Description

Technical Field

[0001] The utility model relates to the field of perception technology, and in particular to an integrated unmanned aerial vehicle perception device. Background Art

[0002] Sensing devices are increasingly being used in many fields such as roadside sensing.

[0003] Roadside sensing devices usually include multiple sensors such as cameras, millimeter-wave radars, and lidars, as well as computing modules that communicate with these sensors and external systems to achieve intelligent perception of road traffic participants, road conditions, etc.

[0004] In order to achieve miniaturization, construction consistency, and convenient sensor calibration, roadside sensing devices are moving towards an integrated design. When multiple sensors and computing modules are integrated together, how to effectively dissipate heat for the entire device becomes an urgent problem to be solved.

[0005] Patent CN216622681U discloses an integrated road-side fusion perception device, including: a protective shell, a back plate, an industrial camera fixedly installed in the protective shell, a laser radar sensor, a lens module, and a millimeter-wave radar. In the solution of this patent, heat dissipation is achieved by setting fins on the back plate. However, when a more complex computing module and / or multiple sensors are integrated in the road-side device, it is not enough to rely solely on the fins on the back plate to achieve heat dissipation.

[0006] The use of drones is becoming more and more widespread, but this also poses a security threat, so it is necessary to use drone detection devices to regulate the flight of drones.

[0007] Patent CN210109322U discloses a drone detection device that integrates video surveillance and active radar, including a radar host and multiple cameras. When the drone detection device detects drones in the airspace, the left camera, right camera and top camera form a wide-angle camera to shoot the detected drones, and transmit the shot images to the video display screen for playback. At the same time, the radar is combined with the position information to closely track the drone. However, in the solution of this patent, the radar host is set at the bottom of the device, and multiple cameras are set at the top of the device through a support rod. The two are set relatively far apart, resulting in a large volume of the entire device and inconvenient sensor calibration.

[0008] In order to achieve the goals of miniaturization, construction consistency, and convenient sensor calibration, it is necessary to carry out an integrated design for the UAV detection device and consider the overall heat dissipation of the integrated structure. Utility Model Content

[0049] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0050] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0051] As mentioned in the above background technology, the inventors of the present application recognize that in some schemes of the prior art, the structure and function of the sensing device are relatively simple, and the corresponding heat generation is relatively small. In this case, the heat dissipation of the entire device can be achieved only by, for example, a rear cover plate provided with heat dissipation fins. However, in the case where the structure and function of the sensing device are more complex, the entire device will generate a large amount of heat, and correspondingly higher heat dissipation requirements are proposed, and the heat dissipation method of the rear cover plate in the prior art is difficult to cope with such higher heat dissipation requirements. The inventors realize that in the schemes of the prior art, the heat of the entire device is usually dissipated through a unified path, and the heat generated by different components in the device is superimposed and then uniformly dissipated, which increases the difficulty of heat dissipation. Based on this, the present application proposes one or more embodiments to be described below, by reasonably dividing the heat dissipation of different heat-generating components of the entire device and dissipating them separately, thereby reducing the difficulty of heat dissipation and achieving effective heat dissipation of the device.

[0052] Figure 1 An exploded view of the integrated sensing device 100 according to an embodiment of the present utility model is shown. Figures 2 to 4 Schematic diagrams showing multiple different viewing angles of the integrated sensing device 100 are shown. In this embodiment, the integrated sensing device 100 is suitable for the roadside, that is, a roadside sensing device. Figures 1 to 4 The integrated sensing device 100 includes: a shell 10, the shell 10 includes a front cover 12 and a back cover 14 connected to each other; and a computing module 20, a millimeter-wave radar 30 and optionally at least one camera arranged in the shell 10; wherein the computing module 20 is fixed to the back cover 14 and is thermally connected to the back cover 14; the front cover 12 has a receiving groove 122 and a ventilation groove 125, the millimeter-wave radar 30 is at least partially embedded in the receiving groove 122, and the ventilation groove 125 connects the receiving groove 122 with the external environment.

[0053] In the embodiment of the utility model, the computing module 20 and the millimeter wave radar 30 of the integrated sensing device 100 are cooled separately, wherein the computing module 20 is thermally connected to the rear cover 14 so as to dissipate heat through the rear cover 14, and the millimeter wave radar 30 dissipates heat through the ventilation slots 125 of the front cover 12. By reasonably dividing the heat of the integrated sensing device 100 and dissipating it separately, the problem of increased difficulty in heat dissipation due to uniform heat dissipation after heat superposition can be avoided, and effective heat dissipation of the entire device can be finally achieved. By reasonably arranging the heat dissipation, the desired heat dissipation effect can also be achieved on the basis of simplifying the heat dissipation structure. The millimeter wave radar 30 is embedded in the receiving groove 122 of the front cover 12. On the one hand, a gap can be formed between the millimeter wave radar 30 and the computing module 20 (the millimeter wave radar 30 is arranged on the front cover 12, and the computing module 20 is arranged on the rear cover 14, one in front of the other), so that the heat generated by the two is separated and the heat is prevented from being superimposed as much as possible; on the other hand, the heat generated by the millimeter wave radar 30 can be concentrated in the receiving groove 122 and dissipated through the ventilation groove 125 connected to the receiving groove 122, further reducing the heat of the millimeter wave radar 30 flowing to the rear side. Since metal will interfere with the millimeter wave radar 30, the front cover 12 needs to be made of non-metallic materials such as plastic, and the thermal conductivity of non-metallic materials is poor. Therefore, the utility model dissipates heat by providing ventilation grooves 125.

[0054] In some embodiments, the computing module 20 integrates the following functional modules: 5G transmission module, WIFI module, Bluetooth module, positioning module, so that the computing module 20 has multiple communication functions, can communicate with different external objects (including various traffic participants, traffic information collection systems, traffic information display platforms, etc.) under various conditions, and has good adaptability. The computing module 20 has a positioning function to provide the location information of the perceived road section, which is convenient for the supervision system to manage and query the traffic information of different sections. The utility model adopts a computing module 20 with more complex functions and more heat generation than the prior art, and accordingly the utility model designs an improved heat dissipation solution as described above and further described below.

[0055] In some embodiments, the millimeter wave radar 30 is a 4D millimeter wave radar, 4D refers to the four dimensions of speed, distance, horizontal angle, and vertical height. The 4D millimeter wave radar is an upgraded version of the traditional millimeter wave radar. Compared with the traditional 3D millimeter wave radar, the 4D millimeter wave radar adds "height" detection and integrates the fourth dimension into the traditional millimeter wave radar. The 4D millimeter wave radar can break through the limitations in stationary target recognition, lateral movement detection, height recognition, distinguishing adjacent objects, and detecting hidden vehicles. The use of 4D millimeter wave radar also puts forward higher requirements for heat dissipation, and the heat dissipation solution of the utility model can meet its heat dissipation requirements.

[0056] refer to Figure 1 In some embodiments, a plurality of heat dissipation fins 142 are disposed on the outer side of the back cover 14, and a heat conductive member 144 is disposed on the inner side of the back cover 14. The heat conductive member 144 includes a heat conductive sheet 145 in contact with the maximum heat source on the computing module 20 and at least one heat pipe 147 extending from the heat conductive sheet 145 and thermally connected to the heat dissipation fins 142. The back cover 14 may be made of a thermally conductive material (e.g., aluminum). The heat generated by the maximum heat source on the computing module 20 is conducted to the heat pipe 147 via the heat conductive sheet 145, and then conducted from the heat pipe 147 to the back cover 14, and finally the heat is transferred to the surrounding environment via the heat dissipation fins 142. A receiving groove for receiving the heat pipe 147 may be disposed on the inner side of the back cover 14, and the receiving groove has a matching shape with the heat pipe 147. The shape and path of the heat pipe 147 can be set according to the arrangement of the components of the computing module 20, so that the heat pipe 147 avoids the secondary heat generating components other than the largest heat source on the computing module 20 as much as possible, ensuring that the heat pipe 147 is mainly used for heat conduction of the largest heat source, improving the heat dissipation efficiency of the largest heat source, while the secondary heat generating components can directly conduct heat to the back cover 14 to achieve heat dissipation. Figure 1 In the illustrated embodiment, the heat conducting member 144 may include two heat pipes 147, each heat pipe 147 is L-shaped, and the heat conducting member 144 is generally U-shaped. Of course, other numbers and shapes of heat pipes may be provided according to actual conditions.

[0057] The accommodating groove 122 may have a front opening to allow the transmitting panel of the millimeter wave radar 30 to be exposed, so as to avoid blocking the electromagnetic waves emitted by the millimeter wave radar 30 and affecting the detection. The ventilation groove 125 may penetrate multiple sides of the front cover 12 to form air circulation to take away heat and improve the heat dissipation efficiency.

[0058] refer to Figure 1The front cover 12 may include a body 121 and a radar protection cover 124 connected to the body 121. The body 121 forms a receiving groove 122. The surface where the radar protection cover 124 and the body 121 are connected is provided with a ventilation groove 125. The body 121 and the radar protection cover 124 formed separately are convenient for processing and manufacturing. The radar protection cover 124 is arranged on the front side of the body 121. The radar protection cover 124 is provided with an opening running through the front and back sides thereof, which corresponds to the front opening of the receiving groove 122, and is used to expose the transmitting panel of the millimeter wave radar 30 to allow the beam of the millimeter wave radar 30 to be emitted outward. The shape and size of the opening match the millimeter wave radar 30, and the opening may be arranged in the middle area of ​​the radar protection cover 124. The back of the radar protection cover 124 is provided with a ventilation groove 125. The ventilation groove 125 may run through multiple sides of the radar protection cover 124 (for example, the sides around the radar protection cover 124), which is conducive to forming air circulation to take away heat and improve heat dissipation efficiency. The ventilation slot 125 may be, for example, a cross shape, including two long grooves that intersect and penetrate two pairs of opposite sides. Of course, it may be other shapes as long as the accommodating slot 122 can be connected to the outside world. The width of the ventilation slot 125 may be greater than the width of the millimeter-wave radar, and the projection of the millimeter-wave radar on the back of the radar protection cover 124 may be located in the ventilation slot 125, which is conducive to sufficient heat dissipation. The opening of the ventilation slot 125 may be set to be thinner to reduce the risk of dust and water from the outside entering therein. A waterproof and breathable membrane may also be provided at the opening of the ventilation slot 125 to improve the waterproof performance.

[0059] At least one camera in the integrated sensing device 100 can be fixed to the back cover 14 and thermally connected to the back cover 14. Figure 1 In some embodiments, at least one camera provided in the device 100 includes a front-view camera 40, and the device 100 includes a heat-conducting camera bracket 42, and the front-view camera 40 is heat-conductingly connected to the rear cover 14 through the camera bracket 42. As described above, in order to avoid interference with the millimeter-wave radar 30, the front cover 12 is made of non-metallic materials such as plastic, which have poor thermal conductivity. Therefore, the utility model connects the front-view camera 40 to the rear cover 14 (the rear cover can be made of heat-conducting materials such as metal) through heat conduction to achieve heat dissipation. In the prior art, the front-view camera is usually installed on the front cover nearby. Different from the prior art, the utility model considers the heat dissipation problem of the front-view camera 40 and installs it on the rear cover 14 through the camera bracket 42. The camera bracket 42 can be set longer in the front-to-back direction to install the front-view camera 40 on the rear cover 14, and the camera bracket 42 can be made of heat-conducting materials such as metal. The front-view camera 40 is not connected to the front cover 12 (there is a gap or slight contact between the two) to avoid transferring heat to the front cover 12 as much as possible.

[0060] In the embodiment of the utility model, the integrated sensing device 100 adopts a passive heat dissipation method and does not provide a heat dissipation fan. If a fan is provided in the housing 10, the heat generated by the computing module 20, the millimeter wave radar 30 and the camera may flow together, which is not conducive to separate heat dissipation. At the same time, the utility model can achieve the required heat dissipation effect through a relatively simplified heat dissipation structure without using a fan.

[0061] refer to Figures 2 to 4 In some embodiments, the device 100 further includes a sunshade heat dissipation cover 60 disposed on the upper side of the housing 10, and a plurality of protrusions 62 (e.g., strip-shaped protrusions) arranged at intervals and engaging with the surface of the housing 10 are formed on the lower surface of the sunshade heat dissipation cover 60, and air guide grooves 64 are formed between adjacent protrusions 62. The sunshade heat dissipation cover 60 can prevent sunlight from directly shining on the housing 10 and causing the temperature to rise. The sunshade heat dissipation cover 60 may include a horizontal plate and an inclined plate inclined downward toward the rear side, and the inclined plate may increase the shading area. The front side does not have an inclined plate to avoid blocking the front-view camera 50. The plurality of spaced protrusions 62 disposed on the sunshade heat dissipation cover 60 allow a gap to exist between the lower surface of the sunshade heat dissipation cover 60 and the housing 10 for heat dissipation, and the air guide grooves 64 may ensure air convection.

[0062] refer to Figure 1 , at least one camera provided in the device 100 includes a forward-looking camera 40 and / or a fisheye camera 50. The number of the forward-looking cameras 40 may be two, and the two forward-looking cameras 40 respectively have a telephoto lens and a short-focus lens, so that they can shoot farther and wider. An opening may be provided on the front cover 12, so that the forward-looking camera 40 shoots through the opening, and a transparent camera protective cover 11 may be provided in the opening. The two forward-looking cameras 40 may be arranged at intervals in the lateral direction, so that the two cameras respectively shoot the lanes on both sides of the road. The distance between the two forward-looking cameras 40 ensures that the shooting areas of the two cameras have overlapping parts. The two forward-looking cameras 40 may be arranged on both sides above the millimeter-wave radar 30, so that the entire device 100 has a more regular and beautiful appearance. The fisheye camera 50 is used as a blind spot for peripheral vision, and mainly detects close objects around the device 100. The fisheye camera 50 is arranged at the lower part of the housing 10 and shoots downward. The fisheye camera 50 may pass through the bottom surface of the front cover 12 or the rear cover 14, and the housing 10 may further include a transparent camera protection cover 13 connected to the front cover 12 and / or the rear cover to protect the fisheye camera 50. The camera protection cover 13 may be hemispherical.

[0063] The device 100 includes at least one camera bracket (including a camera bracket 42 and / or a camera bracket 52) ​​fixed to the housing. The camera bracket 42 can adjust the front-view camera 40 to different shooting angles, and the camera bracket 52 can adjust the fisheye camera 50 to different shooting angles. In this way, for different installation scenarios and states, each camera can adjust the visual angle through the camera bracket to ensure the best visual visualization. For example, for the front-view camera 40, different downward tilt angles need to be set according to different road conditions. For the fisheye camera 50, it needs to always maintain a shooting angle perpendicular to the ground, but the overall installation angle of the device 100 is adjustable (for example, the device 100 is installed on an external mounting member through a universal joint). When the installation angle of the device 100 changes, the installation angle of the fisheye camera 50 needs to be adjusted accordingly to compensate, so that the fisheye camera 50 always shoots vertically downward.

[0064] refer to Figure 1 , Figure 5 and Figure 6 The camera bracket 42 includes a mounting bracket 422 fixed to the housing 10 and an adjustable bracket 424 for mounting the front view camera 40. The adjustable bracket 424 is provided with a first connecting portion 425. The mounting bracket 422 is provided with a plurality of groups of second connecting portions 423 that cooperate with the first connecting portion 425. Different groups of second connecting portions 423 are configured to form different mounting angles for the adjustable bracket 424. When the first connecting portion 425 is matched with different groups of second connecting portions 423, different shooting angles of the front view camera 40 can be achieved. The first connecting portion 425 and the second connecting portion 423 can be connecting holes, and the connection is achieved by the cooperation of fasteners and connecting holes. Of course, the first connecting portion 425 and the second connecting portion 423 can also be other connecting structures such as snap fittings that cooperate with each other. For different road sections, the shooting angle required for the front view camera 40 is different, for example, it can be 0 degrees, 5 degrees downward, 10 degrees downward, etc., so that the front view camera 40 can be adjusted to the required angle according to the road section monitored by the device 100. By adjusting the installation angle by cooperating the first connection portion 425 with different groups of second connection portions 423, it can be ensured that the adjusted angle can be stably maintained and will not be easily changed.

[0065] refer to Figure 5 and Figure 6 In some embodiments, the camera bracket 42 is also provided with a fill light 426 to ensure the shooting effect at night. Each camera bracket 42 can be provided with two fill lights 426, and the two fill lights 426 are respectively provided on both sides of the front camera 40. The fill lights 426 and the front camera 40 are integrated on the camera bracket 42 to form a modular structure, which is conducive to compact layout, reduced volume, and easy assembly and disassembly maintenance. A light sensor can be provided in the device 100, and the computing module 20 controls the opening and closing of the fill light based on the feedback information of the light sensor.

[0066] The camera bracket 42 may include a fill light bracket 427 connected to the mounting bracket 422, and the fill light 426 is mounted on the fill light bracket 427. Both the adjustable bracket 424 and the mounting bracket 422 may be U-shaped brackets, including two side panels and a rear panel. The first connecting portion 425 and the second connecting portion 423 are formed on the two side panels of the U-shaped bracket. The mounting bracket 422 has a longer length and can extend from the front to the rear of the device 100 and be fixed to the back cover 14. The adjustable bracket 424 has a shorter length and is disposed at the front of the mounting bracket 422. The fill light bracket 427 may be a U-shaped bracket and includes two side panels and a top panel, and the two fill lights 426 are respectively disposed on the flanges of the two side panels.

[0067] refer to Figure 1 and Figure 7 Similarly, the camera bracket 52 includes a mounting bracket 52 fixed to the housing 10 and an adjustable bracket 524 for mounting the fisheye camera 50, the adjustable bracket 524 is provided with a first connecting portion 525, and the mounting bracket 522 is provided with a plurality of groups of second connecting portions 523 cooperating with the first connecting portion 525, and different groups of second connecting portions 523 are configured to enable the adjustable bracket 524 to form different mounting angles. When the first connecting portion 525 is matched with different groups of second connecting portions 523, different shooting angles of the fisheye camera 50 can be achieved. The first connecting portion 525 and the second connecting portion 523 can be connecting holes, and the connection is achieved by the matching of fasteners and the connecting holes. Of course, the first connecting portion 525 and the second connecting portion 523 can also be other connecting structures such as buckles that match each other. By adjusting the mounting angle by matching the first connecting portion 525 with different groups of second connecting portions 523, it can be ensured that the adjusted angle can be stably maintained and will not be easily changed. The camera bracket 42 can be fixed to the back cover 14. The adjustable bracket 524 may be a U-shaped bracket including two side panels and a bottom panel. The mounting bracket 522 may be a U-shaped bracket including two side panels and a rear panel. The first connecting portion 525 and the second connecting portion 523 are formed on the two side panels of the U-shaped bracket. The mounting bracket 522 is relatively long and can extend from the middle of the device 100 to the rear and be fixed to the rear cover 14. The adjustable bracket 524 is relatively short and is disposed at the front of the mounting bracket 522.

[0071] Figure 8 An exploded view of an integrated sensing device 100' according to another embodiment of the present invention is shown. Fig. 9 A schematic diagram showing a perspective of the integrated sensing device 100'. In this embodiment, the integrated sensing device 100' is suitable for drone detection, that is, a drone sensing device. Compared with the integrated sensing device 100 for roadside in the previous embodiment, the integrated sensing device 100' for drone detection in this embodiment has the following differences:

[0072] The drone detection device 100' of this embodiment is mainly used to detect drones around the device. It can be hung on a signal base station tower, and multiple drone detection devices 100' for detection in multiple directions can be installed on one base station tower to ensure 360° visual monitoring without blind spots. The visual information can be synchronized to the user interface, and the detection information of the millimeter wave radar 30 is also reported to the user interface display.

[0073] The computing module 20 integrates the following functional modules: 5G transmission module 21, WIFI module and Bluetooth module 25, positioning module 23. The drone sends remote ID information via WIFI and / or Bluetooth, and the integrated sensing device 100' receives and parses the remote ID information through the WIFI module and Bluetooth module to form the latitude and longitude, altitude and serial number of the drone, which are displayed on the UI interface. After detecting an illegal drone, the integrated sensing device 100' will locate and report the location information of the device through the positioning module (GPS module) for the supervisor to review. The visual information, radar point cloud information, and remote ID information collected by the drone detection device 100 are sent to the UI interface through the 5G transmission module for display. The integrated sensing device 100' may also include a multi-channel omnidirectional antenna 24 electrically connected to the computing module 20 to ensure the transmission reliability of the entire machine's WIFI / Bluetooth module, 5G module, and GPS module. The multi-channel omnidirectional antenna 24 is connected to the antenna connector 22. The device 100' can form a multi-perception fusion of remote ID reception and analysis, 4D millimeter wave radar point cloud information, and high-definition visual information to form a multi-angle ring network to achieve the effect of low-altitude detection of drones.

[0074] The two front-view cameras 40 respectively shoot the two sides of the target area, and the distance between the two front-view cameras 40 ensures that the shooting areas of the two have overlapping parts. For the front-view camera 40, different tilt angles can be set according to different supervision areas. UAV detection does not require the fisheye camera 50 to shoot vertically downward. When the overall installation angle of the device 100' changes, the installation angle of the fisheye camera 50 can be adjusted accordingly to compensate.
