Method for controlling coming and going personnel, and a system thereof
First Claim
1. A method for controlling coming and going personnel at a facility comprising the steps of:
- ionizing air by a discharging device, the air has been contacted with a coming person who entered into a control area provided between outside and inside of the facility;
detecting the ionized air by a mass spectrometer as a molecular weight;
inputting the molecular weight into a control processor;
checking the molecular weight against molecular weights of dangerous substance which have been registered previously into said control processor to detect the molecular weight of dangerous substance in the air;
inputting a signal of the detected dangerous substance into a door driving controller; and
closing a door provided in the control area by operating said door driving controller to prohibit said coming person from entering the facility.

Abstract
A coming and going personnel control system having a high security level by prohibiting a coming person who has dealt with a dangerous substance from entering a facility through a control area is disclosed. Whether a person coming into the control area carries a dangerous substance such as explosive material with him or has dealt with such dangerous substance can be checked by the steps of: ionizing air which has been contacted with the person coming into a control area by a discharging device; the ionized air is detected by a mass spectrometer as a molecular weight; the molecular weight is input into a control processor; and if the detected molecular weight is matched with a molecular weight of dangerous substance which have been registered previously into the control processor, the door in a direction forward to the coming person is closed.
