Figure 2 1 is a flow chart of an early warning method for electrical equipment according to an embodiment of the present application, and the flow chart includes the following steps:

[0030] Step S202, determining a plurality of device images obtained by performing image acquisition on a preset image acquisition area, wherein the preset image acquisition area includes at least electrical equipment;

[0031] It should be noted that the above-mentioned preset image acquisition area can be understood as a monitoring point for monitoring electrical equipment, such as an equipment cabinet where the electrical equipment is placed, or a position where the electrical equipment generates an arc in the equipment cabinet.

[0032] Step S204, determining a target device image from the multiple device images, wherein the target device image is an image captured when an arc is generated in the electrical device;

[0033] Step S206, determining the device operating temperature of the electrical device at the time when the target device image is collected;

[0034] Step S208: determining the warning information of the electrical device according to the device operating temperature and / or the target device image, and sending the warning information to the target object.

[0035] Through the above steps, multiple device images obtained by capturing images of a preset image capture area are determined, wherein the preset image capture area includes at least electrical equipment; a target device image is determined from the multiple device images, wherein the target device image is an image captured when the electrical equipment generates an arc; the device operating temperature of the electrical equipment at the time of capturing the target device image is determined; the warning information of the electrical equipment is determined based on the device operating temperature and / or the target device image, and the warning information is sent to the target object. The problem of how to send more accurate warning information of electrical equipment to users in the related art is solved, thereby improving the accuracy of the warning information.

[0036] In an exemplary embodiment, the process of determining the target device image from the multiple device images in the above-mentioned step S204 specifically includes: for a first device image among the multiple device images, determining a first image pixel point in the first device image; determining a first pixel point whose pixel value is greater than a preset pixel value from the first image pixel point, and generating a first pixel area based on the first pixel point; and determining the first device image as the target device image.

[0037] In an exemplary embodiment, the process of determining the target device image from the multiple device images in the above step S204 also includes: determining second image pixel points in a second device image among the multiple device images; determining second pixel points whose pixel values ​​are all greater than historical pixel values ​​from the second image pixel points, and generating second pixel areas based on the second pixel points; and determining the second device image as the target device image.

[0038] In an exemplary embodiment, a technical solution for determining the first device image as the target device image is further proposed, including: comparing the pixel median values ​​and historical pixel values ​​of multiple first pixel points to obtain a comparison result, wherein the historical pixel value is the pixel value of the pixel point in the arc area in the historical device image; when it is determined that the comparison result is used to indicate that the pixel median value is greater than or equal to the historical pixel value, determining the first device image as the target device image; when it is determined that the comparison result is used to indicate that the pixel median value is less than the historical pixel value, determining the target device image from the remaining device images in the multiple device images, wherein the remaining device images represent device images other than the first device image in the multiple device images.

[0039] In an exemplary embodiment, the target device image can be determined from the multiple device images by the following steps: inputting the multiple device images into a trained neural network model, and obtaining the target device image output by the neural network model, wherein the neural network model is trained based on historical device images and arc areas marked in the historical device images.

[0040] In an exemplary embodiment, a process for implementing the method of determining the early warning information of the electrical equipment according to the operating temperature of the equipment is further proposed, which specifically includes: when it is determined that the operating temperature of the equipment is greater than or equal to a first temperature threshold, generating the early warning information based on the operating temperature of the equipment; and / or, obtaining the current temperature of the electrical equipment, and when it is determined that the current temperature of the equipment is greater than or equal to the first temperature threshold, generating the early warning information based on the current temperature of the equipment.

[0041] Among them, the above-mentioned first temperature threshold represents the lower limit of the pre-set warning temperature range. If the operating temperature of the equipment is greater than or equal to the first temperature threshold, it means that the electrical equipment is about to overheat, and a warning message needs to be generated to warn the user.

[0042] Optionally, when it is determined that the operating temperature of the device is less than the first temperature threshold, the warning information of the electrical device may be determined based on the target device image. The specific process may refer to the following embodiments.

[0045] like Figure 3 As shown, further, in addition to the above steps S204 to S208, the following steps may also be included:

[0046] Step S301, obtaining the light brightness of the preset image acquisition area, and when it is determined that the light brightness is less than a first brightness threshold, performing fill light on the preset image acquisition area based on an image acquisition device while performing image acquisition on the preset image acquisition area;

[0047] Optionally, in addition to the above step S301, this embodiment may further implement:

[0049] And / or, step S12, obtaining the first device image among the multiple device images, and when determining that the image brightness of the first device image is less than a second brightness threshold, while performing image capture on the preset image capture area, fill light is performed on the preset image capture area based on the image capture device.

[0050] The automatic fill light solution can improve the visibility of the image, thereby improving the user's image viewing experience.

[0051] Optionally, fill light may be performed according to the user's instructions, which may also achieve the purpose of improving the user's image perception, and this application does not impose any restrictions on this.

[0052] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
