A control console 3 is mounted on the closed plate 2, and a fixing mechanism is installed between the closed plate 2 and one side of the housing 1. A support mechanism is installed inside the housing 1, and a moving mechanism is installed inside the housing 1 at the upper end of the support mechanism. Through the connection of the housing 1 with the closed plate 2, the fixing mechanism, the support mechanism, the moving mechanism, and the closed plate 2 and control console 3, the opening and closing of the test chamber, parameter control, sealing and fixing, sample support, and movement of the light-emitting components are easily realized, meeting the basic requirements of sunlight simulation testing. The fixing mechanism includes a limiting block 4 rotatably mounted on one side of the closed plate 2, with a torsion spring installed between the limiting block 4 and the closed plate 2, and a positioning mechanism is provided inside the limiting block 4. Block 6, positioning block 6 and limiting block 4 are equipped with a first telescopic spring 7, and a fixing rod 5 is fixedly connected to the upper end of the device housing 1 of positioning block 6. Through the sealing plate 2, limiting block 4, first telescopic spring 7 and positioning block 6, the sealing plate 2 and device housing 1 are stably fixed, preventing the sealing plate 2 from being accidentally opened during the test. The support mechanism includes a movable frame 8 that is vertically and equidistantly fixed to both sides inside the device housing 1. One end of the movable frame 8 is vertically fixed with a snap-fit ​​rod 17. The lower end of the snap-fit ​​rod 17 is provided with grooves at equal intervals. The grooves are movably snap-fitted with a fixing block 10. A second telescopic spring is installed between the fixing block 10 and the snap-fit ​​rod 17. Through the movable frame 8, snap-fit ​​rod 17, fixing block 10 and second telescopic spring, the support plate 9 is provided with an installation and adjustment base, so as to fix and adjust the height of the support plate 9.

[0017] In this invention, a support plate 9 is slidably arranged in the movable frame 8. The support plate 9 has a movable positioning opening, and movable rollers are rotatably installed on both sides of the support plate 9 between the movable frame 8. Through the movable frame 8, the support plate 9, and the movable rollers, the support plate 9 can slide smoothly and be accurately positioned, and the placement height of the test sample can be flexibly adjusted. The moving mechanism includes a support plate 13 that is horizontally slidably installed inside the device housing 1. The middle of the support plate 13 horizontally passes through the movable block 12, and an electric telescopic rod 16 is laterally slidably installed on the device housing 1 at one end of the support plate 13. The telescopic end of the electric telescopic rod 16... A screw rod 14 is longitudinally connected to one end of a movable block 12 via a threaded sleeve. A servo motor 15 is longitudinally slidably installed inside the housing 1 at one end of the screw rod 14. The output end of the servo motor 15 is coaxially fixed to one end of the screw rod 14. Through the servo motor 15, the screw rod 14, and the electric telescopic rod 16, the illuminating component can be moved precisely in the horizontal and vertical directions. A light plate 11 is fixedly connected to the lower end of the movable block 12. Through the movable block 12 and the light plate 11, the light plate 11 can be adjusted in position with the movable block 12 to accurately align with the test sample and simulate different sunlight irradiation conditions.

[0018] Working principle: In the use of this invention, firstly, according to the height of the test sample, the support plate 9 is pulled outward, and then inserted into the movable frame 8 of different heights according to the height of the test sample. At the same time, after the support plate 9 is inserted into place, the fixing block 10 is lifted, thereby fixing the position of the support plate 9 through the second telescopic spring in the groove of the snap-fit ​​rod 17. Then, the test sample is placed on the support plate 9, and then the closing plate 2 is rotated according to the hinge point, so that the closing plate 2 is completely attached to the outer shell 1 of the device. At the same time, during the attachment, the limiting block 4 rotates around the hinge, causing the positioning block 6 to move downward. When the attachment is complete, the limiting block 4 is released. The positioning block 6 and the fixing rod 5 are engaged by the torsion spring and the first telescopic spring 7. Then, the control console 3 starts the illumination plate 11 to conduct a sunlight test. At the same time, according to different sunlight simulation requirements, the control console 3 can be rotated to the "lateral movement" mode. At this time, the electric telescopic rod 16 extends and retracts, driving the moving block 12 to move laterally along the support plate 13. When "vertical movement" is required, the servo motor 15 is started, and the screw 14 is driven to rotate through the output end, thereby causing the moving block 12 to move longitudinally. Thus, the illumination plate 11 moves according to the requirements to simulate different sunlight conditions.

The data acquisition module monitors the temperature, humidity, and temperature inside the chamber. Gas concentration data is collected and transmitted to the analysis module. The analysis module receives the data from the acquisition module and preprocesses it, based on the temperature, humidity, and other parameters before and after the door is opened. Gas concentration changes, calculate temperature, humidity and When the change in gas concentration per unit time reaches a preset threshold, an early warning signal is generated and transmitted to the execution module; and based on the change in gas concentration per unit time and the corresponding threshold, the remaining time to reach the critical value is obtained. The collected data was sorted according to the collection time, and corresponding items collected at the same time were sorted. averaging the data and standard deviation The calculation, and the mean obtained from the calculation. and standard deviation Collect data fluctuation range for corresponding items The system is configured to compare the collected data for a given item with its fluctuation range, mark data outside the fluctuation range as outliers, and record the number of outliers. ,like If the collected data is abnormal, the data will be re-tested; if If outliers are removed, the mean of the remaining corresponding test data after outlier removal is calculated. The calculation, and the mean obtained from the calculation. As the corresponding data detected at the corresponding time; Re-examine the corresponding data; if the comparison result is still negative... If the problem is detected, it is determined that the acquisition device is malfunctioning, an equipment warning signal is generated, and the equipment warning signal is transmitted to the execution module. After receiving the device warning signal, the execution module controls the buzzer module of the intelligent control component to emit a buzzer warning and displays "Data Acquisition Device Abnormal" on the display screen of the control console 3, so that staff can perform timely maintenance operations on the device.
