Technical Field

[0001] The utility model belongs to the field of door leaf opening identification technology, and specifically relates to an AI and 5G-based intelligent identification and alarm device for the opening and closing of fire protection box doors and distribution box doors. Background Art

[0002] In today's society, fire and electrical safety are of paramount importance. Fire extinguisher boxes and distribution boxes are important safety facilities, and the correct closing state of their doors plays a key role in ensuring public safety and the normal operation of equipment.

[0003] For example, Chinese patent authorization announcement number CN212583567U discloses an easy-to-install door magnetic sensor for fire doors. When the permanent magnet on the square rod connected to the door magnetic body starts to move, the radio wave signal is immediately fed back to the fire department, so that the fire department can monitor the fire situation in a timely manner.

[0004] However, traditional methods for detecting the status of fire extinguisher and distribution box doors are relatively simple, often relying on simple mechanical structures or a single type of sensor. For example, using only a door magnetic sensor can be affected by external magnetic fields, leading to misjudgment, or unable to accurately detect the door status if the sensor malfunctions.

[0005] With the continuous advancement of science and technology, 5G communications and artificial intelligence (AI) technologies are becoming increasingly mature. 5G technology boasts high speeds, low latency, and large capacity, enabling the rapid transmission of large amounts of data. AI technology possesses powerful capabilities in image recognition and data analysis. Applying these two advanced technologies to intelligent identification and alarm systems for the opening and closing of fire hydrant and distribution box doors is an inevitable trend in improving safety management.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, an AI and 5G-based intelligent recognition and alarm device for fire protection box door and distribution box door opening and closing includes a door magnetic sensor 1, a camera 2, and a control host 3;

[0026] Among them, the door magnetic sensor 1 is installed on the door frame 6 and the door body 7, and is used to detect whether the door body 7 is open and output the status information of whether the door body 7 is open;

[0027] Specifically, such as Figure 1-3 As shown, the door magnetic sensor 1 includes a sensor main body 8 and a sensor split 9. The sensor main body 8 is fixedly connected to the door frame 6, and the sensor split 9 is fixedly connected to the door body 7. When the door frame 6 and the door body 7 are relative, it indicates that the door body 7 is in a closed state, and the sensor main body 8 outputs the status information of the closed state. When the door frame 6 and the door body 7 are staggered, it indicates that the door body 7 is in an open state, and the sensor main body 8 outputs the status information of the open state.

[0028] Here, the principles of the sensor main body 8 and the sensor split 9 are disclosed. The sensor split 9 is a permanent magnet with magnetic force. A reed switch is provided inside the sensor main body 8. When the permanent magnet and the reed switch are opposite to each other, the reed switch is in the disconnected state, the door magnetic sensor 1 does not work, and enters state one, which indicates the output status information of the closed state. When the door body 7 is opened, the permanent magnet and the reed switch are separated, the reed switch is closed, causing a short circuit, and entering state two, another set of status information indicating the open state can be sent.

[0029] Among them, the camera 2 is used to collect and output images of the door frame 6 and the door body 7;

[0030] Here, the door frame 6 and the door body 7 are installed inside the building, and the camera 2 can be installed at a position inside the building where it can capture the door frame 6 and the door body 7 , preferably at a position on the door frame 6 .

[0031] The door magnetic sensor 1 and the camera 2 are both electrically connected to a signal relay device 5. The signal relay device 5 and the control host 3 are connected via a 5G signal. The signal relay device 5 is used to transmit the status information output by the door magnetic sensor 1 and the image information output by the camera 2 to the control host 3;

[0032] The control host 3 is used to determine whether the door body 7 is in the open state according to the status information output by the door magnetic sensor 1 and the image information output by the camera 2;

[0033] The control host 3 is electrically connected to the alarm device 4. If the control host 3 determines that the door body 7 is in the open state, the alarm device 4 is automatically started to alarm. If the control host 3 determines that the door body 7 is in the closed state, the alarm device 4 is not started.

[0034] Specifically, the control host 3 first receives the status information output by the door magnetic sensor 1, and makes a first judgment on whether the door body 7 is open. Then, the characteristics of the image information are collected according to the AI model module of the control host 3, and this characteristic is compared with the opening characteristic and the closing characteristic of the door body 7. The AI model module can be used to make a second judgment on whether the door body 7 is open. If any one of the two judgments is in the open state, the alarm device 4 is activated to sound an alarm.

[0035] Specifically, collecting the features of image information through the AI model module and determining whether the door 7 is open is a mature existing technology. For example, the computer vision-based box abnormal state recognition method disclosed in the Chinese patent with authorization announcement number CN114429616B has been disclosed in detail and will not be described in detail in this technical solution.

[0036] Among them, another core of this technical solution is the improvement of the installation method of the door magnetic sensor 1. Specifically, both sides of the door body 7 and the sensor main body 8 are fixedly connected with a screw connection structure 10. Through the screw connection structure 10, the sensor split 9 and the screw connection structure 10 can be installed at different angles on the door frame 6 and the door body 7, which facilitates the installation of the sensor main body 8 and the sensor split 9.

[0037] like Figure 3-4 As shown, the screw connection structure 10 includes a sleeve 15 installed on one side of the sensor main body 8 or the sensor split 9, and the internal rotation of the sleeve 15 is connected to a rotating rod 16, and one end of the rotating rod 16 extends to the outside of the sleeve 15 and is fixedly connected to a nail ring 17. At this time, the sensor main body 8 and the sensor split 9 can be set vertically or horizontally according to the user's needs, and then the screws are passed through the nail ring 17. The sensor main body 8 and the sensor split 9 can be respectively installed on the door frame 6 and the door body 7 through the screw connection structure 10, which is suitable for fire box doors and distribution box doors with different structures.

[0038] Among them, such as Figure 4 As shown, the outer side of the sleeve 15 is fixedly connected with a fixed magnet 18, and the outer side of the rotating rod 16 is fixedly connected with a movable magnet 19. The fixed magnet 18 and the movable magnet 19 magnetically attract each other. When the pin ring 17 is rotated, the pin ring 17 can be initially fixed by the magnetic force between the fixed magnet 18 and the movable magnet 19. When the sensor main body 8 or the sensor split 9 is installed, the initial fixing force can be applied to the pin ring 17, which is convenient for the initial fixation of the pin ring 17 when the sensor main body 8 or the sensor split 9 is installed.

[0039] like Figure 4 As shown, a locking screw 20 is threadedly connected to the sleeve 15 , and the locking screw 20 can be threaded into the interior of the sleeve 15 and abut against the rotating rod 16 , thereby stably locking the angle between the nail ring 17 and the sleeve 15 .

[0040] like Figure 4 As shown, the screw connection structure 10 also includes a movable adjustment mechanism fixedly connected to the outside of the sensor main body 8 or the sensor split 9, and the sleeve 15 is assembled on the movable adjustment mechanism. At this time, by starting the movable adjustment mechanism, the relative positions between the sensor main body 8, the sensor split 9 and the nail ring 17 can be adjusted to adapt to more fire box door and distribution box door structures.

[0041] In addition, the movable adjustment mechanism includes a connecting side plate 11 fixedly connected to the outside of the sensor main body 8 or the sensor split 9, two side brackets 12 are fixedly connected to the connecting side plate 11, a screw 13 is rotatably connected between the two side brackets 12, and a slide 14 is threadedly connected to the outside of the screw 13, a sleeve 15 is fixedly connected to the outside of the slide 14, and the slide 14 is slidably connected to the connecting side plate 11. At this time, rotating the screw 13 can drive the slide 14 to move, adjust the position of the slide 14 and the nail ring 17, and after the adjustment is completed, lock the position of the slide 14 and the nail ring 17.

[0042] In summary, this technical solution detects whether the door body 7 is open by cooperating with the door magnetic sensor 1 and the camera 2, and can perform dual detection of whether the door body 7 is open by using sensor detection + visual detection, which greatly improves the accuracy of detection.

[0043] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
