Description

  The present invention relates to a door opening / closing control system, a door opening / closing control device, and a door opening / closing control program for controlling opening / closing of a door when a disaster occurs.

  When an earthquake occurs, due to the building distortion caused by the earthquake, the door cannot be opened even though the lock is unlocked. In such a case, a person existing in the building loses the evacuation route and becomes trapped in the building. Therefore, there is a technique for opening the door when the control device detects the occurrence of an earthquake. There exists patent document 1 regarding the technique of opening a door.

  Patent Document 1 discloses a technique in which when a seismic sensor included in a control device senses the occurrence of an earthquake, the control device unlocks the locking device and the opening device opens the door.

  On the other hand, a fire may occur due to an earthquake. Therefore, measures are taken to prevent the spread of the fire by closing the fire door to reduce the flow of air in the building. Therefore, there is a technique for closing a door when a person passes without leaving the door open. There exists patent document 2 regarding the technique which controls opening and closing of a door.

  In Patent Document 2, when an earthquake or fire occurs, the evacuation guidance system detects the position of the evacuation guidance target person from the biometric sensor possessed by the evacuation guidance target person, opens a nearby gate or entrance, and after passing A technique is disclosed in which the process of closing the gate or the like is repeated to guide the evacuation target person to the exit.

  Since patent document 2 opens and closes a door at any time after the occurrence of an earthquake, it cannot be applied when the door cannot be opened due to the distortion of the building due to the earthquake. Furthermore, in order for a person to grasp a door in the vicinity, the evacuation target person must hold a biometric sensor. On the other hand, since Patent Document 1 is a technique that opens without specifying a door, there is a possibility of promoting the expansion of a fire when a fire due to an earthquake occurs.

  Therefore, there is a need for a technique that secures an evacuation route for a door in the vicinity of a person from the detection of the initial tremor of the earthquake to the arrival of the main movement so that the door does not close.

  It is an object of the present invention to provide a door opening / closing control system, a door opening / closing control device, and a door opening / closing control program that prevent a person from closing a door that exists in the vicinity before the main motion of an earthquake arrives.

  In order to solve the above problems, a door opening / closing control device disclosed in the present invention fulfills a locking function when a communication unit that receives disaster occurrence information from an information providing device and the communication unit receives the disaster occurrence information. It has a control part which inspects whether the door provided with a metal fitting is an open state, and projects the metal fitting with which the door is equipped if it is an open state.

  According to the present invention, it is possible to identify a door that is likely to have a person in the vicinity based on the open state of the door. Further, by controlling the specified door not to be completely closed, it is possible to prevent the door from being opened due to the distortion of the building due to the earthquake. When a person passes, the door is opened by human power to allow the person to pass. On the other hand, when the person is not passing, the opening of the door is kept to a minimum to reduce the air flow. In addition, it is possible to prevent the fire from spreading when a fire occurs.

  Detailed examples of the present invention will be described below.

  FIG. 1 is a functional diagram of a door opening / closing control system according to an embodiment of the present invention. The present embodiment is a door opening / closing control system that controls the opening and closing of a plurality of doors in a building having a plurality of doors such as a large-scale facility. On the other hand, when controlling the opening / closing of one door, the door opening / closing control can be performed in the lock device 21 as described later.

  The door opening / closing control system includes a door opening / closing control device 1 and a plurality of lock devices (lock device 21, lock device 22 ...). Hereinafter, the lock device 21 will be described as a representative of the lock device. The door opening / closing control device 1 and the key device 21 are connected via a communication line 4, and the information providing device 3 is further connected to the communication line 4 via a public line network 5.

  When the occurrence of an earthquake is detected, the door opening / closing control device 1 instructs the key device 21 so that the key device 21 does not close the door.

  Here, the door 1001 will be described with reference to FIG. The door 1001 is a hinged door, and opens and closes by drawing an arc around a portion stopped by a hinge 1002. That is, the state in which the door 1001 is housed in the outer frame 1003 is a state in which the door 1001 is closed. From the closed state, the door 1001 is drawn in an arc around the axis, that is, the door 1001 is detached from the outer frame 1003. The state is a state where the door 1001 is open.

  Further, the door 1001 is always directed in a direction in which the door 1001 is to be accommodated in the outer frame 1003 when no force is applied from the outside. That is, the door 1003 released by the person is closed even if it is not closed by the person.

  The lock device 21 is a computer having a communication function. For example, the lock device 21 is an electronic lock or a card lock. Then, the lock device 21 controls a lock tightening mechanism provided in the door 1001. The lock is a metal fitting that performs a lock function, and has a dead bolt 1004 and a latch bolt 1005 as a tightening mechanism. That is, the lock function is performed by the dead bolt 1004 and the latch bolt 1005. An enlarged view of a portion surrounded by 1008 is shown in 1009.

  The deadbolt 1004 is also called a saddle and is a mechanism for full-scale locking by being stored in a receiving seat 1006 provided on the outer frame 1003 side, and is operated by a key, thumb turn, or electrical signal. It is a bolt. The latch bolt 1005 is a mechanism that temporarily locks the door against wind and the like by being housed in a receiving seat 1006 provided on the outer frame 1003 side. The bolt is operated by a knob or an electrical signal. It is.

  That is, when the door is open, the dead bolt 1004 is stored on the door 1001 side, and the latch bolt 1005 protrudes. When the door 1001 closes, the dead bolt 1004 is stored on the door 1001 side, and when the outer frame is touched, the latch bolt 1005 is stored on the door 1001 side, and the arc angle drawn by the door around the hinge 1002 disappears. At this point, the latch bolt 1005 protrudes and is stored in the seat 1006. When locked, the dead bolt 1004 protrudes and is stored in the seat 1006.

  On the other hand, the outer frame 1003 may be deformed when the building is distorted by an earthquake or the like. If the outer frame 1003 is distorted while the door 1001 is in the outer frame 1003, the door 1001 is removed from the outer frame 1003 regardless of the protruding state of the latch bolt 1005 or the dead bolt 1004 even if a person tries to open the door 1001. Instead, the door 1001 cannot be opened. Therefore, if the door 1001 is detached from the outer frame 1003 at the time when the main movement of the earthquake arrives, the door 1001 can be opened even if the outer frame 1003 is distorted.

  Returning to FIG. 1, the information providing device 3 is a device that detects the occurrence of an earthquake and provides disaster occurrence information related to the earthquake, such as a computer that provides a disaster information providing service used by the Japan Meteorological Agency or private companies. is there. Disaster occurrence information is information that includes predicted values such as disaster scale for each region and the arrival time of major motions of earthquakes that occurred.For example, initial tremors of earthquakes can be detected and detected as major earthquake early warnings provided by the Japan Meteorological Agency. This information alerts the arrival of motion.

  The functional part of the door opening / closing control device 1 will be described. The door opening / closing control device 1 includes a communication unit 10, a door opening / closing control unit 13, a disaster information database (hereinafter referred to as DB) 14, and a lock information DB 15.

  The communication unit 10 is connected to the communication line 4 and has functional units including a reception unit 11 and a transmission unit 12. In the following description, it is assumed that the process of receiving data is performed by the receiving unit 11 of the communication unit 10 and the process of transmitting data is performed by the transmitting unit 12 of the communication unit 10.

  The receiving unit 11 is a processing unit that performs processing to receive data from another computer connected via the communication line 4. For example, the receiving unit 11 receives from the key device 21 information regarding whether or not the door controlled by the key device 21 is open, or receives disaster occurrence information from the information providing device 3.

  The transmission unit 12 is a processing unit that performs processing for transmitting data to another computer connected via the communication line 4 and transmits, for example, a command that causes the lock device 21 not to close the door.

  A state where the door is not closed will be described with reference to FIG. The dead bolt 1004 or the latch bolt 1005 is protruded in a state where the door 1001 is open, and is fixed in the protruding state. Accordingly, the dead bolt 1004 or the latch bolt 1005 is held by the outer frame 1003, and the door 1001 is not completely closed. For example, if the lock is locked, the dead bolt 1004 protrudes and is fixed in that state. Therefore, when the door 1001 is locked in an open state, the dead bolt 1004 is held by the door 1001 and the door 1001 is attached to the outer frame 1003. Do not fit.

  That is, the door 1001 can be prevented from closing. That is, the lock device 21 controlling the opening and closing of the door is to control the protruding state of the locking mechanism (dead bolt 1004 and latch bolt 1005) provided on the door.

  Returning to FIG. 1, the door opening / closing control unit 13 is a processing unit that identifies the locking device 21 and prevents the door controlled by the locking device 21 from being closed. For example, the door opening / closing control unit 13 refers to the lock information DB 15 to identify the key device 21 that controls the door in the open state, and causes the lock device 21 to control the lock of the door.

  The disaster information DB 14 is a storage unit that stores conditions for starting the door opening / closing control process. Details will be described later. The disaster information DB 14 may not be included in the door opening / closing control device, and may be included in, for example, a central management computer (not shown) connected to the information providing device 3. In this case, the central management computer that manages a plurality of buildings receives disaster occurrence information from the information providing device 3, and sends a door opening / closing control start command to the door opening / closing control device 1 of the building where the door opening / closing control should be started. What should I do? That is, the receiving unit 11 of the door opening / closing control device 1 is connected to the central management computer via the communication line 4.

  The lock information DB 15 is a storage unit that stores information regarding each key device 21. Details will be described later.

  Then, the function part of the locking device 21 is demonstrated. The lock device 21 includes a communication unit 210, a control unit 213, and a door monitoring unit 214. As will be described later, the door monitoring unit 214 may not be included in the lock device 21.

  The communication unit 210 is connected to the communication line 4, and has functional units such as a reception unit 211 and a transmission unit 212. In the following description, it is assumed that data reception processing is performed by the reception unit 211 of the communication unit 210, and data transmission processing is performed by the transmission unit 212 of the communication unit 210.

  The receiving unit 211 is a processing unit that performs processing for receiving data from another computer connected via the communication line 4, and receives, for example, a command for preventing the door from closing from the door opening / closing control device 1.

  The transmission unit 212 is a processing unit that performs a process of transmitting data to another computer connected via the communication line 4. For example, is the door provided to the door opening / closing control device 1 opened? Notify information about whether or not.

  The control unit 213 is a processing unit that gives an instruction to prevent the door provided with the own device 21 from closing when receiving a command from the door opening / closing control device 1 to prevent the door from closing. For example, the locking instruction is given with the door open, and the dead bolt is projected.

  The door monitoring unit 214 is a processing unit that monitors the open state of whether or not the door controlled by the device 21 is open, and notifies the control unit 213 of the monitored open state.

  The monitoring of the door open state will be described with reference to FIG. For example, the door monitoring unit 214 detects the opening of the door when the door 1001 draws an arc having a center angle greater than or equal to a certain axis around the axis of the hinge 1002, and when the center angle of the arc becomes less than or equal to a certain angle. It is a sensor that detects that the door is closed. That is, it is provided on the hinge 1002, and when the opening of the door 1001 is detected, it is transmitted to the control unit 213 of the lock device 21. Then, the control unit 213 notifies the transmission unit 212.

  As described above, the door being open is a state in which the door draws an arc around the axis from the closed state. However, in this embodiment, it is necessary to operate the lock so that the door does not close in a predetermined case. Therefore, the constant central angle should be larger than the moment when the door is opened (for example, the central angle is infinitely close to 0 degrees) so that the door does not fit in the outer frame while controlling the lock. Better.

  The door monitoring unit 214 is provided as a magnet sensor 1007 on the door 1001 and the outer frame 1003, and detects the opening of the door when the magnets of the magnet sensors 1007 provided on the door 1001 and the outer frame 1003 are separated. It may be detected that the door is closed by the contact of two magnets. In this case, for example, as shown in FIG. 8, a magnet sensor 1007 is provided, and the detected opened state is transmitted to the control unit 213 of the lock device 21. Then, the control unit 213 notifies the transmission unit 212.

  An example of a data table stored in the disaster information DB 14 is shown in FIG. The building manager or the like stores the conditions for starting the door opening / closing control process in the disaster information DB 14 in advance. A data table example related to the first embodiment to be described later is shown in (A), and a data table example related to the second embodiment is shown in (B). The disaster information DB 14 may include some of these items, and may further include the items of one embodiment in the data table of the other embodiment.

  In the first embodiment shown in FIG. 2A, the disaster information DB 14 stores the item “disaster scale threshold” 141. In the second embodiment shown in FIG. 2B, the disaster information DB 14 includes an item “disaster scale threshold” 141, an item “disaster occurrence time” 142, and an “opening time threshold” 143 for each building to be controlled. Are stored in association with each other.

  The item “disaster scale threshold” 141 of the disaster information DB 14 is a data area for storing the scale of an earthquake for starting the door opening / closing control process. For example, “Seismic intensity 6” is stored. If the disaster scale included in the received disaster occurrence information is seismic intensity 6 or more, the door opening / closing control apparatus 1 starts the door opening / closing control process.

  As described above, when the central management computer manages a plurality of door opening / closing control devices 1, the disaster information DB 14 included in the central management computer further includes the items “building ID”, item “region”, and item “door opening / closing”. The control device address ”may be provided in association with the“ building ID ”(not shown).

  The item “building ID” is a data area for storing information for identifying a building. For example, a building name such as “ABC building” or a symbol uniquely assigned to the building is stored. The item “region” is a data region for storing information for identifying a region where a building exists. For example, a place name such as “Nakahara-ku, Kawasaki City” or a symbol uniquely assigned to the area is stored. The item “door opening / closing control device address” is a data area for storing the address of the door opening / closing control device 1 that manages the building. For example, an address such as “11.11.11.11” is stored.

  Thus, based on the disaster occurrence information received by the central management computer, when the disaster scale in the “region” corresponding to the building ID is larger than the disaster occurrence threshold corresponding to the building ID, the door of the building ID The opening / closing control device address can be read, and a door opening / closing control processing start command can be transmitted to the transmission unit 11 of the door opening / closing control device.

  The item “disaster occurrence time zone” 142 of the disaster information DB 14 is a data area for storing information related to the time zone when the earthquake occurred. For example, “0:00 to 6:00” is stored. When the time when the door opening / closing control device 1 receives the disaster occurrence information is included in “0:00 to 6:00”, the disaster scale threshold 141 is “seismic intensity 5”.

  The item “opening time threshold” 143 of the disaster information DB 14 is a data area for storing information relating to a certain time. For example, “60 seconds” is stored. Door opening / closing control when the latest date and time when the door controlled by the lock device 21 stored in the lock information DB 15 described later is opened is later than the time when the opening time threshold is subtracted from the reception of disaster occurrence information. The unit 13 specifies the lock device 2 as a control target. That is, when the latest date and time is closer to the current time than the past time when the opening time threshold is traced from the reception of the disaster occurrence information, the door opening / closing control unit 13 specifies the lock device 21 as a control target.

  An example of a data table stored in the lock information DB 15 is shown in FIG. The lock information DB 15 stores “lock ID” 151, “lock address” 152, “release information flag” 153, and “last release date” 154 in association with each other. The lock information DB 15 may include some of these items, and necessary items may be appropriately installed in the embodiment.

  The item “lock ID” 151 of the lock information DB 15 is a data area for storing information for uniquely identifying the lock device 21. For example, “A” is stored. The item “lock address” 152 of the lock information DB 15 is a data area for storing address information of communication means included in the lock device 21. For example, the address “12.34.56.78” of the communication means of the lock device “A” is stored in association with the lock device A.

  The item “open state flag” 153 of the lock information DB 15 is a data area for storing information indicating whether or not the door controlled by the lock device 21 is open. The actual processing will be described later. For example, if the door controlled by the locking device “A” is in the open state, “1” is stored, and if the door controlled by the locking device “B” is in the non-open state (the door is closed). “0” is stored.

  The item “last opened date” 154 of the lock information DB 15 is a data area for storing the date and time when the door controlled by the lock device 21 was last opened. For example, the date and time “2009.3.10 12:00:00” when the door controlled by the lock device “A” was last opened (currently opened in FIG. 3) is stored, and “March 2009” is stored. It shows that the door controlled by the locking device “A” was opened at “10: 12: 00: 00”. Specifically, the date and time when the door opening / closing control unit 13 stores “1” in the “open state flag” 153 is stored in the “last open date and time” 154, and “1” is stored in the “open state flag” 153. Each time the “last open date” 154 is updated.

  First, the movement related to each processing unit shown in FIG. 1 before the reception unit 11 of the door opening / closing control device 1 receives disaster occurrence information from the information providing device 3 will be described with reference to FIG. FIG. 4 is a processing flow for updating the information stored in the release state flag 153 and the last release date 154 of the lock information DB 15.

  The door monitoring unit 214 of the key device 21 monitors the state of the door controlled by the own device (S21). Monitoring is continued until opening is detected (NO in S22). As described above, the door monitoring unit 214 recognizes that the door is opened more than a certain angle, or that the magnet provided on the door and the outer frame is separated as being opened. At this time, the angle recognized as opening may be stored in a storage area (not shown) of the lock device 21 or a storage area of the door monitoring section 214 by a supervisor setting in advance.

  When the door monitoring unit 214 detects opening (S22 YES), the door monitoring unit 214 transmits an open state notification including information indicating that the door is open to the control unit 213, and the control unit 213 transmits an open state notification. Is transmitted to the receiving unit 12 of the door control device 1 (S23). Note that the door monitoring unit 214 may directly instruct the transmission unit 212 to transmit an open state notification. The open state notification includes the lock ID of the lock device 21 together with information indicating that the lock has been released. A lock address may be included instead of the lock ID. Subsequently, the door monitoring unit 214 of the key device 21 monitors until the door including the own device is in an unopened state (S24).

  On the other hand, the receiving unit 11 of the door opening / closing control device 1 receives the open state notification (S11) and passes it to the door opening / closing control unit 13. The door opening / closing control unit 13 reads the lock ID (or lock address) of the lock device 21 from the open state notification, and changes the item “open flag” 153 of the corresponding lock state DB 15 to “1” (S12). At this time, when the lock state DB 15 includes the item “last release date / time” 154, the date / time when the release flag is updated to “1” is stored in the item “last release date / time” 154. Then, the door opening / closing control device 1 stands by (S13).

  For example, the door monitoring unit 214 of the lock device A21 constantly monitors the state of the door controlled by the own device and detects opening. Then, the transmission unit 212 notifies the reception unit 12 of the door control device 1 of the open state notification including the lock ID “A”. The receiving unit 12 of the door opening / closing control device 1 receives the open state notification and passes it to the door opening / closing control unit 13. The door opening / closing control unit 13 reads the lock ID “A” of the lock device A21 from the open state notification, and changes the item “open flag” 153 of the lock state DB 15 corresponding to the lock ID “A” to “1”. Then, the date and time “2009.3.10 12:00:00” when the unlocking flag is updated to “1” is stored in the item “last release date and time” 154. Then, the door opening / closing control device 1 stands by.

  Subsequently, the door monitoring unit 214 of the key device 21 continues monitoring until it detects that the door controlled by the device itself is not opened (S25 NO). For example, it is recognized as non-opening when the angle at which the door is opened is less than a certain value, or when the door is in contact with the magnet provided on the outer frame.

  When non-opening is detected (YES in S25), the door monitoring unit 214 notifies the control unit 213 of a non-opening state notification including information indicating that the door controlled by the device is not open, and the control unit 213 is not open. The transmission unit 212 is instructed to transmit the status notification, and the transmission unit 212 transmits the state notification to the reception unit 11 of the door control device 1 (S26). The door monitoring unit 214 may directly instruct the transmission unit 212 to transmit a non-open state notification. The non-open state notification includes the lock ID and the lock address of the lock device 2. Subsequently, the door monitoring unit 214 of the key device 21 again monitors the state of the door controlled by the own device (S21).

  On the other hand, the receiving unit 12 of the door opening / closing control device 1 receives the notification of the non-open state (S14) and passes it to the door opening / closing control unit 13. The door opening / closing control unit 13 reads the lock ID (or lock address) of the lock device 2 from the non-open state notification, and changes the item “open flag” 153 of the corresponding lock state DB 15 to “0” (S15). And it ends.

  Subsequently, a movement related to each processing unit shown in FIG. 1 will be described with reference to FIG. 5 according to a first embodiment of the present invention. FIG. 5 is a diagram showing a processing flow of door opening / closing control in the first embodiment.

  First, the information providing apparatus 3 detects the occurrence of a disaster by detecting the initial tremor of the earthquake, and the disaster occurrence information including the disaster occurrence scale and the main movement arrival time of the earthquake is sent to the door opening / closing control apparatus 1 via the public line 5. Transmit (S31). The receiving unit 11 of the door opening / closing control device 1 receives the disaster occurrence information (S41) and transfers it to the door opening / closing control unit 13. The door opening / closing control unit 13 reads out the disaster scale, arrival time, and the like from the disaster occurrence information, and acquires the disaster scale threshold by referring to the disaster information DB 14 (S42).

  Then, the door opening / closing control unit 13 compares the acquired disaster threshold value with the disaster scale included in the disaster occurrence information (S43). If the disaster scale is smaller than the disaster scale threshold (NO in S43), the process ends. If the disaster scale is larger than the disaster scale threshold (YES in S43), the door opening / closing control unit 13 refers to the lock information DB 15 and searches for the lock device 21 in the open state (S44). Specifically, the lock device 21 in which “1” is stored in the release flag 153 is searched. If there is no lock device 21 in which “1” is stored in the release flag 153 (NO in S44), the process ends.

  On the other hand, if there is a lock device 21 in which “1” is stored in the release flag 153 in the lock information DB 15, the door opening / closing control unit 13 reads the lock address corresponding to the lock device 21 (YES in S 44). The door opening / closing control unit 13 instructs the transmission unit 12 to transmit a door closing prohibition command, and the transmission unit 12 transmits a door closing prohibition command to the read lock address (S45). The door closing prohibition command is a command for prohibiting the lock device 21 from closing the door.

  For example, a case will be described in which the reception unit 11 receives disaster occurrence information including information “an earthquake with an expected seismic intensity 6”. The door opening / closing control unit 13 reads the disaster scale “seismic intensity 6” from the disaster occurrence information, and acquires the disaster scale threshold “seismic intensity 6” with reference to the disaster information DB 14 (FIG. 2A).

  Since the disaster scale threshold “seismic intensity 6” is equal to or less than the disaster scale “seismic intensity 6”, the door opening / closing control unit 13 refers to the lock information DB 15 (FIG. 3) and detects the lock device 21 in the open state. The door opening / closing control unit 13 refers to the lock information DB 15 and stores “12.34.56.78” stored in the lock address 152 of the lock device “A” in which “1” is stored in the release flag 153. And “90.12.34.56” stored in the lock address 152 of the lock device “E” is read. Then, the transmitting unit 12 transmits a door closing prohibition command to the read lock addresses “12.34.56.78” and “90.12.34.56” (S45).

  On the other hand, the receiving unit 211 of the lock device 21 corresponding to the lock address to which the transmission unit 12 of the door opening / closing control device 1 has transmitted the door close prohibition command receives the door close prohibition command (S51). And the control part 213 which received the door closing prohibition command from the receiving part 211 issues a door closing prohibiting instruction to the lock (S52).

  As described above, when the door is in an open state, if the dead bolt or the latch bolt protrudes, the door can be prevented from being closed without being fitted in the outer frame. Therefore, when the control unit 213 is locked, the dead bolt can be protruded and the dead bolt can be supported by the outer frame. Also, the door can be prevented from being closed in the same manner by causing the control unit 213 to project the lock bolt.

  In this embodiment, the control unit 213 of the lock device 21 performs the process of generating the door closing prohibition instruction. However, the door opening / closing control device 1 may generate the door closing prohibiting instruction to include the door closing prohibiting instruction. .

  For example, the receiving unit 211 of the lock device A21 corresponding to the lock address “12.34.56.78” receives a door closing prohibition command from the door opening / closing control device 1. And the control part 213 locks a lock, makes a dead bolt a protrusion state, and prevents that a door closes.

  From the above configuration, it is possible to specify a door where a person is likely to exist in the vicinity without causing the evacuating person to carry the apparatus as in Patent Document 1. This is because a door is open because there is a high possibility that a person has opened the door to pass there, that is, there is a high possibility that a person exists in the vicinity.

  By controlling the specified door not to close, it is possible to prevent the door from being opened due to the distortion of the building due to the earthquake. And since the door only prevents dead bolts or latch bolts from being completely fitted in the outer frame, the gap through which air can pass is very narrow. Therefore, it is possible to prevent the fire from expanding due to the air flow.

  Furthermore, since it is possible to prevent the door from being closed by the process of projecting the latch bolt or dead bolt of the door in the open state, there is no need to newly provide a device for opening the door as in Patent Document 1, and it is easy. Can secure an evacuation route.

  FIG. 4 has been described as a movement related to each processing unit shown in FIG. 1 before the reception unit 11 of the door opening / closing control device 1 receives the disaster occurrence information, but this process is also performed after receiving the disaster occurrence information (FIG. 5). It is good to do. In that case, each time the door opening / closing control device 1 receives the open state notification of S11 of FIG. 4 after S45 shown in FIG. 5, a door close prohibition command is transmitted to the lock address included in the open state notification. Anyway.

  With this configuration, the door opening / closing control device 1 can also control the lock device 21 that controls the door that is opened during the period from when the disaster occurrence information is received until the main movement arrives. Therefore, it is possible to prevent the door opened during the time from the detection of the initial fine movement to the arrival of the main movement from closing. That is, an evacuation route can be secured by preventing a person who has performed the time from detection of initial fine movement to arrival of main movement from closing a door in the vicinity.

  By the way, measures are taken to suppress the occurrence of danger before the arrival of the main motion of the earthquake using the Earthquake Early Warning of the Japan Meteorological Agency. In other words, after receiving the earthquake early warning, it is considered that the control signal for suppressing the occurrence of danger increases and the load on the communication line increases. Furthermore, there is a possibility that a situation in which various measures cannot be taken before reaching the main movement due to a decrease in the communication speed due to an increase in the load on the communication line. Therefore, we want to avoid sending useless commands that would cause a load on the communication line.

  By the simple process as described above, when the door opening / closing control device 1 receives the disaster occurrence information, it is possible to identify a door that exists in the vicinity and prevent the door from being closed, which is useless. It is possible to avoid unnecessarily increasing the load on the communication line by sending a command.

  A related operation of each processing unit shown in FIG. 1 will be described with reference to FIG. The first embodiment secures an evacuation route by instructing not to close only the door in the open state, but the second embodiment does not close the door opened within a certain time. By doing so, the evacuation route is more reliably secured.

  Since S31 and S61 shown in FIG. 6 are the same as S31 and S41 in FIG. The door opening / closing control unit 13 reads out the disaster scale, occurrence time, and the like from the disaster occurrence information, and acquires the disaster scale threshold and the open time threshold with reference to the disaster information DB 14 (S42).

  Then, the door opening / closing control unit 13 compares the acquired disaster scale threshold with the disaster scale included in the disaster occurrence information (S63). If the disaster scale threshold is larger than the disaster scale (NO in S63), the process ends.

  Subsequently, if the disaster scale threshold is equal to or less than the disaster scale (S63 YES), the door opening / closing control unit 13 calculates a date and time that is backed by the acquired opening time threshold from the reception time of the disaster occurrence information (S64). The door opening / closing control unit 13 refers to the lock information DB 15 to search whether there is a lock device 21 whose final opening date is later than the calculated date (S65). If it does not exist (NO in S65), the process ends.

  When the door opening / closing control unit 13 detects the lock device 2 whose final opening date is later than the calculated date and time (S65 YES), the lock address corresponding to the specified lock device 21 is referred to the lock information DB 15. The lock address stored in 152 is read out, and the transmission unit 12 is instructed to transmit a door closing prohibition command. The transmission unit 12 transmits a door opening / closing prohibiting command to the read lock address (S66).

  For example, a case will be described in which the door opening / closing control apparatus 1 receives disaster occurrence information “March 10, 2009, 12:00:05” “An earthquake with an expected seismic intensity 6 occurs”. Referring to the disaster occurrence time zone 142 of the disaster information DB 14 (FIG. 2B), the disaster scale corresponding to the disaster occurrence time zone “6:00 to 20:00” including the time when the disaster occurrence information is received “Seismic intensity 6” stored in the threshold 141 and “60 seconds” stored in the opening time threshold 143 are acquired.

  Since the disaster threshold “seismic intensity 6” is less than or equal to the disaster scale “seismic intensity 6”, the unlocking time threshold “60 seconds” acquired from the disaster occurrence information reception time “March 10, 2009, 12:00:05” Calculate the date and time that only goes back. The calculation result is “2009/03/10 11:59:05”. The door opening / closing control unit 13 refers to the lock information DB 15 to search whether there is a lock device 21 whose final opening date is later than the calculated date.

  The door opening / closing control unit 13 has a lock address 152 corresponding to the lock devices “A”, “B”, and “E” having a date and time after “March 10, 2009 11:59:05” on the last opening date 154. "12.34.56.78", "34.56.778.90", and "90.12.34.56" stored in. Then, the transmission unit 12 transmits a door closing prohibition command to the read lock addresses “12.34.56.78”, “90.12.34.56”, and “90.12.34.56”. .

  On the other hand, the reception unit 211 of the lock device 21 corresponding to the lock address designated by the transmission unit 12 of the door opening / closing control device 1 receives the door closing prohibition command (S71). And the control part 213 which received the door closing prohibition command from the receiving part 211 issues a door closing prohibiting instruction to the lock (S72). With the door closing prohibition instruction, if the door controlled by the locking device 21 is in an open state, the control unit 213 issues a door closing prohibition instruction for projecting a dead bolt or a latch bolt as in the first embodiment.

  On the other hand, if the door provided with the lock device 21 is in the non-open state, the control unit 213 instructs the lock to unlock, opens the door, and further instructs the door closing prohibition to project the dead bolt or the latch bolt. . In the second embodiment, the lock device 21 needs to include a device that applies a physical force to the door and opens the door. The opening device operates under the control of the control unit 213. And it can prevent that a door closes by making a dead bolt or a latch bolt project before the door opened by the opening | release apparatus fits in an outer frame again.

  For example, the control unit 213 of the locking device “A” and the locking device “E” causes the dead bolt to protrude as a door closing prohibition instruction. On the other hand, the control unit 213 of the locking device “B” instructs the unlocking to store the dead bolt as the door closing prohibiting instruction, opens the door to the opening device, and sets the dead bolt or This is an instruction to project the latch bolt. The door controlled by the locking device “B” is not closed by a series of door closing prohibition instructions.

  Here, it has been described that the control unit 213 of the lock device 21 determines the content of the door close prohibition instruction based on the door close prohibition command, but the content included in the door close prohibition command by the door opening device 1 is indicated by the open state flag. It is good also as changing and producing | generating for every locking apparatus 2, and transmitting.

  With the configuration described above, the door can be prevented from being closed with the lock device 21 having a history of being opened within a certain time as the target of the door opening / closing control process. Therefore, an evacuation route can be ensured more reliably.

  And it can prevent that a door cannot be opened by the distortion of the building by an earthquake by controlling not to close the specified door. The door is supported by dead bolts or latch bolts, and the gap through which the air can pass is very narrow, so it is possible to prevent the fire from spreading due to the flow of air. Further, it is possible to avoid unnecessarily increasing the load on the communication line by transmitting a useless command.

  Furthermore, the conditions for executing the door opening / closing control process can be varied depending on the time period. For example, at midnight when rescue is expected to be delayed, the door opening / closing control process can be executed even when the scale of the disaster is small, or the door that has a history of opening within a longer time is also opened. Can be identified as the target of Therefore, an evacuation route can be secured more reliably.

  The embodiment of the present invention is not limited to the above.

  For example, the door opening / closing control can be performed only by the lock device 21. The receiving unit 211 is connected to the information providing apparatus 3 and receives disaster occurrence information from the information providing apparatus 3. If the door monitoring unit 214 detects the opening of the door when the disaster occurrence information is received, the control unit 213 may project the dead bolt or the latch bolt. That is, the lock device 21 acts as the door opening control device 1.

  With such a configuration, door opening / closing control can be performed by each simple device that does not require a storage unit. For example, the present invention can also be applied to a case where the door is controlled on a small scale by connecting to a door of a residence.

  For example, the door opening / closing control apparatus 1 does not have to include all the processing units illustrated in FIG. 1 on one housing, and one or several processing units are mounted on other computers that are communicably connected to each other. It does not matter.
