Drug detector based on animal olfactory sensation

Abstract

The disclosed drug detector based on animal olfaction comprises: a CCD camera, a brain stereotaxic instrument, an electrode, a pre-amplification and filter circuit, a multiarm maze, and computer control and analysis system. Wherein, according to animal brain olfaction cortex neuron electric action, letting animal produce specific memory to volatile drug; random putting drug in small rooms of the maze to give prize stimulation for specific brain area and reinforce the memory till animal action includes statistic meaning, collecting relative induced brain electric information to input computer for recognition and analysis and form training database.

Description

technical field [0001] The present invention generally belongs to the field of intelligent detection and identification technology methods, and in particular relates to a drug detection device based on the sense of smell of animals. According to the analysis and judgment of animals on the specific electrical signal patterns induced by different gas molecules, the detection of items that are volatile and can induce animals to produce special olfactory stimuli, such as drugs, explosives, etc. It has the characteristics of high reliability, good specificity, time-saving, economical and objective indicators. Background technique [0002] The existence of drugs has brought disasters to the country and the people, and has been attacked and controlled by countries all over the world. It is necessary to carry out an unremitting and long-term effective struggle against drug crimes. However, as the main means of prevention, the methods and equipment for drug d...

Problems solved by technology

The first two types of methods mainly focus on laboratory chemical analysis, and carry out component identification and analysis on seized specimens; although they can be accurately measured, they require huge equipment and long detection cycles, and are more suitable for targeted, small-scale sample detection, but cannot meet the drug detection of a wide range of people, objects or areas

Anti-drug police dogs have high accuracy and sensitivity, and are currently the most important way of animal anti-drug detection, but they require full-time trainers, the training costs are expensive, and the training period is long, and the drug detection can only be performed by the trainer through the behavior of the dog make rough judgments
