Description

  An embodiment of the present invention relates to an elevator operation control method.

  Since the interior of the elevator car is closed, there is a concern that, for example, when a woman or a child or the like uses the elevator by themselves, a suspicious person who shared the car with malicious intent may suffer a crime. Conventionally, elevators that perform security driving have been proposed for the purpose of preventing such crimes. For example, by performing direct driving to the destination floor designated by the user who got on the car, it is possible to suppress the chance of another person sharing the car on the middle floor and prevent crime in the car beforehand. .

  However, such security operation reduces the efficiency of elevator operation, so it is necessary to accurately determine the necessity of security operation and perform security operation only when there is a high need for security operation. It is desired that crimes in the car can be prevented beforehand without lowering the driving efficiency of the car.

  The problem to be solved by the present invention is to provide an elevator operation control method capable of preventing crime in a car without causing a decrease in the operation efficiency of the elevator due to unnecessary security operation.

The elevator operation control method of the embodiment identifies the attribute and the number of persons at the hall where the hall call has occurred, and the person at the hall is only one person of the first attribute, or of the first attribute. In the case of one person and one person of the second attribute, the operation mode of the elevator is switched from the normal operation mode to the security operation mode. In the security operation mode, after the car has landed on the hall, the car is opened when it is detected that only the person of the first attribute is in the boarding area set near the entrance of the hall. When it is detected that the person having the first attribute has got on the car, the car is closed, and a direct driving operation is performed in which the person goes straight to the destination floor designated by the person having the first attribute. An operation mode of the elevator when it is detected that the person with the first attribute has got off the car on the destination floor, or when it is detected that only the person with the second attribute is in the boarding area. From the security operation mode to the normal operation mode. Even if it is detected that only the person of the first attribute is in the boarding area after the car has landed on the hall, it is set outside the boarding area when viewed from the boarding entrance of the hall. If there is a person of the second attribute in the monitored area, the car keeps the door closed.

  Hereinafter, specific embodiments of an elevator operation control method according to the present invention will be described in detail with reference to the accompanying drawings.

  The elevator to which the present invention is applied has an ordinary operation mode and a security operation mode as operation modes, and is an elevator capable of switching between these operation modes. The normal operation mode is a general operation mode in which a car responds to a registered hall call or car call. On the other hand, the crime prevention driving mode is a driving mode for preventing a crime using the fact that the inside of the car is closed, and is mainly intended to reduce the opportunity for a suspicious person to share a car, such as a woman or child. This is an operation mode in which even if a single user who is likely to suffer crimes such as crime uses an elevator, the user is safely transported to the destination floor.

  In the security operation mode, priority is given to safe transportation of the user over the operation efficiency of the elevator. For this reason, switching to the unnecessary security operation mode causes a decrease in the operating efficiency of the elevator. In the present embodiment, the necessity of driving in the crime prevention driving mode (crime prevention driving) is accurately determined by identifying the attribute and the number of persons at the landing where the landing call has occurred. Only when it is determined, the operation mode of the elevator is switched from the normal mode to the security operation mode to perform the security operation. As a result, it is possible to prevent crime in the car from occurring without causing a decrease in the operation efficiency of the elevator due to unnecessary security operation.

  FIG. 1 is a block diagram illustrating a configuration example of an operation control system 1 that implements an elevator operation control method according to the present embodiment. FIG. 2 is a plan view illustrating a state of a landing 20 of the elevator. For example, as shown in FIG. 1, an elevator operation control system 1 includes a car call device 2, a boarding / alighting detection device 3, a hall call device 4, a video analysis device 5, and an elevator control device 10 that controls the entire operation of the elevator. An audio guide device 6 is connected, and a hall camera 7 is connected to the video analysis device 5.

  The car call device 2 is installed in a car 30 (see FIG. 2) of the elevator, and receives an operation of a car call (designation of a destination floor) by a user who gets on the car 30. A car call signal corresponding to the car call operation received by the car call device 2 is sent to the elevator control device 10. The elevator control device 10 registers a car call (destination floor) according to the car call signal.

  The getting on / off detection device 3 detects a user getting on the car 30 or getting off of the user from the car 30. The boarding / alighting detection device 3 may have any configuration as long as it can detect a user getting on or off the vehicle, and may employ any detection method. For example, when an in-car camera is installed in the car 30, the boarding or getting off of the user may be detected by analyzing a video taken by the in-car camera. Further, when a photoelectric sensor is installed at the entrance 21 of the hall 20 (see FIG. 2), the passenger passing through the entrance 21 is detected by the photoelectric sensor to detect the getting on / off of the user. May be. When the car 30 is provided with a load sensor, the user's entry or exit may be detected based on a change in the load of the car 30 detected by the load sensor. If the angle of view of the hall camera 7 is sufficiently wide, it is possible to detect the user's getting on or off by analyzing the video captured by the hall camera 7. The information on boarding and getting off detected by the boarding / alighting detection device 3 is sent to the elevator control device 10.

  The hall call device 4 is installed in the hall 20 as shown in FIG. 2 and receives a hall call operation by a user of the hall 20. A hall call signal corresponding to the hall call operation accepted by the hall call device 4 is sent to the elevator control device 10. The elevator control device 10 registers a hall call according to the hall call signal.

  The hall camera 7 is installed in the hall 20 as shown in FIG. The image of the hall taken by the hall camera 7 is sent to the video analyzer 5.

  The image analysis device 5 analyzes the image of the hall 20 transmitted from the hall camera 7 of the hall 20 at which the hall call has occurred, in real time, and identifies the attributes and the number of persons in the hall 20. Here, the attributes of the person are, for example, gender, age (age), and the like. As a method of identifying the attribute of a person from a video, a known method such as a method disclosed in Japanese Patent Application Laid-Open No. 2005-165449 can be used, and a detailed description thereof is omitted here.

  In the present embodiment, the attribute of a person who tends to be likely to suffer a crime is referred to as a “first attribute”, and the attribute of a person to be warned is referred to as a “second attribute”. The person with the first attribute is, for example, a woman or a child, and the person with the second attribute is, for example, an adult man. As attributes of the person, other attributes such as clothes and height of the person may be added in addition to the gender and the age (age). In this case, for example, a person wearing sunglasses or a mask, a person wearing a hood from his / her head, a person whose height exceeds a reference value, or the like may be identified as a second attributed person.

  Further, the video analysis device 5 detects the position of the person in the hall 20 where the hall call has occurred by analyzing the image of the hall 20 sent from the hall camera 7 in real time. In the present embodiment, as shown in FIG. 2, the boarding area A1 is set near the entrance 21 of the hall 20. The boarding area A1 is set in a range where the user can immediately get on the car 30, for example, a semicircular area having a radius of about 2 m from the center of the entrance 21. The video analysis device 5 detects, for example, whether the person with the first attribute or the person with the second attribute is in the boarding area A1. The information on the attribute and the number of the person identified by the video analysis device 5 and the information on the position of the person detected by the video analysis device 5 are sent to the elevator control device 10 as needed.

  The voice guidance device 6 is installed in the hall 20 as shown in FIG. 2, and outputs various announcements by voice when the operation mode of the elevator is switched from the normal operation mode to the security operation mode. A specific example of the announcement by the voice guidance device 6 will be described later.

  In FIG. 1, one hall call device 4, one hall camera 7, and one voice guidance device 6 are illustrated, but these are provided for each hall 20 on each floor of the building. The video analysis device 5 may be provided for each landing 20 on each floor, or may be one video analysis device 5 to which the landing cameras 7 on each floor are connected. Further, the hall camera 7 and the voice guidance device 6 may be provided only in the hall 20 with many users, such as the hall 20 on the entrance floor of the building where the elevator is installed.

  As shown in FIG. 1, the elevator control device 10 includes, as functional components related to the present embodiment, an operation mode switching unit 11 that switches the operation mode of the elevator, and a response of the car 30 to a hall call or a car call. And a door open / close control unit 13 for controlling the opening and closing of the door of the car 30. When the operation mode of the elevator is switched from the normal operation mode to the security operation mode by the operation mode switching unit 11, the call response control unit 12 and the door opening / closing control unit 13 perform control different from that in the normal operation mode. The operation mode switching unit 11, the call response control unit 12, and the door opening / closing control unit 13 are realized by a general-purpose processor such as a CPU executing a predetermined program.

  Based on the information sent from the video analysis device 5, the driving mode switching unit 11 determines whether only one person (for example, a woman or a child) of the first attribute is present at the hall 20 where the hall call has occurred, or When it is determined that there is one person with the attribute and one person with the second attribute (for example, an adult male), the operation mode of the elevator is switched from the normal operation mode to the security operation mode. In the present embodiment, the crime prevention driving is performed only in a situation where it is determined that the security driving is necessary according to the attribute of the person in the hall 20 where the hall call has occurred and the identification result of the number of persons.

  When the operation mode of the elevator is switched from the normal operation mode to the security operation mode, first, the voice guidance device 6 installed in the hall 20 where the hall call has occurred outputs a sound indicating that the security operation is performed. This announcement indicates that the car 30 cannot be shared when the security driving is performed, and that the person with the first attribute is in the above-described boarding area A1 (for example, a semicircular area with a radius of about 2 m from the center of the entrance 21). It includes a voice message that informs the user of entering the vehicle, getting out of the boarding area A1 for a person of the second attribute, and performing direct driving when the boarding of only the person of the first attribute is detected. For example, "We will perform security driving. Car sharing is not possible. Women (children) should stand within 2 m from the entrance and men should stand at least 2 m away. If you can confirm that the woman has boarded, go directly I will drive. "

  Thereafter, when the car 30 arrives at the hall 20 in response to the hall call under the control of the call response control unit 12, the door opening / closing control unit 13 controls the door opening of the car 30. Specifically, the door opening / closing control unit 13 opens the basket 30 when it is detected based on the information sent from the video analysis device 5 that only the person with the first attribute is present in the boarding area A1. . If the car 30 has landed on the landing 20 before the announcement of performing the above-described security operation has been completed, the door opening / closing control unit 13 maintains the door closed state of the car 30 until the announcement ends. I do.

  In addition, after the car 30 has landed on the landing 20, the door opening / closing control unit 13 keeps the door of the car 30 closed when there is a person with the first attribute and a person with the second attribute in the boarding area A1. I do. In this case, it is desirable that the voice guidance device 6 again outputs an announcement prompting the person with the second attribute to get out of the boarding area A1.

  In addition, after the car 30 has landed on the landing 20, the door opening / closing control unit 13 maintains the door closed state of the car 30 when there is no person with the first attribute and no person with the second attribute in the boarding area A1. . In this case, it is desirable that the voice guidance device 6 again outputs an announcement prompting the person with the first attribute to enter the boarding area A1.

  In addition, after the car 30 has landed on the landing 20, if it is detected that there is only a person of the second attribute in the riding area A1, the driving mode switching unit 11 changes the driving mode of the elevator from the crime prevention driving mode. Return to normal operation mode. The situation in which the person with the second attribute gets on the basket 30 first is because it is less necessary to perform security driving. In this case, it is desirable that the voice guidance device 6 outputs an announcement indicating that the crime prevention driving is stopped and the normal driving is performed.

  After opening the car 30 in the security operation mode, the door opening / closing control unit 13 closes the car 30 when the getting on / off detecting device 3 detects the entry of the person having the first attribute. That is, in the normal operation mode, the car 30 is closed when the door opening time reaches a certain time or when the door close button is operated in the car 30. In the security operation mode, the person with the first attribute is closed. The basket 30 is closed immediately after the boarding of the car is detected. At this time, the door closing speed of the basket 30 may be faster than that during normal operation. Such door closing control is called high-speed door closing.

  Thereafter, when the car call is registered in accordance with the operation of the car call device 2 by the person having the first attribute in the car 30, the call response control unit 12 controls the direct call to the destination floor designated by the car call. Driving is performed. The direct driving is a driving method in which, even if a hall call is registered on an intermediate floor passing while moving to the destination floor, the car 30 goes straight to the destination floor without responding to the hall call. At this time, it is desirable to keep the destination of the person having the first attribute confidential by not displaying the destination floor on the display installed at the landing 20 on each floor.

  When the car 30 that has moved to the destination floor by the direct driving arrives at the landing 20 on the destination floor, the door opening / closing control unit 13 opens the car 30. Then, when the getting on / off detection device 3 detects the getting off of the person having the first attribute, the operation mode switching unit 11 returns the operation mode of the elevator from the security operation mode to the normal operation mode.

  Hereinafter, an example of a processing procedure of the elevator operation control method according to the present embodiment will be described with reference to a flowchart of FIG. Here, a person with the first attribute will be described as a woman, and a person with the second attribute will be described as an adult man.

  When the hall call device 4 is operated at the hall 20 on the floor of the building where the elevator is installed and the hall call is registered (step S101), the video taken by the hall camera 7 installed on the hall 20 is analyzed. By analyzing with the device 5, the attribute and the number of persons at the hall 20 are identified (step S102). Then, it is determined whether the person at the hall 20 is only one woman or one woman and one adult man (step S103).

  Here, when the person at the landing 20 is neither a woman alone nor a woman and an adult man (step S103: No), the driving mode is not switched and the normal driving is continued. The process ends. On the other hand, when it is determined that the person at the landing 20 is only one woman or one woman and one adult man (step S103: Yes), the driving mode switching unit 11 changes the elevator driving mode to the normal driving mode. Is switched to the security operation mode (step S104). Then, an announcement to perform the above-described crime prevention driving is output as a voice by the voice guidance device 6 (step S105).

  Thereafter, when the basket 30 responding to the landing call arrives at the landing 20, it is determined whether or not only women are in the riding area A1 (step S106). Here, if it is not the situation where there is only a woman in the boarding area A1 (step S106: No), it is subsequently determined whether or not only the adult man is in the boarding area A1 (step S107). . Then, if both the female and the adult male are in the riding area A1, or if both the female and the adult male are not in the riding area A1 (step S107: No), the process returns to the step S105 and the voice guidance device 6 Accordingly, an announcement prompting an adult man to go out of the boarding area A1 or an announcement prompting a woman to enter the boarding area A1 is output as voice, and the subsequent processing is repeated. If only an adult man is in the boarding area A1 (step S107: Yes), the process proceeds to step S113, and the operation mode switching unit 11 changes the operation mode of the elevator from the security operation mode to the normal operation. Mode is restored.

  On the other hand, if only women are in the boarding area A1 (Step S106: Yes), the door 30 is opened by the door opening / closing control unit 13 (Step S108). Then, when the boarding / alighting detection device 3 detects that a woman in the boarding area A1 has boarded the basket 30 (step S109: Yes), the door opening / closing control unit 13 performs high-speed door closing of the basket 30 (step S110). ). Then, when the destination floor is designated by the car call of the woman riding the basket 30, direct driving to the destination floor is performed under the control of the call response control unit 12 (step S111).

  Thereafter, when the car 30 arrives at the landing 20 on the destination floor by direct driving, the door opening / closing control unit 13 opens the door of the car 30. Then, when the boarding / alighting detection device 3 detects that the woman in the car 30 gets off from the car 30 (step S112: Yes), the driving mode switching unit 11 changes the operation mode of the elevator from the security driving mode to the normal driving mode. Is returned to (step S113).

  As described above in detail with reference to specific examples, the elevator operation control method according to the present embodiment identifies the attribute and the number of persons in the hall 20 where the hall call has occurred, and is in the hall 20. When the person is only one person with the first attribute (for example, a woman or a child) or one person with the first attribute and one person with the second attribute (for example, an adult man), the operation mode of the elevator is set to the normal operation. Switch from security mode to security operation mode. Then, after the basket 30 has landed on the landing 20, when it is detected that only the person of the first attribute exists in the riding area A1 set near the landing 20, the cage 30 is opened and the first door is opened. When the riding of the person with the attribute is detected, the car 30 is closed at a high speed and the direct driving is performed in which the car 30 goes straight to the destination floor designated by the person with the first attribute. Then, when the car 30 arrives at the destination floor and the getting off of the person of the first attribute is detected, the elevator operation mode is returned from the security operation mode to the normal operation mode. Further, the elevator operation mode is switched from the normal operation mode to the crime prevention operation mode, and after the car 30 has landed on the hall 20 where the hall call has occurred, the second attribute of the second attribute is set in the boarding area A1 set near the hall 20. When it is detected that only a person is present, the security operation is stopped, and the operation mode of the elevator is returned from the security operation mode to the normal operation mode. As described above, the elevator operation control method according to the present embodiment sets the elevator operation mode to the normal mode only when it is determined that there is a high necessity for security operation according to the attributes and the number of persons in the hall 20. Is switched to the crime prevention driving mode to perform the crime prevention driving, so that crime in the car can be prevented beforehand without lowering the operation efficiency of the elevator due to unnecessary crime prevention driving.

  Further, according to the elevator operation control method according to the present embodiment, when the operation mode of the elevator is switched from the normal operation mode to the crime prevention operation mode, only the person in the boarding area A1 has the first attribute. In such a manner, the announcement to be guided is output as a voice, so that the situation where only the person of the first attribute is present in the boarding area A1 can be promoted, and the security driving can be appropriately performed.

<First Modification>
In the above-described embodiment, when the operation mode of the elevator is switched from the normal operation mode to the crime prevention operation mode, after the basket 30 has landed on the hall 20 where the hall call has occurred, the person having the first attribute is set in the boarding area A1. The basket 30 is opened when it is detected that only a person (eg, a woman or a child) is present, and the basket 30 is closed at a high speed when the riding of a person having the first attribute is detected. However, when the distance between the person with the first attribute in the riding area A1 and the person with the second attribute (for example, an adult man) outside the riding area A1 is short, the person with the first attribute gets on the basket 30 and Even if the door is closed, if the person with the second attribute goes to the entrance 21 in a hurry, there is a concern that the person may be shared with the car 30. Therefore, even when it is detected that only the person of the first attribute is present in the boarding area A1, it is detected that the person of the second attribute is present in the monitoring area A2 set outside the boarding area A1. In such a case, the basket 30 may be kept closed.

  In the present modified example, as shown in FIG. 4, an area within a predetermined range outside the boarding area A1 when viewed from the entrance 21 of the hall 20 is set as the monitoring area A2. For example, when the boarding area A1 is a semicircular area having a radius of about 1 m from the center of the entrance 21, the monitoring area A2 is set to, for example, an area up to about 2 m outside the boarding area A1.

  When the operation mode of the elevator is switched from the normal operation mode to the crime prevention operation mode, the door opening / closing control unit 13 of the present modified example transmits the image data from the video analysis device 5 after the basket 30 has landed on the hall 20 where the hall call has occurred. Based on the transmitted information, it is determined whether or not only the person with the first attribute exists in the boarding area A1, and if there is only the person with the first attribute in the boarding area A1, furthermore, the person with the first attribute is further included in the monitoring area A2. It is determined whether there is a person with two attributes. Then, when it is detected that only the person of the first attribute is present in the boarding area A1 and it is detected that the person of the second attribute is not present in the monitoring area A2, the basket 30 is opened, and In other cases, the cage 30 is kept closed.

  As described above, in the present modification, even if it is detected that only the person of the first attribute is present in the boarding area A1, the second attribute is set in the monitoring area A2 set outside the boarding area A1. When it is detected that there is a person, the car 30 can be kept closed to thereby more effectively suppress the sharing by persons of the second attribute and improve safety.

<Second modification>
At the landing 20 on the entrance floor of the building where the elevator is installed, it is necessary to consider the use of the elevator by persons entering the building. That is, when performing a crime-prevention operation by the method described in the above-described embodiment, if a person who has no problem even if sharing the car 30 enters the building, the vehicle returns to the normal operation and the person who enters the building immediately It would be desirable to have access to an elevator. Therefore, when the hall call at which the hall call has occurred is the hall 20 on the entrance floor of the building, and when the operation mode of the elevator is switched from the normal operation mode to the security operation mode, the attributes and the number of persons entering the building are further increased. When it is detected that one or more persons of the first attribute or a plurality of persons enter the building, if the person of the first attribute in the boarding area A1 is not in the car, the elevator The operation mode may be returned from the security operation mode to the normal operation mode.

  FIG. 5 is a block diagram illustrating a configuration example of an elevator operation control system that realizes this modification. The difference from the above-described operation control system shown in FIG. 1 is that not only the hall camera 7 but also the entrance monitoring camera 8 installed at the entrance of the building is connected to the video analysis device 5.

  The entrance monitoring camera 8 captures a video of the entrance of the building and sends it to the video analysis device 5. The video analysis device 5 analyzes the entrance video captured by the entrance monitoring camera 8 in real time, in addition to the video of the landing 20 captured by the landing camera 7, and identifies the attributes and the number of persons entering the building. .

  The operation mode switching unit 11 according to the present modification generates a hall call at the hall 20 on the entrance floor, and the hall 20 has only one person (for example, a woman or a child) of the first attribute or the first person. When there is one person with the attribute and one person with the second attribute (for example, an adult male), the operation mode of the elevator is switched from the normal operation mode to the security operation mode. Thereafter, crime prevention driving is performed by the method described in the above-described embodiment. However, if it is detected that a person (one person) or a plurality of persons having the first attribute has entered the building, the first attribute in the boarding area A1 is detected. If a person with one attribute is not in the car, the driving mode switching unit 11 returns the driving mode of the elevator from the crime prevention driving mode to the normal driving mode so that the person entering the building can board the car 30. I do. In this case, it is desirable that the voice guidance device 6 outputs an announcement indicating that the crime prevention driving is stopped and the normal driving is performed. In addition, when the person who entered the building is one person of the second attribute, the security driving is continued.

  As described above, in this modification, when a hall call occurs at the hall 20 on the entrance floor and the operation mode of the elevator is switched from the normal operation mode to the security operation mode, the attributes and the number of persons entering the building are changed. By further identifying and returning to normal operation only when it is assumed that there will be no security problems even if people entering the building are allowed to share, further reduction in driving efficiency due to security driving will be further reduced. Can be suppressed. In addition, when the person who entered the building is one person of the second attribute, the security operation is maintained, so that the safety does not decrease.

<Third Modification>
The method of determining whether a person who enters the building where the elevator is installed is a person who can safely ride on the car 30 is not limited to the above-described method of determining the attribute and the number of persons who enter the building. For example, if the building is a condominium or other apartment complex and an auto-lock system is installed to restrict entrance to the entrance, the unlock information of this auto-lock system (auto-lock is released by key operation or released by remote operation) It is also possible to determine whether or not the person entering the building is a person who has no problem even if he / she rides on the basket 30 by using the information indicating whether or not the person enters the building. That is, when the auto lock is released by the key operation, the person entering the building is a resident of the building, and it can be determined that there is no problem even if the car 30 is shared. On the other hand, when the auto lock is released by remote operation (operation of a button provided on the intercom in the living room), it can be determined that the person entering the building is an external person and that sharing of the car 30 should be avoided. .

  Therefore, in this modification, when the hall call at which the hall call occurred is the hall 20 on the entrance floor of the building, and the operation mode of the elevator is switched from the normal operation mode to the security operation mode, the unlocking of the auto lock system is performed. Get information. If the unlock information indicates that the entrance auto-lock has been released by a key operation, and if the person with the first attribute in the boarding area A1 is not in the car, the operation of the elevator is performed. The mode is returned from the security operation mode to the normal operation mode.

  FIG. 6 is a block diagram illustrating a configuration example of an elevator operation control system that realizes this modification. The difference from the above-described operation control system shown in FIG. 1 is that an automatic lock system 9 is connected to the elevator control device 10. The automatic lock system 9 releases the automatic lock of the entrance in response to a key operation by a resident of the building or an operation of a button provided on an intercom in the living room of the building. The elevator control device 10 of the present modified example can acquire from the auto lock system 9 unlock information indicating whether the auto lock of the entrance has been released by a key operation or a remote operation.

  The operation mode switching unit 11 according to the present modification generates a hall call at the hall 20 on the entrance floor, and the hall 20 has only one person (for example, a woman or a child) of the first attribute or the first person. When there is one person with the attribute and one person with the second attribute (for example, an adult male), the operation mode of the elevator is switched from the normal operation mode to the security operation mode. After that, crime prevention driving is performed by the method described in the above-described embodiment. However, when a resident who has released the automatic lock of the entrance by key operation enters the building, the person with the first attribute in the boarding area A1 is placed in the basket. Before boarding, the operation mode switching unit 11 returns the operation mode of the elevator from the crime prevention operation mode to the normal operation mode so that the resident who has entered the building can get on the car 30. In this case, it is desirable that the voice guidance device 6 outputs an announcement indicating that the crime prevention driving is stopped and the normal driving is performed. In addition, when the automatic lock of the entrance is released by remote control, the security operation is continued.

  As described above, in this modification, when a hall call occurs at the hall 20 on the entrance floor and the elevator operation mode is switched from the normal operation mode to the security operation mode, the unlock information of the auto lock system 9 is acquired. However, by returning to the normal operation only when the resident who has released the automatic lock of the entrance by key operation enters the building, it is possible to further suppress a decrease in the driving efficiency due to the security operation. In addition, when the automatic lock of the entrance is released by a remote operation and an outside person enters the building, the security operation is maintained, so that the safety does not decrease.
