Description

Technical Field

[0001] The present application relates to the technical field of visual detection, and particularly relates to a method, device and equipment for detecting the in-place and blockage of a plough-type tripper in a thermal power plant. Background Technique

[0002] The plough-type tripper uses an electro-hydraulic push rod as the power source. During operation, the push rod extends to drive the rod, drives the frame forward to complete the lowering of the plough head, and supports the flat idler group, making the working surface of the belt flat. The lower edge of the plough head fits tightly with the belt surface, and the material on the belt is discharged into the discharge hopper and sent to the corresponding material storage place. After the discharge is completed, the electro-hydraulic push rod is started to retract the drive rod, drive the frame to retreat, lift the plough head, and the variable idler group changes from parallel to trough-shaped to allow the material to pass smoothly. The plough-type tripper is widely used in the coal conveying and stone material conveying systems of thermal power plants.

[0003] In the related art, during the actual operation of a thermal power plant, the conveyor belt system is a key device responsible for conveying fuel and the stone materials required for desulfurization to the operating units of the power plant. In order to ensure that materials can be discharged into different coal bunkers or stone material bunkers, plough-type trippers are mostly used for material separation and batching on the conveyor belt. During the batching process of the plough-type tripper, if the plough-type tripper is not lowered in place, there will be a gap between the conveyor belt and the plough-type tripper, which will cause damage to the belt by the material and also cause the problem of blockage at the material discharge port. After the problem occurs, it will cause material stacking and leakage during transportation, and will also cause irreversible damage to the conveyor belt. In severe cases, the belt will be torn. After the blockage occurs, in addition to affecting normal production operations, it also requires a large amount of manpower to clean up the blockage, resulting in unnecessary cost investment and even indirectly reducing the power generation efficiency.

[0023] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0024] In the related art, in thermal power plants, the in-place and blockage detection of plough-type trippers mostly adopt the methods of manual inspection, physical sensors and remote monitoring by cameras. However, with the continuous development of artificial intelligence, how to achieve intelligent monitoring through effective technical means has gradually become a hot topic. Traditional physical sensors are divided into two categories: contact detection and non-contact detection. However, both of these methods are prone to false touches or false occlusions, resulting in false alarms. At the same time, the detection is not visual, and the staff cannot further confirm the authenticity of the accident, which affects the production efficiency. In addition, under long-term use conditions, the contact-type blockage sensor constantly rubs against the material, which not only affects the detection sensitivity, but also easily causes damage to the sensor. Manual inspection and remote monitoring by cameras also rely on the responsibility of safety officers, and the execution has great randomness.

[0025] Therefore, the in-place and blockage recognition and detection method of the plough-type tripper in the thermal power plant based on machine vision of the present application deploys fixed high-definition camera devices in the monitoring area, and then collects the video of the operation of the plough-type tripper at the monitoring points in real time. By using image recognition algorithms to intelligently monitor the in-place and blockage of the plough-type tripper for the collected point videos, the plough-type tripper can be lowered in place, reducing the overall cost and improving the power generation efficiency.

[0026] The following describes the detection method, device, electronic device, storage medium and program product for the in-place and blockage of the plough-type tripper in the thermal power plant according to the embodiments of the present application with reference to the drawings. Specifically, Figure 1 It is a schematic flowchart of a detection method for the in-place and blockage of the plough-type tripper in the thermal power plant provided by the embodiment of the present application.

[0027] As Figure 1 shown, the detection method for the in-place and blockage of the plough-type tripper in the thermal power plant includes the following steps:

[0028] In step S101, pictures of the in-place and blockage detection of the plough-type tripper at multiple moments and corresponding sample pictures are obtained.

[0029] It can be understood that the embodiments of the present application obtain pictures of the in-place and blockage detection of the plough-type tripper at multiple moments and corresponding sample pictures, so as to calculate the hash values of the detection pictures and sample pictures later.

[0030] In the embodiments of the present application, after obtaining pictures of the in-place and blockage detection of the plough-type tripper at multiple moments and corresponding sample pictures, it includes: using Gaussian filtering to remove the noise of the detection pictures and sample pictures.

[0031] It can be understood that the embodiments of the present application use Gaussian filtering to remove the noise of the detection pictures and sample pictures to make the image quality higher and improve the subsequent calculation efficiency.

[0032] It should be noted that, from the real-time video stream collected by the high-definition camera at the monitoring position of the plough-type tripper, a frame of image to be detected is intercepted every 1 s, and Gaussian filtering is performed to remove noise.

[0033] In step S102, the hash values of the detected image and the sample image are calculated respectively.

[0034] It can be understood that in the embodiments of the present application, the hash values of the detected image and the sample image are calculated respectively, so as to determine the in-place situation or blockage situation of the plough-type tripper based on the hash values subsequently.

[0035] In the embodiments of the present application, calculating the hash values of the detected image and the sample image respectively includes: identifying multiple pixel values of the detected image and the sample image; calculating multiple grayscale averages of the detected image and the sample image, comparing the pixel values with the grayscale averages to obtain multiple comparison results, and calculating the hash value based on the multiple comparison results.

[0036] It can be understood that in the embodiments of the present application, multiple pixel values of the detected image and the sample image can be identified; multiple grayscale averages of the detected image and the sample image are calculated, the pixel values are compared with the grayscale averages to obtain multiple comparison results, and the hash value is calculated based on the multiple comparison results, so as to determine the in-place situation or blockage situation of the plough-type tripper based on the hash values subsequently.

[0037] In the embodiments of the present application, calculating multiple grayscale averages of the detected image and the sample image includes: respectively reducing the detected image and the sample image until they reach a preset size to obtain corresponding multiple first results and second results, and converting the colors of the multiple first results and second results into grayscales of a preset level to obtain corresponding multiple third results and fourth results; calculating the grayscale averages according to the multiple third results and fourth results.

[0038] Among them, the preset size can be a size of 8x8, which can be set according to actual needs and is not specifically limited.

[0039] It can be understood that in the embodiments of the present application, the detected image and the sample image can be respectively reduced until they reach a preset size to obtain corresponding multiple first results and second results, and the colors of the multiple first results and second results are converted into grayscales of a preset level to obtain corresponding multiple third results and fourth results; the grayscale averages are calculated according to the multiple third results and fourth results, so as to compare the pixel values with the grayscale averages to obtain multiple comparison results subsequently.

[0040] Specifically, the hash algorithm process:

[0041] 1. Reduce the size: Reduce the image to a size of 8x8, with a total of 64 pixels. The function of this step is to remove the details of the image, only retain the basic information such as structure, light and shade, and discard the image differences brought by different sizes and proportions.

[0042] 2. Simplify the color: Convert the resized picture to 64 - level grayscale.

[0043] 3. Calculate the average value: Calculate the average grayscale value of all 64 pixels.

[0044] 4. Compare: If the pixel value is greater than the average value, record it as 1; otherwise, record it as 0. There are a total of 64 bits.

[0045] 5. Calculate the hash value: Combine the comparison results of the previous step to form a 64 - bit integer, obtaining the picture fingerprint.

[0046] Compare the calculated result with the in - place hash value and the blocked - material hash value in the sample library to determine whether the plough - type tripper is not in place or blocked.

[0047] In step S103, determine the in - place situation or blocked - material situation of the plough - type tripper based on the hash value, and perform corresponding target operations according to the in - place situation or blocked - material situation.

[0048] It can be understood that in the embodiment of the present application, corresponding target operations are performed according to the in - place situation or blocked - material situation, so that the plough - type tripper is lowered in place, reducing the overall cost and improving the power generation efficiency.

[0049] In the embodiment of the present application, determining the in - place situation or blocked - material situation of the plough - type tripper based on the hash value includes: calculating the ratio of the hash values of the detected picture and the sample picture; when the ratio is less than or equal to a preset threshold, the plough - type tripper is not in place or blocked.

[0050] Among them, the preset threshold can be set according to actual needs and is not specifically limited.

[0051] It can be understood that in the embodiment of the present application, the ratio of the hash values of the detected picture and the sample picture can be calculated; when the ratio is less than or equal to a preset threshold, the plough - type tripper is not in place or blocked, thereby improving the power generation efficiency.

[0052] In the embodiment of the present application, performing corresponding target operations according to the in - place situation or blocked - material situation includes: when the plough - type tripper is not in place or blocked, perform a preset alarm action and update the sample database at the same time, where the sample database includes sample pictures corresponding to the in - place and blocked - material situations of the plough - type tripper at multiple moments.

[0053] Among them, the preset alarm action includes acoustic alarm and / or optical alarm. Among them, the acoustic alarm can be a warning sound emitted by a buzzer, and the optical alarm can be a flashing light, which is not specifically limited.

[0054] It can be understood that in the embodiment of the present application, when the plough - type tripper is not in place or blocked, a preset alarm action can be performed and the sample database can be updated at the same time, so as to improve the operation efficiency.

[0055] According to the detection method for the in-place and blockage of the plough-type tripper in a thermal power plant proposed in the embodiments of the present application, the corresponding hash values are calculated based on the in-place and blockage detection pictures of the plough-type tripper at multiple moments and the corresponding sample pictures. The in-place situation or blockage situation of the plough feeder is determined based on the hash values, and the corresponding target operations are executed according to the in-place situation or blockage situation, so that the plough-type tripper is lowered in place, the overall cost is reduced, and the power generation efficiency is improved.

[0056] Next, Figure 2 The detection method for the in-place and blockage of the plough-type tripper in a thermal power plant of the present application will be elaborated in detail as follows:

[0057] Step 1: Deploy high-definition camera devices in the monitoring area of the plough-type tripper;

[0058] Step 2: Establish an image sample library for the in-place and blockage of the plough-type tripper;

[0059] Upload the in-place and blockage sample pictures of the plough-type tripper, perform Gaussian filtering to remove noise, and calculate the hash vector of the pictures, so as to obtain the image sample library for the in-place and blockage of the plough-type tripper;

[0060] Step 3: Real-time collect the discharge video stream data of the plough-type tripper in the monitoring area;

[0061] Step 4: Intercept a frame of picture to be detected every 1 s from the real-time video stream collected by the high-definition camera at the monitoring position of the plough-type tripper, perform Gaussian filtering to remove noise, and calculate the hash vector of this frame of picture;

[0062] Step 5: Compare the hash value of the picture to be detected with the hash values of the in-place and blockage sample pictures of the plough-type tripper in the sample library, and convert the result into a percentage system. If the result is greater than the set alarm threshold, it means that the plough feeder is not in place or a blockage occurs, and the alarm information is pushed to the server, and the sample library is updated at the same time; otherwise, jump to Step 3.

[0063] In summary, the present application deploys fixed high-definition camera devices in the monitoring area, and then real-time collects the video of the operation of the plough-type tripper at the monitoring point. Through the use of image recognition algorithms for the intelligent monitoring of the in-place and blockage of the plough-type tripper on the collected point video, and through the real-time monitoring of the plough-type tripper on the monitoring conveyor belt, the purpose of detecting the in-place and blockage of the plough-type tripper is achieved.
