Embodiment 1.
The elevator security system according to the present embodiment will be described with reference to FIGS. 1 to 9.

FIG. 1 is a configuration diagram of an elevator security system according to the first embodiment. This security system is provided in buildings, buildings, etc. that have elevators. In FIG. 1, 1 is an elevator car, 2 is an elevator control device that controls the raising and lowering of the car 1, and 3 is an autonomous mobile robot.

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

The operation panel 4 is for being operated by passengers in the car 1. On the operation panel 4, for example, a destination button 9 for each destination floor on which the car 1 stops, a door open button 10 for opening the door of the car 1, and a door close button 11 for closing the door of the car 1 are provided. Is provided.

The intercom 5 is for passengers in the car 1 to talk to the outside. The intercom 5 is provided with an emergency call button 12 for passengers in the car 1 to operate in an emergency. When the emergency call button 12 is pressed, a predetermined emergency signal is transmitted to the outside.

The camera 6 is provided in the car 1 for the purpose of crime prevention or the like. The camera 6 is, for example,
The field of view and the shooting direction are appropriately set in advance so that the state inside the car 1 (predetermined range) can be photographed and the face can be photographed when the passenger gets into the car. In the present embodiment, it has at least a role as a detection unit for photographing the face of a passenger.

The monitor 7 and the speaker 8 form a role as an alarm that notifies the passengers in the car 1 of various information. During normal operation of the elevator (when the normal service is provided), the monitor 7 and the speaker 8 provide predetermined information useful to passengers such as information on the destination floor, news, and weather forecast. It also has a function as an alarm unit that issues an alarm when a passenger has an abnormality in crime prevention.

The control device 2 is provided with an operation control unit 13, a storage unit 14, a suspicious person determination unit 15, a robot control unit 16, and a robot communication unit 17 that control the operation of the car 1. The control device 2 has a function of controlling the entire elevator including the operation control of the car 1. The control device 2 has a function of issuing a command for crime prevention operation under a predetermined situation, in addition to a normal function (a function of performing normal operation) for appropriately responding to a call registered from the elevator landing or the operation panel 4. ing.

The operation control unit 13 can control the operation of the car 1 and the door drive device (not shown) that opens and closes the car door as the car 1 operates.

The storage unit 14 can store in advance information used for determining a suspicious person, which will be described later. As the storage unit 14, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a magnetic disk device, or the like can be used. The information corresponds to personally identifiable information (hereinafter referred to as identification information) such as legitimate passenger face information, fingerprints, irises, other biological information, ID cards, ID tags, smartphones, and other wireless communication devices. ..

The identification information stored in the storage unit 14 is read out by the control device 2 and used in the suspicious person determination process shown below.

The suspicious person determination unit 15 determines whether the passenger is a suspicious person (a person whose identification information is not registered in advance) or a regular passenger (for example, a face image) based on the passenger's face information (for example, a face image) taken by the camera 6. It is possible to determine whether the person whose identification information is registered in advance: a resident of an apartment, etc.). In FIG. 1, the suspicious person determination unit 15 is illustrated to be provided in the control device 2, but for example, the suspicious person determination unit 15 may be provided in the operation control unit 13. Here, when the camera 6 acquires the face information of the passenger when or after getting into the elevator, it transmits it to the suspicious person determination unit 15 via the operation control unit 13 or directly to the suspicious person determination unit 15. It is configured as.

As a determination method by the suspicious person determination unit 15, for example, the information read from the identification information stored in advance in the storage unit 14 and the face information of the passenger photographed by the camera 6 provided in the car 1 are compared. It is possible to adopt a method of determining whether the user of the elevator is a suspicious person or a regular passenger. In the present embodiment, the camera 6 is used as the detection unit, but information other than the face information may be used as the identification information to detect the identification information.

In the present embodiment, an example in which the camera 6 is provided in the car 1 is shown. For example, a detection unit is provided in the landing, and the information detected by the detection unit and the identification stored in advance are stored. It is also possible for the suspicious person determination unit 15 to determine a suspicious person using the information. Alternatively, after the user enters the building, it is naturally possible to determine a suspicious person in advance using the information detected by the detection unit provided on the route to the landing and the identification information stored in advance. ..

The robot control unit 16 has a function of controlling an autonomous mobile robot 3 that autonomously travels in the building by using an elevator arranged in the building. Further, the robot control unit 16 has a function of instructing and controlling the autonomous mobile robot 3 to perform a predetermined operation when the usage status of the elevator by passengers satisfies a predetermined condition.

The above-mentioned predetermined condition in the present embodiment means a case where a suspicious person and a regular passenger are in the car 1. For example, when a suspicious person and a regular passenger waiting at the landing are both boarding the car 1 at the same time, or when a suspicious person is already in the car registered by the regular passenger waiting at the landing. In addition, a suspicious person and a regular passenger will be on board the car 1. When such a condition is satisfied, the robot control unit 16 is configured to send a command to the autonomous mobile robot 3 to move between a suspicious person riding in the car 1 and a regular passenger. There is.

The following method can be exemplified as a method for determining that the above-mentioned predetermined conditions are satisfied. When the camera 6 acquires the face information of a passenger when or after getting into the elevator, the camera 6 transmits the acquired face information to the suspicious person determination unit 15 via the driving control unit 13 or directly. The suspicious person determination unit 15 compares the information read from the identification information stored in advance in the storage unit 14 with the face information of the passengers taken by the camera 6 provided in the car 1, and the elevator user uses the elevator. Determine if you are a suspicious person or a legitimate passenger. The suspicious person determination unit 15 transmits the determination result to the operation control unit 13. Subsequently, the camera 6 provided in the car 1 detects that both the suspicious person and the regular passenger determined by the suspicious person determination unit 15 are in the car 1, and the detected image information is driven. It is transmitted to the control unit 13. The operation control unit 13 processes the detected image information to determine that both the suspicious person and the regular passenger are in the car 1. In this case, it is determined that the above-mentioned predetermined conditions are satisfied. Of course, the camera 6 may process the image information for determination. Further, the image information in the car 1 showing the passengers detected by the camera 6 may be transmitted to the robot control unit 16 and processed by the robot control unit 16.

The operation control unit 13 starts the security operation of the elevator after determining that both the suspicious person and the regular passenger are in the car 1. When the elevator starts the crime prevention operation, the robot control unit 16 determines that the usage status of the elevator by the passengers satisfies a predetermined condition (security operation), and puts the autonomous mobile robot 3 into the car 1 with respect to the robot communication unit 17. Send a command to control the movement between a suspicious person and a legitimate passenger. Here, not only indicates that the position between the suspicious person and the legitimate passenger is near the middle between the suspicious person and the legitimate passenger, but also, for example, when the suspicious person tries to harm the legitimate passenger. Also includes a position where the autonomous mobile robot 3 becomes an obstacle. In the following, the area between the suspicious person and the regular passenger will be referred to as the crime prevention position. When the robot communication unit 17 receives the control command of the autonomous mobile robot 3, the robot communication unit 17 transmits the control command to the autonomous mobile robot 3. The crime prevention operation includes not only the crime prevention operation of the elevator but also the crime prevention operation of the autonomous mobile robot 3 by itself.

It is also possible to determine whether the operation control unit 13 instead of the robot control unit 16 is a predetermined condition for controlling the autonomous mobile robot 3. In this case, the operation control unit 13 starts the crime prevention operation after determining that both the suspicious person and the regular passenger are in the car 1. When the operation control unit 13 starts the crime prevention operation, the operation control unit 13 transmits a command to the robot control unit 16 to control the autonomous mobile robot 3 to move between the suspicious person in the car 1 and the regular passenger. When the robot control unit 16 receives the control command from the operation control unit 13, the robot control unit 16 transmits the control command to the autonomous mobile robot 3 via the robot communication unit 17.

In order to move the autonomous mobile robot 3 to a crime prevention position, for example, the position information of a suspicious person and a regular passenger in the car 1 is acquired by a camera 6 provided in the car 1, and the position information is used. It is stored in the storage unit 14. The operation control unit 13 or the robot control unit 16 can move the autonomous mobile robot 3 based on the position information stored in the storage unit 14. The autonomous mobile robot 3 may acquire the position information by itself and move to the crime prevention position based on the position information.

After the autonomous mobile robot 3 moves to the crime prevention position, the elevator arrives at the registered destination floor, and when a regular passenger gets out of the car 1, a series of operations are completed and the crime prevention operation is completed. When a suspicious person tries to get off after a regular passenger after arriving at the destination floor where the elevator is registered during crime prevention operation and a regular passenger gets off the car 1, the robot control unit 16 May issue a control command to the autonomous mobile robot 3 to move so as to block the vicinity of the elevator entrance so that a suspicious person cannot get out of the car 1. Whether or not a suspicious person is trying to get out of the car 1 following a regular passenger is determined by, for example, acquiring the operation of the regular passenger and the suspicious person when getting off by the detection unit (camera 6) in the car 1 and from the acquired information. A method of determining by the operation control unit 13 can be adopted. Further, based on the determination result, the operation control unit 13 transmits a command to the robot control unit 16, the robot control unit 16 transmits a control command to the autonomous mobile robot 3 via the robot communication unit 17, and the autonomous mobile robot 3 Can be controlled.

In the present embodiment, it is also possible to determine whether or not the condition is a predetermined condition for controlling the autonomous mobile robot 3 by determining other components of the control device 2.

The robot communication unit 17 has a function that allows the robot control unit 16 to communicate with the autonomous mobile robot 3. For example, the robot control command received by the robot control unit 16 from the operation control unit 13 is transmitted to the autonomous mobile robot 3 via the robot communication unit 17. Further, the robot control unit 16 receives information from the autonomous mobile robot 3 via the robot communication unit 17.

Subsequently, the autonomous mobile robot 3 will be described. The autonomous mobile robot 3 is provided with a control unit 18, a communication unit 19, a mobile unit 20, and an alarm unit 21. The autonomous mobile robot 3 has a function of receiving a control command from the control device 2 to operate, but the autonomous mobile robot 3 may be configured to have a function of issuing a control command and operating by itself.

The control unit 18 has a function of receiving a control command from the control device 2 and controlling the autonomous mobile robot 3 so as to perform crime prevention operation. For example, when the control unit 18 receives a command from the control device 2 to perform crime prevention operation, the control unit 18 gets the autonomous mobile robot 3 into the car 1 in which a suspicious person and a regular passenger are on board and moves to the crime prevention position. It is configured to control. The control unit 18 has a function of controlling the entire autonomous mobile robot 3 including the crime prevention operation control described above.

The communication unit 19 has a function of communicating with the control device 2, that is, a function of communicating between the autonomous mobile robot 3 and the elevator. For example, the communication unit 19 is configured to receive a robot control command from the robot communication unit 17 and transmit it to the control unit 18. Further, in FIG. 1, the communication unit 19 is configured to receive information directly from the robot communication unit 17, that is, to receive information directly from the control device 2. However, the communication path may have a communication function from the control device 2 via various communication devices in the building, and the information from the control device 2 may be received via the relay device. .. The control unit 18 may be configured to control the operation of the autonomous mobile robot 3 based on the received information received by the communication unit 19 from these various communication paths.

The moving unit 20 is configured to be able to move the autonomous mobile robot 3 to a target location. For example, a control command from the robot control unit 16 is received via the robot communication unit 17 and the communication unit 19, the control unit 18 controls the movement unit 20 based on the control command, and the autonomous mobile robot 3 is moved. Can be made to.

The alarm unit 21 has a function of issuing an alarm to a suspicious person when an abnormality in crime prevention occurs in a legitimate passenger and directly intimidating the suspicious person. The alarm may be a sound, or is not particularly limited as long as it can restrain a suspicious person such as emitting light or displaying a hologram on the wall surface.

Although the example in which the autonomous mobile robot 3 operates in crime prevention operation in response to a control command from the control device 2 has been described, the autonomous mobile robot 3 may be configured to be able to perform a crime prevention operation by making a suspicious person determination by itself. ..

The form of the autonomous mobile robot 3 is not particularly limited as long as it can move autonomously, and the robot 3 may travel on the floor in the building by driving wheels or the like, or may fly and move like a drone or the like. It may be a thing. Further, the autonomous mobile robot 3 does not have to be a robot dedicated to crime prevention, and can be substituted by, for example, providing a crime prevention function to a cleaning robot in a building.

Subsequently, the operation of the elevator security system according to the present embodiment will be described with reference to FIGS. 2 to 9. FIG. 2 is a flowchart showing an operation example of the security system according to the present embodiment.

Hereinafter, the operation of the crime prevention system of the present embodiment will be described by taking as an example a case where two elevator users (hereinafter, referred to as user A and user B, respectively) are waiting at the landing.

First, a normal operation (operation 1) in which a suspicious person does not ride will be described.

User A and user B are waiting at the landing, and the autonomous mobile robot 3 is also waiting at the landing (S1).
Subsequently, the elevator operation panel installed at the landing on the floor where the user A is waiting is used to call the landing (S2). In response to this, the control device 2 calls the car and controls the car 1 to move to the floor where the user is waiting.
When the car 1 arrives at the floor where the user is waiting and the landing and the door (door) of the car 1 are opened, the user A and the user B enter the car 1 respectively, and each operates the car 1. Register the destination floor on board 4 (S3).

The camera 6 provided in the car 1 detects the faces of the user A and the user B, and sequentially records the captured images (S4). Further, the recorded captured image may be stored in the storage unit 14 of the control device 2.
Based on the user identification information stored in advance in the storage unit 14 or the like, the suspicious person determination unit 15 determines whether or not the user is a suspicious person from the captured images of the user A and the user B (S5). Although the steps of S4 and S5 have been described here after S3, the timing of performing S3 is not limited to this.

If it is determined that both user A and user B are not suspicious passengers and are regular passengers, the control device 2 does not perform crime prevention operation and operates the car 1 to the registered destination floor. When each user arrives at the destination floor (S6) and the user gets off the car 1 (S7), a series of operations is completed.

Next, the operation (operation 2) when the user A is a regular passenger and the user B is a suspicious person will be described with reference to FIG.

Similar to the example of the operation 1, two elevator users A, a user B, and an autonomous mobile robot 3 are waiting at the landing (S1). The subsequent operation flow from S2 to S5 is the same as in the previous example. In S5, after the suspicious person determination unit 15 determines that the user A is a regular passenger and the user B is a suspicious person, the driving control unit 13 determines whether the regular passenger and the suspicious person are in the car. It is determined whether or not (S8).

After it is determined that a regular passenger and a suspicious person are in the car, the operation control unit 13 of the control device 2 starts the crime prevention operation (S9). After starting the crime prevention operation, the robot control unit 16 issues a control command to the autonomous mobile robot 3 to move to the crime prevention position (S10). The autonomous mobile robot 3 waiting at the landing receives a control command from the robot control unit 16 and gets into the car 1 from the landing while the car 1 and the landing door are open and moves to the crime prevention position.
At this time, the operation control unit 13 of the control device 2 controls the car 1 and the door of the landing to be in the open state until the autonomous mobile robot 3 gets into the car 1 from the landing.
Subsequent operations, S6 to S7, are the same in this example. By the above operation, even when a regular passenger rides with a suspicious person, it can be expected to obtain a deterrent effect on the suspicious person for the safety of the regular passenger. In addition, since the autonomous mobile robot 3 is located in the crime prevention position, it is possible to keep a distance between the regular passenger and the suspicious person, and it exerts a direct deterrent effect on the suspicious person, giving the regular passenger a sense of security. Can be given.

3 to 4 schematically show an example of an operation (operation 2) when the user A is a regular passenger and the user B is a suspicious person. An example in which the operation control unit 13 controls the autonomous mobile robot 3 so as to keep the doors of the car 1 and the landing open until the autonomous mobile robot 3 gets into the car 1 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram showing a case where two users (regular passengers and suspicious persons) waiting at the landing board the car 1 and the autonomous mobile robot 3 is about to board the car 1. Here, the operation control unit 13 of the control device 2 interferes with the opening / closing operation of the doors of the car 1 and the landing, and keeps the doors of the car 1 and the landing open until the autonomous mobile robot 3 gets into the car 1 from the landing. It indicates that it is controlled to be (the door is not closed). This is to prevent a suspicious person from starting the elevator even if he / she tries to start the elevator before the autonomous mobile robot 3 gets into the car 1. Whether or not the autonomous mobile robot 3 has boarded the car 1 can be determined by the operation control unit 13 of the control device 2 based on the image captured by the detection unit (camera 6) provided in the car 1. FIG. 4 is a diagram showing a case where the autonomous mobile robot 3 moves to a crime prevention position in the car 1 by a control command from the robot control unit 16 based on the identification information detected by the detection unit (camera 6).

Subsequently, when a legitimate passenger and a suspicious person are in the car, the operation when the suspicious person tries to harm the legitimate passenger will be described with reference to the flowchart shown in FIG.

In FIG. 5, since the flows from S1 to S8 in the operation flow shown in FIG. 2 are the same, they are not shown and the description thereof will be omitted.
As described above, after it is determined that a regular passenger and a suspicious person are in the car, the operation control unit 13 of the control device 2 starts the crime prevention operation (S9). After starting the crime prevention operation, the robot control unit 16 issues a control command to the autonomous mobile robot 3 to move to the crime prevention position (S10). Based on this control command, when the autonomous mobile robot 3 is located in the crime prevention position, it is determined whether or not a suspicious person is trying to harm a legitimate passenger (S11). The driving control unit 13 can determine whether or not a suspicious person is trying to harm a legitimate passenger, for example, based on the information obtained by photographing the situation in the car 1 by the camera 6.
When it is determined that the suspicious person is trying to harm a legitimate passenger, an alarm is issued from the alarm unit 21 of the autonomous mobile robot 3 (S12). Of course, an alarm may be issued from the speaker 8 provided in the car 1. Even if a situation occurs in which the safety of a legitimate passenger is threatened by such an operation, it can be expected that the safety of a legitimate passenger can be easily ensured by directly intimidating a suspicious person. After that, the operation after the car 1 arrives at the destination floor is the same as that shown in FIG.

Next, in the operation (operation 2) when the user A is a regular passenger and the user B is a suspicious person, another operation example when the regular passenger gets off at the target floor is shown in the flowchart shown in FIG. It will be explained with reference to.

In FIG. 6, since the flows from S1 to S8 in the operation flow shown in FIG. 2 are the same, they are not shown and the description thereof will be omitted. After the car 1 arrives at the destination floor (S6) and the regular passengers get off from the car 1 (S7), it is determined whether or not a suspicious person is about to get off after the regular passengers (S13). Whether or not a suspicious person is trying to get off after a legitimate passenger can be determined by, for example, a camera 6 taking a picture of the situation in the car 1 and the driving control unit 13 based on the pictured information.
When it is determined that the suspicious person is trying to get off after a legitimate passenger, the control device 2 (driving control unit 13 or robot control unit 16) causes the suspicious person to get off the car 1 with respect to the autonomous mobile robot 3. A control command is issued to prevent the above (S14). For example, before the suspicious person gets out of the car 1, the autonomous mobile robot 3 is moved to the vicinity of the elevator entrance so that the suspicious person cannot get out of the car 1 so as to hinder the movement of the suspicious person. For example, FIG. 7 is a diagram schematically showing a situation in which the autonomous mobile robot 3 is preventing a suspicious person from getting off. By making the autonomous mobile robot 3 perform such an operation, it can be expected that the legitimate passengers can get off more safely by suppressing the tailing of the legitimate passengers by the suspicious person.

Subsequently, the autonomous mobile robot 3 starts a crime prevention operation at a place different from the landing where the user is waiting (for example, a place away from the landing on a different floor from the landing or the same floor as the landing). Later, the operation when the autonomous mobile robot 3 is present at a location (a place distant to such an extent that it cannot be quickly moved to the crime prevention position) will be described with reference to the flowchart shown in FIG.

In the operation flow shown in FIG. 8, each step of S2 to S8 and S9 is the same as each step in the operation flow shown in FIG. 2 in this example as well.

It is assumed that user A and user B are waiting at the landing. Since the operation until the two users waiting at the landing are in the car 1 and the crime prevention operation is started is the same in this example, the description thereof will be omitted. After the security operation is started, the robot control unit 16 transmits a control command for the security operation to the autonomous mobile robot 3.

Since the autonomous mobile robot 3 that has received the command from the robot control unit 16 exists at a place different from the landing, it starts autonomous movement toward the landing. Here, it is determined whether or not the autonomous mobile robot 3 is in the crime prevention position (S19), and if the autonomous mobile robot 3 is not in the crime prevention position, the control device 2 keeps the control device 2 until the autonomous mobile robot 3 arrives at the landing. The car 1 on which the user is riding is put on standby for opening (S20). After that, when the autonomous mobile robot 3 arrives at the landing, the autonomous mobile robot 3 gets into the car 1 and moves to the crime prevention position. Subsequently, the car 1 ends the door opening standby state. Subsequent operations are the same as in the example shown in FIG. Due to such an operation, even when the autonomous mobile robot 3 is not waiting at the landing, the elevator does not depart when a regular passenger and a suspicious person are in the car, so that the regular passenger and the suspicious person are in the car 1 together. You will not be trapped inside. In addition, it is possible to create a situation in which regular passengers can evacuate to the outside of the car in case of a crime prevention abnormality. Further, for example, when the door is waiting to be opened (S20), it is conceivable that the user gets off from the car 1. In this case, the step S8 is performed again, and if it is determined that the regular passengers and suspicious persons are not in the car, the security operation is canceled and the control command for the security operation to the autonomous mobile robot 3 is invalidated. It is also possible to do. By doing so, the autonomous mobile robot 3 is in a normal standby state and can be prepared for a control command generated thereafter from the control device 2, so that it is expected that the efficiency of the elevator crime prevention system will be improved.

Subsequently, the operation when the autonomous mobile robot 3 determines a suspicious person and the autonomous mobile robot 3 performs a crime prevention operation by itself will be described. The operation in this case will be described with reference to the flowchart shown in FIG.

In the operation flow shown in FIG. 9, each step of S1 to S2, S6 to S7, and S9 to S10 is the same as each step in the operation flow shown in FIG. 2 in this example as well. Further, in this example as well, the determination of whether or not the passenger is a suspicious person and the determination of whether or not a regular passenger and a suspicious person are in the car can be determined by the same method.

It is assumed that the user A, the user B, and the autonomous mobile robot 3 are waiting at the landing. First, after the user calls the landing (S2), the autonomous mobile robot 3 detects the face of each user (S15). Subsequently, the autonomous mobile robot 3 determines whether or not each user is a suspicious person (S16). Of course, the series of steps S15 and S16 may be performed before S2. Subsequently, the autonomous mobile robot 3 determines whether or not a regular passenger and a suspicious person are in the car 1 (S8). Here, when it is determined that each user is a regular passenger, the subsequent operation is the same as the example shown in FIG. On the other hand, in S8, when it is determined that each user has a legitimate passenger and a suspicious person in the car, the autonomous mobile robot 3 starts the crime prevention operation by itself (S9) and moves to the crime prevention position. (S17). Subsequent operations are the same as in the example shown in FIG.
Further, the autonomous mobile robot 3 may start the crime prevention operation by itself (S9), and the autonomous mobile robot 3 may transmit to the control device 2 that the crime prevention operation has started. In this case, the operation control unit 13 of the control device 2 can control the car 1 and the door of the landing to be in the open state until the autonomous mobile robot 3 gets into the car 1 from the landing.
By enabling the autonomous mobile robot 3 to perform crime prevention operation by itself in this way, it is expected that a similar crime prevention system can be configured, for example, when the autonomous mobile robot 3 is provided in another building.
