At present, for the detection requirement of the temperature of the electrode plates of the electrolytic cell, besides the electrode plates with abnormal temperature are detected in a manual inspection mode, a thermocouple and a thermal resistance sensor are arranged on the electrolytic cell to measure the temperature of each electrode plate, but the thermocouple and the thermal resistance sensor are made of metal materials, so that the problem of insulation with the electrolytic cell exists, the larger the scale of an electrolytic series is, the more the number of the electrolytic cells is, and the construction requirement cannot be met on site.
In order to solve the problems, the application provides a method for detecting the temperature of an electrolytic cell polar plate, which includes acquiring a first infrared image of the electrolytic cell acquired by an infrared camera, acquiring a temperature value corresponding to a pixel point contained in each polar plate area which is calibrated in advance from the first infrared image, wherein each polar plate area corresponds to one polar plate in the electrolytic cell, and then determining a polar plate temperature value according to the temperature value corresponding to each pixel point in each polar plate area aiming at each polar plate area.
Based on the description, the infrared image of the electrolytic cell collected by the camera bears the temperature data of each pixel point, and coordinates of the pixel points are associated with the position of the polar plate in the image through the polar plate area calibrated in advance, so that the temperature of each polar plate can be accurately positioned according to the temperature data corresponding to the pixel points, and the effective detection of the temperature of the polar plate is realized. When the temperature of the polar plate is positioned, only the polar plate area calibrated in the image is concerned, extra areas (such as an electrolytic tank and an electrolyte area) are not required to be concerned, and the problems of the actual length and width of the polar plate, the edge mechanical deformation of a camera and the image resolution are not required to be considered, so that the detection accuracy is high.
The method for detecting the temperature of the electrode plate of the electrolytic cell proposed by the present application will be described in detail with specific examples.
Fig. 1A is a flow chart illustrating an embodiment of a method for detecting a temperature of an electrolytic cell plate according to an exemplary embodiment of the present application, which can be applied to an electronic device that can interactively communicate with a camera for monitoring the electrolytic cell, the camera having an infrared thermal imaging function. The electrolytic bath in the embodiment of the application comprises a cathode plate and an anode plate, and the number of the cathode plate and the anode plate is the same.
As shown in FIG. 1A, the method for detecting the temperature of the polar plate of the electrolytic cell comprises the following steps:
step 101: and acquiring a first infrared image of the electrolytic cell acquired by the camera.
In one embodiment, since a plurality of groups of electrolytic cells are usually arranged in the workshop, each group of electrolytic cells comprises a plurality of electrolytic cells, the number of the electrolytic cells which can be monitored can be determined according to the field range of the camera, the number of the cameras which need to be arranged can be determined according to the total number of the electrolytic cells in the workshop, and then each camera is fixedly arranged at a proper position of the workshop for fixedly monitoring the electrolytic cells in a certain area.
For example, as shown in fig. 1B, assuming that the camera is a fixed bolt, the field of view ranges from 640 x 512, and 16 cells can be monitored.
Based on the above description, the electronic device may acquire one frame of the first infrared image from each camera at regular time intervals, and since each camera does not need to poll for rotational monitoring, the stability of the acquired temperature data may be ensured, and meanwhile, the validity of real-time detection may also be achieved.
Wherein, the infrared image collected by each camera comprises a plurality of electrolytic cells.
Step 102: and acquiring a temperature value corresponding to a pixel point contained in each electrode plate area which is calibrated in advance from the first infrared image, wherein each electrode plate area corresponds to one electrode plate in the electrolytic tank.
Before step 102 is performed, since the copper on the anode plate is dissolved in the electrolyte and reduced to obtain refined copper on the cathode plate in the electrolytic copper production process, when short circuit occurs between the anode plate and the cathode plate, although the temperature of the anode plate and the cathode plate is increased, the user is concerned about the refined copper quality on the cathode plate, so that the temperature of the cathode plate can be detected only.
Therefore, when the polar plate area is calibrated, only the area of the negative plate in the image can be calibrated, so that the detection efficiency is improved.
In consideration of the problem of the identification degree of naked eyes, the camera can collect the infrared image of the electrolytic cell in the black-hot mode, so that the position of the polar plate can be clearly seen when the polar plate region is calibrated, and a user can conveniently calibrate the position of the polar plate in the image. As shown in fig. 1C, the cell area is an enlarged infrared image, the black area is an electrolyte area, and the white area is a plate.
In one embodiment, the process of calibrating the plate area may be: acquiring and displaying a second infrared image of the electrolytic cell acquired by a camera, detecting a trigger instruction in a display area of the second infrared image, if so, generating a straight line and outputting and displaying the straight line at a trigger position of the trigger instruction, wherein the trigger position is the position of a cathode plate in the second infrared image, then receiving a fine adjustment instruction aiming at the straight line, adjusting the length or the position of the straight line based on the fine adjustment instruction, taking the area occupied by the adjusted straight line in the second infrared image as a pole plate area, and finally correspondingly storing the position information of the cathode plate in the electrolytic cell and the position information of the pole plate area, which are input from the outside.
Wherein, a straight line with a preset width and a preset length can be generated at the triggering position of the triggering instruction. For example, through experimental analysis, it is found that the width of the pixel occupied by the cathode plate in the infrared image collected by the camera is 1 pixel, and the length of the pixel is 20 pixels, and then the generated straight line can be 1 pixel in width and 20 pixels in length. In addition, the length or the position of the straight line is adjusted through the fine adjustment instruction, so that the straight line can completely cover the cathode plate, and the accuracy of the cathode plate area is further ensured.
For example, the position information of the cathode plate in the electrolytic cell can comprise the serial number of the electrolytic cell group, the serial number of the cathode plate in the electrolytic cell and the like. The position information of the polar plate region may be a set of region pixel point coordinates, or certainly may be combination information of the pixel point coordinates of the region vertex and the region width and height.
It will be appreciated by those skilled in the art that the first infrared image and the second infrared image are referred to herein for convenience of description to distinguish between infrared images captured by the camera at different times.
In one example, taking the triggering instruction as a clicking instruction as an example, for each cathode plate, a user clicks at a position of the cathode plate in the second infrared image, the electronic device generates the clicking instruction based on the clicking trigger, and then displays a straight line at the triggering position, so that the straight line completely covers the cathode plate, the user can finely adjust the upper end and the lower end or the position of the straight line, and thus area calibration of one cathode plate is completed.
In the industrial use, the electrolytic cell filled with the electrolyte is divided into an electrified end and a non-electrified end, and the first high temperature generation position is at the electrified end, so that the temperature of the electrode plate at the electrified end of the electrolytic cell can be detected, and the insulating cloth at the electrified end of the electrolytic cell needs to be lifted in order to detect the temperature of the electrode plate.
Based on this, before the area calibration is carried out, the position information of the electrifying end area, which is the area occupied by the electrifying end of the electrolytic cell in the second infrared image, input from the outside can be received, so that when the trigger command is detected, only the trigger command in the electrifying end area needs to be detected.
For example, as shown in fig. 1D, a schematic diagram of plate region calibration in the current-carrying end region is shown, where a black box is the current-carrying end region, and a white vertical line in the box is the calibrated plate region.
Step 103: and determining a polar plate temperature value according to the temperature value corresponding to each pixel point in each polar plate region.
In one embodiment, since the user is concerned about the abnormal increase of the plate temperature, for each plate region, the highest temperature value may be selected as the plate temperature value from the temperature values corresponding to the pixel points in the plate region.
In another embodiment, in order to avoid the situation that the temperature value of the noise point is very high and the difference between the temperature value of the noise point and the temperature value of other pixel points in the polar plate region is very large, for each polar plate region, the average temperature value of the temperature values corresponding to the pixel points in the polar plate region may be counted, and the average temperature value is used as the polar plate temperature value.
It should be noted that after the pole plate temperature value of each pole plate region is obtained, the position information of the cathode plate corresponding to each pole plate region in the electrolytic cell and the pole plate temperature value corresponding to each pole plate region can be output, so that a user can check the current temperature condition of the pole plate in the electrolytic cell in a workshop.
It should be further noted that a temperature threshold may also be preset, and only the position and temperature value of the pole plate exceeding the temperature threshold are prompted, that is, whether the temperature value of the pole plate corresponding to the pole plate area exceeds the preset threshold may be determined for each pole plate area, and if the temperature value of the pole plate corresponding to the pole plate area exceeds the preset threshold, the position information of the cathode plate corresponding to the pole plate area in the electrolytic tank and the abnormal prompt of the temperature value of the pole plate corresponding to the pole plate area are output.
In the embodiment of the application, a first infrared image of an electrolytic cell acquired by an infrared camera is acquired, a temperature value corresponding to a pixel point contained in each polar plate region which is calibrated in advance is acquired from the first infrared image, each polar plate region corresponds to one polar plate in the electrolytic cell, and then the polar plate temperature value is determined according to the temperature value corresponding to each pixel point in the polar plate region aiming at each polar plate region.
Based on the description, the infrared image of the electrolytic cell collected by the camera bears the temperature data of each pixel point, and coordinates of the pixel points are associated with the position of the polar plate in the image through the polar plate area calibrated in advance, so that the temperature of each polar plate can be accurately positioned according to the temperature data corresponding to the pixel points, and the effective detection of the temperature of the polar plate is realized. When the temperature of the polar plate is positioned, only the polar plate area calibrated in the image is concerned, extra areas (such as an electrolytic tank and an electrolyte area) are not required to be concerned, and the problems of the actual length and width of the polar plate, the edge mechanical deformation of a camera and the image resolution are not required to be considered, so that the detection accuracy is high.
