[0022] Please see Figure 1-4The embodiment provided by this invention: a machine vision-based real-time monitoring and emergency stop linkage system for personnel intrusion in a processing area, including an assembly plate 1 and a camera 2. A lifting rod 3 is fixedly connected to the bottom of the assembly plate 1. An electrical control box 4 is fixedly connected to one outer wall of the lifting rod 3. An energy storage device 5, a microprocessor 6, and a communication module 7 are installed inside the electrical control box 4. An audible and visual alarm 8 is installed on the outer wall of the electrical control box 4. A ball bearing 9 is fixedly sleeved at the bottom end of the lifting rod 3. A motor 10 is fixedly connected to the outer wall of the lifting rod 3. A gear 11 is fixedly connected to the bottom output shaft of the motor 10. The outer side of the ball bearing 9... A gear ring 12 is fixedly sleeved on the side wall, and a gear 11 meshes with the gear ring 12. An L-shaped support rod 13 is fixedly connected to the bottom of the gear ring 12. A mounting plate 14 is inserted into the L-shaped support plate, and a connecting plate 15 is fixedly connected to the bottom end of the mounting plate 14. The bottom end of the connecting plate 15 is fixedly connected to the camera 2. Specifically, the start of the motor 10 can cause the gear 11 on the output shaft to rotate. At this time, the gear 11 will mesh with the gear ring 12 on the outer ring of the ball bearing 9, thereby realizing the rotation of the L-shaped support rod 13. At this time, the mounting plate 14 installed on it will cause the camera 2 to rotate accordingly, thereby realizing the adjustment of the angle of the camera 2.

[0023] In this embodiment, the output terminal of the storage device 5 is electrically connected to the microprocessor 6, the output terminal of the microprocessor 6 is electrically connected to the audible and visual alarm 8, the communication module 7 and the motor 10, and the communication module 7 is connected to the external emergency stop switch signal.

[0024] As a technical optimization of the present invention, the camera 2 realizes image monitoring of the area, and the monitoring signal is sent to the microprocessor 6 in the electrical control box 4. The microprocessor 6 receives the signal and encodes it. When personnel are detected to have entered, the microprocessor 6 controls the sound and light alarm 8 to start. At the same time, the communication module 7 sends a signal to the emergency stop switch between the processing areas to control the shutdown of the equipment.

[0025] In this embodiment, the top of the mounting plate 14 is provided with a cavity, and the mounting plate 14 is provided with two sliding openings communicating with the cavity. A support rod 16 is fixedly connected in each of the two sliding openings. A traction plate 17 is slidably sleeved on the support rod 16. A wedge-shaped block 18 is fixedly connected to one side of the traction plate 17. A first spring 19 is sleeved on the support rod 16. The two ends of the first spring 19 are fixedly connected to the traction plate 17 and the inner wall of the sliding opening, respectively.

[0026] As a technical optimization of the present invention, during installation, the mounting plate 14 is inserted into the L-shaped support rod 13. At this time, the two wedge-shaped blocks 18 are compressed and retracted into the cavity. After the mounting plate 14 is inserted, the rebound force of the first spring 19 causes the wedge-shaped blocks 18 to return to the initial position, thereby fixing the mounting plate 14.

[0027] In this embodiment, the top of the connecting plate 15 is provided with two symmetrically arranged grooves, and a slide rod 20 is fixedly connected in each of the two grooves. Two sliders 21 are slidably sleeved on the slide rod 20. A second spring 22 is fixedly connected between the two sliders 21. A swing rod 23 is rotatably connected to the top of the slider 21, and a pressure plate 24 is rotatably connected to the top of the swing rod 23.

[0028] As a technical optimization of the present invention, the pressure plate 24 presses against the L-shaped support rod 13, pushes the swing plate to make the slider 21 move on the slide rod 20, and uses the second spring 22 to push down the connecting plate 15, so that the pressure stability between the wedge-shaped block 18 and the L-shaped support rod 13 is higher.

[0029] In this embodiment, both sides of the mounting plate 14 are provided with through openings communicating with the cavity, and the wedge-shaped locking block 18 is slidably inserted into the through opening.

[0030] As a technical optimization of the present invention, the wedge-shaped card block 18 is provided with sliding support.

[0031] In this embodiment, the inclined surface on the wedge-shaped block 18 is set with a polished structure.

[0032] As a technical optimization of the present invention, the frictional resistance during pressure is reduced.

[0033] The working principle of the machine vision-based real-time monitoring and emergency stop linkage system for personnel intrusion in the processing area is described in detail below: First, the start of motor 10 causes gear 11 on the output shaft to rotate. At this time, gear 11 will mesh with the toothed ring 12 on the outer ring of ball bearing 9, thereby realizing the rotation of L-shaped support rod 13. At this time, the mounting plate 14 installed on it will cause camera 2 to rotate accordingly, realizing the adjustment of the camera 2 angle. Camera 2 realizes image monitoring of the area. The monitoring signal is sent to microprocessor 6 in electrical control box 4. Microprocessor 6 receives the signal and encodes it. When personnel intrusion is detected, microprocessor 6 controls the sound and light alarm 8 to start. At the same time, the communication module 7 sends a signal to the emergency stop switch between processing areas to control the shutdown of the equipment.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
