Firearm detection system including door fixing device
First Claim
1. A firearm detection system for inspecting whether a person passing through a gate positioned near a metal door is carrying a firearm, the system comprising:
- a door fixing device for fixing the door;
a first detection sensor mounted on a doorframe to detect the entrance of a person into the door;
a second detection sensor mounted on an entrance side of the gate to detect the entrance of a person into the gate;
a third detection sensor mounted on an exit side of the gate to detect the departure of a person from the gate; and
a microcomputer for controlling operation of the door fixing device based on the detection results by the first, second, and third detection sensors.

Abstract
A firearm detection system for inspecting whether a person passing through a gate positioned near a metal door is carrying a firearm is disclosed. The system comprises a door fixing device; a first sensor mounted on a doorframe to detect the entrance of a person into the door; a second sensor mounted on an entrance side of the gate to detect the entrance of the person into the gate; a third sensor mounted on an exit side of the gate to detect the exit of the person from the gate; and a microcomputer for controlling the operation of the door fixing device based on the detection results by the three sensors. The efficiency in use is maximized because a door fixing device operates to stop the movement of a door during the inspection procedure so as to prevent the generation of an electromagnetic field by the movement of the door made of similar material to the firearm, thereby preventing a false alarm signal from being generated by the movement of the door when a person carrying no firearm enters the gate.
