Abstract

The invention relates to a security check system, a data acquisition rate adjusting method and an article information detection method. The security check system comprises a first detection device, a second detection device, a security check device and a conveyor belt; the first detection device is used for detecting a to-be-detected object moving to a first detection position and generating a first detection signal of the to-be-detected object; the second detection device is used for detecting the to-be-detected object moving to a second detection position and generating a second detection signal of the to-be-detected object; the security check device is used for determining the actual conveying speed of the conveying belt according to the time interval between the received first detection signal and the received second detection signal and the conveying distance between the first detection position and the second detection position. According to the invention, active detection of the security check device on the actual conveying speed of the conveying belt is realized, so that the timeliness rate of adjusting parameters according to the actual conveying speed in the security check device is improved, and the accuracy of scanning imaging of an object to be detected in the security check device is further improved.

Description

technical field [0001] The application relates to the technical field of security inspection machines, in particular to a security inspection system, a data collection rate adjustment method and an item information detection method. Background technique [0002] In the fields of logistics transportation, subway security inspection, etc., security inspection machines are widely used in the detection of item information of luggage and parcels. By detecting the item information inside suitcases, handbags, and parcels, it can be judged whether prohibited items are included, thereby improving logistics transportation and security. The safety of traffic travel. The security inspection machine is mainly set up on the conveyor belt, and scans and identifies the object to be inspected that is transported to the security inspection machine via the conveyor belt, so as to obtain the item information inside the object to be inspected. In the scanning and identification process, in orde...
