For example, an elevator includes a hoistway 1, a car 5 in which elevator users ride, a counterweight 4, a motor 3 installed at an arbitrary position, and a main body that is wound around the motor 3 and suspends the car 5 and the counterweight 4. Monitoring via a rope 2, an elevator control device 7 for controlling the operation of the elevator, an elevator monitoring device 8 for monitoring the elevator, a control panel 6 housing the elevator control device 7 and the elevator monitoring device 8, and a communication line 10 A communication device 9 that communicates with the center device 11 is provided.

The elevator monitoring device 8 includes an elevator monitoring unit 20 that monitors the elevator, an operation data reception unit 21 that receives operation data of the elevator, and an operation method switching unit 22 that switches the operation method of the elevator.

According to the example shown in FIG. 1, there are floors one to four. The hoistway 1 is for four floors. A landing door 12 is installed at each landing on the first to fourth floors. By rotating the motor 3 in forward and reverse directions, the car 5 is driven up and down. The car 5 stops at a landing level 14 indicating the stop position of each floor according to the destination floor, and the car door 15 and the landing door 12 of the landing floor open. The elevator car 5 is driven up and down by registering the destination floor with a car call button 16 in the car 5 or by calling the car 5 with a hall call button 13 provided at the hall of each floor. An image monitoring device 17 (for example, a camera inside the car 5 and a device for analyzing images taken by the camera) is installed in the car 5 so as to detect violent movements of passengers. The image monitoring device 17 communicates with the elevator monitoring device 8 via a communication line (not shown). A “passenger” is an elevator user in the car 5 .

In this embodiment, there are "normal operation" and "non-stop operation" as elevator operation methods.

"Normal operation" is an operation mode in which the car 5 stops at both the destination floor registered by the car call and the destination floor registered by the hall call.

"Direct operation" is an operation method for one purpose of preventing car-calling, and is an operation method in which the car goes directly to the destination floor without responding to the hall call during the car call. Specifically, direct operation is an operation method that satisfies the following (a) and (b).
(a) When there are passengers (in other words, when there is a destination floor registered by the car call), the car 5 does not stop at the destination floor registered by the car call, but the destination floor registered by the car call The car 5 stops only at .
(b) When there are no passengers (in other words, when there is no destination floor registered by the car call), the car 5 stops at the destination floor registered by the hall call.

"Optional contract for detection of disturbance" is one of the optional contracts for the maintenance contract of the elevator, and when a disturbance is detected in the building 18, It is a contract for the use of a service that automatically switches the driving method to direct driving without going through.

An example of the outline of this embodiment is as follows. When the image monitoring device 17A of the building A detects the violent action of the passenger from the photographed image of the camera installed in the car of the elevator of the building 18A, the detection of the violent action is notified. The elevator monitoring device 8A receives the notification, generates an alert, and transmits the alert to the monitoring center device 11. FIG. The monitoring center device 11 includes an operation data collection unit 26 , an alarm reception unit 25 , an average waiting time calculation unit 33 , an implementation period calculation unit 27 , a status notification unit 29 and a direct operation setting unit 28 . The driving data collection unit 26 collects from the monitoring device 8 of each building 18 registration number information representing the number of registrations of hall calls during operation of the car (typically during normal operation), and creation of hall calls ( (Registration) and waiting time information representing the waiting time until the car arrives at the destination floor of the hall call is collected as operation data. The report receiving unit 25 receives the report of the rampage detection from the elevator monitoring device 8A. For example, the alarm receiving unit 25 identifies building A from the received alarm, identifies building B as a neighboring building of building A, and identifies building B as a neighboring building of building A. is the building B to the average waiting time calculation unit 33 and the status notification unit 29 . The average waiting time calculation unit 33 calculates the average waiting time from creation of a platform call to arrival of a car for each operation method (normal operation and direct operation) from the operation data collected for building B. The implementation period calculation unit 27 compares the average waiting time for the non-stop operation and the determination threshold to calculate the implementation period for the non-stop operation. When the direct operation setting unit 28 receives the detection of the rampage of the building A, in addition to (or instead of) the owner of the building A, the owner of the neighboring building B of the building A is notified of the intrusion of a suspicious person; and providing a proposal to switch the elevator operation mode to direct operation during the period calculated by the implementation period calculation unit 27 . When the non-stop operation setting unit 28 receives permission to switch to non-stop operation from the owner of the building B, it transmits a command to switch to the non-stop operation to the elevator monitoring device 8B of the building B.

According to this outline, the monitoring center device 11 notifies the owner of the building A and the owner of the nearby building B of the detection of the disturbance in the building A, thereby notifying the owner of the building A and the neighboring building B. The owner can also know the appearance of a suspicious person. In addition, by switching the operation method of the elevator in the building B to direct operation for a certain period of time, users can use the elevator in the building B without anxiety even under a situation where a suspicious person appears in the neighborhood. In addition, by notifying the owner of building B of the average waiting time from the creation of the platform call for normal operation and non-stop operation, the owner of building B can confirm the impact on operation efficiency due to the setting of non-stop operation. can.

The elevator monitoring device 8 includes an elevator monitoring section 20 , an operation data receiving section 21 and an operation method switching section 22 . When the elevator monitoring unit 20 receives the notification of the detection of the rampage, the elevator monitoring unit 20 generates a report of the rampage detection and transmits the report of the rampage detection to the report receiving unit 25 of the monitoring center device 11 via the communication device 9 . do. The operation data receiving unit 21 stores the received operation data in, for example, the storage device of the elevator monitoring device 8 each time it receives the operation data. The operation method switching unit 22 sets the elevator control unit 23 of the elevator control device 7 to switch the operation method to the direct operation when receiving the direct operation switching command.

The elevator control device 7 includes an elevator control section 23 and an operation data transmission section 24 . The elevator control unit 23 controls operation of the elevator. For example, the elevator control unit 23 switches the operation mode to direct operation in response to the setting for switching to direct operation. The operation data transmission unit 24 transmits, as the operation data of the elevator, the information on the number of registrations of hall calls during running and the waiting time information from the creation of the hall call to the arrival of the car 5 into the operation data in the elevator monitoring device 8. It periodically transmits to the receiving unit 21 . In addition to the information on the number of registrations of hall calls and the waiting time information for each hall call, other types of information may be employed as the operation data.

The monitoring center device 11 is a device for remotely monitoring elevators in each of building A and building B. FIG. The monitoring center device 11 may be a physical device comprising a communication interface device 301, a storage device 302, and a processor 303 connected thereto, or may be realized on the physical device (for example, cloud infrastructure). It may be a logical device. For example, when one or more programs in the storage device 302 are executed by the processor 303, the alarm reception unit 25, the operation data collection unit 26, the implementation period calculation unit 27, the direct operation setting unit 28, the situation The notification unit 29 and the average waiting time calculation unit 33 are implemented in the monitoring center device 11 .

Via the communication interface device 301, it is possible to communicate with the communication device 9 of each building 18 and the smartphone (an example of an information processing terminal of a right holder) of the owner of each building 18 (an example of a predetermined right holder regarding the building 18). can.

Storage device 302 stores management information 315 relating to remote monitoring of elevators. The management information 315 includes, for example, a building ID, a building name, a group of driving data (collection time and collected driving data), and building position information (for example, latitude and longitude data of the building 18, address of the building 18) for each building 18. , and owner information of building 18 (e.g., owner's name, contact information (e.g., e-mail address, or ID of application as status display unit 31), subscription status to option contract for violence detection (e.g., subscribed , on trial, not subscribed and not on trial, etc.) ) .

The driving data collecting unit 26 periodically collects the driving data stored by the driving data receiving unit 21 via the communication device 9 and stores the collected driving data in the storage device 302, for example. The collected driving data is used for calculation by the average waiting time calculator 33 .

When the notification receiving unit 25 receives the notification of the detection of the passenger's disorder, the status notification unit 29 sends information to the neighbors of the building A in addition to the smartphone (not shown) owned by the owner of the building A where the disorder was detected. The smart phone 32 owned by the owner of the building B is notified of the appearance of a suspicious person and a proposal to switch the operation mode of the elevator in the building B to direct operation. In addition, the status notification unit 29 provides information on the number of violent disturbances detected within a certain period of time for elevators maintained by the elevator maintenance company in building B, and information on subscribing to optional contract for violent detection. The owner of building B can know that a suspicious person has appeared in the neighborhood of building B and can switch the driving mode to direct driving. Also, the owner of building B can decide whether to switch to non-stop operation by comparing the average waiting time during normal operation and the predicted average waiting time during non-stop operation. In addition, the owner of Building B should consider subscribing to an optional contract for detecting disturbances by referring to the number of disturbances detected within a certain period of time or other information regarding elevators maintained by the elevator maintenance company of Building B. can be done. Also, when the owner of Building B decides to subscribe to the riot detection option, he can subscribe by following the instructions provided.

The average waiting time calculation unit 33 calculates the average waiting time in normal operation (average waiting time from creation of a hall call until arrival of the car 5) based on the waiting time information for each hall call in the collected operation data. calculate. In addition to the waiting time information for each hall call, the average waiting time calculation unit 33 determines whether the driving method is switched to direct operation based on the information on the number of times hall calls are registered during normal operation in the collected driving data. , the predicted average waiting time in a certain period of time (average waiting time from creation of a hall call to arrival of the car 5) is calculated. In addition, the average waiting time calculation unit 33 is based on the waiting time information for each hall call in the operation data collected after the operation mode is switched to the direct operation (that is, the operation data during the direct operation). Calculate the actual average waiting time, which is the actual value of the average waiting time of .

The implementation period calculation unit 27 compares the predicted average waiting time calculated by the average waiting time calculation unit 33 with a predetermined determination threshold, and calculates the implementation period of direct operation. For example, "a certain period of time after the operation mode is switched to direct operation" is set to "time T" (for example, 2 hours). If the predicted average waiting time is equal to or greater than the determination threshold, the implementation period calculation unit 27 determines the implementation period of direct operation based on the time T to be a relatively short period (for example, about 30 minutes to 1 hour). ). On the other hand, if the predicted average waiting time is less than the determination threshold, the implementation period calculation unit 27 determines the implementation period of direct operation for a relatively long period (for example, from 1 hour to 2 hours).

When the nonstop operation setting unit 28 receives a reply indicating consent to switch the operation method to the nonstop operation, the nonstop operation setting unit 28 transmits a command to switch the operation method to the nonstop operation to the operation method switching unit 22 of the elevator monitoring device 8. .

A smartphone 32 includes a communication device 30 (an example of a communication interface device) and a status display section 31 . The status display unit 31 may be realized by executing a program (for example, an application program) by a processor in the smartphone 32 . The status display unit 31 receives information from the status notification unit 29 of the monitoring center device 11 via the communication device 30, and displays a status management screen based on the received information. The status display unit 31 receives an answer as to whether or not to approve the switching of the driving method, and notifies the direct operation setting unit 28 of the answer.

FIG. 3 is a diagram showing an example of a situation management screen displayed by the situation display section 31. As shown in FIG.

The status management screen 350 is an example of a user interface, such as a GUI (Graphical User Interface). According to the example shown in FIG. 3 , the situation management screen 350 displays waiting time information 351 , operation switching information 352 , rampage detection situation information 353 , and guidance information 354 . At least part of the information 351 to 354 need not be displayed on one screen or at the same time, and may be displayed on multiple screens or at different timings.

The latency information 351 includes a latency graph 361, for example. The waiting time graph 361 represents the average waiting time for normal operation and the expected average waiting time for non-stop operation. When the actual average waiting time is calculated based on the operation data after the operation mode is switched to direct operation, the information indicating the actual average waiting time is transmitted from the status notification unit 29 to the status display unit 31, and the actual average waiting time is calculated. The time is displayed in latency graph 361 .

The driving switching information 352 is information representing a notification of an appearance of a suspicious person, a proposal to switch to direct driving, and a period during which direct driving is to be implemented. Operation switching information 352 includes a “set” button 362 and a “do not set” button 363 . Pressing the "Set" button 362 is an example of acceptance of switching to direct operation. Pressing the "do not set" button 363 is an example of refusing to switch to direct operation.

The disturbance detection status information 353 includes the total number of disturbance detections (e.g., "15 cases") obtained during a predetermined period (e.g., this month) for elevators maintained by the elevator maintenance company in building B, and the number of detections for the vicinity of building B for a predetermined period. This is information representing the number of violent disturbances detected (for example, "4 cases") and its breakdown (for example, the number of violent disturbances detected for each of the area to which building B belongs and its surrounding areas). The aggression detection status information 353 may include information representing the location where the aggression detection occurred in the surrounding area of the building B. FIG. When the position is displayed on the map, a method of displaying using a figure showing the range so that the building cannot be specified in consideration of privacy may be adopted.

Guidance information 354 is information representing guidance for subscribing to an optional contract for detection of violence. When the "Subscribe" button 365 is pressed, for example, a screen for applying for subscription to an optional contract for violence detection is displayed.

Next, an example of processing performed in this embodiment will be described with reference to FIGS. 4 and 5. FIG.

First, referring to FIG. 4, the process of switching to direct operation will be described.

In S101, the driving data collection unit 26 periodically collects the driving data (information on the number of hall calls registered during normal operation and waiting time information for each hall call) stored by the driving data receiving unit 21B.

In S102, if the violent detection unit 19A detects the violent movement of the passengers from the photographed image inside the car 5 of the elevator installed in the building A (S102: YES), it notifies the detection of the violent behavior to the elevator monitoring unit 20A, In S103, the elevator monitoring unit 20A generates a violent detection report, and transmits the violent detection report to the report receiving unit 25 via the communication device 9A. If the violent motion detector 19A does not detect the violent motion of the passenger (S102: NO), the process returns to before S101 (that is, waiting for collection of driving data).

In S104, the average waiting time calculation unit 33 calculates the average waiting time in normal operation based on the collected driving data (for example, the driving data within the past predetermined time after receiving the alarm). Calculate the predicted average waiting time P after the mode is switched to direct operation.

In S105, the implementation period calculation unit 27 determines whether or not the predicted average waiting time P is equal to or greater than the determination threshold Th. If the result of the determination is true (S105: YES), the implementation period calculation unit 27 sets the implementation period of direct operation to a relatively short period (for example, 30 minutes to 1 hour). On the other hand, if the determination result is false (S105: NO), the implementation period calculation unit 27 sets the implementation period of direct operation to a relatively long period (for example, 1 hour to 2 hours). For example, if the predicted average waiting time P is 60 seconds and the determination threshold Th is 70 seconds, even if the driving method is switched to direct operation, the effect on the decrease in driving efficiency is small, so the implementation time of direct operation is a relatively long period.

In S108, the situation notification unit 29 notifies the situation display unit 31 of the smartphone 32 owned by the owner of the building B located in the vicinity of the building A in which the rampage was detected that the suspicious person appears and implements direct driving. A notification of the period, a proposal to switch to direct operation, information representing the average waiting time for each operation method, and a notification of the number of rampage detections obtained this month in elevators maintained by the elevator maintenance company in Building B. , to send information including invitations to subscribe to optional contracts for rampage detection.

In S109, based on the information from the status notification unit 29, the status display unit 31 displays the status management screen 350 illustrated in FIG. The display of the smart phone 32 displays a driving implementation period, an average waiting time for each driving method, and a guide to subscribing to an option contract for the rampage detection. The owner of the building B can voluntarily subscribe to the optional contract for the violence detection by operating the smart phone 32 .

In S110, when the nonstop operation setting unit 28 receives a response from the status display unit 31 that the owner of building B has consented to switching to nonstop operation (S110: YES), in S111, the nonstop operation setting unit 28: A command for switching to direct operation is transmitted to the operation method switching unit 22B via the communication device 9B. In response to the command, the operation method switching unit 22B instructs the elevator control unit 23B to switch the operation method of the elevator from normal operation to direct operation. The system is switched from normal operation to direct operation. If the non-stop operation setting unit 28 receives an answer indicating that the building owner of building B has refused to switch to non-stop operation (S110: NO), the process returns to before S101.

Next, referring to FIG. 5, the process of returning to normal operation will be described.

In S201, when the implementation period of the non-stop operation has passed since the operation method was switched to the non-stop operation (S201: YES), in S202, the non-stop operation setting unit 28 changes the operation method switching unit 22 through the communication device 9B. to send a command to switch to normal operation. In response to the command, the operation method switching unit 22 instructs the elevator control unit 23B to switch the operation method of the elevator from direct operation to normal operation. The system is switched from direct operation to normal operation. It should be noted that another method, for example, a method of returning without a command from the monitoring center device 11, may be adopted for returning to normal operation. Specifically, for example, the command to switch to nonstop operation includes information indicating the implementation period of nonstop operation, and the operation method switching unit 22B performs nonstop operation after the operation method is switched to nonstop operation. It is also possible to detect that the period has elapsed and automatically instruct the elevator control unit 23B to switch the operation mode from direct operation to normal operation.

In S203, the driving data collecting unit 26 collects the driving data stored by the driving data receiving unit 21B (for example, waiting time information for each hall call obtained from the start to the end of direct driving).

In S204, the average waiting time calculation unit 33 calculates the actual average waiting time for direct operation based on the driving data collected in S203. The status notification unit 29 transmits information including information representing the calculated actual average waiting time to the status display unit 31 .

In S<b>205 , the status display unit 31 displays the average waiting time for normal driving and the actual average waiting time for direct driving on the display of the smartphone 32 based on the information from the status notification unit 29 . The owner of building B can compare the operating efficiency in direct operation with the operating efficiency in normal operation.

As described above, according to the present embodiment, the owner of building B in the vicinity of building A in which a disturbance has been detected recognizes the presence of a suspicious person and consents to switching to direct driving. It is possible to enable the users of the building B to use the elevator without anxiety even in a situation where it appears frequently. In addition, the owner of building B can determine whether or not to approve switching to non-stop operation by confirming the effect of setting to non-stop operation on operating efficiency. In addition, the owner of building B can consider subscribing to an optional contract for detecting disturbances, referring to the number of cases of disturbance detections for the elevators maintained by the maintenance company of building B's elevators.

The above-described embodiments can be summarized, for example, as follows.

A monitoring center device 11 (an example of an elevator remote monitoring system) includes a notification receiving section 25 and a direct operation setting section 28 . The alarm receiving unit 25 issues an alarm indicating that a violent motion of a passenger is detected from an image taken by a camera installed in the car of the elevator in building A (an example of the first elevator in the first building). Information is received from a management system A (for example, a system including an elevator control device 7A and an elevator monitoring device 8A) that manages an elevator installed in a building A. "Managing" an elevator may include at least one of monitoring and controlling the elevator. When the alarm is received, the direct operation setting unit 28 instructs the management system B (for example, the system including the elevator control device 7B and the elevator monitoring device 8B) that manages the elevators owned by the building B in the neighborhood of the building A. On the other hand, a switching command, which is a command for switching to direct operation, is transmitted. Thereby, the security of the building B can be improved.

Note that the "neighborhood of building A" is a location defined as being in the neighborhood of building A's location. The "position defined to be in the vicinity of the position of building A" is, for example, any position on a circle with a radius of Xm centered on the position of building A (for example, latitude/longitude or address), or A location or the like in the area to which the location of building A belongs can be adopted. Which building is located at a position defined to be near the position of building A depends on the fact that the alarm was issued from building A and at least part of the management information 315 described above (for example, for each building). information representing the position of the ). The identification of building B in the vicinity of building A may be performed by at least one of the alarm receiving unit 25, average waiting time calculating unit 33, and status notification unit 29. 2 may be performed by an independent function not illustrated (e.g., a corresponding building identifier (not shown) that identifies building B at a location defined as being in the neighborhood of building A's location). Also, the "region" may be, for example, a range corresponding to a predetermined upper part of the address.

Also, the command sent to the management system B in response to the alarm may be a stop of the elevator (for example, a stop of the car to the nearest floor) instead of a command to switch to direct operation. By adopting switching to , it can be expected that both improvement of crime prevention and reduction of deterioration in driving efficiency can be achieved.

The monitoring center device 11 may further include a status notification section 29 . When the notification of the detection of rampage in building A is received, the status notification unit 29 notifies the owner of building B of the appearance of a suspicious person and proposes switching the operation mode of the elevator in building B to direct operation. and may be output. The non-stop operation setting unit 28 may transmit a command to switch to non-stop operation to the management system B in response to receiving approval for switching to non-stop operation from the owner of building B. As a result, switching to non-stop operation can be performed after approval of the building B owner.

Note that the owner of building B is an example of a predetermined right holder for building B. FIG. Instead of or in addition to the owner, for example, a security company may be employed as such a right holder.

The monitoring center device 11 may further include a driving data collection unit 26 , an average waiting time calculation unit 33 and an implementation period calculation unit 27 . The operating data collection unit 26 may collect the operating data of the building B elevator. Based on the collected operation data, the average waiting time calculation unit 33 may calculate the predicted average waiting time for a certain period of time after the operation mode of the elevator in building B is switched to direct operation. The implementation period calculation unit 27 may calculate a period corresponding to the length of the predicted average waiting time as the implementation period for the direct operation of the elevator in the building B. FIG. The implementation period of the non-stop operation of the elevator in building B may be the implementation period calculated above. As a result, the period during which direct operation is implemented is set to a period corresponding to the predicted average waiting time, so it can be expected to optimize the period during which driving efficiency decreases while improving crime prevention. For example, if the predicted average waiting time is greater than or equal to the threshold, it can be considered that the number of users is relatively large, that is, the security is relatively high. The period may be the period during which direct operation is performed. On the other hand, if the expected average waiting time is less than the threshold, it is considered that the number of users is relatively small, that is, the security is relatively low. The period may be the period during which direct operation is performed.

In addition to or in place of the predicted average waiting time, the implementation period calculation unit determines a period corresponding to the time zone in which the time when the alarm of the disturbance detection in building A is issued belongs to the non-stop operation of the elevator in building B. It may be calculated as a period. For example, if the time zone to which the alarm for the detection of the disturbance of building A is issued belongs to the time zone X (for example, 9:00 am to 9:00 pm) that is defined to have a relatively large number of users, then the period is relatively short. may be the period during which direct operation is implemented. On the other hand, if the time zone to which the time when the warning of the disturbance detection of the building A is issued belongs to other than the time zone X, a relatively long period may be set as the implementation period of the non-stop operation.

The situation notification unit 29 notifies the owner of the building B of the number of violent disturbances that have occurred in the vicinity of the building B (an example of a predetermined range based on the position of the building B) in the past certain period of time, Guidance on adding a riot detection option contract to the elevator maintenance contract may be provided. As a result, the owner of the building B can consider subscribing to the optional contract for the violence detection, referring to the situation of the violence detection in the vicinity of the building B.

Although one embodiment has been described above, this is an example for explaining the present invention, and is not intended to limit the scope of the present invention only to this embodiment. The invention can also be implemented in various other forms.
