Problems solved by technology

The former dragging method will add the image of dragging the flat panel to the image, and it is necessary to drag the flat panel back for the next inspection, and the inspection efficiency is not high; the latter dragging method has to go through the detection system, so dragging The driving system needs to be docked on both sides of the detection system, and the structure is complex. In addition, the driving system is stable and reliable due to the weight change of the vehicle under inspection.

Embodiment 1

[0028] figure 1 , figure 2 , image 3 and Figure 4 The vehicle self-propelled scanning system for fixed transmission radiation imaging includes: a fixed transmission detection system, specifically, the fixed transmission detection system includes a frame-shaped scanning device 1 and an imaging device, and the scanning device 1 is fixed on the ground foundation 2, the vehicle passes through the scanning device 1, and a perspective image of the vehicle is formed on the imaging device.

[0029] On the vehicle entry side of the transmission detection system, more specifically, a ramp 3 is set on the vehicle entry side of the scanning device 1, the ramp 3 is movable, and the end of the ramp 3 close to the scanning device 1 passes through the hinge shaft 4 Hinged on the ground foundation 2, the opposite end of the ramp 3 can rotate up and down around the hinge shaft 4, thereby changing the inclination angle of the ramp 3 relative to the horizontal plane. A hydraulic cylinder 6 ...

Embodiment 2

[0035] Figure 5 The second embodiment of the present invention shown has basically the same structure as that of Embodiment 1, the difference is that the wheel track is a single-side wheel guide groove 5', and the single-side wheel guide groove 5' is only on the vehicle side. The guide groove is set under the side wheel, and the section structure of the guide rail groove 5' on one side wheel is referred to Figure 4 .

Embodiment 3

[0037] Figure 6 The third embodiment of the present invention shown is basically the same structure as Embodiment 1, except that the wheel track is a vehicle guide rail groove 5'', and the groove width of the vehicle guide rail groove 5'' is 1.2-2 times the width of the vehicle, the slot height ranges from 3cm-20cm, and its cross-sectional structure refers to Figure 4 .

Abstract

The invention discloses a vehicle automatic dragging scanning system supportive of fixed transmission radiation imaging. The system comprises a fixed transmission detection system, an oblique ramp is arranged on a vehicle incoming side of the transmission detection system, and a vehicle release device is arranged on the ramp. A vehicle automatically slides along the oblique ramp under action of gravity, and the vehicle is enabled to pass the transmission detection system at a preset speed to complete detection by controlling oblique angle and / or sliding length. By using the vehicle automatic dragging scanning system, the circumstance that a driver is exposed to radiation illumination due to being detected along with the vehicle is avoided, passing efficiency is high, and equipment maintenance is convenient and quick.

Description

technical field [0001] The invention relates to the field of digital radiation scanning imaging, in particular to a vehicle self-dragging scanning system for fixed transmission radiation imaging. Background technique [0002] In order to combat smuggling and anti-terrorism activities and security inspections, it is necessary to strengthen the security inspections of freight vehicles, small vehicles, and cargo luggage, such as luggage security inspection systems, large container / vehicle security inspection systems, small vehicle security inspection systems and other inspection equipment. [0003] The above-mentioned detection systems are all based on the principle of ray transmission imaging, and the system includes a ray source device, an array detector system, a drag scanning system, and an image display and analysis system. The rays emitted by the ray source are collimated into a sheet-like ray beam. The rays pass through the object to be inspected and then enter the array...
