Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] see figure 1 , an embodiment provides a terahertz self-feedback system 1000 for atmospheric high-risk chemical detection, the device includes:

[0032] A detection device 100, the detection device 100 is used to detect information of high-risk chemicals in the atmosphere.

[0033] Specifically, the detection device 100 is a device for sampling high-risk chemicals in the atmosphere and obtaining terahertz characteristics of high-risk chemicals in the atmosphere. The information on high-risk chemicals in the atmosphere specifically includes information on the concentration of high-risk chemic...

Abstract

The invention relates to a terahertz self-feedback system for detecting hazardous chemicals in atmosphere. The system comprises a detection device, a mechanical adjusting device, a processor and a movable carrying device; the detection device is used for detecting kind and concentration information of hazardous chemicals in atmosphere; the mechanical adjusting device is used for adjusting positionof the detection device; the processer is used for processing kind and concentration information of the hazardous chemicals in atmosphere which are detected by the detection device, and controlling the mechanical adjusting device and the movable carrying device, and the movable carrying device is used for carrying movement of the hazardous chemicals in atmosphere of the system for detecting hazardous chemicals in atmosphere in a space; one end of the mechanical adjusting device is connected to the carrying device, and the other end is connected to the detection device. The self-feedback system has the advantages of high adjustability of detection positions, high intentionality of detection space coordinates, and low repetition rate.

Description

technical field [0001] The invention relates to the field of environmental safety, in particular to a terahertz self-feedback system for detecting atmospheric high-risk chemicals. Background technique [0002] With the increasingly severe non-traditional security threats and the rapid development of the chemical industry, all countries in the world are facing increasingly serious threats of chemical poison terrorist attacks and high-risk chemical industry leakage accidents, such as the sarin gas attack in Tokyo, Japan and Tianjin, my country. Hong Kong 8.12 explosion accident. In the face of high-risk chemical explosions or terrorist attacks, the spatial distribution and dynamic process detection of atmospheric high-risk chemicals are often the key to emergency response, and so far are still international frontier hot spots and technical problems. [0003] Traditional detection methods are often fixed detection methods, such as airport security inspection devices, or manual ...
