Embodiment 1

[0052] Such as figure 1 As shown, the present embodiment provides a fast-scanning planar millimeter-wave human body security inspection device, including: A panel 1 base 3 and a display device 4, A panel 1 is fixed on one side of the base 3, and is used to monitor the human body 10 standing on the base For millimeter-wave imaging security inspection, the base 3 is also integrated with a foot metal detection device 3' for detecting metal objects on the bottom of the human body; the display device 4 is placed outside the A panel 1 for human-computer interaction, equipment control and result display.

[0053] Such as Figure 4 As shown, panel A 1 includes an H millimeter wave transceiver array 7, an L millimeter wave transceiver array 8, a millimeter wave transceiver device 21, a transmission device 9, a drive device 13, a signal acquisition device 20, an intelligent computing device 19, and a stance judging device 26 . The driving device 13 provides the driving force, and the ...

Embodiment 2

[0063] In this embodiment, on the basis of Embodiment 1, the H millimeter wave transceiver array 7 and the L millimeter wave transceiver array 8 work in a separate transceiver mode, and the transceiver separate mode means that the L millimeter wave transceiver array 8 receives the H millimeter wave transceiver array 7 The transmitted millimeter wave signal echo signal, the H millimeter wave transceiver array 7 receives the millimeter wave signal echo signal transmitted by the L millimeter wave transceiver array 8, and the millimeter wave transmission path is as follows Figure 6 As shown in 12, the advantage of this is to increase the observable angle and improve the problem of weak echo signals caused by the flicker effect of active millimeter wave imaging on the side of the human body, chest and other parts, thereby enhancing the overall detection rate.

Embodiment 3

[0065] In this implementation, on the basis of Embodiment 1, there is no soft or rigid connection between the millimeter-wave transceiver arrays in A panel 1 and B panel 2, which makes A panel 1 work alone ( figure 1 ), can also work in conjunction with B panel 2 ( figure 2 ).

[0066] Such as Figure 3-5 As shown, the B panel 2 includes the H millimeter wave transceiver array 7, the L millimeter wave transceiver array 8, the transmission device 9, and the drive device 13, and shares the millimeter wave transceiver device 21, the signal acquisition device 20, the intelligent computing device 19 to reduce costs.

[0067]When A-panel 1 and B-panel 2 work together, after the human body stands on the base, and after the human body stands on the base 3, the stance judging device 26 judges that the human body is standing stably, and then sends a start security check signal to the intelligent computing device 19, and the intelligent computing device 19 controls The sole metal det...

Abstract

The invention relates to the technical field of security check, in particular to a plane millimeter wave human body security check device and method capable of achieving rapid scanning, the plane millimeter wave human body security check device comprises a panel, a base and a display device, a sole metal detection device is integrated in the base, and the display device is arranged outside the panel. The panel comprises an H millimeter wave receiving and transmitting array, an L millimeter wave receiving and transmitting array, a millimeter wave receiving and transmitting device, a transmission device, a driving device, a signal acquisition device and an intelligent operation device; and according to the plane millimeter wave human body security inspection equipment capable of rapidly scanning, the problems that the existing plane millimeter wave human body security inspection equipment is low in security inspection efficiency, low in security inspection reliability and inflexible in use form are solved.

Description

technical field [0001] The invention relates to the technical field of security inspection, in particular to a fast-scanning planar millimeter-wave human body security inspection device and method. Background technique [0002] Traditional human security inspection equipment mainly includes metal security gates, metal detectors, X-ray human body security inspection instruments, etc. Specifically, metal security doors and metal detectors can only detect metal objects. X-ray human body security inspection equipment cannot be applied to large-scale general human body inspection due to the certain hazards of X-ray photoionizing radiation to human health. In order to make up for the shortcomings of traditional security inspection methods, millimeter-wave imaging technology has made great progress in the application of human body security inspection in recent years. The millimeter-wave human body security inspection equipment has the characteristics of being able to penetrate hum...
