Description

565696 V. Description of the invention (1) [Creation area] This creation is about a gas simulation system, especially a breath alcohol simulation system that can simulate various human exhalation concentrations, so it is used to detect and correct a breath alcohol analysis. instrument.

I [Creative background] At present, traffic accidents caused by drunk driving have risen to the top ten causes of traffic accidents in Taiwan. There are currently two methods for analyzing alcohol concentration in law enforcement. One is the alcohol concentration in the blood, and the other One is the alcohol concentration in the breath, the former is used by the forensic community, and the latter is the breath alcohol analyzer used by countries in traffic law enforcement. In theory, alcohol is taken by the body to the organs after being absorbed by the body, and then discharged through the fluid, sweat, and breath. Excessive drinking will reduce driving ability, weaken vision, slow response, and poor judgment. The amount of alcohol for each person is different, which is controversial, so scientific analysis methods have become an important basis for national regulations. China's regulations restrict drivers' breath alcohol concentration to not exceed 0.25 mg / 1 (0.25 mg per liter), if it exceeds 0.55 mg / 1 (0.55 mg per liter), a penalty has been involved . Therefore, in view of the handling of cases of "excess alcohol concentration" in the traffic management penalty regulations, the relevant domestic authorities have established a set of "exhalation alcohol analyzers" in accordance with national standards for inspection and inspection regulations, and with reference to international norms (OIML R126) and practices. The standard verification system for testers and testers ", through the system's precision measurement instrument analysis and testing, provides standard verification values for related instrument testing, which can meet the requirements for banning breath alcohol analyzers and tests for drunk driving in China.

Ensuring that the certificate system cooperates with the internal breath method and related guarantees for the analysis of public safety and the Republic of China. The eighty-nine instruments that can follow the specifications and respect the fairness of people ’s tolerance, including the simulation of alcohol consumption, measure people ’s lives. The specifications for the application and inspection of the eighty-six instruments are in line with domestic rights and interests, and the exhalation wine regulations are accurate and meet the regulatory body standards. All instruments required for the transaction weighing instrument are required to be safe. The Breath of the Breath Wine Year, the commissioned inspection of grass and tolerances, was officially announced and also strengthened.
