Based on the hardware structure, the embodiment of the control method for the resin regeneration conveying process is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the method for controlling the resin regeneration conveying process according to the present invention.
In the first embodiment, the resin regeneration conveying process control method includes the steps of:
step S10, a plurality of monitor images of the resin in the separation column are acquired.
It should be noted that, in general, a plurality of monitoring images of the resin in the separation tower can be obtained through the observation window arranged in the separation tower, in actual operation, a plurality of monitoring images can be obtained through cameras arranged in the observation hole of the grease inlet pipeline of the separation tower, the observation window of the total amount of the resin in the upper part of the separation tower, the observation window of the middle positive and negative resin of the separation tower and the observation window at the bottom of the separation tower, of course, a plurality of monitoring images of the resin in the separation tower can also be obtained through arranging cameras at other positions besides the above positions, and the embodiment does not limit the above.
And step S20, recognizing each monitoring image according to a preset recognition algorithm to obtain the liquid level height of the resin.
It is understood that the preset identification algorithm is a preset image identification algorithm for calculating the height of the resin page through the monitoring image, and the liquid level height is the observed height of the resin in the separation tower, and the liquid level height of the resin is generally obtained by analyzing each monitoring image and performing a conversion operation on image features extracted from each monitoring image through a preset algorithm in a Distributed Control System (DCS).
And step S30, judging whether the resin input is finished according to the liquid level height.
It should be understood that whether the resin is input or not is generally determined by comparing the liquid level height with a preset height, but of course, the current total amount of the resin may be calculated according to the page height, and then compared with the input total amount of the resin to determine whether the resin is input or not, or, whether the resin is input or not may be determined in other manners, which is not limited in this embodiment.
Further, the step S30 specifically includes the following steps:
acquiring the total amount of the resin and the structural parameters of the separation tower, and determining the estimated height of the resin in the separation tower according to the total amount of the resin and the structural parameters of the separation tower;
obtaining a height difference value between the liquid level height and the estimated height;
comparing the height difference value with a preset height difference value threshold value;
when the height difference is larger than the preset height difference threshold value, judging that the resin is not input completely;
and when the height difference value is smaller than or equal to the preset height difference value threshold value, judging that the resin is input completely.
It can be understood that the structural parameters of the separation column include, but are not limited to, structural parameters such as the column internal volume of the separation column, the scale value of the liquid level height in the column, and the size parameter in the column, and after the total amount of the resin is obtained, the estimated height which can be reached by the resin in the separation column can be calculated according to the total amount of the resin and the structural parameters of the separation column, that is, the estimated height of the liquid level formed after the resin is completely conveyed to the separation column and stands still; comparing the liquid level height with the estimated height, wherein the obtained height difference value can be considered as the input of the resin is finished within a certain height difference range, and if the height difference value exceeds the height difference range, the input of the resin is not finished or redundant resin is input; the preset height difference threshold is a preset liquid level height threshold, and the preset height difference threshold may be a height difference threshold determined according to a large amount of experimental data, or a height difference threshold set according to a technician in combination with daily operation experience, or a height difference threshold set in another manner, which is not limited in this embodiment.
And step S40, when the resin input is completed, sending a separation operation starting command to enable the separation tower to perform a separation operation on the resin to obtain a male resin and a female resin.
It is understood that, when the completion of the resin input is detected, a preset separation operation start command may be triggered, and the separation tower may be caused to perform a separation operation on the resin by the separation operation start command, so as to obtain a male resin and a female resin.
And step S50, conveying the male resin to a male tower according to a preset conveying strategy, and conveying the female resin to a female tower.
It should be understood that the preset delivery strategy is a preset delivery strategy for delivering the male resin and the female resin, by which a certain amount of the male resin can be delivered to the male tower and a certain amount of the female resin can be delivered to the female tower according to a predetermined program; in actual operation, a camera can be arranged in the observation window in the middle of the negative tower to obtain a negative resin image, a camera can be arranged in the observation window in the middle of the positive tower to obtain a positive resin image, and the total amount of the negative resin, the total amount of the positive resin and the mixing condition of the positive resin and the negative resin after the subsequent mixing operation in the positive tower are automatically judged by identification software.
Further, after the step S50, the method for controlling the process of resin extracorporeal separation, regeneration and conveyance further includes the steps of:
generating a mixed program control command of the anion resin and the cation resin after the anion resin is input into the cation tower in a program control manner, and obtaining mixed anion resin and cation resin according to the mixed program control command of the anion resin and the cation resin;
acquiring a positive and negative resin image corresponding to the positive and negative resin, and comparing the positive and negative resin image with a preset standard image to obtain an image difference value;
and when the image difference value is greater than or equal to a preset difference value, generating a re-mixing instruction, and re-mixing the male resin and the female resin in the male tower according to the re-mixing instruction according to a preset resin mixing step sequence.
It can be understood that after the anion resin and the cation resin are regenerated by acid and alkali, the anion resin is input into the cation tower in a program control mode, then a mixing instruction is received, and the anion resin and the cation resin are mixed in the cation tower to obtain mixed anion resin and cation resin; and then obtaining a positive and negative resin image, comparing and analyzing the positive and negative resin image with a preset standard image, determining the final mixing condition of the resin, generating a resin re-mixing instruction when the positive and negative resin is not the resin required by the current production, re-mixing the positive resin and the negative resin in the positive tower according to the resin re-mixing instruction until the image difference value between the image formed by the mixed resin and the preset standard image is less than a preset difference value, namely, re-proportioning a new resin can improve the qualification rate of a resin finished product, realize the fine processing of resin production, and improve the production quality and efficiency.
According to the scheme, a plurality of monitoring images of the resin in the separation tower are obtained; identifying each monitoring image according to a preset identification algorithm to obtain the liquid level height of the resin; judging whether the resin is input completely according to the liquid level height; when the resin input is finished, sending a separation operation starting instruction to enable the separation tower to perform separation operation on the resin to obtain a positive resin and a negative resin; the positive resin is conveyed to the positive tower and the negative resin is conveyed to the negative tower according to a preset conveying strategy, so that full automation of fine treatment of the regenerated resin can be realized, operators do not need to monitor and check on the spot, intelligent record management of each set of resin is realized, the health condition of the resin is judged, the labor cost is reduced, the service life of the resin is prolonged, the water production capacity of a mixed bed is improved, and the cost of the regenerated resin is saved.

and step S31, acquiring a resin input image of the resin input port of the separation tower, and determining the total resin input amount according to the resin input image.
It should be noted that the resin input image may be obtained by a camera provided at a resin input port of the separation tower, and the input end point of the resin, that is, the input total amount, may be determined from the resin input image, and specifically, whether all the resin in the mixed bed is fed to the separation tower may be determined according to the color displayed in the pipe when the resin is input.
