Abstract

The invention belongs to the technical field of security inspection systems, and particularly relates to a single-channel unattended security inspection system control circuit. The single-channel unattended security inspection system control circuit comprises a DC12V power supply, wherein the positive electrode of the DC12V power supply is connected to a pin 4 of a photoelectric coupler IC2, a relay J2, a pin 4 of a photoelectric coupler IC3, a relay J3, a pin 4 of a photoelectric coupler IC1, a relay J1, a resistor R16, a collector electrode of a triode Q10 and a relay connected to a relay J4through a KA 1; a pin 2 of the photoelectric coupler IC2 is grounded, a pin 1 of the photoelectric coupler IC2 is connected to an A2 end through a resistor R3, a pin 3 of the photoelectric coupler IC2 is connected to a resistor R41, the other end of the resistor R41 is connected to a collector electrode of a triode Q6 and a base electrode of a triode Q4, an emitter electrode of the triode Q6 is grounded, and a base electrode of the triode Q6 is connected to a resistor R4; and an emitter electrode of the triode Q4 is grounded, and a collector electrode of the triode Q4 is connected to the relay J2. The single-channel unattended security inspection system control circuit provided by the invention realizes a working process of one-way unattended security inspection, and can be matched with amonitoring camera combination to realize completely unmanned security inspection channel management.

Description

technical field [0001] The invention belongs to the technical field of security inspection systems, and in particular relates to a single-channel unattended security inspection system control circuit. Background technique [0002] In the prior art, in order to realize the confidentiality of the production workshop and the safety of precious metal items, a security inspection channel is often set up at the exit of the production workshop to prevent employees from taking out confidential materials or precious metal items from the production workshop. However, the reliability of the existing security inspection channels is not enough, and it is often necessary to arrange personnel on duty to cooperate with the inspection. Contents of the invention [0003] The purpose of the present invention is to provide a single-channel unattended security inspection system control circuit. [0004] In order to achieve the above object, the present invention adopts the following technical...
