According to the present invention, in addition to the operation of the invention described in claim 2 or 3, the present invention is adapted to an automatic door that opens and closes by detecting the presence or absence of a person. Although it is necessary to newly install a driving means for opening the door, if it is an automatic door, the driving means is installed in advance, so that is not necessary.

  According to the present invention, since the door is opened only when there is a person in the building even if an earthquake occurs, it is not necessary to open the door when absent, and security can be ensured.

Hereinafter, an embodiment of a door control device embodying the present invention will be described with reference to FIGS.
FIG. 1 is a schematic configuration diagram of an electric automatic door 1. The electric automatic door 1 includes a door frame 3 attached to a building 2 and two sliding doors (sliding movable type) doors 4 and 5 movable within the range of the door frame 3. A driving pulley 6 and a driven pulley 7 are disposed above the doors 4 and 5 at positions facing each other, and a chain 8 is hung between these pulleys 6 and 7. Further, a door drive motor 9 as a drive means serving as a drive source for the doors 4 and 5 is disposed in the vicinity of the drive pulley 6, and an output shaft 9 a of the door drive motor 9 is connected to the drive pulley 6 via a belt 10. ing.

  A moving rail 11 extending along the moving direction of the doors 4 and 5 (left-right direction in FIG. 1) is disposed on the side wall of the building 2 above the doors 4 and 5. Each door 4, 5 is suspended from the moving rail 11 via a pair of left and right hanging door portions 12, 13. Moreover, one (right side in FIG. 1) of the door 12 of the door 4 is attached to the upper chain 8, and one (left side of FIG. 1) of the door 13 of the door 5 is attached to the lower chain 8. . On the floor surface of the building 2, a guide rail 14 that guides the lower ends of the doors 4 and 5 is disposed so as to extend in the left-right direction.

  For example, when the doors 4 and 5 are opened, the door drive motor 9 rotates forward, the chain 8 rotates in the direction of arrow A in FIG. 1, and the doors 4 and 5 move along the moving rail 11 and the guide rail 14. To move away from each other. On the other hand, when the doors 4 and 5 are closed, the door drive motor 9 rotates in the reverse direction and the chain 8 rotates in the direction of arrow B in FIG. 1 so that the doors 4 and 5 move along the moving rail 11 and the guide rail 14. Move closer.

  On the side wall of the building 2, a plurality of door position detection switches 15 serving as closing detection means are arranged above the doors 4 and 5 along the moving direction of the doors 4 and 5. The door position detection switch 15 is constituted by a reed switch, for example, and outputs a door detection signal Spl (see FIG. 4) when the doors 4 and 5 are detected. Further, electric locks 16 and 16 for electrically managing locking / unlocking are attached to the doors 4 and 5, respectively. The electric lock 16 has a lock portion 16a that can protrude on the door side. When the doors 4 and 5 are fully closed, the lock portion 16a protrudes on the door side to lock the doors 4 and 5 and open the doors 4 and 5. The lock portion 16a is retracted to the opposite door side to unlock the doors 4 and 5.

  FIG. 2 is a side view of the electric automatic door 1. An outdoor person detection sensor 17 is attached to the upper part of the outer wall surface of the building 2, and an indoor person detection sensor 18 is attached to the upper part of the inner wall surface of the building 2. These human detection sensors 17 and 18 are sensors that detect the presence or absence of a person within the detection range, and output a door opening signal (H signal) Sop when there is a person within the detection range, and there is no person within the detection range. Sometimes no signal is output. In addition, an alarm 19 that can be notified by voice, warning sound, or the like is installed in the room (inner wall) of the building 2. The outdoor person detection sensor 17 constitutes an entrance / exit management means and an outdoor person detection means, and the indoor person detection sensor 18 constitutes an entrance / exit management means and an indoor person detection means.

  As shown in FIGS. 1 and 2, on the side wall of the building 2, an outdoor smart antenna 20 is disposed on the outer wall surface, and an indoor smart antenna 21 is disposed on the inner wall surface. These smart antennas 20 and 21 have transmission antennas 20a and 21a and reception antennas 20b and 21b, respectively, and output request signals Sre from the transmission antennas 20a and 21a to the communication ranges E1 and E2, respectively. Signal exchange with the smart key 22 is possible. The reason why the smart antennas 20 and 21 are arranged outdoors and indoors is to enable the smart system to be used both indoors and outdoors. The smart antennas 20 and 21 constitute entrance / exit management means and reception means.

  When the smart key 22 receives the request signal Sre from the smart antennas 20 and 21, the smart key 22 outputs a smart signal Sid as an ID signal on which an ID code unique to the key is placed. The smart antennas 20 and 21 can receive the smart signal Sid from the smart key 22 with the receiving antennas 20b and 21b. The smart key 22 includes a key only for personal authentication and a vehicle key having a vehicle door lock unlocking function and the like. When the smart key 22 is used for a vehicle, if the ID code of the smart key 22 matches the ID code registered in the vehicle, the door lock is unlocked or the engine is allowed to start just by approaching the vehicle.

  As shown in FIG. 1, an earthquake sensor 23 is embedded in the ground near the building as an earthquake detecting means for detecting the seismic intensity of the earthquake. The earthquake sensor 23 is arranged in the ground so that the vibration of the door itself when opening and closing and the vibration of a car running in the vicinity are mistakenly detected as an earthquake. The earthquake sensor 23 includes three acceleration sensors 23a to 23c. The acceleration sensor 23a detects the north-south component seismic intensity, the acceleration sensor 23b detects the east-west seismic intensity, and the acceleration sensor 23c detects the vertical component seismic intensity. To do. And these acceleration sensors 23a-23c output the detection signal Str shown in FIG. 3 according to a vibration value.

  By the way, as an earthquake shake, first, a P-wave (Primary-Wave) that shakes in the vertical direction with respect to the ground is generated, and then an S-wave (Secondary-Wave) that is felt as a transverse wave is generated. The P wave is felt as a relatively small shaking, and the S wave is felt as a large shaking. The period from the beginning of the P wave to the beginning of the S wave is called the initial fine movement, and the large movement caused by the S wave is called the main movement. In addition, the detection signal Str in the main motion has a large waveform for all of the north-south component, the east-west component, and the vertical component, whereas the initial fine motion has a large waveform only in the vertical component.

  FIG. 4 is a block diagram showing an electrical configuration of the electric automatic door 1. The electric automatic door 1 includes a controller unit 24 that performs main control of the automatic door. The door position detection switch 15, the outdoor person detection sensor 17, the indoor person detection sensor 18, and the earthquake sensor 23 are connected to the input side of the controller unit 24, and the door drive motor 9, the electric lock 16 and the alarm 19 are connected to the output side. Has been. Further, the controller unit 24 is connected to a power source 25 provided in the building 2.

  The controller unit 24 includes a controller 26 that performs opening / closing control of the doors 4 and 5 and alarm 19 notification control, and a smart controller 27 that manages smart functions. The controller 26 includes a CPU, ROM, RAM, EEPROM, input / output circuits (all not shown), and the like. Based on detection signals from the door position detection switch 15 and various sensors 17, 18, and 23, the door drive motor 9 and the electric lock 16. To control the opening and closing of the doors 4 and 5, or to perform the alarm control by the alarm 19. The controller 26 constitutes control means and door opening / closing control means, and the smart controller 27 constitutes entry / exit management means and verification means.

  Here, the opening / closing operation of the doors 4 and 5 will be described. When a person enters the building 2, the outdoor person detection sensor 17 first detects the person and outputs a door opening signal Sop. The controller 26 unlocks the electric lock 16 using the door opening signal Sop as a trigger, rotates the door driving motor 9 forward, and opens the doors 4 and 5. When a person enters the building 2 and both the person detection sensors 17 and 18 no longer detect the person, the controller 26 inputs an L signal from each of the person detection sensors 17 and 18 and uses it as a trigger to drive the door drive motor 9. Are reversed, the doors 4 and 5 are closed, and the electric lock 16 is locked when the doors are fully closed. On the other hand, when a person leaves the building 2, the point that the indoor person detection sensor 18 detects the person is different from that at the time of entering the room.

  Based on the door detection signal Spl from the door position detection switch 15, the controller 26 manages the positions of the doors 4 and 5 when opening and closing. That is, when opening the doors 4 and 5, when the controller 26 determines that the doors 4 and 5 are approaching the door based on the door detection signal Spl from the door position detection switch 15, the controller 4 decelerates the doors 4 and 5 and opens the doors. Stop near the hit. When the doors 4 and 5 are closed, the controller 26 decelerates the doors 4 and 5 when it determines that the doors 4 and 5 are approaching the fully closed state based on the door detection signal Spl from the door position detection switch 15. Stop at the fully closed position.

  Further, smart antennas 20 and 21 are connected to the input side of the smart controller 27, and the controller 26 is connected to the output side. The smart controller 27 includes a CPU, a RAM, an EEPROM, a transmission / reception circuit (all not shown), and the like. The smart controller 27 can intermittently output the request signal Sre from the transmitting antennas 20a and 21a of the smart antennas 20 and 21, and can interpret the ID code of the smart signal Sid received by the receiving antennas 20b and 21b.

  In the EEPROM of the smart controller 27, the ID codes of the householders (for the whole family) of the building 2 are registered. This ID code can be changed in setting such as erasing / resetting by operating various buttons of the smart key 22, for example. When the smart controller 27 receives the smart signal Sid from the outside, the smart controller 27 compares the ID code with the registered ID code to perform code verification, and outputs a verification result signal Srs corresponding to the verification result to the controller 26. . The controller 26 recognizes which householder is in the building 2 based on the verification result signal Srs.

  The controller 26 performs housekeeping management based on the human detection order of the human detection sensors 17 and 18 and the code collation result by the smart controller 27 to determine who is in the building 2. That is, if the human detection order is the outdoor person detection sensor 17 and the indoor person detection sensor 18, the controller 26 determines that the flow of the person is entering the room, and if the human detection order is the reverse, the flow of the person is leaving the room. A certain judgment is made, and based on the judgment result, based on the collation result by the smart controller 27, it is judged which household has entered or left the room.

  More specifically, when an occupant enters the room, the outdoor person detection sensor 17 detects the occupant and the doors 4 and 5 are opened, and the indoor occupant detection sensor 18 subsequently detects the occupant as the occupant enters the room. . At this time, since the detection order of the person is the order of the outdoor person detection sensor 17 and the indoor person detection sensor 18, the controller 26 determines that the movement of the person is entering the room based on the detection order. Then, the controller 26 receives the verification result signal Srs from the smart controller 27, recognizes the person whose code verification matches when the doors 4 and 5 are open, and determines that the householder has entered the building 2. .

  When the housekeeper leaves the room, the indoor person detection sensor 18 detects the housekeeper and the doors 4 and 5 are opened, and the outdoor person detection sensor 17 detects the housekeeper as the housekeeper leaves the room. Therefore, the controller 26 determines that the movement of the person is leaving the room based on this person detection order. Then, the controller 26 recognizes the person whose code verification is the same as the housekeeper when the doors 4 and 5 are in the open state, and determines that the housekeeper has left the building 2. The same applies to the case where a plurality of householders enter or leave the room with a single door opening operation.

  Further, the controller 26 measures the values of the north-south component, the east-west component, and the vertical component based on the detection value output from the earthquake sensor 23, and determines whether or not an earthquake has occurred and the seismic intensity. When the controller 26 detects initial tremor and determines that an earthquake has occurred, the controller 26 determines whether or not there is a householder in the building 2. When the controller 26 determines that there is a housekeeper in the building 2, the controller 26 starts the opening operation of the doors 4 and 5. When the controller 26 determines that there is no housekeeper in the building 2, the doors 4 and 5 are left closed. .

  Now, when an earthquake occurs, initial tremors in which the vertical component swings larger than the north-south component and the east-west component occur prior to the main motion felt as a large shake. When the controller 26 detects this initial tremor, it determines that an earthquake has occurred, and determines whether there are any householders in the building 2. The controller 26 recognizes which householders are in the building 2 based on the detection results of the human detection sensors 17 and 18 and the personal authentication result of the smart controller 27. Therefore, when an earthquake occurs, the controller 26 opens the doors 4 and 5 if there are occupants in the building 2 and keeps the doors 4 and 5 closed if there are no occupants.

  In this example, even if an earthquake occurs, the doors 4 and 5 are opened (unlocking the electric lock 16 and opening the doors 4 and 5) only when a house occupant is in the building 2. By the way, when an earthquake occurs, the doors 4 and 5 are opened every time, and the doors 4 and 5 are opened even in the case where there are no occupants in the building 2. May occur. However, in this example, since the doors 4 and 5 are opened only when the resident is in the building 2, the doors 4 and 5 are not opened unnecessarily, and security against theft and the like is improved.

According to the electric automatic door 1 of this example, the following effects can be obtained.
(1) Even if the doors 4 and 5 are opened by an earthquake, the doors 4 and 5 are opened only when there are occupants in the building 2. Therefore, if the doors 4 and 5 are opened when no occupants are present, theft However, such a problem does not occur and the security can be improved.

  (2) Based on the detection results of the outdoor person detection sensor 17 and the indoor person detection sensor 18, it is determined whether the flow of the person is entering or leaving the room, and the person who passes through the doors 4 and 5 when entering or leaving the room is managed by smart authentication. Yes. Therefore, it is possible to judge how many (who) have passed even if multiple householders pass through the doors 4 and 5 by a single door opening operation or door closing operation, and perform accurate entrance / exit management. Can do.

(3) When the smart key 22 also serves as a vehicle key, the key can be shared for residential use and for vehicle use.
(4) The configuration of this example is adopted in the electric automatic door 1 that automatically detects the presence or absence of a person by the human detection sensors 17 and 18 and automatically opens and closes the doors 4 and 5. Therefore, for example, if the configuration of this example is adopted for a manual door, it is necessary to newly install an actuator for opening the doors 4 and 5 when an earthquake occurs. Since it is already installed, there is no need to newly install this kind of actuator.

  (5) Since the electric automatic door 1 is configured to lock the doors 4 and 5 with the electric lock 16 each time the doors 4 and 5 are closed, the doors 4 and 5 are always in the fully closed state. 5 becomes locked, contributing to security enhancement such as suspicious person intrusion prevention.

In addition, the said embodiment is not restricted to said structure, You may change into the following aspects.
-The opening operation start timing of the doors 4 and 5 is not limited to when initial fine movement is detected. For example, if the building 2 is close to the epicenter, there is almost no time difference between the P wave and S wave, and there may be a sudden tremor in the three axes on the north, south, north, east, and west. The doors 4 and 5 may be opened when the shaking is detected (that is, when a strong P wave is detected).

  -An automatic door is not limited to what the doors 4 and 5 open and close based on the human detection result by the human detection sensors 17 and 18. FIG. For example, as shown in FIG. 5, the building 2 may be provided with an opening button 41 and a closing button 42, and the doors 4 and 5 may be opened and closed by operating these buttons 41 and 42. The door opening button 41 and the door closing button 42 need to be installed both indoors and outdoors. Moreover, the structure which used the human detection sensors 17 and 18 and the door opening button together may be sufficient as an automatic door. For example, as shown in FIG. 6, human detection sensors 17 and 18 and an opening button 41 are installed in the building 2, the doors 4 and 5 are opened with the opening button 41, and the doors 4 and 5 are closed. It may be performed based on the human detection result of the detection sensors 17 and 18. The door opening button 41 only needs to be installed at least outdoors.

  ・ Household entry / exit management is not limited to using smart systems. For example, as shown in FIG. 6, home buttons (entrance / exit management means) 43 to be pushed when entering the room are installed in the building 2 for the number of the householders, and the home button management is performed by managing the switch state of the home button 43. May be.

・ The personal authentication method is not limited to smart systems. For example, a method may be used in which a fingerprint sensor is installed in the building 2 to determine whether or not the person is a house based on the result of fingerprint matching.
The entrance / exit management is not limited to the configuration in which the human detection sensors 17 and 18 determine the flow of the person, and the smart system determines whether the person entering or leaving the house is a housekeeper. For example, the outdoor smart antenna 20 and the outdoor smart antenna 21 are arranged at positions where signals do not interfere with each other. When the smart signal Sid is received by the outdoor smart antenna 20 and is no longer received by the smart antenna 21 in the room, it is determined that the user has entered the room. In this way, entrance / exit management may be performed using only the smart system.

  ・ Entrance / exit management is not necessarily limited to using smart systems. For example, if it is a door that enters and exits one by one in order, entry / exit may be managed based on the order of person detection by the outdoor person detection sensor 17 and the indoor person detection sensor 18. That is, when the person detection order is the outdoor person detection sensor 17 and the indoor person detection sensor 18, it is determined that there is an entry, and when the person detection order is the indoor person detection sensor 18 and the outdoor person detection sensor 17, it is determined that there is a room exit. It is good.

-Not only the structure which opens and closes the two doors 4 and 5 with one door drive motor 9, but you may open and close each door 4 and 5 with an individual door drive motor, respectively.
-The automatic door is not limited to the electric automatic door 1, but for example, a pneumatic type that sends and receives pressure air from a pressure pump (driving means) to open and close the doors 4 and 5 or a hydraulic pump (driving means) that drives the cylinder It may be a hydraulic type that sends oil to open and close the doors 4 and 5.

  The doors 4 and 5 of the building 2 are not limited to automatic doors, and may be manual doors that are manually opened and closed. In this case, it is necessary to newly install an actuator (driving means) that automatically opens the doors 4 and 5 when an earthquake occurs.

The smart antennas 20 and 21 do not need to be installed both indoors and outdoors, and only one smart antenna may be used according to the ease of passing signals on the side walls of the building 2 and the doors 4 and 5.
The outdoor and indoor person detection means is not limited to the outdoor person detection sensor 17 and the indoor person detection sensor 18 that detect the presence or absence of a person by light or infrared rays. For example, a load sensor may be provided on the floor of the building 2 and the presence or absence of a person may be detected by the load.

The door is not limited to the sliding door type doors 4 and 5, but may be an open type, for example.
Next, a technical idea that can be grasped from the above embodiment and another example will be added below.
