Description

Security check system and sorting method Technical Field The invention relates to the technical field of safety inspection, in particular to a safety inspection system and a sorting method. Background In a large passenger flow security check scene, the security check system is a core system for guaranteeing public security and is used for identifying and sorting out baggage containing suspicious targets, so that the passing efficiency after security check is improved. In the existing security inspection and sorting technology, in order to realize the accurate sorting of suspicious baggage, every piece of baggage needs to be separated in advance, so that misoperation of adjacent baggage caused by sorting action is avoided. Common separation methods include baggage separation by controlling the speed differential of the conveyor belt with a speed governor, baggage separation by using a baggage tray, and the like. However, the two modes have obvious technical defects that in the first speed regulation separation mode, the speed reduction ring can greatly reduce the speed of the whole security inspection process, particularly in large passenger flow scenes such as subways, high-speed rail stations and the like, security inspection ports are extremely easy to be blocked, security inspection efficiency is seriously reduced, in the second luggage tray separation mode, a large number of trays are required to be additionally arranged, the input cost of security inspection equipment is increased, and the transportation, recovery and storage of the trays occupy additional space, meanwhile, the operation complexity of the security inspection process is increased due to the existence of the trays, and the whole efficiency is limited. In order to solve the above problems, it is necessary to design a security inspection system and a sorting method, which can realize accurate partition management and control of objects to be inspected, ensure the sorting efficiency of security inspection equipment in a large passenger flow scene, and effectively reduce equipment investment and labor operation and maintenance cost.
