Next, the operation of the door control device configured as described above will be explained.

First, it is assumed that the door control device is constantly accessed throughout the opening and closing of the bank.

Note that the reason why the store is energized even when the store is closed is because there is a possibility that an intruder may enter the CD corner during the store and be trapped inside due to an earthquake or the like.

This is because the elimination of criminal acts and the danger to the person's body and life are considered to be separate considerations.

So, if an i-quake of 80 gal or more occurs now,
The earthquake sensor (earthquake sensor) senses this and gives an opening command signal to the automatic door (4) via the OR gate α6), and also
S controller Fuchi, S via R game)-, (35)
External shutter (8□) from the controller.

An open command signal is given to (S2). These allow automatic doors (

I) The door opens automatically, allowing those trapped inside the CD corner (2) to escape to the outside, and the external shutter (S) + (s2) is opened, allowing the transparent glass (
7) The situation inside the CD corner (2) can be observed from the outside throughout, and early treatment from the outside can be taken if necessary.

Next, if a fire occurs in or near the CD corner (2), the fire alarm (F), (F2) will detect this, and the same OR gate α6) # m #
(35) and S controller (3), automatic door (4), external shutter (S
□＞r Give an open command signal so that (s2) opens automatically. However, if a fire occurs in combination with an earthquake or on its own, people trapped in the CD corner (2) will be in danger of harming their bodies and lives if they do not escape from there quickly. Since the degree of influence is large, perform the following actions.

That is, the output of the first timer (company) which receives the output from the OR gate □□□ becomes 1H'' after 5 seconds.

At this time, if the automatic door (4) is not opened by more than 50%, that is, the minimum gap necessary for Iruma to pass through, AN
D gate (2)) has a negative input and its output is 1H”
Therefore, the logical product condition of the AND gate (to) is satisfied, and the output of the AND gate (the output of the seagull is the OR game) < 181
guided by. The output of this OR gate 03) gives an electric lock unlocking command signal to the electric lock of the electric lock control door (5), and the person trapped inside the CD corner (2) turns the knob of the electric lock. You can go inside the bank (4),
Escape to the outside is possible through a designated emergency exit.

Furthermore, in the above case, if the electric lock control door (6) does not open, that is, if the electric lock control door (5) does not open even once for two minutes, the entry ND gate The output of the logic gate (0M2) with the output as input becomes H'',
An open command signal is given to the internal shutter (S3) via the AND gate example, the OR gate (7), and the S3 controller example. This makes it possible to escape to the outside through the inside of the bank (4) in the same manner as described above.

As mentioned above, first, the automatic door that has the highest safety and allows quick escape is automatically opened by the external control door opening means, and then, if the automatic door function is inhibited, the next safety As a measure, the electric locking control door is opened by the internal control door first opening means, and if the function of the electric locking control door is disturbed, the internal shutter is opened by the internal control door second opening means as a final safety measure. By automatically opening and taking these triple safety measures, there is no risk that Iruma will remain trapped in the CD corner even in the event of an earthquake, fire, or other disaster, resulting in a higher level of safety. It becomes a door control device.

Note that the above embodiment can also be implemented in the following manner.

(1) In the above embodiment, when a fire occurs, the first internal control door
Although the opening means and the internal control door second opening means are configured to move one time, they may be configured in the same manner as described above even when an earthquake occurs.

(2) In the above embodiment, the electric lock control door and the internal shutter were configured to open in stages, but they may be opened simultaneously.

(Even if a fire occurs outside the 81CD corner, that is, inside the bank, the same structure as in the above embodiment may be used.

(4) An emergency button is installed in the CD corner, and automatic doors, control doors with electric locks, and internal shutters are automatically opened by taking into account the AND condition of the output of this emergency button and the fire or earthquake detection signal. You may also do so.

(6) The automatic door in the above embodiment uses an electric lock.
It may be of any other type, such as a manual group.

(6) Control doors with electric locks may be of any type, such as automatic doors.

(γ) The door that exits to the outside via the inside of the bank may also be controlled in the same way as the electric lock control door and internal shutter.

(3) The state of opening doors and shutters in stages may be displayed or automatically announced.0 [Effects of the Invention] As described above, according to the present invention, the state of opening of doors and shutters in stages may be displayed or automatically announced. In the event of a disaster, we have installed an external control door opening means that automatically opens at least a control door such as an automatic door leading to the outside of the building, so there is no risk of being trapped in a partitioned space such as the CD corner of a bank. This has the advantage that a door control device with high safety can be obtained.
