[0002] In the construction industry, the performance of building windows has a crucial impact on the overall energy efficiency, comfort, and safety of buildings. For example, the thermal insulation performance of windows directly affects the regulation of indoor temperature. Good thermal insulation performance can reduce the use of air conditioning and other cooling and heating equipment, thus reducing energy consumption. The airtightness of windows is related to indoor air quality and the insulation effect of external noise. Therefore, conducting comprehensive and accurate performance tests on building windows is a key step in ensuring that they meet the requirements for building use.

[0003] In the process of testing building exterior windows, the windows are usually installed on a test chamber, and the test data is analyzed by various sensors installed inside to determine the performance of the building exterior windows. However, the installation and disassembly of sensors in traditional building exterior window testing devices is cumbersome and complicated, usually requiring multiple tools and steps to complete. This not only consumes a lot of time but also increases the labor intensity of operators. Furthermore, the sensors are more prone to damage during frequent installation and disassembly, which in turn affects the accuracy of the test data.

[0011] As a preferred approach, the specific process of analyzing the changing trends of wind speed and illuminance data and comprehensively determining the causes of data anomalies is as follows: S101. Obtain the wind speed data sequence collected in the current time period. and illuminance data sequence ,in, and These represent the wind speed and illuminance values ​​at the i-th time point, respectively, where n is the number of data points collected during that time period. Additionally, historical wind speed data sequences are retrieved from the database. and historical illuminance data series , where m is the number of historical data points; S102.

Otherwise, the verification fails, and adjustments and optimizations are performed. S203. Output the judgment results and verification results in the form of a graphical interface.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up a quick-release mechanism, using gears, discs, fastening clips and L-shaped toothed plates, two adjacent fastening clips can be pushed towards each other and finally pressed against the outer surface of the base to fix the sensor, so that the sensor can be more securely installed on the mounting plate. When repairing or replacing the sensor, it is also easy to release the fastening clips from the base, so that the staff can remove the sensor from the mounting plate, thereby saving time, reducing the difficulty of operation and improving work efficiency.

[0014] (2) By setting the locking mechanism, the L-shaped connecting plate, the card block and the limiting block are designed to further lock the L-shaped toothed plate. The limiting block and the limiting groove can restrict the position of the L-shaped toothed plate, so as to avoid the L-shaped toothed plate from shifting during the subsequent test of the external window sample, which would cause the fastening clamp to fail to fasten the base and the sensor to loosen. This would reduce the test data error caused by the sensor loosening and ensure the accuracy of the test results. By utilizing the design of the first contact plate, the second contact plate, and the contact points, along with the indicator lights installed on the movable plate, operators can intuitively and quickly determine whether the L-shaped toothed plate has been fully reset based on the on / off status of the indicator lights. This intuitive feedback method avoids operational errors caused by subjective judgment mistakes, improves operational accuracy, simplifies the operation process, facilitates real-time monitoring of the installation process, and ensures installation quality.

[0015] (3) Temperature, humidity, wind speed and illuminance data are collected in real time by sensors installed inside the test chamber and integrated to form basic environmental data containing time series information of each parameter. Temperature data is compared with preset standard temperature thresholds and humidity data is compared with preset standard humidity thresholds. According to the comparison results, data exceeding the thresholds are judged as abnormal data. At the same time, wind speed and illuminance data collected in the same period are obtained. Historical environmental data is obtained from the database. A multi-dimensional correlation analysis algorithm is used to analyze the changing trends of wind speed and illuminance data in combination with historical environmental data. The cause of data abnormality is judged comprehensively. The judgment result is verified according to the preset verification rules. After the verification is passed, the cause of data abnormality is output in the form of a graphical interface. By analyzing the changes in wind speed and illuminance and fully considering their internal relationship, the cause of data abnormality can be judged more accurately, thereby avoiding misjudgment and omission caused by single parameter judgment and improving the accuracy of abnormal judgment.

The slide bar 710 is fixedly connected to the upper end of the L-shaped toothed plate 709. A first spring 711 is fixedly connected between the L-shaped toothed plate 709 and the right end wall of the slide groove 701.

[0022] The locking mechanism 8 also includes a first connecting groove 801 opened at the upper left side of the L-shaped toothed plate 709, an L-shaped connecting plate 805 disposed in the first connecting groove 801, a slot 802 opened on the right side of the first connecting groove 801, a locking block 806 locked in the slot 802, a second spring 807 symmetrically fixedly connected to the L-shaped connecting plate 805, a moving plate 808 fixedly connected to each of the two ends of the second spring 807 that are far apart from each other, a second connecting groove 803 symmetrically opened in the first connecting groove 801, a moving plate 808 disposed in the second connecting groove 803, a limiting groove 804 opened in the second connecting groove 803, a limiting block 809 locked in the limiting groove 804, and the limiting block 809 fixedly connected to the moving plate 808.

[0023] The left side of the L-shaped connecting plate 805 is slidably connected to a first contact plate 812 and a second contact plate 813, and both the first contact plate 812 and the second contact plate 813 are provided with contacts 814 on opposite sides.

[0024] The following describes the working process of locking mechanism 8 locking L-shaped toothed plate 709 onto mounting plate 3, and quick-release mechanism 7 simultaneously securing multiple sensors 4: It should be noted in advance that the outer window sample 2 is installed on the front side of the test chamber 1, and a sealing strip is installed between the outer window sample 2 and the test chamber 1. The test chamber 1 is equipped with heating equipment, humidification equipment, air blowing equipment, and lighting equipment for testing the outer window sample 2, and is also equipped with a ventilation system that matches the air blowing equipment, such as... Figure 2 As shown, an installation plate 3 is fixedly installed between the inner walls on both sides of the front end of the test chamber 1. Four sensors 4 are equidistantly arranged on the installation plate 3, corresponding to the heating equipment, humidification equipment, air blowing equipment and light equipment, including temperature sensor, humidity sensor, wind speed sensor and light intensity sensor, which are used to collect temperature data, humidity data, wind speed data and light intensity data of the outer window sample 2 in real time during the test. It should also be noted that, such as Figure 2 and Figure 3 As shown, multiple grooves 6 are equidistantly spaced on the mounting plate 3. Each sensor 4 has a base 5 mounted on its bottom. The number of bases 5 is the same as the number of grooves 6, and the bases 5 are snapped into the grooves 6. Fastening clips 708 are symmetrically arranged above the mounting plate 3 with the grooves 6 as the center. The facing surfaces of two adjacent fastening clips 708 are pressed against the outer surface of the base 5, clamping the base 5 onto the mounting plate 3. Figure 4 and Figure 5 As shown, contacts 814 are provided on the opposing surfaces of the first contact plate 812 and the second contact plate 813, and initially the two contacts 814 are in contact with each other. An indicator light electrically connected to the contact 814 is installed on one of the movable plates 808. When the two contacts 814 lose contact, the indicator light is lit, and when the two contacts 814 are in contact with each other, the indicator light is turned off. When repairing or replacing sensor 4, such as Figure 2 , Figure 3 as well as Figure 4As shown, an L-shaped toothed plate 709 is slidably mounted on the front side of the mounting plate 3 via a sliding groove 701 and a sliding strip 710. A first connecting groove 801 is provided on the upper left side of the L-shaped toothed plate 709. Second connecting grooves 803 are symmetrically connected to the upper and lower sides of the first connecting groove 801. Limiting grooves 804 are connected to the opposite side of each of the second connecting grooves 803. A slot 802 is connected to the right side of the first connecting groove 801. An L-shaped connecting plate 805 is fixedly mounted on the left front side of the mounting plate 3. Initially, the L-shaped connecting plate 805 is positioned within the first connecting groove 801. A locking block 806, fixedly connected to the right side of the L-shaped connecting plate 805, is initially engaged within the slot 802. (Refer to...) Figure 4 As shown, movable plates 808 are fixedly connected to both the upper and lower sides of the L-shaped connecting plate 805 by second springs 807. The two movable plates 808 are respectively disposed within two second connecting slots 803, and each movable plate 808 has a limiting block 809 fixedly connected to its right end on the opposite side, which is adapted to the limiting slot 804. Initially, the limiting block 809 is tightly engaged in the limiting slot 804 by the elastic force of the second springs 807. When the sensor 4 needs to be repaired or replaced, and the fastening restriction on the sensor 4 needs to be released, the operator can operate the movable plates 808 to move the two movable plates 808 towards each other, thereby causing the limiting block 809 to move out of the limiting slot 804. At this time, the movable plates 808 simultaneously move in opposite directions. The second connecting plate 805 moves within the second connecting groove 803, compressing the second spring 807. By removing the limiting block 809 from the limiting groove 804, the restriction of the L-shaped connecting plate 805 on the L-shaped toothed plate 709 can be initially released. Since the L-shaped toothed plate 709 is slidably mounted on the front side of the mounting plate 3 via the sliding groove 701 and the sliding strip 710, while releasing the locking relationship between the limiting block 809 and the limiting groove 804, the operator can simultaneously push the L-shaped toothed plate 709 to the right, moving it from the left end to the right end of the mounting plate 3. Simultaneously, as the L-shaped toothed plate 709 moves to the right, the locking block 806 will also move out of the locking groove 802, ultimately releasing the contact between the L-shaped connecting plate 805 and the L-shaped toothed plate 709. (Refer to...) Figure 4 Furthermore, because the lower end of the L-shaped toothed plate 709 is toothed and meshes with multiple gears 704 located below the mounting plate 3, when the L-shaped toothed plate 709 moves to the right, the meshing between the teeth drives the gears 704 to rotate synchronously. A rotating shaft 703 is fixedly mounted on the axis of the gear 704, and the rotating shaft 703 is rotatably mounted at the bottom of the mounting plate 3. A disc 705 is fixedly mounted on the outer surface of the middle part of the rotating shaft 703. When the gear 704 is driven to rotate by the L-shaped toothed plate 709, the rotating shaft 703 mounted on its axis rotates synchronously at the bottom of the mounting plate 3, driving the disc 705 to rotate synchronously between the mounting plate 3 and the gear 704. Figure 3As shown, the top of the disc 705 has two equally spaced arc-shaped grooves 706. A sliding column 707 is vertically and upwardly connected within each arc-shaped groove 706. The sliding column 707 is slidably connected to the mounting plate 3 through a through groove 702. The through groove 702 is symmetrically opened on the mounting plate 3 with the bottom groove 6 as its axis. Therefore, the sliding columns 707 are synchronously and symmetrically arranged at both ends of the bottom groove 6. The base 5, which is mounted on the bottom of the sensor 4, is snapped onto the mounting plate 3 through the bottom groove 6. Therefore, the fastening clips 708 fixedly connected to the top of the sliding column 707 are synchronously and symmetrically arranged on the base 5. On both sides, the fastening clamp 708 is initially in close contact with the outer surface of the base 5. When the disc 705 rotates, the change in position of the arc groove 706 can push the sliding column 707 to slide synchronously between the arc groove 706 and the through groove 702, and drive the fastening clamp 708 to move in the opposite direction (outward), so that the fastening clamp 708, which was initially in contact with the outer surface of the base 5, gradually loses contact with the base 5, thereby releasing the fastening restriction of the fastening clamp 708 on the base 5, making it easier for the staff to remove the sensor 4 from the mounting plate 3; When installing sensor 4, first snap the base 5 of sensor 4 into the bottom groove 6. Then, reverse the operation, moving the L-shaped toothed plate 709 from the right end to the left end of the mounting plate 3, controlling the two moving plates 808 to move towards each other, and simultaneously pushing the L-shaped toothed plate 709 to insert the L-shaped connecting plate 805 into the first connecting groove 801, so that the locking block 806 is engaged in the locking groove 802. At this time, release the moving plate 808, and under the elastic force of the second spring 807, the limiting block 809 is engaged in the limiting groove 804 to lock the L-shaped connecting plate 805, positioning the L-shaped toothed plate 709 on the mounting plate 3. At the same time, because the L-shaped toothed plate 709 is reset, the teeth interact with each other. When engaged, the controllable disc 705 rotates in the opposite direction, pushing the two adjacent fastening clips 708 toward each other and finally fitting tightly against the outer surface of the base 5, thereby fixing the sensor 4 and allowing the sensor 4 to be more securely installed on the mounting plate 3. By further locking the L-shaped toothed plate 709 with the locking mechanism 8, the position of the L-shaped toothed plate 709 can be restricted by the design of the limiting block 809 and the limiting groove 804, so as to avoid the L-shaped toothed plate 709 from shifting during the subsequent test of the outer window sample 2, which would cause the fastening clips 708 to fail to fasten the base 5, causing the sensor 4 to loosen and affecting the accuracy of the test data. Reference Figure 4 and Figure 5As shown, a sleeve 810 is fixedly installed at the bottom left end of the upper movable plate 808. An inner rod 811 is vertically slidably connected inside the sleeve 810, and the inner rod 811 is fixedly connected to the lower movable plate 808. A first contact plate 812 is fixedly connected to the bottom of the sleeve 810, and a second contact plate 813 is fixedly connected to the top of the inner rod 811. Both the first contact plate 812 and the second contact plate 813 are slidably disposed on the left side of the L-shaped connecting plate 805. The second contact plate 813 is also slidably connected to the sleeve 810 through it. As mentioned above, when the operator controls the two movable plates 808 to move towards each other, the sleeve 810 and the inner rod 811... When the positions change synchronously, the inner rod 811 will slide against the sleeve 810, and the second contact plate 813 will slide synchronously through the sleeve 810. At this time, the first contact plate 812 and the second contact plate 813 will also slide synchronously on the left side of the L-shaped connecting plate 805. Through the sliding connection with the L-shaped connecting plate 805, the movement of the sleeve 810 and the inner rod 811 can be supported. The facing surfaces of the first contact plate 812 and the second contact plate 813 are provided with contact points 814, and the two contact points 814 are initially in contact with each other. On the upper moving plate 808, there are fixed objects corresponding to the contact points 814. The indicator light for the interconnection is off when the two contacts 814 are in contact, and on when they are out of contact. Therefore, when the operator controls the two moving plates 808 to move towards each other, the first contact plate 812 moves downwards and the second contact plate 813 moves upwards, moving the two plates away from each other and causing the two contacts 814 to simultaneously lose contact, at which point the indicator light illuminates. When the L-shaped toothed plate 709 is reset and installed so that the limiting block 809 re-engages in the limiting groove 804, if the reset is correct, the limiting block 809 should be able to engage in the limiting groove 804. The first contact plate 812 and the second contact plate 813 move towards each other, re-engaging the two contacts 814. At this time, the indicator light goes out. However, if the reset is not complete, the first contact plate 812 and the second contact plate 813 cannot re-engage the two contacts 814, so the indicator light remains on. The operator can judge whether the L-shaped toothed plate 709 has been completely reset based on the real-time status of the indicator light. This intuitive feedback method avoids operational errors caused by subjective judgment mistakes, improves the accuracy of operation, simplifies the operation process, facilitates real-time monitoring of the installation process, and ensures installation quality.

[0025] Embodiment 2 of the present invention: Please refer to Figure 6 As shown, it also includes an intelligent control system, which includes a data acquisition unit, a correlation analysis unit, and a verification output unit. The data acquisition unit is used to collect temperature, humidity, wind speed, and illuminance data in real time during the test by sensors 4 installed inside the test chamber 1, and integrate them to form basic environmental data containing time series information of each parameter, and send it to the correlation analysis unit.

[0028] Sensors installed inside the test chamber collect and integrate real-time temperature, humidity, wind speed, and illuminance data during the test process, forming basic environmental data containing time-series information for each parameter. Temperature and humidity data are compared to preset standard temperature and humidity thresholds. Data exceeding these thresholds are identified as abnormal.
