Abstract

The embodiment of the invention provides an article detection system. The system comprises at least one group of sensors, wherein one group of sensors is used for detecting an article carried by a moving body in one direction, and each group of sensors is arranged on at least one side of the advancing direction of the moving body and transmits signals to the space. The system further comprises a determining unit used for determining the azimuth angle to be deployed of the first sensor in each group of sensors according to a preset effective detection area, and an acquisition unit which is usedfor acquiring a reflection signal received by each group of sensors deployed according to the azimuth angle, wherein the reflection signal is a reflection signal obtained after the transmitted signals are reflected by the moving body; the system further comprises a detection unit which is used for extracting the characteristics of the article carried by the moving body according to the reflection signal and determining the type of the article according to the characteristics. Therefore, the method is not limited by a detection scene, and the to-be-detected article carried by the moving bodyin each direction can be detected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an object detection system. Background technique [0002] In recent years, people have paid more and more attention to the safety of public places, and how to detect dangerous goods such as controlled appliances and flammable and explosive materials has become an important issue. At present, detection devices for dangerous goods are widely used in airports, railway stations, subway stations, stadiums and other crowded places. Dangerous goods detection devices can be divided into two types: contact type and non-contact type. The contact detection device needs to place suspicious items (such as bottles containing liquid) on the detection device for detection, while the non-contact detection device can start the detection and distinguish whether the suspicious object moves within a certain range of the detection device. Belong to dangerous goods. [0003] At present, one of...
