It retouches imaging detector gate and has the advantages such as safe and reliable, high-resolution, but hardware cost is excessively high and there are potential electromagnetic radiation is simultaneous
Capacitive problem limits its large-scale promotion application.For this problem, passive type Terahertz is had developed both at home and abroad and is scanned into
As detector gate, the THz wave of external radiation is imaged using human body itself, is real imaging technique safe to the human body, it is pregnant
Woman is frequent using also there is no problem with children, and for the security staff of Long Term Contact rays safety detection apparatus itself without accumulative wound
Evil.
Passive type Terahertz scanning imagery detector gate is treated using focal plane imaging system by two-dimensional scan realization
The non-formula safety detection of undressing of inspection personnel, such system usually have two passive type Terahertz scanning imagery scanner opposite directions to put
It sets.When the system is operating, personnel to be tested enters scanning area, the motionless state of remains stationary, and two passive type Terahertzs are scanned into
The front to personnel to be tested and back side progress two-dimensional scan as scanner, after scanned, personnel to be tested walks out of scanning area, complete
At safety check flow.Existing passive type Terahertz scanning imagery detector gate, in order to reduce cost, scanner is visited usually using single
Device is surveyed, using two-dimentional machinery scanning imagery, image taking speed is slower, and maximum safety check speed only has about 400-600 people/hour, safety check
The too low application range for limiting this technology of speed.For this problem, it is also proposed passive type Terahertz array both at home and abroad
Scanning imagery detector gate model machine forms array to improve image taking speed by multiple detectors, but cost significantly rises, market
It is difficult to receive.
Utility model content
Purpose of the utility model is to solve the defects that safety check image taking speed in the prior art is slow, provide a kind of automatic
Pavement formula passive type terahertz imaging safe examination system solves the above problems.
To achieve the goals above, the technical solution of the utility model is as follows：
A kind of moving sidewalk formula passive type terahertz imaging safe examination system, including it is passive type Terahertz scanner, automatic
Pavement and automatic hand rail；It at least is vertically arranged with the passive type Terahertz scanner in the side of moving sidewalk, to
To the body scans detection on moving sidewalk；The automatic hand rail is arranged above moving sidewalk, is gripped for human hand；
The moving sidewalk includes transmission crawler belt；It is arranged at intervals on the crawler belt multigroup for limiting tested personnel
The limit of foot identifies；Tested personnel stand when being moved to before passive type Terahertz scanner after limit mark is upper, front or
The back side is against the passive type Terahertz scanner.
Preferably, it is respectively arranged with the passive type Terahertz scanner in the both sides of moving sidewalk.
Preferably, it is each configured with waiting pedal at the entrance and exit of the moving sidewalk；The waiting pedal exists
Region in addition to the side set foot on the side of pedal for tested personnel and be connected with the entrance of moving sidewalk or outlet is equal
It is provided with fence.
Preferably, the automatic hand rail includes running track and at least two handgrip being fixed thereon；Institute
It is loop configuration to state running track, wherein one section is flat segments；The flat segments are arranged along the moving sidewalk traffic direction
And in its top；The running track is synchronous with the speed of service of moving sidewalk.
Preferably, which further includes monitoring client；The passive type Terahertz scanner is connect by network with monitoring client；
Equipped with matched A/D acquisitions, imaging machine in the passive type Terahertz scanner；The imaging machine testing,
The dangerous material carried in identification, the positioning person, and send testing result information and warning reminding to monitoring client.
The utility model compared with prior art, has the advantages that：
The utility model is continuous continual to personnel to be tested's progress safety check scanning imagery, significantly improves safety check speed
Degree, maximum safety check speed can be more than 1000 people/hour.
The THz wave of external radiation is imaged using human body itself, is the human body imaging technique being perfectly safe.
Passive type Terahertz scanner only does the scanning of One-dimensional Vertical direction, and simple detector may be used and add one-dimensional mechanical scanning
It realizes, technically realize fairly simple, hardware cost is relatively low, is easy to be received by market.
