Description

Technical Field

[0001] This invention relates to the field of sunlight simulation technology, and specifically to a sunlight simulation system and control method. Background Technology

[0002] Existing sunlight simulation systems can simulate the entire process from sunrise to sunset and can move freely on a support track. These systems are typically equipped with filtering and homogenizing systems to ensure the quality and stability of the simulated sunlight. However, in practical use, the following problems arise:

[0003] 1. The attenuation of lamp light often leads to significant differences in test repeatability. The attenuation of the lamp's light spectrum not only affects the photothermal activity per unit area, impacting measurements such as those of a vehicle's air conditioning system, but also affects tests such as ultraviolet aging tests. Infrared and ultraviolet light cannot be distinguished by the human eye, so strictly speaking, this type of test is unacceptable.

[0004] 2. There is a lack of unified evaluation standards for lamps, so it is impossible to determine whether they are qualified or not. They can only be selected and used based on the parameters provided by the manufacturer.

[0005] 3. When a lamp is nearing damage, it is often not detected immediately. It is only easily discovered after it is completely damaged, which reduces the accuracy of the test or renders the test invalid, wasting time and money. Summary of the Invention

[0006] One of the objectives of this invention is to provide a sunlight simulation system and control method that can monitor the spectral composition and lifespan of lamp tubes, thereby avoiding the problem of unqualified tests caused by the corresponding spectral composition and lifespan of lamp tubes not meeting the test requirements.

The side camera is used to photograph all the sunlight simulation lamp modules. The bottom camera is positioned directly below the sunlight simulation lamp modules, and the camera window is positioned on the test platform corresponding to the bottom camera. The bottom camera photographs the sunlight simulation lamp modules through the camera window.

[0009] The processing module is used to receive the first lamp photo of the light group corresponding to the sunlight simulation lamp module above the test platform captured by the bottom camera before the test begins, and analyze whether the corresponding lamp group meets the test requirements.

[0010] Also used for receiving the lamp tube test photos of the lamp group corresponding to the sunlight simulation lamp module above the test platform when all the lamp groups meet the test requirements, and analyzing whether the lamp tube life of the corresponding lamp group meets the test duration based on the lamp tube test photos.

When all the lamp groups meet the test requirements, receive the lamp tube test photos of the lamp group corresponding to the sunlight simulation lamp module above the test platform captured by the bottom camera and the side camera, and analyze whether the lamp tube life of the corresponding lamp group meets the test duration based on the lamp tube test photos. S3. When the lifespan of all lamps meets the test duration, conduct the test and monitor the lamps corresponding to the sunlight simulation lamp module in real time using a side camera to identify lamps with damaged lamps and issue a warning signal.

5. The sunlight simulation control method according to claim 4, characterized in that: S1 includes: S10. Before the experiment begins, take a picture of the sunlight simulation lamp module above by using the bottom camera set directly below the sunlight simulation lamp module to obtain a picture of the first lamp tube emitting light for each lamp group. S11. Based on the corresponding first lamp light emission photograph, analyze the light spectrum components corresponding to the first lamp light emission photograph to generate light spectrum component information for each lamp group; S12. Based on the light spectrum component information corresponding to each generated light group, and based on the light spectrum component requirements corresponding to the test, determine whether the corresponding light spectrum component meets the test requirements. If yes, determine that the corresponding light group meets the requirements; otherwise, determine that the corresponding light group does not meet the requirements. Send a first replacement signal to the client and receive the corresponding first feedback signal.

6. The sunlight simulation control method according to claim 5, characterized in that: S2 includes: S20. When all the lamp groups meet the test requirements, the lamp group is continuously powered on and kept at a fixed position and angle with the bottom camera. The bottom camera and the side camera take pictures of the lamp group at preset time intervals, and take multiple sets of pictures in sequence. Based on the multiple sets of pictures, the lamp type corresponding to the lamp group in the pictures is identified. It is determined whether there is a light decay percentage curve corresponding to the lamp type in the lamp characteristic database. If so, the light decay percentage curve corresponding to the lamp type is retrieved from the lamp characteristic database; if not, the lamp type is determined to be an unused type. S21. When the judgment result is that the lamp type is an unused type, based on the multiple sets of photos, extract the corresponding light spectrum and fit the light decay percentage curve corresponding to the lamp of the lamp group, and save it to the lamp characteristic database. S22. At the same fixed position and angle, continuously monitor all light groups using a side camera and take test photos of the second lamp tubes corresponding to each light group. S23. Based on the photographs of the second lamp tubes in the test light emission of each lamp group, read the light spectrum corresponding to the middle position of the photographs of the second lamp tubes in the test light emission, and compare it with the retrieved light decay percentage curve or the fitted light decay percentage curve to obtain the attenuation coefficient of each lamp tube. S24. Based on the attenuation coefficient of the lamp tubes of each lamp group, determine whether the lifespan of the lamp tubes corresponding to each lamp group meets the requirements of the test duration. If not, determine that the lifespan of the corresponding lamp group does not meet the requirements, send a second replacement signal to the client, and receive the second feedback signal from the client. If yes, determine that the lifespan of the lamp tubes of the corresponding lamp group meets the requirements.
