FIG. 1 shows a case where the building 3 has three floors. However, the number of floors of the building 3 is not limited to three floors, and may be two or more floors. That is, it may be the second floor or the fourth floor or more.

  The internal sensor 4a includes, for example, a sensor that detects a moving object in a room. In addition, examples of the outer circumference sensor 4c include a sensor that detects a moving body on the outer circumference of the building 3. The internal sensor 4a and the outer peripheral sensor 4c may be infrared sensors that detect the presence or absence of an intruder 9 or the like in the detection range based on, for example, a change in the amount of received infrared light. Further, the internal sensor 4a and the outer peripheral sensor 4c may be image sensors that detect the presence or absence of the intruder 9 or the like in the imaging range based on, for example, a difference between the captured image and a previously stored normal image.

The opening / closing section sensor 4b includes, for example, a sensor for detecting that the opening / closing section 6 is opened, broken or broken. The opening / closing section sensor 4b may be, for example, a magnet sensor that detects opening / closing of the opening / closing section.
Hereinafter, the internal sensor 4a, the opening / closing section sensor 4b, and the outer peripheral sensor 4c may be collectively referred to as a "security sensor 4".
When detecting an abnormality, the security sensor 4 transmits a detection signal to the security device 5. Communication between the security sensor 4 and the security device 5 is performed by wire or wirelessly. The security device 5 detects an abnormality that has occurred in the monitoring area 2 based on a detection signal from the security sensor 4, for example, an intruder 9 entering the building 3.

  The building 3 is provided with an elevator device 10 that carries passengers between a plurality of floors. The elevator apparatus 10 includes a car 11 that can move up and down the hoistway. A car operation unit 12 for operating the elevator is provided inside the car 11. The car operation unit 12 may include, for example, a destination floor button for registering a destination floor of the car 11, a door close button for closing the car door 18 of the car 11, and a door open button for opening the car door 18.

The landings 13a, 13b, and 13c on the first, second, and third floors of the building 3 are provided with landing operating units 14a, 14b, and 14c, respectively. The hall operating units 14a to 14c may include call buttons for calling the car 11 of the elevator apparatus 10 to the first to third floors, respectively. The landings 13a to 13c are provided with landing doors 19a, 19b, and 19c that open and close the entrances of the landings 13a to 13c, respectively. The landing doors 19a to 19c open and close in conjunction with the car door 18 when the car 11 is at the landing position on the first to third floors, respectively.
Hereinafter, the landings 13a to 13c may be collectively referred to as “the landing 13”, the landing operation units 14a to 14c may be collectively referred to as the “landing operation unit 14”, and the landing doors 19a to 19c may be referred to. They may be collectively referred to as “hall door 19”.

The elevator apparatus 10 includes an elevator drive unit 16 that drives the elevator 11 up and down, and a control box 17 that controls the operations of the elevator drive unit 16 and the braking unit in accordance with the operations of the car operation unit 12 and the landing operation unit 14. ing.
The control box 17 may be an electronic circuit including a CPU (Central Processing Unit) and CPU peripheral components such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The CPU provided in the control box 17 executes processing to be performed by the control box 17 by executing a computer program stored in a storage medium.

The operation mode of the security device 5 includes a security set mode for notifying the center device 8 of an abnormality occurring in the building 3 when a detection signal is received from the security sensor 4 and a security release for not reporting the abnormality to the center device 8 even when the detection signal is received. It can be set to any of the modes.
Further, even when the user 20 of the building 3 is inside the building 3, the security set mode may be set for a part of the building 3. In this case, the security release mode is partially set in the location range of the user 20 so that even if the internal sensor 4 a detects the user 20, the abnormality is not reported to the center device 8, and When the intrusion is detected, an abnormality is notified to the center device 8.

  For example, only one of the floors may be set to the security release mode, and the other range may be set to the security set mode. The floor on which the security release mode is set may be, for example, the floor where the user 20 is located. When such an operation mode is set, for example, the security device 5 does not report an abnormality to the center device 8 even if it receives a detection signal from any of the internal sensors 4a on any floor where the user 20 is located. When the detection signal is received from the security sensor 4, the abnormality is notified to the center device 8.

  Alternatively, only the inside of the building 3 may be set to the security release mode, and the outer periphery of the building 3 and the opening / closing unit 6 may be set to the security set mode. When such an operation mode is set, for example, the security device 5 does not report an abnormality to the center device 8 even when receiving a detection signal from the internal sensor 4a, and outputs a detection signal from the opening / closing portion sensor 4b and the outer peripheral sensor 4c. Upon reception, an abnormality is notified to the center device 8. The security device 5 also outputs an abnormality detection signal to the control box 17 when notifying the center device 8 of an abnormality that has occurred in the building 3.

The control box 17 that has received the abnormality detection signal switches the operation mode of the elevator apparatus 10 from the normal operation mode in which the elevator operation unit 10 can be operated by the hall operating unit 14 to the security operation mode in which the car 11 is used as an evacuation space. .
When the operation mode is switched to the crime prevention operation mode, the control box 17 makes the car 11 stand by with the car door 18 kept open on the waiting floor where the user 20 should get into the car 11.

For example, the standby floor may be determined in advance. In the event of an abnormality, the car 11 is landed on the standby floor in advance without waiting for the call operation by the user 20, so that the user 20 can know a known floor regardless of which floor the car 11 is in when the abnormality occurs. The car 11 can be boarded from the standby floor. Therefore, the user 20 does not need to call the car 11 at the hall operating unit 14, and it is possible to prevent evacuation delay caused by calling the car 11.
Further, by making the car door 18 stand by in the open state, it is possible to prevent a delay in evacuation, which occurs from the door opening operation to the opening of the car door 18.

When only one of the floors is set in the security release mode and the other range is set in the security set mode, the floor on which the security release mode is set may be set as the standby floor. Since the security release mode may be set on the floor where the user 20 is located, by keeping the car 11 on standby on the floor where the security release mode is set, the car 11 will land on which floor when an abnormality occurs. The user 20 can get on the car 11 from his / her own floor.
When only the inside of the building 3 is set to the security release mode and the outer periphery of the building 3 and the opening / closing unit 6 are set to the security set mode, the floor where the internal sensor 4a detects the user 20 may be set as the standby floor. . For example, the floor where the internal sensor 4a has detected the user 20 before the opening / closing section sensor 4b and the outer circumference sensor 4c detect the abnormality may be set as the standby floor.

  After the user 20 gets into the car 11, the control box 17 closes the car door 18 according to the operation of the car operation unit 12. On the other hand, the control box 17 invalidates the operation of the hall operating unit 14. As a result, even if the intruder 9 operates the hall operating unit 14, the car 11 cannot be called or the hall doors 19 and 18 cannot be opened. As described above, the user 20 can be evacuated from the intruder 9.

  The mode setting unit 36 determines whether the user who inputs the operation of the operation unit 32 is a registered user in advance. For this purpose, the mode setting unit 36 checks whether or not the user ID information acquired from the operation unit 32 matches the information registered in the registered authentication information in the storage unit 35 in advance. If they match, the user is authenticated as having a right to operate as a valid user (user right), and the setting of the operation mode of the security device 5 by operation input through the operation unit 32 is accepted.

If the authentication of the user fails, the mode setting unit 36 notifies the user that the operation mode is not allowed to be changed. For example, the display unit 33 outputs a message to the effect that the user is not permitted to change the operation mode.
When a security set operation, which is a switching operation for switching the operation mode of the security device 5 from the security release mode to the security set mode, is performed, the mode setting unit 36 determines whether the security sensor 4 has detected an abnormality. I do.

When the security sensor 4 detects an abnormality, the mode setting unit 36 does not permit the shift to the security set mode, and notifies the user that the shift to the security set mode is not permitted. If the security sensor 4 has not detected any abnormality, the mode setting unit 36 shifts the operation mode of the security device 5 to the security set mode.
When a security release operation, which is a switching operation for switching the operation mode of the security device 5 from the security set mode to the security release mode, is performed, the mode setting unit 36 shifts the operation mode of the security device 5 to the security release mode. .
Further, the mode setting section 36 outputs a mode setting signal indicating the setting state of the operation mode of the security device 5 to the control box 17 via the communication section 34.

  In the security set mode, when receiving the detection signal from the sensor, the abnormality determination unit 37 compares the current mode and the sensor information in the storage unit 35 to determine whether there is an abnormality. The abnormality determination unit 37 determines that an abnormality has occurred when a detection signal is received from any of various sensors including the security sensor 4 in the security set mode.

  When only one of the floors of the building 3 is set to the security release mode and the other range is set to the security set mode, the abnormality determination unit 37 outputs a detection signal from the internal sensor 4a of the floor set to the security release mode. Even if received, it is not determined to be abnormal. In this case, the abnormality determination unit 37 determines that an abnormality has occurred when receiving a detection signal from the internal sensor 4a, the opening / closing unit sensor 4b, and the outer circumference sensor 4c on a floor other than the floor set to the security release mode.

When only the inside of the building 3 is set to the security release mode and the outer periphery of the building 3 and the opening / closing unit 6 are set to the security set mode, the abnormality determination unit 37 determines that the abnormality is abnormal even when receiving the detection signal from the internal sensor 4a.

In addition, the notification control unit 38 also outputs an abnormality detection signal to the control box 17 when the abnormality determination unit 37 determines that there is an abnormality.

(Functional configuration of elevator device)
Subsequently, a functional configuration of the elevator apparatus 10 will be described. Please refer to FIG. The car operation unit 12 includes an operation button 40 and an operation unit control circuit 41. The operation buttons 40 may include, for example, a destination floor button for registering a destination floor of the car 11, a door close button for closing the car door 18 of the car 11, and a door open button for opening the car door 18.
The operation button 40 is connected to the operation unit control circuit 41. The operation unit control circuit 41 is connected to the control box 17 by a communication cable, and an operation instruction to the elevator apparatus 10 by the operation button 40 is input to the control box 17 by communication performed by the operation unit control circuit 41 and the control box 17. Is done.

The landing operation units 14a to 14c on each floor include operation buttons 42a to 42c and operation unit control circuits 43a to 43c, respectively. The operation buttons 42a to 42c may include call buttons for calling the car 11 of the elevator apparatus 10 to the first to third floors, respectively. The operation buttons 42a to 42c are connected to operation unit control circuits 43a to 43c, respectively.

An operation instruction is input to the control box 17 to the elevator apparatus 10 by 42c.
The control box 17 controls the operation of the elevating drive unit 16 based on information input from the car operating unit 12 and the landing operating units 14a to 14c to move the car 11 up and down. And a door opening / closing process for opening / closing the car door 18 under control.

Further, the control box 17 includes an operation mode switching unit 44, a standby control unit 45, a car door control unit 46, an operation invalidating unit 47, and a reversing control unit 48.
The control box 17 receives an abnormality detection signal from the security device 5 by a communication unit (not shown). When the control box 17 receives the abnormality detection signal, the operation mode switching unit 44 switches the operation mode of the elevator apparatus 10 from the normal operation mode to the security operation mode.

  Further, the operation mode switching unit 44 switches the operation mode of the elevator apparatus 10 from the crime prevention operation mode to the normal operation mode when a predetermined release condition is satisfied. For example, if the operation mode switching unit 44 determines that the security device 5 has been set to the security release mode based on the mode setting signal received from the security device 5, the operation mode switching unit 44 may switch the operation mode of the elevator device 10 to the normal operation mode. Good.

In addition, for example, the operation mode switching unit 44 may automatically switch the operation mode of the elevator apparatus 10 to the normal operation mode when the car operation unit 12 and the landing operation units 14a to 14c are not operated for a certain period of time.
Further, for example, the operation mode switching unit 44 may automatically switch the operation mode of the elevator device 10 to the normal operation mode when receiving a release signal output from the security device 5 based on an instruction from the center device 8. Good.

When the operation mode is switched to the crime prevention operation mode, the standby control unit 45 determines whether the car 11 has landed on the standby floor at which the user 20 of the building 3 is to enter the car 11. The standby floor may be a predetermined floor.
Further, the standby control unit 45 may determine whether the security release mode is partially set based on the mode setting signal received from the security device 5.

When only one of the floors is set to the security release mode and the other range is set to the security set mode, the standby control unit 45 determines the security release mode based on the mode setting signal received from the security device 5. May be determined. The standby control unit 45 may set the floor set to the security release mode as the standby floor.
When only the inside of the building 3 is set to the security release mode and the outer periphery of the building 3 and the opening / closing unit 6 are set to the security set mode, the standby control unit 45 detects the internal sensor received from the security device 5. The floor at which the internal sensor 4a has detected the user 20 may be determined based on the signal. The standby control unit 45 may set the floor where the internal sensor 4a detects the user 20 as the standby floor. For example, the standby control unit 45 may set the floor where the internal sensor 4a detects the user 20 before the opening / closing unit sensor 4b and the outer periphery sensor 4c detect an abnormality as the standby floor.

When the car 11 has already landed on the standby floor, the standby control unit 45 controls the door opening / closing device 49 and opens the car door 18 without moving the car 11 from the standby floor. The standby control unit 45 causes the car door 18 to be in a standby state in an open state.
When the car 11 is landing on a floor other than the standby floor, the standby control unit 45 moves the car 11 to the standby floor. When the car 11 arrives at the standby floor, the standby control unit 45 controls the door opening and closing device 49 to open the car door 18. The standby control unit 45 causes the car door 18 to be in a standby state in an open state.

The car door control unit 46 closes the car door 18 in response to the operation of the car operation unit 12 in the security operation mode. The car door control unit 46 may close the car door 18 when, for example, a door close button or a destination floor button of the car operation unit 12 is pressed.
The first speed at which the car door 18 is closed in response to the operation of the car operation unit 12 in the security operation mode may be faster than the second speed at which the car door 18 is closed in the normal operation mode. That is, the car door control unit 46 closes the car door 18 at the first speed that is faster than the second speed in the normal operation mode when closing the car door 18 in response to the operation of the car operation unit 12 in the security operation mode. Is also good.

By closing the car door 18 at high speed in the security operation mode, it is possible to reduce a delay in completing the evacuation to the car 11.
When the car door 18 is closed at a high speed, there is a possibility that the user 20 trying to evacuate to the car 11 is pinched by the car door 18. For this reason, the car door control unit 46 may close the car door 18 at the first speed when the button for closing the car door 18 is kept pressed. The button for closing the car door 18 may be, for example, a door close button included in the car operation unit 12 or a destination floor button.

  The reversal control unit 48 performs reversal control for reversing and opening the car door 18 when a predetermined reversal condition is satisfied during the closing of the car door 18. For example, the inversion control unit 48 may invert the car door 18 and open it when detecting an object that comes into contact with the car door 18 in the middle of closing. Further, for example, the inversion control unit 48 may invert the car door 18 and open the car door 18 when detecting an object on the track of the car door 18 being closed. Further, for example, when the hall operating unit 14 of the floor on which the car 11 is landing is operated, the car door 18 may be inverted and opened.
