Detection amplification circuit based novel alcohol detector

Abstract

The invention discloses a detection amplification circuit based novel alcohol detector. The detector mainly comprises a central processor, a power supply, an illumination driving circuit, a memory, a display, an alarm, an alcohol detection module, a camera and an illumination lamp, wherein the power supply, the illumination driving circuit, the memory, the display, the alarm, the alcohol detection module and the camera are connected with the central processor respectively; and the illumination lamp is connected with the illumination driving circuit. The detector is characterized by being further provided with a detection amplification circuit with an input end connected with a signal output end of the camera and an output end connected with the central processor. According to the detector, face portrait information of a detected person can be extracted, so that the convenience is brought for law enforcement work of related law enforcement departments. The detector is provided with the detection amplification circuit, and the detection amplification circuit can separate out an image signal to block an interference signal and amplify the image signal to avoid the interference of signal image display definition.

Description

technical field [0001] The invention relates to a detector, in particular to a novel alcohol detector based on a detection amplifier circuit. Background technique [0002] Today, the traffic law enforcement department has continuously strengthened the investigation and punishment of drunk driving, in order to effectively reduce the vicious traffic accidents caused by drunk driving. During the investigation, it usually uses an alcohol detector to check the alcohol concentration of the driver's breath and This is used as the basis for whether the driver is drunk or not. However, the existing alcohol detectors cannot timely extract the facial head image information of the detected person, which brings certain inconvenience to the law enforcement work of the relevant law enforcement departments. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the traditional alcohol detector cannot timely extract the facial image informat...
