Non-Destructive Testing Method And System For Goods Such As Trucks, Container Trucks, And Railway Carriages

The present invention includes a method and scanning system for non-invasive inspection of vehicles, container trucks and rail cars. Inspection can be accomplished without direct human intervention in the subject being inspected, eliminating time-wasting activities such as physical control, unpacking, etc. The proposed method of non-intrusive inspection of vehicles and containers has a high detection capacity (up to 200 vehicles per hour) by implementing a full vehicle radiography (except the cab) while driving through the scanning entrance and constructing a A system of methods that is geometrically optimized so that it can be quickly transported in ISO standardized containers using conventional transport systems (aircraft, ship, train, rail, rail, or on the ground on public roads) where a high degree of safety is required area. The system implementing the above method consists of a mobile scanning unit mounted on a chassis equipped with a boom that displays a detector area specially selected according to the type of penetrant radiation used. In transport mode, the boom is folded to ensure a minimum gauge, allowing the vehicle to conform to the authorized dimensions for public road transport, or to fit the system into an ISO high-cube standardized container. At the end of the "U" probe, scan parallel to the "U" probe. The scanning system also includes a mobile control center, located outside the quarantine area a, whose role is to remotely control all processes involved in the non-invasive inspection. The mobile control center includes acquisition, processing, storage and image display subsystems. The scanning system includes a perimeter protection subsystem and an automatic traffic management subsystem.

Non-destructive testing method and system for goods such as trucks, container trucks, and railway carriages

The present invention includes a method and system for non-invasive inspection of vehicles, container trucks and rail cars. Inspections can be performed without direct human intervention on the inspected object, eliminating time-consuming activities such as actual physical control, unpacking, etc.

Using the present invention, a radiographic image of the object under inspection is achieved on which a specially trained operator can assess the quantity and nature of the cargo loaded onto the scanned object. Through the analysis of radiographic images, exploratory detection of contraband can be realized, illegal transportation of contraband or undeclared products (such as drugs, explosives, weapons, etc.) Entry and exit of inspected vehicles are protected against terrorism, for example: airports, sea and river ports, border crossings, conflict zones or military bases.
 

For non-invasive control, several scanning methods are known, in which the following radiation sources are used:

• Sources of gamma radiation naturally produced by encapsulated radioactive materials (eg cobalt, cesium, etc.). ;

• X-ray, gamma or neutron linear accelerators.

  The principle of non-intrusive detection systems is to place an array of detectors linearly in front of the penetrating radiation beam, creating a radiation tunnel that moves relative to the object being scanned. The electrical signals from the detector are analog/digital processed to generate line-by-line radiographs and display them on the PC screen. The reception and processing of signals generated by a large number of detectors (often hundreds) means a complex network of electronic blocks and wires, with numerous parallel connections between the boom and the subsystems that produce the radiographic images.

The relative movement between the scanning object and the scanning system is accomplished by moving the moving object through the stationary scanner or moving the moving scanner around the stationary object.

The entire process of operating these systems is done in a control cabin on the scanning system, which requires extensive radiation shielding. This method exposes the shortcomings of the operator's professional radiation exposure.
