Description

Technical Field

[0001] The embodiments of the present invention relate to the fields of building curtain walls, energy-saving glass and gas sealing monitoring technology, and particularly to a curtain wall monitoring and repair system and monitoring and repair method. Background Technology

[0002] Multi-cavity glass curtain walls significantly improve thermal insulation performance by creating multiple independent chambers between adjacent glass panels and filling them with inert gas. However, existing projects typically only conduct a single airtightness check at the factory or during installation, lacking long-term monitoring during operation. Because ambient temperature fluctuations cause changes in internal pressure, a single pressure measurement is insufficient to distinguish between normal thermal response and chronic leakage; furthermore, complex conditions often exist between multiple chambers, such as asynchronous leakage levels and edge sealing aging. Once insulation performance deteriorates, current technology cannot accurately locate the specific leaking chamber, often requiring panel removal or complete replacement, resulting in high maintenance costs and difficult construction.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Figure 1 This is a schematic diagram of a curtain wall monitoring and repair system provided in an embodiment of the present invention. Figure 2 A schematic diagram of a curtain wall structure provided in an embodiment of the present invention is shown below. Figure 1 and Figure 2 The curtain wall monitoring and repair system includes: a multi-cavity curtain wall 110, an air supply module 120, a sensing module 130, a concentration detection module 140, and a control module 150.

[0018] The multi-cavity curtain wall 110 includes multiple curtain wall units 111, each curtain wall unit 111 including multiple independent gas chambers 112, each gas chamber 112 including an air inlet and a sampling port.

[0019] The gas replenishment module 120 is connected to the gas inlet, and the concentration detection module 140 is connected to the sampling port. The gas replenishment module 120 is used to replenish gas, and the concentration detection module 140 is used to detect the real-time gas concentration at the sampling port.

[0020] The sensing module 130 is installed in each gas chamber 112. The sensing module 130 is used to detect real-time environmental parameters in each gas chamber 112.

[0021] The control module 150 is connected to the gas replenishment module 120, the sensing module 130, and the concentration detection module 140, respectively. The control module 150 is used to locate the target gas chamber where a leak has occurred based on real-time environmental parameters, and to control the gas replenishment module 120 to replenish gas to the target gas chamber. The control module 150 is also used to control the gas replenishment module 120 to stop replenishing gas based on the real-time gas concentration.

[0022] Specifically, the multi-cavity curtain wall 110 is a building envelope structure composed of multiple curtain wall units 111 assembled and spliced ​​together by a fixed structure. Each curtain wall unit 111 is internally divided into multiple independent gas chambers 112, which are physically isolated from each other and their gases are not directly connected. For example, when the curtain wall unit 111 includes an inner glass 1111, a layer of intermediate glass 1112, and an outer glass 1113, two independent gas chambers 112 are formed. When it includes two layers of intermediate glass 1112, three independent gas chambers 112 are formed, and so on. This embodiment of the invention does not impose a specific limit on the number of gas chambers 112; those skilled in the art can flexibly set them according to building energy-saving requirements, sound insulation requirements, and heat insulation requirements.

[0023] Each gas chamber 112 is equipped with an air inlet and a sampling port. Optionally, the air inlet and sampling port can be located on one side of the inner glass 1111, that is, the side facing the interior, to facilitate later maintenance operations and avoid the safety risks of high-altitude outdoor operations.

[0024] Multiple curtain wall units 111 are connected by a fixed structure to form a complete multi-cavity curtain wall 110. The multi-cavity curtain wall 110 also includes unit frames, which are connected to the curtain wall mullions 250 and beams 260 via pressure blocks 210, bases 220, bolt groups 230, pins 240, and screws 280. Boundary seals 270 are disposed between the glass panels of the curtain wall units 111 and the unit frames. The sealing strips 271 can prevent dust and rainwater from entering the interior, while providing an outer layer of sealing protection for the gas chambers 112.

[0025] The gas replenishment module 120 is connected to the air inlet of each gas chamber 112, and the gas replenishment module 120 can replenish inert gas into the gas chamber 112. The concentration detection module 140 can detect the real-time gas concentration in the gas chamber 112 and at the sampling port.

[0026] Sensing modules 130 are installed inside each gas chamber 112 and can detect real-time environmental parameters within the chamber. Sensing modules 130 include, but are not limited to, pressure sensors and temperature sensors, used to detect real-time pressure and temperature parameters within the chamber, respectively. Data from each sensor is transmitted to the control module 150 via wired or wireless means.

[0027] The control module 150 is communicatively connected to the gas replenishment module 120, the sensing module 130, and the concentration detection module 140, respectively. The communication method can be either direct wired or wireless communication, or indirect wired or wireless communication. In this embodiment of the invention, for example, the data acquisition unit 310 is configured to receive data transmitted by the sensing module 130 and then forward it to the control module 150, thereby receiving data signals in batches.

[0028] The control module 150 receives real-time environmental parameters detected by the sensor module 130, such as real-time air pressure and real-time temperature parameters. Based on the real-time environmental parameters, it locates the target gas chamber where a leak has occurred. For example, it compares the real-time environmental parameters of gas chamber 112 with the initial environmental parameters. If the deviation is greater than a preset safety range, it indicates that gas chamber 112 has a risk of leakage, thus identifying the corresponding gas chamber 112 as the target gas chamber.

[0029] After identifying the target gas chamber, the control module 150 opens the corresponding air inlet and sampling port. The gas replenishment module 120 fills the target gas chamber with gas, while the concentration detection module 140 monitors the concentration of the discharged gas in real time through the sampling port. A displacement circulation channel is formed in the target gas chamber, where gas enters the chamber through the air inlet and discharges the low-concentration mixed gas from the chamber through the sampling port. When the real-time gas concentration detected at the sampling port reaches the preset target value, the filling is considered complete, all relevant isolation valves are closed, and gas replenishment stops.

[0030] The curtain wall monitoring and repair system provided in this embodiment of the invention uses a sensor module 130 installed in each independent gas chamber 112 to accurately locate the leaking target gas chamber based on real-time environmental parameters, avoiding the shortcomings of traditional overall detection methods that cannot distinguish the leak location. The control module 150 controls the corresponding gas replenishment module 120 in the target gas chamber to perform targeted gas replenishment and repair based on the location results, eliminating the need for manual inspection and operation, significantly improving maintenance efficiency and reducing the safety risks of high-altitude operations. Furthermore, each gas chamber 112 is independent and does not interfere with each other, allowing for independent monitoring and replenishment systems with high reliability and good maintenance flexibility.

[0031] Figure 3 This is a schematic diagram of the structure of a control module provided in an embodiment of the present invention, combined with... Figure 2 See Figure 3 The control module 150 includes an initialization unit 151, a data unit 152, and a repair unit 153.

[0032] The initial unit 151 is used to number each gas chamber 112 and obtain the initial gas concentration and initial environmental parameters.

[0033] Data unit 152 is used to classify risks based on initial gas concentration, initial environmental parameters, real-time environmental parameters and real-time gas concentration, and to locate the target gas chamber where a leak has occurred.

[0034] The repair unit 153 is used to control the gas replenishment module 120 to replenish gas to the target gas chamber.

[0035] Specifically, each gas chamber 112 in the multi-cavity curtain wall 110 is independent. Therefore, the initial unit 151 can number each gas chamber 112 in the multi-cavity curtain wall 110 during the system deployment or reset phase. The numbering can adopt a hierarchical coding method of curtain wall unit 111 number and chamber sequence number, for example, the second gas chamber 112 of the third curtain wall unit 111. Global sequence coding can also be used. Alternatively, communication address numbering can be used, for example, the actual installation position of each gas chamber 112 can be determined by mapping the communication IP address or MAC address corresponding to the sensor module 130, thereby realizing a one-to-one correspondence between the gas chamber 112 and its digital identity, laying the foundation for subsequent accurate positioning.

[0036] The initial gas concentration is the gas concentration in each gas chamber 112 of the system under steady-state conditions. The initial environmental parameters are the environmental parameters synchronously collected in each gas chamber 112 under the same steady-state conditions. The initial unit 151 acquires the initial gas concentration and initial environmental parameters of each gas chamber 112. The acquisition of the initial gas concentration and initial environmental parameters is not limited to on-site measurements during system installation. Theoretical calculations can also be used, such as those extrapolated from the inflation equipment settings and chamber volume. Factory calibration values ​​can also be used, such as those measured by the curtain wall manufacturer during factory quality inspection. Historical statistical values ​​can also be used, such as those derived from long-term monitoring data of the same batch of curtain wall units 111. These multiple acquisition methods improve the system's adaptability to different engineering scenarios.

[0037] Data unit 152 receives real-time environmental parameters detected by sensor module 130 and real-time gas concentration detected by concentration detection module 140, and correlates and matches them with the initial gas concentration and initial environmental parameters recorded by initial unit 151 to provide data input for subsequent risk classification. In this embodiment of the invention, data unit 152 can also preprocess the data, such as performing moving average filtering, Kalman filtering, etc., on the received real-time data to remove sensor noise and transient interference.

[0038] Risk classification is an assessment of the leakage risk of gas chamber 112. For example, risk classification can include low risk, medium risk, and high risk levels. For low-risk and medium-risk chambers, the system can continuously observe and record trends. For high-risk chambers, a gas replenishment and repair process needs to be triggered, thereby achieving on-demand graded maintenance and avoiding over-repair or under-repair.

[0039] For example, data unit 152 can determine the risk level by comparing and analyzing initial parameters with real-time parameters. For instance, if the deviations between initial and real-time environmental parameters, as well as the deviations between initial and real-time gas concentrations, are all within a preset safety range, it can be defined as low risk. If at least one of the deviations between initial and real-time environmental parameters, as well as the deviations between initial and real-time gas concentrations, exceeds the preset safety range, it can be defined as medium risk. If the deviations between initial and real-time environmental parameters, as well as the deviations between initial and real-time gas concentrations, all exceed the preset safety range, it can be defined as high risk. The gas chamber 112 determined to be high risk is identified as the target gas chamber, and its corresponding number and risk level are output to repair unit 153. It should be noted that, in this embodiment of the invention, risk classification is performed by comparative analysis. In other embodiments, data unit 152 can predict future deterioration trends based on the slope of changes in gas pressure or concentration through time series analysis. Leakage probability prediction is performed based on multi-dimensional features such as gas pressure, temperature, and concentration using models such as support vector machines, random forests, and LSTM neural networks. Alternatively, air pressure deviation and concentration deviation can be mapped to fuzzy sets, and data analysis can be performed through comprehensive risk assessment using a fuzzy rule base, without specific restrictions here.

[0040] After receiving the target gas chamber information output by the data unit 152, the repair unit 153 controls the opening of the corresponding air inlet and sampling port of the target gas chamber. The gas replenishment module 120 fills the target gas chamber with inert gas, while the concentration detection module 140 detects the concentration of the discharged gas in real time from the sampling port. A displacement circulation channel is formed in the target gas chamber, that is, inert gas enters the chamber from the air inlet and discharges the low-concentration mixed gas in the chamber from the sampling port. When the real-time gas concentration detected at the sampling port reaches the preset target value, the filling is determined to be complete, all relevant isolation valves are closed, and gas replenishment is stopped.

[0041] It should be noted that the process of the repair unit 153 controlling the gas replenishment module 120 to replenish gas is not limited to a single replenishment until the target is met. In other embodiments, segmented gas replenishment can be used, for example, first filling in a small amount of gas for a pressure test, and then filling it completely after confirming that there is no major leakage, to avoid ineffective inflation of severely damaged chambers.

[0042] Combination Figure 1 and Figure 2The sensing module 130 includes a pressure sensor 131 and a temperature sensor 132. The pressure sensor 131 and temperature sensor 132 are mounted on the glass constituting the gas chamber 112. Each gas chamber 112 corresponds to a set of pressure sensors 131 and temperature sensors 132. The sensor bodies are physically isolated from the interior of the chambers via a sealing diaphragm or sealing joint, ensuring that the original airtight structure of the chambers is not damaged while acquiring the internal state parameters. The pressure sensor 131 and temperature sensor 132 can be two independent discrete devices, or they can be a composite sensor module integrating pressure-sensitive and temperature-sensitive elements, to reduce space occupation and improve synchronous acquisition accuracy.

[0043] Optionally, real-time environmental parameters include real-time air pressure and real-time temperature parameters. Initial environmental parameters include initial air pressure and initial temperature parameters.

[0044] Data unit 152 includes a temperature compensation unit and an analysis and positioning unit.

[0045] The temperature compensation unit is used to perform temperature compensation on the real-time air pressure parameters based on the real-time temperature parameters and the initial temperature parameters, so as to obtain the compensated air pressure parameters.

[0046] The analysis and positioning unit performs risk classification of gas chamber 112 and locates the target gas chamber where leakage has occurred based on the deviation between the compensated gas pressure parameters and the initial gas pressure parameters, as well as the deviation between the real-time gas concentration and the initial gas concentration.

[0047] Specifically, based on the ideal gas law, under the premise that the volume of the sealed chamber and the amount of gaseous substance remain constant, the gas pressure is directly proportional to the absolute temperature. Therefore, the temperature compensation unit, based on the ideal gas law, can eliminate the influence of temperature fluctuations on the gas pressure reading. The compensated gas pressure parameter characterizes the pure gas pressure change caused only by gas leakage or infiltration under actual temperature conditions, eliminating the interference of ambient temperature fluctuations.

[0048] The analysis and positioning unit calculates the deviation between the compensated gas pressure parameters and the initial gas pressure parameters, as well as the deviation between the real-time gas concentration and the initial gas concentration. A first preset safety range can be set for the gas pressure deviation, and a second preset safety range can be set for the concentration deviation. The determination of each preset safety range can be based on the maximum allowable leakage rate in curtain wall design specifications and energy-saving standards. Alternatively, the interval boundaries can be derived through statistical analysis of historical monitoring data from similar curtain wall units 111. Alternatively, the performance degradation inflection point value can be determined through accelerated aging experiments.

[0049] When the deviation between the compensated gas pressure parameter and the initial gas pressure parameter is less than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is less than the second preset safety range, it can be determined as low risk.

[0050] When the deviation between the compensated air pressure parameter and the initial air pressure parameter is greater than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is less than the second preset safety range, or when the deviation between the compensated air pressure parameter and the initial air pressure parameter is less than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is greater than the second preset safety range, it can be determined as medium risk.

[0051] When the deviation between the compensated gas pressure parameter and the initial gas pressure parameter is greater than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is greater than the second preset safety range, it can be determined as a high-risk situation.

[0052] High-risk gas chamber 112 is identified as the target gas chamber, and its number and risk level are output to the repair unit 153.

[0053] It should be noted that, as an example of the embodiments of the present invention, risk classification is divided into low, medium and high risk. In other embodiments, more levels may be classified, or continuous numerical scoring may be used instead of discrete level classification. The present invention does not impose specific limitations on this.

[0054] Figure 4 A schematic diagram of another control module provided in an embodiment of the present invention is shown below. Figure 4 The control module 150 also includes a verification unit 154, which is used to maintain the pressure and verify the concentration of the repaired target gas chamber.

[0055] Specifically, after the repair unit 153 completes the gas replenishment and repair operation on the target gas chamber, the verification unit 154 performs a pressure holding test and concentration verification on the target gas chamber to verify whether the repair effect meets the preset standard. It should be noted that the verification unit 154, like the initial unit 151, data unit 152, and repair unit 153, can be a software program segment running on a processor, a functional block implemented by dedicated hardware circuitry, or a hybrid implementation combining software and hardware. This embodiment of the invention does not limit the specific implementation form of the verification unit 154.

[0056] After the gas replenishment repair is completed, all air inlets and sampling ports of the target gas chamber are closed to restore the chamber to a sealed state. Real-time gas pressure and temperature parameters within the chamber are continuously or intermittently monitored during the preset pressure holding time. To improve accuracy, the verification unit 154 also performs temperature compensation on the real-time gas pressure parameters during the pressure holding period to obtain the compensated pressure holding pressure. If the rate of decrease of the compensated pressure holding pressure during the pressure holding period exceeds a preset allowable threshold, or if the compensated pressure holding pressure at the end of the pressure holding period is lower than the preset lower limit, the pressure holding test is deemed to have failed, indicating that a leak or sealing defect still exists in the chamber, and simple gas replenishment has not fundamentally solved the problem.

[0057] Concentration verification can be performed during or after the pressure holding test by re-detecting the real-time gas concentration in the target gas chamber using the concentration detection module 140, and comparing the detection result with the initial gas concentration or the preset target concentration. If the real-time gas concentration is not lower than the preset lower limit, the concentration verification is deemed successful, confirming that the gas composition in the chamber has returned to the performance level required by the design. If the real-time gas concentration is lower than the preset lower limit, the concentration verification is deemed unsuccessful.

[0058] Furthermore, if either the pressure holding test or the concentration verification fails, the verification unit 154 generates a maintenance alarm message and outputs the target gas chamber number, the fault type of pressure holding failure or concentration non-compliance, and historical repair records to the control module 150. This prompts maintenance personnel to perform targeted repairs on the sealing structure of the target gas chamber, rather than repeatedly performing ineffective gas replenishment operations. Only when both the pressure holding test and the concentration verification pass will the verification unit 154 mark the target gas chamber as repair complete, allowing the target gas chamber to resume monitoring and circulation.

[0059] The verification unit 154 verifies the repair effect through pressure holding test and concentration verification, ensuring that each repair truly restores the sealing performance and thermal performance of the chamber, avoiding repeated inflation and energy waste caused by incomplete repair, and ensuring the reliability and energy-saving effect of the multi-cavity curtain wall in long-term operation.

[0060] Figure 5 Provided for embodiments of the present invention Figure 2 A partially enlarged structural diagram, combined with Figure 2 See Figure 5 The curtain wall unit 111 includes an inner glass panel 1111, at least one intermediate glass panel 1112, and an outer glass panel 1113, all stacked together. Adjacent glass panels are separated by spacers 410 at both ends. A gas chamber 112 is formed between adjacent glass panels.

[0061] The curtain wall unit 111 also includes a first air duct 420 and a second air duct 430.

[0062] The first gas guide line 420 includes a first end and multiple second ends. The gas replenishment module 120 is connected to the first end of the first gas guide line 420. The second ends of the first gas guide line 420 are respectively connected to the air inlets of the gas chambers 112 in the stacking direction.

[0063] The second gas delivery line 430 includes a first end and multiple second ends. The concentration detection module 140 is connected to the first end of the second gas delivery line 430. The second ends of the second gas delivery line 430 are respectively connected to the sampling ports of the gas chambers 112 in the stacking direction.

[0064] The repair unit 153 is also used to connect the first end of the first gas guide line 420 to the second end of the first gas guide line 420 corresponding to the target gas chamber before the control gas replenishment module 120 replenishes gas to the target gas chamber. It also connects the first end of the second gas guide line 430 to the second end of the second gas guide line 430 corresponding to the target gas chamber.

[0065] Specifically, taking a triple-glazed, two-cavity structure as an example, the curtain wall unit 111 includes an inner glass 1111, a first intermediate glass 1112, and an outer glass 1113 stacked sequentially, forming two independent gas chambers 112. The first gas chamber 112 is the space between the inner glass 1111 and the first intermediate glass 1112, and the second gas chamber 112 is the space between the first intermediate glass 1112 and the outer glass 1113.

[0066] Taking a four-glass, three-cavity structure as an example, the curtain wall unit 111 includes an inner glass 1111, a first intermediate glass 1112, a second intermediate glass 1112, and an outer glass 1113 stacked sequentially, forming three independent gas chambers 112. The first gas chamber 112 is the space between the inner glass 1111 and the first intermediate glass 1112; the second gas chamber 112 is the space between the first intermediate glass 1112 and the second intermediate glass 1112; and the third gas chamber 112 is the space between the second intermediate glass 1112 and the outer glass 1113.

[0067] To address the issue that the interfaces of the intermediate layer gas chambers 112 in the multi-pane, multi-cavity curtain wall 110 cannot be directly exposed, the air inlets and sampling ports of each gas chamber 112 are uniformly led out to the indoor operable area through miniature air guide pipes. This allows all chamber inspections and repairs to be completed indoors, completely avoiding the risks of outdoor high-altitude operations. The miniature air guide pipes may include a first air guide pipe 420 and a second air guide pipe 430.

[0068] The first air duct 420 and the second air duct 430 can be respectively arranged at the edge of the curtain wall unit 111, for example, close to the spacer members 410 on both sides. They extend along the spacer members 410 in the thickness direction from one end of the gas chamber 112 to the indoor side near the bottom of the floor, so that the inspection and repair of all chambers can be completed on the indoor side, completely avoiding outdoor high-altitude operations.

[0069] The first gas conduit 420 is used to deliver supplementary gas. The first gas conduit 420 includes a first end and multiple second ends. The supplementary gas module 120 is connected to the first end of the first gas conduit 420. Each of the second ends of the first gas conduit 420 is connected to the air inlet of each gas chamber 112 in the stacking direction.

[0070] The second gas delivery line 430 is used to deliver the sampling gas. The second gas delivery line 430 includes a first end and multiple second ends. The concentration detection module 140 is connected to the first end of the second gas delivery line 430. Each second end of the second gas delivery line 430 is connected to the sampling port of each gas chamber 112 in the stacking direction. The first gas delivery line 420 and the second gas delivery line 430 are physically independent and isolated from each other to prevent cross-contamination between different chambers during sampling and gas replenishment, ensuring the accuracy of detection and repair.

[0071] To ensure the reliability and safety of the pipeline system, each port of the first gas guide pipe 420 and the second gas guide pipe 430 can be equipped with an isolation valve. By controlling the opening and closing of the isolation valve, the connection between the corresponding gas chamber 112 and the gas guide pipe can be achieved. Each gas chamber 112 also has a removable sealing cap at its inlet and sampling port to ensure the airtightness of the gas chamber 112. When maintenance of the sealing structure is required, the sealing cap can be opened as a maintenance access point.

[0072] During the repair process, the first end of the first gas guide pipe 420 is connected to the second end of the first gas guide pipe 420 corresponding to the target gas chamber. Similarly, the first end of the second gas guide pipe 430 is connected to the second end of the second gas guide pipe 430 corresponding to the target gas chamber, forming a unidirectional fluid path from the gas replenishment module 120 through the inlet into the chamber, and then out through the sampling port to the concentration detection module 140. As the replacement process progresses, the concentration of inert gas in the discharged gas gradually increases. When the inert gas concentration in the discharged gas reaches the preset target value, it is determined that the gas in the chamber has been fully replaced, and the filling is complete. All isolation valves are closed, cutting off the gas replacement channel. Subsequently, a pressure holding and concentration verification process is initiated to verify the repair effect. If the verification passes, the repair process ends.

[0073] If the verification fails, it indicates a defect in the chamber's sealing structure, and simply adding gas cannot maintain the concentration. In this case, maintenance personnel can open the sealing cap at the end of the miniature gas duct on the indoor side, using it as an inspection port. Through this inspection port, they can inject sealing material into the chamber to perform local repairs on the seals without disassembling the entire curtain wall unit 111 or performing outdoor high-altitude operations.

[0074] Figure 6 This is a flowchart illustrating a curtain wall monitoring and repair method according to an embodiment of the present invention. This embodiment is applicable to curtain wall monitoring and repair situations. The method can be executed by a curtain wall monitoring and repair system, which can be implemented using hardware and / or software. (In conjunction with...) Figure 1 and Figure 2 The method specifically includes the following steps: S110, the concentration detection module 140 detects the real-time gas concentration at the sampling port.

[0075] S120 and sensor module 130 detect real-time environmental parameters in each gas chamber 112.

[0076] Specifically, the sensing module 130 is installed inside each gas chamber 112 and can detect real-time environmental parameters within the chamber. The sensing module 130 includes, but is not limited to, a pressure sensor 131 and a temperature sensor 132, which are used to detect real-time pressure parameters and real-time temperature parameters within the chamber, respectively. The data from each sensor is transmitted to the control module 150 via wired or wireless means.

[0077] S130 and control module 150 locate the target gas chamber where the leak has occurred based on real-time environmental parameters and initial gas concentration, and control gas replenishment module 120 to replenish gas to the target gas chamber. They also control gas replenishment module 120 to stop replenishing gas based on real-time gas concentration.

[0078] Specifically, the control module 150 receives real-time environmental parameters detected by the sensing module 130, such as real-time air pressure and real-time temperature parameters. Based on the real-time environmental parameters, the target gas chamber where the leak has occurred is located. For example, the real-time environmental parameters of gas chamber 112 are compared with the initial environmental parameters. If the deviation is greater than a preset safety range, it indicates that gas chamber 112 has a risk of leakage, thus identifying the corresponding gas chamber 112 as the target gas chamber.

[0079] After identifying the target gas chamber, the control module 150 opens the corresponding air inlet and sampling port. The gas replenishment module 120 fills the target gas chamber with gas, while the concentration detection module 140 monitors the concentration of the discharged gas in real time through the sampling port. A displacement circulation channel is formed in the target gas chamber, where gas enters the chamber through the air inlet and discharges the low-concentration mixed gas from the chamber through the sampling port. When the real-time gas concentration detected at the sampling port reaches the preset target value, the filling is considered complete, all relevant isolation valves are closed, and gas replenishment stops.

[0080] Optionally, the control module 150 includes an initialization unit 151, a data unit 152, and a repair unit 153. Figure 7 This is a flowchart illustrating another curtain wall monitoring and repair method provided in an embodiment of the present invention, combined with... Figure 2 and Figure 3 See Figure 7 ,include: S210, the concentration detection module 140 detects the real-time gas concentration at the sampling port.

[0081] S220 and sensor module 130 detect real-time environmental parameters in each gas chamber 112.

[0082] S230 and initial unit 151 number each gas chamber 112 and obtain the initial gas concentration and initial environmental parameters.

[0083] Specifically, each gas chamber 112 in the multi-cavity curtain wall 110 is independent. Therefore, the initial unit 151 can number each gas chamber 112 in the multi-cavity curtain wall 110 during the system deployment or reset phase. The numbering can adopt a hierarchical coding method of curtain wall unit 111 number and chamber sequence number, for example, the second gas chamber 112 of the third curtain wall unit 111. Global sequence coding can also be used. Alternatively, communication address numbering can be used, for example, the actual installation position of each gas chamber 112 can be determined by mapping the communication IP address or MAC address corresponding to the sensor module 130, thereby realizing a one-to-one correspondence between the gas chamber 112 and its digital identity, laying the foundation for subsequent accurate positioning.

[0084] The initial gas concentration is the gas concentration in each gas chamber 112 of the system under steady-state conditions. The initial environmental parameters are the environmental parameters synchronously collected in each gas chamber 112 under the same steady-state conditions. The initial unit 151 acquires the initial gas concentration and initial environmental parameters of each gas chamber 112. The acquisition of the initial gas concentration and initial environmental parameters is not limited to on-site measurements during system installation. Theoretical calculations can also be used, such as those extrapolated from the inflation equipment settings and chamber volume. Factory calibration values ​​can also be used, such as those measured by the curtain wall manufacturer during factory quality inspection. Historical statistical values ​​can also be used, such as those derived from long-term monitoring data of the same batch of curtain wall units 111. These multiple acquisition methods improve the system's adaptability to different engineering scenarios.

[0085] S240 and data unit 152 perform risk classification based on initial gas concentration, initial environmental parameters, real-time environmental parameters and real-time gas concentration, and locate the target gas chamber where the leak occurred.

[0086] Specifically, data unit 152 receives real-time environmental parameters detected by sensor module 130 and real-time gas concentration detected by concentration detection module 140, and correlates and matches them with the initial gas concentration and initial environmental parameters recorded by initial unit 151 to provide data input for subsequent risk classification. In this embodiment of the invention, data unit 152 can also preprocess the data, such as performing moving average filtering, Kalman filtering, etc., on the received real-time data to remove sensor noise and transient interference.

[0087] Risk classification is an assessment of the leakage risk of gas chamber 112. For example, risk classification can include low risk, medium risk, and high risk levels. For low-risk and medium-risk chambers, the system can continuously observe and record trends. For high-risk chambers, a gas replenishment and repair process needs to be triggered, thereby achieving on-demand graded maintenance and avoiding over-repair or under-repair.

[0088] For example, data unit 152 can determine the risk level by comparing and analyzing initial parameters with real-time parameters. For instance, if the deviations of initial environmental parameters and real-time environmental parameters, as well as the deviations of initial gas concentration and real-time gas concentration, are all within a preset safety range, it can be defined as low risk. If at least one of the deviations of initial environmental parameters and real-time environmental parameters, as well as the deviations of initial gas concentration and real-time gas concentration, exceeds the preset safety range, it can be defined as medium risk. If the deviations of initial environmental parameters and real-time environmental parameters, as well as the deviations of initial gas concentration and real-time gas concentration, all exceed the preset safety range, the gas chamber 112 is determined to be high-risk. The gas chamber 112 determined to be high-risk is identified as the target gas chamber, and the corresponding number and risk level are output to the repair unit 153. It should be noted that, in this embodiment of the invention, risk classification is performed by a comparative analysis method. In other embodiments, data unit 152 can predict future deterioration trends based on the slope of changes in gas pressure / concentration based on time series analysis. Leakage probability prediction is performed based on multi-dimensional features such as gas pressure, temperature, and concentration using models such as support vector machines, random forests, and LSTM neural networks. Alternatively, air pressure deviation and concentration deviation can be mapped to fuzzy sets, and data analysis can be performed through comprehensive risk assessment using a fuzzy rule base, without specific restrictions here.

[0089] S250, the repair unit 153 controls the gas replenishment module 120 to replenish gas to the target gas chamber.

[0090] Specifically, after receiving the target gas chamber information output by the data unit 152, the repair unit 153 controls the opening of the corresponding air inlet and sampling port of the target gas chamber. The gas replenishment module 120 fills the target gas chamber with inert gas, while the concentration detection module 140 detects the concentration of the discharged gas in real time from the sampling port. A displacement circulation channel is formed in the target gas chamber, that is, inert gas enters the chamber from the air inlet and discharges the low-concentration mixed gas in the chamber from the sampling port. When the real-time gas concentration detected at the sampling port reaches the preset target value, the filling is determined to be complete, all relevant isolation valves are closed, and gas replenishment is stopped.

[0091] It should be noted that the process of the repair unit 153 controlling the gas replenishment module 120 to replenish gas is not limited to a single replenishment until the target is met. In other embodiments, segmented gas replenishment can be used, for example, first filling in a small amount of gas for a pressure test, and then filling it completely after confirming that there is no major leakage, to avoid ineffective inflation of severely damaged chambers.

[0092] Optionally, real-time environmental parameters include real-time air pressure parameters and real-time temperature parameters. Initial environmental parameters include initial air pressure parameters and initial temperature parameters. Data unit 152 includes a temperature compensation unit and an analysis and positioning unit.

[0093] The temperature compensation unit performs temperature compensation on the real-time air pressure parameters based on the real-time temperature parameters and the initial temperature parameters to obtain the compensated air pressure parameters.

[0094] The analysis and positioning unit performs risk classification of gas chamber 112 and locates the target gas chamber where leakage has occurred based on the deviation between the compensated gas pressure parameters and the initial gas pressure parameters, as well as the deviation between the real-time gas concentration and the initial gas concentration.

[0095] Specifically, based on the ideal gas law, under the premise that the volume of the sealed chamber and the amount of gaseous substance remain constant, the gas pressure is directly proportional to the absolute temperature. Therefore, the temperature compensation unit, based on the ideal gas law, can eliminate the influence of temperature fluctuations on the gas pressure reading. The compensated gas pressure parameter characterizes the pure gas pressure change caused only by gas leakage or infiltration under actual temperature conditions, eliminating the interference of ambient temperature fluctuations.

[0096] The analysis and positioning unit calculates the deviation between the compensated gas pressure parameters and the initial gas pressure parameters, as well as the deviation between the real-time gas concentration and the initial gas concentration. A first preset safety range can be set for the gas pressure deviation, and a second preset safety range can be set for the concentration deviation. The determination of each preset safety range can be based on the maximum allowable leakage rate in curtain wall design specifications and energy-saving standards. Alternatively, the interval boundaries can be derived through statistical analysis of historical monitoring data from similar curtain wall units 111. Alternatively, the performance degradation inflection point value can be determined through accelerated aging experiments.

[0097] When the deviation between the compensated gas pressure parameter and the initial gas pressure parameter is less than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is less than the second preset safety range, it can be determined as low risk.

[0098] When the deviation between the compensated air pressure parameter and the initial air pressure parameter is greater than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is less than the second preset safety range, or when the deviation between the compensated air pressure parameter and the initial air pressure parameter is less than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is greater than the second preset safety range, it can be determined as medium risk.

[0099] When the deviation between the compensated gas pressure parameter and the initial gas pressure parameter is greater than the first preset safety range, and the deviation between the real-time gas concentration and the initial gas concentration is greater than the second preset safety range, it can be determined as a high-risk situation.

[0100] The high-risk gas chamber 112 is identified as the target gas chamber, and its number and risk level are output to the repair unit 153.

[0101] It should be noted that, as an example of the embodiments of the present invention, risk classification is divided into low, medium and high risk. In other embodiments, more levels may be classified, or continuous numerical scoring may be used instead of discrete level classification. The present invention does not impose specific limitations on this.

[0102] Optionally, the control module 150 further includes a verification unit 154. The curtain wall monitoring and repair method further includes: after the repair unit 153 completes the gas replenishment repair operation on the target gas chamber, the verification unit 154 performs a pressure holding test and concentration verification on the target gas chamber to verify whether the repair effect meets the preset standard. It should be noted that the verification unit 154, like the initial unit 151, data unit 152, and repair unit 153, can be a software program segment running on a processor, a functional block implemented by a dedicated hardware circuit, or a hybrid implementation combining software and hardware. The specific implementation form of the verification unit 154 is not limited in this embodiment of the invention.

[0103] After the gas replenishment repair is completed, all air inlets and sampling ports of the target gas chamber are closed to restore the chamber to a sealed state. Real-time gas pressure and temperature parameters within the chamber are continuously or intermittently monitored during the preset pressure holding time. To improve accuracy, the verification unit 154 also performs temperature compensation on the real-time gas pressure parameters during the pressure holding period to obtain the compensated pressure holding pressure. If the rate of decrease of the compensated pressure holding pressure during the pressure holding period exceeds a preset allowable threshold, or if the compensated pressure holding pressure at the end of the pressure holding period is lower than the preset lower limit, the pressure holding test is deemed to have failed, indicating that a leak or sealing defect still exists in the chamber, and simple gas replenishment has not fundamentally solved the problem.

[0104] Concentration verification can be performed during or after the pressure holding test by re-detecting the real-time gas concentration in the target gas chamber using the concentration detection module 140, and comparing the detection result with the initial gas concentration or the preset target concentration. If the real-time gas concentration is not lower than the preset lower limit, the concentration verification is deemed successful, confirming that the gas composition in the chamber has returned to the performance level required by the design. If the real-time gas concentration is lower than the preset lower limit, the concentration verification is deemed unsuccessful.

[0105] Furthermore, if either the pressure holding test or the concentration verification fails, the verification unit 154 generates a maintenance alarm message and outputs the target gas chamber number, the fault type of pressure holding failure or concentration non-compliance, and historical repair records to the control module 150. This prompts maintenance personnel to perform targeted repairs on the sealing structure of the target gas chamber, rather than repeatedly performing ineffective gas replenishment operations. Only when both the pressure holding test and the concentration verification pass will the verification unit 154 mark the target gas chamber as repair complete, allowing the target gas chamber to resume monitoring and circulation.

[0106] The verification unit 154 verifies the repair effect through pressure holding test and concentration verification to ensure that each repair truly restores the sealing performance and thermal performance of the chamber, avoiding repeated inflation and energy waste caused by incomplete repair, and ensuring the long-term reliability and energy-saving effect of the multi-cavity curtain wall 110.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
