Description

Detailed Description of the Invention "Industrial Application Field" This invention is useful for preventing intrusion by suspicious persons when carrying out or carrying in goods by opening and closing doors in computer rooms of banks, telecommunications companies, etc. The present invention relates to a door opening/closing control method that enables prevention.

[Prior Art] Extremely important information is distributed in computer rooms of banks, telecommunications companies, etc. In order to protect this information from the outside, people entering and exiting must be strictly controlled 24 hours a day. For this reason, conventional methods have been used, such as having a security guard stationed at all times, assigning a magnetic card or code number to each person entering the room, and opening and closing the door automatically based on input from a card reader or numeric keypad, or a combination of both. Measures were taken.

[Problems to be solved by the invention] By the way, when goods are brought into or transported into a computer room under the above-mentioned management system,
The following problems arose.

(1) It is not possible to prevent people who do not have a magnetic card (mostly suspicious persons) from entering the room accompanied by a person who has a magnetic card. This means that when you open the door with a magnetic card,
This is because people who do not have cards can also enter the room at the same time.

(2) Even if the security guard determined that the person was suspicious, it was difficult to prevent the person from entering the room if the person was threatened.

This invention has been made in view of the above circumstances, and an object of the present invention is to provide a door opening/closing control method that can prevent suspicious persons from entering or exiting a computer room or the like (separate room) by opening and closing the door. With the goal.

[Means for Solving the Problems] In order to solve the above problems, the door opening/closing control method of the present invention includes a first automatic door that partitions a front room from the outside, a separate room leading to the front room, and a first automatic door that separates the front room from the outside. A door opening/closing control method for controlling opening/closing of a second automatic door that partitions a room, the method comprising: providing a human body sensor in the front room to detect whether the front room is unoccupied;
Each of the external and separate rooms is provided with a card reader for detecting whether or not the card is a legitimate card that is permitted to pass through the first and second automatic doors, and further, the human body sensor, the card reader, and the first A terminal is provided in the front room to which opening/closing switches for the first and second automatic doors are connected to control opening/closing of the first and second doors based on signals from a human body sensor and a card reader. The human body sensor detects that the front room is unoccupied, and detects that the second automatic door is closed by the opening/closing switch of the second automatic door, and the human body sensor provided on the outside detects that the second automatic door is closed. Only when the card reader detects the validity of the card, the terminal sends an opening signal to the opening/closing switch of the first automatic door to permit opening of the first automatic door; A sensor detects that the front room is unoccupied, and an opening/closing switch for the first automatic door detects that the first automatic door is closed, and a card installed in the separate room is provided. The present invention is characterized in that only when the validity of the card is detected by the reader, an opening signal is sent from the terminal to the opening/closing switch of the second automatic door to permit opening of the second automatic door.

[Operation] According to the door opening/closing control method described above, only when the front room is unoccupied, the second automatic door is closed, and the validity of the card is detected by the external card reader, the first automatic door is opened. The automatic door opens to allow entry into the front room from the outside, and items can be brought into the front room from the outside. Note that during this time, the second automatic door remains closed.

On the other hand, only when the front room is unoccupied, the first automatic door is closed, and the card reader in the separate room detects the validity of the card, the second automatic door opens and the door is opened from the separate room to the front room. It becomes possible to enter the room and carry items from the front room to another room. During this time, the first automatic door remains closed.

In this way, a state is created in which only articles exist in the front room, and articles are carried in and out through this state, so that the risk of a suspicious person intruding into another room can be completely eliminated.
