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 some, but not all, embodiments of the present application. 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. The reference numbers in the present application are only used for distinguishing the steps in the scheme and are not used for limiting the execution sequence of the steps, and the specific execution sequence is described in the specification.

In the field of electric power technology, in order to ensure electric power and personal safety, the following basic requirements of five prevention are met. The five prevention is to prevent the circuit breaker from being opened and closed by mistake; the isolating switch is prevented from being switched on and off under load; preventing the charged hanging (closing) of a grounding wire (a grounding switch); preventing power transmission with ground wire; prevent the wrong entering into the electrified interval. In the above five preventions, there are four items related to the operation of the disconnecting switch, and if the power technician does not operate the disconnecting switch in place, an electric power safety accident may be caused.

In order to solve the above technical problem, the present application provides a device for monitoring on/off state of a switch, as shown in fig. 1, comprising:

the camera 11 is used for acquiring an image of an area where the target switch is located;

the server 12 is in communication connection with the camera 11 and is used for determining the on-off state of the target switch according to the image and uploading the on-off state of the target switch to a station end system 13;

and the station end system 13 is in communication connection with the server 12 and is used for showing the on-off state of the target switch uploaded by the server 12.

In the apparatus provided in this embodiment, the camera may be a visible light camera or an infrared camera, and the camera is configured to acquire an image of an area where the target switch is located. Preferably, the acquired image includes a complete target switch, or the acquired image includes a part of target switches, and the part of target switches in the image can represent the on-off state of the target switch.

The target switch in this embodiment may be an isolating switch or a knife switch, and may also be another type of switch. The switch includes at least two states, an "on" state and an "off" state, and the switch typically has a different appearance between the "on" state and the "off" state. For example, assuming the target switch is a knife switch, it may be manually pulled up or down by a technician. When the knife switch is in the upward state, the on-off state of the knife switch is in the on state, and when the knife switch is in the downward state, the on-off state of the knife switch is in the off state. The current on-off state of the disconnecting link can be determined by observing the appearance of the disconnecting link.

The camera can be in communication connection with the server in a wired or wireless mode, and the wireless connection mode can be Bluetooth, infrared, WIFI and the like. The camera uploads the acquired image of the area where the target switch is located to the server through communication connection established between the camera and the server, and the server can determine the on-off state of the camera corresponding to the image according to the image uploaded by the camera.

The server can be in communication connection with the station end system in a wired or wireless mode, and after the server determines the on-off state of the target switch, the on-off state of the target switch can be uploaded to the station end system. For example, the server may upload the identification of the target switch and the on-off state of the target switch to the station-side system. The identifier of the target switch may be, for example, a number preset for the target switch, or a position where the target switch is located.

The station-side system can be computer electronic equipment, for example, and the station-side system can display the target switch and the on-off state thereof to a worker in a form or other forms. The station-side system can display the on-off state of the target switch in a picture form through the display equipment, and can also display the on-off state of the target switch in a sound form through the audio equipment.

Fig. 2 is a schematic view of an application scenario of the apparatus provided in this embodiment, and the application scenario includes a disconnecting link 21, a camera 22, a server 23, and a station-side system 24. The area shot by the camera comprises the area where the target switch is located, and then in the actual application process, the camera can acquire the image of the area where the target switch is located. In addition, since the number of switches to be monitored is often multiple, the area actually photographed by the camera may include areas where multiple target switches are located. Preferably, the camera is a high-definition camera for ensuring that the acquired image can clearly show the appearance of the target switch, and further ensuring the accuracy of the on-off state of the target switch determined by the server later.

In the case where the number of switches to be monitored is plural, images of the areas where the plural switches are located may be acquired by using the plural cameras. The area shot by each camera may include an area where one or more target switches are located. According to the processing capacity of the server, the plurality of cameras can be in communication connection with the server or the server group, so that the server or the server group can timely and efficiently process images acquired by the cameras.

When acquiring images of areas where a plurality of target switches are located, the server may first determine identifiers of the target switches, such as positions of the target switches, numbers of the target switches, and the like. Then, the server determines the on-off state of the target switch according to the appearance of the target switch in the image. Then, the server can generate the on-off state results of the plurality of target switches according to the identification of the target switches and the on-off state of the target switches determined according to the images. For example, the server may generate a correspondence relationship of a plurality of target switches with on-off states, such as "target switch a-on state" and "target switch B-off state". In addition, when the on-off state of the target switch cannot be determined according to the image, a state prompt of the target switch can be generated, and a worker is instructed to check the actual state of the target switch, so that potential safety hazards can be found in time, and the target switch is prevented from being in dangerous states such as poor contact and incomplete closing for a long time.

wherein the server 12 comprises an image acquisition module 121 for:

and acquiring an image of an area where the target switch is located in the video.

The camera provided by the embodiment can shoot the image of the area where the target switch is located in multiple modes, for example, a worker can set a shooting period according to actual requirements, when the shooting period is 5 seconds, the camera can shoot the image of the area where the target switch is located every 5 seconds, the shot image can be immediately uploaded to a server to be processed, namely, the server processes the image every 5 seconds, the determined on-off state of the target switch is uploaded to a station end system, and the station end system updates the on-off state of the target switch displayed every 5 seconds. The device provided by the embodiment can periodically monitor the on-off state of the target switch, and the latest on-off state of the target switch is displayed through the station end system, so that a worker can know the on-off state of the target switch in time, and the overall safety and stability of the power equipment are ensured.

The camera provided by the embodiment can also shoot the video of the area where the target switch is located, and upload the shot video to the server in real time for processing. The server may periodically capture images from the video to obtain an image of the area where the target switch is located. For example, the server may intercept an image of an area where the target switch is located from the video every 5 seconds, process the image, and upload the determined on-off state of the target switch to a station end system for display.

Alternatively, the server may intercept the image based on changes in the appearance of the target switch. For example, when a person approaches the target switch, the video image changes, and the server may collect the video image every 1 second and determine the on-off state of the target switch, that is, monitor the on-off state of the target switch at a higher frequency. If the video picture does not change, namely no person approaches the target switch, the video image can be acquired according to a lower frequency, or the video image is not acquired. The scheme provided by the embodiment can acquire the image of the area where the target switch is located from the video shot by the camera. In addition, the acquisition frequency can be adjusted according to whether the video picture changes, the calculation amount of the server can be reduced to a certain degree on the basis of monitoring the on-off state of the target switch, and the waste of calculation resources is avoided.

Subsequently, the server can analyze and recognize the image of the target switch, and further determine the on-off state of the target switch.

According to the scheme provided by the embodiment, the image of the target switch can be separated from the acquired image, and the on-off state of the target switch is identified in a targeted manner, so that the on-off state of the target switch is determined. According to the scheme, the influence of the background in the image on the determined on-off state is reduced, and the accuracy of the determined on-off state of the target switch is improved.
