Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Fig. 1 is a flowchart of a fault monitoring and alarming method for an electrical device according to an embodiment of the present application.
As shown in fig. 1, the fault monitoring and alarming method provided by this embodiment is applied to a distribution room, where at least one piece of power equipment is installed, where the power equipment includes, but is not limited to, a high-voltage switch cabinet, a low-voltage switch cabinet, a UPS cabinet, a control cabinet, a battery pack, and the like, and a plurality of image capturing devices are installed at different positions in the distribution room. Specifically, the fault monitoring and alarming method comprises the following steps:
and S1, acquiring a real-time image of the monitored electric equipment.
The side and bottom of the electrical equipment installed in the electrical distribution room are blocked, so the images are the front image, the back image and the top image of the electrical equipment, or parts thereof. And the real-time image is a common image of visible light, and can also be an infrared image or an ultraviolet image.
And S2, processing the real-time image based on the image recognition algorithm.
The state parameters of the monitored electric power equipment can be obtained by processing the real-time images by using an image recognition algorithm. The image recognition algorithm can be understood as a pre-trained image recognition model, which is obtained by training a deep neural network through a large number of pre-labeled samples. During training, firstly, a large number of historical images of corresponding power equipment are collected and labeled, namely, the corresponding historical images and real-time corresponding state parameters are labeled correspondingly, then, the historical images are distributed into training samples and verification samples, and a pre-constructed deep neural network is trained through the samples, so that the image recognition model is obtained.
And S3, judging whether the monitored equipment has a fault.
After obtaining the state parameter of the corresponding monitored electric power equipment, the state parameter is determined based on a corresponding standard or a preset threshold, for example, if the state parameter is the temperature of the monitored electric power equipment, it may be determined that the monitored electric power equipment has a fault when the temperature exceeds the threshold set by extraction. After judging that this monitored power equipment breaks down, send alarm information through self equipment, for example voice alarm information or audible and visual warning, also can send alarm information to master control equipment through network or data line to make the operation and maintenance personnel in time obtain this alarm information.
Since the monitored electric equipment may generate flame, smoke, arc light or generate excessive temperature due to fault, the alarm information here may be a flame alarm, smoke alarm, arc light alarm or heat abnormal alarm, so as to remind the operation and maintenance personnel that combustion, arc or over-temperature fault occurs in the corresponding electric equipment.
According to the technical scheme, the method is applied to a power distribution room provided with at least one monitored power device, and particularly, the method is used for acquiring a real-time image of each monitored power device based on image acquisition equipment installed in the power distribution room; processing the real-time image based on an image recognition algorithm to obtain state parameters of the monitored electric power equipment; and determining whether the monitored equipment has a fault according to the state parameters, and sending alarm information when the monitored equipment has the fault. Because this scheme reports to the police based on real-time image, rather than send alarm information after flame, smog and heat produce certain accumulation, the harm generally does not form this moment, so can in time protect it when power equipment breaks down, avoid producing the essence harm.

Specifically, the fault monitoring and alarming device comprises an image acquisition module 10, an image processing module 20 and an alarm execution module 30.

And the real-time image is a common image of visible light, and can also be an infrared image or an ultraviolet image.
And the signal input end of the image processing module is connected with the signal output end of the image acquisition module and is used for receiving the real-time image and processing the real-time image based on an image recognition algorithm.
The image processing module can obtain the state parameters of the monitored electric power equipment by processing the real-time images by using an image recognition algorithm, and outputs the state parameters to the alarm execution module through the signal output end of the image processing module.
The image recognition algorithm can be understood as a pre-trained image recognition model, which is obtained by training a deep neural network through a large number of pre-labeled samples. During training, firstly, a large number of historical images of corresponding power equipment are collected and labeled, namely, the corresponding historical images and real-time corresponding state parameters are labeled correspondingly, then, the historical images are distributed into training samples and verification samples, and a pre-constructed deep neural network is trained through the samples, so that the image recognition model is obtained.
And the signal input end of the alarm execution module is connected with the signal output end of the image processing module and used for judging whether the monitored equipment breaks down or not according to the state parameters.
After obtaining the state parameter of the corresponding monitored electric power equipment, the state parameter is determined based on a corresponding standard or a preset threshold, for example, if the state parameter is the temperature of the monitored electric power equipment, it may be determined that the monitored electric power equipment has a fault when the temperature exceeds the threshold set by extraction. After judging that this monitored power equipment breaks down, send alarm information through self equipment, for example voice alarm information or audible and visual warning, also can send alarm information to master control equipment through network or data line to make the operation and maintenance personnel in time obtain this alarm information.
Since the monitored electric equipment may generate flame, smoke, arc light or generate excessive temperature due to fault, the alarm information here may be a flame alarm, smoke alarm, arc light alarm or heat abnormal alarm, so as to remind the operation and maintenance personnel that combustion, arc or over-temperature fault occurs in the corresponding electric equipment.
