INSPECTION METHODS AND APPARATUSES FOR LIQUIDS

摘要

A method and apparatus for inspection of liquids are disclosed. The method includes inspecting a liquid with a technique selected according to whether the package of the liquid is transparent, semi-transparent or opaque. If the package is transparent or semi-transparent, a Raman spectra technique is used; if the package is opaque, a technique using an electronic scale and a barcode reader is used. In some embodiments, the Raman spectra technique and the technique using barcode reader and electronic scale can be used independently for inspection of the liquid. The inspection apparatus according to the present disclosure has advantages, such as capability of material identification, rapid examination speed, small volume, light weight, portability, low cost, freedom from radiation, and simple maintenance. The method and apparatus according to the present disclosure are suitable for safety inspection in public places having a large number, and fast flow, of people.

1. A method of inspection of liquids, the method comprising:
determining whether a package of a liquid is transparent, semi-transparent or opaque; if the package of the liquid is transparent or semi-transparent, directing a laser-emitting end of a Raman spectra module at the transparent or semi-transparent package of the liquid,
operating the module to emit a laser beam at the liquid,performing Raman spectra analysis on the liquid, andcomparing Raman spectra information of the liquid with standard Raman spectra information in a database to obtain an analysis result of the liquid and identify material of the liquid; if the package of the liquid is opaque,
placing the liquid on an electronic scale to obtain weight information of the liquid,reading barcode information of the liquid with a barcode reader,retrieving standard weight information for the liquid from a database based on the read barcode information, andcomparing the weight information from the electronic scale with the standard weight information from the database to determine whether the liquid is dangerous or suspicious.
