Description

Technical Field

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

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] A salt chlorine generator is a device that uses the principle of electrolysis to disinfect water. It mainly produces sodium hypochlorite by electrolyzing salt water, which is used to kill bacteria, algae and pollutants in water. It 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. In order for a salt chlorine generator to work properly, it usually requires a water circulation pipeline and a circulating water pump. After the circulating water pump is working, the water in the swimming pool flows from the pipeline through the electrolysis device, thereby electrolyzing and producing chlorine disinfection components. During use, the user dissolves the salt directly in the pool water, and the electrolysis device is connected in series to the circulating water pipeline. When the circulating water pump is working, the water is sent to the water inlet of the electrolysis device, and then flows out through the outlet after being treated 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 produce 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: the rated salt concentration needs to be maintained, the appropriate voltage needs to be provided, and the electrolyte sheets in the electrolysis device also need to work at a suitable temperature, otherwise the service life of the electrolyte sheets will be reduced.

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

[0006] There are potential safety hazards. When the salt chlorine generator is working, a certain water flow rate needs to be maintained in the electrolysis device. This parameter has a limited upper and lower range. When users configure water pumps for their swimming pools, they generally configure water pumps with larger rated flow rates, leaving a certain threshold. When the filter device in the circulating water pipe is slightly clogged after long-term use, the user may not check it in a short period of time, and the water pressure in the circulating water pipe increases, which may cause the risk of water pipe bursting and damage to the electrolysis device.

[0007] It is not possible to accurately adjust the flow through the salt chlorine generator. The user adjusts the flow by adjusting the circulating water pump, such as Figure 1 As shown, in an installation environment with a water distribution pipeline, the flow rate through the salt chlorine electrolysis device cannot be guaranteed. Too much or too little water flow will lead to low efficiency of the electrolysis device.

[0008] To maintain good water quality in the swimming pool, various water quality parameters in the water must meet certain standards. At present, users may install some water quality-related sensor systems in the salt chlorine generator system to observe various parameters of the water in the swimming pool. Users need to check these complex water quality parameters and adjust the use of the salt chlorine generator system according to various water quality parameters. This makes it difficult to use and maintain, and the user's learning cost is very high.

[0009] To maintain good water quality in the swimming pool, various water quality parameters in the water must meet certain standards. At present, users may install some water quality-related sensor systems in the salt chlorine generator system to observe various parameters of the water in the swimming pool. Users need to check these complex water quality parameters and adjust the use of the salt chlorine generator system according to various water quality parameters. This makes it difficult to use and maintain, and the user's learning cost is very high.

[0010] The chlorine disinfection component produced by electrolysis in the salt chlorine generator decomposes faster when the sunlight intensity or ultraviolet intensity is strong, and decomposes slower when the sunlight intensity or ultraviolet intensity is weak. At present, the operation time of some electrolysis devices of the salt chlorine generator is wasted, which reduces the effective service life of the salt chlorine generator.

[0011] The salt chlorine generator in some salt chlorine systems does not have a filtering device. In some swimming pool disinfection systems, users do not install dedicated swimming pool filtering devices. This may cause the circulating water flowing through the salt chlorine generator to contain granular impurities such as sand and gravel. These impurities may scratch the electrolytic sheet when passing through the electrolytic device, causing the electrolytic device to fail prematurely.

[0012] The cost of replacing damaged equipment in the salt-chlorine system is high. Replacing accessories requires reinstalling the equipment and rewiring the cables, which is difficult and costly. Summary of the invention

[0013] In order to solve the above problems, the present invention proposes a salt chlorine generation control method, system and salt chlorine generator. The present invention judges the pipeline pressure and blockage based on water pressure and flow parameters, issues an alarm in time when there is an abnormality, and even controls the flow of the circulating water pump, thereby ensuring the safety and life of the water circulation pipeline and the salt chlorine generator. The water flow rate flowing through the internal electrolysis device can be judged and adjusted to the optimal flow state to ensure the highest electrolysis efficiency and extend the service life of the electrolysis device; the operating time of the electrolysis device can be flexibly adjusted through water quality parameters and meteorological parameters, thereby increasing the effective electrolysis time of the salt chlorine generator electrolysis device, reducing the ineffective operating time, and further extending the service life of the electrolysis device.

[0059] In the absence of conflict, the embodiments in this application and the features in the embodiments may be combined with each other.

[0060] Embodiment 1

[0061] like Figure 2 As shown, a method for controlling salt chlorine generation comprises the following steps:

[0062] According to the water quality parameters, it is judged whether the concentration of chlorine disinfection components in the water meets the standard. 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;

[0063] According to the weather information obtained, the sunshine intensity and the ultraviolet index are used as weighted values ​​of the power supply time of the electrolysis device. The sunshine intensity and the ultraviolet index are comprehensively processed, and the weighted values ​​obtained are divided into multiple levels. The power supply time of the above-mentioned electrolysis device is technically weighted and multiplied by the weight. The power supply cycle is reset after the power supply cycle is completed.

[0064] In this way, under weather conditions with weak sunlight or ultraviolet intensity, the power supply time of the electrolysis device can be appropriately reduced every day. Under weather conditions with strong sunlight 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.

[0065] During the entire electrolysis process, the concentration of the chlorine disinfection component is obtained regularly. When the concentration difference of the chlorine disinfection component is △ concentration When it reaches zero, the concentration of chlorine disinfection components reaches the standard and the electrolysis program / device is stopped.

[0066] In this embodiment, each power supply cycle of the electrolysis device is set to 6 hours, and the control board controls the power supply of the electrolysis device for a period of t of 6*△ concentration / m, m is taken as 4.2.

[0067] In this embodiment, the levels are set to 6, and the weighted values ​​are respectively taken as [1.0, 1.1, 1.2, 1.3, 1.4, 1.5], that is, the weighted value of level 1 is 1.0, and the weighted value of level 4 is 1.3.

[0068] Embodiment 2

[0069] A salt chlorine generation control system, comprising:

[0070] Data acquisition module, used to obtain water quality parameters and meteorological data;

[0071] A control module is used to determine 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;

[0072] A weighting module, used to determine a weighting value according to meteorological data to fine-tune the control instruction;

[0073] The execution module is used to control the electrolysis device with the fine-tuned control instructions.

[0074] Embodiment 3

[0075] A control board / device comprises a memory and a processor and computer instructions stored in the memory and running on the processor. When the computer instructions are run by the processor, each step of the method provided in embodiment 1 is completed.

[0076] The control panel / device is connected to a data acquisition module, which is used to acquire water quality parameters and meteorological data, including a concentration detection module for chlorine disinfection components, and a sunlight intensity and ultraviolet index detection module.

[0077] Embodiment 4

[0078] A salt chlorine generator, using the control method of embodiment 1 or including the system of embodiment 2 or the control panel / device of embodiment 3.

[0079] Embodiment 5

[0080] A salt chlorine generator comprises an execution part, a control part and an interaction part.

[0081] Among them, Figure 3 As shown, the execution part includes a sealed housing, an electrolysis device, an electric proportional control valve and a detection component. In this embodiment, the detection component includes a pressure sensor, a flow sensor, a pH sensor, an OPR sensor (used to test the oxidation-reduction potential, which can be used to determine the sanitation index of the swimming pool water quality), a total alkalinity sensor (total alkalinity helps stabilize the pH value), a calcium ion sensor and a water temperature sensor. The execution part is responsible for sampling various signals, regulating water flow and electrolysis.

[0082] The control part includes power supply, sound and light alarm device and control board / device. The control board / device is responsible for sampling and processing of various sensor data, power supply of electrolysis device and control of electric regulating valve.

[0083] The interactive part includes a display screen interface and a wireless interactive module, which can connect to a user terminal (including but not limited to Bluetooth, WiFi, Zigbee) through a display screen or a wireless module to express various parameter information (including but not limited to the chlorine disinfection component concentration, pH value, total alkalinity, calcium ion concentration, water temperature and real-time water flow of the swimming pool water). The control panel can connect to the wireless network through the wireless module to obtain weather data (including but not limited to sunshine intensity, ultraviolet intensity), and automatically adjust the operating time of the electrolysis device according to the weather data.

[0084] like Figure 3 As shown, in this embodiment, the execution part is a sealed cabin, and the water inlet and the water outlet are male threads of the sealing interface, which are connected in series to the circulation pipe of the user's swimming pool through the female head of the sealing interface. A filter is designed at the water inlet to filter fine sand and gravel. The filter can protect the sensor part and electrolysis device behind from being scratched by sand and gravel.

[0085] Behind the filter is an electric regulating valve, which receives the PWM control signal from the control board and adjusts the valve opening according to the duty cycle information of the PWM control signal to ensure that the water flow through the salt chlorine generator is controllable.

[0086] Behind the electric regulating valve are various sensors, which are powered by the control panel and transmit the collected voltage or current signals to the control panel, which performs unified calculations and processing. Behind the sensor is the electrolysis device of the salt chlorine generator, which is powered by the control panel and directly controls the opening and closing. When the control panel is powered, electrolysis starts, and when the control panel is powered off, electrolysis stops. The control panel detects the working current of the electrolysis device and calculates the real-time salt concentration value of the swimming pool water in combination with the water temperature. This value is used as an important parameter to participate in the control of the electrolysis device. After the water flows through the electrolysis device, it flows out from the outlet, and the chlorine disinfection components are sent to the circulation pipeline of the swimming pool.

[0087] 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.

[0088] 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 OPR 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.

[0089] 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, OPR sensor, total alkalinity sensor, calcium ion sensor, water temperature sensor, and flow sensor is normal to ensure the correct reading of water quality information.

[0090] 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, ultraviolet index, sunny or rainy information, etc.) is automatically obtained to prepare for the control of the subsequent electrolysis program.

[0091] 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.

[0092] 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, OPR 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.

[0093] In this embodiment, the control board obtains the measured value of the redox potential of the swimming pool water (unit: mV) according to the OCR sensor in the system. A threshold value of the value can be set in the program. By comparing the difference between the threshold value and the measured value, it is determined whether the concentration of the chlorine disinfection component in the water meets the standard. If the concentration meets the standard, there is no need to start the electrolysis program. If the concentration does not meet the standard, the control board will determine the concentration difference of the chlorine disinfection component according to the concentration difference △ concentration Automatically control the power supply time of the electrolysis device. Each power supply cycle of the electrolysis device is 6 hours. The control board controls the power supply time t of the electrolysis device per cycle as 6*△ concentration / 4.2.

[0094] The control board processes the weather information obtained by the wireless module, and uses the sunshine intensity and the ultraviolet index as the weighted values ​​of 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 ​​of 1.0-1.n respectively, and divides the ultraviolet level into m levels, and assigns values ​​of 1.0-1.m respectively. The final weighted value calculation method is 1.a*1.b, 0≤a≤n, 0≤b≤m.

[0095] The weighted value that can be obtained is divided into 4 or more levels. The final weighted value greater than or equal to 1 or the weighted value after the division is multiplied by the power supply time of the above-mentioned electrolysis device. After the power supply cycle is completed, the power supply cycle is reset, that is, the 6-hour power supply cycle is restarted.

[0096] During the entire electrolysis process, the control panel regularly reads the concentration of the chlorine disinfection component. concentration When it reaches zero, the concentration of chlorine disinfection components reaches the standard and the control board stops the electrolysis process.

Moreover, the present invention may 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 storage, etc.) containing computer-usable program code.

A salt chlorine generator as claimed in claim 11, characterized in that: The front end and the rear end of the salt chlorine generator are respectively connected to the pipeline through interfaces. A filter screen and an electric regulating valve are provided at the inlet of the pipeline to control the opening of the pipeline. After the water is electrolyzed by the electrolysis device, it flows out from the water outlet to deliver the chlorine disinfection component into the pipeline.

13. A salt chlorine generator as claimed in claim 12, characterized in that: The salt chlorine generator also includes a controller, which is used to compare the detected liquid pressure with the preset upper and lower pressure limits. If the liquid pressure is greater than the preset upper pressure limit, the opening of the electric regulating valve is reduced; if the pressure is less than the preset lower pressure limit, the opening of the electric regulating valve is increased; if the opening of the electric regulating valve has reached the maximum but the pressure is still less than the preset lower pressure limit, an early warning message is issued to prompt the power of the circulating water pump on the pipeline to be increased; The controller is connected to the detection component and the interaction module.
