DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for automatically opening and closing a building shutter suitable for an entrance of a banking dispenser or the like of a bank.

[0002]

2. Description of the Related Art In general,
The opening and closing control of the shutter curtain of the architectural shutter built at the seed entrance is, for example, unattended based on a command from the central control room at the time of opening and closing. In this case, if the shutter curtain is closed unconditionally based on the arrival of time, there is a risk that a person may be left behind in the room.

[0003] Conventionally, as shown in Japanese Patent Publication No. 1-56236, a search is made as to whether or not a person is left in the room. If a person is found, the shutter curtain is restricted from being closed. In some cases, a leftover person is urged to go out of the room, and if a person is searched for even after a lapse of a predetermined time, the person is notified to a management room.

However, in this apparatus, when a person is searched during the closing of the shutter curtain, the shutter curtain is stopped and closed if necessary, and the shutter curtain is opened if necessary. The curtain itself may be in a half-open state or a fully-open state, and there is a problem that a third party outside the room who sees the curtain may enter the room judging arbitrarily if it is still in time.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made in order to provide an automatic system for opening and closing a building shutter capable of eliminating these disadvantages. A shutter curtain that opens and closes the entrances inside and outside the room, opening and closing drive means for opening and closing the shutter curtain, and opening and closing control means for outputting an opening and closing control command to the opening and closing drive means In the automatic opening / closing system for architectural shutters, the opening / closing control means includes a first search means for searching for the presence of a person remaining in the room and outputting a first search signal, and a person being in the vicinity of the indoor side entrance. At least a second search means for searching for the result and outputting a second search signal and a notification means for notifying a person in the room are connected, and the opening / closing control means further includes An opening / closing control command output unit for outputting an opening / closing control command to the opening / closing drive means at the arrival of the set opening / closing time; and, after the arrival of the closing set time, the first search signal of the temporary opening allowable time set in advance. A notification command output unit that outputs a notification command for guiding a person who remains in the room to the entrance to the notification means when an input is received; and a second search signal during the temporary opening allowable time. A temporary opening command output unit for outputting a temporary opening control command to the opening / closing drive means so as to be in a preset opening state through which a person can pass when an input is provided; Things.

According to the present invention, by this configuration, it is possible to effectively prevent a general third party outside from entering the room.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a shutter curtain of an architectural shutter. The shutter curtain 1 is installed at an entrance (opening) of a room R where a banking dispenser of a bank is installed. The shutter curtain 1 is spirally wound around a take-up drum 2 accommodated in the ceiling of the entrance and exit, and the take-up drum 2 rotates forward and reverse based on the driving of the opening / closing drive means 3 so as to open and close the entrance / exit. Opening and closing are the same as before.

Reference numeral 4 denotes opening / closing control means for implementing the present invention, which is disposed in a centralized control room or the like.
The opening / closing control means 4 includes the opening / closing drive means 3, a first search means 5 for searching for a person remaining in the room R, and an indoor entrance / exit. Second search means 6 for searching that there is a person nearby, room R
First notifying means 7 for notifying a person remaining inside, second notifying means 8 for notifying a person near the outside of the room at the entrance,
Obstacle detection switch ISW, full-open detection switch (upper limit switch) LSU, full-close detection switch (lower limit switch) LSD, stop switch SSW, open switch O provided at the lowermost end of the shutter curtain 1
SW, closing switch DSW, automatic control switching switch A
It is connected to various means such as a switch, an alarm means 12, and switches. Here, the first and second search means 5 and 6 may employ various types of search systems which are generally known for searching for a dynamic object by using, for example, far infrared rays, and may be used as an obstacle detection switch ISW. The tape switch is generally used, but the present invention is not limited to this, and may be a tape switch using an air transmission medium such as far infrared rays. Any means can be used as long as it detects the presence of a person or an object in the trajectory. In the embodiment, the stop switch SSW, the open switch OSW, and the close switch DSW are assumed to be separately provided at the entrance and exit, and are not assumed to be separately provided in the control room. Needless to say, it may be further provided. And these switches SSW, OSW, DS in the embodiment
Of the switches W, the stop switch SSW is exposed to a switch box with a lock (not shown) so that the switch can be arbitrarily operated. In this case, the stop switch SSW is covered with a resin cover to handle it as an emergency stop switch, and a precautionary note such as "Press in case of emergency." If it is attached, careless switch operation will be avoided, and this is preferable from the viewpoint of safety, crime prevention, etc., but is not limited thereto. These switches are not always necessary for implementing the above.

Now, the opening / closing control means 4 is constituted by using a central control unit (CPU) 10 composed of a micro computer. And a signal from various necessary means such as opening / closing time setting means (preferably, the opening / closing time can be changed and stopped according to the date) is input. And perform necessary signal processing based on these input signals,
Then, various control commands are sent to the first and second notification means 7, 8,
It outputs to the opening / closing drive means 3.

Next, the procedure of the control system of the opening / closing control means 4 will be described with reference to flowcharts shown in FIGS. First, the main switch is turned on, the power is supplied, and the system is started.
In this initially set state, the open / close control means 4 determines whether or not the automatic control state is in effect, that is, the automatic control switching switch ASW
Is determined to be in a state of being operated, and when it is determined that the state is an automatic control state, the time command from the clock unit CL connected to the opening / closing control means 4 determines whether the time is in the closing time range or in the opening time range. It is determined whether the time is in the time domain, and when it is determined that the time is in the closed time area, the automatic closing control system is systemized as a subroutine when it is determined that the time is in the open time area. Similarly, when it is determined that the state is the manual control state, the manual control system is systemized as a subroutine.

First, a manual control system will be described. In this system, in order to avoid forgetting to switch to automatic control, an alarm command is issued to the alarm means 12 when a manual control system is provided. In order to notify the administrator that the control has been switched to the manual control.
In this case, it is determined whether the shutter curtain 1 is in the fully opened state or the fully closed state.
When it is determined that the switch is in the fully open state or the half open state, the operation is in a state of waiting for the operation of the closing switch DSW. Is output. When the fully closed detection switch LSD detects that the shutter curtain 1 is in the fully closed state, the closing drive is stopped. However, during the closing operation, the stop switch is stopped. When a human operation signal of the SSW or an obstacle detection signal of the obstacle detection switch ISW is input, the closing drive is stopped. On the other hand, if it is determined that the vehicle is in the fully closed state or the half open state,
Although the opening switch OSW is waiting for operation,
In this case, the control system is the same as the closing operation except that there is no emergency stop by the obstacle detection switch ISW.

Next, an automatic opening control system will be described.
The open / close control means 4 sets a timer to start a timer count, and opens the open / close drive means 3 when it is determined whether or not is open. A drive command is output, and based on this, the opening / closing drive means 3 drives the opening of the shutter curtain 1. By inputting a full open signal from the full open detection switch LSU which detects that the shutter curtain 1 has reached the full open state, the output of the open drive command is stopped and the timer is reset. During the open drive, it is determined whether or not a stop command from the stop switch SSW has been issued. When it is determined that the stop switch SSW has been output, the output of the open drive command is stopped and the timer is reset. An alarm issuing signal is set to be output until the operation signal of the opening switch OSW is input to the alarm means 12 provided in the control room. Then, when an operation signal of the opening switch OSW is input, the automatic opening drive control is restarted again. Here, the opening switch O
As the operation signal of the SW, it is possible to automatically generate a signal as the predetermined time elapses. However, it is necessary to improve the safety by limiting the signal to a manual operation of the opening switch OSW. It is preferred that Further, when there is no stop command from the stop switch SSW, the timer time (the time during which the shutter curtain 1 normally opens and closes has passed, and if the time exceeds this, some abnormality is expected in the opening / closing drive means 3. If it is determined that the predetermined time has elapsed, the opening drive is stopped, the timer is reset, and the administrator is notified by outputting an alarm signal, and the first and second times are notified. Notification means 7, 8
At the same time, a voice notification such as "Please do not approach the entrance" is given to the people inside and outside the room R to notify the person not to approach the closing locus of the shutter curtain 1,
The control system is set to switch from the automatic control system to the manual control system.

Finally, a closed automatic control system in which the present invention is implemented is systematized as follows. That is, in this subroutine, when the subroutine of the automatic closing control system is started, first, it is determined whether or not the shutter curtain 1 is in the fully closed state based on a detection signal from the fully closed detection switch LSD. When it is determined that the vehicle is in the fully closed state, the closing time (for example, 7:00 pm)
Minutes) to a preset temporary opening allowable time (for example, 10 minutes).
) Is determined (time 7:10 pm). If it is determined that the temporary opening allowable time has elapsed, it is determined that the time has expired, and the opening of the shutter curtain 1 is controlled based on a search for the presence of a person in the room, as described later. And when the search signal of a person is input from at least one of the first and second search means 5 and 6, an alarm issuance signal is output to the alarm means 12. It is set to notify the administrator.

If it is determined that the shutter curtain is not in the fully closed state, a timer is set and a closing drive command is output to the opening / closing drive means 3 so that the closing operation of the shutter curtain 1 is performed. Then, at the stage of the closing drive, it is further determined whether or not the vehicle is in the fully closed state in the same manner as described above. If it is determined that the vehicle is in the fully closed state, the output of the closing drive command is stopped and the timer is reset. On the other hand, if it is determined that the switch is not in the fully closed state, it is determined whether an operation signal of the stop switch SSW has been input, whether an obstacle detection signal has been input from the obstacle detection switch ISW, and whether a timer time has elapsed. A determination is made as to whether or not. When an operation signal is input from the stop switch SSW, and when it is determined that the timer time has elapsed, the same control as in the automatic opening control system is performed, but the obstacle detection is performed. When the signal is input, in addition to the control when it is determined that the timer time has elapsed, the control unit 3 outputs a control command to the opening / closing drive unit 3 to perform the obstacle avoidance drive. This control is performed in order to prevent the obstacle from being caught by the shutter curtain and unable to escape. For example, the shutter curtain 1 is raised to the fully open position, or a predetermined height (from the obstacle detection position). For example, it is set so as to perform control such as raising by 20 cm) and stopping.

Further, when it is determined that the vehicle is not in the fully closed state, it is determined whether or not the temporary opening allowable time has elapsed. If it is determined that the elapsed time has elapsed, a control command is output to the opening / closing drive means 3 so that the shutter curtain 1 is fully closed, so that the shutter curtain 1 described later cannot be temporarily opened. Is controlled.
On the other hand, when it is determined that the temporary release allowable time has not elapsed, it is further determined whether or not a search signal of a person has been input from the first and second search means 5 and 6. Here, when a search signal for a person is input from the second search means 6, it is determined whether or not a person has been searched in the previous search. If it is determined that there is no person search in the previous time and this is the first time, the output of the closing drive signal is stopped, the timer is reset, and the shutter is moved to the opening / closing drive means 3 to such an extent that a person can go in and out. A temporary opening control command to open the tar curtain 1 is output, and the shutter curtain 1 is temporarily opened by a preset required height (either fully open or half open). In addition, when it is determined that the person search has been completed in both the previous time and the current time, an alarm issuance is issued from the alarm unit 12 and
During the temporary open permission time, the temporary open state is controlled to be maintained. At this time, from the first notification means 7,
For example, an audio signal such as "Please exit the room immediately when the shutter opens" is issued to guide the user to leave the room. On the other hand, for the second notification means 8, for example, "Do not enter the room" Please do so. "Is controlled so as to check that a person who is outdoors enters the inside by issuing an audio signal such as Further, when it is determined that the input of the human detection signal was previously performed but the input of the human detection signal was not performed this time, this indicates that the person has left the room or moved to a part of the room that is not searched by the second search means 6. In this case, the shutter curtain 1 described above is again used.
It is set so that the closing control is performed.

On the other hand, if there is no input of the person search signal from the second search means 6 but a signal input of the person search is input in the first search means 5, an alarm command is output to the alarm means 12. At the same time, the first notification means 7 is notified by voice such as "Go to the entrance and exit immediately from the room when the shutter is opened." To guide the person remaining in the room to the entrance. It is set as follows.

In the embodiment of the present invention constructed as described above, in the automatic control state in which the automatic control switching switch ASW is operated, the automatic closing control system is started when the set closing time comes. In case,
If the first search means 5 finds that a person still remains in the room R within the predetermined temporary opening allowable time, the first notification means 7 searches for a person. You will be guided near the doorway. When the person guided in this way comes to the vicinity of the doorway, or when a person is near the doorway from the beginning and searched by the second search means, the shutter curtain 1 passes through the person. In addition to the temporary opening by the required height, the first notification means 7 guides the person to leave the room, and in this case, the second notification means 8 allows an outdoor person to escape. You will be checking into the room. As a result, when a person remains in the room R even after the set time for closing, if the person is temporarily opened and the person can leave the room within the temporary opening allowable time, the first search is performed. In the search of the means 5, the shutter curtain 1 is temporarily opened as the remaining person comes near the doorway and is searched by the second search means 6 without being temporarily opened. In addition, the temporary opening time can be shortened as much as possible, and it is possible to effectively avoid the unintentional entry of a third party outside the room. In addition, the temporary opening of the shutter curtain is performed only within a predetermined temporary opening allowable time, and thereafter, the shutter curtain is not opened any more.
It will be more excellent in security.

Furthermore, in this case, since the search by the second search means 6 has priority over the search by the first search means 5, for example, when a plurality of people remain in the room, if only one person approaches the entrance, In response to this, shutter curtain 1
Is temporarily opened, and as in the case where the first search means 5 is prioritized, the shutter curtain 1 cannot be temporarily opened unless the first search means 5 does not search for a person. It is suitable without any. Of course, any control may be used as long as the subsequent control based on the search control by the first and second search means 5 and 6 is performed independently.

It should be noted that the present invention is not limited to the above-described embodiment, but a notifying means for guiding a remaining person to the entrance / exit side (first notifying means of the above-described embodiment).
As the notification is not limited to the sound signal, it may be something like a guidance indicator light, and, as the notification means, the guidance may be provided by the search of the first search means,
In the search by the second search means, notification may not be performed, and further separate notification means may be provided. Such a method is effective when the room is large.

[0020]

In summary, since the present invention is configured as described above, the shutter curtain is automatically closed when the closing time comes,
In this case, if the first search means finds that a person still remains in the room within the predetermined temporary opening allowable time, the first notification means makes the person notified by the first notification means. To the doorway. When the person guided in this way comes to the vicinity of the doorway, or when a person is near the doorway from the beginning and searched by the second search means, a temporary opening command is output and the shutter is opened. The tar curtain will be opened temporarily. As a result, if a person remains in the room even after the closing time, the first search means can be temporarily opened and the person can leave the room within the temporary opening allowable time. In this search, the temporary opening of the shutter curtain is performed only when the remaining person comes near the doorway and is searched by the second search means without temporary opening. The opening time can be shortened as much as possible, and it is possible to effectively avoid the careless entry of a general third party who is outside the room. In addition, the temporary opening of the shutter curtain is performed only within a preset temporary opening allowable time, and the shutter curtain is not opened any more thereafter, so that the security is further improved.
