Referring to fig. 1, some embodiments of the present application provide an ultraviolet light source control method of a water purification system, which is applied in the water purification system and used for dynamically adjusting the brightness of an ultraviolet light source to perform water purification, the water purification system includes a water flow sensor, a temperature sensor, an alarm module and a heat dissipation module, the water flow sensor is used for detecting water flow velocity information, the heat dissipation module is used for adjusting heat dissipation power according to the light source temperature information detected by the temperature sensor so as to dissipate heat of the ultraviolet light source, and the alarm module is used for detecting failure states (such as failure states of start-up, overvoltage, overcurrent, overtemperature and the like) of the ultraviolet light source, the water flow sensor and the heat dissipation module;
the ultraviolet light source control method of the water purification system comprises the following steps:
s1, acquiring water flow velocity information;
s2, determining purification area information according to the water flow velocity information;
and S3, adjusting power information for controlling the brightness of the ultraviolet light source according to the purification area information.
Specifically, the water purifying system is a treatment system for purifying a water body, and ultraviolet light is released to the water body through an ultraviolet light source formed based on an LED for sterilization and disinfection treatment, wherein the water body is an object to be treated of the water purifying system and can be divided into drinking water, tap water, beverage and the like according to different application scenes.
More specifically, for continuous production objects such as beverage and tap water, the water purification system needs to perform water purification treatment on the water body in the continuous flowing process of the water body, as shown in fig. 2, for the water purification treatment of the objects, quartz glass is generally arranged at a turning position of a water body flowing pipeline, and an ultraviolet light source which irradiates towards the direction opposite to the flowing direction of the water body is arranged outside the quartz glass to continuously disinfect the flowing water body in the pipeline; the water flow velocity information is the flow velocity of the water in the pipeline towards one side of the ultraviolet light source, and the purifying area information is an effective purifying area generated by the irradiation range of the ultraviolet light source in the pipeline, namely an area with expected purifying capacity; it should be noted that, the light emitting power of the ultraviolet light source is related to the size of the purifying area information, the larger the light emitting power is, the larger the brightness (i.e. the light emitting intensity) of the generated ultraviolet light source is, so that the larger the effective irradiation distance of the ultraviolet light source in the pipeline is, and the larger the purifying area information is; the continuously flowing water body continuously passes through the effective purifying area, and the purifying treatment time of the purified water body corresponds to the retention time in the effective purifying area, so that the flow velocity information of the water body influences the purified time of the water body.
More specifically, an excessively small effective purification area may cause incomplete water purification treatment, and an excessively large effective purification area may cause unnecessary power consumption of an ultraviolet light source to increase treatment cost although the water can be effectively purified, so that the ultraviolet light source control method of the water purification system according to the embodiment of the application determines the size of the effective purification area required for water purification based on the water flow rate information, calculates the luminous intensity of the ultraviolet light source required for generating the effective purification area according to the purification area information representing the size of the effective purification area, and further determines and adjusts the power information of the ultraviolet light source, so that ultraviolet light generated based on the power information can effectively purify the water.
According to the ultraviolet light source control method of the water purification system, when the purification system performs water purification treatment, the water flow rate information is dynamically obtained in real time, the purification area information required by the water purification treatment is determined according to the water flow rate information, and further the power information for controlling the brightness of the ultraviolet light source is dynamically adjusted so that the ultraviolet light source can generate ultraviolet rays matched with or completely covering the purification area information, and therefore the water can be effectively purified, and meanwhile the power consumption cost is controlled.
More specifically, the water flow sensor may be an existing liquid water flow sensor disposed in the pipe and located at an outlet end of a last station of the purifying process (a station determined with reference to a different process flow of a different process object, such as an outlet end of a beverage stirring station) or at a front side of the effective purifying area, for detecting a flow rate of water in the pipe to the effective purifying area, that is, acquiring water flow rate information; the temperature sensor is arranged on the ultraviolet light source or on the back side of the ultraviolet light source, and the acquired light source temperature information is the heating temperature of the ultraviolet light source.
More specifically, when the ultraviolet light source is in operation, the service life of the ultraviolet light source is affected by the too high temperature, so that the heat dissipation module in the water purification system can adjust the heat dissipation power according to the light source temperature information detected by the temperature sensor so as to dissipate heat of the ultraviolet light source, and therefore, in some preferred embodiments, the method of the embodiment of the application further comprises the steps of:
under the condition that the ultraviolet light source is started, radiating power information is obtained according to the light source temperature information, and the radiating module is controlled to radiate the ultraviolet light source based on the radiating power information.
Specifically, the embodiment enables the water purification system to integrate a heat dissipation function, can automatically adjust the heat dissipation effect according to the actual use temperature of the ultraviolet light source, and can effectively and reasonably reduce the operation temperature of the ultraviolet light source, thereby prolonging the service life of the ultraviolet light source.
In some preferred embodiments, the water purification system further comprises a status light module, wherein the status light module comprises a plurality of functional status lights for displaying the water purification treatment status of the water purification system, such as a starting status light for displaying whether the water purification treatment is started, and an intensity status light for displaying the power information of the ultraviolet light source.
More specifically, the status light module preferably includes the alarm module described above for alerting a fault to effect an alarm via a fault status light.
In some preferred embodiments, the method of the present embodiments further comprises the steps of:
and under the condition that the ultraviolet light source is turned on, detecting whether the ultraviolet light source has faults according to the heat radiation power information and the power information of the ultraviolet light source.
Specifically, in general, the higher the running power of the ultraviolet light source is, the faster the heat generation rate is, and the heat dissipation power information of the heat dissipation module needs to be correspondingly increased to dissipate the heat of the ultraviolet light source, so that the heat dissipation power information and the power information of the ultraviolet light source have a linear relation in positive correlation.
In some preferred embodiments, the ultraviolet light source is activated when the water flow rate information is non-zero.
Specifically, when the water purification system needs to perform purification treatment, water body flows in a pipeline along a single direction under the action of a power device of the water purification system, and the flow velocity information of the water body generated by flowing along the flowing direction is a positive value, so that the flow velocity information of the water body is not zero, which means that the water purification system needs to perform water purification treatment on the water body, and then the ultraviolet light source is controlled to be turned on for performing water purification treatment; when the water purification system does not need to carry out purification treatment, the water body is generally still in the pipeline, so that the water flow rate information is a non-positive value, which means that the water purification system does not need to carry out water purification treatment on the water body.
In some embodiments, the purifying area information may be set based on the water flow rate information and a preset mapping relationship, that is, the step of determining the purifying area information according to the water flow rate information includes:
s21, determining purifying area information according to the water flow velocity information and a preset mapping relation.
Specifically, in this embodiment, the mapping relationship is a pairing relationship of the water flow velocity information and the purification area information, and the water flow velocity information may be matched with the purification area information with a suitable size based on the mapping relationship, where the mapping relationship may be a mapping table or a mapping function; the method provided by the embodiment of the application can rapidly acquire the proper purification area information according to the water flow velocity information based on the mapping relation.
The embodiment is equivalent to the conversion of the purification area information with proper size under the determined purification time length, and is particularly suitable for being regulated and used for specific water bodies; however, there is a certain difference in the purifying parameters required by different types of water bodies, if different purifying time periods are required for purifying, the purifying process needs to determine the purifying time period according to the type of the water body, and then the size of the purifying area information is dynamically calculated based on the purifying time period, so in some preferred embodiments, the step of determining the purifying area information according to the flow rate information of the water body includes:
s21', determining purifying area information according to the water flow rate information and preset purifying time length information.
Specifically, the purifying duration information is time data input in advance according to the type of the water body, and characterizes the retention time of the water body in the purifying area information, so that the purifying area information actually required for purifying the water body can be calculated according to the water body flow rate information and the purifying duration information generated by the actual flowing of the water body, and the method provided by the embodiment of the application can reasonably allocate the power information of the ultraviolet light source according to the purifying area information.
More specifically, the purification duration information may be a direct input value, that is, time data which is determined according to water characteristics (water type, water temperature state, pretreatment process) and can be directly input into the water purification system, or one of a plurality of time data which is stored in the water purification system in advance and is called up based on a response instruction.
In some preferred embodiments, the step of adjusting power information for controlling brightness of the ultraviolet light source according to the purge region information includes:
and S31, adjusting power information according to the purification area information and the water ultraviolet transmittance information, wherein the water ultraviolet transmittance information is obtained according to the water type information or detection.
Specifically, the ultraviolet rays can generate more obvious attenuation when being transmitted in the liquid, and in the embodiment of the application, the area of the ultraviolet rays before the ultraviolet rays are attenuated to the intensity required by water body purification is an effective purification area, namely the area corresponds to the purification area information; the water ultraviolet light transmittance information is the transmittance of the ultraviolet light transmitted in unit distance in the corresponding water, the light transmittance information directly characterizes the reserved intensity of the ultraviolet light transmitted in unit distance in the corresponding water and indirectly characterizes the attenuation condition of the ultraviolet light transmitted in unit distance in the corresponding water, therefore, the effective purifying area of the ultraviolet light in the water can be calculated based on the water ultraviolet light transmittance information and the luminous intensity of the ultraviolet light source, otherwise, the luminous intensity of the ultraviolet light source required can be calculated based on the purifying area information and the water ultraviolet light transmittance information, and the luminous intensity of the ultraviolet light source and the power information are in a linear relation, so that the method can adjust the power information according to the purifying area information and the water ultraviolet light transmittance information, and the effective purifying area generated by the ultraviolet light source in the water can meet the purifying requirement.
More specifically, the water ultraviolet transmittance information may be a direct input value, that is, transmittance data determined according to water characteristics (water type, water temperature state, pretreatment process) that can be directly input into the water purification system, or one of a plurality of transmittance data stored in the water purification system in advance and retrieved based on a response instruction.
More specifically, the ultraviolet light propagates in different components in water bodies in unit distance and has attenuation phenomena of different degrees, so that the ultraviolet light transmittance information of the water bodies needs to be set according to the characteristics of the water bodies, the proper ultraviolet light transmittance information of the water bodies can be called from the existing database based on the type information of the water bodies, and the water bodies can be detected to obtain the ultraviolet light transmittance information of the water bodies, so that the ultraviolet light transmittance information of the water bodies can accurately reflect the attenuation condition of the ultraviolet light in the current water bodies, and the accuracy of power information regulation is ensured.
More specifically, the ultraviolet intensity in the effective purification area satisfies the intensity required for purification, and therefore, the process of calculating the power information is essentially to calculate the ultraviolet light emission intensity at the ultraviolet light source based on the minimum ultraviolet intensity required for purification and the purification area information and the water ultraviolet transmittance information, and then to control based on the ultraviolet light emission intensity converted power information, and therefore, the step of adjusting the power information based on the purification area information and the water ultraviolet transmittance information preferably includes:

s32, compensating and adjusting the power information according to the using time of the ultraviolet light source and the preset compensation proportion so as to control the brightness of the ultraviolet light source.

More specifically, the attenuation information is an attenuation rate of ultraviolet light with respect to a unit amount of dissolution of different solutes, and may be an attenuation rate relation table or an attenuation rate relation function.

s22, purifying area information is increased based on a preset area compensation proportion.
Specifically, when the water body flows, fluctuation exists in the same flow surface, the measured water body flow velocity data can not necessarily effectively represent the flow velocity on the flow surface, and in order to ensure that the water body can be effectively purified, the method provided by the embodiment of the application sets the area compensation proportion to slightly increase the purification area information so as to ensure that the water body can be effectively purified.
More specifically, in the embodiment of the present application, the area compensation ratio is preferably 1.1 to 1.3 times.

s311', acquiring purifying distance information according to the purifying area information;
s312', a purifying distance change function related to power information is called according to the ultraviolet light transmittance information of the water body;
s313', adjusting the power information according to the purge distance information and the purge distance variation function.
Specifically, as shown in fig. 2, in the continuous purification treatment of the water body, the water body flows in a straight line along the pipeline in the effective purification area, so that the effective purification area is approximately a cylindrical area, and the purification area information can be directly characterized by using the purification distance information, namely, the flow length of the water body in the pipeline in the purification treatment process is used for determining.
More specifically, in the embodiment of the present application, the purification system stores purification distance change functions (i.e., a relation curve between the power information and the purification distance, which may be determined or obtained based on multiple experiments) corresponding to various pieces of water ultraviolet transmittance information, and after the water ultraviolet transmittance information is determined, the method of the embodiment of the present application may invoke the purification distance change function most similar to the purification distance change function related to the power information according to the water ultraviolet transmittance information, so as to reflect the change relation between the purification distance information and the power information under the corresponding water ultraviolet transmittance information, so that step S313' may directly dynamically adjust the power information based on the purification distance information under the guidance of the corresponding purification distance change function, so as to implement dynamic and continuous adjustment of the power information.
More specifically, the purifying distance information is preferably the length of purifying area information near the edge of the inner wall of the pipeline, as shown in fig. 2, the ultraviolet light source emits light with the characteristic of longer illumination distance in the middle, and in order to ensure better purifying treatment effect, the method of the embodiment of the application uses the length of purifying area information near the edge of the inner wall of the pipeline with smaller illumination distance as the purifying distance information.

and acquiring a flow velocity change curve in preset time, and determining the maximum flow velocity of the flow velocity change curve as water flow velocity information.
Specifically, the running speed of the water body has certain fluctuation, and the load of the running mode of continuously analyzing and continuously adjusting the power information is larger, so the method of the embodiment of the application preferably obtains the flow speed change curve of the water body flow speed information at intervals, takes the maximum flow speed in the interval time as the water body flow speed information and takes the maximum flow speed as the regulation standard of the power information, thereby effectively reducing the running load and ensuring that the ultraviolet light source can generate an effective purification area meeting the requirement of water body purification under the power information.

and S4, compensating and adjusting the power information according to the water temperature information.
Specifically, the water body has different purification requirements at different temperatures, mainly represented by different purification capacities of ultraviolet rays at different temperatures, the optimal adaptive temperature of the purification capacities of the ultraviolet rays is 20-40 ℃, and the purification capacities of the ultraviolet rays are influenced by the fact that the purification treatment time of the ultraviolet rays is required to be properly prolonged due to the fact that the ultraviolet rays are too high or too low in temperature, so that the effective purification area is required to be changed according to the water body temperature information, the power information is compensated and adjusted, and the purification time of the water body is further changed; preferably, the compensation multiplying power of step S4 is 1 when the water temperature information is within 25-35 ℃, and the compensation multiplying power is increased by 0.1-0.3 when the water temperature information is above 35 ℃ or below 25 ℃ and 5 °.

Specifically, the water flow sensor is arranged at the outlet end of the last station of the effective purifying area, the water flow rate is delayed to be reflected at the effective purifying area after being changed, and the power information is set to be in delay adjustment, so that the change of the water flow rate information can be matched more accurately to purify the water.
More specifically, the delay value of the delay behavior may be a preset value, or may be set based on the water flow velocity information and the distance between the water flow sensor and the ultraviolet light source, where the time when a part of the water with a changed flow velocity enters the effective purification area may be more accurately determined.
In some preferred embodiments, the ultraviolet light source has a luminance of light emission intensity after penetration of quartz glass; the ultraviolet light has certain attenuation rate when penetrating through the quartz glass, so the ultraviolet light luminous intensity of the water body which is actually purified is the intensity of the ultraviolet light after penetrating through the quartz glass.
