Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
Examples
The embodiment provides a gas leakage monitoring device based on image recognition, as shown in fig. 1, including: the gas meter comprises a gas meter, an image collector, an image identification module, a judgment module and a power supply module.
The gas meter is used for measuring the change condition of the gas consumption, and in a specific implementation mode, the gas meter in the general gas meter on the market at present can be directly adopted, or the gas meter can be a corresponding device which is obtained by other modes such as customization, modification and the like and can realize the gas metering function. The gas meter is connected with the judging module, has an analog-to-digital conversion function, converts the measured gas flow into a digital signal and transmits the digital signal to the judging module. When indoor because use the gas or when taking place the gas leakage, the reading of gas meter can change, and the judgement module can draw when the reading changes according to the reading change situation of gas quantity, has indoor use gas or the condition that takes place the gas leakage.
The image collector is connected with the image identification module and is used for collecting working condition images of the gas equipment. The choice of the image collector is not limited, and for example, in a specific embodiment, a CCD high-definition camera is used. In a specific embodiment, the number of the CCD high-definition cameras is configured corresponding to the gas-using equipment, for example, if 1 gas stove and 1 water heater exist, 2 cameras are correspondingly configured and installed on the outer surface of the gas meter, and the lens of each camera is adjusted to enable the lens shooting area to be aligned to the directions of the gas stove and the water heater. The images taken by the camera are transmitted to an image recognition module, and in a specific embodiment, the camera is in a continuous working state.
The image recognition module is connected with the judgment module and used for recognizing the working condition image of the gas equipment, obtaining the working condition of the gas equipment and transmitting the working condition image to the judgment module.
