The invention discloses an integrated security inspection system, comprising: a server, an information input unit in an information input area, a tray distributing and associating unit and a security inspection imaging and sorting unit in a baggage check area. The tray distributing and associating unit distributes a tray with an identifier to a piece of baggage. The information input unit obtains and sends information of a person to the server. The tray distributing and associating unit obtains and sends information of the person and the identifier of the tray to the server, which processes them to generate a first association information. The security inspection imaging and sorting unit checks the baggage to obtain a security image, read the identifier, and send them to the server, which processes them to generate a second association information. The server matches and stores the information of the person with information of the security image.

X-ray scanning methods and systems are provided in embodiments of the present inventions. According to one illustrative implementation, an exemplary method may comprise: collecting background data when no X-ray is emitted; collecting air data when X-rays are emitted and there is no object to be scanned in an inspection channel; scanning an object to collect original scanning data; and preprocessing the original scanning data according to the background data and the air data to acquire scanned image data. In some embodiments, when performing an X-ray scanning of a static object, implementations may measure the background data and the air data and process the scanning data, thereby solving noise issues caused by mechanical vibration and thus improving the measurement accuracy.

Disclosed is a relocatable vehicle inspection system. The relocatable vehicle inspection system includes a radiation source for radiating radials; a detection array for receiving the radials from the radiation source, so that an image of the cargo on the vehicle to be inspected may be obtained; a moving device on which the radiation source and the detection array are disposed; and a ramp-platform device. The ramp-platform device includes first and second intermediate parts (); first, second, third and fourth ramp parts (); first, second, third and fourth transitional parts (). The first and second transitional parts can be foldably or removably connected to the first intermediate part, and the third and fourth transitional parts can be foldably or removably connected to the second intermediate part. The said ramp-platform device can be placed onto or removed away from the moving device under disassembling and folding conditions.

On-board relocatable vehicle inspection system having ramp-platform device

Disclosed is a ramp-platform device for an on-board relocatable small vehicle inspection system. The ramp-platform device includes a connection frame having a rectangular shape and defining therein an inner space, first and second intermediate parts which are disposed in parallel with each other and at two opposite sides of the connection frame, first to fourth ramp parts having a substantially triangle shaped longitudinal section. The first and second ramp parts are removably connected to the two opposite ends of the first intermediate part separately, and the third and fourth ramp parts are removably connected to the two opposite ends of the second intermediate part separately. The height of a top end of the first to the fourth ramp parts is substantially equal to the height of the first and second intermediate parts. When it is not in use, the ramp-platform device may be placed on the scanning vehicle of the moving device in a disassembling and folding conditions, and when it is under inspection, the vehicle to be inspected is raised to a predetermined height by assembling and spreading the ramp-platform device, so that a chassis and wheels of the small vehicle may be entered into the scanning range to achieve the inspection of each part of the small vehicle.
