Green channel vehicle detector for inversely scattering X-ray

Abstract

The invention discloses a green channel vehicle detector for inversely scattering an X-ray. The green channel vehicle detector is characterized by comprising a shielding cylinder, a servo motor, an X-ray beam collimator, an X-ray tube and an X-ray solid receiver, wherein the servo motor drives the shielding cylinder to rotate; the X-ray beam collimator is arranged on the circumference of the shielding cylinder; the X-ray tube is arranged at the axis of the shielding cylinder and is still; the X-ray solid receiver is arranged at the outlet end of the shielding cylinder; the green channel vehicle detector also comprises high-voltage power supply equipment for providing high-voltage electricity to the X-ray tube, a cooling system for cooling the X-ray tube, and a data collecting and displaying system for processing the signal transmitted from the X-ray solid receiver. The green channel vehicle detector has the beneficial effects that an X-ray source is taken as a detection source, the green channel vehicle detector is more significant in effect on differentiation of an organic matter and an inorganic matter, an X-ray source with low-medium energy is used, and the green channel vehicle detector is low in demands on shielding, simplified in equipment structure, small in volume, light in weight, and easy to install and move.

Description

technical field [0001] The invention relates to a vehicle detector, in particular to an X-ray backscattering green channel vehicle detector, which belongs to the technical field of vehicle non-destructive testing equipment. Background technique [0002] In recent years, with the implementation of the national policy of establishing a green channel for fresh and live agricultural and sideline products on expressways, local governments have also provided corresponding policies for reducing fees. However, some criminals take advantage of this policy to evade the state's tolls by means of mixed loading, false certificates, overrunning, overloading and other means, causing great economic losses to the expressway. Therefore, the detector of the green channel vehicle came into being. [0003] X-ray backscattering green channel vehicle detector, which shoots X-rays on the object, then measures and processes the backscattered information, and then calculates the image and informatio...

Problems solved by technology

[0004] The ray source of the X-ray backscattering green channel vehicle detector uses medium and low-energy X-rays for scanning. Foreign AS&E companies cooperate with domestic Tsinghua Tongfang Nuctech to use accelerators, and also use flying point scanning solutions. A Ministry of Public Security also The same technology is being developed, but the energy is high, the cost is high, the equipment is bulky, and it is difficult to move once installed
