The determination unit 31 may determine that the suspicious person S has been detected (YES) by receiving these pieces of information.

[Step S102]
In step S102, the call registration unit 32 stops registering new hall calls and car spares.

[Step S103]
In step S103, after the suspicious person S is detected, the determination unit 31 determines whether or not there is a car call registration on the floor F2 where the suspicious person S is detected, It is judged whether or not there is a registration of a car call passing through. If the determination unit 31 determines that there is registration (YES), the process proceeds to step S104, and if it determines that there is no registration (NO), the process proceeds to step S106.

[Step S104]
In step S104, the call registration unit 32 registers all car calls determined to be registered (YES) in step S103 to the floor F where the suspicious person S is detected (floor F2 in FIG. 1). Change the car call registration to the floor F on the front side. Here, the floor F on the front side is the floor closer to the car 11 than the floor F2, and in the example shown in FIG. 1, it is the floor Fm or the floor Fn.

As a result, although not shown in the flowchart, the drive control unit 34 drives the hoisting machine 14 so that the car 11 lands on the floor F on the near side. Further, the drive control unit 34 drives the car door 11a to open the car door 11a and the landing door 1b when the car 11 reaches the floor F on the near side.

[Step S105]
In step S105, the notification control unit 33 instructs the in-car notification devices 11c of all the cars 11 whose car call registration has been changed in step S104 to the car 11 to make a notification to encourage people to get off the car. At this time, if the in-car notification device 11c is a display device, the notification is performed by display, and if the in-car notification device 11c is a speaker, the notification is performed by voice. In addition, the in-car notification device 11c may notify the current position of the suspicious person S in addition to the notification for prompting the passenger to get off the car 11, thereby calling the attention of the passenger H1 in the car 11.

Thereby, the passenger H1 in the car 11 can be made to get off at the floor before the floor F2 where the suspicious person S is detected without encountering the suspicious person S.

[Step S106]
In step S106, the call registration unit 32 registers a call for dispatching all the cars 11 to the floor F2. This call may be a landing call or a car call. In this case, the registration of the car call changed in step S104 is left as it is, and then the call for allocating the car 11 to the floor F2 is additionally registered. After that, the process proceeds to step S107 in FIG.

Although not shown in the flowchart, the driving control unit 34 controls the hoisting machine so that the car 11 lands on the floor F2 on which the suspicious person S is detected by adding such call registration. drive 14; Further, the drive control unit 34 drives the car door 11a to open the car door 11a and the landing door 1b in a state where the car 11 has landed on the floor F2. However, for the car 11 whose car call registration has been changed in step S104, the car 11 is dispatched according to the changed car call registration. is detected, the car 11 is dispatched to the floor F2.

[Step S107]
In step S107, the determination unit 31 calculates the distance between the suspicious person S and the boarding place Fa based on the signal from the abnormality detection device 20 or the information from the management device 40, and determines the distance between the suspicious person S and the boarding place Fa. is less than or equal to a predetermined distance. Here, the landing Fa is the landing Fa of the floor F (here, the floor F2) where the suspicious person S is detected.

The predetermined distance means that the waiting passenger H2 at the landing Fa of the floor F2 where the suspicious person S is detected gets on the car 11 from the time when the determination unit 31 determines that the suspicious person S is detected in step S101. A distance that the suspicious person S can move between. Therefore, when the distance between the suspicious person S and the platform Fa is less than the predetermined distance, the suspicious person S arrives at the platform Fa before the passenger H2 waiting at the platform Fa gets on the car 11. It becomes possible to

The determination unit 31 calculates the predetermined distance described above from the current positions of all the cars 11 and the floor F2. If it is determined that the distance between the suspicious person S and the platform Fa is equal to or less than the calculated predetermined distance (YES), the process proceeds to step S108. On the other hand, if it is determined that the distance is not equal to or less than the predetermined distance (NO), the process proceeds to step S201 in FIG.

[Step S108]
In step S108, when the suspicious person S is detected in step S101, the determination unit 31 determines whether or not there is a waiting passenger H2 at the boarding point Fa. At this time, for example, it is determined by whether or not the operation for calling the platform has been performed by the platform operation unit 16 of the platform Fa. You may judge from a video signal.

If the judging section 31 judges whether the operation for calling the platform is being performed or that there is a waiting passenger H2 from the image of the security camera 22 (YES), the judging section 31 proceeds to step S109 and judges that there is no waiting passenger H2 (NO). If so, the process proceeds to step S110.

[Step S109]
In step S109, the notification control unit 33 notifies the boarding point notification device 17 of the boarding point Fa to urge evacuation from the boarding point Fa. In this case, for example, notification is made to encourage the use of emergency stairs. At this time, if the hall notification device 17 is a display device, the notification is made by display, and if it is a speaker, the notification is made by voice. In addition, the platform notification device 17 may notify the detection of the suspicious person S together with the notification to encourage the use of the emergency stairs.

Thus, when a suspicious person S is detected at a position near the boarding place Fa, the waiting passengers H2 are urged to evacuate from the boarding place Fa, and the waiting passengers H2 are prevented from encountering the suspicious person S at the boarding place Fa. can be evacuated from After this step S109, the process is ended. A signal from the abnormality detection device 20 is transmitted to the management device 40 . Therefore, the administrator who operates the management device 40 can specify the area where the suspicious person S is detected based on the signal received from the abnormality detection device 20 . Therefore, the administrator can also go to the area where the suspicious person S has been detected.

[Step S110]
On the other hand, in step S110, the notification control unit 33 causes the landing notification device 17 of the landing Fa to notify that the car 11 has arrived. At this time, if the hall notification device 17 is a display device, the notification is made by display, and if it is a speaker, the notification is made by voice. Thereby, the arrival of the car 11 is notified to the suspicious person S arriving at the platform Fa, and the suspicious person S is urged to wait at the platform Fa so that the suspicious person S can get on the car 11.例文帳に追加

[Step S111]
In step S111, the drive control unit 34 keeps the car 11, which has landed on the floor F2, on the floor F2 and waits for the door to open.

[Step S112]
In step S112, the determination unit 31 determines whether or not a suspicious person S has boarded the car 11 based on the signal from the passenger detection device 11d. In this case, the judging section 31 can judge that the passenger is the suspicious person S if it can be confirmed that the passenger has gotten on the car 11 based on the signal from the passenger detection device 11d. boarded (YES), the process proceeds to the next step S113.

[Step S113]
In step S113, the determination unit 31 instructs the drive control unit 34 to dispatch the car 11 to the predetermined floor F1. As a result, the drive control unit 34 closes the car door 11a of the car 11 without depending on the operation from the car internal operation unit 11b, and operates the hoisting machine 14 so that the car 111 lands on the predetermined floor F1. to drive. Further, the determination unit 31 causes the call registration unit 32 to register a call for driving the car 11 as necessary.

Here, the predetermined floor F1 is a predetermined floor among the plurality of floors F, and is not limited to the first floor of the building 1. For example, the doorway of the building 1 is arranged. or a floor where a guard room is located. Thus, the suspicious person S in the car 11 can be guided to the predetermined floor F1 without encountering the passenger H1 and the waiting passenger H2. After this step S113, the process is ended.

[Step S201]
On the other hand, step S201 in FIG. 6 is a step that proceeds after determining in step S107 (see FIG. 5) that the distance between the suspicious person S and the boarding area Fa is greater than the predetermined distance. In this step S201, the judgment unit 31 judges whether or not there is a waiting passenger H2 at the boarding point Fa when the suspicious person S is detected in step S101. At this time, for example, it is determined by whether or not the operation for calling the platform has been performed by the platform operation unit 16 of the platform Fa. You may judge from a video signal.

If the determination unit 31 determines whether the hall call operation has been performed or the image of the security camera 22 indicates that there is a waiting customer H2 (YES), the determination unit 31 proceeds to step S2020 and determines that there is no waiting customer H2 (NO). If so, the process proceeds to step S204.

[Step S202]
In step S202, the determination unit 31 determines whether or not a car call has been input from the intra-car operation unit 11b. If it is determined that the input has been made (YES), the process advances to the next step S203, and the determination is repeated until it is determined that the input has been made (YES).

[Step S203]

As a result, the drive control unit 34 closes the car door 11a of the car 11 and drives the hoist 14 so that the car 11 lands on the predetermined floor F1 in accordance with the input from the intra-car operating unit 11b. . Further, the determination unit 31 causes the call registration unit 32 to register a call for driving the car 11 as necessary.

Thus, when the suspicious person S is detected at a position farther than a predetermined distance from the landing Fa, the waiting passenger H2 at the landing Fa of the floor F2 encounters the suspicious person S before the suspicious person S reaches the landing Fa. The passenger can get on the car 11 and arrive at the target floor. After this step S203, the process is ended. A signal from the abnormality detection device 20 is transmitted to the management device 40 . Therefore, the administrator who operates the management device 40 can specify the area where the suspicious person S is detected based on the signal received from the abnormality detection device 20 . Therefore, the administrator can also go to the area where the suspicious person S has been detected.

[Step S204]
On the other hand, in step S204, the determination unit 31 determines whether or not all the cars 11 arrive at the floor F2 before the suspicious person S who is farther than the predetermined distance from the hall Fa arrives at the hall Fa. carry out the judgment of If it is determined to arrive (YES), the process proceeds to step S205. On the other hand, if it is determined that the vehicle has not arrived (NO), the process proceeds to step S205a.

[Step S205]
In step S205, the drive control unit 34 opens the car doors 11a of all the cars 11 that have arrived at the floor F2 and waits for the doors to open.

[Step S205a]
In step S205a, the drive control unit 34 opens the car door 11a of the car 11 that has arrived at the floor F2 and waits for the door to open.

[Step S206]
In step S206, the determination unit 31 determines whether or not a suspicious person S has boarded the car 11 based on the signal from the passenger detection device 11d. In this case, the judging section 31 can judge that the passenger is the suspicious person S if it can be confirmed that the passenger has gotten on the car 11 based on the signal from the passenger detection device 11d. has boarded (YES), the process proceeds to the next step S207. At this timing, the determination unit 31 may determine that the suspicious person S has boarded the vehicle (YES) when a car call is input from the intra-car operation unit 11b.

[Step S207]
In step S207, the determination unit 31 instructs the drive control unit 34 to dispatch the car 11 to the predetermined floor F1. As a result, the drive control unit 34 closes the car door 11a of the car 11 without depending on the operation from the car internal operation unit 11b, and operates the hoisting machine 14 so that the car 11 lands on the predetermined floor F1. to drive. Further, the determination unit 31 causes the call registration unit 32 to register a call for driving the car 11 as necessary.
