[0022] Currently, due to their inherent fragility, limited scope, and unreliability, single-sensor systems are typically only suitable for scenarios with fixed conditions and simple tasks, such as vehicle recording. However, in the face of the open, dynamic, and uncertain complex environments of the real world, relying solely on a single sensor is far from sufficient to meet the stable operation requirements of intelligent systems with extremely high safety requirements, such as autonomous vehicles and intelligent agricultural machinery.

[0023] To address the aforementioned problems, embodiments of this utility model propose a multi-sensor fusion device. The specific structure and function of the multi-sensor fusion device provided by embodiments of this utility model will be described below with reference to text and accompanying drawings.

[0024] Reference Figure 1 and Figure 2 The multi-sensor fusion device provided according to an embodiment of this utility model includes: a housing 100, an image sensing module 200, a transceiver detection module 300, a sound-emitting module 400, and a control module. The housing 100 is generally rectangular in shape and has an internal cavity. The image sensing module 200 is installed in the internal cavity of the housing 100 and exposed on the front sidewall of the housing 100, used to capture visual information of a large area around the device in real time, providing image data for subsequent data processing and analysis by the control module. The transceiver detection module 300 is disposed in the internal cavity and exposed on the front sidewall of the housing 100, located on one side of the image sensing module 200, used to measure information such as the distance and speed of surrounding objects. The sound-emitting module 400 is installed in the internal cavity and exposed on the front sidewall of the housing 100, used to emit an alarm sound. The control module is disposed in the internal cavity and electrically connected to the image sensing module 200, the transceiver detection module 300, and the sound-emitting module 400. The control module possesses data processing capabilities and logic control functions. It can receive data from the image sensing module 200 and the transceiver detection module 300 in real time and perform rapid analysis and processing. Based on the processing results, the control module sends control commands to the sound-emitting module 400, causing it to emit corresponding alarm sounds.

[0025] In practical applications, when multi-sensor fusion devices are used in scenarios such as autonomous vehicles and intelligent agricultural machinery, the image sensing module 200 continuously captures images of the area in front of the vehicle, while the transceiver detection module 300 measures the distance and speed of vehicles and obstacles ahead in real time. The control module comprehensively analyzes this data, and if it determines that there is a collision risk ahead, it immediately controls the sound module 400 to issue an alarm to alert the driver. Simultaneously, the control module can also send relevant information to the vehicle's braking and steering systems to enable automatic emergency braking or avoidance maneuvers, effectively improving the safety and reliability of autonomous vehicles.

[0026] Reference Figure 3 Optionally, the rear sidewall of the housing 100 is provided with multiple screw holes 150, such as four M8 screw holes, to facilitate the installation of the housing 100 in vibrating environments such as vehicles, cabinets, or robotic arms.

[0027] Reference Figure 1 and Figure 2 According to the multi-sensor fusion device provided in the embodiments of the present invention, the image sensing module 200 is at least one of a monocular camera sensor 210, a binocular camera sensor 220, and a multispectral camera sensor 230.

[0028] Using a monocular camera sensor 210 as the image sensing module 200 offers advantages such as lower cost and easier installation. The monocular camera sensor 210 captures images through a single lens and analyzes and processes these images using image processing algorithms, enabling it to identify information such as objects, shapes, and colors in the environment.

[0029] When using a binocular camera sensor 220, which has two cameras, it acquires depth information of objects by simulating the parallax principle of human eyes. Compared to a monocular camera sensor 210, the binocular camera sensor 220 can more accurately measure the distance between objects and devices, improving the accuracy of environmental perception. In the field of autonomous vehicles, the binocular camera sensor 220 can detect the distance to vehicles, pedestrians, and other obstacles ahead, providing more reliable data support for obstacle avoidance and path planning. Simultaneously, the binocular camera sensor 220 also enhances the perception of three-dimensional space, better recognizing the shape and posture of objects, making it suitable for applications with high spatial information requirements.

[0030] When a multispectral camera sensor 230 is used, it can capture spectral information in different bands, including not only visible light but also infrared, ultraviolet, and other bands of light. This gives the multispectral camera sensor 230 a stronger ability to adapt to complex environments. For example, at night or in low-light conditions, the infrared band can help the sensor capture objects invisible to the human eye; in agriculture, the multispectral camera sensor 230 can analyze the different spectral information reflected by plants to detect plant health status, pest and disease conditions, etc. The multispectral camera sensor 230 can provide richer and more comprehensive environmental information, providing more dimensions of data support for the decision-making of intelligent systems.

[0031] In practical applications, these three sensors can also be combined. For example, a monocular camera sensor 210 can be used in conjunction with a binocular camera sensor 220. The monocular camera sensor 210 can quickly capture large-area environmental images, providing macroscopic environmental information; while the binocular camera sensor 220 can perform depth measurements on specific areas. The two complement each other, ensuring both the efficiency of environmental perception and improving measurement accuracy. This combination is suitable for applications requiring both a certain range and accuracy of environmental perception, such as navigation and environmental modeling for intelligent robots.

[0032] Another approach is to combine the binocular camera sensor 220 with the multispectral camera sensor 230. The binocular camera sensor 220 provides distance and three-dimensional spatial information of the object, while the multispectral camera sensor 230 provides spectral feature information of the object.

[0033] Alternatively, a monocular camera sensor 210, a binocular camera sensor 220, and a multispectral camera sensor 230 can be integrated simultaneously in a multi-sensor fusion device. The monocular camera sensor 210 is responsible for quickly acquiring environmental images, the binocular camera sensor 220 provides accurate depth and spatial information, and the multispectral camera sensor 230 supplements spectral feature information. This comprehensive combination can adapt to various complex environmental conditions, whether day or night, indoors or outdoors, providing accurate and comprehensive environmental perception data for intelligent systems, greatly improving the reliability and adaptability of the system, and can be widely used in many fields such as autonomous driving, intelligent security, and industrial inspection.

[0034] Optionally, a high-transmittance explosion-proof lens can be installed on the front side of the housing 100, through which the graphic sensing module 200 can acquire external information. A silicone sealing ring can be installed at the connection between the explosion-proof lens and the housing 100 to ensure the airtightness of the connection between the housing 100 and the explosion-proof lens, thereby achieving dustproof and waterproof effects.

[0035] Reference Figure 1 and Figure 2 According to the multi-sensor fusion device provided in this embodiment of the present invention, the transceiver detection module 300 includes a lidar sensor 310, and an opening is provided on the front side of the housing 100. The size of the opening matches the shape of the lidar sensor 310, ensuring that the sensor can be securely installed therein and reliably connected to the internal wiring of the housing 100. By placing the lidar sensor 310 on the front side of the housing 100, the lidar sensor 310 is not obstructed by other components of the housing 100 when emitting and receiving laser signals, ensuring smooth signal transmission. The lidar sensor 310 accurately calculates the distance between the object and the sensor by emitting a laser beam into the surrounding environment and measuring the time from emission to reflection from the object. Because it is exposed on the front side of the housing 100, the lidar sensor 310 can perform omnidirectional and high-precision scanning of the area in front of the device. In autonomous vehicle applications, when the car is moving, the lidar sensor 310 exposed on the front side of the housing 100 can detect the distance, shape, and position information of vehicles, pedestrians, obstacles, etc. on the road ahead in real time and quickly. Its scanning range is extensive, covering a large area in front of the car, providing timely and accurate environmental data for the car's autonomous driving system, helping the system make correct decisions, such as obstacle avoidance, following other vehicles, and overtaking.

[0036] Furthermore, the design of the lidar sensor 310 being exposed on the front side of the housing 100 facilitates maintenance and repair. When the sensor malfunctions or requires cleaning, technicians can operate it directly from the front of the housing 100 without disassembling the entire device, greatly saving maintenance time and costs.

[0037] Optionally, the transceiver detection module 300 may also include infrared light transceiver sensors, etc., which can be selected according to actual needs.

[0038] According to the multi-sensor fusion device provided in the embodiments of this utility model, the control module includes a controller and at least one of an AI computing chip, a communication chip, and a positioning chip.

[0039] When the control module consists only of a controller, the controller possesses basic logic control and data processing capabilities, enabling preliminary analysis and processing of data transmitted from the image sensing module 200 and the transceiver detection module 300. For example, in simple environmental monitoring scenarios, the image sensing module 200 acquires environmental images, and the transceiver detection module 300 obtains distance information of surrounding objects. The controller can perform simple classification and judgment on this data according to preset rules, such as determining whether an object has entered a specific area, and control the sound-emitting module 400 to emit corresponding prompts. This combination method is simple in structure and low in cost, making it suitable for application scenarios with low functional requirements and limited budgets.

[0040] If the control module is composed of a controller and an AI computing chip, the intelligence level of the device will be greatly improved. The controller is responsible for the overall system coordination and basic control, while the AI ​​computing chip focuses on the in-depth analysis and processing of complex data. Taking an autonomous vehicle as an example, the image sensing module 200 and the transceiver detection module 300 collect massive amounts of environmental data, including road conditions, traffic signs, and the dynamics of other vehicles and pedestrians. The AI ​​computing chip can use deep learning algorithms to quickly analyze and understand this data, identify the categories and behavioral patterns of various objects, and predict their future trajectories. Based on the analysis results of the AI ​​computing chip, the controller makes more accurate decisions, such as adjusting the vehicle's speed, direction, and braking, thereby improving the safety and reliability of autonomous driving.

[0041] When the control module employs a combination of a controller and a communication chip, the communication capabilities of the multi-sensor fusion device are enhanced. The controller performs routine control of each module, while the communication chip is responsible for data transmission between the device and external equipment or systems.

[0042] If the control module consists of a controller and a positioning chip, it can provide the device with precise location information. The positioning chip can be a GPS, BeiDou, or other global positioning system chip, or a chip based on indoor positioning technology. In intelligent agricultural machinery applications, multi-sensor fusion devices installed on agricultural machinery can accurately obtain the real-time location information of the machinery through the positioning chip. The controller, based on the positioning information and data from the image sensing module 200 and the transceiver detection module 300, achieves precise navigation and operation control of the agricultural machinery. For example, during sowing operations, the controller can control the machinery to sow according to a predetermined route and spacing based on the positioning information, improving the accuracy and uniformity of sowing.

[0043] When a control module integrates a controller, AI computing chip, communication chip, and positioning chip, the controller coordinates the operation of each chip, the AI ​​computing chip performs in-depth analysis of complex data, the communication chip enables efficient communication with the outside world, and the positioning chip provides accurate location information. In smart city traffic management, multi-sensor fusion devices are installed on traffic lights or monitoring equipment. The image sensing module 200 and the transceiver detection module 300 collect information such as traffic flow and vehicle speed; the AI ​​computing chip analyzes traffic conditions and predicts congestion trends; the positioning chip determines the location of the equipment; and the communication chip transmits all data to the traffic management center. Based on this information, the traffic management center adjusts the duration of traffic lights in real time, optimizes traffic flow, and improves the efficiency and safety of urban traffic.

[0044] Reference Figure 1 and Figure 2 According to the multi-sensor fusion device provided in this embodiment of the present invention, the sound-emitting module 400 includes two speakers 410, which are respectively placed on the left and right sides of the front of the housing 100. When the image sensing module 200 and the transceiver detection module 300 detect an abnormality, the control module controls the sound-emitting module 400 to emit a sound. Since the speakers 410 are in relative positions, the sound can propagate in different directions, avoiding the sound field dead zones that may occur when a single speaker 410 emits a sound, so that the alarm sound can more comprehensively cover the surrounding environment and attract people's attention in a timely manner.

[0045] Optionally, a waterproof and sound-permeable membrane is provided at the junction of the housing 100 and the speaker 410, which can achieve sound transmission while also being waterproof and dustproof.

[0046] Optionally, the sound module 400 can also use a buzzer, which is small in size and low in cost. In some simple application scenarios where the requirements for sound quality and complexity are not high, such as during the operation of intelligent agricultural machinery, the buzzer can emit a relatively sharp sound, which can effectively attract the attention of personnel.

[0047] Reference Figure 3According to the multi-sensor fusion device provided in this embodiment of the present invention, a plurality of heat dissipation fins 110 are provided on the rear side of the housing 100. The plurality of heat dissipation fins 110 are arranged at intervals, and the interval between adjacent heat dissipation fins 110 can ensure smooth airflow between the fins, forming an effective convection heat dissipation channel. When the internal components of the device operate, heat is generated, which is conducted to the housing 100 and dissipated through the heat dissipation fins 110. Since the heat dissipation fins 110 have a large contact area with the air, the heat dissipation efficiency can be improved. For example, in intelligent monitoring equipment that operates for a long time in a high-temperature environment, the multi-sensor fusion device works continuously, and the internal electronic components generate heat. The spaced heat dissipation fins 110 can dissipate the heat in time, ensuring that the device can operate stably even at high temperatures.

[0048] Optionally, the housing 100 is made of aluminum alloy, which is a good conductor of heat with a high thermal conductivity. The multi-sensor fusion device generates a large amount of heat during operation, and the aluminum alloy housing 100 can quickly conduct the heat generated by the internal components to the surface of the housing 100, and dissipate it into the surrounding environment through the heat dissipation fins 110. This effectively maintains a stable internal temperature, preventing heat accumulation within the housing 100's interior and ensuring that the components inside remain within a suitable operating temperature range, reducing performance fluctuations and the risk of damage due to excessive temperature.

[0049] It should be noted that the outer shell 100 is formed by die casting, which gives the outer shell 100 a certain rigidity, effectively resisting the impact and extrusion of external forces, preventing the outer shell 100 from deforming, and thus providing reliable protection for the components in the inner cavity, ensuring that the device can work normally in various complex environments.

[0050] Reference Figure 3 According to the multi-sensor fusion device provided in the embodiment of this utility model, the side wall of the outer shell 100 is provided with a vent hole that communicates with the inner cavity, and a vent valve 120 is provided at the vent hole. The vent valve 120 can balance the pressure between the inner cavity of the outer shell 100 and the outside.

[0051] During operation, the components inside the multi-sensor fusion device generate heat, causing the air inside the cavity to expand and the pressure to rise. The vent valve 120 allows the expanded air to be released in a timely manner, maintaining stable pressure within the internal network. When the multi-sensor fusion device stops operating and the temperature drops, the air inside the inner wall contracts, creating negative pressure. The vent valve 120 then allows external air to be introduced, preventing the outer casing 100 from deforming due to the negative pressure.

[0052] It should be noted that when the multi-sensor fusion device is installed inside the machine housing, the internal pressure of the machine housing may change due to various factors during operation. At this time, the vent valve 120 can adjust the air pressure inside the outer shell 100 according to the change in external air pressure, thereby preventing the outer shell 100 from rupturing due to overpressure or being sucked down due to negative pressure.

[0053] It should be noted that the breathable valve 120 also achieves a unique waterproof and breathable function. Its interior uses a special waterproof and breathable membrane material with numerous tiny pores. The size of these pores is precisely designed to allow air molecules to pass freely, thereby achieving gas exchange and pressure balance. However, water molecules, due to their larger diameter, cannot pass through these tiny pores, thus effectively preventing moisture from entering the device's internal cavity. For example, in multi-sensor fusion devices used outdoors, which may encounter harsh weather conditions such as rain and humidity, the waterproof and breathable function of the breathable valve 120 ensures that the device's interior is not corroded by moisture.

[0054] Reference Figures 1 to 3 According to the multi-sensor fusion device provided in the embodiment of the present utility model, the housing 100 has a top and a bottom opposite each other, and the top of the housing 100 is provided with a brim 130, which extends toward the front side of the housing 100.

[0055] When it rains, the forward-extending brim 130 can effectively block rainwater, preventing the graphics sensing module 200, transceiver detection module 300 and sound module 400 exposed on the front of the housing 100 from being directly washed away by rainwater, ensuring that the multi-sensor fusion device can work normally and stably in rainy weather.

[0056] When encountering strong sunlight, the brim 130 can effectively block the sunlight, preventing the graphic sensor module 200 from being directly exposed to sunlight and affecting its normal use.

[0057] Understandably, by blocking sunlight with the brim 130, the area of ​​the front of the outer shell 100 directly exposed to sunlight can be reduced. This helps maintain a relatively stable temperature environment for the outer shell 100 and its internal cavity, avoids various problems caused by excessive temperature, and ensures that the multi-sensor fusion device can operate reliably for a long time.

[0058] It should be noted that the brim 130 can also, to some extent, prevent dust in the air from falling directly onto the front of the outer shell 100, reducing dust accumulation.

[0059] Reference Figures 1 to 3According to the multi-sensor fusion device provided in this utility model embodiment, the brim 130 can be rotatably connected to the outer shell 100 by screws. In use, the position of the brim 130 in the front and back directions can be adjusted according to the actual rainfall angle or the angle of sunlight, which can ensure that it can still work normally in bad weather.

[0060] Reference Figure 3 According to the multi-sensor fusion device provided in this utility model embodiment, the control module further includes at least two wire harness interfaces 140. The at least two wire harness interfaces 140 are arranged at intervals and exposed on the side wall of the housing 100. Specifically, multiple wire harness interfaces 140 are arranged below the rear side wall of the housing 100. The multiple wire harness interfaces 140 include power interfaces, USB interfaces, Ethernet interfaces, etc., which can be set according to actual needs.

[0061] The inclusion of multiple harness interfaces 140 enhances the scalability and compatibility of the multi-sensor fusion device. Users can flexibly add or replace connected devices according to their actual needs without requiring large-scale modifications to the device.

[0062] Optionally, the number of wire harness interfaces 140 can be 2, 3, 4, etc., which can be set according to actual needs.

[0063] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
