flight control module are connected to the core board 5. The wireless communication module, the action scheduling module and the flight control module are all existing technologies, so they are not shown in the figure. A communication terminal is provided on the ground, and a sky survey spectrum direction finding software is installed in the communication terminal. The sky survey spectrum direction finding software is used for electromagnetic signal positioning, spectrum situation display and route parameter setting. In actual use, this payload device is installed on a UAV, and the payload device is carried by an unmanned mechanism to quickly and efficiently collect spectrum information of illegal radiation sources, and combined with the advanced algorithm platform and three-dimensional geographic visualization technology on the ground terminal, the direction and position information of the radiation source are dynamically displayed in real time, which is suitable for interference investigation of communication base stations, execution of radio control tasks and radio support for major events; The assembly process of this payload device is as follows: first, remove the fixed cover plate 2 from the top of the rectangular shell 1, and then place the core plate 5 flat in the rectangular shell 1. At this time, the core plate 5 is pushed up by a number of elastic connectors. After the core plate 5 is placed, the heat conduction module is attached to the top of the core plate 5, and the heat conduction module is connected to the adjustment mechanism. After the heat conduction module is installed, the quick-connect cover plate 4 is installed in the installation port 3. During this process, the heat conduction module is driven down by the adjustment mechanism, so that the core plate 5 that is attached to the heat conduction module through the elastic connector will be driven to move downward, and finally the core plate 5 is adjusted to align the built-in interface 6 and the external interface 7 thereon. After that, the fixed cover plate 2 is installed on the top of the rectangular shell 1 to complete the assembly of the entire payload device. When the payload device is assembled, fix the payload device on the drone; The core board 5 needs to be connected to a power cord when in actual use. When connecting the power cord, one end of the power cord is inserted into the corresponding internal interface 6 of the core board 5 along one of the external interfaces 7, and the other end of the power cord is connected to the internal power supply of the drone. When the drone is equipped with an external communication device that needs to be used in series with the payload device, the external communication device can be connected to other external interfaces 7 on the payload device via a communication line. When the core board 5 continues to work, it will generate heat. At this time, the heat of the core board 5 will be transferred to the heat conduction module through heat conduction. At the same time, the exhaust fan 8 is started, and the heat emitted by the heat conduction module will eventually be discharged by the exhaust fan. When the UAV is flying, the load device will be subjected to wind force opposite to the flight direction of the UAV. During this process, the flowing wind will be poured into the drainage module, and the flowing wind will be introduced into the core board 5 in the rectangular shell 1 through the drainage module, so as to accelerate the heat dissipation of the core board 5 through the external flowing wind, thereby improving the heat dissipation efficiency of the core board 5.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
