Abstract

The invention discloses an alcohol gas concentration laser telemetering device comprising a laser device control and emission system and a signal receiving, analysis and display system, wherein the laser device control and emission system comprises a modulating signal generator which is connected with a laser controller, a diode laser device and a laser emission device in sequence; the signal receiving, analysis and display system comprises a phase lock amplifier, a data acquisition and analysis device, a system display and alarm device and a laser receiving device, wherein the phase lock amplifier is respectively connected with the modulating signal generator, the laser emission device, the data acquisition and analysis device and the laser receiving device; and the output end of the data acquisition and analysis device is connected with the input end of the system display and alarm device. The invention can remotely carry out predetection on alcohol content in the air in a vehicle, thereby improving the pertinence and the accuracy of drunk driving checking, improving the enforcement work efficiency and reducing the police strength application.

Description

technical field [0001] The invention relates to an ethanol gas detection device, in particular to a laser remote measurement device for ethanol gas concentration. Background technique [0002] Driving a motor vehicle under the influence of alcohol is a socially harmful behavior that disregards the personal safety of oneself and others. Tragedy caused by drunk driving occurs every day. The public security traffic management department has also invested a lot of police force in key time periods and locations to investigate this and drunk driving behavior. Driving can only be checked by casting a net, which is not only inefficient, but also affects the normal traffic order. [0003] The traditional alcohol concentration detection instrument - "breath alcohol detector" adopts the principle of electrochemistry, which can accurately detect the alcohol content of the gas. The principle is that when an oxide with N-type conductivity is exposed to the atmosphere, it will reduce the...
