Description

Technical Field

[0001] The present invention relates to the field of fire protection acceptance, and in particular to a device and method for acceptance of building fire protection equipment. Background Art

[0002] Fire acceptance inspection refers to the fire inspection qualification investigation conducted by the fire department on enterprises and institutions when they are completed and put into operation. When the construction unit conducts fire acceptance inspection, the fire department needs to conduct safety inspections and investigations, and at the same time, it needs to issue a certificate of electrical fire inspection qualification. Electrical fire inspection has been included in the mandatory inspection items for fire acceptance inspection by the Ministry of Public Security.

[0003] Currently, the acceptance of fire protection equipment in buildings is usually done manually by going inside the building to visually observe whether the size, installation location, fire protection components and other items of the fire protection equipment are installed correctly, whether the fire protection equipment is qualified, and whether it is consistent with the fire protection content in the planning and design drawings. This is not only a large workload and high mental labor intensity, but also there are problems of missed inspections and wrong judgments by the naked eye, and even favoritism, fraud and bribery by inspectors, which affects the speed, accuracy and fairness of fire protection acceptance.

[0004] Furthermore, manual inspections rely on the inspector's experience, subject to subjective judgment, and result in a high missed inspection rate of 3.7% (according to 2019 Fire Protection Association statistics). Paper records are easily tampered with, and the acceptance process lacks credible evidence, resulting in 3.2% of acceptance disputes being untraceable (according to the 2021 Ministry of Housing and Urban-Rural Development case database). Existing automated inspection equipment has limited functionality. For example, patent CN112270721A utilizes only image recognition, which is unable to verify key parameters such as the pressure vessel's condition. Unscientific path planning in complex building environments leads to 15%-20% of repeated inspections (according to the Shenzhen Fire Department's 2022 research report).

[0005] Based on this, the present invention is designed. Summary of the Invention

[0032] The present invention proposes a building fire protection equipment acceptance device, which obtains images of fire protection equipment in the building through SLAM positioning modules and cameras, and constructs a three-dimensional digital twin model of the building. Based on the ant colony algorithm, the optimal inspection path covering all fire protection equipment is generated, and then the sensor matrix is ​​synchronously triggered when moving along the optimal inspection path to collect five-dimensional equipment feature data of visible light images, infrared thermal images, laser ranging data, RFID electronic identification, and environmental soundprints.

There is no need to manually observe with the naked eye whether the fire-fighting equipment is qualified. The inspection route planning is scientific and reasonable, there is no repeated inspection, and the inspection records are not easy to tamper with. The acceptance process saves a large amount of credible evidence. The equipment is simple and convenient to operate, saving time and effort, and the workload is small, which greatly reduces the work intensity of the inspector and completely eliminates the problems of missed inspections, wrong inspections, and favoritism and bribery by inspectors, making the acceptance work fair, orderly, accurate and efficient. At the same time, it can verify key parameters such as the status of pressure vessels, with rich functions and good practicality.

[0033] The following describes in detail the building fire protection equipment acceptance device of the present invention using two embodiments.

[0034] Example 1: Figure 1As shown, the building fire equipment acceptance device includes a control box 1, a telescopic rod 7 and a cloud computer 6. The control box 1 is provided with a battery, an antenna, a touch screen 4, a speaker 5, a memory, a controller, a SLAM positioning module, a sensor matrix, and an edge computing unit. The battery, antenna, memory, controller, SLAM positioning module, sensor matrix, and edge computing unit are located in the control box 1. The touch screen 4 and the speaker 5 are located on the outer wall of the control box 1. The control box 1 has a box cover 2. The battery is used to power the building fire equipment acceptance device. The antenna is used for wireless interconnection between the control box 1 and the cloud computer 6. The touch screen 4 is used for manual input of operation instructions to control the visual camera 10, motor 1 22, motor 23, and control valve 14 to move, and display the fire equipment acceptance result information. The speaker 5 is used to broadcast the fire equipment acceptance result in language. The memory is used to store the visual camera 10, SLAM positioning module, sensor matrix, edge computing unit. The image data information generated by the computing unit is for future review. The controller is used to control the action of motor 1 22, motor 23, and control valve 14. The lower end of the telescopic rod 7 is fixedly connected to the control box 1. The upper end of the telescopic rod 7 is equipped with a visual camera 10. The visual camera 10 is used to capture images of fire-fighting equipment in the building and transmit the images to the control box 1 for storage in the memory. At the same time, the images are wirelessly transmitted to the cloud computer 6 via the antenna with the help of the Internet. The cloud computer 6 identifies and analyzes the images to identify the fire-fighting equipment in the building in the image. Before the visual camera 10 starts shooting, the design distribution drawings of the fire-fighting equipment in the building are first input into the cloud computer 6 for subsequent data comparison. If the comparison results are consistent, the acceptance is qualified. Otherwise, the acceptance is unqualified. The cloud computer 6 transmits the acceptance results to the control box 1 wirelessly via the Internet, which are then played out by the speaker 5 and displayed on the touch screen 4, including the reasons for the unqualified acceptance.

[0035] In this embodiment, the cloud computer 6 can be set up in the fire control center. When the inspector goes out for fire inspection, he only needs to carry the control box 1, the telescopic rod 7, and the visual camera 10. The cloud computer 6 is wirelessly connected to the control box 1 to analyze and process the image data information sent back by the control box 1 in real time.

[0036] In this embodiment, considering that there are many fire-fighting equipment in the building and they are distributed in many places, it is necessary for a person to carry the control box 1 and move around in the building to take pictures and locate all the fire-fighting equipment. In order to facilitate the movement of the control box 1 in the building, Figure 1 As shown, the control box 1 is provided with a shoulder strap 3, and a person can carry the control box 1 through the shoulder strap 3 and walk around in a building. Then, the length of the telescopic rod 7 is adjusted according to the person's height to make the visual camera 1 a certain distance above the head. Then, the person can carry the control box 1 and walk around in the building to complete the shooting work of the visual camera 10.

[0037] In this embodiment, the visual camera 10 has an anti-shake function so that clear images can be captured even when the visual camera 10 is moving. This is a common function of conventional cameras and will not be described in detail herein.

[0038] Furthermore, in order to improve the anti-shake performance of the visual camera 10 and further improve the image capture clarity, as Figure 1 and Figure 2 As shown, a mounting rod 8 is fixedly mounted on the upper end of the telescopic rod 7, a hanging rope 9 is hung on the mounting rod 8, and the visual camera 10 is hung on the lower end of the hanging rope 9. A mounting bracket 11 and a gyroscope 12 are fixedly mounted on the visual camera 10, and the gyroscope 12 is used to obtain the swing direction of the visual camera 10. Because the visual camera 10 is suspended at the lower end of the hanging rope 9, when a person carries the control box 1 and walks, the visual camera 10 will inevitably swing around the hanging rope 9. Although the visual camera 10 itself has an anti-shake function, when the visual camera 10 swings around the hanging rope 9 with a large amplitude, it will still affect the image capture clarity. Therefore, it is necessary to improve the anti-shake performance of the visual camera 10 to further improve the image capture clarity. Figure 2 As shown, a mounting box 13 is installed on the mounting frame 11, and a plurality of control valves 14 are installed on the mounting box 13 and are centrally symmetrically distributed with the hanging rope 9 as the center. The outlet of the control valve 14 is connected to the jet pipe 15, and the jet pipe 15 is arranged horizontally. The jet directions of the jet pipes 15 of the plurality of control valves 14 are centrally symmetrically distributed with the hanging rope 9 as the center. Preferably, there are four control valves 14, and they are located in the four directions of east, west, south and north of the mounting box 13. The four control valves 14 spray in the four directions of east, west, south and north respectively.

[0039] In this embodiment, a gas tank is provided in the control box 1, and the control valve 14 is connected to the gas tank through an air pipe 16. The air pipe 16 runs through the telescopic rod 7. When the controller controls the control valve 14 to open, the air jet 15 of the control valve 14 ejects air outward. In this design, the gas recoil force can be used to keep the visual camera 10 stable and prevent it from swinging around the hanging rope 9. Specifically, the swing direction of the visual camera 10 is obtained in real time by the gyroscope 12, and then the controller controls one or more control valves 14 to open and eject gas to generate gas recoil force. The opening degree of each control valve 14 is different, and the corresponding gas recoil force generated is also different. The purpose of this design is to make the resultant direction of the gas recoil force opposite to the swing direction of the visual camera 10, so as to use the gas recoil force to stop the visual camera 10 from swinging, keep the posture stable, and prevent it from swinging around the hanging rope 9, thereby solving the problem that the visual camera 10 swings around the hanging rope 9 when a person carries the control box 1 and walks, affecting the clarity of the captured image.

[0040] Example 2: This example is a further improvement made on the basis of Example 1.

[0041] In this embodiment, if Figure 3 and Figure 4 As shown, the lower end of the telescopic rod 7 is detachably fixedly connected to the control box 1. This design makes it easy to separate the telescopic rod 7 and the control box 1. The lower end of the telescopic rod 7 is detachably fixedly installed with a bracket 17, and the bracket 17 is used to vertically set the telescopic rod 7 on the ground.

[0042] In this embodiment, if Figure 3 and Figure 4 As shown, the upper end of the telescopic rod 7 is provided with a shell that rotates around the telescopic rod 7, and the shell is connected to the motor 1 22 in a transmission manner. The motor 1 22 is fixedly installed in the telescopic rod 7, and the shell is driven to rotate around the telescopic rod 7 by the motor 1 22. The shell includes a spherical shell 19 and a spherical cover 20 that are detachably connected. A splint 21 is fastened between the spherical shell 19 and the spherical cover 20. The output shaft of the motor 1 22 is fixedly connected to the splint 21. A motor 23 is fixedly installed in the spherical shell 19. The spherical shell 1 9 is provided with a long through hole 24, one end of the mounting rod 8 is hung with a sling 9, and the other end passes through the long through hole 24 and is connected to the output shaft of the motor 23. The mounting rod 8 is slidably connected to the long through hole 24, and the mounting rod 8 is driven up and down by the motor 23. A pair of clamping arms 25 are fixedly installed at one end of the mounting rod 8, and the visual camera 10 can be clamped and fixed by a pair of clamping arms 25. During acceptance, the telescopic rod 7 is first vertically set on the ground through the bracket 17, and then the control box 1 is removed to avoid The visual camera 10 is affected to shoot, and then the touch screen 4 is operated to turn on the visual camera 10, and the motor 1 22 is controlled to drive the visual camera 10 to rotate around the telescopic rod 7 to shoot the image of the fire-fighting equipment. During the shooting process, the motor 2 23 is controlled as needed to drive the visual camera 10 to swing up and down around the motor 2 23 to ensure that the image of the fire-fighting equipment is shot without omission. This design saves the trouble of people carrying the control box 1 and moving the visual camera 10 in the building to shoot all the fire-fighting equipment, further saving manpower, greatly reducing the workload of the inspectors, and improving the speed and efficiency of shooting fire-fighting equipment. It is very suitable for shooting fire-fighting equipment in indoor spaces with a square space. The building fire-fighting equipment acceptance device in Example 1 is suitable for shooting fire-fighting equipment in narrow and long indoor spaces such as corridors, because in indoor spaces with a square space, the visual camera 10 can shoot all the differences in the room by rotating one circle, while in narrow and long indoor spaces such as corridors, people must carry the visual camera 10 from one end of the corridor to the other to shoot all areas in the corridor.

[0043] In this embodiment, if Figure 3 As shown, the telescopic rod 7 and the control box 1 are connected via a protective tube sleeve 18 , which is sleeved on the outside of the gas pipe 16 , the wires, and the signal lines to protect the gas pipe 16 , the wires, and the signal lines.

[0044] Embodiment 3: This embodiment is a further improvement made on the basis of embodiment 1 or embodiment 2.

[0045] In Example 1 and Example 2, the control box 1 is carried by a person and moved within the building to photograph and locate all fire-fighting equipment. In this embodiment, in order to reduce the burden on the staff, a robot dog can be added, and the control box 1 can be detachably fixed on the robot dog. The robot dog carries the control box 1 within the building to photograph and locate all fire-fighting equipment. This saves the trouble of a person carrying the control box 1 within the building to photograph and locate all fire-fighting equipment, saves time and effort, and the robot dog can be a robot dog in the existing technology.

[0046] In addition, the present invention also proposes a building fire protection equipment acceptance method, which uses the aforementioned building fire protection equipment acceptance device to perform the following steps: S1. Move the visual camera 10 and the SLAM positioning module inside the building to capture images of firefighting equipment, build a three-dimensional digital twin model of the building, and generate an optimal inspection path covering all firefighting equipment based on an ant colony algorithm; S2, while moving along the optimal inspection path, synchronously triggers the sensor matrix to collect five-dimensional device feature data including visible light images, infrared thermal images, laser ranging data, RFID electronic identification, and environmental soundprints; S3: Perform initial device compliance screening through edge computing units, and cloud computers use deep neural networks to perform multimodal data fusion analysis and calculate device status credibility scores; S4. Write the acceptance data to the blockchain network in real time, generate a hash certificate containing a time and space stamp, and use a cloud computer to compare the three-way consistency of the fire equipment ledger, maintenance records, and inspection data; S5. If the comparison results are consistent, the fire-fighting equipment is accepted and the loudspeaker is controlled to broadcast the information; S6. If the comparison results are inconsistent, the fire-fighting equipment will fail the acceptance inspection, and the loudspeaker will be controlled to announce the reason for the failure.

[0047] Specifically, the step S1 of moving the visual camera 10 in the building to capture images of firefighting equipment includes a person carrying the control box 1 and walking in the building to drive the visual camera 10 to move in the building to capture images of firefighting equipment.

[0048] In this embodiment, further, when a person carries the control box 1 and walks in the building, driving the visual camera 10 to move in the building to capture images of fire-fighting equipment, the visual camera 10 is suspended at the lower end of the suspension rope 9 to capture images of fire-fighting equipment, and the swing direction of the visual camera 10 is obtained in real time through the gyroscope 12; the controller controls the control valve 14 to open the jet to generate a gas recoil force, and the resultant force direction of the gas recoil force is opposite to the swing direction of the visual camera 10. The gas recoil force is used to stop the visual camera 10 from swinging, keep its posture stable, and prevent it from swinging around the suspension rope 9.

[0049] In this embodiment, the visual camera 10 in the second embodiment is moved inside the building to capture images of firefighting equipment, including: Place the telescopic rod 7 vertically inside the building; Clamp the visual camera 10 with a pair of clamping arms 25; Turn on the visual camera 10, and control the motor 1 22 to drive the visual camera 10 to rotate around the telescopic rod 7 to capture images of the firefighting equipment; The second motor 23 is controlled to drive the visual camera 10 to swing up and down around the second motor 23 to capture images of the fire-fighting equipment.

[0050] In this embodiment, the SLAM positioning module integrates a UWB ultra-wideband positioning unit and an IMU inertial measurement unit, and performs centimeter-level positioning through extended Kalman filtering; The ant colony algorithm sets dynamic pheromone update rules:
