Abstract: Through the development and application of the near-infrared spectrometric rapid detection system for light oil products, the traditional inspection of light oil in the laboratory is replaced, the batch automatic sampling, rapid detection, automatic cleaning, machine replacement and unattended inspection of the inspection business are realized, the problems of low efficiency, large workload and high cost of traditional inspection are solved. Using the system the artificial detection environment of toxic and harmful substances are improved, the product quality information are provided timely and accurately, the device to optimize and adjust the production process parameters effectively is guided, the rational use of resources and the optimization and upgrading of production process are promoted. All these meets the needs of enterprise production device refined management and optimized operation, and drives the rapid detection technology innovation and development of light oil products in the industry.
