Alcohol detector metrological verification management method capable of automatically identifying detection result

Abstract

The invention provides an alcohol detector metrological verification management method capable of automatically identifying a detection result. According to the method, an alcohol detector verification device and a visual identification device are both in communication connection with a computer, so as to realize data communication; management system software on the computer can obtain a concentration value of a standard alcohol gas output by a blowing port of the alcohol detector verification device; and visual identification software on the computer can obtain a reading value image shot by the visual identification device, processes the reading value image to obtain a reading value and transmits the reading value to the management system software. By adopting the alcohol detector metrological verification management method, a more accurate standard alcohol gas concentration value can be obtained, and a reading value is obtained and transmitted to the management system software based on a machine automatic identification technology, so that the working efficiency is greatly improved compared with all manual identification; the problems that the manual recording process of verification personnel is tedious and errors are prone to occur can be avoided; and on the other hand, automation of the verification process is facilitated, and manual modification of the verification result is prevented.

Description

technical field [0001] The invention relates to the technical field of calibration of exhaled gas alcohol content detectors, in particular to a measurement and verification management method for alcohol detectors that automatically recognizes detection results. Background technique [0002] The exhaled breath alcohol detector, referred to as the alcohol detector, is a tool used by the traffic police for law enforcement. [0003] When the metrology department conducts metrological verification of alcohol detectors, it must follow the regulations for the measurement and verification of alcohol detectors (JJG657-2019). According to the requirements of the regulations, standard alcohol gas is needed in the verification process, which generally comes from the standard alcohol gas produced by the first-grade standard gas in the cylinder or the ethanol generator device, and the indication error (including the absolute error of the indication and the relative error of the indication...
