In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Referring to fig. 1, an embodiment of a first aspect of the present invention provides a switch status monitoring method.
The switch state monitoring method includes but is not limited to the following steps:
step S100, a polling signal is transmitted to the switch 40.
For step S100, in order to perform status detection on the switch 40, the monitoring host 30 transmits a polling signal to the switch 40 through the SNMP protocol to poll the operation status and the port status of the switch 40.
When the lens of the photographing device 10 is not directed to the side of the exchange 40 where the indicator light set is disposed, the angle of the lens of the photographing device 10 needs to be adjusted before successive exchange images are acquired. The monitoring host 30 transmits a lens angle adjustment signal to the photographing apparatus 10. The photographing apparatus 10 is provided with a lens angle adjusting mechanism composed of a motor and a rotating assembly. After receiving the angle adjustment signal, the photographing apparatus 10 controls the lens angle adjustment mechanism to rotate according to the angle adjustment signal, so that the lens faces the side of the switch 40 where the indicator light set is disposed.
Step S200, acquiring a plurality of continuous switch images, wherein the switch images include the indicator light set of the switch 40 after receiving the polling signal.
For step S200, a plurality of switch images including the indicator lamp group of the switch 40 having received the polling signal are continuously photographed by the photographing apparatus 10.
For the switch 40, the normal indicating lamp group includes a first indicating lamp group and a second indicating lamp group, the first indicating lamp group is used for indicating the operation state of the switch 40, and the second indicating lamp group is used for indicating the port state of the switch 40; and the first indicator light group is provided with a plurality of indicator lights, and the second indicator light group is also provided with a plurality of indicator lights. Therefore, the switch image shot by the shooting device 10 contains the first indication lamp group and the second indication lamp group.
And step S300, carrying out image recognition on the switchboard image to obtain coordinate information, color information and time sequence information of each indicator light of the indicator light group.
For step S300, the switch image is preprocessed, and the preprocessing may include denoising, image cropping, and smoothing. Through preprocessing, irrelevant information in the image can be eliminated, useful real information is recovered, the detectability of relevant information is enhanced, and data is simplified to the maximum extent, so that the reliability of feature extraction, image segmentation, matching and identification is improved.
The switch image is image-recognized through an image recognition network of the image processor 20. It should be noted that the image recognition network may adopt a network structure such as a CNN network or an FCNN network.
And cutting the image of the switch to a uniform size, and defining a uniform coordinate system to obtain the normalized coordinate information of each indicator light of the indicator light group. The category of the indicator lamp of the switch 40 is easily obtained from the coordinate information for the image of the same switch 40.
For each indicator light, the indicator light is usually circular, the indicator light occupies a plurality of pixel points in the image of the switch, and each pixel point is displayed through coordinate information. And calculating to obtain the coordinates of the central point corresponding to the indicator lamps according to the coordinate information of the plurality of pixel points of each indicator lamp.
And determining a central pixel point and a plurality of adjacent pixel points adjacent to the central pixel point according to the coordinates of the central point, averaging the RGB value of the central pixel point and the RGB values of the plurality of adjacent pixel points to obtain an average RGB value, and taking the average RGB value as color information corresponding to the indicator light.
It should be noted that the plurality of adjacent pixels are specifically four-adjacent domain coordinates of the central pixel, specifically, an immediately upper pixel, an immediately lower pixel, an immediately left pixel, and an immediately right pixel of the central pixel.
The color information is normalized to facilitate the subsequent identification process. For example, for an indicator light, it typically has a color of colorless, green, orange and red, with colorless indicating extinguished, and colorless, green, orange and red being indicated by 0, 1, 2, 3, respectively. For the average RGB value, although also green, there may be differences, e.g., (0, 258, 0) for one and (1, 253, 0) for the other, both belonging to the green range. When the difference between the color information and the standard color is within a preset threshold range, for example, the difference between (0, 258, 0) and (0, 255, 0) is (0, 3, 0), the variance of the difference is 3, and the difference is within the preset threshold range; the difference between (1, 253, 0) and (0, 255, 0) is (1, 2, 0), the variance of the difference is 2.236, and within the preset threshold range, the two colors of (0, 258, 0) and (1, 253, 0) are normalized and denoted by 1.
For each indicator light, color information obtained from a plurality of switch images is arranged in time sequence to obtain time sequence information. Note that the sampling rate of the time-series information is generally the same as the frame rate of the photographing apparatus 10.
For example, for one indicator light, if the color information in the first switch image is 2, the color information in the second switch image is 0, the color information in the third switch image is 2, and the color information in the fourth switch image is 0, the color information is arranged in time sequence, and the time-series information of the indicator light is 0, 2, 0, 2.
And step S400, judging the state of the switch 40 according to the coordinate information, the color information and the time sequence information to obtain the state information of the switch 40.
For step S400, the following steps are specifically included but not limited to:
classifying the indicator lights corresponding to the coordinate information according to the coordinate information to obtain the category of the indicator lights; since the switch image is normalized according to the coordinate system defined uniformly, the type of the indicator light of the switch 40 can be obtained for the image of the same switch 40 through the coordinate information, and the type of the indicator light can express the purpose of the indicator light;
judging the state of the indicator light according to the category, the color information and the time sequence information of the indicator light to obtain the state information of the indicator light; for example, a port indicator light is used for indicating whether the port a works normally, and the time sequence information is 0, 2, 0, 2, and then the state information of the indicator light is judged to be in a red flashing state;
and judging the state of the switch 40 according to the state information of the indicator lamps of all the indicator lamps to obtain the state information of the switch 40.
In addition, the state information of the switch 40 is compared with the preset alarm condition, and when the state information of the switch 40 meets the alarm condition, an alarm signal is sent. Of course, the status information of the switch 40 may be obtained from the status information of the indicator light, or may be directly compared with the preset alarm condition according to the status information of the indicator light, and when the status information of the indicator light meets the alarm condition, an alarm signal is sent.
For example, if a port indicator is used to indicate whether the port a is working normally and the time sequence information is 0, 2, 0, 2, the status information of the indicator is determined to be red flashing status and the flashing interval is 0.5 s; the state information of the indicator light meets the preset alarm condition and sends out an alarm signal that the port A is abnormal. It should be noted that, because the indication lamps of the switches 40 with different brands and models have different display modes, the alarm rules can be adjusted according to the brands and models of the switches 40 and the monitoring requirements.
The switch state monitoring method can realize automation and intellectualization of monitoring, save labor cost and improve monitoring accuracy; in addition, when the working state of the switch 40 is abnormal or the communication network between the switch 40 and the monitoring host 30 is abnormal, for example, the port of the switch 40 is in a false dead state or the network loop state of the switch 40, the image of the indicator light of the switch 40 can still be identified by the machine vision technology to judge the state of the switch 40, and further judge the state of the network where the switch 40 is located.
