Description

Technical Field

[0001] This utility model relates to the field of gas spectral analysis technology, and in particular to an automated calibration and storage device for gas spectral databases. Background Technology

[0002] Gas spectroscopy is a technique that uses the light absorption characteristics of gas molecules to detect and identify gases. Its core principle is that when light of a specific wavelength shines on gas molecules, the molecules absorb this light energy and convert it into heat energy, causing the gas molecules to heat up and produce pressure changes. These pressure changes generate sound, and by measuring and analyzing these sounds, the composition and concentration of the gas can be determined.

[0003] Existing gas calibration equipment typically employs a discrete design, with the light source system, detection module, and data processing unit operating independently. This results in bulky equipment and poor coordination among components. Such a dispersed layout not only increases system complexity but also affects calibration efficiency and measurement accuracy. In particular, when frequent changes in calibration gas or adjustments to detection parameters are required, the operation process becomes cumbersome and fails to meet the demands of modern industry for rapid detection. To address this, we propose an automated calibration and storage device for a gas spectral database. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies, such as conventional light source systems that rely on fixed wavelengths or manual light source replacement, which fail to achieve rapid and accurate spectral switching. While some devices are equipped with multiple light sources, they lack effective sealing measures, leading to gas chamber leakage during rotation and switching, affecting the accuracy of calibration results. Existing calibration devices often neglect heat dissipation design in their storage systems, making them prone to data loss or storage device damage due to overheating during prolonged continuous operation. Especially when storing large amounts of spectral data simultaneously, the insufficient heat dissipation performance of traditional storage modules severely impacts system reliability. Traditional calibration gas paths typically employ a single pipeline design, with calibration gas and clean gas sharing a common channel, easily causing cross-contamination. Exhaust gas treatment systems are often rudimentary, with most emissions being directly discharged, failing to meet environmental protection requirements and potentially affecting the accuracy of subsequent calibration results. Therefore, this invention proposes an automated calibration and storage device for a gas spectral database.
