Trigger-type infrared anti-theft monitoring alarm device is one of the common anti-theft monitoring equipment.

[0003] In the prior art, a triggered infrared anti-theft monitoring alarm device usually consists of three parts: an infrared sensor, a control host and an alarm device.

Infrared sensors generally include infrared transmitters and infrared receivers, and anti-theft monitoring is achieved through infrared cross-reflection. Infrared transmitters and infrared receivers are generally exposed to the external environment.

[0040] according to Figure 8 As shown, the locking assembly 8 includes a mounting plate 801, a micro cylinder 802 is fixedly mounted on the top of the mounting plate 801, a clamping plate 803 is fixedly mounted on the output end of the micro cylinder 802, a clamping shaft 804 is fixedly mounted inside the clamping plate 803, and a limiting rod 806 is fixedly mounted on the bottom of the clamping shaft 804.

[0043] according to Figure 5 , Figure 7 and Figure 9-10 As shown, two second shaped wheels 708 are movably embedded inside the rotating belt 712, and second rotating rods 709 are fixedly installed inside the two second shaped wheels 708. The top ends of the two second rotating rods 709 are movably embedded in the top surface inside one of the protective shells 1, and the bottom ends of the two second rotating rods 709 are movably embedded in the top of the fixed plate 16. An annular frame 710 is fixedly installed on the top of the fixed plate 16, and three arc-shaped limiting plates 711 are fixedly installed on the outer surface of the annular frame 710. The outer surfaces of the three arc-shaped limiting plates 711 are in contact with the inner wall of the rotating belt 712. The rotating belt 712 is conveniently supported by the annular frame 710 and the arc-shaped limiting plates 711, so that it rotates along a circular trajectory, and better drives the arc-shaped sliding plate 703 to move on the arc-shaped sliding rail 704. With the rotation of the rotating belt 712, the two second shaped wheels 708 and the second rotating rods 709 fixedly connected together are driven to rotate together, so as to facilitate the driving of the rotating belt 712 to rotate better.

Rotating holes 718 are provided on the outer surfaces of the two arc-shaped slide rails 704, and the outer surfaces of the two groups of pulleys 715 are movably embedded in the two rotating holes 718 respectively, so that when the arc-shaped sliding plate 703 moves along the arc-shaped slide rail 704, the plurality of pulleys 715 are driven to rotate inside the rotating holes 718, thereby reducing friction and facilitating better rotation of the arc-shaped sliding plate 703.

[0045] The effect and working principle of the whole mechanism are as follows: when in use, the rain and snow sensor 4, the forward and reverse motor 706, the micro cylinder 802, the micro hydraulic rod 901 and the PLC controller 15 are electrically connected, and two protective shells 1 are respectively installed on both sides of the door or window through two mounting frames 2, so that the infrared transmitter body 14 and the infrared receiver body 13 are respectively located on both sides of the door or window, and infrared light beams are emitted through the multiple infrared transmitter bodies 14 inside one of the protective shells 1, and are emitted to the infrared receiver body 13 through the transparent plate 10 and the anti-reflection coating film 11, and the infrared receiver body 13 receives the infrared light beams and transmits the receiving conditions to the external control processor by wireless means. When there is When an object passes through the infrared beam interval, it will block the emission of infrared rays. The infrared receiver body 13 will transmit the infrared abnormality to the control processor. At the same time, the infrared camera 6 will shoot the infrared beam interval and transmit the shot image information to the control processor. The control processor will identify and compare according to the received image information. When it is identified that the image is a cat or dog or a small animal, the alarm will not be triggered to prevent cats and dogs from entering by mistake and causing an alarm. With the cooperation of the infrared camera 6, the effect and accuracy of infrared anti-theft monitoring are improved. When the control processor identifies that the image is not a cat or dog or a small animal, it will be determined as an intruder. The infrared camera 6 will be used to shoot the image of the intruder to facilitate the collection of evidence. At the same time, the control processor will trigger an alarm. The alarm signal is transmitted to the alarm server, triggering the alarm to sound an alarm to deter intruders. The anti-reflection coating film 11 is usually a multi-layer film structure, and the thickness of each layer of the film is precisely controlled so that the incident light interferes between different film layers, so that the reflections of light within a certain wavelength range interfere with each other and weaken, thereby achieving the effect of reducing reflection and increasing transmittance. The infrared transmitter body 14 and the infrared receiver body 13 will pass through the anti-reflection coating film 11 when emitting and receiving infrared rays, thereby reducing the reflection of the transparent plate 10 on the infrared rays, allowing more infrared rays to pass through the transparent plate 10, increasing the transmittance, and helping to improve the sensitivity and accuracy of the sensor. The rain and snow sensor 4 is usually composed of two electrodes, forming a tiny Capacitor, in dry weather, the value of the capacitor is low, however, when raindrops or snowflakes touch the electrode surface, they will change the value of the capacitor, forming a new circuit path and increasing the value of the capacitor. By measuring the change in capacitance, the sensor can determine whether raindrops or snowflakes have landed on the electrode surface, thereby detecting the presence and intensity of rain and snow weather. The rain and snow sensor 4 can detect the external weather and transmit the detected information to the PLC controller 15 in the form of electrical signals. When the PLC controller 15 receives the information of rain and snow weather, the PLC controller 15 will control the forward and reverse motor 706 to start. The rotation path of the output end of the forward and reverse motor 706 is set in advance. After rotating the set path, it will automatically shut down.When the forward and reverse motor 706 is started again, its output end will rotate in the opposite direction and reset, and the first rotating rod 717 is driven to rotate through the output end of the forward and reverse motor 706, and the first work-shaped wheel 707 is driven to rotate, thereby driving the rotating belt 712 to rotate in a circular trajectory on the outer surface of the three arc-shaped limit plates 711. The three arc-shaped limit plates 711 do not contact each other. The first work-shaped wheel 707 and the two second work-shaped wheels 708 are respectively located between the two connected arc-shaped limit plates 711, which does not affect the normal rotation of the first work-shaped wheel 707 and the two second work-shaped wheels 708. With the rotation of the rotating belt 712, the two second work-shaped wheels 708 and the second rotating rod 709 fixedly connected together are driven to rotate together, so as to drive the rotating belt 712 to rotate better, and then drive one of them The arc-shaped sliding plate 703 slides on the outer surface of the arc-shaped slide rail 704, further driving the connecting frame 701 to move. At the same time, the arc-shaped sliding plate 703 at the bottom thereof rotates synchronously on the outer surface of the arc-shaped slide rail 704, which is conducive to improving the stability of the movement of the connecting frame 701, thereby driving the optical lens 702 to rotate to the transparent plate 10. At this time, the forward and reverse motors 706 are automatically turned off, so that the infrared light beams emitted by the multiple infrared emitter bodies 14 first pass through the optical lens 702 and the anti-reflection coating film 11, and then pass through the transparent plate 10 to be emitted. When the infrared light beam enters the optical lens 702, due to the refraction phenomenon, the light will bend and change its propagation direction. The optical lens 702 at the corresponding position of each infrared emitter body 14 is set with an appropriate shape (which can be based on According to the actual situation, appropriate materials and shape structures are selected to better control the refraction angle of light, make the infrared light beam more focused, and enhance the intensity of the infrared light beam, so as to improve the intensity of the infrared light signal received by the infrared receiver body 13, thereby improving the sensitivity of monitoring and reducing the probability of false alarms. The problem that the triggered infrared anti-theft monitoring alarm device includes an infrared transmitter and an infrared receiver, and when encountering rainy and snowy weather, it will scatter or absorb infrared light beams, causing the intensity of the light beam emitted by the infrared transmitter to weaken, reducing the sensitivity of monitoring, increasing the probability of false alarms, and failing to accurately judge whether there is an intrusion, affecting the accuracy of anti-theft monitoring, when the arc-shaped sliding plate 703 moves along the arc-shaped sliding rail 704, it drives multiple pulleys 715 to rotate in the rotating hole 718 rotates internally to reduce friction and facilitate better rotation of the arc-shaped sliding plate 703. When the forward and reverse motors 706 automatically pause, the PLC controller 15 starts the micro cylinder 802, and pushes the card plate 803 to move through the micro cylinder 802, and then pushes the card shaft 804 to move, and at the same time drives the limit rod 806 to move inside the limit hole 805. Through the cooperation of the limit rod 806 and the limit hole 805, the card shaft 804 is limited, which helps to improve its movement stability. The width of the outer surface of the card shaft 804 matches the width of the inside of the first work-shaped wheel 707. When the micro cylinder 802 automatically pauses, the card shaft 804 is just embedded in the inside of the first work-shaped wheel 707, clamping the rotating belt 712 in the first work-shaped wheel 707, and through the locking assembly 8,The position of the rotating belt 712 can be fixed and locked to prevent the rotating belt 712 from accidentally rotating or slipping, causing system instability or failure. The locking assembly 8 can prevent the rotating belt 712 from rotating or slipping when it stops, ensuring the accuracy and stability of its position. When it is detected that there is no rain or snow outside, the PLC controller 15 will start the forward and reverse motors 706 and the micro cylinder 802 again. The micro cylinder 802 pulls the card plate 803 and the card shaft 804 to reset, which does not affect the use of the rotating belt 712. The reverse rotation of the output end of the forward and reverse motor 706 drives the arc sliding plate 703, the connecting frame 701 and the optical lens 702 to reset, so that the optical lens 702 leaves the transparent plate 10, and the micro hydraulic rod 90 is started at the same time. 1. Push the cleaning brush 902 to move out of the cleaning slot 705, and at the same time drive the slide bar 903 to slide in the moving slot 904, which is conducive to improving the stability of the movement of the cleaning brush 902. When the micro hydraulic rod 901 is paused, the brush head of the cleaning brush 902 just moves to the anti-reflective coating film 11, and the cleaning brush 902 is driven to move together by the reverse movement of the connecting frame 701, so that the brush head of the cleaning brush 902 cleans the surface of the anti-reflective coating film 11, and can sweep away the attached dust and impurities, reducing the impact of dust and impurities on the anti-reflective coating film 11. When the forward and reverse motors 706 are automatically paused, the micro hydraulic rod 901 is started again, pulling the cleaning brush 902 to reset, which does not affect the use of the subsequent rotating assembly 7.

[0046] Among them, the rain and snow sensor 4, the infrared camera 6, the forward and reverse motor 706, the micro cylinder 802, the micro hydraulic rod 901, the anti-reflective coating film 11, the infrared receiver body 13, the infrared transmitter body 14 and the PLC controller 15 are all existing technologies, and their components and usage principles are all public technologies, so no excessive explanation will be given here.
