Abstract: This invention relates to a movable divided inspection system and method, wherein the scanning inspection system comprises a first radiation source, a first detection means, a first automated guided vehicle and a second automated guided vehicle. The first radiation source is mounted on the first automated guided vehicle. The first detection means is mounted on the second automated guided vehicle. The first automated guided vehicle and the second automated guided vehicle are able to drive the first radiation source and the first detection means to a preset scan inspection position, so as to form a scanning passage for passage of an article to be scanned between the first and second automated guided vehicle, such that scanning inspection of said article to be scanned is realized by relative movement of said article to be scanned with reference to said first automated guided vehicle and said second automated guided vehicle.

Abstract: The present invention discloses a dual-energy ray scanning system, scanning method and inspecting system and relates to the radiation scanning, imaging and detecting field. The dual-energy ray scanning system comprises a ray source for alternately emitting a high energy ray and a low energy ray; a filter comprising a low energy filtering element and a low energy transmitting element; and a control device for controlling said ray source and said filter to make said low energy filtering element of said filter be aligned with a beam exit direction of said ray source when said ray source emits a high energy ray so as to filter low energy portion of said high energy ray out and transmit high energy portion of said high energy ray out, and for controlling said ray source and said filter to make said low energy transmitting element of said filter be aligned with said beam exit direction of said ray source when said ray source emits the low energy ray so as to transmit said low energy ray out. This not only can improve transmissivity of the high energy ray, but also does not lose the spatial wire resolution of the low energy ray, and this guarantees the index of transmissivity and the index of spatial wire resolution at the same time, such that the dual-energy ray can sufficiently utilize a difference in its penetration characteristics to recognize the object to be inspected, thereby reaching the objective of security inspection.

Abstract: A vehicle inspection system is described. The vehicle inspection system comprises: an inspection device, for performing an inspection on a vehicle to be inspected; a carrier platform, for carrying the vehicle to be inspected; and an unmanned controlled travelling device for moving the carrier platform to pass through a scanning area of the inspection device, so as to perform the inspection on the vehicle to be inspected. In the present disclosure, the vehicle to be inspected is carried by the carrier platform, and the unmanned controlled travelling device is used to move the carrier platform to pass through the scanning area of the inspection device, so that the vehicle to be inspected can be subject to inspection smoothly. There is no driver required to drive through the scanning area in this process, thus avoiding exposure of a driver to a threat of radiation.
