Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle detection, and particularly relates to a 18-metal halogen lamp vehicle sunlight simulation system. Background Art

[0002] With the development of the automotive industry, the demand for vehicle environment simulation testing has been increasing day by day. In particular, sunlight simulation testing is crucial for verifying the weather resistance of vehicle materials, the stability of electronic devices, and driving safety.

[0003] Traditional vehicle sunlight simulation systems simulate the full-spectrum characteristics of sunlight (especially in the ultraviolet, visible, and infrared bands) through artificial light sources (such as metal halogen lamps, xenon lamps, LEDs, etc.), and adjust the light distribution by combining optical reflection, filters, and other devices.

[0004] However, traditional vehicle sunlight simulation systems lack real-time monitoring and intelligent maintenance mechanisms for the working state of light sources, resulting in easy damage to the equipment due to overheating or long-term high-load operation, increasing downtime, and thus affecting the operation efficiency of the vehicle sunlight simulation system. For example, when a metal halogen lamp works at a high temperature, if heat dissipation is insufficient or the abnormal state is not handled in time, it may cause light intensity attenuation, shortened lifespan, or even failure shutdown. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a 18-metal halogen lamp vehicle sunlight simulation system, which solves the above problems.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A 18-metal halogen lamp vehicle sunlight simulation system, comprising:

[0012] A heat dissipation judgment module, which is used to judge whether the heat dissipation of the metal halide lamp is in a normal working state according to the heat dissipation evaluation index;

[0013] An association analysis unit. If the metal halide lamp is not in a normal working state, the association analysis unit is used to judge the correlation between the working state of the metal halide lamp and the heat dissipation state of the metal halide lamp according to the metal halide lamp abnormality index and the heat dissipation evaluation index; among them, the correlation includes strong correlation and weak correlation;
