[0022] The dynamic pressure adjustment method provided in this application is used in the scenario of kitchen exhaust fumes. Based on the above application scenario, it can be understood that the executing entity of each step can be a computer device. This computer device refers to any electronic device with data computing, processing and storage capabilities, such as mobile phones, PCs (Personal Computers), tablet computers and other terminal devices, or it can be a server or other devices. This application does not limit this.

[0023] Figure 1This is a flowchart of a method for dynamically adjusting air pressure provided in an embodiment of this application, such as... Figure 1 As shown, it includes: Step S101: Periodically acquire environmental parameters and historical air pressure parameters, and calculate the current air pressure deviation value based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in the preset target air pressure range.

[0024] Among them, environmental parameters refer to various detectable and quantifiable physical, chemical, and biological quantities that characterize the environmental state within a specific space or scenario, including temperature data, humidity data, and control quality data. Historical air pressure parameters refer to a set of atmospheric pressure-related data that has been continuously or periodically collected, stored, and preprocessed by an air pressure detection device within a specific space over a set historical time period, including the maximum and minimum air pressure values, fluctuation amplitude, and rate of change during the historical period. Actual air pressure values ​​refer to the instantaneous atmospheric pressure values ​​collected in real time by an air pressure detection device within the monitoring space. Preset target air pressure ranges refer to a set of pre-set air pressure thresholds that cover a reasonable range of atmospheric pressure values ​​within the target monitoring space, based on the requirements of the target application scenario. The midpoint air pressure value within the preset target air pressure range is a reference air pressure value calculated by arithmetic averaging the lower and upper limits of the preset target air pressure range, and serves as the central reference point of the preset target air pressure range. The current air pressure deviation value refers to the difference between the actual air pressure value in the target monitoring space and the preset reference air pressure value. It is the core parameter for determining the degree to which the current air pressure state deviates from the ideal state and can be expressed as e(k).

[0025] In one embodiment, the corresponding environmental parameters collected in real time by various types of sensors, as well as the air pressure parameters calculated in history, are periodically acquired. The midpoint air pressure value is calculated based on the boundary value of the pre-set target air pressure range. The difference between the actual air pressure value contained in the environmental parameters and the midpoint air pressure value is calculated to obtain the current air pressure deviation value.

[0026] Step S102: Compare the current air pressure deviation value with the preset deviation threshold, determine the adjustment direction based on the comparison result, and determine the target coefficient range based on the current air pressure deviation value, historical air pressure parameters, adjustment direction and preset adjustment rules.

[0027] The preset deviation threshold can refer to the critical value used to determine the operating status of the kitchen fan. The adjustment direction can refer to the operating direction used to indicate whether the kitchen fan is charging or deflating. The preset adjustment rule can refer to the adjustment strategy that is pre-defined to increase or decrease each coefficient range based on the air pressure control requirements of the target application scenario. The target coefficient range can refer to the reasonable value range of each calculation parameter involved in the preset algorithm.

[0028] In one embodiment, the absolute value of the current air pressure deviation is determined, and this absolute value is compared with a preset first deviation threshold and a preset second deviation threshold. Based on the comparison results and the adjustment direction, a proportional coefficient range, an integral coefficient range, and a derivative coefficient range are determined. The preset first deviation threshold is less than the preset second deviation threshold. The absolute value of the current air pressure deviation can refer to the non-negative quantified value obtained by performing an absolute value operation on the current air pressure deviation. The preset first deviation threshold can refer to a first-level critical value pre-set to classify the severity of air pressure deviations for the purpose of graded decision-making in air pressure regulation. The preset second deviation threshold can refer to a second-level critical value pre-set to classify the severity of air pressure deviations for the purpose of graded decision-making in air pressure regulation. The preset first deviation threshold is less than the preset second deviation threshold, and the preset first and preset second deviation thresholds together constitute a deviation level classification standard, thereby determining the corresponding target coefficient range based on different deviation levels.

[0029] For example, the absolute value of the current air pressure deviation is calculated to obtain the absolute value of the deviation. This absolute value is then compared with a preset first deviation threshold and a preset second deviation threshold. For example, if the preset first deviation threshold is 0 kPa and the preset second deviation threshold is 1 kPa, the absolute value of the deviation is first compared with the preset first deviation threshold. Based on the comparison result, the fan operating state is determined, such as air supply or exhaust. Then, the absolute value of the deviation is compared with the preset second deviation threshold to determine the large or small deviation stage of the fan operating state. Finally, based on the deviation stage of the current fan operating state, such as the large deviation stage in air supply mode, the adjustment direction is determined.

[0030] Step S103: Output a control signal based on the current air pressure deviation value, the target coefficient range and the preset algorithm, and adjust the actual air pressure value based on the control signal.

[0031] The control signal refers to the quantized electrical signal used to drive the fan, calculated using a preset algorithm based on the current air pressure deviation value of the target monitoring space. The preset algorithm can be a numerical calculation model pre-set to achieve dynamic adjustment of the air pressure in the target space, and can be a PID (proportional-integral-derivative) control algorithm.

[0032] In one embodiment, the target values ​​of each calculation parameter in the preset algorithm are determined based on the target coefficient range determined by the current actual environmental parameters. These target values ​​can be the midpoint of the target coefficient range corresponding to each type of parameter. After determining the target values ​​of each calculation parameter, the corresponding calculation parameters in the preset algorithm are replaced based on these target values ​​to obtain the target algorithm. The current air pressure deviation value is input into the target algorithm, a control signal is output, and this control signal is sent to the corresponding fan to control the fan to perform exhaust or ventilation, thereby achieving dynamic adjustment of the actual air pressure value in the kitchen and maintaining the air pressure value in the kitchen within a reasonable air pressure range.

[0033] This embodiment of the application periodically acquires environmental parameters and historical air pressure parameters. Based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in a preset target air pressure range, it calculates the current air pressure deviation value. This current air pressure deviation value is compared with a preset deviation threshold. Based on the comparison result, an adjustment direction is determined. A target coefficient range is determined based on the current air pressure deviation value, historical air pressure parameters, adjustment direction, and preset adjustment rules. A control signal is output based on the current air pressure deviation value, the target coefficient range, and a preset algorithm. The actual air pressure value is then adjusted based on the control signal. This enables dynamic adjustment of the ventilation system's operating state based on the control command corresponding to the actual air pressure value in the current environment, keeping the air pressure value within a reasonable range, avoiding energy waste in the ventilation system, and improving user comfort.

[0034] Optionally, the target coefficient range is determined based on the current pressure deviation value, historical pressure parameters, adjustment direction, and preset adjustment rules, including: determining the proportional coefficient range, integral coefficient range, and derivative coefficient range corresponding to the adjustment direction; and correcting the integral coefficient range and derivative coefficient range based on the current pressure deviation value, historical pressure parameters, and preset adjustment rules to obtain the target integral coefficient range and target derivative coefficient range.

[0035] The proportional coefficient range, denoted as Kp, refers to a pre-defined range of proportional coefficient values ​​adapted to the pressure deviation level and adjustment direction. The integral coefficient range, denoted as Ki, refers to a pre-defined range of integral coefficient values ​​adapted to the pressure deviation level to eliminate static pressure regulation errors. The derivative coefficient range, denoted as Kd, refers to a pre-defined range of derivative coefficient values ​​adapted to the rate of change of pressure deviation to predict pressure change trends and suppress regulation overshoot. The target integral coefficient range, denoted as Kd, refers to the range of integral coefficient (Ki) values ​​used to calculate the integral term in the PID control algorithm, determined by dynamically correcting the integral coefficients to address the static pressure regulation error elimination requirement. The target derivative coefficient range, denoted as Kd, refers to the range of derivative coefficient (Kd) values ​​used to calculate the derivative term in the PID control algorithm, determined by dynamically correcting the derivative range to predict pressure deviation trends and suppress regulation overshoot.

[0036] In one embodiment, the proportional coefficient range, integral coefficient range, and derivative coefficient range corresponding to the adjustment direction are determined according to the preset mapping relationship between each coefficient range and related parameters. For example, if the adjustment direction is in the large deviation stage of the air supply state, the corresponding coefficient ranges are: Kp (0.8~1.2), Kd (0.3~0.5), Ki is 0; if the adjustment direction is in the small deviation stage of the air supply state, the corresponding coefficient ranges are: Kp (0.3~0.5), Kd (0.1~0.2), Ki (0.1~0.2); if the adjustment direction is in the large deviation stage of the exhaust state, the corresponding coefficient ranges are: Kp (0.7~0.9), Kd (0.4~0.6), Ki is 0; if the adjustment direction is in the small deviation stage of the exhaust state, the corresponding coefficient ranges are: Kp (0.3~0.5), Kd (0.05~0.1), Ki (0.1~0.2). The determined proportional coefficient range Kp is then used as the final range of proportional coefficient values ​​for calculation. Calculate the difference between the current pressure deviation and the historical average pressure deviation in the historical pressure parameters. If this difference exceeds a preset threshold, adjust the initially determined integral coefficient range downwards according to preset adjustment rules, with an adjustment interval of 0.15 kPa. Therefore, the boundary value of the Kd range can be adjusted downwards by 0.15 kPa to obtain the target integral coefficient range. Sum the current pressure deviation and all pressure deviations in the historical pressure parameters to obtain the cumulative integral value. Determine the preset cumulative integral value range to which this cumulative integral value belongs. Based on preset adjustment rules, determine the adjustment strategy corresponding to this preset cumulative integral value range. Adjust the initially determined integral coefficient range according to this adjustment strategy to obtain the target integral coefficient range.

[0037] This application embodiment determines the proportional coefficient range, integral coefficient range, and derivative coefficient range corresponding to the adjustment direction. Based on the current air pressure deviation value, the historical air pressure parameters, and the preset adjustment rules, the integral coefficient range or the derivative coefficient range is corrected to obtain the target integral coefficient range or the target derivative coefficient range. This can adapt to various dynamic change scenarios, eliminate static errors, suppress overshoot and oscillation, reduce energy waste caused by ineffective adjustment, lower operating costs, and significantly improve the energy efficiency of the exhaust system and user comfort.

[0038] Optionally, after periodically acquiring environmental parameters, the method further includes: if the oil fume concentration value in the environmental parameters is greater than a preset concentration threshold, adjusting the preset target air pressure range downward to obtain a first temporary target air pressure range; correspondingly, calculating the current air pressure deviation value based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in the preset target air pressure range, including: calculating the current air pressure deviation value based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in the first temporary target air pressure range.

[0039] The oil fume concentration value refers to the real-time value collected by the sensor that reflects the content of oil fume pollutants in the kitchen environment. The preset concentration threshold refers to a pre-set critical value of oil fume concentration used to determine whether the preset target air pressure range needs to be adjusted. The first temporary target air pressure range refers to a temporary air pressure control range formed after adaptively lowering the preset target air pressure range in special scenarios where the oil fume concentration in the kitchen exceeds the standard. In one embodiment, the oil fume concentration value collected by the sensor is periodically acquired. By comparing the oil fume concentration value with the preset concentration threshold, it is determined whether the preset target air pressure range needs to be adjusted. If the oil fume concentration value is greater than the preset concentration threshold, the preset target air pressure range is lowered to obtain the first temporary target air pressure range. The current air pressure deviation value is calculated based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in the first temporary target air pressure range. In another possible implementation, within a preset time period after obtaining the first temporary target air pressure range, the first temporary target air pressure range is restored to the preset target air pressure range.

[0040] In another possible embodiment, when it is detected that the air pressure fluctuation rate meets the corresponding preset threshold due to the opening of the air supply, such as air pressure fluctuation ≥10kPa / second, the exhaust speed is immediately increased by one level, such as from low speed to medium speed, to avoid excessive exhaust and air pressure imbalance. When it is detected that the air pressure fluctuation rate meets the corresponding preset threshold due to the closing of the air supply, the exhaust speed is decreased by one level, such as from high speed to medium speed, to prevent excessive negative pressure.

[0041] This application embodiment reduces the preset target air pressure range when the oil fume concentration value in the environmental parameters exceeds the preset concentration threshold to obtain a temporary target air pressure range. The current air pressure deviation value is calculated based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in the temporary target air pressure range. This can quickly remove heavy oil stains in special scenarios where oil fumes exceed the standard, while avoiding air pressure imbalance in the kitchen and fully ensuring user comfort.

[0042] Optionally, after periodically acquiring environmental parameters, the method further includes: if the oil fume concentration value in the environmental parameters is less than a preset concentration threshold and the actual air pressure value is less than a preset air pressure threshold, adjusting the preset target air pressure range upward to obtain a second temporary target air pressure range; extracting the midpoint air pressure value of the second temporary target air pressure range, calculating the target air pressure reference value based on the midpoint air pressure value, the preset reference air pressure, and the preset adjustment coefficient, and replacing the midpoint air pressure value in the preset target air pressure range with the target air pressure reference value; correspondingly, calculating the current air pressure deviation value based on the actual air pressure value in the environmental parameters and the midpoint air pressure value in the preset target air pressure range, including: calculating the current air pressure deviation value based on the actual air pressure value in the environmental parameters and the target air pressure reference value.

[0043] The target air pressure reference value refers to a standard air pressure value that is pre-set to achieve the preset equipment operating state and can be used as a reference for air pressure adjustment. The preset adjustment coefficient is an adjustment coefficient used to regulate the rate of change of air pressure in the kitchen. Figure 2 This is a schematic diagram of a pressure control range provided in an embodiment of this application, such as... Figure 2 As shown, in one embodiment, when the oil fume concentration value in the environmental parameters is less than a preset concentration threshold (i.e., in air supply mode) and the actual air pressure value is less than a preset minimum air pressure threshold (101325 Pa), to avoid excessive negative pressure, the preset target air pressure range needs to be adjusted upward to obtain a second temporary target air pressure range, and the midpoint air pressure value of the second temporary air pressure range is calculated. The target air pressure reference value is calculated based on this midpoint air pressure value, the preset reference air pressure value, and the preset adjustment coefficient. For example, if the midpoint air pressure value is 95000 Pa, the preset reference air pressure is 40000 Pa, and the preset adjustment coefficient is 2, the target air pressure reference value is calculated according to the adjustment formula as: 95000 + (40000 - 2) × 2 = 102996. After calculating the target air pressure reference value, the current air pressure deviation value is obtained by calculating the difference between the actual air pressure value in the environmental parameters and the target air pressure reference value. Based on the current air pressure deviation value and the preset PID algorithm, a control signal is generated to control the air pressure value in the kitchen within the range of R01 (101325pa~105000pa).

[0044] In the embodiment of the present application, when the oil fume concentration value in the environmental parameters is greater than the preset concentration threshold and the actual air pressure value is less than the preset air pressure threshold, the preset target air pressure range is lowered to obtain a second temporary target air pressure range, the midpoint air pressure value of the second temporary target air pressure range is extracted, the target air pressure reference value is calculated according to the midpoint air pressure value, the preset reference air pressure and the preset adjustment coefficient, and the midpoint air pressure value in the preset target air pressure range is replaced with the target air pressure reference value. The current air pressure deviation value is calculated according to the actual air pressure value and the target air pressure reference value in the environmental parameters, which can reduce the indoor-outdoor air pressure difference, reduce the risk of oil fume overflow, improve the smoke exhaust efficiency and the system response accuracy, maintain the indoor air flow stability while ensuring the safety of the user's breathing environment, and optimize the overall use experience.

[0045] In a possible embodiment, the current air pressure value can be collected once every preset time interval through the built-in air pressure sensor. If the current air pressure value is less than 101.325 kPa - 7 kPa, it is determined as a negative pressure state. If the current air pressure is greater than 101.325 kPa + 4 kPa, it is determined that the air supply is closed, and the result is displayed on the display screen. Among them, the time interval is greater than the acquisition period of the environmental parameters. For example, the time interval can be 10 s, and the acquisition period of the environmental parameters can be 4 s. The embodiment of the present application can also facilitate the subsequent direct determination of the adjustment direction by judging the initial indoor state through the above method.

[0046] In another possible embodiment, a power-on self-check is performed before periodically acquiring the environmental parameters and historical air pressure parameters, and test signals are sent to the built-in air pressure sensor, the exhaust air volume control module, the display screen and the indicator light respectively. If the air pressure detection sensor returns an initial value (error ≤ 5 kPa), the exhaust air volume can be smoothly switched (low / medium / high), and the controller screen lights up normally, the detection is qualified. If any hardware is abnormal, an exception is immediately triggered, and the display screen prompts the faulty component, such as "air pressure detection unit failure". The embodiment of the present application lays a foundation for subsequent air pressure control by detecting each device, and prevents potential safety hazards such as air pressure imbalance or excessive negative pressure in the cavity.

[0047] Figure 3 It is a flowchart of a method for determining a target differential coefficient interval provided by an embodiment of the present application, as Figure 3 shown, including: Step S201: Calculate the air pressure deviation change rate according to the adjacent deviation values, the current air pressure deviation value in the historical air pressure parameters and the preset sampling period.

[0048] Step S202: Modify the differential coefficient interval according to the air pressure deviation change rate and the preset adjustment rule to obtain the target differential coefficient interval.

[0049] The adjacent deviation value refers to the historical air pressure deviation value calculated in the previous sampling period immediately preceding the current sampling period, and can be denoted as e(k-1). The preset sampling period refers to a fixed time interval set in advance for the air pressure sensor to periodically collect ambient air pressure data and for the system to execute a complete adjustment logic, and can be denoted as Δt. The air pressure deviation change rate refers to the magnitude of change in the air pressure deviation value per unit time.

[0050] In one embodiment, the current pressure deviation is denoted as e(k), the adjacent deviation is denoted as e(k-1), the preset sampling period is denoted as Δt, and the pressure deviation change rate is denoted as v. The rate of change of air pressure deviation is compared with a corresponding preset rate of change range. If it is greater than the preset rate of change range, the differential coefficient range is adjusted downward; if it is less than the preset rate of change range, the differential coefficient range is adjusted upward. The adjustment interval is a preset interval included in the preset adjustment rules. After adjusting the differential coefficient range upward or downward based on this preset adjustment interval, the target differential coefficient range is obtained. Optionally, the preset sampling period is in the range of 50ms to 200ms, such as 100ms. This avoids a short sampling period, which can easily introduce noise when the sensor data is unstable, causing fluctuations in the control information frequency. It also avoids a long sampling period, which may fail to capture air pressure changes in time, leading to overshoot after the response.

[0051] This application embodiment calculates the rate of change of air pressure deviation based on adjacent deviation values ​​in historical air pressure parameters, the current air pressure deviation value, and a preset sampling period. It then corrects the differential coefficient range according to the rate of change of air pressure deviation and a preset adjustment rule to obtain the target differential coefficient range. This effectively suppresses oscillations and overshoots during air pressure regulation, ensuring that the air pressure quickly and smoothly approaches the preset target range. At the same time, it improves the adaptability of the PID algorithm to dynamic environments.

[0052] Figure 4 This is a flowchart of a method for determining a target integral coefficient interval provided in an embodiment of this application, such as... Figure 4 As shown, it includes: Step S301: If the absolute value of the deviation is less than or equal to the preset second deviation threshold, calculate the integral increment of the current cycle and the cumulative integral value of the integral increment and the historical sampling cycle integral value in the historical pressure parameters.

[0053] Step S302: If the accumulated integral value is greater than the preset integral threshold, stop the accumulation calculation of the integral value and determine the integral coefficient interval corresponding to the previous sampling period as the target integral coefficient interval.

[0054] The integral increment for the current period refers to the value reflecting the contribution of the pressure deviation to the integral term in this period. The historical sampling period integral value can refer to the cumulative value formed by adding the integral increments of all valid sampling periods prior to the current sampling period. The accumulated integral value can refer to the cumulative value obtained by superimposing the integral increment calculated in the current sampling period with the historical sampling period integral values ​​in the historical pressure parameters. The preset integral threshold can refer to a pre-set upper limit value for the cumulative integral effect, used to avoid excessive accumulation of the integral term in the PID algorithm, leading to integral saturation and thus causing pressure regulation overshoot.

[0055] In one embodiment, when the absolute value of the deviation is greater than a preset second deviation threshold, the control of the integral term in the PID algorithm on the output is paused, and only the proportional and derivative coefficients are used to adjust the output. Therefore, the integral coefficient is set to 0, which is unnecessary to consider. When the absolute value of the deviation is less than or equal to the preset second deviation threshold, the integral increment for the current period is first calculated as follows: Then, the integral increment is summed with the integral values ​​of the historical sampling periods in the historical pressure parameters to obtain the accumulated integral value, which is: , where i = 1 to k-1. In another possible embodiment, the cumulative integral of the current period's integral increment and the historical sampling period integral values ​​in the historical pressure parameters can also be directly calculated as: (i=1 to k). After calculating the accumulated integral value, the accumulated integral value is compared with the preset integration threshold to determine whether to stop the accumulation calculation. If the accumulated integral value is greater than the preset integration threshold, the accumulation calculation is stopped, and the integration coefficient interval corresponding to the previous sampling period is determined as the target integration coefficient interval.

[0056] This application embodiment calculates the integral increment of the current cycle and the cumulative integral value of the integral increment and the historical sampling cycle integral value in the historical air pressure parameters when the absolute value of the deviation is less than or equal to a preset second deviation threshold. When the cumulative integral value is greater than a preset integral threshold, the calculation of the integral value accumulation is stopped, and the integral coefficient interval corresponding to the previous sampling cycle is determined as the target integral coefficient interval. This can accurately eliminate static air pressure error while effectively avoiding regulation overshoot caused by integral saturation.

[0057] Figure 5 This is a flowchart illustrating a method for determining the current air pressure deviation value provided in an embodiment of this application, as shown below. Figure 5 As shown, it includes: Step S401: Calculate the pressure difference between the actual air pressure value in the environmental parameters and the previous adjacent actual air pressure value. If the pressure difference is less than or equal to a preset difference threshold, determine the actual air pressure difference as the current effective air pressure value.

[0058] Step S402: If the pressure difference is greater than the preset difference threshold, the actual pressure value is determined to be an invalid pressure value, and the previous adjacent actual pressure value is determined as the current valid pressure value.

[0059] Step S403: Calculate the current pressure deviation value based on the effective air pressure value and the midpoint air pressure value in the preset target air pressure range.

[0060] The preset difference threshold refers to a pre-set critical value used to determine the reasonableness of the difference between the current cycle's actual air pressure value and the previous adjacent actual air pressure value. The current valid air pressure value refers to reliable air pressure data used to calculate the current air pressure deviation value. The invalid air pressure value refers to the current cycle's actual air pressure value that deviates from the normal fluctuation range, is subject to interference, or is abnormal.

[0061] In one embodiment, the difference between the periodically collected actual air pressure value and the previous adjacent actual air pressure value included in the historical air pressure parameters is calculated to obtain the actual air pressure difference. This actual air pressure difference is compared with a preset threshold for reasonableness of the difference. If the actual air pressure difference is greater than the threshold, the collected actual air pressure value is considered to be interfered with, and therefore, this actual air pressure value is determined as an invalid air pressure value. The previous adjacent actual air pressure value in the historical air pressure parameters, that is, the previous adjacent effective air pressure value, is determined as the current effective air pressure value. After determining the current effective air pressure value, the difference between the current effective air pressure value and the midpoint air pressure value in the preset target air pressure range is calculated to obtain the current air pressure deviation value.

[0062] This application embodiment calculates the pressure difference between the actual air pressure value in the environmental parameters and the previous adjacent actual air pressure value. If the pressure difference is less than or equal to a preset difference threshold, the actual air pressure difference is determined as the current effective air pressure value. If the pressure difference is greater than the preset difference threshold, the actual air pressure value is determined as an invalid air pressure value, and the previous adjacent actual air pressure value is determined as the current effective air pressure value. The current air pressure deviation value is calculated based on the effective air pressure value and the midpoint air pressure value in the preset target air pressure range. This can ensure the reliability of air pressure data and the accuracy of the current air pressure deviation calculation by filtering abnormal interference data.

The control signal calculation module 54 is used to output a control signal based on the current air pressure deviation value, the target coefficient range, and the preset algorithm. The air pressure adjustment module 55 is used to adjust the actual air pressure value based on the control signal.
