Description

Technical Field

[0001] This invention belongs to the field of aircraft assembly technology, and relates to an intelligent risk warning device for assembly and manufacturing sites and its usage method. Background Technology

[0002] With the rapid development of the aviation industry, the requirements for production efficiency, product quality, and safety in the aviation manufacturing sector are constantly increasing. At the same time, ensuring the safety of operators is paramount. To guarantee personnel safety, operators are required to wear work clothes and helmets in the workshop, and in some situations, safety goggles are also required. Currently, the main method relies on inspection personnel conducting unscheduled inspections to ensure operators are dressed as required. Various inspection methods exist, including scheduled inspections, fixed-point inspections, and random checks. However, this traditional inspection method has many limitations. It is constrained by personnel's physical strength, energy, and attention, making it difficult to achieve 24 / 7, all-round monitoring, which to some extent affects the efficiency and quality of inspections. Furthermore, manual inspection also suffers from low efficiency, high costs, and significant safety hazards. Summary of the Invention

[0003] This invention proposes an intelligent risk alarm device and its usage method for assembly manufacturing sites. By utilizing machine vision technology, it enables real-time monitoring and analysis of assembly site data, achieving comprehensive monitoring of the production site, promptly detecting situations where operators are not dressed or wearing safety equipment as required, providing immediate warnings, and preventing production accidents.

[0004] The technical solution adopted in this invention is as follows:

[0005] A smart alert device for risk warning at an assembly manufacturing site includes mechanical components, a detection and control component, and a hydraulic control system. The mechanical components include a support frame erected at the assembly site and a hydraulic actuation mechanism. The detection and control component controls the hydraulic actuation mechanism through the hydraulic control system, enabling the smart camera 15 in the detection and control component to move along the support frame to achieve all-round video acquisition and personnel tracking. The acquired data is processed and analyzed to form control commands, which are then controlled by the hydraulic control system to control the hydraulic actuation mechanism.

[0006] The mechanical component structure includes a frame 7, a hydraulic actuator 8, an actuator rod 9, a work frame 10, a pressure plate 11, a movable support block 13, and a camera adjustment mechanism 14. The frame 7 includes four columns, installed on the periphery of the monitoring range at the assembly site. A connecting rod is fixedly connected between the tops of the four columns to form a rectangular frame for support. The work frame 10 is an X-shaped slide rail, fixedly installed within the rectangular frame at the top of the frame 7. The pressure plate 11 and the movable support block 13 are respectively positioned above and below the work frame 10. A connecting shaft at the bottom center of the pressure plate 11 passes through the work frame 10 and is fixedly connected to the movable support block 13, allowing the pressure plate 11 and the movable support block 13 to move together along the work frame 10. A vertical shaft is set at the top center of the plate 11, and a camera adjustment mechanism 14 is installed at the bottom of the movable support block 13. The camera adjustment mechanism 14 is connected to the smart camera 15 and is used to adjust the angle of the smart camera 15. There are two hydraulic actuators 8, which are rotatably connected to the top of two diagonally distributed columns in the frame 7. Two actuator rods 9 are respectively engaged with the two hydraulic actuators 8. The ends of the two actuators are made of lugs and are rotatably connected to the vertical shaft at the top of the pressure plate 11. By coordinating the extension and retraction of the two actuator rods 9, the pressure plate 11 and the movable support block 13 are driven to move along the work frame 10, thereby enabling the smart camera 15 to move to any position on the work frame 10 and realize all-round monitoring of the assembly site.

[0007] The detection and control components include an emergency stop button 1, a voice warning device 2, an alarm clearing button 3, a control cabinet 4, control buttons 5, a display screen 6, a smart camera 15, a microcontroller 16, and a controller 17. The control cabinet 4 serves as the support structure for the detection and control components. The emergency stop button 1, voice warning device 2, alarm clearing button 3, control buttons 5, and display screen 6 are located outside the control cabinet 4, while the microcontroller 16 and controller 17 are located inside. The smart camera 15 is fixed to a camera adjustment mechanism 14. By adjusting the position of the smart camera 15, it tracks personnel in the assembly area and collects omnidirectional video data, which is then transmitted to the microcontroller 16. The microcontroller 16 is equipped with an intelligent recognition system that can process the video data collected by the smart camera 15. The system identifies risks to personnel and generates control commands based on the results, which are then sent to the controller 17. The controller 17 drives the hydraulic actuator 8 and the camera adjustment mechanism 14 to perform corresponding actions to adjust the position and shooting angle of the intelligent camera 15. Simultaneously, it controls the alarm 2 to issue an alarm to provide risk warnings. The emergency stop button 1 is located on the side of the control cabinet 4 and serves as an emergency operation component. When a safety risk occurs at the assembly site, pressing the emergency stop button 1 will cut off the power to the device. The voice alarm 2 is controlled by the controller 17. After identifying a risk, it will emit a flashing red light to warn of the danger or potential hazard. The alarm clearing button 3 is used to stop the alarm 2 from working. The control buttons 5 include four buttons, which are used for powering on, detecting, recording, and clearing the device, respectively.

[0008] The hydraulic control system includes an electromagnetic directional valve 12, a hydraulic oil tank 18, a relief valve 19, a hydraulic pump 20, a safety valve 21, and a filter 22, all installed inside the control cabinet 4. The hydraulic oil tank 18 stores hydraulic oil. The hydraulic pump 20 is connected to the oil outlet of the hydraulic oil tank 18. A relief valve 19 is installed on the oil line between the two to allow the hydraulic oil to flow back to the hydraulic oil tank 18 when excessive pressure causes overflow. Downstream of the hydraulic pump 20, two oil lines are connected to two hydraulic actuators 8, respectively. Both oil lines are equipped with a safety valve 21 and an electromagnetic directional valve 12. The safety valve 21 limits the pressure in its respective pipeline, protecting the hydraulic system. The two electromagnetic directional valves 12 control the extension or retraction of the two hydraulic actuators 8, respectively. The oil outlets of both hydraulic actuators 8 connect to the return port of the hydraulic oil tank 18. A filter 22 is installed before the return port to prevent contaminated oil from flowing into the hydraulic system and damaging hydraulic components.

[0009] A method for using an intelligent risk alarm reminder device for assembly manufacturing sites includes the following steps:

[0010] Step 1: Before use, perform a visual inspection of the device to ensure that the labels are complete and the appearance is intact.

[0011] Step 2: Press the power button in control button 5. The display screen 6 will display normally, the hydraulic pump 20 will start, and the smart camera 15 will start.

[0012] Step 3: Test emergency stop button 1. The operator enters the assembly site and presses the test button in control button 5. At this time, the smart camera 15 moves with the operator. Pressing emergency stop button 1 will stop the smart camera 15 from moving with the operator.

[0013] Step 4: Press the detection button in control button 5 to activate the on-site personnel risk alarm; the intelligent camera 15 collects image and video data of all personnel on-site from all directions, transmits it to the microcontroller 16 for risk identification, and generates control commands to send to the controller 17. The controller 17 controls the two electromagnetic reversing valves 12 to achieve coordinated adjustment of the extension and retraction lengths of the two hydraulic actuators 8, thereby adjusting the position of the intelligent camera; when a personnel risk is identified, the microcontroller 16 sends a command to the controller 17, and the controller 17 controls the voice alarm 2 to issue an alarm according to the command. After the risk is eliminated, press the alarm clearing button 3 to clear the alarm.

[0014] Step 6: After completing the risk alarm work, press the record button on control button 5 to record the risk alarm work for the current shift for future reference. If you need to delete the record, press the clear button on control button 5 to clear the record.

[0015] Step 7: After all risk alarms have been activated, press the power button in control button 5 to power off the entire device.

[0016] The beneficial effects of this invention are:

[0017] This invention features a timely feedback mechanism for rapid response and necessary preventative measures, effectively preventing safety accidents. Its automation and intelligence significantly reduce the time and cost of manual inspections, are unaffected by subjective human judgment, and provide comprehensive real-time monitoring of the assembly site. This allows for accurate identification of potential problems, enabling targeted adjustments and optimizations, thereby improving production efficiency and ensuring equipment quality meets standards. Furthermore, the real-time data and alarm information from this invention can be further mined and analyzed to provide strong support for continuous improvement and innovation in enterprises. In the future, with continuous technological advancements and expanding application scenarios, this invention will play an increasingly important role in various industries, promoting the sustainable development of the aviation manufacturing industry, reducing resource waste, and improving resource utilization.

[0018] Furthermore, by systematically collecting and analyzing the data gathered in this invention, we can more accurately assess the risks in the production process, formulate more scientific management strategies, and improve overall management level and emergency response capabilities.

[0019] This invention is easy to use and stable, reducing operational difficulty and improving work efficiency. Furthermore, it can be further combined with big data analysis and machine learning algorithms to predict the probability of potential risks and perform preventative maintenance in advance, thereby minimizing production interruptions and losses, and making it applicable to a wider range of assembly and manufacturing scenarios.
