Embodiment 1

[0051]In Embodiment 1 of the present invention, a personnel safety inspection system 100 is provided, including: a channel 110, the channel 110 provides an inspection space isolated or partially isolated from the surrounding environment, and at least one The sub-channels are for the inspected person 102 to pass through, and at least one millimeter-wave imaging device 120 is provided for each of the sub-channels to perform millimeter-wave imaging on the inspected person 102; and an ion mobility spectrometer 130 is used to image the inspected person The particle or gas emitted or volatilized by the inspector 102 into the air in the channel 110 is ionized, and then its migration rate under the action of an electric field is measured to identify the substance.

[0052] The personnel security inspection system 100 also includes a console 150 for controlling the work of at least one millimeter-wave imaging device 120 and the ion mobility spectrometer 130 , and receiving data from the...

Embodiment 2

[0070] On the basis of Embodiment 1, another millimeter-wave imaging device (not shown in the figure) is installed on both sides of the subject to monitor and measure both sides of the subject.

Embodiment 3

[0072] Similar to Embodiment 1, but the millimeter wave imaging device 120 is modified into four millimeter wave imaging devices. If the moving direction A of the person is taken as the x direction, and the midpoint of the measurement line or the midpoint of the measurement region (ie the center point of the region) 117 is taken as the origin, a coordinate system is established on the ground plane. Then, a millimeter-wave imaging device 120 is respectively installed in directions of about 45 degrees, 135 degrees, 225 degrees, and 315 degrees, and its aperture faces are all facing the vertical line passing through the origin of coordinates, and its top view is as follows figure 2 shown. The feature of Embodiment 3 is that the millimeter wave imaging device 120 inspects the inspected person from four angles of view, the millimeter wave imaging device 120 can be placed upright, and the person can go straight without resistance.

Abstract

A person safety inspection system includes a passage and an ion migration spectrometer, wherein the passage provides an inspection space totally or partially isolated from the surrounding environment, and at least one sub-passage for a to-be-inspected person to pass is arranged in the inspection space; the ion migration spectrometer is used for ionizing the matter particulate or gas emitted or evaporated from the to-be-inspected person into the atmosphere in the passage, and measuring the migration rate thereof under the electric field action, so as to facilitate matter identification. Furthermore, at least a device for inspecting radioactive matter is arranged in the passage for inspecting whether the to-be-inspected person is with the radioactive matter. Each device for inspecting the radioactive matter is used for inspecting one or multiple sub-passages.

Description

[0001] This divisional application is a divisional application of a Chinese invention patent application with an application date of June 27, 2008, titled "A Personnel Safety Inspection System", and application number 200810115792.1. technical field [0002] The invention relates to the field of safety inspection, in particular to a corridor-type safety inspection system for continuous and automatic safety inspection of personnel (including their carry-on items). Background technique [0003] Security inspection technology and equipment are widely used in airports, railway stations, ports, customs and other important places that require security inspections. They are used to perform body inspections, luggage inspections, bulk cargo and container inspections, etc., mainly to detect explosives, drugs and metal weapons. [0004] A common technology for continuous, automated security screening of personnel is security screening gates. The safety inspection door adopts pulsed ma...
