This invention relates to the field of pollutant detection technology, and more particularly to a pollutant detection method and system based on an environmental consulting knowledge base. The method includes: receiving basic information about the project to be tested, inputting it into a pre-built environmental consulting knowledge base for matching, and outputting a preliminary detection plan; generating a final detection plan after verification using historical cases; performing on-site sampling and in-situ testing, linking the knowledge base to complete real-time quality control early warning and on-site calibration, and obtaining a calibrated in-situ detection dataset; performing laboratory testing on environmental samples and performing three-level calibration to obtain a valid pollutant detection dataset; performing compliance analysis on the valid detection data, and outputting the detection results. This invention effectively solves the core problems of fragmented processes and lack of unified knowledge support in existing detection technologies, overcomes the shortcomings of manual reliance, insufficient quality control and calibration, low data accuracy, and poor analysis efficiency, and achieves intelligent standardization of the entire detection process, significantly improving detection efficiency and data accuracy.

This invention relates to the field of detector operating temperature determination technology, and more particularly to a method for determining the optimal operating temperature of a spectrometer detector. The method includes the following steps: performing theoretical analysis to determine the signal-to-noise ratio (SNR) formula, analyzing the relationship between detector signal and temperature, and the relationship between detector noise and temperature, and theoretically calculating the SNR-temperature relationship; simultaneously performing laboratory measurements, including experimental setup and data acquisition and calculation; and finally, combining the theoretical calculations and the actual measured SNR results to determine the optimal operating temperature of the InGaAs detector. This invention can obtain the operating temperature at which the InGaAs detector achieves the highest SNR. When using the InGaAs detector for measurements, a temperature control module is used to stabilize the InGaAs detector at this temperature, resulting in better performance of the short-wave infrared spectrometer based on the InGaAs detector and improved instrument measurement accuracy.
