ABSTRACT:
A pistol detection system including a main control unit for controlling all constituting units of the system, a magnetic force generating unit for generating a control signal for a generation of magnetic fluxes, a gate for generating magnetic fluxes of a desired intensity while receiving the generated magnetic fluxes, thereby generating an induced voltage, a magnetic force receiving unit for detecting the induced voltage, thereby determining whether or not a person who passes through the gate carries a pistol, a camera for picking up an image of the person who passes through the gate while carrying a pistol, a time generating unit for outputting time information, an image signal processing unit for composing an image signal generated from the camera with the time information generated from the time generating unit, storing the resultant signal, an automatic dialing unit for automatically dialing a previously set telephone number, and interior and exterior alarm lamps respectively for generating an alarm and emitting light in the interior and exterior of a place where the system is installed, when a pistol is detected. Thus, the pistol detection system of the present invention provides an effect of providing an effective preventative measure against the occurrence of crimes using pistols.
