Abstract

The invention relates to a passing through type metal probe system that includes signal process circuit, CPU, oscillating circuit and coil assembly that includes emitting coil and receiving coil. The invention could equally probe magnetic field and has good anti electromagnetic interference ability. It could determine the approximate location of the metal object.

Description

【Technical Field】 [0001] The invention relates to a metal detection system, in particular to an intelligent through-type metal detection system. 【Background technique】 [0002] The main function of the pass-through metal detection system is to accurately detect hidden prohibited metal objects (such as firearms and knives carried by individuals). In recent years, the pass-through metal detection system has been widely used in public places such as airports, schools, courts, stadiums, railway stations, passenger terminals, etc. During the security inspection process, the pass-through metal detection system has become a necessary equipment. [0003] For the detection of prohibited metal objects, the operation of the existing pass-through detection system has at least four defects: First, in the pass-through detection system, the original detection magnetic field generated by the transmitter-receiver coil has a working blind spot. Carrying prohibited metal objects through these blind...
