Description

Technical Field

[0001] This utility model relates to the field of unmanned mobile equipment technology, specifically to a mobile platform video information acquisition and analysis device based on an intelligent operating system. Background Technology

[0002] In the application of mobile platforms such as drones, intelligent inspection robots, and engineering vehicles, the acquisition and intelligent analysis of real-time video information plays a crucial role. However, existing mobile platform video acquisition devices have some shortcomings when facing complex application scenarios: First, traditional acquisition devices mostly rely on a single visible light camera, which has limited perception dimensions and is difficult to work effectively in low light conditions such as nighttime, fog, or inclement weather. They also cannot simultaneously acquire multi-dimensional information such as target depth and thermal imaging, limiting the accuracy and application scope of subsequent analysis. Second, the continuous vibration and impact generated by the mobile platform during operation are directly transmitted to the device's internal components, seriously affecting the stable operation of core components such as the main control circuit board and coprocessor. This not only causes blurred and jittery images but may also damage the equipment due to long-term mechanical stress, shortening its service life. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to propose a mobile platform video information acquisition and analysis device based on an intelligent operating system, integrating multispectral sensing, effective vibration suppression, efficient heat dissipation, and a convenient installation interface.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a mobile platform video information acquisition and analysis device based on an intelligent operating system, comprising: a device housing; a multispectral light-transmitting cover, wherein the multispectral light-transmitting cover is disposed at one end of the device housing, and a mounting plate is provided inside the multispectral light-transmitting cover, wherein the mounting plate is provided with a main camera mounting position and an auxiliary sensor mounting position, and the optical axis of the main camera mounting position and the optical axis of the auxiliary sensor mounting position form a non-zero angle; a main support bracket, wherein the main support bracket is disposed inside the device housing and a vibration-damping connecting column is provided between the main support bracket and the device housing, and the main support bracket is mounted on the device housing through the vibration-damping connecting column. The device is mounted on a housing. A main control circuit board is mounted on the main support bracket. A heat-conducting bracket, L-shaped with one vertical side connected to the side of the main support bracket and the other side extending above the main control circuit board, is mounted on the heat-conducting bracket. The coprocessor board is attached to and fixed to the horizontal upper surface of the heat-conducting bracket and electrically connected to the main control circuit board via a vertically inserted board-to-board connector. Heat dissipation fins are mounted on the housing. A connecting base includes a connecting block fixedly mounted on the housing, the connecting block having a standard screw hole array and a dovetail groove.

[0005] Preferably, the vibration damping connecting column is made of rubber and has metal nuts at both ends, which are threaded to the device housing and the main support bracket, respectively.

[0006] Preferably, the thermally conductive bracket is made of aluminum alloy and has a thermally conductive silicone grease layer coated on the contact surface with the coprocessor board.

[0007] Preferably, the outer surface of the multispectral light-transmitting cover is provided with an anti-reflective film and a hydrophobic film in sequence.

[0008] Preferably, an infrared camera or a lidar is installed at the auxiliary sensor mounting position on the mounting plate.

[0009] Preferably, the device housing is provided with a cable integration interface, and the cable integration interface is a multi-core aviation plug.

[0010] Preferably, the heat-conducting bracket is further provided with a pressure strip spanning above the coprocessor board, and the two ends of the pressure strip are connected to the heat-conducting bracket by screws to press the coprocessor board tightly.

[0011] With the above structure, this utility model has the following advantages:

[0012] 1. By setting up a multispectral light-transmitting cover and mounting positions for main and auxiliary sensors with non-zero angles, this utility model can simultaneously or optionally integrate multiple sensors such as visible light, infrared, and lidar, realizing three-dimensional and multispectral perception of the environment, greatly expanding the application capabilities under complex lighting and weather conditions, and providing a rich data foundation for accurate analysis.

[0013] 2. The suspended installation structure, which isolates the main support frame from the device housing through vibration-damping connecting columns, effectively attenuates and absorbs vibrations and impacts from the moving platform, protecting the stable operation of core electronic components such as the main control circuit board and coprocessor. This not only ensures the quality of image acquisition but also extends the service life of the device.

[0014] 3. The L-shaped thermal bracket serves as both a structural component to fix the coprocessor board and a heat conduction path, efficiently transferring the heat generated by the coprocessor to the heat sink fins. Combined with the tight-fitting design of the thermal grease layer and pressure strip, it ensures efficient heat dissipation in a compact space, preventing the coprocessor from throttling due to overheating and ensuring the continuous high-performance operation of the intelligent analysis algorithm.

[0024] Combined with appendix Figures 1-4 A mobile platform video information acquisition and analysis device based on an intelligent operating system includes a device housing 1, a multispectral light-transmitting cover 2, a main support bracket 10, a heat-conducting bracket 12, heat dissipation fins 3, and a connecting base.

[0025] The multispectral light-transmitting cover 2 is located on one side of the device housing 1. The inner side of the multispectral light-transmitting cover 2 is provided with a mounting plate 8. The mounting plate 8 is provided with a main camera mounting position and an auxiliary sensor mounting position. The optical axis of the main camera mounting position and the optical axis of the auxiliary sensor mounting position form a non-zero angle, which ensures that the main camera, such as a high-definition visible light camera, and the auxiliary sensor can obtain information from different perspectives, which is convenient for subsequent data fusion and three-dimensional analysis.

[0026] The main support frame 10 is installed inside the device housing 1 and a vibration damping connecting column 9 is provided between it and the device housing 1. The vibration damping connecting column 9 enables the main support frame 10 to be installed on the device housing 1, so that the main support frame 10 and its core electronic components are elastically connected to the device housing 1, effectively isolating external vibration. The main support frame 10 is provided with a main control circuit board 11, which serves as the core of the device's operation and control, and is responsible for system scheduling, sensor driving, and preliminary data integration.

[0027] The heat-conducting bracket 12 is L-shaped, with one vertical side connected to the side of the main support bracket 10, and the other side extending above the main control circuit board 11. The heat-conducting bracket 12 is equipped with a coprocessor board 13, such as a GPU or NPU, which are high-performance computing units. The coprocessor board 13 is attached and fixed to the horizontal upper surface of the heat-conducting bracket 12, and the coprocessor board 13 is electrically connected to the main control circuit board 11 through a vertically inserted board-to-board connector. The vertical insertion method saves horizontal space, realizes short-distance, high-bandwidth data transmission, and improves signal integrity.

[0028] The heat dissipation fins 3 are disposed on the outer shell 1 of the device, and are integrally formed with the outer shell 1 or tightly attached by thermally conductive adhesive, so as to dissipate the internal heat to the surrounding air.

[0029] The connecting seat includes a connecting block 5 fixedly mounted on the outer shell 1 of the device. The connecting block 5 is provided with an array of standard screw holes 7 and a dovetail groove 6. The array of standard screw holes 7 is used to rigidly connect with the moving platform by bolts, while the dovetail groove 6 can cooperate with the matching slide rail to realize the quick disassembly and locking of the device, providing a flexible installation solution.

[0030] In one embodiment of this utility model, the vibration damping connecting column 9 is made of rubber and has metal nuts at both ends, which are threadedly connected to the device housing 1 and the main support bracket 10, respectively. Specifically, in conjunction with Figure 4 As shown, the rubber vibration damping connecting column 9 utilizes the high damping characteristics of rubber material to absorb and dissipate vibration energy. The metal nut provides a robust threaded connection interface to prevent the rubber parts from tearing, and also facilitates precise adjustment of the installation height and preload, ensuring the stable and reliable performance of the vibration damping system.

[0031] In one embodiment of this invention, the heat-conducting bracket 12 is made of aluminum alloy and has a thermally conductive silicone grease layer coated on its contact surface with the coprocessor board 13. Specifically, aluminum alloy has excellent thermal conductivity, which can quickly conduct the heat generated by the coprocessor board 13 away. The coated thermally conductive silicone grease layer is used to fill the microscopic gaps between the surface of the coprocessor board 13 and the heat-conducting bracket 12, eliminate air, significantly reduce contact thermal resistance, and thus improve the overall heat dissipation efficiency.

[0032] In one embodiment of this invention, an antireflective film and a hydrophobic film are sequentially provided on the outer surface of the multispectral light-transmitting cover 2. Specifically, the antireflective film reduces the reflection loss of specific wavelengths of light, such as visible light and infrared light, on the surface of the light-transmitting cover through the principle of optical interference, thereby increasing light transmittance and improving imaging quality. The outer hydrophobic film makes the surface of the light-transmitting cover hydrophobic, making it difficult for water droplets to adhere and causing them to roll off quickly. At the same time, it carries away dust, playing a self-cleaning role and ensuring that the sensor can still obtain a clear field of view in humid environments such as rain and fog.

[0033] In one embodiment of this utility model, an infrared camera or a lidar is installed at the auxiliary sensor mounting position on the mounting plate 8. Specifically, when an infrared camera is installed, the device has thermal imaging capabilities and can be used for nighttime reconnaissance, fire early warning, or equipment overheating detection; when a lidar is installed, the device can acquire high-precision three-dimensional point cloud data of the surrounding environment for obstacle avoidance, navigation, and 3D modeling. Users can flexibly select and configure the device according to actual application needs to achieve functional customization.

[0034] In one embodiment of this utility model, the device housing 1 is provided with a cable integration interface 4, and the cable integration interface 4 is a multi-core aviation plug. Specifically, as shown... Figure 2 As shown, this multi-core aviation connector integrates multiple cables such as power supply, video output, control signals, and data communication into one interface. It has a robust structure and good dustproof and waterproof performance, such as IP67 rating and tensile strength. It simplifies external wiring and improves the connection reliability of the system in harsh environments. This interface is usually located on the side and rear of the device housing 1, which facilitates centralized cable routing and management.

[0035] In one embodiment of this utility model, the heat-conducting bracket 12 is further provided with a pressure strip 14 spanning above the coprocessor board 13. Both ends of the pressure strip 14 are connected to the heat-conducting bracket 12 by screws, pressing the coprocessor board 13 firmly. Specifically, as shown... Figure 4 As shown, the pressure strip 14 applies pressure downward from the middle to ensure that the coprocessor board 13 and the surface of the heat-conducting bracket 12 are in uniform and tight contact, avoiding gaps caused by vibration or thermal expansion and contraction. At the same time, the auxiliary board maintains a stable connection with the board connector, further optimizing the stability of heat dissipation and electrical connection.

[0036] In summary, the working principle of this utility model device is as follows:

[0037] When the device is working, the main camera, such as a visible light camera, and the auxiliary sensors, such as an infrared camera or a lidar, first collect external environmental information synchronously through the multispectral light-transmitting cover 2. Since there is an angle between the optical axes of the two, data with parallax can be obtained, which is beneficial for three-dimensional information calculation. The collected raw data is transmitted to the main control circuit board 11.

[0038] After the main control circuit board 11 performs preliminary processing, such as image format conversion and data packaging, it transmits a large number of computing tasks, such as target recognition, image stitching, point cloud processing and other complex algorithms, to the coprocessor board 13 at high speed through the vertically plugged board-to-board connector. The coprocessor board 13 performs high-intensity computing as the computing power core and feeds back the analysis results to the main control circuit board 11. The main control circuit board 11 can output the results to the host computer or gimbal control system of the mobile platform through a multi-core aviation plug to realize decision-making and control.

[0039] Throughout the process, the vibration generated by the mobile platform is effectively isolated by the vibration damping connecting column 9, protecting the internal precision electronic components. At the same time, the large amount of heat generated by the coprocessor board 13 is efficiently transferred to the aluminum alloy thermal support 12 through the thermal grease layer, and then conducted through the device housing 1 to the external heat dissipation fins 3, and finally dissipated into the air, forming an efficient thermal management path to ensure the processor continues to operate at high performance.

[0040] The device is securely mounted on mobile platforms such as drones and robots via a standard screw hole array 7 or dovetail groove 6 on the connector, adapting to various mounting requirements. The anti-reflective and hydrophobic films ensure the data acquisition quality of the optical sensor in various environments.

[0041] This invention integrates features such as multispectral sensing, high-efficiency vibration reduction, active heat dissipation, and convenient installation, forming a high-performance and high-reliability video information acquisition and analysis system suitable for complex mobile platforms.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
