Example Embodiment

[0041] Example one:

Example Embodiment

[0042] Such as figure 1 As shown, the method for recognizing the readings of the instrument panel provided in this application, one of its implementations, includes the following steps:

[0043] Step 102: Set a monitoring area on the dashboard, and the monitoring area covers the pointer of the dashboard.

[0044] In one embodiment, the monitoring area can be set according to the range of the meter, such as a sector area. In this embodiment, the monitoring area is a fan-shaped enclosed area drawn according to the normal pointer reading range, such as image 3 As shown, the fan-shaped area A is the monitoring area.

[0045] Step 104: Use the camera to shoot the surveillance video of the dashboard to obtain the video surveillance stream.

[0046] Step 106: Take a screenshot of the video surveillance stream and cut out the dashboard to obtain the first image of the dashboard.

[0047] Step 108: Obtain the reading of the dashboard according to the first image.

[0048] In one embodiment, the...

Example Embodiment

[0058] Embodiment two:

[0059] Such as Figure 4 As shown, an implementation of the instrument panel reading recognition device provided by the present application includes a monitoring module 410, a shooting module 420, an image processing module 430, and a meter reading module 440.

[0060] The monitoring module 410 is used to set a monitoring area on the dashboard, and the monitoring area covers the pointer of the dashboard;

[0061] The shooting module 420 is used for shooting the monitoring video of the dashboard with a camera to obtain the video monitoring stream;

[0062] The image processing module 430 is used to take a screenshot of the video surveillance stream, and to cut out the image of the dashboard to obtain the first image of the dashboard;

[0063] The meter reading module 440 obtains the reading of the instrument panel according to the first image.

[0064] The appearance of the scale of the instrument panel in the dial is an arc of equal divisions, and the starting po...

Abstract

The invention discloses a reading identification method and device of an instrument panel, and the method comprises the steps: setting a monitoring region on an instrument panel, wherein the monitoring region covers a pointer of the instrument panel; shooting a monitoring video of an instrument panel by using a camera to obtain a video monitoring stream; performing screenshot on the video monitoring stream, and performing cutout on the instrument panel to obtain a first image of the instrument panel; and obtaining the reading of the instrument panel according to the first image. According to the embodiment of the invention, the reading of the instrument panel can be automatically obtained according to the first image, the reading of the instrument panel does not need to be obtained in a manual reading mode, maintenance personnel do not need to go to the site for meter reading for maintenance, and the waste of human resources and the risks of falling, scalding, suffocation, stumbling and the like during meter reading are avoided.

Description

technical field [0001] The present application relates to nuclear power equipment, in particular to a reading recognition method and device for an instrument panel. Background technique [0002] The instrument is a very important equipment in nuclear power plants. Relevant professional users can judge the current operating status of the equipment through the instrument data. At present, meters generally include smart meters and conventional meters. Smart meters support communication protocols. Generally, data can be obtained and sent through interfaces such as serial ports or network ports. They can be integrated with the substation comprehensive monitoring system to achieve high-level services. Therefore, the use of smart meters can greatly reduce the maintenance burden of substations. However, conventional instruments are often used more commonly. For the instrument readings of conventional instruments, the data is usually obtained through manual reading. In some places i...
