Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of a crime prevention system according to Embodiment 1 of the present invention.
This security system is provided in a building having an elevator. In FIG. 1, 1 is an elevator car, 2 is an elevator control panel, and 3 is an elevator scale device.

  The car 1 moves up and down in a hoistway formed in the building. The car 1 is provided with an operation panel 4, an intercom 5, a camera 6, a monitor 7, and a speaker 8.

The operation panel 4 is for operation by passengers in the car 1. The operation panel 4 is provided with, for example, a destination button 9 for each floor where the car 1 stops, a door opening button 10 and a door closing button 11.
The intercom 5 is for a passenger in the car 1 to talk to the outside. The intercom 5 is provided with an emergency call button 12 that is operated by passengers in the car 1 in an emergency. When the emergency call button 12 is pressed, a predetermined emergency signal is transmitted to the communication device 21 described later.

  The camera 6 is provided in the car 1 for the purpose of crime prevention. For example, the field of view and the photographing direction of the camera 6 are appropriately set so that the state (predetermined range) in the car 1 can be photographed. An image in the car 1 photographed by the camera 6 is transmitted to a recorder 18 described later.

  The monitor 7 and the speaker 8 constitute a notification device that notifies various information to passengers in the car 1. During normal operation of the elevator (when normal service is provided), the monitor 7 and the speaker 8 provide predetermined information useful to passengers such as destination floor information, news, and weather forecasts.

  The control panel 2 has a function of controlling the entire elevator including the control of the car 1. The control panel 2 has a function of performing a control operation in accordance with predetermined input information in addition to a normal function (a function of performing a normal operation) that makes the car 1 appropriately respond to calls registered from the elevator hall and the operation panel 4. ing. Reference numeral 13 denotes a car door that opens and closes the entrance of the car 1. A door driving device (not shown) for opening and closing the car door 13 is also controlled by the control panel 2. Detailed functions of the control panel 2 such as the contents of the control operation will be described later.

  The scale device 3 has a function of detecting the loaded load of the car 1. The detection result of the scale device 3 is transmitted to the control panel 2. Any method may be used for the scale device 3 to detect the loaded load.

  Reference numeral 14 denotes a door provided on a predetermined floor of the building. The door 14 is provided on the floor where the car 1 stops, and has a configuration that can be locked by the electric lock 15. The door 14 provided with the electric lock 15 may be provided on a plurality of floors where the car 1 stops. The door 14 is provided in a passage leading from the elevator hall on the installation floor to another floor, an entrance / exit leading to the outside of the building, and the like. That is, the person who gets off the elevator on the floor where the door 14 is installed cannot move out of the other floors or buildings unless it passes through the passage and the entrance / exit provided with the door 14. ing.

  Reference numeral 16 denotes an electric lock control panel for controlling the electric lock 15, that is, locking and unlocking, and 17 is a camera provided outside the car 1. The camera 17 is installed at a predetermined location in a building so that the door 14 can be photographed, for example. An image photographed by the camera 17 is transmitted to the recorder 18.

  The recorder 18 is installed, for example, in the upper part of the car 1 or in the elevator machine room. Images transmitted from the cameras 6 and 17 are sequentially recorded in a predetermined recording unit (not shown) of the recorder 18. The recorder 18 includes an abnormal behavior determination unit 19 and an image input / output control unit 20.

  The abnormal action determination unit 19 has a function of determining whether or not a person in the car 1 is performing an abnormal action based on an image in the car 1 taken by the camera 6. For example, the recorder 18 has preset conditions for determining abnormal behavior. The abnormal behavior determination unit 19 detects abnormal behavior when the result of analyzing the image from the camera 6 satisfies the above condition. And the abnormal action determination part 19 will transmit a predetermined | prescribed detection signal to the below-mentioned communication apparatus 21, if an abnormal action is detected.

  The image input / output control unit 20 has a function of controlling image input / output with respect to the recorder 18. For example, when a predetermined signal is input, the image input / output control unit 20 outputs an image photographed by the camera 6 or 17 or an image registered in advance in the recorder 18 to be displayed on the monitor 7. .

  The communication device 21 controls the entire system. The communication device 21 is connected to, for example, the elevator car 1, the control panel 2, the electric lock control panel 16, and the recorder 18, and is configured to be able to transmit / receive information to / from each other. The communication device 21 is also connected to a monitoring center 23 and a security company 24 outside the building via a predetermined communication network 22.

  The communication device 21 includes a crime prevention determination unit 25, a central processing unit 26, an announcement storage unit 27, and a line control unit 28.

  The crime prevention determination unit 25 has a function of determining whether or not a predetermined crime prevention situation requiring crime prevention (or prevention) has occurred. For example, when an abnormal action is detected by the abnormal action determination unit 19 and the emergency call button 12 is pressed within a predetermined time, the crime prevention determination unit 25 detects the crime prevention situation.

  The central processing unit 26 has a function of appropriately controlling the present system based on the determination result of the crime prevention determination unit 25 and the like. For example, when the crime prevention determination unit 25 detects a crime prevention situation, the central processing unit 26 causes the control panel 2 to start a control operation to rescue the victim in the car 1. The central processing unit 26 controls each of the monitor 7 (image input / output control unit 20), the speaker 8, and the electric lock control panel 16, and transmits / receives information to / from the outside. Note that audio data for making announcements from the speaker 8 is stored in advance in the announcement storage unit 27. Communication with the outside is performed via the line control unit 28.

  Hereinafter, the operation of the crime prevention system (in particular, the communication device 21) will be specifically described with reference to FIGS. 2 and 3 are flowcharts showing the operation of the security system according to Embodiment 1 of the present invention.

  In this crime prevention system, the crime prevention judgment unit 25 of the communication device 21 always judges whether or not an emergency signal has been received from the emergency call button 12 (S1). The communication device 21 does not perform any control necessary for crime prevention unless an emergency signal is received. For this reason, normal operation is performed in an elevator.

  For example, a passenger of an elevator rides in an unmanned car 1 and imitates the swing of golf by thinking that nobody gets in the way. Since the camera 6 is operating at all times (or only when the elevator is operating, or only when there are passengers in the car 1), the movement of this passenger is captured by the camera 6, and the image is sent to the recorder 18. Sent. In the recorder 18, the abnormal behavior determination unit 19 determines the presence or absence of abnormal behavior based on the image from the camera 6. Since the above-described behavior of the passenger is a large operation in the car 1, depending on the setting conditions, the abnormal behavior determination unit 19 may determine that the behavior is abnormal. However, since the crime prevention determination unit 25 does not receive an emergency signal from the emergency call button 12, even if a detection signal is received from the abnormal action determination unit 19, it is not determined that a crime prevention situation occurs. For this reason, the central processing unit 26 selects the normal mode, and the control panel 2 continues the normal operation.

  On the other hand, when receiving an emergency signal from the emergency call button 12 (Yes in S1), the crime prevention determination unit 25 has a predetermined time, for example, 5 seconds immediately before receiving the emergency signal (or 6 seconds including the time when the emergency signal is received). ), It is determined whether a detection signal is received from the abnormal behavior determination unit 19 (S2).

  For example, when the passenger is in the car 1 and the car 1 stops between the floors for some reason, the car door 13 is not opened even if the door opening button 10 is pressed, and the passenger is confined in the car 1. It will be in the state. In such a case, the passenger presses the emergency call button 12 in the car 1 in order to inform the outside that he / she has been trapped. When the emergency call button 12 is pressed, an emergency signal is input to the crime prevention determination unit 25 (Yes in S1).

  It is extremely rare for passengers to rampage when confinement occurs. For this reason, if the crime prevention determination unit 25 receives an emergency signal from the emergency call button 12 and does not receive a detection signal from the abnormal action determination unit 19 (No in S2), the crime prevention determination unit 25 detects the occurrence of confinement, and notifies that effect. The central processing unit 26 is notified. Upon receiving this notification, the central processing unit 26 shifts the system mode from the normal mode to the confinement rescue mode (S3).

Specifically, the central processing unit 26 performs the following processing in the confinement rescue mode.
S3-1: Connect to the monitoring center 23 via the line control unit 28 and the communication network 22, and notify the monitoring center 23 that confinement has occurred.
S3-2: After the notification, the control signal from the monitoring center 23 is relayed and transmitted to the control panel 2 to cause the control panel 2 to perform a rescue operation to rescue the passengers trapped in the car 1.
S3-3: After the passenger is rescued by the rescue operation, a control signal from the monitoring center 23 is relayed and transmitted to the control panel 2, and the control panel 2 is caused to perform a predetermined inspection operation.

  When the central processing unit 26 receives a notification that the inspection operation is completed from the monitoring center 23, the central processing unit 26 disconnects the connected line in S3-1 and returns the system to the normal mode (S4). Thereby, the normal operation is resumed in the elevator.

  On the other hand, when a passenger (victim) in the car 1 is attacked by a passenger (criminal) and presses the emergency call button 12 while resisting, an emergency signal is input to the crime prevention determination unit 25 (Yes in S1). In such a case, since the situation in which the victim or the criminal is exposed is photographed by the camera 6, the abnormal behavior is detected by the abnormal behavior determination unit 19, and the detection signal is input to the crime prevention determination unit 25. For example, if the crime prevention determination unit 25 has received a detection signal from the abnormal behavior determination unit 19 two seconds before receiving the emergency signal (Yes in S2), the crime prevention determination unit 25 detects the crime prevention situation and notifies the central processing unit 26 to that effect. Notify Upon receiving this notification, the central processing unit 26 shifts the system mode from the normal mode to the security rescue mode (S5).

Specifically, the central processing unit 26 performs the following processing in the security rescue mode (S6).
S6-1: A signal for performing a predetermined control operation A is transmitted to the control panel 2 of the elevator. Thereby, the control panel 2 starts the control operation A.
S6-2: A signal for starting a threatening announcement is transmitted to the announcement storage unit 27. As a result, an announcement for threatening the criminal such as “a security guard is coming soon” is output from the speaker 8 in the car 1.
S6-3: A signal for displaying a threatening image is transmitted to the image input / output control unit 20 of the recorder 18. As a result, an image for threatening the criminal such as “an image of a guard running in the building” is displayed on the monitor 7 in the car 1. The threatening image is registered in advance in the recorder 18.
S6-4: Connect to the monitoring center 23 via the line control unit 28 and the communication network 22, and transmit the image captured by the camera 6 to the monitoring center 23 via the recorder 18.

Further, in the control panel 2 of the elevator, the following processing is performed as the control operation A.
S6-1a: Of the floors where the doors 14 having the electric locks 15 are installed, the floor nearest from the current position of the car 1 is automatically registered as the destination floor, and the car 1 travels toward the destination floor.
S6-1b: The information on the automatically registered destination floor is transmitted to the communication device 21.
S6-1c: The loaded load M1 detected by the scale device 3 is read and stored.
S6-1d: After the car 1 arrives at the automatically registered destination floor, the car 1 is opened.
In addition, the process of S6-1b is implemented, for example, immediately after performing automatic registration of the destination floor, and the process of S6-1c is performed before the car 1 is opened.

The control panel 2 further performs the following processing after opening the door on the automatically registered destination floor.
S6-1e: It is determined whether or not the door closing button 11 has been pressed.
S6-1f: When the pressing of the door closing button 11 is detected, the load M2 detected by the scale device 3 is read and stored.
S6-1g: It is determined whether or not the load load M2 is reduced by a predetermined amount (for example, 20 kg) or more than the load load M1 detected in advance. While the control operation A is performed, the monitor 7 and the speaker 8 are informing the threat. For this reason, when M2 has decreased by a predetermined amount or more than M1, it is determined that the criminal got out of the car 1 and the car 1 is closed.

  Control operation A is completed by the series of operations described above. When the control operation A is completed, the control panel 2 shifts to a predetermined control operation B. At this time, the control panel 2 transmits to the communication device 21 a signal to the effect that the control panel 2 shifts to control operation B.

  The communication device 21 (the central processing unit 26 thereof) determines whether or not destination floor information has been received from the control panel 2 after transmitting a transition signal to the control operation A to the control panel 2 in S6-1. S7). When the central processing unit 26 receives destination floor information from the control panel 2 by the process of the control panel 2 in S6-1b (Yes in S7), the central processing unit 26 transmits a predetermined locking signal to the electric lock control panel 16, and the control panel 2 The electric lock 15 provided on the door 14 of the destination floor that has been automatically registered is locked (S8). The central processing unit 26 completes the locking of the electric lock 15 after the condition is satisfied in S2 (Yes is determined) until the condition for closing the door is satisfied in S6-1g. Let

Thereafter, the central processing unit 26 determines whether or not a transition signal from the control panel 2 to the control operation B has been received (S9). And the central process part 26 will perform the following processes, if the transfer signal to control operation B is received from the control panel 2 (S10).
S10-1: An image photographed by the camera 6 in the car 1 and the camera 17 on the floor which is the destination floor in the control operation A is transmitted to the monitoring center 23 via the recorder 18.
S10-2: A signal for displaying an image by the camera 17 on the destination floor is transmitted to the image input / output control unit 20 of the recorder 18. Thereby, the state of the destination floor after the door is closed is displayed on the monitor 7 in the car 1.
S10-3: A signal for starting a call preparation announcement is transmitted to the announcement storage unit 27. As a result, an announcement such as “Preparing for a call with the center. Please wait for a while” is output from the speaker 8 in the car 1.

  When the elevator control panel 2 shifts to control operation B, a predetermined floor other than the floor that is the destination floor in control operation A is automatically registered as the destination floor, and the newly registered destination floor is registered. Drive the car 1 toward you. Then, when the car 1 arrives at the new destination floor, the control panel 2 causes the car 1 to stand by while being closed on the floor. That is, after the car 1 stops on the new destination floor, the elevator can be controlled only by remote control from the monitoring center 23.

  In addition, in the monitoring center 23, when images from the cameras 6 and 17 are transmitted from the communication device 21 by the processing of S10-1, the images are displayed on a monitor in the center to determine whether or not countermeasures are necessary. To do. For example, when the control operation B is performed by the control panel 2, an image in which only the victim is in the car 1 is displayed on the monitor in the center. In such a case, the monitoring center 23 transmits a predetermined signal for starting a call to the communication device 21 in order to make a call with the victim.

  When the communication device 21 (the central processing unit 26 thereof) receives the transition signal to the control operation B in S9, it determines whether or not a call start signal is received from the monitoring center 23 (S11). When receiving the call start signal from the monitoring center 23, the central processing unit 26 stops the announcement of S10-3 that has been continued until then and starts the call operation (S12). Thereby, the victim in the car 1 can talk with the monitoring center 23 (the operator) through the intercom 5.

In the monitoring center 23, after transmitting a call start signal to the communication device 21, appropriate measures corresponding to the situation are taken from the conversation with the victim in the car 1.
For example, if it is determined that a crime has occurred, the monitoring center 23 reports to the security company 24 and urges security guards, police officers, etc. to the scene. When it is confirmed that the person left in the car 1 is a victim, the monitoring center 23 opens the car 1 by remote control. When the conversation with the victim in the car 1 ends, the monitoring center 23 transmits a predetermined signal indicating that the call has ended to the communication device 21.

  The communication device 21 (the central processing unit 26) determines whether or not a call end signal has been received from the monitoring center 23 after starting the call operation in S12 (S13). When receiving the call end signal from the monitoring center 23, the central processing unit 26 ends the call operation by the line control unit 28 (S14).

  Moreover, the guard or police officer who arrived at the site contacts the monitoring center 23, operates the elevator by remote control, and secures the criminal who is confined in the predetermined floor by the control operation A. When the monitoring center 23 receives a report from the security guard or police officer that the on-site response has been completed, the monitoring center 23 transmits a predetermined signal to the communication device 21 to permit recovery.

  The communication device 21 (the central processing unit 26) determines whether or not a recovery permission signal has been received from the monitoring center 23 after terminating the call operation in S14 (S15). When the central processing unit 26 receives the recovery permission signal from the monitoring center 23, the central processing unit 26 transmits the recovery signal to the elevator control panel 2, the recorder 18, and the electric lock control panel 16 (S16), and shifts the system to the normal mode ( S4).

  In the crime prevention system having the above-described configuration, the presence / absence of the crime prevention situation is determined using both the image analysis result and the operation result of the emergency call button 12. For this reason, it is not necessary to prepare an apparatus with extremely high image analysis capability as the recorder 18, and the system can be configured at low cost. Moreover, since the detection is not performed when the crime prevention situation does not occur, useless control operation is not performed, and high reliability can be secured as a system.

  In this security system, when a security situation is detected, a threatening notification is performed, and a door opening operation is performed on a predetermined floor. Therefore, the criminal can be driven out of the car 1 when the door is opened, and the criminal can be quickly separated from the victim. Further, since the electric lock 15 is locked on the floor where the car 1 is stopped, the criminal cannot escape to another floor or outside the building, and there is no fear that the criminal will be missed.

  After the car 1 is opened on the floor, even if the door closing button 11 is operated, the door closing operation is not started unless the load on the car 1 is reduced. For this reason, even if the criminal and the victim are mixed in the car 1 and the door closing button 11 is pressed, or the door closing button 11 is pressed because the criminal may be found by another person, the door closing operation is performed. Never be started. Therefore, it is possible to reliably prevent the victim from being trapped in the car 1 while riding with the criminal. Moreover, since the door open state continues while threatening notification is performed on the floor where the car 1 is stopped, the criminal is easily driven out of the car 1 from this viewpoint.

  Further, in the control operation B, the car 1 is made to stand by in a door-closed state after being moved from the installation floor of the electric lock 15. For this reason, for example, when the person who remains in the car 1 is a criminal, the operator of the monitoring center 23 can take action according to the situation such as not opening the door.

  Note that each device and each function described in the present embodiment are not necessarily configured by one component or device. For example, one function may be constituted by a plurality of parts, or a plurality of functions may be constituted by one part or device.
