Description

Technical Field

[0001] The invention relates to the technical field of test equipment, and in particular to a full-day editable lighting simulation system. Background Art

[0002] Optical measurement is a non-contact measurement technology that uses some basic properties of light, such as reflection, interference, and scattering, to perform relevant precise measurements. The main principle is to use the physical properties of light to detect the measured object, and different measurement methods use different properties. Optical measurement is widely used in various fields such as industry, medicine, environmental science, physics, agriculture, and military, and has achieved many major results, but there are still some challenges, such as how to improve measurement accuracy, how to process large amounts of data, and how to achieve fast measurement.

[0003] When testing aerial objects, they will not only be exposed to direct sunlight, but also to reflection from the earth, clouds, and atmospheric scattering, so a more realistic simulation of the aerial radiation environment is required. Conventional solar simulators can only simulate direct sunlight, but cannot simulate lighting environments such as clouds and atmospheric scattering.

[0004] Therefore, in view of the above shortcomings, it is necessary to provide an all-day editable lighting simulation system. Summary of the invention

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] All-day editable lighting simulation system, combined with Figure 1 , Figure 2 A main light source 1 composed of a solar simulator is arranged in an indoor experimental field, a reflector 2 is arranged outside the output end of the main light source 1 to reflect the main light source 1 to a distant object under test, an environmental simulation light source 3 is arranged on the roof above the object under test and on the ground below, and a detection system 4 is arranged outside the object under test, wherein the main light source 1, the environmental simulation light source 3 and the detection system are all controlled by a control console 5.

[0022] Combination Figure 2 , Figure 3 As shown in the following table, according to the maximum irradiance of the main light source 1 of 0.2 solar constant, the environmental simulation light source 1 needs to form an irradiance of 400 to 3200 lx near the object being measured.

[0023]

[0024]

[0025] The environmental simulation light source 3 is designed to use a 300W xenon lamp as the light source, with 20 lamps per circle forming a circle with a diameter of 3m, and a uniform light glass is installed outside the xenon lamp. By arranging the environmental simulation light source 3 on the ground and the roof, a uniform irradiation of 400 to 3200lx can be formed near the object to be measured to simulate the scattered light environment of the object to be measured in the air. The light source is equipped with a programmable power supply and control software, and the functions of turning the light source on and off and adjusting the illumination can be realized in the console 5. The detection system 4 is equipped with an illuminance meter, which controls the environmental light source for different test scenes, measures in all directions of the installation position of the object to be measured, and obtains the environmental simulation illumination values ​​of different test scenes.

[0026] The measurement process is to first decompose the task into visible light scattering characteristics measurement and laser scattering characteristics measurement. After selecting the visible light scattering characteristics measurement, it is necessary to input the measurement angle. The system will automatically set the turntable operation parameters according to the measurement angle definition. Then, according to the actual situation of the task, according to different test scenarios, the test simulation time, measurement location (longitude, latitude and altitude) and environmental parameters (cloudless or cloudy) are selected on the console 5. The solar simulation parameters and ambient light simulation parameters are automatically calculated, the light source is controlled to realize parameter simulation, the visible light image is obtained, and the visible light scattering characteristics data are obtained through data processing.
