An environment control system for a terahertz human body security detector

Abstract

The embodiment of the invention provides and relates to an environment control system for a terahertz human body scanner. The environment control system for the terahertz human body scanner comprisesa security check cabin, a refrigeration system and a ventilation circulatory system; the security check cabin comprises an equipment room and a security check channel; the equipment room is located onat least one side of the security check channel and used for containing the terahertz human body scanner; the security check channel is used for checked personnel to pass through; the refrigeration system is installed on the equipment room and used for adjusting and controlling the environment temperature and environment humidity of the equipment room; and the ventilation circulatory system is installed at the communicating portion of the security check channel and the equipment room, and used for driving air of the equipment room and the security check channel to circulate. The environment control system for the terahertz human body scanner solves the problem that interference factors like electromagnetic waves and temperature in the environment where existing terahertz human body scanners are located cause poor imaging definition of the terahertz human body scanners.

Description

technical field [0001] The invention relates to the field of security inspection, in particular to an environment control system for a terahertz human body security inspection instrument. Background technique [0002] At present, most of the security inspection equipment in airports, railways, etc. are composed of X-ray systems or CT detection systems. The high radiation of these equipment will harm the human body and cannot be used for human security inspection. Metal security doors can only alarm but not locate. Non-metallic contraband is powerless, and hand-held metal detectors cannot detect non-metallic contraband, and must be operated by contact. The detection speed is slow, and it is easy to cause the inspected person to feel violated. The appearance of the terahertz human body security detector solves the above problems. The terahertz human body security detector is imaged by passively receiving the electromagnetic waves in the terahertz band of the measured object, s...
