Based on the above-mentioned problems and the above-mentioned device architecture, but not limited to the above-mentioned architecture, the method embodiments of the present invention are presented.
The main body of execution of the method of the present embodiment may be a filter cleaning apparatus, which may be a device-independent apparatus capable of performing data processing, and may be carried on the device in the form of hardware or software. The apparatus may be a filter cleaning system. The filter cleaning system is used for example, the interception filter is monitored through the filter cleaning system, when the cleaning condition is reached, the interception filter is cleaned, and when the cleaning condition is reached, the interception filter is cleaned.
Referring to fig. 5, fig. 5 is a flow chart illustrating an exemplary embodiment of a filter cleaning method according to the present invention. The method is applied to a filter cleaning system including an interception filter, the filter cleaning method comprising:
and step S20, monitoring the blocking level of the interception filter when the interception filter is in an interception state.
Among them, an interception filter is a device for filtering foreign substances or harmful substances, such as an interception filter screen or an interception filter film.
Wherein the interception filter comprises the following states: intercepting a filtering state and a cleaning state.
When the interception filter is in an interception filtering state, the rotary driving unit drives the rotary shaft to drive the interception filter to a preset interception position, so that plankton or impurities in water flow are intercepted; when the interception filter is in a cleaning state, the rotary driving unit drives the rotary shaft to drive the interception filter to a preset cleaning position in the enrichment water tank, so that the interception filter is cleaned.
When the interception filter is in an interception filtering state and is used for intercepting plankton or impurities in water flow, the blocking level of the interception filter can be monitored through an image recognition technology.
Specifically, as an embodiment, first, a high-definition camera may be used to collect images of the interception filter, where the collected images should include the whole and partial details of the interception filter, so that various blockage features can be accurately identified during subsequent model training.
And then preprocessing the acquired image, including image cleaning, standardization, enhancement and the like, so as to improve the accuracy of model training.
The occlusion level recognition model may then be trained using a deep learning framework.
The method comprises the steps of acquiring a model, wherein a plurality of image data sets marked with blocking grades of an interception filter are used in training, so that the model can accurately identify blocking conditions of different grades.
And then, performing methods such as cross verification, super parameter adjustment and the like on the blockage level identification model, optimizing the performance of the model, and improving the identification accuracy of the model on different blockage levels.
And finally, deploying the trained blockage level identification model into an actual production environment, and calling the blockage level identification model to carry out blockage level identification by collecting image data of the interception filter in real time.
The blocking grade can be set according to actual production conditions and task requirements. For example, the clogging level may be set to high and low levels.

Wherein, can set up the filter cleaning system start-up time according to actual need.
And when the two conditions of reaching the preset starting time of the filter cleaning system and reaching the preset blocking level of the interception filter are met, cleaning the interception filter.
For example, the preset filter cleaning system start-up time is 8 a.m., the preset blockage level is high, 8 a.m. and thereafter is considered to be the preset filter cleaning system start-up time. If the blocking level of the interception filter reaches an advanced level at 9 a.m., the interception filter is cleaned.
Wherein, as an implementation mode, if the filter cleaning system is arranged in the water treatment device, the water outlet of the water treatment device can be replaced by a waste water collecting device, then the interception filter is directly cleaned, and waste water during cleaning is collected by the waste water collecting device in the process of cleaning the interception filter.
In another embodiment, the interception filter may be moved to a preset cleaning position, and the interception filter may be cleaned at the preset cleaning position.
In another embodiment, when a preset filter cleaning system start-up time is reached and the interception filter reaches a preset blockage level, a worker may be notified while cleaning the interception filter.
Referring to fig. 6, fig. 6 is a schematic diagram illustrating cleaning of an interception filter according to an embodiment of the present invention.
Wherein, drive the interception filter to the preset cleaning position of enrichment basin through the rotation axis in the rotary drive unit, wash the interception filter through spraying the unit, in the sewage inflow enrichment basin that produces in the cleaning process.

And finally, deploying the trained sewage concentration grade identification model into an actual production environment, and calling the sewage concentration grade identification model to carry out sewage concentration grade identification by collecting image data of the enrichment water tank in real time in a cleaning stage.
The sewage concentration level can be set according to actual production conditions and task demands. For example, the sewage concentration level may be set to high and low levels.
Wherein, the cleaning period can be set according to actual needs.
And when the cleaning period is finished and/or the sewage reaches a preset concentration level, the monitoring of the sewage concentration level and the cleaning of the interception filter are finished.
For example, the preset cleaning period is 20 minutes, the preset sewage concentration level is low, and when the cleaning time reaches 20 minutes and then the cleaning period is regarded as ending, the monitoring of the sewage concentration level and the cleaning of the interception filter are ended. Or when the cleaning time is 10 minutes, the concentration level of the sewage reaches a low level, and the monitoring of the concentration level of the sewage and the cleaning of the interception filter are finished.

According to the embodiment of the invention, the blocking grade of the blocking filter is monitored, and when the preset starting time of the filter cleaning system is reached and the blocking filter reaches the preset blocking grade, the blocking of the blocking filter can be timely treated, and the water outlet efficiency is improved. In addition, the embodiment of the invention can intercept plankton and impurities with high precision and without leakage, intercept the real-time working condition of the blocking degree of the filter screen through image sensing, and perform intelligent automatic cleaning and alarming, thereby truly realizing intelligent control and avoiding the waste of water and electric resources in the flushing process.

Plankton often exists in factory water of a running water factory, and causes great threat to the safety of drinking water of citizens. Because the individuals of plankton are too small to be identified by human eyes, the detection of whether plankton exists and the number of plankton in the water plant at present mostly depend on manual microscopic means. The outbreaks of zooplankton have extremely strong randomness and rapidity, the real-time monitoring of the manual microscopic examination is impossible, omission is unavoidable, and the water plant cannot respond rapidly and effectively. Therefore, although there are numerous interception and control means, plankton outbreaks in water plants cannot be controlled in time. The existing equipment for identifying plankton through images only can identify whether plankton exists or not, but cannot identify plankton density, and further has the function of timely cleaning based on blocking degree of an interception filter screen.
