Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a smart home gas safety management system. Background Art

[0002] A pipe joint is a system for connecting, diverting or converging pipes. It provides an interface that allows different pipes to be connected together to achieve the transmission, diversion or converging of fluids or gases. It is a component used to connect and couple pipes. It plays the role of connecting, turning, diverting or converging in the pipe system. Pipe joints have different shapes and structures to adapt to various pipe layouts and requirements.

[0003] Common types of pipe joints include: 1. Threaded joint: a joint that connects and fixes pipes through threads. It is divided into internal threaded joints and external threaded joints, and is commonly used in low-pressure and small-diameter pipe systems. 2. Flange joint: a joint that connects pipes through flanges and bolts. Flange joints are commonly used in high-pressure and large-diameter pipe systems, and the connection and sealing of pipes are achieved through the connection and fixation of flanges. 3. Welded joint: a joint that connects pipes together through welding methods. Common welded joints include arc welding, gas shielded welding, etc., which are suitable for high-temperature, high-pressure and pipe systems with high sealing requirements. 4. Clamp joint: a joint that connects pipes together through a clamp. The clamp is usually made of metal or plastic, and is fixed to the pipe through a fastening system to form a tight connection.

[0004] Invention application CN113431979A discloses a disassembly and assembly device for a gas pipeline safety plug, comprising a knob, a slot, a fixing device, a rubber umbrella skirt head and a fixing bolt. The fixing device is provided, and the fixing device is threadedly connected to the gas pipeline through a threaded joint to seal the gas pipeline. An outer sealing ring is provided on the outside of the fixing device, and the sealing rubber on the inner side of the outer sealing ring is sleeved on the outer side of the gas pipeline to perform double-layer sealing on the gas pipeline, thereby increasing the sealing effect on the gas pipeline. A movable shell is provided on the outer side of the outer shell of the outer sealing ring, and the movable shell is supported by a spring. A rotating block and a protrusion are provided on the outer side of the outer shell and the inner side of the movable shell. The outer shell can be rotated only when the movable shell is pressed to align the positions of the rotating block and the protrusion, thereby preventing the outer shell from rotating easily and making it easy to loosen, thereby affecting the sealing effect on the gas pipeline, thereby increasing the plugging and sealing effect on the gas pipeline, and the disassembly and assembly are convenient and simple to use.

[0005] As one of the main facilities of gas pipelines, if the pipe joints use raw tape, it will increase the probability of flammability on site and cause safety hazards to the use of gas pipelines. Obviously, the existing technology lacks a monitoring mechanism for whether the pipe joints use raw tape, which leads to the possibility that the pipe joints of gas pipelines use raw tape. Summary of the invention

[0006] The present invention provides a smart home gas safety management system, which can solve technical problems in related fields. The system includes: A content acquisition device, arranged opposite to a pipe joint of the gas pipeline, for performing an image acquisition operation on the pipe joint to obtain and output a corresponding content acquisition image; A maximum value filtering device, connected to the content acquisition device, for performing maximum value filtering processing on the received content acquisition image to obtain and output a corresponding maximum value filtered image; A real-time filtering device, connected to the maximum filtering device, for performing Gaussian high-pass filtering on the received maximum filtering image to obtain and output a corresponding real-time filtering image; A gamma correction device, connected to the real-time filtering device, for performing gamma correction processing on the received real-time filtered image to obtain and output a corresponding gamma corrected image; an occlusion judgment component connected to the gamma correction device and comprising a curvature capture unit, a set detection unit and a scene analysis unit, wherein the set detection unit is respectively connected to the curvature capture unit and the scene analysis unit, and the occlusion judgment component is used to obtain each curvature value on the edge curve of the reference pattern of the pipe joint, detect the image area of ​​the pipe joint based on the brightness value interval corresponding to the pipe joint in the received gamma correction image, and obtain each curvature value of the edge curve of the image area, and when each curvature value on the edge curve of the reference pattern of the pipe joint does not correspond to each curvature value of the edge curve of the image area of ​​the pipe joint in quantity or value and the image area of ​​the pipe joint overlaps with the image area of ​​the raw tape body, it is judged that the pipe joint is occluded by the raw tape body, otherwise, it is judged that the pipe joint is not occluded by the raw tape body; An abnormality reporting component is connected to the obstruction judgment component and is used to perform network reporting of abnormal notification information of the raw tape body being used in the pipeline joint in violation of regulations when the obstruction judgment component determines that the pipeline joint is obstructed by the raw tape body; Wherein, the abnormality reporting component is further used for stopping the network reporting of abnormal notification information of the illegal use of the raw tape body for the pipeline joint when the blocking judgment component determines that the pipeline joint is not blocked by the raw tape body.

[0007] The smart home gas safety management system of the present invention is widely used and stable in operation. Since a visual analysis mechanism can be used to intelligently determine whether the pipe joint of the gas pipeline is blocked by the raw tape, it is convenient to identify and warn of abnormal environments where the pipe joint uses the raw tape in violation of regulations.
