Description

The present invention relates to a system that manages the opening and closing of a general public during an emergency disaster and the subsequent smooth return to a normal state in an area where entry is prohibited except for related parties.

Conventionally, many entrance / exit management systems have been seen as management systems for areas that are prohibited from entry by persons other than those concerned and areas where only specific persons can enter. Each of them confirms whether or not it has the admission permission qualification and permits the admission. A card and a card radar, an RFIDTAG and a TAG reader are used to check a qualified person. Examples of these can be found in US Pat. Patent Document 3 describes a system that can distinguish entrance / exit using a human body detection sensor and RFIDTAG.
However, there is no similar system for managing access to the general public in the event of an emergency disaster in a specific area and subsequent smooth return to normal conditions. .

Since it is configured as described above, by obtaining emergency disaster information such as earthquakes and tsunamis (broadcast reception), the lockout of the off-limits area is automatically opened, and access to the general public becomes possible. In addition, after a lapse of a predetermined time to be safe (or emergency disaster information cancellation broadcast), it is possible to smoothly lock and return to normal after the general public has moved away.

It is a figure which shows one embodiment of a structure of the emergency evacuation restricted area open / return management system of this invention. It is a figure which shows one embodiment of the operation | movement flow of the emergency evacuation restricted area open / return management system of FIG. It is a figure which shows another embodiment of a structure of the access prohibition area opening / returning management system for emergency evacuation of this invention. FIG. 4 is a diagram showing an embodiment of an operation flow of the emergency evacuation restricted area open / return management system of FIG. 3.

An outline of the function of the emergency evacuation restricted area opening / returning management system according to the present invention is as follows. In general, it is prohibited for anyone other than those involved to enter, and the door is locked so that it cannot be opened. . Many such facilities are public. If there is such a facility nearby at the time of a disaster such as an earthquake or tsunami, it will be temporarily opened as an evacuation site and used until the danger has passed. There is no loss and the utility value of the facility increases. Even if it is a public facility, there is a time when it is necessary to respond to such an emergency. At this time, as in the case of a normal admission management system, the attendees are completely different from those who enter the admission qualified person by confirming with a card or RFIDTAG, and there is no admission qualification. Of course, the card or RFIDTAG A large number of ordinary people who do not have the same must enter. Moreover, there is no manager in charge at the gate. Therefore, it must be changed to a state where communication can be performed from a remote location or automatically at that location. If artificial actions are involved here, if you can not enter due to delay or forget, evacuation will not be in time, and it is important to cover with artificial actions only if it is unlocked automatically and there is a malfunction etc. .
In addition, in the emergency entry and participation of a large number of ordinary people who do not have a card or RFIDTAG, there are the following troublesome problems that must be achieved.
1) The door is automatically unlocked according to the emergency disaster information.
Unlocking is relatively easy.
The main issue that needs to be considered is when the person in charge is not present at the site and must return to normal. In terms of safety, maintenance, maintenance, etc., managerial duties and human burdens tend to be excessive. In such a case,
2) In the case of manual doors and locks, the last evacuees must be securely closed and locked after confirmation.
3) Prior to locking, all evacuees must be confirmed to participate. It is because it will become trouble if it locks in the state where there is a survivor.
In the unlikely event that such a situation occurs, countermeasures are also required.
4) It is necessary to automatically lock and return after a predetermined period of time or by an operation on the management side.
In consideration of such circumstances, an emergency evacuation restricted area open / return management system (hereinafter abbreviated as open / return management system) is configured.
This will be described below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the configuration of an emergency evacuation restricted area open / return management system according to the present invention. In particular, it is an example of using a manual door and bag installed in the past, such as fixing the bag with an electronic lock, opening and closing these doors, and then automatically locking the electronic lock.
FIG. 3 is a diagram showing another embodiment of the configuration of the emergency evacuation restricted area open / return management system of the present invention. In particular, this is an example in which the door is automatically opened and closed, the electronic lock is locked as it is, and no human intervention is involved.
First, the common configuration will be described.
A closing means for making the restricted area a controlled closed space, a gate for entering and exiting the closed area,
Gate opening and closing means for opening and closing the gate and unlocking and locking,
Emergency disaster information acquisition means for receiving emergency disaster information receiving means for receiving information such as emergency disaster broadcasting, or receiving received information from an emergency disaster information receiving means located outside;
Opening time setting means for setting the unlocking time of the gate opening and closing means, and receiving the emergency disaster information, unlocking, timing the opening time, and within the desired time set there An open time counting / time inside / outside judgment means for judging whether the time is over and a control means for controlling the means including these are provided, and when the set time is over, locking or reporting to the manager side. Of course, since it is an electronic device, it is natural to have a power supply.
The closing means and the gate are naturally necessary for the installation environment, and are not necessarily included in the means. Therefore, the following will be described without including them.

These common operations are as follows.
When the emergency disaster information acquisition unit 110 receives the emergency disaster information, it drives the gate opening / closing unit 120 to unlock the electronic lock of the gate door and allow the general public to enter. In the opening time setting means 130, a desired time, for example, 10 hours or the like is set in advance as a time required for evacuation (time until evacuation cancellation). The opening time counting / inside / outside determining means 131 starts counting from the time of emergency disaster information acquisition or unlocking, and determines whether it is within the desired time set by the opening time setting means 130 or the end. When the set time is over, the gate opening / closing means 120 is driven to confirm that the door is closed, and then automatically locks and / or reports to the manager side to return to the normal state.

The above is the main operation, but it would be more convenient to have the following configuration and functions.
The entrance / exit number confirmation means 140 first performs an entrance count for each entrance and obtains the total number M of visitors. Similarly, a participation count is performed for each participation and a total number N of participants is obtained. The number of MN is the number of people who are actually entering. If you count the number of entrances as positive and the number of entries as negative, the number of visitors can be obtained substantially without renewing the subtraction. There are many ways to distinguish between entry and exit. For example, a plurality (two or more) of sensors are arranged in series, and the moving direction can be determined in the sensed order. In addition, entrance and exit gates can be prepared separately. In this case, each may be sensed. As the sensor, a screen switch using light, a foot switch that senses treading, a human sensor, an image sensor, and the like are used. If the number of visitors is substantially 1 in response to the output of the number-of-entry-checking means 140, when a new participation is detected, the participant is determined as the final participant. This is performed by the final contestant judging means 141.

The local manual opening / closing means 121 is manually opened and closed on the spot when an electronic lock is locked due to malfunction or the like even though there are still evacuees, and it is not locked or locked due to other factors of the system. The means 120 is driven, and a switch for driving the gate is provided without going through a normal control route. However, if anyone can operate it from the outside, anyone can enter it at any time. The remote manual opening / closing means 122 is used when an electronic lock is locked due to a malfunction or the like even though there are still evacuees, and is locked or locked due to other factors of the system. When the administrator recognizes that it is necessary, the gate opening / closing means 120 is driven via the communication means 150, and the gate can be driven without going through a normal control route. Incidentally, the local manual opening / closing means 121 and the remote manual opening / closing means 122 are driven by the gate opening / closing means 120 when the emergency side recognizes the necessity when the emergency disaster information cannot be obtained. It can also be opened.

The conversation unit 151 is a unit that can have a conversation with a remote manager on the site via the communication unit 150. In particular, it is possible to enable conversation only in an emergency.
The alarm means 152 sends and receives instructions and warnings to the attendees by voice and display and information related to these to the remote manager side via the communication means 100.
The warning means 153 before the opening time expires is an appropriate time (for example, 10 minutes before) when the desired time set by the opening time setting means 130 is over by the time counting by the opening time counting / time inside / outside judgment means 131. In this case, a time-out warning is issued.
In this regard, the remaining time display means 132 displays the remaining time of the desired time as a result of the time measurement. The emergency use information display means 160 is a means for displaying what should be clearly indicated to general refugees in an emergency such as “disaster evacuation open”.
The control means 101 controls them, and the power source 102 supplies power to them and gives drive power.

The above is a description of the parts common to FIGS. 1 and 3, but the difference between FIGS. 1 and 3 will now be described. In Fig. 1, there are some conventional doors and saddles that must be manually closed, and at least the final contestants have to manually close the doors, and after confirming the closure, lock after waiting for the desired time limit. Is to do. Of course, it is possible to close the contestant each time and unlock it every time the attendee is detected within a desired time.
Therefore, there is a door / claw closing (speech) instruction means 170 for the contestant who instructs the contestant to close the door and bag before locking, and the door state sense for confirming whether the door is closed upon receiving the instruction. There is a means 171 and there is a heel state sensing means 172 for confirming the heel closing. These sensing means may be switches such as electrical contact / non-contact, magnetic coupling, optical circuit conduction / non-conduction in the final state when the door or bag is moved and closed, and image judgment. it can. It is convenient if there is a door state display means 173 and a heel state display means 174 for displaying these sense results.
In Fig. 3, there is no conventional manual door-to-close door or bag, which is an automatic door that closes automatically. The door is locked and unlocked at the same time as the door opens and closes. Is not necessary. There is no door / seal closing (voice) instruction means 170, and there is only a door state sensing means 171 for sensing the open / closed state of the automatic door which is a locking condition. A door state display means 173 is also convenient.

In the above, the configuration of each means has been described with reference to a block diagram. In some cases, the configuration may be configured by hardware such as a switch or an electronic circuit. In this case, the memory is loaded with processing programs for the various means described above, a control program for integrating them, and processing-related data.
The computer and the control program function as control means, and the processing program is executed by the control and functions as each means. As is well known, input devices such as sensors and switches that do not become programs and output devices such as displays, voices, and alarms are used for input / output of processing of processing programs. The configuration and function have been described above.

FIG. 2 is a diagram showing an embodiment of the operation flow of the emergency evacuation restricted area open / return management system of FIG.
FIG. 4 is a diagram showing an embodiment of the operation flow of the emergency evacuation restricted area open / return management system of FIG.
Hereinafter, the operation flow will be described in the order of FIG. 2 and FIG.
In FIG.
(1) Obtain emergency disaster information such as receiving emergency disaster broadcasts. With this as an opportunity,
(2) Start timing of the first opening time. A desired time is set in the memory M1S in advance. The measured time is stored in the memory M1 as needed.
(3) The electronic lock is unlocked. Note that the order of (2) and (3) is arbitrary, and may be reversed or simultaneous.
(4) It is determined whether the current time is within the first opening time. If the desired time has passed, the lock of (23) is obtained. If it's in time,
(5) Perform admission monitoring (number of people detection). The number of visitors is accumulated in M2.
(6) Perform participation monitoring (number detection). The number of participants will be accumulated in M3.
(7) It is detected whether it is the final contestant. When a participant is viewed before counting, M2 data-M3 data is 1 and when viewed after counting, M2 data-M3 data is 0. Other than that, it is not the final contestant.
If you are not the final contestant,
(8) It is determined whether the current time is within the first opening time. Within the time, repeat from (5) admission monitoring. If it ’s overtime, there ’s a remnant when the desired time is over,
(9) The event will be broadcasted. To set an extended time only for the first participation reminder broadcast,
(10) See if it is the first time. The number of times is stored in the memory M5.
(11) Set the extension time. The memory M6S is entered.
(12) Check if it is within the extended time. If it is within the extension time, repeat from (5) admission monitoring.
Naturally, the participation reminder broadcast is repeated until the extended time expires.
Alternatively, an upper limit of the number of broadcasts may be determined instead of the extension time, and it may be determined whether or not it is within this.
When the extension time expires,
(13) Notify the remote management and repeat from (5) admission monitoring.

If you become a final contestant in (7),
(14) Instruct the contestant to close the door.
(15) Check if the door is closed. The maximum number of times (time) of the confirmation operation is predetermined as M7.
If the door is still not confirmed,
(16) Is the number of times or time within the range? The cumulative number or time enters M8.
If it is within the range, return to (14) and repeat.
If out of range,
Make a report at (17) and return to (14) to repeat.

If it is confirmed that the door is closed,
(18) The closing instruction is given to the contestants.
(19) Check if the claw is closed. The maximum number of times (time) of the confirmation operation is previously determined as M9.
If clogging is not yet confirmed,
(20) Is the number of times or time within the range? The cumulative number or time enters M10.
If it is within the range, return to (18) and repeat.
If out of range,
Make a report at (21) and return to (18) to repeat.
(Of course, when there is no wrinkle and it closes only with a door, (18) to (21) is unnecessary.
If the closure is confirmed,
(22) It is determined whether the current time is within the first opening time.
If it is within the time, return to (5) and repeat.
If it ’s overtime,
(23) Lock.
(24) The memory data is initialized.
(25) It is checked whether the local manual open / close button has been pressed.
(26) If it is pressed, the second opening time measurement is started. The desired time is set to M11S.
(27) Unlock. The order of (26) and (27) may be reversed or simultaneous.
(28) See if it is within the second opening time.
If it is out of time (elapsed), the locking of (23) is performed.

The above is the operation flow for the example of FIG.
This flow can take various forms. For example, in the case of (7) confirming the final contestant and instructing the door to be closed, etc., but instructing each contestant to lock at the end of the first opening time. In this case as well, the final contestant may or may not be locked. If the conditions are not locked, visitors may remain at the time of locking. This is dealt with by the local manual opening / closing of (25). In such a case, it is not necessary to know the remaining number in the area, so that entrance monitoring can be omitted. In addition, participation monitoring without detecting the number of people is also acceptable. In this way, various changes can be made in other parts.

Next, in FIG. 4, the automatic door itself has a lock function.
The difference from FIG. 2 is that there is no processing from (14) to (21), and the other processing is the same.
The desired time can be set as a margin time after the final contestant appears after unlocking.
In this case, it is natural that the flow is different.

In addition, since an event such as an earthquake that gives emergency disaster information occurs rarely, such a system must ensure that there is no malfunction in preparation for the occurrence of the event. Therefore, temporary emergency disaster information is generated, and unlocking / locking simulation operation is performed at an appropriate time interval set in advance or by activation of an administrator at any time to ensure the completeness of the operation, etc. It is convenient to have the function of a self-diagnosis program.

As described above, in the emergency evacuation restricted area open / return management system according to the present invention, if emergency disaster information is acquired, the locked area of the restricted area is usually released and used for evacuation of the general public. After a period of time, it can be automatically and reliably locked and returned to the normal off-limits area, which is extremely convenient for industrial use.
