[0051] Compared with the prior art, the beneficial effect of the present invention lies in that, based on the water pressure value in the pure water delivery pipeline as a judgment standard, when the water pressure value is less than or equal to the first preset water pressure value, the water pressure value is too low, and the reason for the low water pressure value is further determined according to the flow rate of the secondary pure water obtained by the pure water flow meter arranged at the output end of the water production main unit membrane group. When the flow rate is less than or equal to the preset flow rate, the water stored in the pure water tank cannot be fully supplied due to the failure to flush the pre-pretreatment mechanism in time; therefore, the preset processing time is lowered to increase the flushing frequency; when the flow rate is greater than the preset flow rate, the pre-pretreatment mechanism and the water production main unit membrane group operate normally. In this case, the speed of the water supply pump is too low to meet the water demand, so the speed of the water supply pump is increased, while ensuring sufficient water supply, thereby effectively improving the filtration efficiency of pure water.

[0052] Furthermore, when the water pressure value is less than or equal to the second preset water pressure value and greater than the first preset water pressure value, the current water supply situation is determined in detail to determine whether the current time node is in the peak water use period. When the absolute value is less than or equal to the preset absolute value, the current time node is in the peak water use period. The analysis module determines whether the minimum water pressure value at the current time node has improved compared with the historical record based on the slope of the calculated time-minimum water pressure value curve at the current time node, and determines it to be qualified when the slope is greater than the second preset slope; when the slope is less than or equal to the second preset slope and greater than the first preset slope, the minimum water pressure value slowly decreases and the trend is within the allowable range, and the speed of the water supply pump is increased to ensure water supply; when the slope is less than or equal to the first preset slope, the decreasing trend of the minimum water pressure value is abnormal, the preset processing time is lowered, and the quartz sand filter tank and the activated carbon filter tank in the pre-pretreatment mechanism are flushed in time to ensure that the water storage capacity of the pure water tank is sufficient, while ensuring the safety of the purified water quality, thereby effectively improving the filtration efficiency of pure water.

[0053] Furthermore, when the absolute value is greater than the preset absolute value, the current time node is not a peak water usage period. In this case, the water pressure value is still lower than the optimal expected value, i.e., the second preset water pressure value. Under the premise that it is not a peak water usage period, the current operating parameters of the water pump are sufficient to ensure the supply of pure water, and the water pressure value is between the first preset water pressure value and the second preset water pressure value. In this case, because the single flushing time for the quartz sand filter tank and the activated carbon filter tank is too short, the pre-pretreatment mechanism has too low processing efficiency for the primary pure water. The preset flushing time is increased to ensure that the materials in the quartz sand filter tank and the activated carbon filter tank are fully flushed, thereby effectively improving the filtration efficiency of pure water while ensuring the safety of the purified water quality.

[0068] Specifically, the flow rate is the volume passing through the pipeline within a preset monitoring time;

[0069] The pre-treatment mechanism includes a raw water pump arranged at the output end of the raw water tank, a plurality of water delivery pipes connected to the output end of the raw water pump, and a multi-way valve motor connected to each water delivery pipe for controlling the raw water delivery route, and the output end of each water delivery pipe is respectively connected to the input end of the quartz sand filter tank, the output end of the quartz sand filter tank, the input end of the activated carbon filter tank and the output end of the activated carbon filter tank;

[0070] The flushing process is that the multi-way valve motor in the pre-treatment mechanism starts to rotate until it reaches the backwashing position, then the raw water pump is connected to the output end of the quartz sand filter tank through the water pipeline, the raw water pump is started to backwash the quartz sand filter tank, and after the backwashing is completed; the multi-way valve motor starts to rotate until it reaches the positive flushing position, then the raw water pump is connected to the input end of the quartz sand filter tank through the water pipeline, the raw water pump is started to positively flush the quartz sand filter tank, and after the positive flushing is completed; the multi-way valve motor starts to rotate and rotates to the reset position, and the flushing process of the quartz sand filter tank is completed;

[0071] After the flushing process of the quartz sand filter tank is completed, the activated carbon filter tank is flushed.

[0072] Specifically, the analysis module determines whether the filtration of pure water meets the preset standard of filtration judgment according to the water pressure value obtained by the pressure sensor set in the pure water delivery pipeline, wherein:

[0073] The first filtering judgment method is that the analysis module determines that the filtration of pure water does not meet the preset standard, and determines the treatment method for the filtration of pure water that does not meet the preset standard according to the flow rate of secondary pure water obtained by the pure water flow meter set at the output end of the water production host membrane group; the first filtering judgment method satisfies that the water pressure value is less than or equal to the first preset water pressure value;

[0074] The second filtering determination method is that the analysis module preliminarily determines that the filtration of pure water does not meet the preset standard, and re-determines whether the filtration of pure water meets the preset standard based on the absolute value; the second filtering determination method satisfies that the water pressure value is less than or equal to the second preset water pressure value and greater than the first preset water pressure value, and the first preset water pressure value is less than the second preset water pressure value;

[0075] The third filtering judgment method is that the analysis module determines that the filtration of pure water meets the preset standards, and controls the pre-pretreatment mechanism to continue to operate using the current operating parameters; the second filtering judgment method satisfies that the water pressure value is greater than the second preset water pressure value.

[0076] Specifically, the preset time node is obtained in the following manner: the analysis module draws a time-water pressure value curve for each detection period based on the water pressure value in each detection period in the acquired historical data, and obtains the minimum water pressure value in each time-water pressure value curve; the analysis module calculates the average value of the time nodes corresponding to each minimum water pressure value, and records the average value as the preset time node;

[0077] The analysis module determines in the second filtering determination mode whether the filtration of pure water meets the preset standard according to the absolute value, wherein:

[0078] The first filtering secondary determination method is that the analysis module preliminarily determines whether the filtration of pure water meets the preset standard, and re-determines whether the filtration of pure water meets the preset standard according to each minimum water pressure value; the first filtering secondary determination method satisfies that the absolute value is less than or equal to the preset absolute value;

[0079] The second secondary filtration judgment method is that the analysis module determines that the filtration of pure water does not meet the preset standards, and adjusts the preset flushing time to a corresponding value according to the difference between the absolute value and the preset absolute value; the second secondary filtration judgment method satisfies that the absolute value is greater than the preset absolute value.

[0080] When the absolute value is greater than the preset absolute value, the current time node is not a peak water usage period. In this case, the water pressure value is still lower than the optimal expected value, i.e., the second preset water pressure value. Under the premise that it is not a peak water usage period, the current operating parameters of the water pump are sufficient to ensure the supply of pure water, and the water pressure value is between the first preset water pressure value and the second preset water pressure value. In this case, because the single flushing time for the quartz sand filter tank and the activated carbon filter tank is too short, the pre-pretreatment mechanism has too low processing efficiency for the first-level pure water. The preset flushing time is increased to ensure that the materials in the quartz sand filter tank and the activated carbon filter tank are fully flushed, thereby effectively improving the filtration efficiency of pure water while ensuring the safety of the purified water quality.

[0081] Specifically, the analysis module draws a time-minimum water pressure value curve according to each minimum water pressure value under the first filtering secondary determination mode, and determines whether the filtering of pure water meets the preset standard of filtering three-time determination mode according to the slope of the calculated time-minimum water pressure value curve at the current time node, wherein:

[0082] The first three-times filtering determination method is that the analysis module determines that the filtration of pure water does not meet the preset standard, and adjusts the preset processing time to a corresponding value according to the difference between the first preset slope and the slope; the first three-times filtering determination method satisfies that the slope is less than or equal to the first preset slope;

[0083] The second three-times filtering determination method is that the analysis module determines that the filtration of pure water does not meet the preset standard, and adjusts the speed of the water supply pump to a corresponding value according to the difference between the second preset slope and the slope; the second three-times filtering determination method satisfies that the slope is less than or equal to the second preset slope and greater than the first preset slope, and the first preset slope is less than the second preset slope;

[0084] The third three-times filtering determination method is that the analysis module determines that the filtration of pure water meets the preset standards, and controls the pre-pretreatment mechanism to continue to operate using the current operating parameters; the third three-times filtering determination method satisfies that the slope is greater than the second preset slope.

[0085] When the water pressure value is less than or equal to the second preset water pressure value and greater than the first preset water pressure value, the current water supply situation is determined in detail to determine whether the current time node is in the peak water usage period. When the absolute value is less than or equal to the preset absolute value, the current time node is in the peak water usage period. The analysis module determines whether the minimum water pressure value at the current time node has improved compared with the historical record based on the slope of the calculated time-minimum water pressure value curve at the current time node, and determines it to be qualified when the slope is greater than the second preset slope; when the slope is less than or equal to the second preset slope and greater than the first preset slope, the minimum water pressure value slowly decreases and the trend is within the allowable range, and the speed of the water supply pump is increased to ensure water supply; when the slope is less than or equal to the first preset slope, the decreasing trend of the minimum water pressure value is abnormal, the preset processing time is lowered, and the quartz sand filter tank and the activated carbon filter tank in the pre-pretreatment mechanism are flushed in time to ensure that the water storage capacity of the pure water tank is sufficient, while ensuring the safety of the purified water quality, thereby effectively improving the filtration efficiency of pure water.

[0086] Specifically, the analysis module determines the treatment method for the pure water filtration not meeting the preset standard according to the flow rate of the secondary pure water obtained by the pure water flow meter set at the output end of the water production host membrane group under the first filtration determination mode, wherein:

[0087] The first processing method is that the analysis module adjusts the preset processing time to a corresponding value according to the difference between the preset flow rate and the flow rate; the first processing method satisfies that the flow rate is less than or equal to the preset flow rate;

[0088] The second processing method is that the analysis module adjusts the rotation speed of the water supply pump to a corresponding value according to the difference between the first preset water pressure value and the water pressure value; the second processing method satisfies that the flow rate is greater than the preset flow rate.

[0089] Based on the water pressure value in the pure water delivery pipeline as the judgment standard, when the water pressure value is less than or equal to the first preset water pressure value, the water pressure value is too low. The reason for the low water pressure value is further determined according to the flow rate of the secondary pure water obtained by the pure water flow meter set at the output end of the water production main unit membrane group. When the flow rate is less than or equal to the preset flow rate, the water stored in the pure water tank cannot be fully supplied due to the failure to flush the pre-pretreatment mechanism in time; therefore, the preset processing time is lowered to increase the flushing frequency; when the flow rate is greater than the preset flow rate, the pre-pretreatment mechanism and the water production main unit membrane group operate normally. In this case, the speed of the water supply pump is too low to meet the water demand, so the speed of the water supply pump is increased. While ensuring sufficient water supply, the filtration efficiency of pure water is effectively improved.

[0090] Specifically, the analysis module records the difference between the calculated absolute value and the preset absolute value as the absolute difference in the second filtering secondary determination mode, and determines the flushing adjustment mode for the preset flushing time according to the obtained absolute difference, wherein:

[0093] The third flushing adjustment method is that the analysis module uses a third preset flushing adjustment coefficient to adjust the preset flushing duration to a corresponding value; the third flushing adjustment method satisfies that the absolute difference is greater than the second preset absolute difference.

[0094] Specifically, the analysis module records the difference between the calculated first preset slope and the slope as the slope difference under the first three-time filtering determination mode, and the analysis module determines the processing adjustment mode for the preset processing time according to the obtained slope difference, wherein:

[0095] The first processing adjustment method is that the analysis module uses the first preset processing adjustment coefficient to reduce the preset processing time to a corresponding value; the first processing adjustment method satisfies that the slope difference is less than or equal to the first preset slope difference;
