Description

Technical Field

[0001] This application relates to the technical field of pressure relief control of electric pressure cookers. More specifically, it relates to a fast pressure relief method and system based on cloud response to emergency events. Background Art

[0002] The pressure control of traditional electric pressure cookers relies on the coordinated operation of a single sensor and a mechanical safety valve, which has systematic risks in pressure control. For example, the pressure control system of an electric pressure cooker may misjudge the pressure threshold due to sensor drift, thermostat failure, or circuit aging, making it difficult for the traditional PID pressure control algorithm to adapt to the non-linear pressure changes of the electric pressure cooker. In addition, existing pressure relief mechanisms mostly use fixed-aperture exhaust valves. In the face of sudden situations such as blocked exhaust channels and accumulated food residues, the pressure relief rate is limited and the response is lagged, unable to meet the dynamic pressure regulation requirements under emergency conditions. Moreover, problems such as structural integrity decline caused by long-term use, such as mechanical structure fatigue and seal ring aging, further exacerbate the risk of pressure out of control.

[0003] In the current electric pressure cooker pressure control technology, the ability to handle compound faults such as human misoperations is insufficient, and there is a lack of intelligent safety redundancy design. Electric pressure cooker products on the market generally adopt passive protection strategies and lack active prevention mechanisms for human errors such as overfilling with water and misplacing easily expandable ingredients. In addition, in the current electric pressure cooker control technology, although a multi-sensor fusion scheme has been proposed, there are still technical gaps in aspects such as real-time data processing, cloud-edge collaborative decision-making, and self-repair mechanisms, resulting in a poor comprehensive solution effect for pressure out-of-control events of electric pressure cookers and restricting the improvement of the safety performance of electric pressure cookers under complex working conditions.

[0023] In the current pressure control technology of electric pressure cookers, the comprehensive solution effect of electric pressure cookers for pressure out-of-control events is poor, which restricts the improvement of the safety performance of electric pressure cookers under complex working conditions.

[0024] For the above reasons, the embodiment of the present application provides a rapid pressure relief method based on emergency event cloud response. This method includes: obtaining the working parameter information of the electric pressure cooker, and determining the primary working parameters, secondary working parameters, and tertiary working parameters in the working parameter information; where the primary working parameters include the sequential pressure value of the electric pressure cooker, the secondary working parameters include the water injection amount and ingredient information of the electric pressure cooker, and the tertiary working parameters include the pressure relief speed value of the electric pressure cooker; when the primary working parameters meet the primary pressure relief condition, perform pressure relief on the electric pressure cooker through the primary pressure relief operation, and transmit the secondary working parameters to the edge computing unit; detect the secondary working parameters through the edge computing unit, when the secondary working parameters meet the secondary pressure relief condition, perform pressure relief on the electric pressure cooker through the secondary pressure relief operation, and send the tertiary working parameters to the cloud processing unit; detect the tertiary working parameters through the cloud processing unit, when the tertiary working parameters meet the tertiary pressure relief condition, perform pressure relief on the electric pressure cooker through the tertiary pressure relief operation; where the edge computing unit is provided in the electric pressure cooker, and the pressure relief speeds of the primary pressure relief operation, secondary pressure relief operation, and tertiary pressure relief operation increase in sequence.

[0025] In some scenarios, a rapid pressure relief method based on emergency event cloud response in the embodiment of the present application can be applied to the pressure control of an electric pressure cooker, especially suitable for the control of an electric pressure cooker based on Internet of Things control, and can improve the pressure relief control effect of the electric pressure cooker.

[0026] The following specifically describes a rapid pressure relief method based on emergency event cloud response provided by the embodiment of the present application with specific examples.

[0027] Figure 1 It is a schematic flowchart of the first rapid pressure relief method based on emergency event cloud response provided by the embodiment of the present application. As Figure 1 shown, the above method includes S110 to S120. The following specifically describes S110 to S120.

[0028] S110. Obtain the working parameter information of the electric pressure cooker, and determine the primary working parameters, secondary working parameters, and tertiary working parameters in the working parameter information. Among them, the primary working parameters include the sequential pressure value of the electric pressure cooker, the secondary working parameters include the water injection amount and ingredient information of the electric pressure cooker, and the tertiary working parameters include the pressure relief speed value of the electric pressure cooker.

[0029] The electric pressure cooker in the embodiments of the present application may include a pot body and a pot lid. An inner pot is provided inside the pot body, and a heating component is provided below the inner pot; a micro-pressure sealing ring is sleeved at the contact surface between the outer edge of the pot lid and the pot body, and a sealed space is formed between the pot body and the pot lid; the pot lid of the electric pressure cooker is further provided with an electronically controlled air release valve, and the opening degree of the electronically controlled air release valve can be controlled to control the pressure release speed of the electric pressure cooker. At the same time, the electric pressure cooker may further include a control component and a communication component. The control component is used to detect the working parameters and water injection amount of the electric pressure cooker, and collect the ingredient information input by the user. The communication component is used to communicate with the cloud control unit to control the pressure release state of the electric pressure cooker through the motion control component.

[0030] Exemplarily, the electric pressure cooker may include a variety of sensors. The sensors are used to obtain the working parameter information of the electric pressure cooker. Specifically, the sensors may include a pressure sensor, a water level sensor, a temperature sensor, etc.

[0031] Figure 2 It is a schematic diagram of the working process of the first rapid pressure release method based on cloud response to emergency events provided by the embodiments of the present application. As Figure 2 shown, in order to control the pressure release state of the electric pressure cooker, the working parameter information of the electric pressure cooker can be obtained, and the primary working parameter, secondary working parameter, and tertiary working parameter in the working parameter information can be determined. The primary working parameter, secondary working parameter, and tertiary working parameter are used to control different pressure release states of the electric pressure cooker.

[0032] It should be noted that the primary working parameter includes the sequential pressure value of the electric pressure cooker. Specifically, the pressure value inside the electric pressure cooker can be obtained through a pressure sensor.

[0033] It should be noted that the secondary working parameter may include the water injection amount and ingredient information of the electric pressure cooker. The water injection amount can be detected and obtained through a water level sensor, and the ingredient information can be obtained by the user inputting the cooking program corresponding to the ingredient information on the input panel.

[0034] It should be noted that the tertiary working parameter may include the pressure release speed value of the electric pressure cooker. The pressure release speed value can be obtained by detecting the pressure change value inside the electric pressure cooker.

[0035] S120. When the primary operating parameters meet the primary pressure relief condition, the electric pressure cooker is pressure-relieved through the primary pressure relief operation, and the secondary operating parameters are transmitted to the edge computing unit. The edge computing unit detects the secondary operating parameters. When the secondary operating parameters meet the secondary pressure relief condition, the electric pressure cooker is pressure-relieved through the secondary pressure relief operation, and the tertiary operating parameters are sent to the cloud processing unit. The cloud processing unit detects the tertiary operating parameters. When the tertiary operating parameters meet the tertiary pressure relief condition, the electric pressure cooker is pressure-relieved through the tertiary pressure relief operation. Among them, the edge computing unit is provided in the electric pressure cooker, and the pressure relief speeds of the primary pressure relief operation, the secondary pressure relief operation, and the tertiary pressure relief operation increase in sequence.

[0036] During pressure relief control, when the primary operating parameters meet the primary pressure relief condition, it indicates that the electric pressure cooker needs to be initially pressure-relieved. The electric pressure cooker is pressure-relieved through the primary pressure relief operation. For example, when the pressure value at a certain moment of the electric pressure cooker in the sequential pressure value of the primary operating parameters exceeds a preset sequential pressure threshold, the primary pressure relief operation can be triggered.

[0037] Exemplarily, the primary pressure relief operation can be to open the main pressure relief valve of the electric pressure cooker to relieve the pressure of the electric pressure cooker.

[0038] As Figure 2 shown, when the electric pressure cooker is pressure-relieved through the primary pressure relief operation, the secondary operating parameters can be transmitted to the edge computing unit, and the pressure relief requirement of the electric pressure cooker is detected through the secondary operating parameters to determine whether further pressure relief is required through the secondary pressure relief operation corresponding to the secondary operating parameters.

[0039] During pressure relief control after the primary pressure relief operation is triggered, the edge computing unit can also detect the secondary operating parameters. When the secondary operating parameters meet the secondary pressure relief condition, it indicates that the electric pressure cooker needs further pressure relief, and the electric pressure cooker can be pressure-relieved through the secondary pressure relief operation to ensure the pressure relief effect.

[0040] Exemplarily, when the water injection volume is too large or the ingredient information indicates that faster pressure relief is required, the secondary pressure relief operation can be triggered.

[0041] Exemplarily, the secondary pressure relief operation can include actively cooling the electric pressure cooker using a semiconductor heat dissipation component to quickly relieve the pressure.

[0042] As Figure 2 shown, when the electric pressure cooker is pressure-relieved through the secondary pressure relief operation, the tertiary operating parameters can be sent to the cloud processing unit to determine whether further pressure relief is required through the tertiary pressure relief operation corresponding to the tertiary operating parameters.

[0043] Exemplarily, the three - stage pressure relief operation can be to open the standby air outlet valve to relieve the pressure of the electric pressure cooker, and the two - stage pressure relief operation can also be to prompt the user to manually open the standby air outlet valve of the electric pressure cooker to relieve the pressure of the electric pressure cooker.

[0044] After triggering the two - stage pressure relief operation to relieve the pressure of the electric pressure cooker, the cloud processing unit can detect the three - stage working parameters. When the three - stage working parameters meet the three - stage pressure relief conditions, the electric pressure cooker can be relieved of pressure through the three - stage pressure relief operation to ensure the pressure relief effect.

[0045] Exemplarily, when emergency pressure relief is required or it is predicted according to historical data that faster pressure relief is needed, the three - stage pressure relief operation can be triggered.

[0046] It should be noted that the pressure relief speeds of the first - stage pressure relief operation, the second - stage pressure relief operation, and the third - stage pressure relief operation increase in sequence. Thus, the pressure relief speed of the electric pressure cooker can be ensured by the increasing pressure relief speeds in sequence, and the pressure relief effect of the electric pressure cooker can be guaranteed.

[0047] It should be noted that the edge computing unit can be set in the electric pressure cooker to process local data and perform a fast - response pressure relief operation.

[0048] It should be noted that the cloud processing unit is used to process complex data analysis and decision - making and perform a higher - level pressure relief operation.

[0049] The beneficial effect of the above implementation method is that this fast pressure relief method based on cloud response to emergency events, through a multi - stage pressure relief control mechanism, the emergency degree of pressure relief increases in sequence from the first - stage pressure relief operation, the second - stage pressure relief operation, and the third - stage pressure relief operation. Combining edge computing and cloud computing technologies, it realizes fast, safe, and intelligent pressure relief of the electric pressure cooker, improves the user experience, and ensures the safe use of the electric pressure cooker.

[0050] In some implementation methods, in S110 above, the first - stage pressure relief conditions include that the pressure increasing speed of the sequential pressure value is greater than or equal to the preset pressure increasing speed, the second - stage pressure relief conditions include that the water injection volume of the electric pressure cooker is greater than or equal to the preset water injection volume, and the ingredient information is the preset ingredient information, and the third - stage pressure relief conditions include that the pressure relief speed value is less than the preset pressure relief speed value.

[0051] When performing pressure relief control, the first - stage pressure relief conditions can include that the pressure increasing speed of the sequential pressure value is greater than or equal to the preset pressure increasing speed. Thus, when the increasing speed of the sequential pressure value is too high, it is determined that pressure relief control of the electric pressure cooker is required to initially improve the safety protection effect of the electric pressure cooker.

[0052] When performing pressure relief control, the secondary pressure relief condition may include that the water injection volume of the electric pressure cooker is greater than or equal to the preset water injection volume, and the ingredient information is the preset ingredient information. The preset ingredient information may be the ingredient category that requires enhanced pressure relief control. Thus, it can be determined that when the water injection volume is too large and the ingredient is the ingredient information that requires enhanced pressure relief control, and when the primary pressure relief condition is met, the electric pressure cooker can be further pressure relieved to further pressure relieve the electric pressure cooker through the secondary pressure relief operation.

[0053] When performing pressure relief control, the tertiary pressure relief condition may include that the pressure relief speed value is less than the preset pressure relief speed value. When performing pressure relief through the secondary pressure relief operation, the pressure relief speed of the electric pressure cooker may be affected by the failure of the electric pressure cooker. Thus, the pressure relief speed of the electric pressure cooker can be detected to further ensure the pressure relief speed of the electric pressure cooker and improve the use safety of the electric pressure cooker.

[0054] In some implementation manners, the above method further includes S130 to S140, which are specifically described below.

[0055] S130: Through the pressure relief speed decision model, determine the first weight corresponding to the primary pressure relief condition and the second weight corresponding to the secondary pressure relief condition according to the pressure increase speed, the water injection volume of the electric pressure cooker, and the ingredient information.

[0056] When further performing pressure relief control, in order to improve the pressure relief speed, the pressure relief speed decision model can be executed by the processor of the electric pressure cooker. First, the current pressure increase speed can be obtained through the pressure sensor, the water injection volume of the electric pressure cooker can be obtained through the water level sensor, and the ingredient information can be obtained. Further, the above parameters can be synchronously transmitted to the pressure relief speed decision model. The pressure relief speed decision model can generate the first weight corresponding to the primary pressure relief condition and the second weight corresponding to the secondary pressure relief condition respectively based on the preset weight calculation rule. Thus, the urgency of the pressure relief operation can be further judged according to the pressure increase speed, the water injection volume of the electric pressure cooker, and the ingredient information to improve the pressure relief effect inside the electric pressure cooker.

[0057] Exemplarily, the pressure change rate (ΔP / Δt) inside the electric pressure cooker can be monitored in real time through the built-in pressure sensor, combined with the water injection volume (V) obtained by the water level sensor and the ingredient type information input by the user (such as meat, grains, or vegetables) to construct a multi-dimensional feature vector. After the feature vector is normalized, it is input into the pressure relief speed decision model, and the weighted algorithm is used to calculate the first weight (W1) corresponding to the primary pressure relief condition and the second weight (W2) corresponding to the secondary pressure relief condition respectively, where W1 = α1·(ΔP / Δt)+β1·V+γ1·M, W2 = α2·(ΔP / Δt)+β2·V+γ2·M, α, β, γ are preset coefficients, and M is the density matrix value corresponding to the ingredient type.

[0058] S140. When the first weight is greater than or equal to the second weight, and when the primary operating parameters meet the primary pressure relief condition, the pressure cooker is depressurized through the primary pressure relief operation, and the secondary operating parameters are transmitted to the edge computing unit. The edge computing unit detects the secondary operating parameters. When the secondary operating parameters meet the secondary pressure relief condition, the pressure cooker is depressurized through the secondary pressure relief operation, and the tertiary operating parameters are sent to the cloud processing unit. When the first weight is less than the second weight, and when the primary operating parameters meet the primary pressure relief condition, the pressure cooker is depressurized through the secondary pressure relief operation, and the tertiary operating parameters are sent to the cloud processing unit.

[0059] During pressure relief control, when the processor determines that the first weight coefficient ≥ the second weight coefficient, and when the primary operating parameters meet the primary pressure relief condition, that is, when W1 ≥ W2, the system enters the hierarchical pressure relief mode. Specifically, the primary pressure relief operation can be triggered, and then the pressure is released at a preset pressure relief rate. During the primary pressure relief operation, the secondary operating parameters can be further transmitted to the edge computing unit for real-time detection. The edge computing unit further determines whether a secondary pressure relief operation is required to ensure normal pressure relief of the pressure cooker.

[0060] During pressure relief control, when the processor determines that the first weight coefficient < the second weight coefficient, and when the primary operating parameters meet the primary pressure relief condition, the secondary pressure relief operation can be directly triggered at this time. The secondary pressure relief operation can quickly reduce the pressure inside the pot at a preset pressure relief rate.

[0061] It should be noted that regardless of the pressure relief path adopted, when the pressure inside the pot drops to the safety threshold, the processor can close all pressure relief valves through the actuator and enter the pressure-holding cooking stage. The edge computing unit continuously monitors the pressure stability during the pressure-holding stage. When it detects that the pressure fluctuation exceeds the allowable range, the secondary pressure relief operation can be further automatically started for pressure relief.

[0062] The beneficial effect of the above implementation method is that by further judging the urgency of the pressure relief operation based on the pressure increase speed, the water injection volume of the pressure cooker, and the ingredient information, and when the primary operating parameters meet the primary pressure relief condition, the pressure cooker is depressurized according to the primary pressure relief operation or the secondary pressure relief operation, which can improve the pressure relief effect inside the pressure cooker.

[0063] In some implementation methods, the above method further includes S150 to S160, which are specifically described below.

[0064] S150. Count the number of secondary pressure relief operations corresponding to the pressure cooker during a preset first time period.

[0065] In pressure relief control, the timer built into the electric pressure cooker control module can be used to count in real time the number of secondary pressure relief operations N performed within a preset first time period (e.g., a 30-minute cooking cycle). The counting of the number of secondary pressure relief operations is based on the timestamp data in the pressure relief event log. Each time a secondary pressure relief operation is triggered, the event time and the corresponding pressure parameters (e.g., pressure relief rate and termination pressure value) can be recorded in the memory.

[0066] Exemplarily, the preset first time period can be dynamically adjusted according to the type of ingredients (e.g., extended to 45 minutes for meat cooking and shortened to 20 minutes for porridge).

[0067] S160. When the number of secondary pressure relief operations is greater than or equal to the preset number of secondary pressure relief operations, and the secondary working parameters meet the secondary pressure relief conditions, the electric pressure cooker is pressure-relieved through a tertiary pressure relief operation.

[0068] In pressure relief control, when it is detected that the number of secondary pressure relief operations N reaches or exceeds the preset number of secondary pressure relief operations (e.g., N ≥ 3 times), it indicates that the number of secondary pressure relief operations is too large and there may be a pressure relief failure in the electric pressure cooker. And when the currently collected secondary working parameters simultaneously meet the secondary pressure relief conditions, it indicates that a secondary pressure relief operation needs to be performed again. The electric pressure cooker can automatically activate a tertiary pressure relief operation to increase the pressure relief speed of the electric pressure cooker.

[0069] Exemplarily, the preset number of secondary pressure relief operations can also be negatively correlated with the volume of the pressure vessel (e.g., N = 2 times for a 5L pot body and N = 4 times for a 3L pot body). The execution log of the tertiary pressure relief operation can also be associated with the unique device identification code, and the cloud server can build a cross-device pressure relief failure knowledge graph based on this.

[0070] The beneficial effect of the above implementation method is that when the number of secondary pressure relief operations within the preset first time period is too large and there may be a pressure relief failure in the electric pressure cooker, a tertiary pressure relief operation can be further performed on the electric pressure cooker during subsequent secondary pressure relief operations to quickly relieve the pressure, improving the pressure relief protection effect of the electric pressure cooker.

[0071] In some implementation methods, the above method further includes S170 to S180, which are specifically described below.

[0072] S170. Count the number of tertiary pressure relief operations corresponding to the tertiary pressure relief operations performed by the electric pressure cooker within a preset second time period.

[0073] In pressure relief control, the pressure relief event recording unit of the electric pressure cooker control module can also be used to count in real time the number of times K of the third-level pressure relief operations triggered within a preset second time period (for example, within 7 consecutive cooking cycles or within a cumulative operation of 12 hours). The counting can be based on the pressure relief operation logs, and each log contains a timestamp, a pressure relief duration, and peak pressure data.

[0074] S180. When the number of times of the third-level pressure relief is greater than or equal to the preset number of times of the third-level pressure relief, a cleaning prompt message for prompting to clean the exhaust valve of the electric pressure cooker is sent.

[0075] In pressure relief control, when it is detected that the cumulative number of times K reaches or exceeds the preset threshold (for example, K≥5 times), the system can trigger and send a cleaning prompt message to prompt the user to clean the electric pressure cooker.

[0076] Exemplarily, the cleaning prompt message can include a hierarchical alarm strategy. The primary alarm is presented as an orange flash by the LED indicator on the cooker body, and a voice prompt "It is recommended to clean the exhaust valve" is generated; if the cleaning operation is not performed within 72 hours and the number of times of the third-level pressure relief is still large (the number of times of the third-level pressure relief K is still greater than 2 times / cooking cycle), it is upgraded to an emergency alarm, triggering the device status locking function to restrict the start of the high-pressure cooking mode. At the same time, a strong reminder notice including a cleaning tutorial video is pushed to the user's mobile phone APP through the wireless communication module.

[0077] The beneficial effect of the above implementation manner is that by counting the number of times of the third-level pressure relief corresponding to the third-level pressure relief operation performed by the electric pressure cooker within the preset second time period, when the number of times of the third-level pressure relief exceeds the threshold, a cleaning prompt message for prompting to clean the exhaust valve of the electric pressure cooker is sent to prompt the user to clean, which can further improve the safety during the use of the electric pressure cooker.

[0078] Figure 3 The flowchart of the second rapid pressure relief method based on emergency event cloud response provided by the embodiment of the present application is shown as Figure 3 shown. The above method further includes S210 to S220, and the following is a specific description of S210 to S220.

[0079] S210. Obtain the first moment value detected by the edge computing unit for the secondary working parameters, and start timing from the first moment value as the edge detection response duration.

[0080] To improve the response speed of the pressure relief control, the built-in clock chip of the edge computing unit can be used to record the first moment value T1 when receiving the secondary working parameter detection instruction, and start a timer to accumulate the edge detection response duration Δt. The edge detection response duration represents the judgment duration for determining whether a secondary pressure relief operation needs to be performed by the edge computing unit.

[0081] S220. When the edge detection response duration is greater than or equal to the preset edge detection response duration, obtain the instruction of the historical secondary pressure relief operation stored in the electric pressure cooker and perform pressure relief on the electric pressure cooker.

[0082] During the pressure relief judgment process, when it is detected that the edge detection response duration Δt reaches or exceeds the preset edge detection response duration threshold (for example, Δt≥5s), it indicates that the time for determining whether to perform the secondary pressure relief operation through the edge computing unit is too long, which may cause the pressure of the electric pressure cooker not to be released in time and pose a danger. At this time, the historical instruction call mechanism can be triggered to retrieve the instruction of the historical secondary pressure relief operation stored in the non-volatile memory of the electric pressure cooker locally and perform pressure relief on the electric pressure cooker.

[0083] Exemplarily, when performing pressure relief on the electric pressure cooker through the instruction of the historical secondary pressure relief operation, the instruction set of the historical secondary pressure relief operation for the most recent N times (for example, N = 5 times) can be obtained. The instruction set of the historical secondary pressure relief operation includes the pressure relief rate setting value, the valve opening curve, and the corresponding pressure safety margin parameter.

[0084] After obtaining the instruction set of the historical secondary pressure relief operation, the electric pressure cooker can screen out the historical records of the historical secondary pressure relief operation with the current water injection volume of the electric pressure cooker exceeding 10% through the dynamic priority algorithm, and then match the current pressure change mode based on the similarity model, and select the historical instruction of the historical secondary pressure relief operation with the highest matching degree for pressure relief.

[0085] Exemplarily, the preset edge detection response duration can be dynamically adjusted according to the working mode of the electric pressure cooker, set to 5s in the high-pressure cooking stage, and extended to 10s in the heat preservation stage.

[0086] Exemplarily, the historical secondary pressure relief operation can adopt a rolling update mechanism to retain the valid data for the most recent 30 days and automatically eliminate the historical records of the historical secondary pressure relief operation with a matching success rate lower than 60%.

[0087] The beneficial effect of the above implementation method is that it can judge whether the time for determining whether to perform the secondary pressure relief operation through the edge computing unit is too long, thereby avoiding the danger caused by the pressure of the electric pressure cooker not being released in time and improving the pressure relief speed of the electric pressure cooker.

[0088] In some implementation methods, the above method further includes S230 to S240, which will be specifically described below.

[0089] S230. Obtain the second moment value when the electric pressure cooker sends the three-level working parameters to the cloud processing unit, and start timing from the second moment value as the cloud response duration.

[0090] In the pressure relief control of the electric pressure cooker, the timestamp recording unit of the communication module of the electric pressure cooker can also record the second time value T2 when the three-level working parameters are successfully sent to the cloud processing unit, and start a timer to accumulate the cloud response duration Δtc. The cloud response duration Δtc represents the time length for the cloud processing unit to judge whether the electric pressure cooker needs to perform three-level pressure relief operation.

[0091] S240. When the cloud response duration is greater than or equal to the preset cloud response duration, obtain the instruction of the historical three-level pressure relief operation stored in the electric pressure cooker, and perform pressure relief on the electric pressure cooker through the instruction of the historical three-level pressure relief operation.

[0092] When detecting the cloud response duration, when it is detected that the cloud response duration Δtc reaches or exceeds the preset cloud response duration (for example, Δtc≥8s), it means that the time for the cloud processing unit to judge whether the electric pressure cooker needs to perform three-level pressure relief operation is too long. Then, the instructions of the last M (such as M = 3 times) effective historical three-level pressure relief operations can be retrieved from the non-volatile memory of the electric pressure cooker locally, and the electric pressure cooker is pressure-relieved through the instructions of the historical three-level pressure relief operation.

[0093] Exemplarily, when obtaining the instruction of the historical three-level pressure relief operation stored in the electric pressure cooker, the system can screen applicable instructions through the spatio-temporal similarity algorithm. First, the historical records with the environmental temperature difference exceeding ±5°C can be excluded, and then the current pressure curve shape is matched based on the dynamic time warping (DTW) algorithm, and the instruction of the historical three-level pressure relief operation with the minimum matching error is selected to perform pressure relief on the electric pressure cooker.

[0094] Exemplarily, the preset cloud response duration can be dynamically adjusted according to the network quality, set to 8s in the 5G network environment, and can be extended to 12s in the 4G environment.

[0095] The beneficial effect of the above implementation is that when the time for the cloud processing unit to judge whether the electric pressure cooker needs to perform three-level pressure relief operation is too long, the electric pressure cooker can be pressure-relieved through the historical three-level pressure relief operation stored in history, which improves the pressure relief safety of the electric pressure cooker.

[0096] In some implementation manners, in S220 above, obtaining the instruction of the historical secondary pressure relief operation stored in the electric pressure cooker to perform pressure relief on the electric pressure cooker includes S221 to S222, and the following specifically describes S221 to S222.

[0097] S221. Obtain the historical water injection amount and historical ingredient information corresponding to the instruction of the historical pressure relief operation stored in the electric pressure cooker, and determine the difference between the historical water injection amount and the water injection amount as the water injection amount difference.

[0098] When obtaining the instruction of the historical secondary pressure relief operation stored in the electric pressure cooker to perform pressure relief on the electric pressure cooker, the electric pressure cooker control module can call the locally stored historical secondary pressure relief instruction database, extract the historical operation record associated with the current pressure relief task, and perform pressure relief. When performing pressure relief control, the historical water injection volume Vhist corresponding to the instruction of the historical pressure relief operation stored in the electric pressure cooker can be obtained, the historical ingredient type code Mhist corresponding to the historical ingredient information can be obtained, and at the same time, the water injection volume Vcurr obtained by the water level sensor can be used as the water injection volume, and then the water injection volume difference ΔV = |Vhist - Vcurr| can be calculated.

[0099] S222. When the water injection volume difference is less than the preset water injection volume difference and the historical ingredient information is the same as the ingredient information, perform pressure relief on the electric pressure cooker through the instruction of the historical secondary pressure relief operation stored in the electric pressure cooker.

[0100] After obtaining the water injection volume difference, when the water injection volume difference is less than the preset water injection volume difference (for example, ΔV = ±100 ml or 5% volume ratio), it indicates that the difference between the water injection volume in the electric pressure cooker and the historical water injection volume is small, and when the historical ingredient information is the same as the ingredient information, it indicates that the pressure characteristics corresponding to the historical ingredient information are similar. Therefore, the electric pressure cooker can be pressure-relieved through the instruction of the historical secondary pressure relief operation stored in the electric pressure cooker.

[0101] The beneficial effect of the above implementation method is that when the difference between the water injection volume in the electric pressure cooker and the historical water injection volume is small, and the historical ingredient information is the same as the ingredient information, it indicates that the pressure characteristics in the electric pressure cooker are relatively similar. Therefore, the electric pressure cooker can be pressure-relieved through the instruction of the historical secondary pressure relief operation stored in the electric pressure cooker, so as to improve the judgment accuracy of using the historical secondary pressure relief operation for pressure relief.

[0102] In some implementation methods, the above method further includes: presetting the duration of the edge detection response duration to be 5 to 10 times the duration of the preset cloud response duration.

[0103] When controlling the pressure of the electric pressure cooker, the duration of the preset edge detection response duration can be controlled to be 5 to 10 times the duration of the preset cloud response duration, so that the response speed of performing pressure relief on the electric pressure cooker through the historical tertiary pressure relief operation is greater than the response speed of performing pressure relief on the electric pressure cooker through the historical secondary pressure relief operation, and the pressure relief speed of the electric pressure cooker in a more urgent situation is improved.

[0104] Exemplarily, the preset cloud response duration can be 8 s, and the preset edge detection response duration can be 1 s.

[0105] The beneficial effect of the above implementation method is that the response speed of relieving pressure on the electric pressure cooker through historical three - stage pressure relief operation is greater than that through historical two - stage pressure relief operation, ensuring the pressure relief safety of the electric pressure cooker in case of emergency.

[0106] Figure 4 FIG. is a schematic flow chart of the third rapid pressure relief method based on emergency event cloud response provided by the embodiment of the present application. As Figure 4 shown, the above method further includes S310 to S320, and the following is a specific description of S310 to S320.

[0107] S310: When relieving pressure on the electric pressure cooker through three - stage pressure relief operation, determine the pressure relief speed change characteristics of the electric pressure cooker according to the pressure relief speed value of the electric pressure cooker.

[0108] During the execution of the three - stage pressure relief operation, the pressure relief speed value v(t) can be collected in real time through a high - frequency pressure sensor, and time - domain segmentation processing is performed on it. The pressure relief process is divided into N time windows (for example, each window is 3 seconds). The average value vavg, variance σ², and change rate dv / dt of the pressure relief speed are calculated within each window. A pressure relief speed change feature vector F = [vavg, σ², dv / dt] is constructed, and the energy distribution characteristics of each frequency band are extracted using the wavelet packet transform algorithm. Combining the preset pressure relief stage division criteria (such as the initial rapid - drop period, stable period, and end period), a three - dimensional feature map representing the current pressure relief dynamic characteristics is generated.

[0109] S320: According to the pressure relief speed change characteristics of the electric pressure cooker, determine the preset water injection amount adjustment value for the two - stage pressure relief condition of the electric pressure cooker, transmit the preset water injection amount adjustment value for the two - stage pressure relief condition to the edge computing unit of the electric pressure cooker, and replace the preset water injection amount in the two - stage pressure relief condition with the preset water injection amount adjustment value.

[0110] After obtaining the pressure relief speed change characteristics, the water injection amount adjustment value ΔVadj for the two - stage pressure relief condition can be calculated through a pre - trained random forest regression model. The model input includes the current pressure relief speed feature vector F, and the calculation formula for the output water injection amount adjustment value ΔVadj can be: ΔVadj = α·vavg + β·(σ² / τ) + γ·Tenv, where α, β, and γ represent the weight parameters of the model, τ represents the time window length, and Tenv represents the measured value of the ambient temperature sensor.

[0111] Exemplarily, the adjusted preset water injection amount can be calculated by the following formula: Vnew = Vorig ± ΔVadj, where Vorig represents the preset water injection amount before adjustment, and Vnew represents the preset water injection amount adjustment value.

[0112] The beneficial effect of the above implementation manner is that when the pressure cooker is depressurized through three-stage pressure relief operation, according to the pressure relief speed change characteristics of the pressure cooker, the preset water injection amount adjustment value of the second-stage pressure relief condition of the pressure cooker is determined, realizing the adjustment of the preset water injection amount in the second-stage pressure relief condition according to the three-stage pressure relief operation, and enabling the pressure cooker to be depressurized in advance through the second-stage pressure relief operation before the three-stage pressure relief operation, further improving the pressure relief safety of the pressure cooker.
