Description

Technical Field

[0001] This invention relates to the field of overhead crane technology, specifically to a comprehensive identification device for unattended overhead cranes. Background Technology

[0002] In the current field of industrial automation, overhead cranes (also known as bridge cranes) are widely used in warehouses, docks, factories, and other locations as important material handling equipment. With continuous technological advancements, unmanned overhead crane systems have gradually become a research hotspot, aiming to improve production efficiency, reduce labor costs, and enhance operational safety through automation and intelligent technologies. However, traditional unmanned overhead crane systems have many shortcomings in identification and positioning, such as low identification accuracy, inaccurate positioning, and poor adaptability to environmental changes. These problems severely restrict the widespread application and in-depth development of unmanned overhead crane systems.

In complex and ever-changing industrial environments, this fixed operating mode can easily lead to safety accidents such as collisions and positioning deviations, increasing maintenance costs and downtime. Furthermore, traditional overhead crane systems have significant limitations in identifying material type, location, and orientation, making it difficult to meet the demands of modern industry for high-precision, high-efficiency material handling.

A horizontal track 4 is fixedly connected to the top of the same side of each support column 1. Two horizontal tracks 4 are arranged parallel to each other. Two vertical tracks 5 are movably connected to the two horizontal tracks 4 via linear motors. The two vertical tracks 5 are arranged parallel to each other. A crane linear motor 8 is movably connected to the top of each of the two vertical tracks 5. An unmanned overhead crane 6 is fixedly connected to the top of the two crane linear motors 8. Motion sensors 17 are provided on the bottom of both sides of the unmanned overhead crane 6. An identification locator 11 is fixedly connected to the bottom of the unmanned overhead crane 6 on the side closer to the motion sensor 17. An industrial camera 12 is fixedly connected to the bottom of the unmanned overhead crane 6 on the side away from the identification locator 11. Multiple lateral locators 7 are uniformly embedded and fixedly connected to the ends of the multiple support columns 1 that are close to each other. The detection ends of the multiple lateral locators 7 are arranged correspondingly to each other. Multiple buried locators 2 are also uniformly arranged at the bottom between the multiple support columns 1 that are close to each other. The detection ends of the multiple buried locators 2 are all facing upwards.

[0036] Both sides of the top of the two overhead crane linear motors 8 are fixedly connected to lateral distance sensors 9, and the detection ends of the multiple lateral distance sensors 9 are all set towards the end away from the unattended overhead crane 6. Vertical distance sensors 10 are fixedly connected to the sidewalls of the two overhead crane linear motors 8 near the lateral distance sensors 9, and the detection ends of the multiple vertical distance sensors 10 are all set at points far apart from each other.

[0037] The unattended overhead crane 6 has an internal mounting cavity 18. A through-hole 13 is provided at the bottom of the unattended overhead crane 6, matching the position of the motion sensor 17. Motion stepper electric actuators 19 are provided on both sides of the internal mounting cavity 18. One end of each motion stepper electric actuator 19 is fixedly connected to a fixing flange 20. Both fixing flanges 20 are detachably connected to the interior of the internal mounting cavity 18. A telescopic rod 21 is movably connected to the output end of each motion stepper electric actuator 19.

[0038] Each of the two telescopic rods 21 has a connecting post 14 fixedly connected to one end of each other. Both connecting posts 14 are movably connected through the corresponding through holes 13. Both connecting posts 14 have a connecting plate 15 fixedly connected to their bottoms. Both motion sensors 17 have a connecting flange 16 fixedly connected to their tops. Both connecting flanges 16 are detachably connected to the corresponding connecting plates 15.

[0039] A signal box 3 is fixedly connected to one end of multiple support columns 1. A touch screen display 31 is embedded and fixedly connected to one end of the signal box 3. A control cavity 32 is opened in the inner wall of the signal box 3. A main control board 33 is fixedly connected to the inner wall of the control cavity 32. A communication chip 34 is fixedly connected to the inner wall of the control cavity 32 at one end of the main control board 33. A storage chip 35 is fixedly connected to the end of the control cavity 32 near the communication chip 34. A power management chip 36 is fixedly connected to the side wall of the control cavity 32 at the bottom of the main control board 33. A sensor chip 37 is fixedly connected to the end of the control cavity 32 near the power management chip 36.

[0040] A three-dimensional spatial coordinate system is established by multiple buried locators 2 and lateral locators 7. The position of the object is located by motion sensor 17, positioning recognition device 11 and industrial camera 12. At the same time, when the unattended overhead crane is moving, the horizontal distance sensor 9 and vertical distance sensor 10 are used to accurately locate the movement distance of the overhead crane, thereby improving the recognition and control effect.

[0041] Specifically: Buried locators 2 are evenly arranged at the bottom of multiple support columns 1 close to each other. These locators use high-precision radio frequency identification (RFID) or ultrasonic ranging technology to emit signals of a specific frequency and receive reflected signals to calculate the distance between the locator and the ground or the bottom of the object. Lateral locators 7 are evenly arranged on the sides of the support columns 1. These locators also use RFID or laser ranging technology to help determine the horizontal position of the object by measuring the distance to the side of the object.

[0042] By combining the underground locator 2 and the lateral locator 7, a three-dimensional spatial coordinate framework of the area where the object is located can be initially constructed.

[0043] Motion sensors 17, such as accelerometers and gyroscopes, are installed on the bottom of both sides of the unattended overhead crane 6 to monitor the crane's motion status (speed, acceleration, direction, etc.) in real time.

[0044] The positioning identifier 11 uses UWB (Ultra-Wideband) or Bluetooth positioning technology to further accurately determine the position of the item in three-dimensional space by measuring the distance and angle between it and a pre-installed tag on the item.

[0045] The data from the motion sensor 17 is combined with the measurement results from the positioning identifier 11 to dynamically adjust the estimated position of the item, ensuring the accuracy of the item's position during the movement of the unattended overhead crane 6.

[0046] An industrial camera 12 is fixedly connected to the side of the unmanned overhead crane 6 away from the positioning and recognition device 11. The camera is a high-definition, wide-angle camera, which is combined with advanced image processing algorithms (such as deep learning, object detection, etc.) to capture images of objects in real time.

[0047] By analyzing and processing the images, the type, shape, color, and other features of objects can be identified, further verifying and adjusting the object location information obtained through other sensors. The industrial camera 12 can also be used to monitor the environment around the unmanned overhead crane 6, ensuring operational safety.

[0048] Lateral distance sensors 9 are fixedly connected to both sides of the top of the two overhead crane linear motors 8. Using laser ranging or infrared ranging technology, they monitor the lateral distance between the unattended overhead crane 6 and the side support columns 1 or obstacles in real time. Vertical distance sensors 10 are fixedly connected to the side walls of the two overhead crane linear motors 8 near the lateral distance sensors 9. Similarly, using laser ranging or infrared ranging technology, they monitor the vertical distance between the unattended overhead crane 6 and the ground or obstacles above it in real time.

[0049] The horizontal distance sensor 9 and the vertical distance sensor 10 transmit the distance data they monitor in real time to the main control board 33. The main control board 33 calculates the feasible motion path of the unattended crane 6 in real time based on the preset safety threshold and motion planning algorithm.

[0050] During the movement of the unattended overhead crane 6, the main control board 33 dynamically adjusts the crane's speed and direction based on data from sensor feedback, ensuring the crane moves within a safe distance and avoiding collisions and positioning deviations. Simultaneously, the main control board 33 records the crane's trajectory and distance data, providing a basis for subsequent trajectory optimization and fault analysis.

[0051] By using multi-sensor fusion technology, the data from the buried locator 2, the lateral locator 7, the motion sensor 17, the positioning identifier 11, and the industrial camera 12 are comprehensively processed and analyzed, which can significantly improve the accuracy and reliability of object location positioning.

[0052] The real-time monitoring and feedback mechanism of the lateral distance sensor 9 and the vertical distance sensor 10 ensures the safety and stability of the unmanned crane 6 during its movement, and reduces collisions and downtime caused by positioning deviations.

[0053] Overall, this embodiment significantly improves the recognition and control performance of the unmanned overhead crane system through multi-sensor fusion and real-time feedback mechanisms, providing strong support for efficient and safe operation in modern industry.

[0054] The working principle of this invention is as follows: When this device identifies the operation of an unattended overhead crane, it captures material images in real time through an industrial camera 12, and analyzes the material type, location, and orientation through image processing algorithms. Simultaneously, the buried locator 2, the lateral locator 7, and the horizontal and vertical distance sensors monitor the spatial position of the overhead crane and materials in real time to ensure accurate positioning.

[0055] By integrating multiple environmental sensors, such as light sensors, temperature and humidity sensors, the system can detect environmental changes in real time, providing a basis for the dynamic adjustment of the overhead crane. (For example, in low-light conditions, it can automatically adjust camera parameters to improve image quality.) Based on the identification, positioning, and environmental perception results, the main control board 33, combined with the preset task, plans the optimal operating path. The linear motors of the overhead crane 8 and the vertical track 5 drive the overhead crane to move according to the planned path, achieving precise material handling. Remote communication is achieved through the communication chip 34, allowing operators to monitor the overhead crane's operating status in real time via mobile phones or computers, adjust operating parameters promptly, and perform fault diagnosis and maintenance. Simultaneously, the storage chip 35 stores operating data and fault records, providing a basis for subsequent optimization and improvement.
