(First embodiment)
(Overall structure of the security system)
Please refer to FIG. The security system 1 is provided in a plurality of internal sensors 4a that are installed inside a building 3 built in a monitoring area 2 to be monitored and detect abnormalities on each floor, and in an opening / closing part 6 such as a window or a door of the building 3 Open / close section sensor 4b and an outer periphery sensor 4c for detecting an abnormality in the outer periphery of the building 3. The security system 1 includes a security device 5 connected to the internal sensor 4a, the opening / closing part sensor 4b, and the outer periphery sensor 4c, and a center device 8 installed in the monitoring center 7 and connected to the security device 5 through the communication line NT. Prepare.
Although FIG. 1 shows the case where the building 3 is a three-story building, the number of floors of the building 3 is not limited to the third floor and may be two or more. That is, it may be the second floor or the fourth floor or more.

  Examples of the internal sensor 4a include a sensor that detects a moving body in the room. Moreover, as the outer periphery sensor 4c, the sensor etc. which detect the mobile body of the outer periphery of the building 3 are contained, for example. The internal sensor 4a and the outer periphery 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. Moreover, the internal sensor 4a and the outer periphery sensor 4c may be image sensors that detect the presence or absence of an intruder 9 or the like in the imaging range based on, for example, the difference between the captured image and a normal image stored in advance.

Further, the opening / closing part sensor 4b includes, for example, a sensor for detecting that the opening / closing part 6 is opened, broken or destroyed. The opening / closing part sensor 4b may be, for example, a magnet sensor that detects opening / closing of the opening / closing part.
Hereinafter, the internal sensor 4a, the opening / closing part sensor 4b, and the outer periphery sensor 4c may be collectively referred to as “security sensor 4”.
The security sensor 4 transmits a detection signal to the security device 5 when an abnormality is detected. Communication between the security sensor 4 and the security device 5 is performed by wire or wireless. The security device 5 detects an abnormality that has occurred in the monitoring area 2, for example, an intruder 9 has entered the building 3, based on a detection signal from the security sensor 4.

  The building 3 is provided with an elevator apparatus 10 that carries passengers between multiple 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 the destination floor of the car 11, a door closing button for closing the car door 18 of the car 11, and a door opening button for opening the car door 18.

On the first floor, second floor and third floor landings 13a, 13b and 13c of the building 3, landing operation sections 14a, 14b and 14c are provided, respectively. The hall operating units 14a to 14c may include call buttons for calling the car 11 of the elevator apparatus 10 from the first floor to the third floor, respectively. In addition, landing doors 19a to 19c are provided with landing doors 19a, 19b and 19c for opening and closing 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 floor to the third floor, respectively.
Hereinafter, the landings 13a to 13c may be collectively referred to as “depot 13”, the landing operation units 14a to 14c may be collectively referred to as “depot operation unit 14”, and the landing doors 19a to 19c may be referred to as “depot operation unit 14”. Collectively, it may be described as “Landing door 19”.

The elevator apparatus 10 includes an elevating drive unit 16 that drives the car 11 up and down, and a control box 17 that controls the operation of the elevating drive unit 16 and the braking unit according to the operation 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 a process to be performed by the control box 17 by executing a computer program stored in the storage medium.

The operation mode of the security device 5 includes a security set mode in which an abnormality occurring in the building 3 is notified to the center device 8 when a detection signal is received from the security sensor 4, and a security release that does not notify the center device 8 even if the detection signal is received. It can be set to any of the modes.
Even when the user 20 of the building 3 is in 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, and even if the internal sensor 4a detects the user 20, the abnormality is not reported to the center device 8 while the intruder 9 When an intrusion is detected, an abnormality is reported 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 notify the center device 8 of an abnormality even if it receives a detection signal from the internal sensor 4a on any floor where the user 20 is located. When the detection signal is received from the crime prevention sensor 4, the abnormality is reported to the center device 8.

  Moreover, 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 part 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 the abnormality to the center device 8 even if it receives a detection signal from the internal sensor 4a, and sends a detection signal from the opening / closing unit sensor 4b and the outer circumference sensor 4c. When received, the center device 8 is notified of the abnormality. 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 apparatus 10 can be operated by the hall operation unit 14 to the crime prevention 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 causes the car 11 to wait while the car door 18 remains open on the standby floor where the user 20 should get into the car 11.

For example, a standby floor may be determined in advance. By causing the car 11 to land on the standby floor in advance without waiting for the calling operation by the user 20 when an abnormality occurs, the user 20 is known no matter what floor the car 11 is landing on when the abnormality occurs. You can get into the car 11 from the waiting floor. For this reason, the user 20 does not need to call the car 11 at the hall operating unit 14, and can prevent a delay in evacuation caused by calling the car 11.
In addition, by waiting in a state where the car door 18 remains open, it is possible to prevent a delay in evacuation that takes time from the door opening operation until the car door 18 opens.

Further, 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 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 leaving the car 11 on the floor where the security release mode is set, the car 11 will land on which floor when an abnormality occurs. Even so, the user 20 can get into the car 11 from his / her floor.
Moreover, 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 part 6 are set to the security set mode, the floor on which the internal sensor 4a detects the user 20 may be set as the standby floor. . For example, a floor where the internal sensor 4a has detected the user 20 before the opening / closing part sensor 4b and the outer circumference sensor 4c detect an 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 19 and the car door 18 cannot be opened. As described above, the user 20 can be evacuated from the intruder 9.

The control unit 30 may be an electronic circuit including a CPU and CPU peripheral components such as a ROM and a RAM. The CPU included in the control unit 30 executes a process to be performed by the control unit 30 by executing a computer program stored in the storage medium.

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

When the user authentication fails, the mode setting unit 36 notifies the user that the operation mode shift is not permitted. For example, the display unit 33 outputs a message to the effect that the operation mode transition is not permitted to the user.
When a security set operation that 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 or not the security sensor 4 has detected an abnormality. To do.

When the security sensor 4 detects an abnormality, the mode setting unit 36 does not permit the transition to the security set mode and notifies the user that the transition to the security set mode is not permitted. When the security sensor 4 has not detected an 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 that 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. .
Furthermore, the mode setting unit 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 unit 34.

  In the security set mode, when receiving a detection signal from the sensor, the abnormality determination unit 37 determines whether or not there is an abnormality in comparison with the current mode and the sensor information in the storage unit 35. The abnormality determination unit 37 determines that an abnormality is detected when a detection signal is received from any of various sensors including the security sensor 4 when the security set mode is set.

  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 receives a detection signal from the internal sensor 4a of the floor set to the security release mode. Even if it is received, it is not judged abnormal. In this case, the abnormality determination unit 37 determines that an abnormality has occurred when detection signals are received from the internal sensor 4a, the opening / closing unit sensor 4b, and the outer circumference sensor 4c on floors other than the floor set in the security release mode.

In addition, 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 there is an abnormality even if a detection signal is received from the internal sensor 4a Do not judge. In this case, the abnormality determination unit 37 determines that there is an abnormality when receiving detection signals from the opening / closing unit sensor 4b and the outer circumference sensor 4c.
The abnormality determination unit 37 outputs an internal sensor detection signal indicating a detection result by the internal sensor 4 a to the control box 17 via the communication unit 34.

The notification signal may include information on the identification number of the security device 5, the ID number of the sensor that has detected the abnormality, the type of sensor, and its installation position. In addition, when the abnormality determination unit 37 determines that the abnormality determination unit 37 is abnormal, the notification control unit 38 also outputs an abnormality detection signal to the control box 17.

(Functional configuration of elevator equipment)
Subsequently, the 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 the destination floor of the car 11, a door closing button for closing the car door 18 of the car 11, and a door opening 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 with a communication cable, and an operation instruction is input to the control box 17 by the operation button 40 to the elevator device 10 through communication performed by the operation unit control circuit 41 and the control box 17. Is done.

The hall 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 from the first floor to the third floor, respectively. The operation buttons 42a to 42c are connected to the operation unit control circuits 43a to 43c, respectively. The operation unit control circuits 43a to 43c are connected to the control box 17 housed in the control box 17 via a communication cable, and the operation buttons 42a to 42c are respectively communicated by the operation unit control circuits 43a to 43c and the control box 17. An operation instruction is input to the control box 17 to the elevator apparatus 10 according to 42c.
The control box 17 controls the operation of the elevating drive means 16 based on the information input from the car operating unit 12 and the landing operating units 14a to 14c, and the door opening / closing device 49. And a door opening / closing process for controlling to open and close the car door 18.

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

  In addition, 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, when 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 apparatus 10 to the normal operation mode. Good.

Further, 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 apparatus 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 or not the car 11 is landing on the standby floor where the user 20 of the building 3 should get into the car 11. The waiting floor may be a predetermined floor.
Further, the standby control unit 45 may determine whether or not 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 in the security release mode and the other range is set in 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. You may determine the floor set to. The standby control unit 45 may set the floor set in 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 on which the internal sensor 4a detects the user 20 may be determined based on the signal. The standby control unit 45 may set the floor on which the internal sensor 4a detects the user 20 as the standby floor. For example, the standby control unit 45 may set a floor on which the internal sensor 4a has detected the user 20 before the opening / closing unit sensor 4b and the outer circumference 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 and closing device 49 to open the car door 18 without moving the car 11 from the standby floor. The standby control unit 45 causes the car door 18 to remain on standby.
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 reaches the standby floor, the standby control unit 45 controls the door opening / closing device 49 to open the car door 18. The standby control unit 45 causes the car door 18 to remain on standby.

The car door control unit 46 closes the car door 18 according to the operation of the car operation unit 12 in the crime prevention operation mode. The car door control unit 46 may close the car door 18 when, for example, a door closing button or a destination floor button of the car operation unit 12 is pressed.
The first speed for closing the car door 18 according to the operation of the car operation unit 12 in the crime prevention operation mode may be faster than the second speed for closing the car door 18 in the normal operation mode. That is, when the car door control unit 46 closes the car door 18 according to the operation of the car operation unit 12 in the crime prevention operation mode, the car door control unit 46 closes the car door 18 at the first speed higher than the second speed in the normal operation mode. Also good.

By closing the car door 18 at a high speed in the crime prevention operation mode, the delay in completing the evacuation to the car 11 can be reduced.
If the car door 18 is closed at a high speed, there is a possibility that the user 20 who wants to evacuate to the car 11 is caught in the car door 18. For this reason, the car door control unit 46 may close the car door 18 at the first speed when a button for closing the car door 18 is kept pressed. The button for closing the car door 18 may be, for example, a door closing button included in the car operation unit 12 or a destination floor button.
