[0045] In one embodiment, Figure 2 As shown in the figure, a substation fire detection method based on terminal power business edge computing is provided. Figure 1 The intelligent gateway in the example is used as an example to illustrate that the intelligent gateway includes an edge computing unit, including the following steps:

[0046] Step S210: receiving a substation monitoring image sent by an image acquisition device; the substation monitoring image is an image obtained by the image acquisition device by photographing the target substation in real time.

[0047] The image acquisition device may be a video camera, a still camera, etc.

[0048] In the specific implementation, when a fire is detected in a target substation, an image acquisition device can be used to photograph the target substation in real time to obtain a substation monitoring image. Then, the image acquisition device sends the collected substation monitoring image to the intelligent gateway, and the intelligent gateway receives the substation monitoring image sent by the image acquisition device.

[0049] Step S220: Send the substation monitoring image to the edge computing unit.

[0050] Among them, the edge computing unit may refer to a computing unit that enables the intelligent gateway to realize edge computing functions.

[0051] In a specific implementation, after receiving the substation monitoring image, the smart gateway inputs the substation monitoring image into the edge computing unit.

[0052] In step S230, the substation monitoring image is input into the pre-trained flame detection model through the edge computing unit to obtain a flame detection result; the flame detection result is the result obtained by the pre-trained flame detection model marking the flame area in the substation monitoring image.

[0053] The pre-trained flame detection model may refer to a pre-trained yolov3 model.

[0054] In a specific implementation, after the intelligent gateway inputs the substation monitoring image into the edge computing unit, the intelligent gateway, through the edge computing unit, inputs the substation monitoring image into a pre-trained flame detection model. This pre-trained flame detection model then annotates the flame areas in the substation monitoring image to obtain the flame detection results. In practical applications, the flame detection results can include information such as the flame annotated areas.

[0055] Step S240: Generate a fire detection result for the target substation based on the flame detection result; the fire detection result includes at least one of the location of the fire point, the cause of the fire, and the fire severity.

[0056] In a specific implementation, after obtaining the flame detection result, the intelligent gateway can determine at least one of the fire point location, fire cause, and fire level of the target substation based on the flame marked area in the flame detection result, and then generate a fire detection result for the target substation.

[0057] In the above-mentioned substation fire detection method based on edge computing of terminal power business, the substation monitoring image of the target substation is collected in real time by an image acquisition device, and the substation monitoring image is sent to an intelligent gateway with edge computing capabilities; the intelligent gateway inputs the substation image into the edge computing module; the edge computing module is used to input the substation monitoring image into a pre-trained flame detection model to obtain a flame detection result; based on the flame detection result, a fire detection result for the target substation is generated; the fire detection result includes at least one of the fire location, fire cause, and fire level; automated fire inspection is realized, avoiding the consumption of a large amount of human resources.

[0058] In another embodiment, the flame detection result includes a flame marked area. Based on the flame detection result, a fire detection result for a target substation is generated, including: obtaining first position information of the flame marked area in the substation monitoring image, and obtaining second position information of the target substation in the substation monitoring image; determining the fire starting point location of the target substation based on the first position information and the second position information.

[0059] In a specific implementation, when the intelligent gateway generates fire detection results for the target substation based on the flame detection results, the intelligent gateway can obtain the first position information of the flame marked area in the substation monitoring image, and obtain the second position information of the target substation in the substation monitoring image; finally, the intelligent gateway determines the location of the fire point in the target substation based on the relative position relationship between the first position information and the second position information.

[0060] The technical solution of this embodiment obtains the first position information of the flame marked area in the substation monitoring image, and obtains the second position information of the target substation in the substation monitoring image; based on the relative position relationship between the first position information and the second position information, the fire point position of the target substation is accurately located.

[0061] In another embodiment, a fire detection result for a target substation is generated based on the flame detection result, including: determining a flame area image in the substation monitoring image based on the flame marked area; obtaining the flame area in the flame area image, and obtaining grayscale information of the flame area image; and determining the fire level of the target substation based on the flame area and grayscale information.

[0062] In a specific implementation, when generating fire detection results for a target substation based on flame detection results, the intelligent gateway can identify a flame region image within the substation monitoring image based on the flame-annotated area. The intelligent gateway can then obtain the flame area and grayscale information from the flame region image. Finally, the intelligent gateway determines the fire severity at the target substation based on the flame area and grayscale information.

[0063] The technical solution of this embodiment determines the flame area image in the substation monitoring image based on the flame marked area, and obtains the flame area in the flame area image, thereby determining the ignition area of the current fire based on the flame area, and determining the flame intensity of the current fire based on the grayscale information of the flame area image, thereby accurately judging the fire level of the target substation.

[0064] In another embodiment, the fire severity level of the target substation is determined based on the flame area and grayscale information, including: obtaining the ratio between the flame area and the image area of the substation monitoring image, and obtaining the average grayscale value of the grayscale values of each pixel; querying the target fire severity level corresponding to the ratio and the average grayscale value as the fire severity level of the target substation.

[0065] The grayscale information includes the grayscale value of each pixel in the flame area image.

[0066] In a specific implementation, when determining the fire severity level of a target substation based on the flame area and grayscale information, the intelligent gateway can obtain the ratio between the flame area and the image area of the substation monitoring image. Furthermore, the intelligent gateway determines the grayscale value of each pixel in the flame area image from the grayscale information and calculates the average grayscale value of each pixel to obtain the average grayscale value. The intelligent gateway can then query a preset mapping table for the target fire severity level corresponding to this ratio and average grayscale value. Finally, the intelligent gateway uses this target fire severity level as the fire severity level of the target substation.

[0067] The technical solution of this embodiment is to obtain the ratio between the area of the flame area and the image area of the substation monitoring image, and to obtain the average grayscale value of the grayscale values of each pixel; and to query the target fire level corresponding to the ratio and the average grayscale value as the fire level of the target substation. In this way, the fire level of the target substation can be determined in a timely manner.

[0068] In another embodiment, obtaining the flame region area in the flame region image includes: inputting the flame region image into a flame semantic segmentation model to obtain a first flame region in the flame region image; performing guided filtering on the first flame region based on the flame region image to obtain a flame region after guided filtering; and determining the area of the flame region after guided filtering in the flame region image to obtain the flame region area.

[0069] In a specific implementation, when obtaining the flame area from a flame region image, the intelligent gateway may input the flame region image into a pre-trained flame semantic segmentation model. Using this model, the first flame region in the flame region image is determined. The intelligent gateway then performs guided filtering on the first flame region based on the flame region image to obtain a flame region after guided filtering. In practical applications, the intelligent gateway may adjust the contrast of the flame region image to increase the contrast. The intelligent gateway then uses the adjusted flame region image to perform guided filtering on the first flame region to obtain a flame region after guided filtering.

[0070] Finally, the intelligent gateway determines the area of the flame region after the guided filtering in the flame region image to obtain the flame region area.

[0071] The technical solution of this embodiment is to input the flame region image into the flame semantic segmentation model to obtain a first flame region in the flame region image; perform guided filtering on the first flame region based on the flame region image to obtain a flame region after guided filtering, so that the edges of the flame region after guided filtering are sharper, and use the area of the flame region after guided filtering in the flame region image as the flame region area, thereby achieving more accurate determination of the area of the flame region in the flame region image.

[0072] In another embodiment, based on the flame detection result, a fire detection result for the target substation is generated, including: according to the fire point location of the target substation and the fire level of the target substation, searching for the corresponding target fire cause in a preset fire cause database; and using the target fire cause as the fire cause of the target substation.

[0073] In the specific implementation, when the intelligent gateway generates the fire detection results for the target substation based on the flame detection results, after determining the fire point location and the fire level of the target substation, the intelligent gateway can query the corresponding target fire cause in the preset fire cause database according to the fire point location and the fire level of the target substation; finally, the intelligent gateway uses the target fire cause as the fire cause of the target substation.

[0074] The technical solution of this embodiment is to query the corresponding target fire cause in the preset fire cause database according to the fire point location and fire intensity of the target substation, and use the target fire cause as the fire cause of the target substation, so as to quickly determine the fire cause of the target substation based on the fire point location and fire intensity, and thus provide timely reference for users.

[0075] In another embodiment, after the step of generating a fire detection result for a target substation based on the flame detection result, the method further includes: sending the fire detection result to a target master station; the target master station is used to display the fire detection result to a user.

[0076] In a specific implementation, after the intelligent gateway generates a fire detection result for the target substation based on the flame detection results, it can also send the fire detection result to the target master station. In actual applications, the intelligent gateway can send the fire detection result to the target master station via a message queue telemetry transmission protocol for reception by the target master station. After the target master station receives the fire detection result, the target master station can display the fire detection result on a display screen. For example, the target master station can display information such as the current fire point location, fire cause, and fire severity on the display screen, thereby promptly notifying the user of the current fire situation in the target substation.

[0077] The technical solution of this embodiment sends the fire detection results to the target master station for display to the user, thereby promptly notifying the user of the current fire situation in the target substation and allowing the user to go to the scene to perform fire extinguishing operations in a timely manner.

[0078] In another embodiment, Figure 3 As shown in the figure, a substation fire detection method based on terminal power business edge computing is provided. Figure 1 Taking the intelligent gateway in

[15] as an example, the intelligent gateway includes an edge computing unit and the following steps: Step S310: Receive a substation monitoring image sent by an image acquisition device; the substation monitoring image is an image obtained by the image acquisition device taking real-time photos of the target substation. Step S320: Send the substation monitoring image to the edge computing unit. Step S330: Input the substation monitoring image into a pre-trained flame detection model via the edge computing unit to obtain a flame detection result; the flame detection result is the result obtained by the pre-trained flame detection model labeling the flame area in the substation monitoring image; the flame detection result includes the labeled flame area. Step S340: Based on the labeled flame area, determine a flame area image in the substation monitoring image. Step S350: Input the flame area image into a flame semantic segmentation model to obtain a first flame area in the flame area image. Step S360: Perform guided filtering on the first flame area based on the flame area image to obtain a flame area after guided filtering. Step S370: Determine the area of the flame region after the guided filtering in the flame region image to obtain the flame region area, and obtain the grayscale information of the flame region image. Step S380: Determine the fire level of the target substation based on the flame region area and the grayscale information to obtain the fire detection result. Step S390: Send the fire detection result to the target master station; the target master station is used to display the fire detection result to the user.
