Embodiment 1

[0023] A vehicle safety inspection device, such as figure 1 As shown, it includes a moving chassis 1, a steering mechanism 2, a lobster eye X-ray imaging system 3, a data acquisition board 4, an intelligent controller 5, and a tablet computer; the steering mechanism is fixed at the center position directly above the moving chassis, and the lobster The eye X-ray imaging system is fixed at the end of the steering mechanism, the data acquisition board is electrically connected with the lobster eye X-ray imaging system and fixed at the end of the steering mechanism, and the data acquisition board is electrically connected with the intelligent controller for uploading images Data; the intelligent controller is embedded in the motion chassis, and the tablet computer is wirelessly connected to the intelligent controller for receiving and displaying the data collected by the lobster eye X-ray imaging system through the data acquisition board and processed by the intelligent controller ...

Embodiment 2

[0027] A lobster eye x-ray imaging system such as figure 2 As shown, it includes a low-energy X-ray tube 31, a lobster-eye lens 32, and a scintillation crystal detector 33; the optical axis of the scintillation crystal detector is parallel to the central axis of the field of view of the lobster-eye lens and the central axis of the low-energy X-ray tube;

[0028] The lobster eye lens is as image 3 As shown, it includes a first crystal plate and a second crystal plate arranged crosswise, the first crystal plate is a crystal plate with a sinusoidal cross-section, and the upper end is provided with a first socket distributed in an array, and the second crystal plate It is a crystal slice with a sinusoidal cross section, and the second socket is opened in an array distribution at the lower end, the formula of the sinusoidal curve is y=Asin(x), and the first crystal plate and the second crystal plate are in the same plane , distributed along two mutually perpendicular directions ...

Embodiment 3

[0031] The crystal flakes are loaded with reflective materials. The preparation process of the experimental materials is as follows, and the following materials are all commercially available: tetrabutyl titanate (Ti(CH3CH2CH2CH2O) 4 (TBOT), ≥99.0%); Yttrium oxide (Y 2 o 3 , ≥99.0%); barium fluoride (BaF 2 , ≥99.0%); glacial acetic acid (CH3COOH (HAc), ≥99.5%); acetylacetone (CH 3 C(O)CH 2 C(O)CH 3 , ≥98.0%); anhydrous methanol (CH3OH, ≥99.5%); polyethylene oxide (PEO, Mw~1000,000).

[0032] The poly(titanium diacetate) (PDET) precursor was synthesized by adding HAc (250 g) dropwise to TBOT (643 g) under magnetic stirring in an ice bath for a reaction time of 6 hours until a light yellow powder was obtained. The light yellow powder, oxidized A total of 50g of yttrium and barium fluoride was dissolved in 1000mL of anhydrous methanol at a ratio of 7:4:2. 200g of Hacac was added to the above solution, and then the solution was concentrated into powder again as a precursor of...

Abstract

The invention provides a vehicle safety inspection device, which includes a moving chassis, a steering mechanism, a lobster eye X-ray imaging system, a data acquisition board, an intelligent controller, and a tablet computer; the lobster eye X-ray imaging system includes a low-energy X-ray tube, a lobster eye Eye lens, scintillation crystal detector; the optical axis of the scintillation crystal detector and the central axis of the field of view of the lobster eye lens and the central axis of the low-energy X-ray tube are parallel to each other; the vehicle safety inspection equipment provided by the present invention can detect wheels, Check the bottom of the vehicle, the front engine compartment and the trunk to prevent someone from hiding contraband or dangerous goods in the engine space of the front engine compartment, in the chassis under the vehicle or in the trunk, upgrade to a full-vehicle scanning system, and block The loopholes in the inspection are eliminated, and the inspection is more comprehensive.

Description

technical field [0001] The invention relates to the technical field of safety inspection, in particular to a vehicle safety inspection device. Background technique [0002] The vehicle inspection imaging device is a device used to quickly check whether there are contraband or dangerous goods hidden in the tires or trunk of the vehicle. It is an effective means to combat smuggling and terrorist activities. [0003] At present, the rays used for detection are basically X-rays. The penetrating detection needs to place the light source and the detector on both sides of the target. Relying on the transmitted X-rays to image the target will inevitably cause a certain degree of damage to the human body. harm. The reflective detection is to detect the inverse Compton scattering echo after the X-ray irradiates the target. Its advantages are that it has no harm to the human body and has a long range of action. The X-ray light source and detector can be integrated, which is easy to ca...
