Description

Technical Field

[0001] This invention relates to the field of intelligent control technology for building doors and windows, specifically to an intelligent sealing and energy-saving control method and system for a 70-type thermally broken aluminum alloy door and window. Background Technology

[0002] Type 70 thermally broken aluminum alloy doors and windows are widely used in residential, office, and other building envelopes due to their combination of structural strength, thermal insulation performance, and architectural adaptability. For this type of door and window, a good circumferential seal is typically required after the door / window sash and frame are closed to reduce air infiltration and maintain a suitable indoor environment.

[0003] Existing doors and windows typically achieve sash and frame compression and sealing through locking components and circumferential sealing strips. Some doors and windows also incorporate micro-ventilation structures to create a ventilation path when the doors and windows are closed, thus balancing ventilation needs with ease of use. This type of solution usually focuses on the overall locking and sealing coordination.

[0004] However, when the sealing status of different circumferential positions of doors and windows differs, existing solutions usually cannot detect different circumferential positions separately in the locked state and implement local compensation based on the detection results. Therefore, it is difficult to accurately determine the location and extent of leakage, and it is also difficult to switch to micro-ventilation state after the sealing status meets the requirements. Consequently, it is difficult to balance the sealing performance of doors and windows with the energy-saving ventilation requirements. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent sealing and energy-saving control method and system for 70-type thermally broken aluminum alloy doors and windows, so as to solve the problem that existing door and window solutions are difficult to perform zone detection and local compensation of the sealing status at different positions around the door and window, thus making it difficult to balance sealing performance and micro-ventilation requirements.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a smart sealing and energy-saving control method for 70-type thermally broken aluminum alloy doors and windows, comprising the following steps: S1. Obtain the locking status signal of the door and window. After confirming that the door and window sash and the door and window frame have reached the locking status, control the opening and closing parts of the micro ventilation bypass component to close, and control the top pressing parts of each auxiliary pressing component to be in the retracted position. S2. The control branch switching unit sequentially connects the detection branches corresponding to each detection section of the circumferential detection air chamber, performs pressure maintenance detection on each detection section, and obtains the pressure decay parameters corresponding to each detection section. The detection sections are set up circumferentially along the doors and windows. S3. Compare the pressure decay parameters corresponding to each detection section with the leakage judgment threshold to determine the target leakage section, and determine the first-level compensation, second-level compensation or third-level compensation corresponding to each target leakage section according to the pressure decay parameter range of each target leakage section. The first-level compensation, second-level compensation and third-level compensation correspond to different pressure decay parameter ranges. S4. Control the operation of the auxiliary clamping component corresponding to the target leakage section, so that its top pressure component moves from the retracted position to the compensation position corresponding to the corresponding sealing insufficiency level. The auxiliary clamping component corresponding to the detection section that is not identified as the target leakage section keeps the top pressure component in the retracted position. S5. After completing the partial compensation, perform pressure maintenance testing again on the target leakage section or all detection sections to obtain the pressure attenuation parameters after compensation. S6. When the retested pressure decay parameter is not higher than the leakage judgment threshold, control the corresponding auxiliary clamping component to keep the top pressure component in the current compensation position; when the retested pressure decay parameter is higher than the leakage judgment threshold, control the top pressure component of the corresponding target leakage section to move to the next compensation position, and repeat step S5 until the retested pressure decay parameter is not higher than the leakage judgment threshold or the highest compensation position is reached. S7. When the retested pressure attenuation parameters of all detection sections are not higher than the leakage judgment threshold, control the opening and closing parts of the micro ventilation bypass component to switch to the micro ventilation position; when the retested pressure attenuation parameter of any target leakage section is still higher than the leakage judgment threshold after reaching the highest compensation position, output an abnormal maintenance signal and control the opening and closing parts of the micro ventilation bypass component to remain in the closed position or the limited opening position.

[0007] Preferably, the locking state signal consists of a locking component in position signal and a door / window sash and door / window frame in contact signal; when both the locking component in position signal and the contact signal are present, it is determined that the door / window sash and door / window frame have reached the locking state.

[0008] Preferably, the detection sections include an upper frame detection section, a lower frame detection section, a hinge side detection section, and a locking side detection section.

[0009] Preferably, each detection section is sequentially connected to the corresponding detection branch through the branch switching unit to perform pressure holding detection; the pressure attenuation parameter is determined based on the initial pressure value, the pressure change value during the holding stage, and the final pressure value of each detection section.

[0010] Preferably, when there are multiple target leakage sections, the compensation order is determined according to the pressure attenuation parameter from largest to smallest.

[0011] Preferably, the insufficient sealing levels include first-level compensation, second-level compensation, and third-level compensation, with each level corresponding to a different compensation position. The compensation positions corresponding to the first-level compensation, second-level compensation, and third-level compensation are arranged in ascending order of compensation amount. Each auxiliary pressing component keeps the top pressing member in the retracted position when the door or window is in the open state or not in the locked state.

[0012] In order to realize the above-mentioned intelligent sealing and energy-saving control method, this embodiment also provides an intelligent sealing and energy-saving control system for a 70-type thermally broken aluminum alloy door and window, including a door and window frame, a door and window sash, a locking assembly, a circumferential sealing assembly, a pressure supply unit, a pressure detection unit, a branch switching unit, multiple auxiliary pressing assemblies, a micro-ventilation bypass assembly, and a controller. The circumferential sealing assembly is disposed in the circumferential direction of the door and window frame and the door and window sash. The circumferential sealing assembly includes a first sealing strip and a second sealing strip. The first sealing strip and the second sealing strip form a circumferential detection air chamber after the door and window sash is locked. The circumferential detection air chamber is divided into multiple detection sections along the circumference of the door and window by multiple partitions. Each detection section is connected to the detection branch through an independent branch channel. The branch switching unit, pressure supply unit and pressure detection unit are set on the detection branch. Multiple auxiliary clamping components are provided in a one-to-one correspondence with multiple detection sections. Each auxiliary clamping component is located inside the door or window frame or inside the door or window sash of the corresponding detection section. Each auxiliary clamping component includes a pressing member located on the back side of the corresponding sealing strip. The pressing member can switch between a retracted position and multiple compensation positions. The micro-ventilation bypass component is installed inside the upper frame or side frame of the door and window frame. The micro-ventilation bypass component includes a bypass air duct, an opening and closing device installed on the bypass air duct, and an isolation wall installed between the bypass air duct and the circumferential detection air chamber. The controller is connected to the interlocking assembly, branch switching unit, pressure supply unit, pressure detection unit, each auxiliary pressing assembly, and micro-ventilation bypass assembly.

[0013] Preferably, the detection sections include an upper frame detection section, a lower frame detection section, a hinge side detection section, and a locking side detection section, with adjacent detection sections separated by the partition.

[0014] Preferably, each auxiliary clamping component includes a pressing member, a driving member, and a resetting member. The driving member is connected to the pressing member in a driving manner, the resetting member is connected to the pressing member, and the pressing member can switch between a retracted position and multiple compensation positions corresponding to different compensation levels.

[0015] Preferably, the opening and closing element can switch between a closed position, a micro-ventilation position, and a limited opening position.

[0016] Compared with existing technologies, the intelligent sealing and energy-saving control method for a type 70 thermally broken aluminum alloy door and window, which adopts the above technical solution, has the following beneficial effects: First, by setting up a circumferential detection air chamber surrounded by a first sealing strip and a second sealing strip, and dividing the circumferential detection air chamber into multiple detection sections along the circumference of the door and window through multiple partitions, and then cooperating with the branch switching unit, pressure supply unit and pressure detection unit to perform pressure holding detection on each detection section, the controller can obtain the pressure decay parameters corresponding to each detection section and determine the target leakage section accordingly, thereby realizing the zonal identification of the sealing status of different positions of the door and window in the circumference; Second, by setting multiple auxiliary clamping components to correspond one-to-one with multiple detection sections, and determining first-level compensation, second-level compensation or third-level compensation according to the pressure attenuation parameter range corresponding to the target leakage section, and then controlling the top pressure component of the corresponding auxiliary clamping component to enter the corresponding compensation position, different detection sections can obtain local compensation corresponding to their degree of insufficient sealing, thereby achieving targeted compensation based on the zonal detection results. Third, in addition, by performing pressure maintenance detection again after local compensation, and controlling the opening and closing parts of the micro ventilation bypass component to switch to the micro ventilation position only when the retested pressure decay parameters of all detection sections are not higher than the leakage judgment threshold; when the retested pressure decay parameters of any target leakage section are still higher than the leakage judgment threshold after reaching the highest compensation position, an abnormal maintenance signal is output, and the opening and closing parts are controlled to remain in the closed position or the limit opening position, so that the micro ventilation switching is based on the retest meeting the standard.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example 1 like Figures 1-3 As shown, a smart sealing and energy-saving control method for a type 70 thermally broken aluminum alloy door and window includes the following steps: S1. Obtain the locking status signal of the door and window. After confirming that the door and window sash and the door and window frame have reached the locking status, control the opening and closing parts of the micro ventilation bypass component to close, and control the top pressing parts of each auxiliary pressing component to be in the retracted position. S2. The control branch switching unit sequentially connects the detection branches corresponding to each detection section of the circumferential detection air chamber, performs pressure maintenance detection on each detection section, and obtains the pressure decay parameters corresponding to each detection section. The detection sections are set up circumferentially along the doors and windows. S3. Compare the pressure decay parameters corresponding to each detection section with the leakage judgment threshold to determine the target leakage section, and determine the first-level compensation, second-level compensation or third-level compensation corresponding to each target leakage section according to the pressure decay parameter range of each target leakage section. The first-level compensation, second-level compensation and third-level compensation correspond to different pressure decay parameter ranges. S4. Control the operation of the auxiliary clamping component corresponding to the target leakage section, so that its top pressure component moves from the retracted position to the compensation position corresponding to the corresponding sealing insufficiency level. The auxiliary clamping component corresponding to the detection section that is not identified as the target leakage section keeps the top pressure component in the retracted position. S5. After completing the partial compensation, perform pressure maintenance testing again on the target leakage section or all detection sections to obtain the pressure attenuation parameters after compensation. S6. When the retested pressure decay parameter is not higher than the leakage judgment threshold, control the corresponding auxiliary clamping component to keep the top pressure component in the current compensation position; when the retested pressure decay parameter is higher than the leakage judgment threshold, control the top pressure component of the corresponding target leakage section to move to the next compensation position, and repeat step S5 until the retested pressure decay parameter is not higher than the leakage judgment threshold or the highest compensation position is reached. S7. When the retested pressure attenuation parameters of all detection sections are not higher than the leakage judgment threshold, control the opening and closing parts of the micro ventilation bypass component to switch to the micro ventilation position; when the retested pressure attenuation parameter of any target leakage section is still higher than the leakage judgment threshold after reaching the highest compensation position, output an abnormal maintenance signal and control the opening and closing parts of the micro ventilation bypass component to remain in the closed position or the limited opening position.

[0022] The door and window body includes a door and window frame, door and window sash, locking assembly, circumferential sealing assembly, detection branch, branch switching unit, pressure supply unit, pressure detection unit, auxiliary pressing assembly, micro ventilation bypass assembly and controller.

[0023] The circumferential sealing assembly is set in the circumferential direction of the door and window frame and the door and window sash. The circumferential sealing assembly includes a first sealing strip and a second sealing strip. After the door and window sash is locked, the first sealing strip and the second sealing strip form a circumferential detection air chamber.

[0024] The circumferential detection chamber is divided into multiple separate detection sections along the circumference of the doors and windows through the partition. Each detection section is connected to the detection branch through an independent branch channel.

[0025] The auxiliary clamping components are set one-to-one with the detection sections, and the top pressure component of the auxiliary clamping components is located on the back side of the corresponding sealing strip.

[0026] The micro-ventilation bypass component is installed inside the upper frame or side frame of the door or window frame. The micro-ventilation bypass component includes a bypass duct, an opening and closing element, and an isolation wall. The isolation wall is installed between the bypass duct and the circumferential detection air chamber.

[0027] The controller is connected to the interlocking assembly, branch switching unit, pressure supply unit, pressure detection unit, each auxiliary clamping assembly, and micro-ventilation bypass assembly, and is used to perform interlocking confirmation, zone detection, compensation level determination, local compensation, retesting, and micro-ventilation position switching.

[0028] In step S1, the locking status signal consists of a locking component positioning signal and a door / window sash and door / window frame fitting signal. The locking component can adopt a multi-point locking structure, with detection elements installed at the handle drive termination position, the locking point linkage termination position, or the position where the lock tongue and lock seat are fully locked; when all locking points have completed the locking action, the detection elements output a locking component positioning signal.

[0029] The signal indicating that the door / window sash and the door / window frame are properly fitted is output by a detection element located at the edge where the door / window frame and the door / window sash are fitted. The detection element can be a contact detection element, a displacement detection element, or a magnetic detection element. When the door / window sash and the door / window frame reach the fitted state at the location of the circumferential sealing component, the fitting signal is output.

[0030] To facilitate a unified determination of the locking state, the following relationship can be used: in, Indicates the result of the locking status determination; This indicates that the interlocking component is in position. This indicates that the door / window sash and frame are properly aligned. The output is from the detection element on the locking assembly, the The outputs are from the detector at the edge of the sector frame, and both are received by the controller and used in the logical judgment.

[0031] when When established, it indicates that the locking action has been completed and the sector frame is properly engaged, allowing the controller to proceed with the subsequent detection branch connection and pressure maintenance detection process; when If the condition is not met, the controller will not initiate subsequent detection and compensation actions, and will keep the micro-ventilation bypass component in the closed control state, while keeping the top pressure components of each auxiliary pressing component in the retracted position.

[0032] The completion of locking and fitting are considered as prerequisites for testing, in order to avoid situations where the doors and windows only complete mechanical locking but the sash and frame are not fully fitted, or where the sash and frame are only partially fitted but the locking is not in place, thus requiring a partial compensation process.

[0033] After the controller determines that the interlocking state is established, it first sends a closing command to the micro-ventilation bypass component, causing the opening and closing element to move to the closed position and block the flow path of the bypass duct. The opening and closing element can adopt a sliding plate structure, a rotating baffle structure, or a flip valve plate structure. In this embodiment, a sliding plate structure is adopted. When the sliding plate moves along the length of the bypass duct to the blocking position, the bypass duct is closed.

[0034] Subsequently, the controller sends a retraction command to each auxiliary clamping component, causing each pressing member to be in the retracted position. When in the retracted position, the pressing member maintains a gap with the back of the corresponding sealing strip, or maintains a contact state that does not form a compensating clamping amount, to avoid additional resistance during the opening and closing of doors and windows. The retraction of the pressing member can be achieved by the reverse drive of the driving component or by the push of the reset component. In this embodiment, the driving component uses a miniature lead screw motor, and the reset component uses a compression spring. The pressing member returns to the retracted position under the reverse action of the lead screw motor and the reset action of the compression spring.

[0035] In step S2, the circumferential detection air chamber is formed by the first sealing strip, the second sealing strip, and the inner wall of the door and window frame profile and the outer wall of the door and window sash profile that cooperate with them. The first sealing strip and the second sealing strip are continuously arranged along the circumferential direction of the cooperation between the door and window frame and the door and window sash, and a closed air chamber is formed after the door and window sash is locked.

[0036] To enable separate detection of the sealing status at different circumferential locations, partitions are provided at the junctions of the upper frame and the hinge side, the upper frame and the locking side, the lower frame and the hinge side, and the lower frame and the locking side. These partitions can be partition blocks, sealing components, or closed-end structures that mate with the ends of the sealing strips. The partitions mate with the first sealing strip, the second sealing strip, and the corresponding profile wall surfaces, dividing the circumferential detection air chamber into multiple separate detection sections.

[0037] Each testing section is connected to the testing branch via an independent branch channel. These independent branch channels are located inside the door and window frame profiles, with one independent branch channel corresponding to each testing section. A branch switching unit is located between the testing branch and each independent branch channel; in this embodiment, a multi-channel solenoid valve assembly is used.

[0038] The pressure supply unit uses a miniature air pump, and the pressure detection unit uses a pressure sensor; both are located on the detection branch. The controller controls the branch switching unit to connect different detection sections one by one, causing the pressure supply unit to input detection pressure to the current detection section and the pressure detection unit to collect the pressure value of that detection section.

[0039] The detection sequence can be performed sequentially as follows: upper frame detection section, lower frame detection section, hinge side detection section, and locking side detection section; or it can be performed sequentially according to the controller's preset sequence. Regardless of the sequence used, the controller ensures that only one detection branch corresponding to a detection section is activated at a time to avoid crosstalk between different detection sections.

[0040] During each test, the controller first activates the detection branch corresponding to a detection section. The miniature air pump pressurizes that detection section until the set detection pressure is reached, at which point pressurization stops and the system enters a pressure stabilization phase. The pressure stabilization phase is used to eliminate pressure fluctuations at the moment of pressure termination, ensuring that the initial pressure value collected by the pressure detection unit and the subsequent holding pressure value are in a relatively stable state.

[0041] After pressure stabilization, the controller starts timing and enters the holding phase. The holding time and sampling period are set by the controller according to preset control rules, which can be pre-determined and written into the controller based on the detection branch volume, the output stability of the pressure supply unit, and the debugging results of the door and window prototype. The pressure sensor collects the initial pressure value at the start of the holding phase, collects pressure change data according to the set sampling period during the holding phase, and collects the final pressure value at the end of the holding time. Then, the controller switches the branch switching unit to complete the pressure holding detection of the remaining detection sections in sequence.

[0042] To better reflect the pressure changes during the holding phase, the following relationship can be used: in, Indicates the first The detection section in the first Sampling time and the first Pressure change between sampling times; and These represent the pressure values ​​of the detection section at two adjacent sampling times. All pressure values ​​are collected by the pressure detection unit when the current detection branch is connected and recorded by the controller in the sampling sequence. The controller uses this relationship to obtain the pressure change between adjacent sampling times during the holding phase and records the pressure change process of each detection section accordingly.

[0043] After obtaining the pressure values ​​at each sampling point during the holding phase, the following relationship can be further used to facilitate the calculation of the total pressure change during the holding phase: in, Indicates the first The total pressure change of each detection section during the holding phase; Indicates the first The number of samplings per detection segment during the holding phase; Indicates the first The initial pressure value of each detection section when the pressure stabilization ends and begins to be maintained; Indicates the first The end pressure value of each detection segment at the end of the holding time. The controller determines the sampling period and hold time. and The pressure is collected by the pressure detection unit. The controller determines the total pressure change during the holding phase based on this relationship and correlates it with the initial and final pressure values.

[0044] To facilitate the conversion of pressure changes in different detection sections within their respective holding times into comparable parameters, the following relationship can be used: in, Indicates the first Pressure attenuation parameters for each detection section; Indicates the first The initial pressure value of each detection section at the end of pressurization; Indicates the first The end pressure value of each detection segment at the end of the holding time; Indicates the first The holding time of each detection segment; subscript This indicates the detection section number. All the above parameters are collected or recorded by the pressure detection unit and controller during the detection process. The controller calculates the pressure attenuation parameters for each detection section based on this formula, which serves as the basis for leak determination and compensation level classification.

[0045] In step S3, the controller pre-stores the leakage detection threshold. And the boundary values ​​of the pressure attenuation parameter ranges corresponding to Level 1, Level 2, and Level 3 compensation. , and satisfy The controller compares the pressure decay parameters of each detection section with the leakage detection threshold to determine whether it belongs to the target leakage section.

[0046] To facilitate the determination of the target leakage section, the following relationship can be used: in, Indicates the first Whether each detection zone is identified as a target leak zone; Indicates the first Pressure attenuation parameters for each detection section; This indicates the threshold for determining a leak. When... When the pressure decay parameter of the detection section is higher than the leakage judgment threshold, it indicates that the subsequent compensation process needs to be initiated; when When the condition is met, it indicates that the sealing status of the detection section meets the requirements, and the compensation process is not initiated. The controller determines whether each detection section belongs to the target leakage section based on this relationship.

[0047] The controller continues to determine the compensation level for the target leak section. To facilitate mapping different leak levels to different compensation levels, the following relationship can be used: in, Indicates the first The compensation level corresponding to each target leakage section; Indicates the first Pressure attenuation parameters for each detection section; Indicates the threshold for leak detection; This represents the boundary value between the first-level compensation and the second-level compensation. This represents the boundary value between the secondary and tertiary compensation levels. As obtained from step S2, the , and The formula is pre-stored by the controller. The controller determines the compensation level corresponding to each target leakage section based on this formula, and controls the corresponding auxiliary clamping components to enter the corresponding compensation position accordingly.

[0048] When multiple target leakage sections exist, the controller determines the compensation order based on the pressure attenuation parameters of each target leakage section, from largest to smallest. To facilitate a unified sorting basis, the following relationship can be used: And in accordance with The order of compensation is determined by the sequence of events. Indicates the first Compensation priority indicators for each detection segment; This indicates whether the detection section is the target leak section; This indicates the pressure attenuation parameter of the detection section; Indicates the number of target leakage sections; to This indicates the results sorted by priority from highest to lowest. Due to the non-target leakage section... The value is 0, therefore it is not included in the compensation sorting; the target leakage section It is consistent with its pressure decay parameters. The controller sequentially calls the corresponding auxiliary clamping components to perform compensation and retesting according to the above sorting results, thereby prioritizing the detection sections with more obvious leakage.

[0049] In step S4, each auxiliary clamping component is set up in a one-to-one correspondence with each detection section. The upper frame detection section corresponds to the upper frame auxiliary clamping component, the lower frame detection section corresponds to the lower frame auxiliary clamping component, the hinge side detection section corresponds to the hinge side auxiliary clamping component, and the locking side detection section corresponds to the locking side auxiliary clamping component.

[0050] Each auxiliary clamping component is located inside the door / window frame or door / window sash in the corresponding detection section, and the top clamping component is located on the back side of the corresponding sealing strip. In this embodiment, the top clamping component is located on the back side of the first sealing strip. When the top clamping component moves forward, it pushes the first sealing strip to the side of the door / window sash to undergo elastic deformation, thereby increasing the local clamping amount in the corresponding detection section.

[0051] Each auxiliary clamping component includes a pressing element, a driving element, and a resetting element. The pressing element uses a strip-shaped pressing block, the driving element uses a miniature lead screw motor, and the resetting element uses a compression spring. The pressing element can switch between a retracted position, a first-level compensation position, a second-level compensation position, and a third-level compensation position. The first-level compensation position corresponds to the first preset stroke, the second-level compensation position corresponds to the second preset stroke, and the third-level compensation position corresponds to the third preset stroke, with the third preset stroke being greater than the second preset stroke, and the second preset stroke being greater than the first preset stroke. Each compensation position can be preset according to the debugging results of the door and window prototype, the compression deformation of the sealing strip, and the pre-stored rules of the controller.

[0052] To facilitate mapping the compensation level to the target position of the top-pressure component, the following relationship can be used: and satisfy in, Indicates the first Each target leakage section corresponds to the target location of the top pressure component; This indicates the compensation level corresponding to the detection section; , and These represent the primary compensation location, the secondary compensation location, and the tertiary compensation location, respectively. Indicates the retraction position. The controller determines this based on step S3. , , The executable stroke of the auxiliary clamping component is predetermined accordingly.

[0053] This formula establishes a one-to-one correspondence between compensation levels and compensation positions. The controller only drives the auxiliary clamping components corresponding to the target leakage section, causing the corresponding top pressure component to move from the retracted position to the corresponding compensation position. Detection sections not identified as target leakage sections remain unchanged. The controller applies different compensation positions to different detection sections to implement local compensation based on the detection results of each zone.

[0054] In step S5, after local compensation is completed, the controller performs pressure holding detection again on the compensated target leakage section to obtain the retest pressure attenuation parameters after compensation. The retest method is the same as the pressure holding detection method in step S2. The branch switching unit connects the detection branch of the compensated detection section, and the pressure supply unit inputs the detection pressure to the detection section. After the set detection pressure is reached, the pressurization stops and the pressure stabilization stage begins. After the pressure stabilization is completed, the pressure detection unit collects the initial retest pressure value, the end retest pressure value, and the retest holding time. The controller calculates the retest pressure attenuation parameters according to the same rules as the initial detection.

[0055] When multiple target leakage sections exist, the controller performs local compensation and local retesting sequentially according to the compensation order. After each target leakage section meets the leakage judgment requirements, the controller can also sequentially connect all detection sections to perform circumferential retesting to verify the overall sealing status after local compensation.

[0056] To ensure that the same evaluation criteria are used for both the retest and the initial test, the following relationship can be adopted: in, Indicates the first The pressure attenuation parameters of each detection section after local compensation were re-measured. This indicates the initial pressure value when the test section is retested; This indicates the final pressure value when the test section is retested; This indicates the holding time during retesting of the detection section. , The pressure data is collected by the pressure detection unit during the retesting process. The timing data is obtained from the controller. This formula is used to allow the retest results after partial compensation to be directly compared with the original leakage judgment threshold, thereby clarifying whether the current compensation position has achieved the expected sealing effect.

[0057] In step S6, when the retested pressure attenuation parameter of a certain target leakage section at the current compensation position is not higher than the leakage judgment threshold, the controller keeps the top pressure component of the corresponding auxiliary clamping component at the current compensation position.

[0058] In the implementation method using a miniature lead screw motor as the driving component, the pressing component can be stopped at the current compensation position by means of the lead screw self-locking; in the implementation method using a non-self-locking driving component, the pressing component can be stopped at the current compensation position by maintaining the current position of the driving component or by setting a mechanical stop.

[0059] If the retested pressure attenuation parameter of a target leakage section at the current compensation position is still higher than the leakage judgment threshold, the controller controls the top pressure component of the detection section to move from the current compensation position to the next compensation position, and re-executes the retesting process of step S5. If the current position is at the first-level compensation position and the standard is not met, it moves to the second-level compensation position; If the current compensation level is at level 2 and has not met the standard, then proceed to level 3 compensation. If the pressure attenuation parameter is still higher than the leakage judgment threshold after reaching the highest compensation level, then stop increasing the compensation amount.

[0060] To facilitate a unified judgment on whether the retest meets the standards, the following formula can be used: in, Indicates the first The retesting results of the target leakage section at the current compensation location; This indicates the pressure attenuation parameter for the retested section; This indicates the threshold for determining a leak. When... When this occurs, it indicates that the detection section has met the leakage judgment requirements at the current compensation position, and the controller keeps the top pressure component of the corresponding auxiliary clamping assembly in the current compensation position; when When this condition is met, it indicates that the leakage detection requirements have not yet been met at the current compensation position. The controller will either continue to execute control at the next compensation position or enter the abnormal handling branch after the highest compensation position. The controller determines whether to maintain the current compensation position or enter the next compensation position based on this relationship, and executes subsequent retest control accordingly.

[0061] After completing local retesting in multiple target leakage sections, the following formula can be used to facilitate comprehensive verification of the overall circumferential sealing condition: in, This represents the maximum value among all pressure attenuation parameters measured in the entire testing section. to These represent the retest pressure attenuation parameters for all test sections; This represents the total number of test sections. The pressure attenuation parameter for each retest is obtained by sequentially connecting the test branches of all test sections to the controller. This formula is used to aggregate the circumferential retest results into a comprehensive judgment value. As long as the maximum retest pressure attenuation parameter is not higher than the leakage judgment threshold, it can be considered that all test sections meet the sealing requirements, thus providing a unified prerequisite for subsequent micro-ventilation switching.

[0062] In step S7, the micro-ventilation bypass component is installed inside the upper or side frame of the door / window frame. The bypass duct is separated from the circumferential detection air chamber by an isolation wall, and the opening / closing element is installed on the ventilation path of the bypass duct. The opening / closing element has three switchable positions: closed, micro-ventilation, and limited opening. The closed position corresponds to the bypass duct being completely blocked, the micro-ventilation position corresponds to the bypass duct forming a normal micro-ventilation flow cross-section, and the limited opening position corresponds to the bypass duct forming a flow cross-section smaller than that of the micro-ventilation position.

[0063] To facilitate determining whether switching to a micro-ventilation position is permissible, the following decision relationship can be used: in, This represents the maximum value among all pressure attenuation parameters measured in the entire testing section. This indicates the leakage detection threshold. When the above relationship holds true, it means that the retest results of all detection sections meet the leakage detection requirements. The controller then switches the opening and closing parts from the closed position to the micro-ventilation position, causing the bypass duct to enter a micro-ventilation state. The controller executes the micro-ventilation switch after all detection sections have passed the retest to prevent entering a micro-ventilation state if local sealing deficiencies have not been eliminated.

[0064] When any target leakage section reaches its highest compensation position, and its re-measured pressure attenuation parameter still exceeds the leakage detection threshold, the controller outputs an abnormal maintenance signal. To facilitate the triggering and determination of the abnormal maintenance signal, the following formula can be used: in, This indicates the result of abnormal maintenance triggering; Indicates the first The current location of the top pressure component in the target leakage section; Indicates the position with the highest compensation. Indicates the first Re-measured pressure attenuation parameters of each target leakage section; This indicates the threshold for determining a leak. When... When established, it indicates that at least one target leakage section has reached the highest compensation position but has not yet met the leakage judgment requirements, and the controller outputs an abnormal maintenance signal.

[0065] The abnormal maintenance signal can be displayed as a text prompt, an audible and visual alarm, or a maintenance code output. The controller simultaneously keeps the opening and closing components in the closed position or switches them to a limit opening position to restrict ventilation under abnormal conditions. Based on this relationship, the controller distinguishes between the continued compensation state and the abnormal maintenance state, and outputs the abnormal maintenance signal accordingly.

[0066] In this embodiment, the locking state signal consists of a locking component in place signal and a door / window sash and door / window frame in place signal; when both the locking component in place signal and the in place signal are present, it is determined that the door / window sash and door / window frame have reached the locking state.

[0067] Furthermore, the locking component's position signal is output by a detection element located at the handle drive termination position, the locking point linkage termination position, or the lock tongue and lock seat engagement position. The fitting completion signal is output by a detection element located at the fitting edge between the door / window frame and the door / window sash. The controller performs logical judgment on both types of signals, and only when both types of signals are true simultaneously will it perform the detection branch connection and pressure maintenance detection. The two types of signals respectively reflect whether the locking action is completed and whether the sash / frame fitting is completed. The signal sources are independent of each other, but the control logic cooperates with each other.

[0068] In this embodiment, the detection sections include an upper frame detection section, a lower frame detection section, a hinge side detection section, and a locking side detection section.

[0069] Furthermore, the upper frame detection section is located at the circumferential detection air chamber position corresponding to the upper horizontal edge of the door / window frame, the lower frame detection section is located at the circumferential detection air chamber position corresponding to the lower horizontal edge of the door / window frame, the hinge side detection section is located at the circumferential detection air chamber position corresponding to the hinge side edge, and the locking side detection section is located at the circumferential detection air chamber position corresponding to the locking side edge. The four detection sections are separated from each other by partitions and each is connected to its own independent branch channel. The controller connects the detection branches corresponding to each detection section one by one according to a preset sequence, and after completing the pressurization, pressure stabilization, sampling maintenance, and termination judgment of the current detection section, it switches to the next detection section to ensure that the detection processes of different detection sections are independent of each other.

[0070] In this embodiment, each detection section sequentially connects to the corresponding detection branch through the branch switching unit to perform pressure holding detection; the pressure attenuation parameter is determined based on the initial pressure value, the pressure change value during the holding stage, and the final pressure value of each detection section.

[0071] Furthermore, the branch switching unit employs a multi-channel solenoid valve assembly, with each independent branch channel corresponding to a detection section connected to different branch interfaces of the solenoid valve assembly. The controller controls the solenoid valve assembly to sequentially connect different branch interfaces, enabling the corresponding detection section to connect with the pressure supply unit and the pressure detection unit. The initial pressure value is the pressure value after the detection section reaches the set detection pressure and completes pressure stabilization. The pressure change value during the holding period is the cumulative result of the pressure change at each sampling moment within the holding time. The final pressure value is the pressure value at the end of the holding time. The controller calculates the pressure decay parameter based on the above three quantities and uses it as the basis data for leakage judgment and compensation level classification.

[0072] In this embodiment, when there are multiple target leakage sections, the compensation order is determined according to the pressure attenuation parameter from large to small.

[0073] Furthermore, after obtaining the pressure attenuation parameters of all target leakage sections, the controller sorts the pressure attenuation parameters of each target leakage section, placing the detection sections with larger values ​​first and the detection sections with smaller values ​​later. Subsequently, the controller calls the corresponding auxiliary clamping components to perform local compensation and retesting according to this sorting result. Accordingly, detection sections with larger leakage degrees are given priority to enter the compensation process.

[0074] In this embodiment, the insufficient sealing levels include Level 1 compensation, Level 2 compensation, and Level 3 compensation. Level 1 compensation, Level 2 compensation, and Level 3 compensation correspond to different compensation positions, and the compensation positions corresponding to Level 1 compensation, Level 2 compensation, and Level 3 compensation are arranged in ascending order of compensation amount. Each auxiliary pressing component keeps the top pressing component in the retracted position when the door and window are in the open state or not in the locked state.

[0075] Furthermore, the first-level compensation position corresponds to the first preset stroke, the second-level compensation position corresponds to the second preset stroke, and the third-level compensation position corresponds to the third preset stroke, with the third preset stroke being greater than the second preset stroke, and the second preset stroke being greater than the first preset stroke. The controller controls the pressing components to enter the compensation position corresponding to the compensation level of the target leakage section. When doors and windows are open or not locked, the controller does not allow any auxiliary pressing components to enter the compensation position, and all pressing components remain in the retracted position. Through the above settings, local compensation is only performed after the doors and windows are locked and the zone detection is completed, to avoid interference during opening and closing.

[0076] Example 2 like Figure 2 and Figure 3 As shown, this is a system embodiment corresponding to the intelligent sealing and energy-saving control method described in Embodiment 1. This embodiment provides an intelligent sealing and energy-saving control system for a 70-type thermally broken aluminum alloy door and window, including a door and window frame, door and window sash, locking assembly, circumferential sealing assembly, pressure supply unit, pressure detection unit, branch switching unit, multiple auxiliary pressing assemblies, micro-ventilation bypass assembly and controller. The circumferential sealing assembly is disposed in the circumferential direction of the door and window frame and the door and window sash. The circumferential sealing assembly includes a first sealing strip and a second sealing strip. The first sealing strip and the second sealing strip form a circumferential detection air chamber after the door and window sash is locked. The circumferential detection air chamber is divided into multiple detection sections along the circumference of the door and window by multiple partitions. Each detection section is connected to the detection branch through an independent branch channel. The branch switching unit, pressure supply unit and pressure detection unit are set on the detection branch. Multiple auxiliary clamping components are provided in a one-to-one correspondence with multiple detection sections. Each auxiliary clamping component is located inside the door or window frame or inside the door or window sash of the corresponding detection section. Each auxiliary clamping component includes a pressing member located on the back side of the corresponding sealing strip. The pressing member can switch between a retracted position and multiple compensation positions. The micro-ventilation bypass component is installed inside the upper frame or side frame of the door and window frame. The micro-ventilation bypass component includes a bypass air duct, an opening and closing device installed on the bypass air duct, and an isolation wall installed between the bypass air duct and the circumferential detection air chamber. The controller is connected to the interlocking assembly, branch switching unit, pressure supply unit, pressure detection unit, each auxiliary pressing assembly, and micro-ventilation bypass assembly.

[0077] Furthermore, both the door and window frames and sashes are made of 70-type thermally broken aluminum alloy profiles. The first sealing strip is installed in the sealing groove of the door and window frame, and the second sealing strip is installed in the sealing groove of the door and window sash. When the door and window sash are in the locked state, the first sealing strip, the second sealing strip, the inner wall of the door and window frame profile, and the outer wall of the door and window sash profile together form a circumferential detection air chamber. The dividing part is located at the corner of the door and window frame or at the junction of each detection section, used to divide the circumferential detection air chamber into multiple mutually separated detection sections. Each detection section is connected to a detection branch through a corresponding independent branch channel, which is located inside the door and window frame profile.

[0078] The branch switching unit is located between the detection branch and each independent branch channel, and preferably adopts a multi-channel solenoid valve group structure; the pressure supply unit is located in the inner cavity of the door / window frame or in the installation cavity adjacent to the door / window frame, and preferably adopts a miniature air pump; the pressure detection unit is located at the common detection section of the detection branch, and preferably adopts a pressure sensor. The controller controls the branch switching unit to connect different detection sections one by one, so that the pressure supply unit and the pressure detection unit are connected to the corresponding detection sections, thereby performing pressure maintenance detection on each detection section.

[0079] In this embodiment, the detection sections include an upper frame detection section, a lower frame detection section, a hinge side detection section, and a locking side detection section, with adjacent detection sections separated by the partition.

[0080] Furthermore, the upper frame detection section is located at the circumferential detection air chamber position corresponding to the upper horizontal edge of the door / window frame, the lower frame detection section is located at the circumferential detection air chamber position corresponding to the lower horizontal edge of the door / window frame, the hinge side detection section is located at the circumferential detection air chamber position corresponding to the hinge side edge, and the locking side detection section is located at the circumferential detection air chamber position corresponding to the locking side edge. Adjacent detection sections are separated by a partition to form a sealed boundary. The partition can be a sealing element, a partition block, or a sealing end structure. The partition cooperates with the first sealing strip, the second sealing strip, and the inner wall of the profile to prevent direct communication between adjacent detection sections. Through this arrangement, each detection section can remain relatively independent during pressure holding detection, allowing the controller to determine the sealing status of the corresponding circumferential position based on the detection results of different detection sections.

[0081] In this embodiment, each auxiliary pressing component includes a pressing member, a driving member, and a resetting member. The driving member is connected to the pressing member in a transmission manner, and the resetting member is connected to the pressing member. The pressing member can switch between a retracted position and multiple compensation positions corresponding to different compensation levels.

[0082] Furthermore, multiple auxiliary clamping components are correspondingly set to multiple detection sections, with each auxiliary clamping component located inside the door / window frame or door / window sash of the corresponding detection section. The pressure-adjusting component is located on the back side of the corresponding sealing strip, the driving component is located inside the profile, and the reset component is located in the retraction direction of the pressure-adjusting component. The pressure-adjusting component is a strip-shaped piece extending along the length of the detection section. The driving component is preferably a miniature lead screw motor, and the reset component is preferably a compression spring. The output end of the lead screw motor is connected to the pressure-adjusting component via a nut seat. When the motor rotates forward, it pushes the pressure-adjusting component towards the back side of the corresponding sealing strip; when the motor rotates in reverse, the pressure-adjusting component moves in the retraction direction. Multiple compensation positions correspond to different compensation levels, with the first-level compensation position corresponding to the first set stroke, the second-level compensation position corresponding to the second set stroke, and the third-level compensation position corresponding to the third set stroke. After the driving component releases its forward-pushing state, the reset component pushes the pressure-adjusting component back to the retracted position.

[0083] With this structure, the controller can drive the corresponding auxiliary clamping component to perform local compensation on the corresponding sealing strip according to the degree of sealing insufficiency in different detection sections, while the top pressure component remains in the retracted position for detection sections that are not identified as target leakage sections.

[0084] In this embodiment, the opening and closing element can switch between a closed position, a micro-ventilation position, and a limited opening position.

[0085] Furthermore, the micro-ventilation bypass component is installed within the upper or side frame of the door / window frame. The bypass duct forms an independent ventilation channel within the door / window frame profile. The opening and closing mechanism is positioned along the ventilation path of the bypass duct, and an isolation wall is installed between the bypass duct and the circumferential detection air chamber. The isolation wall separates the bypass duct from the circumferential detection air chamber, preventing airflow from the bypass duct from entering the circumferential detection air chamber, thus structurally separating the sealing detection path from the micro-ventilation path.

[0086] The opening and closing mechanism preferably adopts a sliding plate structure, with the sliding plate reciprocating along the length of the bypass duct. The closed position corresponds to the sliding plate completely blocking the bypass duct's inlet; the micro-ventilation position corresponds to the sliding plate partially opening the bypass duct, creating the necessary flow cross-section for micro-ventilation; and the limited opening position corresponds to the sliding plate only opening a portion of the bypass duct, creating a flow cross-section smaller than that of the micro-ventilation position. To ensure stable switching between the three positions, limit slots or positioning holes corresponding to the three positions can be provided on the sliding plate's travel. The drive mechanism, under the control of the controller, moves the sliding plate to the corresponding position and holds it there.

[0087] In this embodiment, the controller is connected to the interlocking component, the branch switching unit, the pressure supply unit, the pressure detection unit, each auxiliary clamping component, and the micro-ventilation bypass component. The interlocking component provides an interlocking status signal to the controller. The branch switching unit switches the detection branches corresponding to different detection sections under the control of the controller. The pressure supply unit inputs the detection pressure to the currently connected detection section. The pressure detection unit collects the pressure data of the corresponding detection section. Each auxiliary clamping component performs local clamping compensation on the corresponding detection section according to the compensation command output by the controller. The micro-ventilation bypass component establishes a micro-ventilation path when the retest meets the requirements and maintains the closed position or switches to the limit opening position in abnormal conditions. The controller calculates the pressure attenuation parameters, determines leakage, determines the compensation level, and determines the retest results for each detection section, corresponding to the control logic in Embodiment 1.

[0088] The system operation process in this embodiment is as follows: When the locking component outputs a locking component in position signal and the detection component at the edge of the door / window frame and the door / window sash outputs a fitting in position signal, the controller first controls the opening and closing components of the micro-ventilation bypass component to be in the closed position, and controls the top pressure components of each auxiliary pressing component to remain retracted; then, the controller controls the branch switching unit to sequentially connect the detection branches corresponding to each detection section, the pressure supply unit inputs the detection pressure to the current detection section, and the pressure detection unit collects the corresponding pressure data; the controller determines whether there is a target leakage section and the corresponding compensation level based on the detection results of each detection section, and drives the corresponding auxiliary pressing component to perform local compensation; After partial compensation is completed, the controller performs a retest on the compensated detection section or all detection sections to confirm the sealing status after compensation. When the retest of all detection sections meets the requirements, the controller controls the opening and closing parts to switch to the micro-ventilation position, so that the system enters the controlled micro-ventilation state. When any target leakage section reaches the highest compensation position and the retest still does not meet the requirements, the controller outputs an abnormal maintenance signal and controls the opening and closing parts to remain in the closed position or switch to the limit opening position to limit the ventilation volume under abnormal conditions.

[0089] Through the above-mentioned structural coordination and action chain settings, this embodiment forms a continuous control process of lockout confirmation, zone detection, compensation judgment, auxiliary clamping, retest confirmation, micro-ventilation switching, and abnormal maintenance.

[0090] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
