Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an airport road foreign object detection device. This device solves the problem that existing devices mainly rely on cameras and ultrasonic radar for on-site foreign object detection, which has insufficient accuracy in identifying foreign objects that are similar in color to the road surface and have irregular shapes, and is prone to missed detection.

[0007] The above technical solution addresses the issue that when foreign objects, gaps, or potholes are present on the road, the pressure sensor data fluctuates, indicating the presence of such objects. This solves the problem that existing devices, which rely primarily on cameras and ultrasonic radar for on-site foreign object detection, lack sufficient accuracy in identifying foreign objects that are similar in color to the road surface and have irregular shapes, leading to missed detections.

[0008] Preferably, the control component includes a data processing module, a positioning module, a power management module, and a communication module. The data processing module, positioning module, power management module, and communication module are all located inside the vehicle body. The data processing module is electrically connected to the positioning module, power management module, communication module, walking mechanism, cylinder, and pressure sensor. The communication module is communicatively connected to the airport system. The power management module is electrically connected to the positioning module, communication module, cylinder, walking mechanism, and pressure sensor.

[0009] Preferably, the lower end of the spring is fixedly connected to a sliding plate, the outer wall of the sliding plate is slidably connected to the inside of the slide cylinder, the pressure sensor is disposed on the lower side of the sliding plate, and a through hole is provided on the lower side of the sliding plate.

[0010] Preferably, a displacement sensor is provided on the inner top wall of the slide cylinder, and the displacement sensor is electrically connected to both the data processing module and the power management module.

[0011] Preferably, the inner wall of the slide cylinder is provided with a slide groove, and the upper outer wall of the slide rod is fixedly connected to a slider, the outer wall of the slider being slidably connected to the inner wall of the slide groove.

[0012] Preferably, an extension plate is fixedly connected to the other side of the vehicle body, and an electromagnet is fixedly connected to the side of the extension plate away from the vehicle body. The electromagnet is electrically connected to both the data processing module and the power management module.

[0013] Preferably, a sweeping component and a cleaning component are provided on the lower side of the vehicle body, and the sweeping component and the cleaning component are arranged sequentially along the forward direction of the vehicle body. A storage box is provided inside the vehicle body, and the output end of the cleaning component is fixedly arranged on one side of the storage box. The data processing module and the power management module are both electrically connected to the sweeping component and the cleaning component.

[0014] Preferably, an observation window is provided on one side of the vehicle body, and the outer wall of the observation window passes through one side of the storage box.

[0015] Preferably, a second vision processing module is provided on one side of the vehicle body, and a first vision processing module is provided on the other side of the vehicle body. The data processing module and the power management module are both electrically connected to the first vision processing module and the second vision processing module.

[0016] Preferably, a turn signal and a taillight are provided on one side of the vehicle body, an obstacle avoidance module and a lighting module are provided on the other side of the vehicle body, and an audible and visual alarm module is provided on the upper side of the vehicle body. The data processing module and the power management module are both electrically connected to the turn signal, taillight, obstacle avoidance module, lighting module, and audible and visual alarm module.

[0017] Working principle: When using this device, the power management module supplies power to the device, and the data processing module acquires flight and aircraft take-off and landing time data from the airport system. This allows the data processing module to control the walking mechanism to move the vehicle body along the aircraft road according to a preset path without interfering with aircraft take-off and landing. During this process, the vision processing module identifies and detects foreign objects on the road in front of the vehicle body, and the electromagnet cleans up magnetic foreign objects on the road. Then, the cleaning component cleans the road and temporarily stores the cleaned garbage and foreign objects in the storage box, thereby realizing the function of foreign object identification and cleaning of the device. During the vehicle's movement, the rollers continuously contact the ground, exerting a certain force on it. This causes the sliding rod to slide upwards into the inner cavity of the cylinder, generating pressure in the pressure sensor and compressing the spring. When there are foreign objects, gaps, or potholes on the road, these objects or potholes cause the rollers to move upwards or downwards, resulting in changes in the pressure data from the pressure sensor. The data processing module uploads the location of the pressure change to the airport system, notifying relevant personnel for timely handling. During this process, a displacement sensor measures the distance the sliding rod travels in the cylinder in real time and transmits the signal to the data processing module for processing and analysis. This allows for the detection of the smoothness of the airport road surface and also assists in detecting the size of foreign objects, gaps, or potholes. This solves the problem that existing devices, which mainly rely on cameras and ultrasonic radar for on-site foreign object detection, have insufficient accuracy in identifying foreign objects that are similar in color to the road surface and have irregular shapes, leading to missed detections.

[0018] This invention provides a foreign object detection device for airport runways. It has the following beneficial effects: 1. This invention achieves vehicle movement through a walking mechanism. Through the cooperation of control components, cylinders, connecting plates, slides, slide rods, and springs, a certain pressure is created between the rollers and the ground. When there are foreign objects, gaps, or small potholes on the road, the pressure sensor data fluctuates. This solves the problem that existing devices mainly rely on cameras and ultrasonic radar for on-site foreign object detection, which has insufficient accuracy in identifying foreign objects that are similar in color to the road surface and have irregular shapes, and is prone to missed detection.

[0019] 2. This invention provides power to the positioning module, communication module, cylinder, walking mechanism, pressure sensor and data processing module through the power management module, and realizes the control function of the control components through the cooperation of the positioning module, data processing module and communication module.

[0020] 3. This invention powers the displacement sensor through a power management module, measures the sliding distance between the slide rod and the slide cylinder in real time through the displacement sensor, and transmits the signal to the data processing module for processing, analysis and comparison. In this way, the smoothness of the airport road can be judged through the data curve measured by the displacement sensor, thereby realizing the function of the device for detecting the life of the airport road.

[0021] 4. This invention supplies power to the electromagnet through a power management module and controls the power of the electromagnet through a data processing module, enabling the electromagnet to attract magnetic metals on airport roads, thereby realizing the function of the device in cleaning metal foreign objects.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 3 Appendix Figure 5 and attached Figure 7 This invention provides an airport road foreign object detection device, including a vehicle body 2, a walking mechanism 8 disposed on the lower side of the vehicle body 2, a control component disposed inside the vehicle body 2, a cylinder 19 disposed on one side of the vehicle body 2, a connecting plate 11 fixedly disposed at the output end of the cylinder 19, a plurality of sliding cylinders 14 fixedly connected to the lower side of the connecting plate 11, a sliding rod 13 slidably connected to the inner wall of the sliding cylinder 14, the lower outer wall of the sliding rod 13 passing through the lower side of the sliding cylinder 14, a spring 26 fixedly connected to the inner top wall of the sliding cylinder 14, a pressure sensor 28 disposed at the lower end of the spring 26, the lower side of the pressure sensor 28 disposed on the upper side of the sliding rod 13, a roller 12 rotatably connected to the lower side of the sliding rod 13, the plurality of rollers 12 being arranged linearly in two rows along the traveling direction of the vehicle body 2, the orthographic projection of the two rows of rollers 12 in the traveling direction of the vehicle body 2 forming a continuous coverage area, and without gaps in the width direction of the vehicle body 2, the control component being electrically connected to the walking mechanism 8, the cylinder 19, and the pressure sensor 28.

[0026] In this invention, the walking mechanism 8 is a driving device with a drive motor as the power source and tires as the walking wheels, used to drive the vehicle body 2 to move forward, backward, left, and right; the cylinder 19 can be a servo cylinder; the width of the roller 12 is less than 4 cm, and the movement trajectories formed by the front and rear rows of rollers 12 overlap during the movement of the vehicle body 2, so that the two rows of rollers 12 can completely cover the width of the vehicle body 2, avoiding the generation of blind spots.

[0027] When using this device, the control component controls the walking mechanism 8 to move the vehicle body 2 to the detection point on the aircraft road. The control component controls the drive of the output end of the cylinder 19, which drives the connecting plate 11 to move downward, causing the slide cylinder 14 to move downward and the roller 12 to contact the ground with a certain pressure. The reaction force of the ground on the roller 12 causes the slide rod 13 to slide upward inside the slide cylinder 14, thus compressing the spring 26. When using the device for the first time, the device first completes the full movement of the preset detection path on a flat aircraft road free of foreign objects. At this time, the control component records the initial pressure data between the spring 26 and the slide rod 13 through the pressure sensor 28 and generates a pressure curve, while also recording the extension length of the output end of the cylinder 19.

[0028] When using this device for foreign object detection, the vehicle body 2 is moving, and the pressure sensor 28 transmits data in real time to the control component for processing and analysis, and compares it with the initial data. When there is a foreign object on the road, the roller 12 will push the roller 12 upward as it rolls over the object, which in turn will drive the slide rod 13 upward, causing the pressure data between the slide rod 13 and the spring 26 to fluctuate. When there is a gap or small pothole in the road that is wider than 4 cm, the roller 12 will suddenly move downward under the action of the spring 26, causing the pressure between the slide rod 13 and the spring 26 to fluctuate. The control component marks the point at the position of the preset path and sends a cleaning notification to the background, thus realizing the function of the device in detecting foreign objects. This solves the problem that existing devices mainly rely on cameras and ultrasonic radar for on-site foreign object detection, which have insufficient recognition accuracy for foreign objects that are similar in color to the road surface and have irregular shapes, and are prone to missed detection.

[0029] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 7 The control components include a data processing module 20, a positioning module 21, a power management module 22, and a communication module 24. The data processing module 20, positioning module 21, power management module 22, and communication module 24 are all located inside the vehicle body 2. The data processing module 20 is electrically connected to the positioning module 21, power management module 22, communication module 24, walking mechanism 8, cylinder 19, and pressure sensor 28. The communication module 24 is connected to the airport system. The power management module 22 is electrically connected to the positioning module 21, communication module 24, cylinder 19, walking mechanism 8, and pressure sensor 28.

[0030] Specifically, the positioning module 21 is a positioning chip based on the BeiDou positioning system, the power management module 22 includes a lithium battery pack and a power management circuit, the data processing module 20 includes a chip and related circuits or uses a microprocessor, a single-chip microcomputer, etc., and the communication module 24 can use a 5G wireless communication module. All of the above are existing technologies.

[0031] The power management module 22 supplies power to the data processing module 20, positioning module 21, communication module 24, cylinder 19, and walking mechanism 8. During this process, the data processing module 20 monitors the power status of the power management module 22 in real time. When using the device, the communication module 24 obtains the flight and aircraft takeoff and landing times and statuses from the airport system and transmits the information to the data processing module 20 for processing and analysis. The data processing module 20 controls the walking mechanism 8 to start through a preset program, driving the vehicle body 2 onto the road to begin foreign object detection without interfering with aircraft takeoff and landing. The data processing module 20 controls the drive of the cylinder 19 output to extend a preset... The length of the roller 12 ensures contact with the ground and applies pressure. As the vehicle 2 moves, the pressure sensor 28 transmits the pressure data in real time to the data processing module 20 for processing and analysis, and compares it with the initial data. When pressure fluctuations occur and exceed the preset range, it indicates that there are foreign objects, gaps, or small potholes on the road. The data processing module 20 marks the location of this point on the path through the positioning module 21 and uploads it to the airport system through the communication module 24 to notify relevant personnel to check and clean it. This not only achieves the foreign object detection function of the device, but also avoids interference with aircraft takeoff and landing, thus improving the efficiency of foreign object detection.

[0032] Please see the appendix Figure 5 The lower end of the spring 26 is fixedly connected to the slide plate 27. The outer wall of the slide plate 27 is slidably connected to the inside of the slide cylinder 14. The pressure sensor 28 is set on the lower side of the slide plate 27, and a through hole is opened on the lower side of the slide plate 27.

[0033] Specifically, the pressure sensor 28 is supported by the slide plate 27, and the slide plate 27 and the slide cylinder 14 are connected by sliding up and down, which helps to improve the accuracy of the pressure sensor 28.

[0034] Please see the appendix Figure 5 and attached Figure 7 A displacement sensor 25 is installed on the inner top wall of the slide cylinder 14. The displacement sensor 25 is electrically connected to the data processing module 20 and the power management module 22.

[0035] Specifically, the displacement sensor 25 is a laser displacement sensor. The laser of the displacement sensor 25 passes through the through holes on the upper and lower sides of the slide plate 27 and does not interfere with the pressure sensor 28. The power management module 22 supplies power to the displacement sensor 25, and the displacement sensor 25 monitors its position relative to the slide bar 13 in real time and transmits it to the data processing module 20 for processing and analysis. By comparing the data with the initial data, the height of the foreign object or the depth of the gap or pit can be obtained. At the same time, within the normal range of pressure fluctuation between the slide bar 13 and the slide plate 27, the smoothness of the airport road can be judged by the data curve measured by the displacement sensor 25, and the lifespan of the airport road can be predicted in advance, thus realizing the function of the device for detecting the lifespan of the airport road.

[0036] Please see the appendix Figure 6 The inner wall of the slide cylinder 14 is provided with a slide groove 30, and the upper outer wall of the slide rod 13 is fixedly connected to a slider 29, and the outer wall of the slider 29 is slidably connected to the inner wall of the slide groove 30.

[0037] Specifically, by sliding the slide groove 30 and the slider 29 up and down, the sliding of the slide rod 13 in the slide cylinder 14 is limited, preventing the slide rod 13 from sliding out of the slide cylinder 14, and at the same time, the rolling direction of the vehicle body 2 is limited.

[0038] Please see the appendix Figure 1 and attached Figure 7 An extension plate 6 is fixedly connected to the other side of the vehicle body 2. An electromagnet 7 is fixedly connected to the side of the extension plate 6 away from the vehicle body 2. The electromagnet 7 is electrically connected to the data processing module 20 and the power management module 22.

[0039] Specifically, the power management module 22 supplies power to the electromagnet 7, the length of which is the width of the vehicle body 2 in the direction of travel. The data processing module 20 controls the power of the electromagnet 7, enabling it to attract magnetic metals on the airport road, thus realizing the device's function of cleaning metal foreign objects.

[0040] Please see the appendix Figure 4 and attached Figure 7 The sweeping component 9 and the cleaning component 10 are arranged on the lower side of the vehicle body 2. The sweeping component 9 and the cleaning component 10 are arranged sequentially along the forward direction of the vehicle body 2. The storage box 23 is arranged inside the vehicle body 2. The output end of the cleaning component 10 is fixedly arranged on one side of the storage box 23. The data processing module 20 and the power management module 22 are both electrically connected to the sweeping component 9 and the cleaning component 10.

[0041] Specifically, the sweeping component 9 includes a motor-driven rotating sweeping brush, and the cleaning component 10 includes a motor-driven roller brush and a negative pressure machine for creating negative pressure to extract garbage. These are all existing technologies. When the vehicle body 2 moves along a preset path, the power management module 22 supplies power to the sweeping component 9 and the cleaning component 10. The data processing module 20 controls the sweeping component 9 to sweep garbage and foreign objects towards the lower center of the vehicle body 2. Then, with the cooperation of the cleaning component 10, the garbage and foreign objects are cleaned and temporarily stored in the storage box 23, thereby realizing the function of the device in cleaning foreign objects.

[0042] Please see the appendix Figure 3 and attached Figure 4 An observation window 15 is provided on one side of the vehicle body 2, and the outer wall of the observation window 15 passes through one side of the storage box 23.

[0043] Specifically, the observation window 15 is transparent and can be made of materials such as glass or acrylic sheet. Through the observation window 15, the amount of waste inside the storage box 23 can be observed, which makes it easier for staff to clean it in a timely manner, thereby improving the ease of use of the device.

[0044] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 7 A vision processing module 218 is provided on one side of the vehicle body 2, and a vision processing module 4 is provided on the other side of the vehicle body 2. The data processing module 20 and the power management module 22 are both electrically connected to the vision processing module 4 and the vision processing module 218.

[0045] Specifically, both vision processing module 2 (18) and vision processing module 1 (4) are camera groups, based on image processing and recognition technology, to perform image recognition and detection of foreign objects on the aircraft road, which is existing technology. During the movement of vehicle body 2, power is supplied to vision processing module 1 (4) and vision processing module 2 (18) through power management module 22. Vision processing module 1 (4) monitors the road in the direction of vehicle body 2's movement in real time and transmits the data to data processing module 20 for processing and analysis to determine whether there are foreign objects. When a foreign object is detected, data processing module 20 marks the location. When vehicle body 2 moves to that location, the power of sweeping component 9 and cleaning component 10 is increased to clean the foreign object. If the foreign object is not cleaned, it will be rolled over by roller 12. Combined with the image recognition of vision processing module 2 (18) at the rear of vehicle body 2, the detection of foreign objects is further improved. The information is transmitted to the airport system through communication module 24 to remind relevant personnel to handle it in time. During this process, vision processing module 2 (18) can verify the cleaning effect and location of foreign objects, thereby helping to improve the detection and cleaning effect of foreign objects by the device.

[0046] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 7 One side of the vehicle body 2 is equipped with a turn signal 16 and a taillight 17, and the other side of the vehicle body 2 is equipped with an obstacle avoidance module 3 and a lighting module 5. The upper side of the vehicle body 2 is equipped with an audible and visual alarm module 1. The data processing module 20 and the power management module 22 are electrically connected to the turn signal 16, the taillight 17, the obstacle avoidance module 3, the lighting module 5, and the audible and visual alarm module 1.

[0047] Specifically, the obstacle avoidance module 3 is composed of a lidar. The power management module 22 supplies power to the turn signal 16, taillight 17, obstacle avoidance module 3, lighting module 5, and audible and visual alarm module 1. When the vehicle body 2 is moving, the obstacle avoidance module 3 realizes the obstacle avoidance function of the device. Through the cooperation of the turn signal 16, taillight 17, lighting module 5 and audible and visual alarm module 1, the device provides audible and visual reminders during operation.
