Description

Detection Systems

technical field

The utility model relates to a detection system, in particular to a mobile detection system.

Background technique

In the prior art, since the beginning of the 1990s, drag-type container inspection systems have come out, such as the large-scale container inspection systems produced by German Heymann and British Aerospace Corporation. They are installed in a radiation-shielding inspection channel, equipped with a fixed radiation source that can generate high-energy X-rays and an array detector that can receive X-rays passing through the container. The container vehicle is dragged through the inspection channel. This inspection system is very large, covering an area equivalent to a football field. It has the disadvantages of large area occupied by civil engineering, high cost of system engineering, difficult maintenance, and inability to realize random inspection in different places. For this reason, some manufacturers at home and abroad have developed various forms of vehicle-mounted mobile container inspection equipment. The inventor of the utility model discloses a utility model titled "Two-vehicle Mobile Detection System Using Accelerator as a Radiation Source" (CN129524), which includes an accelerator, a scanning vehicle and a control vehicle. Its characteristics are: a rotatable tray is installed on the bracket of the scanning car, and an electron linear accelerator, a collimator for X-ray shielding, and a vertical support (called "vertical support" in the original text) are installed on the tray. ), a gantry formed by a horizontal cantilever equipped with detectors and a vertical cantilever. During detection, the control vehicle stays away from the detection site and controls the gantry to cross the container in parallel. The utility model has the characteristics of fast detection speed, clear imaging graphics, and no harm to the human body. However, in the detection system, the detection equipment is installed on the automobile chassis, and the scanning process is realized by the movement of the system chassis during scanning.

Compared with the existing vehicle-mounted detection system, since the detection equipment of the present invention can be detachably installed on the semi-trailer through the auxiliary frame, rapid assembly can be realized, and the semi-trailer of the present invention is free of any The drive source is driven by the trailer, so the overall system cost is low.

Another important advantage of the utility model is that: since the semi-trailer itself has no driving source, it can be connected with any type of tractor. For example, in European countries with high exhaust emission standards, local tractors can be used to connect with the semi-trailer, so It will not be restricted by emission regulations, thereby greatly expanding the application range of the detection system of the present application. However, the existing vehicle-mounted detection system cannot do this, because the entire detection equipment is directly installed on the chassis of a special-purpose trailer with an independent driving source.
