Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flow chart illustrating a method of fault monitoring according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method includes steps 101 to 103.
In step 101, real-time image information of a preset area is obtained, and a fault indicating device is arranged in the preset area. The failure indication means may be, for example, an indicator lamp, or an indication screen or the like for indicating failure information of the monitored device. The means for acquiring the real-time image information may be an image acquisition device such as a camera.
In step 102, a similarity parameter between the real-time image information and preset image information is calculated, where the preset image information is the image information of the preset area when the fault indication device does not perform fault indication. The similarity parameter may be different according to different algorithms used for calculating the similarity, for example, a Simple euclidean distance (Simple euclidean distance) algorithm may be used to determine the similarity between the real-time image information and the preset image information, or a Histogram comparison (Histogram comparison), normalized cross Correlation (normalized cross Correlation), and salient point/area identification (Detectors of local points/areas) or other algorithms may be used to determine the similarity between the real-time image information and the preset image information, and due to the difference in the similarity calculation algorithms used, the similarity parameter may also be different, so when determining whether the real-time image information is similar to the preset image information according to the similarity parameter, the similarity parameter may be determined to be more similar when the similarity parameter is larger, or the similarity parameter may be determined to be less similar when the similarity parameter is smaller, the actual execution should be specifically judged according to the selected algorithm for calculating the similarity.
In step 103, when it is determined that the real-time image information is not similar to the preset image information according to the similarity parameter, extracting fault information according to the real-time image information. After calculating the similarity parameter between the real-time image information and the preset image information, when it is determined that the real-time image information is not similar to the preset image information according to the similarity parameter, it may be determined that the monitored device has a fault, and the fault information is displayed by the fault indicating device in the preset area. Therefore, at this time, the real-time image information containing the fault information needs to be further processed, and the fault information is extracted from the real-time image information, so that the fault information currently displayed by the monitored equipment can be automatically obtained without human inspection.
The method of extracting the fault information based on the real-time image information may be, for example: firstly, determining the area where a fault indicating device for indicating the current fault state is located in the real-time image information, then extracting the state information of the fault indicating device, and finally obtaining the required fault information by judging the specific fault indicated by the state information. In the last step, the method for judging the fault information of the monitored equipment according to the state of the fault indicating device may be to search the fault information corresponding to the state of the fault indicating device in a preset corresponding relationship. For example, the fault indication device may be an LED display screen, and indicate whether the monitored equipment has a fault or not and what the specific fault is when the fault occurs by displaying different text states (normal, fault 1, fault 2, fault 3) and the like; according to the fault monitoring method disclosed by the disclosure, in the process of monitoring the fault of the equipment, firstly, the real-time image information of the LED display screen on the monitored equipment is acquired, and whether the display of the LED display screen in the real-time image information is normal is judged; when the content displayed by the LED display screen is not normal (i.e. the real-time image information is not similar to the preset image information), the real-time image information is further extracted to obtain the content specifically displayed by the LED display screen, for example, the content may be a fault 1, and finally, the fault information corresponding to the fault 1 may be obtained through a preset corresponding relationship including a corresponding relationship between different fault names and actual fault information, for example, the actual fault information indicated by the fault 1 may be a hard disk fault.
By the technical scheme, the area to be monitored and provided with the fault indicating device is subjected to real-time map acquisition, and the similarity is judged according to the image information acquired in real time and the image information in the preset normal state, extracting failure information based on the image information acquired in real time when the image information acquired in real time is not similar to the image information in a normal state in time, therefore, the fault indicating device of the monitored equipment can be monitored in real time without the need of continuous manual inspection of the fault indicating device by managers, the cost of human resources is greatly reduced, and because the non-intrusive monitoring mode, therefore need not develop according to the equipment monitored completely, development cost is low, and the deployment degree of difficulty is little to can extensively promote most needs monitored equipment, the portability is high.
Fig. 2 is a flowchart illustrating a method of extracting fault information from real-time image information in a fault monitoring method according to still another exemplary embodiment of the present disclosure. As shown in fig. 2, the method includes steps 201 to 203.
In step 201, an indicator light region in the real-time image information is identified. When the fault indicating device in the preset area is an indicator light, the method for extracting fault information according to the real-time image information may be to identify the area where the indicator light is located in the real-time image information. Since normally the area of the indicator light is generally circular, in one possible implementation, a Hough Transform (Hough Transform) may be used to identify the circular indicator light area in the real-time image information.
The basic principle of identifying the circular indicator light area by Hough transform is that the duality of points and lines is utilized to determine the circular radius interval according to the equation (x-a) of the circle2+(y-2)2＝r2And mapping the image space to the parameter space through Hough transformation, and changing lines of the image space into the gathering points of the parameter space, thereby detecting whether a circle with a given point radius exists in a given image, and determining the circular area where the indicator lamp is located in the real-time image information.
The method for identifying the indicator light region in the real-time image information may also adopt other identification methods besides hough transform, and the specific identification method is not limited herein.
In step 202, on-off status information for the indicator light zone is identified. After the area where the indicator light is located is identified in the real-time image information, the status information specifically represented in the area needs to be identified. In a possible embodiment, different indicator lights may represent different device status information, for example, when the device is in a normal state, the indicator light for representing that the device is in a normal state is on for a long time, when the device is in a fault state, the indicator lights respectively representing different fault information are turned on according to the actual fault information, for example, when the device is in a hard disk fault, the indicator light representing that the hard disk of the device is in a fault state is turned on, and when the device is in a fan fault, the indicator light representing that the fan of the device is in a fault state is turned on. Therefore, the specific fault information of the monitored equipment indicated by the indicator lamps can be acquired by judging the on-off states of different indicator lamps.
In a possible embodiment, the identifying the on/off status information of the indicator light area includes: and identifying the on-off state information according to the tricolor channel brightness values of the pixel points in the indicator light area. In the three-primary-color principle, most colors can be generated by combining red (R), green (G) and blue (B) according to different proportions, so that the identified indicator light region is analyzed based on the three-primary-color principle, and whether the indicator light in the region is in a turned-on state or a turned-off state is judged according to the RGB three-primary-color channel brightness value of each pixel point in the indicator light region.
The specific determination method may be, for example: when the R component of the pixel points above the preset proportion in the indicator light region is not more than the first preset threshold value, the G component is not more than the second preset threshold value and the B component is not more than the third preset threshold value, the indicator light in the indicator light region is judged to be in an off state, otherwise, the indicator light in the indicator light region is judged to be in an on state. The preset ratio may be, for example, 90%, and the first preset threshold, the second preset threshold, and the third preset threshold may all be the same, or any two of them may be the same, or they may be different from each other, for example, the first preset threshold, the second preset threshold, and the third preset threshold may be simultaneously 100.
TABLE 1
In step 203, fault information is obtained according to the on-off state information and a corresponding relationship, where the corresponding relationship is the corresponding relationship between the on-off state information and the fault information. After the on-off state information of the indicator light area is obtained, the fault information corresponding to the on-off state information can be obtained by searching in a preset corresponding relation according to the on-off state information. For example, the number of indicator lamp regions may be four, which respectively indicate (normal, fault 1, fault 2, and fault 3), when the obtained light-off state information is (light-off ), the fault state corresponding to the light-off state information is found to be fault 1 in the corresponding relationship, that is, the fault information of the monitored device is known to be fault 1, where the fault 1 may be, for example, a hard disk fault or a fan fault, and the like. Wherein a part of the correspondence may be as shown in table 1.
According to the technical scheme, the area representing the circular indicator lamp in the real-time image information is identified through a Hough transform method, and the on-off state information of the area is obtained according to the brightness values of the three primary color channels in the area, so that the fault information of the monitored equipment can be obtained through the on-off state information and the preset corresponding relation, and the fault information of the monitored equipment can be obtained in time without manually monitoring the state of the indicator lamp on site.
In a possible implementation manner, the acquiring real-time image information of the preset area includes: acquiring real-time streaming media data of the preset area; and acquiring the real-time image information from the real-time streaming media data. The method for acquiring the real-time image information of the preset area may be to directly acquire an image of the preset area by using a camera according to a certain period, or may also be to continuously acquire streaming media data from the preset area by using, for example, the camera, and select an image frame from the streaming media data according to a preset rule as the real-time image information.
Fig. 3 is a flow chart illustrating a method of fault monitoring according to yet another exemplary embodiment of the present disclosure. As shown in fig. 3, the method includes step 301 in addition to steps 101 to 103 shown in fig. 1.
In step 301, an alarm is given according to the fault information. After the fault information of the monitored equipment is acquired, alarming can be carried out according to the fault information. The specific alarm manner may be at least one of the following: sending the fault information to preset related personnel; voice broadcasting is carried out on the fault information; and displaying the fault information in a text mode.
The preset related personnel in the sending of the fault information may send the fault information to preset related personnel with corresponding authority in a gsm (global System for mobile communication) short message manner, and the preset related personnel may modify the fault information by setting, for example, the preset related personnel may be set to send the fault information to preset related personnel 1 when the fault information is fault 1, and send the fault information to preset related personnel 2 when the fault information is fault 2, and the like; in addition, the fault information can be sent to preset related personnel in a mail mode, and the fault condition of the monitored equipment can be reflected in time, so that maintenance personnel can maintain the monitored equipment with the fault as soon as possible.
The manner of text display of the fault information may be, for example, display on a fault information display page related to the monitored device.
In one possible embodiment, the method further comprises: and when a response command is not received within a preset time after the alarm is given according to the fault information, controlling the monitored equipment to be powered off or modifying the running state of the monitored equipment so as to protect the running safety of the monitored equipment.
By the technical scheme, after the fault information of the monitored equipment is obtained, corresponding alarm is timely carried out according to the fault information, and certain protection measures are timely carried out on the monitored equipment with the fault when the alarm is not responded, so that the fault of the monitored equipment can be solved as early as possible, and the operation safety of the monitored equipment is protected to a certain extent.
In one possible embodiment, the method further comprises: and storing the fault information into a preset database. When the monitored equipment has a fault, the fault information is stored in a preset database for filing, so that a user can conveniently analyze the fault data of the monitored equipment for a long time.
