Safety early-warning system

Abstract

The invention discloses a safety early-warning system which comprises an odor acquisition device and a cloud database server. Data transmission of the odor acquisition device and the cloud database server is carried out through a wireless network. The odor acquisition device comprises an odor detection unit, a microprocessing unit, a wireless communication unit and a power supply unit, wherein the odor detection unit is used for acquiring human body odor close to the above odor acquisition device and converting the acquired odor information data to an electric signal which is transmitted to the microprocessing unit; the microprocessing unit is used for controlling the wireless communication unit to send the above converted human body odor information data to the above cloud database server; data transmission between the wireless communication unit and the above cloud database server is carried out through the Internet; human body odor information data of criminals is stored in the cloud database server, and an early warning notice is generated according to a comparison result of the above received human body odor information data and the stored human body odor information data of criminals, thus realizing early warning notification the first time.

Description

technical field [0001] The invention relates to the security field, in particular to a system for realizing safety early warning and notification by using human body odor collection technology. Background technique [0002] With the improvement of living standards, the addition of valuables at home has increased, leading to an increase in theft. Traditional residential anti-theft uses anti-theft windows, anti-theft doors, anti-theft nets, etc., which can effectively prevent criminals from crossing the room to carry out theft. Existing anti-theft devices use infrared probes, which are easily affected by factors such as light and smell, and are prone to false triggering of alarms. Residents cannot timely understand what is happening indoors, and cannot obtain evidence of criminals' crimes, which brings certain difficulties to public security personnel in solving cases. .

Problems solved by technology

Existing anti-theft devices use infrared probes, which are easily affected by factors such as light and smell, and are prone to false triggering of alarms. Residents cannot timely understand what is happening indoors, and cannot obtain evidence of criminals' crimes, which brings certain difficulties to public security personnel in solving cases.

[0003] Secondly, it often happens that the same criminal commits multiple crimes before being solved by the public security personnel. The reason for this problem is that the public security personnel cannot find out the identity information of the criminal, know the whereabouts of the criminal, and cannot arrest the criminal immediately. , although infrared cameras are installed in different areas of each street, after the criminals wear hats or masks and other props, the images taken by the cameras cannot identify the identity of the criminals, so it is impossible to identify the places where criminals often commit crimes or live in seclusion , and the above-mentioned monitoring through infrared cameras requires a large number of public security personnel to supervise the video, so it is easy to miss some criminals' activity information, and it is difficult to bring criminals to justice
