Description

Technical Field

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

[0002] Smart home refers to the intelligent management of various electrical components in the home. For a home, the most used are water, electricity, and gas, among which gas (i.e. coal gas) management is particularly important, not only because people use gas for three meals a day, washing, etc., but also because gas leakage can easily cause very serious consequences.

[0003] Cooker is translated into Cooker in English. Cookers are divided into natural gas stoves, artificial gas stoves, liquefied petroleum gas stoves, and electromagnetic stoves according to the type of gas used. According to the material, they are divided into cast iron stoves, stainless steel stoves, and enamel stoves. According to the stove eyes, they are divided into single-eye stoves, double-eye stoves, and multi-eye stoves. According to the ignition method, they are divided into electric pulse ignition stoves and piezoelectric ceramic ignition stoves. According to the installation method, they are divided into desktop stoves and embedded stoves. The variety of household gas stoves has increased, the styles are novel, the safety measures have been strengthened, and the materials, functions, and performance have all been improved. There have also been improvements in production quality and reliability, process level, automation and intelligence, advanced performance indicators, energy saving and environmental protection, and safe use.

[0004] The main scenario for problems and failures of cookers is at the ignition site. For example, if the flameout protection component is missing at the ignition site, after the flameout occurs at the ignition site for various reasons, the lack of flameout protection will inevitably lead to natural gas leakage, which in turn causes various safety accidents, such as human gas poisoning or various gas accidents at the site.

[0005] The prior art discloses, for example, a gas leak alarm remote valve closing device, which includes a gas alarm for detecting information about gas and gas pipelines; a base station for uploading information to a data center; a data center for receiving detected gas information; a data acquisition module for acquiring CO concentration values, gas pipeline pressure values, and valve opening and closing states; a data calculation module for calculating a pressure difference between a pressure value and a minimum pressure standard that is too small, calculating a pressure difference between a pressure value and a maximum pressure standard that is too large, and calculating a ratio of an excessive pressure difference to a pressure difference threshold; a data alarm module for determining a CO concentration level and a gas pipeline state; and a data analysis module for determining whether to correct the minimum pressure standard, selecting a correction method for the minimum pressure standard, determining whether to adjust a medium flow rate, and selecting a method for adjusting the medium flow rate, thereby improving safety performance. Summary of the invention

[0006] The present invention proposes a smart home management system, the system comprising: a gas cut-off actuator, which is arranged inside the cooker and connected to the gas ignition assembly of the cooker, and is used to cut off the gas supply from the gas pipeline to the gas ignition assembly when receiving the first recognition command, and is also used to restore the gas supply from the gas pipeline to the gas ignition assembly when receiving the second recognition command; An explosion-proof camera mechanism is arranged inside the cooker and is used to perform a camera operation on the gas ignition environment inside the cooker to obtain and output a corresponding ignition environment image; A neighborhood interpolation device, disposed in the explosion-proof box and connected to the explosion-proof camera mechanism, is used to perform Lanczos interpolation processing of an 8-pixel×8-pixel neighborhood on the received ignition environment image to obtain and output a corresponding neighborhood interpolation image; A signal enhancement device, connected to the neighborhood interpolation device, for performing image frequency domain enhancement processing on the received neighborhood interpolation image to obtain and output a corresponding signal enhanced image; A filter mapping device, connected to the signal enhancement device, for performing impulse noise elimination and white noise elimination on the received signal enhancement image to obtain and output a corresponding filter mapping image; An intelligent analysis mechanism is arranged in the explosion-proof box body and connected to the filter mapping device, including a feature application unit, a brightness analysis unit and a detection execution unit, wherein the brightness analysis unit is respectively connected to the feature application unit and the detection execution unit, and the intelligent analysis mechanism is used to determine an image area matching the shape imaging feature corresponding to the flameout protection component from the filter mapping image as the image area to be analyzed according to the shape imaging feature corresponding to the flameout protection component, detect each background pixel point from the filter mapping image based on the brightness value range corresponding to the background, calculate the number of background pixel points existing in the image area to be analyzed, and issue a first recognition instruction when the number of background pixel points exceeds or is equal to a set number limit, and also issue a second recognition instruction when the number of background pixel points is less than the set number limit; The intelligent analysis mechanism is also connected to the gas-cutting actuator, and is used to wirelessly send the first recognition instruction or the second recognition instruction to the gas-cutting actuator.

[0007] The smart home management system of the present invention is stable in operation and safe in operation. When the flameout protection component is missing at the ignition site by using a visual analysis mechanism, the gas supply from the gas pipeline to the gas ignition component is cut off; otherwise, the gas supply from the gas pipeline to the gas ignition component is restored, thereby achieving safe and automatic management of the gas supply.
