Description

Technical Field

[0001] The utility model relates to the technical field of dust concentration measurement, in particular to an adjustable reflector structure. Background Art

[0002] Dual-optical path dust concentration measurement involves the field of optical measurement and environmental monitoring. It is a technology that measures dust concentration in the air by optical methods. Dual-optical path dust concentration measurement is mainly based on the principle of light scattering. Dust particles in the air will scatter light. The intensity of the scattered light is related to the concentration of dust particles. By measuring the intensity of the scattered light, the dust concentration can be inferred.

[0003] A dual optical path measurement system generally consists of two independent optical paths:

[0004] Measuring light path: used to actually measure the dust concentration in the air. The light beam emitted by the light source passes through the measurement area, the dust particles scatter the light, and the receiver measures the intensity of the scattered light.

[0005] Calibration optical path: The calibration optical path is parallel to the measurement optical path and is used to compensate for factors such as changes in light source intensity and ambient light interference to ensure the accuracy of the measurement results. The light beam of the calibration optical path does not pass through the measurement area and is directly received by the receiver to correct the signal of the measurement optical path.

[0006] At present, the reflectors in the dual optical path system usually use fixed reflectors. Once the installation position of the fixed reflector is determined, it cannot be precisely adjusted. If the system parameters or external environment change, it cannot respond flexibly, which may cause optical path deviation or system performance degradation; slight errors in the installation process may cause the optical path to deviate from the designed path. The fixed reflector cannot be adjusted and cannot effectively compensate for these errors, affecting the system accuracy; once the fixed reflector is damaged or surface contaminated, the repair and replacement process is complicated and the entire system may need to be recalibrated, increasing the difficulty and cost of maintenance; fixed reflectors cannot adapt to different application requirements. If the optical path needs to be changed or the system function needs to be adjusted, it is usually necessary to redesign and manufacture the reflector, which increases time and economic costs.
