[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Combine the following Figure 1A water quality control method of the present invention is described, comprising:

[0046] Step 101, using a water quality detection sensor to collect water quality data of a water area, wherein the water quality data includes ORP data collected by an ORP (Oxidation-Reduction Potential) probe and turbidity information collected by a turbidity sensor;

[0047] This embodiment can be applied to the disinfection and water quality control of water areas such as swimming pools. The feedback water quality data is collected by a water quality detection sensor, such as using an ORP probe to collect ORP data, and using a turbidity sensor to collect feedback turbidity information.

[0048] Step 102, based on the water quality data, a PID (Proportion-Integral-Differential) algorithm is used to control the electrolysis power of the water treatment salt machine equipment and the power used by the ultraviolet lamp to control the water quality of the water area.

[0049] Turbidity information can be used to feedback the turbidity of the water area, which has a great impact on the disinfection effect of the UV lamp. The clearer the water, the better the penetration of the UV lamp and the better the disinfection effect. Therefore, the turbidity information collected by the turbidity sensor is needed to control the power of the UV lamp.

[0050] ORP data is a parameter that measures the relative strength of oxidants and reductants in water or solutions, reflecting the level of electronic activity in the system, that is, the tendency of the reactants to undergo oxidation or reduction reactions. When the ORP value is positive, it indicates that the system tends to undergo oxidation reactions; conversely, a negative ORP value means that the environment is more conducive to the occurrence of reduction reactions.

[0051] The water treatment salt machine equipment mainly controls the chlorine production efficiency by controlling its electrolysis power, thereby adjusting the ORP data of the water area and controlling the water quality.

[0052] The electrolysis power of the water treatment salt machine and the power of the UV lamp are adjusted through PID closed-loop control to achieve intelligent adjustment of water quality. The water quality data determines the adjustment range or target value.

[0053] This embodiment uses water quality data fed back by water quality detection sensors, including ORP data collected by ORP probes and turbidity information collected by turbidity sensors, to adjust the electrolysis power of the water treatment salt machine and the power used by the ultraviolet lamp through PID closed-loop control, thereby realizing intelligent control of the water quality in the water area; an ultraviolet disinfection function is added to the hypochlorous acid disinfection of the water treatment salt machine, and a joint control algorithm of the electrolysis power and the ultraviolet power is used to obtain a faster disinfection speed, a better disinfection effect and a more stable water quality control.

[0054] On the basis of the above embodiment, the PID algorithm is used in this embodiment to control the electrolysis power of the water treatment salt machine equipment and the power used by the ultraviolet lamp, including:

[0055] Determining, according to a preset range in which the turbidity information is located, a turbidity level corresponding to the preset range, wherein the preset range is pre-associated with the turbidity level;

[0056] When the turbidity level is the second level, the ultraviolet lamp and the water treatment salt machine equipment are turned on, and the PID algorithm is used to control the electrolysis power of the water treatment salt machine equipment and the power used by the ultraviolet lamp.

[0057] like Figure 2 As shown, the turbidity information can be divided into three turbidity levels according to the preset range of the turbidity information, such as the first level A1 (clear), the second level A2 (slightly turbid) and the third level A3 (turbid).

[0058] The power used by the UV lamp varies with the turbidity level of the turbidity information. The higher the turbidity level, the lower the power used by the UV lamp. A fixed power used by the UV lamp can be preset for each turbidity level.

[0059] When the turbidity information of the water area is the second level A2 (slightly turbid), turn on the electrolysis of the water treatment salt machine equipment, and turn on the ultraviolet lamp at the same time. Use the PID algorithm to jointly control the electrolysis power of the water treatment salt machine equipment and the power used by the ultraviolet lamp to achieve joint disinfection and quickly improve water quality.

[0060] On the basis of the above embodiment, after determining the turbidity level corresponding to the preset range according to the preset range where the turbidity information is located, the present embodiment further includes:

[0061] When the turbidity level is the first level, the ultraviolet lamp is turned on, the water treatment salt machine equipment is turned off, and the PID algorithm is used to control the power of the ultraviolet lamp so that the collected ORP data is equal to the ORP target value;

[0062] When the turbidity level is the third level, the ultraviolet lamp is turned off, the water treatment salt machine equipment is turned on, and the PID algorithm is used to control the electrolysis power of the water treatment salt machine equipment so that the collected ORP data is equal to the ORP target value.

[0063] like Figure 2 As shown, when the turbidity information of the water area is the first level A1 (clear), only the ultraviolet light is turned on to maximize the disinfection effect.

[0064] When the turbidity information of the water area is the third level A3 (turbid), the water treatment salt machine equipment is turned on for high-power electrolysis, and the ultraviolet lamp is turned off at the same time, so as to achieve different control methods according to different water quality conditions and turbidity levels.

[0065] PID algorithm is a commonly used algorithm in closed-loop control systems. P, I and D are the abbreviations of proportion, integration and differentiation respectively. It is a closed-loop control algorithm that combines proportion, integration and differentiation into one. The feedback loop is introduced to control the system by using the deviation between output (actual value) and input (target value). The specific control process of PID algorithm is as follows: Figure 3 shown.

[0066] For example, in a water treatment salt machine control system, the input target is the ORP target value, the detection device is the ORP probe, the actual measured value is the value detected by the ORP probe, and the error obtained by comparison is the difference between the ORP target value and the measured ORP data. The output value after PID algorithm calculation is used to control the electrolysis power.

[0067] At the same time, the power of the UV lamp is controlled according to the turbidity information fed back by the turbidity sensor, thereby realizing closed-loop control, accurately controlling the water quality ORP, and achieving faster and better disinfection effects.

[0068] On the basis of the above embodiment, in this embodiment, when the turbidity level is the second level, the PID algorithm is used to control the electrolysis power of the water treatment salt machine equipment and the power used by the ultraviolet lamp, including:

[0069] Determining the target power usage of the ultraviolet lamp according to the turbidity information;

[0070] Determining the target electrolysis power of the water treatment salt machine equipment according to the ORP data;

[0071] The PID algorithm is used to control the power usage of the ultraviolet lamp to reach the target power usage, and the electrolysis power of the water treatment salt machine equipment is controlled to reach the target electrolysis power, until the collected ORP data is equal to the ORP target value.

[0072] When the turbidity level is the second level, the target power usage of the ultraviolet lamp is further determined according to the turbidity information. The greater the turbidity information, the smaller the target power usage of the ultraviolet lamp, thereby achieving fine-grained control of the power usage of the ultraviolet lamp.

[0073] The electrolysis of the water treatment salt machine equipment affects the ORP data of the water quality. The target electrolysis power of the water treatment salt machine equipment is determined based on the ORP data. The greater the distance that the ORP data deviates from the normal ORP range, the greater the target electrolysis power of the water treatment salt machine equipment.

[0074] This embodiment collects water quality data in real time, and dynamically adjusts the target usage power of the ultraviolet lamp and the target electrolysis power of the water treatment salt machine equipment according to the water quality data, thereby achieving rapid and accurate control of water quality and improving the disinfection effect.

[0075] On the basis of the above embodiment, in this embodiment, the target power usage of the ultraviolet lamp is determined according to the turbidity information; the target electrolysis power of the water treatment salt machine equipment is determined according to the ORP data, including:

[0076] Obtain the current temperature and current pH value of the water area;

[0077] Compare the preset range corresponding to the first level with the turbidity information, compare the ORP data with the ORP target value, compare the current temperature with the normal electrolysis temperature of the water treatment salt machine equipment, and compare the current pH value with the normal electrolysis pH value of the water treatment salt machine equipment;

[0078] The target usage power of the ultraviolet lamp and the target electrolysis power of the water treatment salt machine equipment are determined according to the comparison result.

[0079] This embodiment takes into account that the temperature and pH value of the water area affect the disinfection effect of the water treatment salt machine equipment, and therefore obtains the current temperature and current pH value of the water area to control the power usage of the ultraviolet lamp and the electrolysis power of the water treatment salt machine equipment.

[0080] The greater the distance that the current turbidity information of the water area deviates from the preset range corresponding to the first level A1 (clear), the worse the disinfection effect of the ultraviolet lamp is, and the smaller the power used by the ultraviolet lamp is.

[0081] The greater the distance between the ORP data and the ORP target value, the worse the water quality is, and it is necessary to increase the power of the UV lamp and the electrolysis power of the water treatment salt machine equipment.

[0082] The greater the distance between the current temperature and the normal electrolysis temperature of the water treatment salt machine equipment, the greater the distance between the current pH value and the normal electrolysis pH value of the water treatment salt machine equipment, the worse the disinfection effect of the water treatment salt machine equipment, and the smaller the electrolysis power of the water treatment salt machine equipment.

[0083] This embodiment comprehensively considers various influencing factors of the power usage of the ultraviolet lamp and the electrolysis power of the water treatment salt machine equipment, thereby achieving precise control of the power usage of the ultraviolet lamp and the electrolysis power of the water treatment salt machine equipment, and improving the disinfection effect.

[0084] Based on the above embodiment, in this embodiment, the target power usage is determined according to the comparison result, including:

[0085] Determine a ratio of a value within a preset range corresponding to the first level to the turbidity information, a first difference between the ORP data and the ORP target value, a second difference between the current temperature and the temperature at which the water treatment salt machine equipment is normally electrolyzed, and a third difference between the current pH value and the pH value at which the water treatment salt machine equipment is normally electrolyzed;

[0086] Calculating the product of the ratio and the maximum power used by the ultraviolet lamp;

[0087] The target power usage is obtained by weighting and adding the product, the first difference, the second difference and the third difference.

[0088] The ratio of the median or maximum value in the preset range corresponding to the first level to the turbidity information can be determined. The larger the turbidity information, the smaller the ratio, the worse the disinfection effect of the ultraviolet lamp, and the smaller the target power usage of the ultraviolet lamp.

[0089] The larger the first difference between the ORP data and the ORP target value, the worse the water quality is, and the larger the target usage power of the ultraviolet lamp and the target electrolysis power of the water treatment salt machine equipment are.

[0090] The greater the second difference between the current temperature and the normal electrolysis temperature of the water treatment salt machine equipment, the greater the third difference between the current pH value and the normal electrolysis pH value of the water treatment salt machine equipment, the worse the disinfection effect of the water treatment salt machine equipment, the smaller the target electrolysis power of the water treatment salt machine equipment, and the larger the target power required of the ultraviolet lamp.

[0091] This embodiment comprehensively considers various influencing factors of the target usage power of the ultraviolet lamp and the target electrolysis power of the water treatment salt machine equipment, realizes the complementary disinfection effects of the ultraviolet lamp and the water treatment salt machine equipment, thereby realizing precise control of the usage power of the ultraviolet lamp and improving the disinfection effect.

[0092] On the basis of the above embodiment, in this embodiment, the target electrolysis power is determined according to the comparison result, including:

[0093] Determine a first difference between the ORP data and the ORP target value, a fourth difference between a value within a preset range corresponding to the first level and the turbidity information, a second difference between the current temperature and a temperature at which the water treatment salt machine equipment is normally electrolyzed, and a third difference between the current pH value and a pH value at which the water treatment salt machine equipment is normally electrolyzed;

[0094] Calculating a weighted sum of the first difference and the fourth difference, and a weighted sum of the second difference and the third difference;

[0095] The difference between the two weighted sums is taken as the target electrolysis power.

[0096] The fourth difference between the median or maximum value in the preset range corresponding to the first level and the turbidity information can be determined. The larger the turbidity information, the larger the fourth difference, the worse the disinfection effect of the ultraviolet lamp, the smaller the target power of the ultraviolet lamp, and the larger the target electrolysis power of the water treatment salt machine equipment.

[0097] The larger the first difference between the ORP data and the ORP target value, the worse the water quality is, and the larger the target usage power of the ultraviolet lamp and the target electrolysis power of the water treatment salt machine equipment are.

[0098] The greater the second difference between the current temperature and the normal electrolysis temperature of the water treatment salt machine equipment, the greater the third difference between the current pH value and the normal electrolysis pH value of the water treatment salt machine equipment, the worse the disinfection effect of the water treatment salt machine equipment, the smaller the target electrolysis power of the water treatment salt machine equipment, and the larger the target power required of the ultraviolet lamp.

[0099] This embodiment comprehensively considers various influencing factors of the target usage power of the ultraviolet lamp and the target electrolysis power of the water treatment salt machine equipment, thereby achieving complementary disinfection effects of the ultraviolet lamp and the water treatment salt machine equipment, accurately controlling the electrolysis power of the water treatment salt machine equipment, and improving the disinfection effect.
