[0043] Increase and decrease control parameter: Determined according to the positive or negative of the flow rate difference, used to indicate whether the valve should increase the opening (to increase the flow rate) or decrease the opening (to decrease the flow rate).

[0046] Adjustment change period: The time interval for periodically obtaining the current flow rate value, used to achieve regular monitoring and adjustment of the ammonia water flow rate.

[0047] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to Figure 1 , an embodiment of the method for adjusting the ammonia water flow rate in the embodiments of the present invention includes:

[0048] 101. Obtain the current flow rate value of ammonia water, and calculate the difference between the current flow rate value and a preset expected flow rate value to obtain a flow rate difference;

[0049] Specifically, the precise regulation of ammonia water flow rate is crucial for multiple fields such as chemical industry, refrigeration, and agriculture. For this reason, the ammonia water flow rate regulating device integrates a high-precision built-in flow sensor, which can sense the flow state of ammonia water in the pipeline in real time. The ammonia water flow rate regulating device also supports connecting to an external flow measurement device to adapt to scenarios with different scales and precision requirements. Whether it is real-time continuous monitoring or periodic detection according to a preset regulation change period (such as every minute, every hour, or automatically adjusted according to process fluctuations), the ammonia water flow rate regulating device can accurately capture the current flow rate value in the ammonia water pipeline. The current flow rate value is expressed in the form of volumetric flow rate (such as cubic meters per hour) or mass flow rate (such as kilograms per hour), depending on the process requirements, which are not limited here.

[0050] Furthermore, in order to achieve precise flow control, the ammonia water flow rate regulating device has a built-in intelligent algorithm that can automatically retrieve the preset expected flow rate value from the memory. The expected flow rate value can be optimized based on process requirements, operation targets, or historical data. Then, the ammonia water flow rate regulating device uses a high-performance processor to perform a subtraction operation, accurately comparing the currently obtained current flow rate value with the preset expected flow rate value, thereby calculating the flow rate difference. The flow rate difference reflects the deviation between the current flow rate and the desired flow rate, and is an important basis for subsequent adjustment actions.

[0051] Optionally, obtain the current flow rate value of real-time ammonia water according to a preset regulation change period. Among them, the ammonia water flow rate regulating device checks whether the preset regulation change period has been reached. If it has, it performs the flow rate value obtaining operation, including steps such as sending a reading instruction to the flow sensor, receiving and processing the flow data returned by the sensor, etc. After obtaining the current flow rate value, it is stored in the internal memory for subsequent calculations. At the same time, the device resets or updates the timer so that the flow rate value obtaining operation can be performed again when the next regulation change period arrives. By periodically obtaining the flow rate value, the query frequency of the device for the flow sensor can be reduced, thereby reducing the overall resource consumption and energy consumption.

[0052] Optionally, obtain the current flow rate value of ammonia water in real time. Among them, the ammonia water flow rate regulating device maintains continuous communication with the flow sensor and listens to the flow data sent by the sensor in real time. When a new flow rate value is received, it compares and calculates based on the latest flow rate value and the preset expected flow rate value to determine whether it is necessary to adjust the opening of the valve. Obtaining the flow rate value in real time can ensure that the device senses the change in flow rate in the first time and makes a quick adjustment accordingly, thereby improving the accuracy and response speed of flow control.

[0053] 102. Calculate the opening control parameter of the valve according to the flow difference and the preset opening change rate, and determine the increase or decrease control parameter of the valve according to the positive or negative of the flow difference;

[0054] Specifically, in order to convert the flow difference into a specific valve adjustment action, the ammonia water flow adjustment device reads the preset opening change rate from the memory. The opening change rate is comprehensively determined according to factors such as valve characteristics, pipeline resistance, and fluid properties, and represents the rate or ratio of the valve opening changing with the flow difference. The ammonia water flow adjustment device uses a preset algorithm to calculate the valve opening adjustment amount according to the flow difference and the opening change rate, and then encapsulates it as the opening control parameter.

[0055] Specifically, after calculating the valve opening adjustment amount, further determine the positive or negative of the flow difference. If the flow difference is positive, it means that the current flow is higher than expected, and at this time, the opening of the valve needs to be reduced to decrease the flow; conversely, if the flow difference is negative, it means that the current flow is lower than expected, and the opening of the valve needs to be increased to increase the flow. According to the judgment result, automatically set the corresponding increase or decrease control parameter (such as an increase flag or a decrease flag).

[0056] 103. Control the ammonia water valve according to the opening control parameter and the increase or decrease control parameter;

[0057] Specifically, the ammonia water flow adjustment device sends a control signal to the ammonia water valve through a variety of control interfaces (including analog signal output, digital signal output, or pulse signal output, etc.). After receiving the control signal, the valve will adjust its opening, thereby changing the flow of ammonia water. In the closed-loop control process, the ammonia water flow adjustment device can ensure that the flow of ammonia water always remains within the preset expected range, meeting the process requirements and operation objectives.

[0058] In the embodiment of the present invention, obtain the current flow value of ammonia water, and calculate the difference between the current flow value and the preset expected flow value to obtain the flow difference; calculate the opening control parameter of the valve according to the flow difference and the preset opening change rate, and determine the increase or decrease control parameter of the valve according to the positive or negative of the flow difference; control the ammonia water valve according to the opening control parameter and the increase or decrease control parameter. By directly obtaining the current flow of ammonia water and comparing it with the expected flow value, flexibly calculating the opening control parameter of the valve in combination with the preset opening change rate, and determining the increase or decrease control parameter of the valve according to the positive or negative of the flow difference, the rapid and accurate adjustment of the ammonia water flow is realized. Greatly simplifies the complexity of parameter calculation, effectively avoids the problem of lag in ammonia water control response, and ensures the real-time nature of ammonia water flow control.

[0059] Traditional methods for regulating the flow rate of ammonia water often have problems such as low regulation accuracy and slow response speed. This is mainly due to the lack of precise flow monitoring and regulation mechanisms. With the development of industrial automation and intelligence, higher requirements are put forward for the precise control of the ammonia water flow rate. Therefore, a more efficient and precise method for regulating the ammonia water flow rate is needed to solve these problems. To solve the above technical problems, an optional embodiment is proposed in the present invention.

[0060] Optionally, referring to Figure 2 , Figure 2 FIG. is a schematic diagram of a specific embodiment of step 102 of the control method for the wireless charging device in the embodiment of the present invention. Step 102 further includes the following specific implementation manners:

[0061] 1021. Calculate the ratio of the flow difference to a preset allowable error value;

[0062] Specifically, calculate the ratio of the flow difference to the allowable error value:

[0063] First, calculate the ratio of the flow difference to the preset allowable error value. The ratio is used to evaluate the deviation degree between the current flow rate and the expected flow rate.

[0064] 1022. If the absolute value of the ratio is greater than or equal to 1, calculate the opening control parameter of the valve according to the ratio and the preset opening change rate.

[0065] Specifically, if the absolute value of the ratio is greater than or equal to 1, it means that the deviation degree between the current flow rate and the expected flow rate has exceeded the allowable range and needs to be adjusted. In this case, calculate the opening control parameter of the valve according to the ratio and the preset opening change rate.

[0066] If the absolute value of the ratio is greater than or equal to 1, then perform a square root operation on the ratio to obtain a magnification value. The magnification value reflects the severity of the flow deviation and is used to adjust the opening change amount of the valve.

[0067] At the same time, obtain the current opening value of the valve, and calculate a new opening control parameter in combination with the magnification value and the preset opening change rate. The opening control parameter will be used to control the opening of the valve to adjust the flow rate of the ammonia water.

[0068] In this optional embodiment, by introducing the allowable error value and the ratio judgment mechanism, it is possible to more accurately judge when flow regulation is needed, avoid unnecessary regulation operations, and improve the stability and reliability of the ammonia water flow regulation. Adjust the opening change amount of the valve according to the severity of the flow deviation (i.e., the absolute value of the ratio), realizing the refined control of the ammonia water flow rate. The adjustment method is more flexible and efficient, and can reach the expected flow rate value faster.

[0069] Precisely controlling the flow rate is a key factor in ensuring the stability and efficiency of the process. However, due to the influence of various factors (such as pipeline pressure fluctuations, valve response delays, etc.), there is often a certain deviation between the actual flow rate and the target flow rate. To handle these deviations, in conventional ammonia water flow rate adjustment methods, frequent adjustments are made, resulting in excessive wear of the valves and motors. To solve the above technical problems, an alternative embodiment of the present invention is proposed.

[0070] Optionally, after step 1021, the following specific implementation manners are further included:

[0071] 1023. If the absolute value of the ratio is less than 1, return to execute the step of obtaining the current flow rate value of the ammonia water.

[0072] In this alternative embodiment, when the absolute value of the ratio of the flow rate difference to the allowable error value is less than 1, it means that the difference between the current flow rate value and the target flow rate value is very small and within the allowable error range. At this time, instead of directly adjusting the valve opening, the current flow rate value is continuously monitored, which can avoid frequent adjustments caused by small errors.

[0073] Traditional ammonia water flow rate adjustment methods often have problems such as insufficient adjustment accuracy and slow response speed. This is mainly due to the lack of precise flow rate monitoring and adjustment mechanisms. With the development of industrial automation and intelligence, higher requirements are put forward for the accuracy and stability of flow rate control. Therefore, a more precise and efficient ammonia water flow rate adjustment method is needed to meet these requirements. To solve the above technical problems, an alternative embodiment of the present invention is proposed.

[0074] Optionally, referring to Figure 2 , Figure 2 is a schematic diagram of a specific embodiment of step 1022 of the control method of the wireless charging device in the embodiment of the present invention. Step 1022 further includes the following specific implementation manners:

[0075] 10221. If the absolute value of the ratio is greater than or equal to 1, take the square root of the ratio to obtain a magnification factor, and obtain the current opening value of the valve;

[0076] Specifically, when the absolute value of the ratio of the flow rate difference to the preset allowable error value is greater than or equal to 1, first perform a square root operation on this ratio to obtain a magnification factor. The magnification factor represents the severity of the flow rate deviation and is used to calculate the adjustment amount of the valve opening in the subsequent calculation.

[0077] Then, obtain the current opening value of the current valve. The current opening value reflects the current opening degree of the valve and is the basis for calculating the new opening control parameter.

[0078] 10222. Calculate the opening control parameter according to the current opening value, the magnification factor, and the opening change rate.

[0079] Specifically, based on the current valve opening value, the magnification value calculated previously, and the preset opening change rate, a new opening control parameter can be calculated. Specifically, the magnification value can be multiplied by the opening change rate to obtain an opening change value, and then this change value can be added to the current opening value to obtain the new opening control parameter.

[0080] In this alternative embodiment, through technical means such as introducing square root of ratio and precisely calculating the opening control parameter, precise control and adjustment of the ammonia water flow are achieved, thereby improving the adjustment accuracy of the ammonia water flow.

[0081] Traditional methods for regulating ammonia water flow often have problems such as insufficient adjustment accuracy and slow response speed. This is mainly due to the lack of precise flow monitoring and adjustment mechanisms. With the development of industrial automation and intelligence, higher requirements are put forward for the accuracy and stability of flow control. Therefore, a more precise and efficient method for regulating ammonia water flow is needed to meet these requirements. To solve the above technical problems, an alternative embodiment of the present invention is proposed.

[0082] Optionally, step 1022 further includes the following specific implementation manners:

[0083] 10221. If the absolute value of the ratio is greater than or equal to 1, take the square root of the ratio to obtain a magnification value, and obtain the current opening value of the valve.

[0084] Specifically, when the absolute value of the ratio of the flow difference to the preset allowable error value is greater than or equal to 1, first perform a square root operation on this ratio to obtain a magnification value. The magnification value represents the severity of the flow deviation and is used to calculate the adjustment amount of the valve opening subsequently.

[0085] Then, obtain the current opening value of the current valve. The current opening value reflects the current opening degree of the valve and is the basis for calculating the new opening control parameter.

[0086] 10222. Calculate the opening control parameter according to the current opening value, the magnification value, and the opening change rate.

[0087] Specifically, based on the current opening value of the valve, the magnification value calculated previously, and the preset opening change rate, a new opening control parameter can be calculated.

[0088] Optionally, calculate the product of the magnification value and the opening change rate to obtain an opening change value; add the current opening value and the opening change value to obtain the opening control parameter. Specifically, the magnification value can be multiplied by the opening change rate to obtain an opening change value, and then this change value can be added to the current opening value to obtain the new opening control parameter.

[0089] In a specific example, it is defined that:

[0090] ΔQ: Flow difference (the difference between the current flow value and the expected flow value);

[0091] ε: Preset allowable error value;

[0092] ɑ: Ratio of the flow difference to the allowable error value

[0093] β: If |ɑ| ≥ 1, then (Multiplier value);

[0094] K: Preset opening change rate;

[0095] O current : Current opening value of the valve;

[0096] O control : Opening control parameter of the valve;

[0097] When |α| ≥ 1, the steps for calculating the opening control parameter are as follows:

[0098] Calculate the multiplier value

[0099] Calculate the opening change value ΔQ = β × K;

[0100] Calculate the opening control parameter O control = O current + ΔQ.

[0101] In summary, a formula can be obtained to represent the calculation of the opening control parameter:

[0102]

[0103] In this alternative embodiment, through technical means such as introducing ratio square root and precisely calculating the opening control parameter, precise control and adjustment of the ammonia water flow are achieved, thereby improving the adjustment accuracy of the ammonia water flow.
