Embodiment Construction

[0049] The present invention will be further described below according to accompanying drawing:

[0050] The invention provides a virtual-axis millimeter-wave human body security inspection system, which includes a virtual-axis track unit, a scanning unit, a scanning drive unit, a processing unit and a display unit. The security inspection system of the present invention can use a single module or a double module to scan according to actual needs.

[0051] When a single module scans, the virtual axis guide rail unit includes a first arc-shaped guide rail 6, and the outer circumference of the first arc-shaped guide rail 6 has transmission teeth; the scanning unit includes a first group of millimeter-wave antenna arrays 2 and The first millimeter-wave transceiver 3; the scanning drive unit includes a first power unit 5, which is engaged with the outer circumference transmission teeth of the first arc-shaped guide rail 6 through meshing gears, and the first millimeter-wave antenn...

Abstract

The invention relates to a virtual-axis millimeter-wave human body security check system. The system comprises a virtual-axis guide rail unit, a scanning unit, a scanning driving unit, a data processing unit and a display unit, wherein the virtual-axis guide rail unit comprises a first circular-arc-shaped guide rail; the scanning unit comprises a first group of millimeter-wave antenna arrays and a first millimeter-wave transceiver; the scanning driving unit is used for driving the first group of millimeter-wave antenna arrays to scan in a reciprocating virtual-axis circular-arc-shaped locus on the first circular-arc-shaped guide rail; the data processing unit is used for processing a detection signal from the scanning unit to form a human body image to be detected; the display unit is used for displaying the at least one human body image to be detected. In the human body security check system disclosed by the invention, a virtual-axis scanning way is used, the motion load does not need to be reduced, and the rotational inertia is reduced, so that the scanning speed is increased. The system is small in occupied space, and a single / double-module security check system can be assembled more flexibly according to the size of a practical space and the checked amount.

Description

technical field [0001] The invention relates to a human body security inspection system, in particular to a virtual axis millimeter wave human body security inspection system. Background technique [0002] Changes in the form of international anti-terrorism have put forward new requirements for human security inspection in many aspects. First, the security inspection system that can realize the non-undressing three-dimensional holographic imaging detection of objects covered by human clothing has been paid more and more attention; Realize the detection of metal and non-metallic items, including guns, knives, explosives, drugs, CDs, cash, liquids, chips, ceramics, etc.; third, it is necessary to reduce the hazards of the detection methods of the security inspection system to human health on the basis of ensuring the above requirements ; Fourth, products with low cost, strong adaptability, and good user experience will be favored by the market. [0003] The existing technical...
