Problems solved by technology

Therefore, if the measurement is carried out step by step according to the above test items, a complete metrological verification measurement process requires a total of 52 breath measurements on the tested alcohol detector on the verification device. The measurement results on the tester are transcribed to paper or computer software. According to the concentration of standard alcohol gas set on the test device and the measurement results of the alcohol tester, the test report is compiled into a test report after statistical analysis, and a conclusion of whether the test is qualified or not is obtained. , therefore, the current verification method is cumbersome and error-prone

Abstract

The invention provides an alcohol detector metrological verification method for photographing and recording a measurement result. According to the method, an alcohol detector verification device and a visual identification device are both in communication connection with the computer, and therefore data communication is achieved; 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 a reading value image shot by the visual identification device; and the verification personnel identifies the reading value according to the reading value image. By adopting the alcohol detector metrological verification method, a more accurate standard alcohol gas concentration value can be obtained, on the other hand, the reading value image is recorded on the management system software, so that the verification personnel can conveniently and manually identify the measurement result to obtain the reading value, and the reading value can be used as an original evidence of the measurement result, thereby ensuring the authority of a verification report, and preventing the verification result from being manually modified.

Description

technical field [0001] The invention relates to the technical field of verification of breath alcohol detectors, in particular to a method for measuring and verifying alcohol detectors by taking photos and recording measurement 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 ) is measured as follow...
