Description

Technical Field

[0001] The present invention belongs to the technical field of salt chlorine generation, and particularly relates to a salt chlorine generation control method, system and salt chlorine generator. Background Art

[0002] The statements in this part only provide background technical information related to the present invention, and do not necessarily constitute prior art.

[0003] A salt chlorine generator is a device for water disinfection using the electrolysis principle. It mainly generates sodium hypochlorite by electrolyzing brine, which is used to kill bacteria, algae and pollutants in water, and is widely used in the field of swimming pool water treatment. A complete salt chlorine generator usually includes a power supply, a controller, an electrolysis device and a water flow sensor. For a salt chlorine generator to work properly, it usually also requires a water circulation pipeline and a circulation pump. After the circulation pump works, the water in the swimming pool flows through the electrolysis device through the pipeline, thereby electrolyzing to produce chlorine disinfection components. During use, the user directly dissolves salt in the pool water. The electrolysis device is connected in series to the circulating water pipeline. When the circulation pump works, water is sent into the water inlet of the electrolysis device and flows out through the water outlet after being processed by the electrolysis device. The salt chlorine generator system outputs a certain voltage to the electrolysis device through the controller, and the electrolysis device electrolyzes to generate chlorine disinfection components to kill bacteria and pollutants in the pool water.

[0004] The following conditions are required to maintain the optimal working state of the salt chlorine generator: it is necessary to maintain a rated salt concentration, provide an appropriate voltage, and the electrolysis plates in the electrolysis device also need to work at an appropriate temperature, otherwise the service life of the electrolysis plates will be reduced.

[0005] Therefore, the existing salt chlorine generators usually have the following disadvantages:

[0006] There are potential safety hazards. When the salt chlorine generator works, a certain water flow needs to be maintained in the electrolysis device. This parameter has a limited upper and lower range. When users configure a pump for their swimming pool, they generally configure a pump with a larger rated flow rate and leave a certain threshold. When the filtering device in the circulating water pipe is slightly blocked after long-term use, users may not check it in a short time, the water pressure in the circulating water pipe increases, and there may be potential hazards of water pipe bursting and damage to the electrolysis device.

[0007] The flow rate passing through the salt chlorine generator cannot be accurately adjusted. Users adjust the flow rate by adjusting the circulation pump. As Figure 1 shown, in an installation environment with a water distribution pipeline, it is impossible to ensure the flow rate passing through the salt chlorine electrolysis device. Either too large or too small water flow rate will lead to low efficiency of the electrolysis device.

[0008] To maintain good water quality in the pool, various water quality parameters in the water need to meet certain standards. Currently, in the salt chlorine generator system, users may install some water quality-related sensor systems independently to observe various parameters of the water in the pool. Users need to check these complex water quality parameters tediously and adjust the usage of the salt chlorine generator system according to various water quality parameters. In this way, the usage and maintenance are difficult, and the learning cost for users is very high.

[0009] The chlorine disinfection component generated by the salt chlorine generator through electrolysis decomposes relatively fast under strong sunlight intensity or ultraviolet intensity, and decomposes relatively slowly under weak sunlight intensity or ultraviolet intensity. Currently, there is a waste of operation time in some electrolysis devices of the salt chlorine generator, reducing the effective service life of the salt chlorine generator.

[0010] In some salt chlorine systems, the salt chlorine generator is not equipped with a filtering device. In some pool disinfection systems, users do not install a dedicated pool filtering device, which may cause particulate impurities such as sand and gravel in the circulating water flowing through the salt chlorine generator. These impurities will scratch the electrolysis sheet when passing through the electrolysis device, resulting in premature failure of the electrolysis device.

[0011] The replacement cost of individual equipment in the salt chlorine system is high. When replacing accessories, it involves reinstalling the equipment and re-laying cables, which is difficult and costly. Summary of the Invention

[0012] To solve the above problems, the present invention proposes a salt chlorine generation control method, system and salt chlorine generator. Based on water pressure and flow parameters, the present invention judges the pipeline pressure and blockage situation, and issues an alarm in time or even controls the flow rate of the circulating water pump in case of abnormality, ensuring the safety and service life of the water circulation pipeline and the salt chlorine generator. It can judge the water flow rate through the internal electrolysis device and adjust it to the optimal flow rate state to ensure the highest electrolysis efficiency and extend the service life of the electrolysis device; through water quality parameters and meteorological parameters, it flexibly adjusts the operation time of the electrolysis device, improves the effective electrolysis time of the electrolysis device of the salt chlorine generator, reduces the ineffective operation time, and further extends the service life of the electrolysis device.

[0013] According to some embodiments, the present invention adopts the following technical solutions:

[0015] Obtain water quality parameters and meteorological data;

[0016] According to the water quality parameters, judge whether the concentration of the chlorine disinfection component in the water meets the standard. If the concentration meets the standard, do not start the electrolysis device / program. If the concentration does not meet the standard, start the electrolysis device / program, and calculate the power supply time of the electrolysis device according to the concentration difference of the chlorine disinfection component to form a control instruction;

[0017] Determine a weighting value according to meteorological data to fine-tune the control instruction;

[0019] As an alternative implementation, the water quality parameter includes the measured value of the water oxidation-reduction potential.

[0020] As an alternative implementation, the meteorological data includes the sunshine intensity and the ultraviolet index.

[0021] As an alternative implementation, the specific process of judging whether the concentration of the chlorine disinfection component in the water meets the standard according to the water quality parameter includes: obtaining the measured value of the pool water oxidation-reduction potential from the OCR sensor in the system, comparing the measured value with a preset threshold, and if the measured value is less than the threshold, it is determined that the concentration of the chlorine disinfection component in the water does not meet the standard.

[0022] As an alternative implementation, the process of calculating the power supply time of the electrolysis device according to the concentration difference of the chlorine disinfection component includes: in each power supply cycle, the power supply time t of the electrolysis device is N*△ concentration / m, where N is the total duration of the power supply cycle, m is a preset parameter less than N, and △ concentration is the concentration difference of the chlorine disinfection component.

[0023] As an alternative implementation, the specific process of determining the weighting value according to the meteorological data includes: comprehensively processing the sunshine intensity and the ultraviolet index, dividing the obtained weighting value into multiple levels, and weighting the weights within the set range for the power supply time corresponding to the control instruction.

[0024] As a further defined implementation, the set range is [1.0,..., 1.a], a is greater than 0, the number of levels is b, the set range is divided at intervals of (a + 1) / 10b, and the weight of the i-th level is 1.0 + (a + 1)(i - 1) / 10b.

[0025] As an alternative implementation, regularly obtain the concentration of the chlorine disinfection component. When the concentration difference △ concentration is zero, the concentration of the chlorine disinfection component meets the standard, and the electrolysis device is stopped.

[0027] A data acquisition module for acquiring water quality parameters and meteorological data;

[0028] A control module, which is used to determine whether the concentration of the chlorine disinfection component in water meets the standard according to the water quality parameters. If the concentration meets the standard, the electrolysis device / program is not started. If the concentration does not meet the standard, the electrolysis device / program is started, and the power supply time of the electrolysis device is calculated according to the concentration difference of the chlorine disinfection component to form a control instruction;

[0029] A weighting module, which is used to determine a weighting value according to meteorological data to fine-tune the control instruction;

[0030] An execution module, which is used to control the electrolysis device with the fine-tuned control instruction.

[0031] A salt chlorine generator includes the above control system or is controlled by the above control method.

[0040] As a further implementation, the front end and the rear end of the salt chlorine generator are respectively connected to the pipeline through interfaces. At the entrance of the connected pipeline, a filter screen is provided, and an electric control valve is provided to control the opening of the pipeline. The water flows through the electrolysis device and is electrolyzed and then flows out from the water outlet, and the chlorine disinfection component is sent into the pipeline.

[0041] As a further implementation, the salt chlorine generator further includes a controller, which is used to compare the detected liquid pressure with the preset upper and lower pressure limit values. If the liquid pressure is greater than the preset upper pressure limit value, the opening of the electric control valve is reduced. If the pressure is less than the preset lower pressure limit value, the opening of the electric control valve is increased. If the opening of the electric control valve has reached the maximum but the pressure is still less than the preset lower pressure limit value, a warning message is sent to prompt to increase the power of the circulating water pump on the pipeline;

[0042] The controller is connected to the detection component and the interaction module.

[0058] In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0059] Embodiment 1

[0060] As Figure 2 shown, a salt-chlorine generation control method includes the following steps:

[0061] Judge whether the concentration of chlorine disinfection components in the water meets the standard according to the water quality parameters. If the concentration meets the standard, there is no need to start the electrolysis program / device. If the concentration does not meet the standard, according to the concentration difference △ of the chlorine disinfection components concentration Automatically control the power supply time of the electrolysis device;

[0062] According to the obtained weather information, use the sunlight intensity and ultraviolet index as the weighting values of the power supply time of the electrolysis device. The sunlight intensity and ultraviolet index are comprehensively processed, and the obtained weighting values are divided into multiple levels. On the basis of the above-mentioned power supply time of the electrolysis device, weight is multiplied, and the power supply cycle is reset after the power supply cycle is completed.

[0063] In this way, in the case of weak sunlight intensity or ultraviolet intensity, the power supply time of the electrolysis device can be appropriately reduced every day. In the case of strong sunlight intensity or ultraviolet intensity, the power supply time of the electrolysis device can be appropriately increased, which can greatly extend the service life of the salt-chlorine generator.

[0064] During the entire electrolysis process, the concentration of the chlorine disinfection component is regularly obtained. When the concentration difference △ concentration is zero, the concentration of the chlorine disinfection component meets the standard, and the electrolysis program / device is stopped.

[0065] In this embodiment, the power supply cycle of the electrolysis device is set to 6 hours, and the time t for the control board to control the power supply of the electrolysis device in each cycle is 6*△ concentration / m, where m is taken as 4.2.

[0066] In this embodiment, the levels are set to 6, and the weighting values are respectively taken as [1.0, 1.1, 1.2, 1.3, 1.4, 1.5], that is, for level one, the weighting value is 1.0, and for level four, the weighting value is 1.3.

[0067] Embodiment Two

[0068] A salt chlorine generation control system includes:

[0069] A data acquisition module for acquiring water quality parameters and meteorological data;

[0070] A control module for judging whether the concentration of the chlorine disinfection component in the water meets the standard according to the water quality parameters. If the concentration meets the standard, the electrolysis device / program is not started. If the concentration does not meet the standard, the electrolysis device / program is started, and the power supply time of the electrolysis device is calculated according to the concentration difference of the chlorine disinfection component to form a control instruction;

[0071] A weighting module for determining a weighting value according to the meteorological data to fine-tune the control instruction;

[0072] An execution module for controlling the electrolysis device with the fine-tuned control instruction.

[0073] Embodiment Three

[0074] A control board / controller includes a memory, a processor, and computer instructions stored on the memory and running on the processor. When the computer instructions are run by the processor, each step in the method provided in Embodiment One is completed.

[0075] The control board / controller is connected to the data acquisition module. The data acquisition module is used to acquire water quality parameters and meteorological data, including a concentration detection module for the chlorine disinfection component, and a sunshine intensity and ultraviolet index detection module.

[0076] Embodiment Four

[0077] A salt chlorine generator applies the control method of Embodiment One or includes the system of Embodiment Two or the control board / controller of Embodiment Three.

[0078] Embodiment Five

[0079] A salt chlorine generator, comprising an execution part, a control part and an interaction part.

[0080] Among them, as Figure 3 shown, the execution part includes a sealed housing, an electrolysis device, an electric proportional regulating valve and a detection component. In this embodiment, the detection component includes a pressure sensor, a flow sensor, a PH sensor, an ORP sensor (used to test the oxidation-reduction potential and can obtain the health indicators of the pool water quality), a total alkalinity sensor (total alkalinity helps to stabilize the PH value), a calcium ion sensor and a water temperature sensor. The execution part is responsible for sampling various signals, regulating the water flow rate and electrolysis.

[0081] The control part includes a power supply, an audible and visual alarm device and a control board / controller. The control board / controller is responsible for sampling and processing data of various sensors, supplying power to the electrolysis device, and controlling the electric regulating valve.

[0082] The interaction part includes a display screen interface and a wireless interaction module, which can connect to a user terminal (including but not limited to Bluetooth, WiFi, Zigbee) through the display screen or the wireless module to express various parameter information (including but not limited to the concentration of chlorine disinfection components, PH value, total alkalinity, calcium ion concentration, water temperature and real-time water flow rate of the pool water). The control board can connect to a wireless network through the wireless module to obtain weather data (including but not limited to sunlight intensity, ultraviolet intensity), and automatically adjust the operation time of the electrolysis device according to the weather data.

[0083] As Figure 3 shown, in this embodiment, the execution part is a sealed cabin, and the water inlet and outlet are male threads of sealed interfaces, which are connected in series to the circulation pipeline of the user's pool through female heads of the sealed interfaces. A filter screen is designed at the water inlet to filter out fine sand and gravel. The filter screen can protect the subsequent sensor part and electrolysis device and other components from being scratched by sand and gravel.

[0084] Behind the filter screen is an electric regulating valve. The electric regulating valve receives the PWM control signal of the control board and adjusts the opening of the valve according to the duty ratio information of the PWM control signal to ensure that the water flow rate through the salt chlorine generator is controllable.

[0085] Behind the electric regulating valve are various sensors. These sensors are powered by the control board and send the collected voltage or current signals to the control board, which performs unified calculation and processing. Behind the sensors is the electrolysis device of the salt chlorine generator, which is powered by the control board and directly controlled to open and close. When the control board supplies power, electrolysis starts, and when the control board controls power off, electrolysis stops. The control board detects the working current of the electrolysis device and calculates the real-time salt concentration value of the pool water in combination with the water temperature. This value participates in the control of the electrolysis device as an important parameter. The water flows through the electrolysis device and then flows out from the water outlet, sending the chlorine disinfection components into the circulation pipeline of the pool.

[0086] The cabin contains a control panel, power module, sound and light alarm device, display screen and wireless interactive module. 110VAC or 220VAC mains power is converted into 32V DC power by the power module to supply the control panel. The sound and light alarm is powered by the control panel directly through the relay control. When the alarm information including but not limited to excessive water pipe pressure, high pH value, abnormal water temperature, etc. is triggered, the controller controls the sound and light alarm to sound an alarm. The alarm is released by the user through the touch screen or wireless terminal.

[0087] like Figure 4 As shown, the control panel controls the power supply of the electrolysis device, the opening of the electric regulating valve, and the information alarm of the sound and light alarm according to the operating parameters set by the display screen or the wireless terminal and the control start signal, the pressure sensor, the PH sensor, the ORP sensor, the total alkalinity sensor, the calcium ion sensor, the water temperature sensor, and the signal input of the flow sensor to ensure the normal operation of the salt chlorine generator.

[0088] After the salt chlorine generator is powered on, the control board will reset and perform a self-test procedure, first confirming that the signal input of the pressure sensor, PH sensor, ORP sensor, total alkalinity sensor, calcium ion sensor, water temperature sensor, and flow sensor is normal to ensure the correct reading of water quality information.

[0089] After the self-check procedure is completed, the wireless network connection is executed. After the connection is completed, the local weather data (including but not limited to sunshine intensity, UV index, sunny or rainy information, etc.) is automatically obtained to prepare for the control of the subsequent electrolysis program.

[0090] After the interactive module receives the parameter information set by the user, the control panel starts working according to the parameter information. First, it reads the pressure sensor value. If the pressure is too high, the opening of the electric regulating valve is reduced to reduce the water flow to ensure the safety of the circulation pipeline. If the pressure is too low, the opening of the electric regulating valve is increased to increase the water flow. If the opening of the electric regulating valve has reached the maximum but the pressure is still insufficient, the user is notified through the sound and light alarm or the interactive module to increase the power of the circulating water pump.

[0091] After the water pressure adjustment is completed, the water quality signal sampling and processing program begins. First, the voltage or current signals (analog or digital) of the pressure sensor, PH sensor, ORP sensor, total alkalinity sensor, calcium ion sensor, water temperature sensor, and flow sensor are read in turn. The voltage and current signals are calculated and converted into actual physical quantity parameters and expressed to the user through the interactive part. Abnormal data can be specially marked for users to refer to for real-time water quality information.

[0092] In this embodiment, the control board obtains the measured value of the oxidation-reduction potential of the pool water (unit: mV) according to the OCR sensor in the system. A threshold value of this value can be set in the program. By comparing the difference between the threshold value and the measured value, it is judged whether the concentration of the chlorine disinfection component in the water meets the standard. If the concentration meets the standard, the electrolysis program does not need to be started. If the concentration does not meet the standard, the control board calculates according to the concentration difference △ concentration to automatically control the power supply time of the electrolysis device. The power supply cycle of the electrolysis device is 6 hours each time. The time t for the control board to control the power supply of the electrolysis device in each cycle is 6*△ concentration / 4.2.

[0093] The control board processes the weather information obtained by the wireless module, uses the sunshine intensity and the ultraviolet index as the weighting values for the power supply time of the electrolysis device. The control board comprehensively processes the sunshine intensity and the ultraviolet index, divides the obtained sunshine intensity into n levels, and assigns values from 1.0 to 1.n respectively. The ultraviolet level is divided into m levels, and values from 1.0 to 1.m are assigned respectively. The final weighting value calculation method is 1.a*1.b, where 0≤a≤n and 0≤b≤m.

[0094] The obtained weighting values can be divided into 4 or more levels. Multiply the power supply time of the electrolysis device described above by the final weighting value greater than or equal to 1 or the weighted value after dividing the levels. After the power supply cycle is completed, reset the power supply cycle, that is, start a new 6-hour power supply cycle.

[0095] During the entire electrolysis process, the control board regularly reads the concentration of the chlorine disinfection component. When the concentration difference △ concentration is zero, the concentration of the chlorine disinfection component meets the standard, and the control board stops the electrolysis program.

Moreover, the present invention can take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD - ROM , optical memory, etc.) containing computer-usable program code.

9. A salt chlorine generator according to claim 8, characterized in that, The front end and the rear end of the salt-chlorine generator are respectively connected to the pipeline through interfaces. At the entrance of the pipeline connected, a filter screen is provided, and an electric control valve is provided to control the opening of the pipeline. The water flows through the electrolysis device and flows out from the water outlet, sending the chlorine disinfection component into the pipeline.

10. A salt chlorine generator according to claim 9, characterized in that, The salt-chlorine generator further includes a controller. The controller is used to compare the detected liquid pressure with the preset upper and lower pressure limit values. If the liquid pressure is greater than the preset upper pressure limit value, the opening of the electric control valve is reduced. If the pressure is less than the preset lower pressure limit value, the opening of the electric control valve is increased. If the opening of the electric control valve has reached the maximum but the pressure is still less than the preset lower pressure limit value, a warning message is sent to prompt to increase the power of the circulating water pump on the pipeline; The controller is connected to the detection component and the interaction module.
