Description

Technical Field

[0001] The present invention relates to a monitoring device, and in particular to a remote monitoring device based on the Internet of Things applied in the monitoring field. Background Art

[0002] As the intelligent driving systems of cars have become more and more mature in recent years, more and more customers are willing to buy cars with intelligent driving systems. However, the on-board laser radar, one of the most important components of the intelligent driving system, has invisibly caused harm to monitoring equipment.

[0003] For example, the specification of Chinese patent CN202410443440.8 discloses a method and system for preventing laser ablation of a camera based on v2x. It is a solution to prevent the camera of a smart driving vehicle from being damaged by ablation of the laser radar of another vehicle. The patent mentions that when the object irradiated by the vehicle-mounted laser is a camera, the CMOS of the camera will convert the light signal into an electrical signal when it receives the light. When the light is very strong, the current generated inside the CMOS is also very large. Of course, the CMOS can adjust the magnitude of this current, that is, the sensitivity ISO adjustment. If the camera is in a high ISO state and is irradiated by a laser at the same time, it is very likely that the CMOS will be damaged by ablation, causing damage to the camera. Since home monitoring equipment also uses CMOS image sensors, the above situation will also occur, so we propose a remote monitoring device based on the Internet of Things.

[0004] For example, the specification of Chinese patent CN201910835372.9 discloses a magnetically driven self-switching infrared monitor, which introduces a method of using a temperature switch to control the switching between loading and unloading of an infrared polarizer by detecting temperature. The disadvantage is that it does not take into account the damage of the vehicle-mounted laser radar to the camera chip of the monitoring equipment, and its magnetically driven switching device installs magnetic materials on the frame of the infrared polarizer, so that a black light strip will flash in the monitoring image when the infrared polarizer is switched, thereby affecting the monitoring image.

[0005] Commonly used household monitoring equipment on the market cannot effectively protect against vehicle-mounted laser radars. Although some of the above-mentioned monitoring equipment are equipped with infrared polarizers to filter out strong light during the day, which indirectly prevents the CMOS image sensors of the monitoring equipment from being damaged by vehicle-mounted laser radars during the day, on rainy days or at night, the infrared polarizers will be automatically removed due to weak light, and the protection effect cannot be achieved at this time. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the home monitoring device in the prior art cannot protect the vehicle-mounted radar on rainy days or at night, resulting in damage to the CMOS image sensor.

[0007] To solve the above problems, the present invention provides a remote monitoring device based on the Internet of Things, including a light source collector and a light source analyzer, the light source collector including a shell, an integrated module installed in the shell, a lens switching mechanism and a monitoring lens fixed at one end of the integrated module, and the lens switching mechanism is located between the monitoring lens and the integrated module, the lens switching mechanism and the monitoring lens are fixed together inside a geometric body formed by the shell and the integrated module, the light source analyzer includes an image acquisition module, an image analysis module and a switching module, the image analysis module is electrically connected to the image acquisition module and the switching module respectively, and the light source analyzer is installed in the integrated module.

[0008] In the above-mentioned remote monitoring equipment based on the Internet of Things, it is possible to prevent the CMOS image sensor of the monitoring device from being damaged by the vehicle-mounted laser radar.

[0009] As a further improvement of the present application, the lens switching mechanism is installed with an infrared polarizer, one end of which is fixed on a moving rod, the moving rod is arranged in a sliding groove opened on the frame, the moving rod moves vertically along the sliding groove, mounting ears are arranged on both sides of the frame, an electromagnet is fixed at the lower end of the mounting ear, and the switching module is electrically connected to the electromagnet.

[0010] As a further improvement of the present application, a rebound device is installed in the lens switching mechanism, one end of the rebound device is fixed to the outermost end of the moving rod, and the other end is fixed to the bottom end of the frame.

[0011] As a further improvement of the present application, the rebound device is perpendicular to the bottom of the frame, and the rebound device is installed on both sides of the frame.

[0012] As another improvement of the present application, both sides of the moving rod are made of magnetic material.

[0013] As another improved supplement of the present application, a light compensation structure installed on the shell is provided on the periphery of the monitoring lens, and a transparent shell is fixed to one end of the light compensation structure located on the lamp bead side.

[0014] As another improved supplement of the present application, the light compensation structure is installed with a variety of lamp beads, and the lamp beads are arranged in an array on the light compensation circuit board.

[0015] As another improvement of the present application, a photosensitive element is installed on the top of the shell, the photosensitive element is electrically connected to the image analysis module, and the switching module is electrically connected to the electromagnet and the lamp bead respectively.

[0016] To summarize, in this application, when the natural light intensity is weak, the image analysis module will analyze the image transmitted by the image acquisition module to detect whether there are any vehicles equipped with laser radar entering the monitoring range. After finding the corresponding vehicle, the image analysis module acts on the switching module to make the switching module transmit an action signal, so that the electromagnet of the lens switching mechanism is energized, attracting the moving rod with the infrared polarizer fixed to move upward, and finally realizing the loading of the infrared polarizer. When the corresponding vehicle leaves the monitoring range, the image analysis module controls the switching module to make the action signal transmitted by the switching module disappear, the electromagnet loses power, and the rebound device acts on the moving rod to pull the infrared polarizer downward, thereby removing the infrared polarizer. In the above manner, it is not easy for the vehicle-mounted radar to damage the CMOS image sensor of the monitoring equipment on rainy days or at night. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-Figure 3The remote monitoring device based on the Internet of Things shown includes: a light source collector and a light source analyzer, characterized in that the light source collector includes a shell 5, an integrated module 1 is installed in the shell 5, a lens switching mechanism 2 and a monitoring lens 3 are fixed at one end of the integrated module 1, and the lens switching mechanism 2 is located between the monitoring lens 3 and the integrated module 1, and the lens switching mechanism 2 and the monitoring lens 3 are fixed together inside a geometric body formed by the shell 5 and the integrated module 1; the light source analyzer includes an image acquisition module, an image analysis module and a switching module, the image analysis module is electrically connected to the image acquisition module and the switching module respectively, and the light source analyzer is installed in the integrated module 1, so that the monitoring component is precise, compact, occupies little space, and is easy to place.

[0020] Another example Figure 4-Figure 5 The lens switching mechanism 2 shown is equipped with an infrared polarizer 9, one end of which is fixed on a moving rod 10, and the moving rod 10 is arranged in a sliding groove 13 opened on the frame 8, so that the infrared polarizer 9 has a fixed sliding range in the frame 8, mounting ears 7 are arranged on both sides of the frame 8, and an electromagnet 12 is fixed at the lower end of the mounting ear 7, and the switching module is electrically connected to the electromagnet 12, and both sides of the moving rod 10 are made of magnetic material, and the electromagnet 12 has a magnetic property when energized, so that when the electromagnet 12 is energized and has magnetism, it will attract the moving rod 10 to move upward, and a rebound device 11 is installed in the lens switching mechanism 2, one end of the rebound device 11 is fixed to the outermost end of the moving rod 10, and the other end is fixed to the bottom end of the frame 8, and the purpose of installing the rebound device 11 is to pull the moving rod 10 to move downward, the rebound device 11 is perpendicular to the bottom of the frame 8, and the rebound device 11 is installed on both sides of the frame 8, so that the switching mechanism has a faster response speed.

[0021] In summary, under the condition that the device can output good monitoring images with only weak natural light in full-color low-light mode, the working process of the device is: the photosensitive element 16 converts the natural light intensity from an analog signal into an electrical signal and sends it to the image analysis module. The image analysis module determines the intensity of the light according to the electrical signal. Once a vehicle-mounted laser radar appears within the monitoring range, the image acquisition module will acquire the picture and transmit it to the image analysis module. The image analysis module will identify the vehicle-mounted laser radar, and then control the lens switching mechanism 2 through the switching module to execute the command to load the infrared polarizer 9. The electromagnet 12 in the lens switching mechanism 2 is energized by the switching module, and the electromagnet 12 has magnetic force to attract the moving rod 10 along the frame 8. The sliding groove 13 moves upward to realize the loading of the infrared polarizer 9, thereby preventing the CMOS image sensor 15 in the integrated module 1 from being damaged. When the image acquisition module transmits an image in which there is no longer any on-board laser radar, the image analysis module controls the lens switching mechanism 2 through the switching module to execute the command to remove the infrared polarizer 9. The electromagnet 12 in the lens switching mechanism 2 is de-energized by the switching module, and the magnetic force of the electromagnet 12 disappears. The rebound device 11 acts on the moving rod 10 to move downward along the sliding groove 13 to realize the removal of the infrared polarizer 9. This method can achieve a better monitoring effect under weak natural light conditions and protect the CMOS image sensor 15 of the monitoring device.

[0022] The second implementation method: Different from the first implementation, the second implementation is aimed at extremely weak light conditions where the monitoring device still needs to use light compensation to obtain a good monitoring image under full-color low-light function, such as Figure 2-Figure 7 The light compensation structure 4 shown is arranged on the periphery of the monitoring lens 3, and a transparent shell 6 is fixed on one end of the light compensation structure 4 on the side of the lamp bead 14. The light compensation structure 4 and the transparent shell 6 are fixed in the shell 5 together. The purpose of installing the transparent shell 6 is to minimize the attenuation efficiency of the light compensation structure 4 and reduce energy loss. The light compensation structure 4 is installed with a variety of lamp beads 14, and the lamp beads 14 are arranged in an array on the light compensation circuit board 17. The lamp beads 14 have two types of visible light and invisible infrared light. The usage conditions are as follows: when there is no vehicle-mounted radar and the natural light is extremely weak, infrared light is used for light compensation to reduce the discomfort caused by strong light to the human eye in the dark. When there is a vehicle-mounted radar and the natural light is extremely weak, visible light is used to eliminate the danger of unclear monitoring due to the installation of an infrared polarizer. The switching module is electrically connected to the lamp bead 14 to realize the switching module controlling the lamp bead 14 for light compensation.

[0023] Figure 2-Figure 8The remote monitoring device based on the Internet of Things is shown. The working process of the device under extremely weak light conditions is as follows: the electrical signal sent to the image analysis module by the photosensitive element 16 is identified. When the lighting conditions are extremely poor, the image analysis module will control the light compensation structure 4 through the switching module to perform infrared light compensation, so as to achieve a fairly good monitoring effect without affecting human night vision. Under this condition, if a vehicle-mounted laser radar appears within the monitoring range, the image analysis module will not only control the lens switching mechanism 2 through the switching module to execute the command to load the infrared polarizer 9, but also control the light compensation structure 4 through the switching module to switch from infrared light compensation to visible light compensation. When the vehicle-mounted laser radar drives out of the monitoring range, the image analysis module will control the lens switching mechanism 2 through the switching module to execute the command to remove the infrared polarizer 9, and will also control the light compensation structure 4 through the switching module to switch from visible light compensation to infrared light compensation. In this way, under extremely weak natural light conditions, not only a good monitoring state is achieved, but also the protection purpose of the CMOS image sensor 15 of the monitoring device is achieved.

[0024] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
