Description

Technical Field

[0001] The present invention relates to an elevator system, and is suitable for application to, for example, an elevator system having a plurality of elevator devices under group control.

Background Art

[0002] In recent years, when a disaster occurs, such as an earthquake, flood, tsunami, or approaching typhoon, a regional information mass distribution service that mass-distributes emergency disaster reports to mobile communication terminals such as smartphones and dedicated receiving devices has been provided by each communication carrier, local public entity, etc.

[0003] Patent Document 1 discloses that when an emergency earthquake bulletin is received using such a regional information mass distribution service, the arrival time of the S-wave of the earthquake at the current location is predicted from the information on the epicenter and earthquake occurrence time included in the emergency earthquake bulletin, and based on the prediction result, controlling the earthquake-time completion operation of the elevator device.

[0004] Also in recent years, with the spread of the novel coronavirus infection, when a request for self-restraint from going out is issued to prevent infection based on the Special Measures Law for Countermeasures against New Influenza, etc., local public entities, communication carriers, etc. have started a service to mass-distribute that fact to the relevant area.

Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, in recent years, owners of buildings, employees of building management companies, etc. have become administrators of elevator devices installed in those buildings, and can freely set the display inside the elevator cars of those elevator devices or freely set functions of those elevator devices using their own computer devices or smartphones, and services have been provided.

[0007] In addition, examples of the "functions, etc. of the elevator device" that can be set here include, for example, setting of flood evacuation operation during flood occurrence, setting of control operation using earthquake early warning, service cut-off operation for specific floors, and operation suspension.

[0008] However, it is assumed that the administrators who perform such settings are not familiar with the operation management of the elevator device. And even if such an administrator receives an urgent report regarding a disaster or a request for self-restraint of going out, it is difficult to make judgments such as what settings should be made for the elevator device and whether any settings need to be made based on the distributed urgent report in the first place.

[0009] For example, when a flood warning is issued, it is difficult for an administrator who is not familiar with the operation of the elevator device to make judgments such as up to which floors the service should be provided from the top floor so as not to have a great impact on the business of the building and whether the elevator device should be set to flood evacuation operation in the first place.

[0010] Therefore, it is considered that if it is possible to present appropriate advice to the administrator according to the content of the urgently distributed report (regional information) regarding the settings of the elevator device capable of providing the above-mentioned services, it is possible to improve the safety of the elevator device while improving the convenience of the elevator device from the perspective of the administrator.

[0011] The present invention has been made in consideration of the above points, and intends to propose an elevator system capable of improving the safety of the elevator device while improving the convenience from the perspective of the administrator.

Means for Solving the Problems

[0012] In order to solve such problems, in the present invention, in an elevator system, a monitoring device that collects predetermined operation information regarding the operation state from an elevator device, and based on the operation information of the elevator device collected by the monitoring device, a control device that manages the elevator device, and a management terminal provided on the administrator side that notifies the control device that the emergency report has been received when the emergency report is received. When the control device is notified by the management terminal that the emergency report has been received, it determines the current operation state of the elevator device recognized based on the operation information collected by the monitoring device, and switches the operation mode of the elevator device from the first operation mode in normal times to the second operation mode according to the content of the emergency report as necessary. and the content before and after the change of the settings changed by the switching from the first operation mode to the second operation mode It is presented to the administrator via the management terminal. and the urgent notice is a request for self-restraint from going out for the prevention of the spread of infectious diseases, the first operation mode is an operation mode in which the door of the car is opened for a certain period of time for the next user and the inside of the car is ventilated while waiting without users, the second operation mode is an operation mode in which the opening time of the door in the first operation mode is extended, and the content before and after the change of the settings changed by the switching from the first operation mode to the second operation mode is the opening time of the door in the first operation mode and the second operation mode It is like this. Also, in the present invention, in an elevator system, there are provided a monitoring device that collects predetermined operation information regarding the operation state from an elevator device, a control device that manages the elevator device based on the operation information of the elevator device collected by the monitoring device, and a management terminal that is provided on the administrator side and notifies the control device that the urgent notice has been received when the urgent notice is received. When the control device is notified by the management terminal that the urgent notice has been received, the control device determines the current operation state of the elevator device recognized based on the operation information collected by the monitoring device, and switches the operation mode of the elevator device from the normal first operation mode to the second operation mode according to the content of the urgent notice as necessary based on the determination result, and presents the content before and after the change of the settings changed by the switching from the first operation mode to the second operation mode to the administrator via the management terminal. The urgent notice is a request for self-restraint from going out for the prevention of the spread of infectious diseases, the second operation mode is an operation mode that suppresses the maximum boarding rate of the car to a second boarding rate lower than the first maximum boarding rate allowed in the first operation mode, and the content before and after the change of the settings changed by the switching from the first operation mode to the second operation mode is the first maximum boarding rate in the first operation mode and the second boarding rate in the second operation mode. Furthermore, in the present invention, in an elevator system, there is provided a monitoring device that collects predetermined operation information regarding the operation state from an elevator device, a control device that manages the elevator device based on the operation information of the elevator device collected by the monitoring device, and a management terminal provided on the administrator side that notifies the control device when an emergency report is received. When the control device is notified by the management terminal that the emergency report has been received, it determines the current operation state of the elevator device recognized based on the operation information collected by the monitoring device, and switches the operation mode of the elevator device from the normal first operation mode to the second operation mode according to the content of the emergency report as necessary. The control device should present to the administrator, via the management terminal, the operation states of the elevator device before and after the change due to the switch from the first operation mode to the second operation mode. The emergency report is a request for self-restraint from going out to prevent the spread of infectious diseases. The second operation mode is an operation mode that adjusts the waiting time of users at each elevator hall to an appropriate waiting time. The operation states of the elevator device before and after the change due to the switch from the first operation mode to the second operation mode are the average waiting time of current users in the elevator hall and the waiting time of users expected in the elevator hall during the second operation mode.

Mode for Carrying Out the Invention

[0016] The following describes in detail an embodiment of the present invention with reference to the drawings.

[0017] (1) Configuration of the elevator system according to the present embodiment In FIG. 1, reference numeral 1 indicates an elevator system according to the present embodiment as a whole. This elevator system 1 includes a communication device 2, a management terminal 3, a control panel 4, a plurality of control panels 5, and a plurality of elevator devices 6 installed in the same building.

[0018] The communication device 2 is a communication terminal capable of communicating with an external device through a wired communication line such as the Internet or a wireless communication line such as a mobile phone line. The communication device 2 is connected to a remote monitoring center 7 via a network such as the Internet (not shown), and controls the communication protocol during communication with the remote monitoring center 7.

[0019] The management terminal 3 is a computer device provided with information processing resources such as a CPU (Central Processing Unit), a storage device, and a communication device. The management terminal 3 is provided on the administrator side for managing the elevator system 1, and is used by the administrator to manage the elevator system 1.

[0020] The management panel 4 is configured to include a management panel control device 8. The management panel control device 8 is a functional unit having a function of group managing an elevator device group 11 composed of a plurality of elevator devices 6. During normal operation, the management panel control device 8 controls the operation of each elevator device 6 via a control panel 5 that responds to optimize car allocation based on the operation information of the elevator device 6 transmitted from the control panel 5 of each elevator device 6.

[0021] Here, "optimization of car allocation" refers to a car allocation state in which the number of passengers in each elevator device 6 is below the rated capacity, the total weight inside the car (hereinafter referred to as the total weight inside the car) does not exceed the allowable weight, and the waiting time of users of the elevator device 6 in the elevator hall on each floor is minimized.

[0022] The control panel 5 is provided corresponding to each elevator device 6 constituting the elevator device group 11. This control panel 5 is configured to include a monitoring device 9 and a control panel control device 10.

[0023] The monitoring device 9 is a functional unit having a function of collecting various necessary information from the corresponding elevator device 6 and outputting the collected information to the control panel control device 10. In practice, the monitoring device 9 collects information such as, for example, the current position and state (ascending, descending, or stopped, etc.) of the car in the corresponding elevator device 6, the total weight and temperature inside the car, the operation state of the call buttons in the elevator hall on each floor, and the pressing state of the destination floor buttons on the operation panel inside the car, and outputs these collected information as the operation information of the elevator device 6 to the control panel control device 10 within its own control panel 5.

[0024] The control panel control device 10 is a functional unit having a function of controlling the operation of the corresponding elevator device 6 in accordance with the operation control instructions for group management given from the management panel 4. The control panel control device 10 periodically transmits the above-described operation information given from the monitoring device 9 to the management panel 4 or in response to a request from the management panel 4, and controls the operation of the corresponding elevator device 6 in accordance with such operation information and the above-described operation control instructions given from the management panel 4 based on the operation information.

[0025] Figure 2 shows the configuration of the management panel control device 8 in such an elevator system 1. As shown in this Figure 2, such a management panel control device 8 is configured to include a communication unit 20, a control unit 21, and a storage unit 22.

[0026] The communication unit 20 is a functional unit that performs protocol control during communication with the management terminal 3 and each control panel control device 10, and is composed of, for example, a NIC (Network Interface Card). The control unit 21 is a processor that controls the overall operation of the management panel control device 8, and is composed of, for example, a CPU or an MPU (Micro Processing Unit).

[0027] Furthermore, the storage unit 22 is composed of a semiconductor memory having a volatile memory area and a non-volatile memory area, and is used to temporarily and long-term hold various programs and data. The operation history management table 24 and the waiting number management table 25 described later are also stored and held in this storage unit 22. By the control unit 21 executing the program stored in the storage unit 22, various processes of the entire management panel control device 8 as described later are executed.

[0028] (2) Emergency Report Countermeasure Operation Function (2-1) Outline of the Emergency Report Countermeasure Operation Function and Configuration of Various Tables Next, the emergency report countermeasure operation function implemented in the management panel control device 8 of the elevator system 1 will be described. In the following description, a notice to that effect transmitted from the remote monitoring center 7 when a state of emergency declaration issued by the government due to the spread of infectious diseases, or a request for self-restraint from going out to prevent infection based on the Special Measures Law against New Influenza, etc., distributed by local public bodies or telecommunications carriers in response to the declaration of a state of emergency or focused measures for preventing the spread, etc., will be referred to as an "emergency report". Also, in the following description, when the management terminal 3 receives such an emergency report via the communication device 2, it is assumed that the fact is notified from the management terminal 3 to the management panel 4.

[0029] The emergency report countermeasure operation function implemented in such a management panel control device 8 is a function in which, when the management panel control device 8 is notified from the management terminal 3 that an emergency report has been received, the operation mode is switched from the normal operation mode to the operation mode for receiving an emergency report (hereinafter referred to as the emergency report countermeasure operation mode), the ventilation time described later is extended, the number of passengers getting on the car of each elevator device 6 is restricted, and the dispatching of each elevator device 6 is controlled so that the waiting time of users in elevator halls that are congested or where congestion is expected is minimized.

[0030] Note that the switching to the emergency report countermeasure operation mode is performed only when the owner of the elevator system 1 concludes a predetermined contract (hereinafter referred to as the emergency report countermeasure operation contract) with the maintenance company of the elevator device 6.

[0031] As a means for realizing such an emergency report countermeasure operation function, as shown in FIG. 2, an operation history management table 24 and a waiting number management table 25 are stored in the storage unit 22 of the management panel control device 8.

[0032] The operation history management table 24 is a table generated based on operation information periodically collected by the management panel control device 8 from the control panels 5 of each elevator device 6. Note that the collection of operation information for each elevator device 6 may be in a form where the management panel 4 periodically accesses each control panel 5 to obtain it, or in a form where each control panel 5 periodically transmits the operation information to the management panel 4 respectively.

[0033] This operation history management table 24 is used to manage the operation history of each elevator device 6. As shown in FIG. 3, corresponding to various information included in the operation information, it is configured to include a plurality of columns such as the unit number column 24A, the operation time column 24B, the departure floor column 24C, the arrival floor column 24D, the number of passengers column 24E, and the car interior temperature column 24F. In the operation history management table 24, one record (row) corresponds to the operation history information of one operation from when the car of any one elevator device 6 departs from any floor until it arrives at any floor.

[0034] And in the unit number column 24A, the unit number of the elevator device 6 corresponding to the operation history information is stored. Also, in the departure floor column 24C, the floor from which the car of the corresponding elevator device 6 departs is stored, and in the arrival floor column 24D, the floor at which the car arrives is stored.

[0035] Furthermore, in the operation time column 24B, the time when such a car departs from the departure floor is stored, and in the number of passengers column 24E, the number of users who were in the car at that time is stored. Note that the number of passengers is the number estimated by the management panel control device 8 based on the total weight inside the car given from the control panel control device 10 as operation information. Also, in the car interior temperature column 24F, the temperature inside the car measured by the thermometer installed in the car at that time (hereinafter, this is referred to as the car interior temperature) is stored.

[0036] Therefore, in the case of the example in FIG. 3, for example, "Elevator 1" operated from the "1st floor" to the "5th floor" at "13:05:30 on 11 / 1", and the number of passengers at that time was "3", and the car temperature at that time was shown to be "20.2°C".

[0037] The waiting number management table 25 is a table used to hold the number of users (hereinafter referred to as the waiting number) who were waiting for the arrival of the elevator car in the elevator hall on each floor, measured at regular time intervals in the past. As shown in FIG. 4, it is composed of a time column 25A and waiting number columns 25B provided corresponding to the elevator halls on each floor. In the waiting number management table 25, one record corresponds to the waiting number in the elevator hall on each floor measured at a certain time.

[0038] The time column 25A stores the time when the corresponding waiting number was measured, and each waiting number column 25B stores the waiting number in the elevator hall on the corresponding floor at that time. Note that the waiting number for each elevator hall is estimated or measured by the management board control device 8 through image processing based on video data transmitted in real time from cameras (not shown) installed in the elevator halls on each floor, and stored in the waiting number management table 25.

[0039] (2-2) Various processes related to the emergency report countermeasure operation function Next, the flow of various processes executed in the elevator system 1 in relation to such an emergency report countermeasure operation function will be described.

[0040] (2-2-1) Car allocation optimization process First, a series of processes (hereinafter referred to as the car allocation optimization process) executed in the elevator system 1 to optimize the car allocation by group management of each elevator device 6 when the elevator system 1 has not received an emergency report during normal times will be described.

[0041] FIG. 5 shows the flow of such vehicle allocation optimization processing. This vehicle allocation optimization processing starts at the timing when the power supplies of the control panels 5 and the management panel 4 of each elevator device 6 are first turned on after the installation of this elevator system 1, or at the timing when the power is turned on again after a planned power outage for maintenance.

[0042] And first, the monitoring device 9 and the control panel control device 10 of the control panel 5 of each elevator device 6 are started up (S1), and then, the management panel 4 is started up (S2). Subsequently, the management panel control device 8 of the management panel 4 collects the operation information of the corresponding elevator device 6 from each control panel 5 respectively (S3).

[0043] Next, the management panel control device 8 of the management panel 4 learns the operation history of each elevator device 6 and the number of waiting people on the elevator floors of each floor at that time based on the collected operation information (S4), and optimizes the vehicle allocation in the elevator device group 11 based on the learning result (S5). Furthermore, the management panel control device 8 waits for a certain period of time (S6), and then repeats the processes of steps S3 to S6.

[0044] By the above vehicle allocation optimization processing, the operation of each elevator device 6 constituting the elevator device group 11 is controlled so that the number of passengers in each elevator device 6 is below the rated capacity, the total weight in the car does not exceed the allowable weight, and the waiting time of the users of the elevator device 6 is minimized.

[0045] (2-2-2) Ventilation Time Extension Operation Processing On the other hand, FIG. 6 shows the flow of a series of processes (hereinafter referred to as ventilation time extension operation processing) executed by the management panel control device 8 of the management panel 4 notified of the reception of an emergency report from the management terminal 3.

[0046] In the present embodiment, as a normal operation mode of each elevator device 6, a ventilation operation mode in which the door of the car is opened for a certain period of time to ventilate the inside of the car for the next user during the standby state when there is no user is set in the control panel control device 10. Hereinafter, the operation state of the elevator device 6 in the ventilation operation mode is referred to as ventilation operation.

[0047] When the management panel control device 8 is notified of an emergency report from the remote monitoring center 7 along with the issuance of a request for self-restraint from going out, it determines the current operation state of each elevator device 6 based on the operation information collected from each control panel 5, and according to the determination result, if necessary, the operation mode of each elevator device 6 is set to an emergency report countermeasure operation mode in which the opening time of the car door in the ventilation operation (hereinafter referred to as ventilation time) is extended (hereinafter referred to as ventilation time extension operation mode), and it proposes to the administrator to switch to this mode.

[0048] In practice, when the management panel control device 8 is notified from the management terminal 3 that an emergency report has been received, it starts the ventilation time extension operation process shown in FIG. 6. First, it determines whether the owner of the elevator system 1 has concluded the above-mentioned emergency report countermeasure operation contract with the maintenance company of the elevator device 6 (S10).

[0049] In the present embodiment, if such an emergency report countermeasure operation contract has been concluded, it is assumed that the management terminal 3 holds the information. Therefore, the management panel control device 8 makes the determination in step S10 by inquiring the management terminal 3 whether such an emergency report countermeasure operation contract has been concluded. If the management panel control device 8 obtains a negative result in this determination, it determines to continue the current ventilation operation mode as the operation mode related to the ventilation operation of each elevator device 6 (S11), and then ends this ventilation time extension operation process.

[0050] On the other hand, when the management panel control device 8 obtains an affirmative result in the determination of step S10, it analyzes each operation history information stored in the operation history management table 24 (S12), and determines whether the boarding rate of each elevator car of the most recent elevator device 6 and the car interior temperature at that time are equal to or higher than normal (S13).

[0051] When the management panel control device 8 obtains an affirmative result in this determination, it determines whether the current operation mode of each elevator device 6 is the ventilation time extension operation mode (S14). Note that the operation state of the elevator device 6 in the ventilation time extension operation mode is referred to as the ventilation time extension operation.

[0052] When the management panel control device 8 obtains an affirmative result in this determination, it returns to step S12, and thereafter, executes the processes after step S12. Therefore, in this case, each elevator device 6 continues to operate in the normal ventilation operation mode.

[0053] On the other hand, when the management panel control device 8 obtains a negative result in the determination of step S14, it causes the ventilation time extension proposal screen 30 as shown in FIG. 7 to be displayed on the management terminal 3 (S15).

[0054] This ventilation time extension proposal screen 30 is a screen for proposing to the administrator that the ventilation time in the ventilation operation should be extended and the extension time, and includes a message display area 31, a current ventilation time display area 32, an infection prevention operation ventilation time display area 33, a check box 34, an "OK" button 35, and a "Cancel" button 36.

[0055] Then, in the message display area 31, a message is displayed asking the administrator whether to switch the operation of each elevator device 6 to the infection prevention operation (urgent rapid report countermeasure operation) because a request for self-restraint from going out has been issued.

[0056] In addition, in the fresh air replacement time display area 32, the replacement time during normal ventilation operation mode is displayed, and in the ventilation time display area 33 during infectious disease countermeasure operation, the optimized extended ventilation time calculated by the control panel control device 8 based on the analysis of the current ventilation time and the current operation status is displayed.

[0057] Note that the extended ventilation time during the execution of the ventilation countermeasure operation displayed in the ventilation time display area 33 during infectious disease countermeasure operation may be a preset time. Also, the ventilation time displayed in the ventilation time display area 33 during infectious disease countermeasure operation may be made changeable by the administrator to a desired time.

[0058] When the "Yes" button 35 is clicked on the ventilation time extension proposal screen 30, a response to that effect including the ventilation time during the execution of the infectious disease countermeasure operation displayed in the ventilation time display area 33 for infectious disease countermeasure operation at that time is transmitted from the management terminal 3 to the control panel control device 8 of the control panel 4. Also, when the "No" button 36 is clicked on the ventilation time extension proposal screen 30, a response to that effect is transmitted from the management terminal 3 to the control panel control device 8 of the control panel 4.

[0059] Note that on the ventilation time extension proposal screen 30, a check mark can be displayed in the check box 34 by clicking on the check box 34. By thus displaying a check mark in the check box 34, in the future, the ventilation time extension proposal screen 30 can be prevented from being displayed on the management terminal 3.

[0060] At this time, the control panel control device 8 waits for such a response to be transmitted from the management terminal 3. When it receives such a response, based on the content thereof, it determines whether or not the operation mode of each elevator device 6 should be shifted to the ventilation time extension operation mode (S16). And when the control panel control device 8 obtains a negative result in this determination (when the administrator clicks the "No" button 36 on the ventilation time extension proposal screen 30), it returns to step S12, and thereafter, executes the processing after step S12.

[0061] On the other hand, when the management panel control device 8 obtains an affirmative result in the determination in step S16 (when the administrator clicks the "Yes" button 35 on the ventilation time extension proposal screen 30), the management panel control device 8 should shift the operation mode of the elevator device 6 to the ventilation time extension operation mode in which the ventilation time is extended to the time included in the answer from the management terminal 3 to the proposal in step S15, and gives an operation control instruction to the control panel control device 10 of each control panel 5 respectively (S17). After that, it returns to step S12.

[0062] As a result, the control panel control device 10 of the control panel 5 of each elevator device 6 then switches the operation mode of the corresponding elevator device 6 to the ventilation time extension operation mode in which the ventilation time is extended to the time displayed in the ventilation time display area 33 during the infection prevention operation on the ventilation time extension proposal screen 30.

[0063] On the other hand, when the management panel control device 8 obtains a negative result in the determination in step S13, it determines whether the current operation mode of each elevator device 6 is the ventilation time extension operation mode (S18). And when the management panel control device 8 obtains a negative result in this determination, it returns to step S12, and then executes the processing after step S12.

[0064] On the other hand, when the management panel control device 8 obtains an affirmative result in the determination in step S18, it causes the management terminal 3 to display a ventilation time extension end proposal screen (not shown) for proposing to the administrator that the ventilation time extension operation mode should be terminated (S19). Thus, the administrator can specify whether to terminate such a ventilation time extension operation mode by a predetermined operation on this ventilation time extension end proposal screen. And at this time, the answer corresponding to the operation performed by the administrator on the ventilation time extension end proposal screen is notified from the management terminal 3 to the management panel 4.

[0065] At this time, the control device 8 of the control panel 4 is waiting for a response to be sent from the management terminal 3. When such a response is received, based on the content thereof, it is determined whether each elevator device 6 should terminate the ventilation time extension operation mode (S20). And when the control device 8 of the control panel obtains a negative result in this determination (when the administrator does not specify the end of the ventilation time extension operation mode on the ventilation time extension end proposal screen), it returns to step S12, and thereafter, executes the processes after step S12.

[0066] On the other hand, when the control device 8 of the control panel obtains an affirmative result in the determination of step S20 (when the administrator specifies the end of the ventilation time extension operation mode on the ventilation time extension end proposal screen), it gives an operation control instruction to each control panel 5 so as to shift the operation mode of each elevator device 6 to the normal ventilation operation mode (S21). As a result, the control device 10 of the control panel 5 of each elevator device 6 thereafter switches the operation mode of the corresponding elevator device 6 to the normal ventilation operation mode. And the control device 8 of the control panel returns to step S12, and thereafter, repeats steps S12 and subsequent steps in the same manner as described above.

[0067] (2-2-3) Riding rate adjustment operation process On the other hand, FIG. 8 shows the flow of a series of processes (hereinafter referred to as the riding rate adjustment operation process) that the control device 8 of the control panel 4 notified of receiving an emergency report from the management terminal 3 executes in parallel with the ventilation time extension operation process described above with respect to FIG. 6.

[0068] In the present embodiment, as the normal operation mode of each elevator device 6, the number of passengers in the car is suppressed to be less than or equal to the rated capacity of the car. When the total weight inside the car that is presumed to exceed the rated capacity is detected, getting off is bypassed, and departure is suppressed until the total weight inside the car becomes less than or equal to the rated capacity. A riding rate normal operation mode is set. Hereinafter, the operation state of the elevator device 6 in the riding rate normal operation mode is referred to as the riding rate normal operation.

[0069] When the management console control device 8 issues a request for self-restraint from going out, it determines the current operating state of each elevator device 6 based on the operation information collected from each control panel 5 according to the processing procedure shown in FIG. 8, and if necessary based on the determination result, the operation mode of each elevator device 6 is adjusted to a maximum occupancy rate lower than the maximum occupancy rate allowed during normal times (normal operation with occupancy rate), that is, the maximum occupancy rate of the car is suppressed to a lower occupancy rate (hereinafter referred to as the occupancy rate adjustment operation mode). It proposes to the administrator to switch to this mode.

[0070] In practice, when the management console control device 8 is notified from the management terminal 3 that an emergency report has been received, it starts the occupancy rate adjustment operation process shown in FIG. 8. First, it determines by inquiring the management terminal 3 whether the owner of the elevator system 1 has concluded the above-mentioned emergency report countermeasure operation contract with the maintenance company of the elevator device 6 (S30).

[0071] If the management console control device 8 obtains a negative result in this determination, it decides to continue the current occupancy rate normal operation mode as the operation mode regarding the occupancy rate of each elevator device 6 (S31), and ends this occupancy rate adjustment operation process. Therefore, in this case, the occupancy rate adjustment operation is not performed, and each elevator device 6 continues to operate in the occupancy rate normal operation mode.

[0072] On the other hand, if the management console control device 8 obtains an affirmative result in the determination of step S30, it analyzes the operation history information stored in the operation history management table 24 (FIG. 3) and the waiting number of people at each elevator hall of each floor stored in the waiting number management table 25 (FIG. 4) (S32), and determines whether the occupancy rate of each elevator device 6 in the recent past is equal to or higher than the normal occupancy rate (S33).

[0073] If the management console control device 8 obtains an affirmative result in this determination, it determines whether the current operation mode of each elevator device 6 is the occupancy rate adjustment operation mode (S34). Note that the operation state of the elevator device 6 in the occupancy rate adjustment operation mode is referred to as the occupancy rate adjustment operation.

[0074] When the management panel control device 8 obtains an affirmative result in this determination, it returns to step S32 and then executes the processes after step S32. Therefore, in this case, each elevator device 6 continues to operate in the normal occupancy rate operation mode.

[0075] On the other hand, when the management panel control device 8 obtains a negative result in the determination of step S34, it causes the management terminal 3 to display an occupancy rate adjustment proposal screen 40 as shown in FIG. 9 (S35).

[0076] This occupancy rate adjustment proposal screen 40 is a screen for proposing to the administrator that the maximum occupancy rate of the car should be suppressed, and is configured to include a message display area 41, a current maximum occupancy rate display area 42, a maximum occupancy rate display area 43 during infectious disease countermeasure operation, a check box 44, an "OK" button 45, and a "Cancel" button 46.

[0077] And in the message display area 41, a message is displayed asking whether to switch the operation of each elevator device 6 to infectious disease countermeasure operation (urgent rapid report countermeasure operation) because the car is crowded despite the issuance of a request for self-restraint from going out.

[0078] Also, in the current maximum occupancy rate display area 42, the maximum occupancy rate and the number of people of the car in the normal occupancy rate operation mode are displayed. In this case, the maximum occupancy rate in the normal occupancy rate operation mode is the occupancy rate when the maximum number of passengers as specified is on board, which is "100%". Also, in the maximum occupancy rate display area 43 during infectious disease countermeasure operation, the optimal maximum occupancy rate calculated by the management panel control device 8 based on the analysis of the current occupancy rate and the current operation status is displayed. This maximum occupancy rate is calculated to be a value lower than the maximum occupancy rate in the normal occupancy rate operation mode.

[0079] Note that the maximum occupancy rate displayed in the maximum occupancy rate display area 43 during infectious disease countermeasure operation may be a preset value. Also, the administrator may be able to change the maximum occupancy rate displayed in the maximum occupancy rate display area 43 to a desired value.

[0080] When the "Yes" button 45 is clicked on the passenger capacity adjustment proposal screen 40, an answer to that effect including the maximum passenger capacity during the infectious disease countermeasure operation, which was displayed in the maximum passenger capacity display area 43 for the infectious disease countermeasure operation at that time, is sent from the management terminal 3 to the control unit 8 of the control panel 4. Also, when the "No" button is clicked on the passenger capacity adjustment proposal screen 40, an answer to that effect is sent from the management terminal 3 to the control unit 8 of the control panel 4.

[0081] On the passenger capacity adjustment proposal screen 40, a check mark can be displayed in the check box 44 by clicking on the check box 44. By thus displaying a check mark in the check box 44, it is possible to prevent the passenger capacity adjustment proposal screen 40 from being displayed on the management terminal 3 in the future.

[0082] At this time, the control unit 8 of the control panel is waiting for such an answer to be sent from the management terminal 3. When it receives such an answer, it determines based on the content whether the operation mode of each elevator device 6 should be shifted to the passenger capacity adjustment operation mode (S36). If the control unit 8 of the control panel obtains a negative result in this determination, it returns to step S32 and then executes the processing after step S32.

[0083] On the other hand, if the control unit 8 of the control panel obtains an affirmative result in the determination in step S36, it gives an operation control instruction to the control unit 10 of each control panel 5 to the effect that the operation mode of the elevator device 6 should be shifted to the passenger capacity adjustment operation mode that suppresses the maximum passenger capacity of the car to the passenger capacity included in the answer from the management terminal 3 to the proposal in step S35 (S37), and then returns to step S32.

[0084] As a result, the control unit 10 of the control panel 5 of each elevator device 6 then switches the operation mode of the corresponding elevator device 6 to the passenger capacity adjustment operation mode that suppresses the maximum passenger capacity to the passenger capacity displayed in the maximum passenger capacity display area 43 for the infectious disease countermeasure operation on the passenger capacity adjustment proposal screen 40.

[0085] Thus, each control panel control device 10 then performs three levels of alert announcements according to the usage status of the elevator device 6 to suppress the maximum boarding rate in the car as part of the boarding rate adjustment operation. Further, when the total weight in the car measured by the weighing device installed in the car exceeds the threshold value set near the total weight in the car corresponding to the maximum boarding rate notified from the management panel control device 8, each control panel control device 10 starts the door closing operation even before the preset door opening time expires.

[0086] Furthermore, when the total weight in the car measured by the weighing device installed in the car exceeds the total weight in the car corresponding to the maximum boarding rate notified from the management panel control device 8, each control panel control device 10 prompts the user to get off by means of a buzzer sound or a voice message, etc., and suppresses the departure of the car until the total weight in the car becomes less than the total weight in the car corresponding to the maximum boarding rate notified from the management panel control device 8.

[0087] On the other hand, when obtaining a negative result in the determination of step S33, the management panel control device 8 determines whether the current operation mode of each elevator device 6 is the boarding rate adjustment operation mode (S38). If the management panel control device 8 obtains a negative result in this determination, it returns to step S32 and then executes the processing after step S32.

[0088] In contrast, when obtaining a positive result in the determination of step S38, the management panel control device 8 causes the management device to display a boarding rate adjustment end proposal screen (not shown) for proposing to the administrator that the boarding rate adjustment operation mode should be terminated (S39). Thus, the administrator can specify whether to terminate such a boarding rate adjustment operation mode by a predetermined operation on this boarding rate adjustment end proposal screen. Then, the answer corresponding to the operation performed by the administrator on the boarding rate adjustment end proposal screen at this time is notified from the management terminal 3 to the management panel 4.

[0089] At this time, the control device 8 of the control panel 4 is waiting for a response to be sent from the management terminal 3. When such a response is received, based on the content thereof, it determines whether each elevator device 6 should terminate the passenger load adjustment operation mode (S40). And when the control device 8 of the control panel obtains a negative result in this determination (when the administrator does not instruct the termination of the passenger load adjustment operation mode on the passenger load adjustment termination proposal screen), it returns to step S32, and thereafter, executes the processing after step S32.

[0090] On the other hand, when the control device 8 of the control panel obtains an affirmative result in the determination of step S40 (when the administrator instructs the termination of the passenger load adjustment operation mode on the passenger load adjustment termination proposal screen), it gives an operation control instruction to each control panel 5 so as to shift the operation mode of each elevator device 6 to the passenger load normal operation mode (S41). As a result, the control device 10 of the control panel 5 of each elevator device 6 thereafter switches the operation mode of the corresponding elevator device 6 to the passenger load normal operation mode. And the control device 8 of the control panel returns to step S32, and thereafter, repeats steps S32 and subsequent steps in the same manner as described above.

[0091] (2-2-4) Waiting time adjustment operation process FIG. 10 shows the flow of a series of processes (hereinafter referred to as waiting time adjustment operation processes) that are executed in parallel with the ventilation time extension operation process described above with respect to FIG. 6 and the passenger load adjustment operation process described above with respect to FIG. 8 by the control device 8 of the control panel 4 that has been notified of the reception of an emergency report from the management terminal 3.

[0092] In the present embodiment, as the normal operation mode of each elevator device 6, a waiting time minimization operation mode for collectively managing each elevator device 6 so that the waiting time in each elevator hall of each floor becomes minimum is set in the control device 8 of the control panel. Hereinafter, the operation state of the elevator device 6 in the waiting time minimization operation mode is referred to as waiting time minimization operation.

[0093] When the management console control device 8 issues a request for self-restraint from going out, it determines the current operating state of each elevator device 6 based on the operation information collected from each control panel 5, and proposes to the administrator to switch the operation mode of each elevator device 6 to an emergency report countermeasure operation mode (hereinafter referred to as a waiting time adjustment operation mode) that adjusts the waiting time in a congested elevator hall to an appropriate waiting time.

[0094] Actually, when the management console control device 8 is notified from the management terminal 3 that an emergency report has been received, it starts the waiting time adjustment operation process shown in FIG. 10. First, it determines by inquiring the management terminal 3 whether the owner of the elevator system 1 has concluded the above-mentioned emergency report countermeasure operation contract with the maintenance company of the elevator device 6 (S50).

[0095] If the management console control device 8 obtains a negative result in this determination, it decides to continue the current waiting time minimization operation mode as the operation mode regarding the waiting time of each elevator device 6 (S51), and ends this waiting time adjustment operation process.

[0096] On the other hand, if the management console control device 8 obtains an affirmative result in the determination in step S50, it analyzes the number of waiting people in each elevator hall of each floor stored in the waiting number management table 25 (S52), and determines whether the waiting time of the users in each recent elevator hall is equal to or more than the normal waiting time (S53).

[0097] If the control panel control device 7 obtains an affirmative result in this determination, it determines whether the current operation mode of each elevator device 6 is the waiting time adjustment operation mode (S54). Hereinafter, the operation state of the elevator device 6 in the waiting time adjustment operation mode will be referred to as the waiting time adjustment operation.

[0098] If the management console control device 8 obtains an affirmative result in this determination, it returns to step S52, and thereafter executes the processes after step S52. Therefore, in this case, each elevator device 6 continues to operate in the waiting time minimization operation mode.

[0099] On the other hand, when the management console control device 8 obtains a negative result in the determination of step S54, it causes the management device to display a waiting time adjustment proposal screen 50 as shown in FIG. 11 (S55).

[0100] This waiting time adjustment proposal screen 50 is a screen for proposing to the administrator that a waiting time adjustment operation should be performed to minimize the waiting time of users in the congested elevator hall, and includes a message display area 51, a current average waiting time display area 52, an expected waiting time display area 53 during the infectious disease countermeasure operation, a checkbox 54, an "OK" button 55, and a "Cancel" button 56.

[0101] Then, in the message display area 51, a message is displayed asking whether to switch the operation of each elevator device 6 to an infectious disease countermeasure operation (urgent information countermeasure operation) because the waiting time in the elevator hall has become long despite the issuance of a request for self-restraint from going out.

[0102] In addition, the current average waiting time display area 52 displays the average waiting time of users in the normal waiting time operation mode, and the expected waiting time display area 53 during the infectious disease countermeasure operation displays the expected value of the waiting time of users after the implementation of the waiting time adjustment operation predicted by the management console control device 8 based on the analysis of the current boarding rate and the current operation status.

[0103] Then, when the "OK" button 55 is clicked on the waiting time adjustment proposal screen 50, a response to that effect is transmitted from the management terminal 3 to the management console control device 8 of the management console 4. Also, when the "Cancel" button 56 is clicked on the waiting time adjustment proposal screen 50, a response to that effect is transmitted from the management terminal 3 to the management console control device 8.

[0104] In the waiting time adjustment proposal screen 50, by clicking the checkbox 54, a checkmark can be displayed within the checkbox 54. By thus displaying the checkmark within the checkbox 54, in the future, it is possible to prevent the waiting time adjustment proposal screen 50 from being displayed on the management terminal 3.

[0105] At this time, the panel control device 8 of the control panel 4 is waiting for such a response to be sent from the management terminal 3. When receiving such a response, based on the content thereof, it determines whether the operation mode of each elevator device 6 should be shifted to the waiting time adjustment operation mode (S56). And when the panel control device 8 obtains a negative result in this determination (when the administrator clicks the "No" button 56 on the waiting time adjustment proposal screen 50), it returns to step S52, and thereafter, executes the processes after step S52.

[0106] On the other hand, when the panel control device 8 obtains an affirmative result in the determination of step S56 (when the administrator clicks the "Yes" button 55 on the waiting time adjustment proposal screen 50), it shifts the operation mode of each elevator device 6 to the waiting time adjustment operation mode (S57), and thereafter, adjusts the car dispatching of each elevator device 6 so as to make the waiting time of users in the crowded elevator hall shorter than usual.

[0107] For example, when the panel control device 8 detects the crowded state inside the car of the elevator device 6 departing from a certain floor based on the operation information provided by each elevator device 6 (when the total car weight estimated to be more than a predetermined number of people is measured), since there is a high possibility that many users in a waiting state will occur at each elevator hall of the floors after the elevator hall of the departure floor of that elevator device 6, it is arranged to direct the car of another elevator device 6 to each elevator hall of the floors after the elevator hall of such a departure floor in advance, so as to suppress the crowding of users in these elevator halls.

[0108] Further, when the operation panel control device 8 frequently detects the crowded state inside the car of the elevator device 6 starting from a certain floor as described above, it estimates that the number of users waiting in the elevator hall on that floor is increasing, and increases the number of car dispatching to that floor.

[0109] On the other hand, when the operation panel control device 8 obtains a negative result in the determination of step S53, it determines whether the current operation mode of each elevator device 6 is the waiting time adjustment operation mode (S58). And when the operation panel control device 8 obtains a negative result in this determination, it returns to step S52, and thereafter, executes the processes after step S52.

[0110] On the contrary, when the operation panel control device 8 obtains an affirmative result in the determination of step S58, it causes a waiting time adjustment end proposal screen (not shown) for proposing to the administrator that the waiting time adjustment operation mode should be terminated to be displayed on the management terminal 3. Thus, the administrator can specify whether to terminate such a waiting time adjustment operation mode by a predetermined operation on this waiting time adjustment end proposal screen (S59). And at this time, a response corresponding to the operation performed by the administrator on the waiting time adjustment end proposal screen is notified from the management terminal 3 to the operation panel 4.

[0111] At this time, the operation panel control device 8 of the operation panel 4 waits for such a response to be transmitted from the management terminal 3, and when receiving such a response, determines based on the content thereof whether each elevator device 6 should terminate the waiting time adjustment operation mode (S60). And when the operation panel control device 8 obtains a negative result in this determination (when the administrator does not specify the termination of the waiting time adjustment operation mode on the waiting time adjustment end proposal screen), it returns to step S52, and thereafter, executes the processes after step S52.

[0112] On the other hand, when the management console control device 8 obtains an affirmative result in the determination in step S60 (when the administrator designates the end of the waiting time adjustment operation mode on the waiting time adjustment end proposal screen), the management console control device 8 gives an operation control instruction to each control panel 5 so that the operation mode of each elevator device 6 is shifted to the waiting time minimization operation mode (S61). As a result, the control panel control device 10 of the control panel 5 of each elevator device 6 then switches the operation mode of the corresponding elevator device 6 to the waiting time minimization operation mode.

[0113] Next, the management console control device 8 returns to step S52, and thereafter repeats steps S52 and subsequent steps in the same manner as described above.

[0114] (3) Effects of the present embodiment As described above, in the elevator system 1 of the present embodiment, when the management console control device 8 of the management console 4 is notified from the management terminal 3 that an emergency report has been transmitted from the remote monitoring center 7 along with the issuance of a request for self-restraint from going out, the management console control device 8 determines the current operation state of each elevator device 6 recognized based on the collected operation information, and proposes to the administrator via the management terminal 3 that the operation mode of each elevator device 6 should be switched from the normal operation mode to the emergency report countermeasure operation mode for preventing the spread of infectious diseases as necessary based on the determination result.

[0115] Therefore, according to the present elevator system 1, since an appropriate proposal can be made to the administrator at an appropriate timing, even when the administrator is not familiar with the operation management of the elevator device 6, the administrator can operate the elevator device 6 with high safety by following such a proposal. Thus, according to the present elevator system 1, it is possible to improve the safety of the elevator device 6 while improving the convenience from the administrator's perspective.

[0116] (4) Application to other emergency reports The present invention can also be applied when the content of the "urgent report" notified from the remote monitoring center 7 to each elevator system 1 is an alarm (earthquake alarm, flood alarm or tsunami alarm) that is simultaneously distributed to the local area from a local public body or a telecommunications carrier at the time of a disaster such as an earthquake, flood or tsunami, or information on the cancellation of these alarms.

[0117] As an example, when a flood warning is issued, a user may have difficulty determining how to set the flood evacuation operation. For example, even if the ascending and descending range of the car is restricted with the top floor as the reference floor, information is required on up to which floor the service should be provided so as not to have a great impact on the building's operations. Also, it is difficult to determine whether a building is constructed in a location where a flood evacuation operation is necessary in the first place. Therefore, in such a case, it is possible to advise the user on whether to execute the flood evacuation operation or not, and propose the ascending and descending range of the car when executing the flood evacuation operation that restricts the ascending and descending range of the car with the top floor as the reference floor.

[0118] Also, when an earthquake early warning is distributed, usually, the car of each elevator device 6 is in an emergency stop at the nearest floor by the emergency earthquake early warning control operation. However, in such a case, there is a problem that the user does not know how long the elevator device 6 should be stopped. There are also requests from building users to use the elevator device 6, and there is a situation where they want to resume the operation as soon as possible. In this case, since there may be a mixture of elevator devices 6 that can operate and elevator devices 6 that cannot operate depending on the damage state of the elevator device 6, it is proposed to the user which elevator device 6 may resume operation.

[0119] Also, depending on the configuration of the elevator system 1, there may be an operation in which the elevator device 6 operating on the upper floors and the elevator device 6 operating on the lower floors are separated. Even if either elevator device 6 is damaged, it is possible to propose a degraded operation by operating the undamaged elevator device 6 on all floors.

[0120] In addition, when an urgent typhoon approach warning is given from the remote monitoring center 7, it is also possible to propose advice to the user to avoid confusion by changing the operation based on the usage of the building. For example, by proposing through-running operation for several elevator devices 6 between the floor where a meeting is being held and the floor directly connected to the railway, it becomes possible to smoothly guide meeting participants to the railway boarding area.

[0121] Note that all of the above proposals are executed by the control device 8 of the control panel 4. In practice, when a flood warning is issued and an urgent warning corresponding thereto is notified from the remote monitoring center 7 to the management terminal 3 via the control device 8 of the control panel 4, a screen for inquiring whether to switch the operation mode of the elevator device 5 to the flood evacuation operation mode is displayed on the management terminal 3 according to the content of the urgent warning. At this time, the control device 8 of the control panel 4 also proposes to the administrator the ascending and descending range of the car with the top floor as the reference floor. Note that the ascending and descending range of this car may be set in advance.

[0122] Also, when an earthquake warning or a flood warning is lifted and an urgent warning corresponding thereto is notified from the remote monitoring center 7 to the management terminal 3 via the control device 8 of the control panel 4, based on the content of the urgent warning and the state of the elevator device 6 recognized based on various information of the corresponding elevator device 6 notified from the monitoring device 9, the control device 8 of the control panel 4 inquires whether to return the current operation mode of the elevator device 6 from the flood evacuation operation mode or the urgent earthquake warning utilization control operation mode to the normal operation mode as needed, or proposes to the administrator to switch the operation mode to the above-mentioned retreat operation.

[0123] (5) Other embodiments Note that in the above-described embodiments, the case where a plurality of elevator devices 6 are installed has been described, but the present invention is not limited thereto. The ventilation time extension operation process and the passenger occupancy rate adjustment operation process can be applied to an elevator system having only one elevator device 6.

[0124] In the above-described embodiment, the case where the control panel 4 simultaneously executes three processes of ventilation time extension operation processing, boarding rate adjustment operation processing, and waiting time adjustment processing to prevent congestion in the car and the elevator hall has been described. However, the present invention is not limited to this, and the control panel 4 may execute only at least one of these three processes.

[0125] Furthermore, in the above-described embodiment, the case where the present invention is applied to the elevator system 1 including a plurality of elevator apparatuses 6 has been described. However, the present invention is not limited to this, and the present invention can also be applied to an elevator system having one elevator apparatus 6. In this case, the function of the control device 8 of the control panel 4 may be mounted on the control device 10 of the control panel 5, and further, a control device having the function of the control device 8 of the control panel 4 may be provided in the control panel 5 separately from the control device 10.

Industrial Applicability

[0126] The present invention can be widely applied to an elevator system having one or more elevator apparatuses.
