Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, common elements are denoted by the same reference numerals, and duplicate descriptions are omitted.

[0010] Embodiment. 1. Configuration of a Maintenance Management System for Elevator Equipment FIG. 1 is a diagram showing the configuration of the disaster management system according to the present embodiment. The elevator equipment to which the disaster management system 100 of the present embodiment is applied is an elevator 2. The elevator equipment may include, for example, an escalator, a moving walkway, or equipment associated therewith.

[0011] The elevator system 1 is a system including a plurality of elevators 2. Each elevator 2 is applied to, for example, a building having a plurality of floors. In one building, a plurality of elevators 2 may be provided. In the building, a hoistway 3 for the elevator 2 is provided. The hoistway 3 is a vertically long space extending over a plurality of floors. In this example, each elevator 2 is a traction type elevator. Note that the elevator system 1 may include, for example, a drum type elevator and a hydraulic elevator. The traction type elevator includes a hoisting machine 4, a main rope 5, a car 6, a counterweight 7, and a control panel 9.

[0012] The hoisting machine 4 includes a motor that generates a driving force and a sheave that rotates by the driving force generated by the motor. The hoisting machine 4 is disposed, for example, at the upper or lower part of the hoistway 3. Alternatively, when a machine room is provided above the hoistway 3 in the elevator 2, for example, the hoisting machine 4 may be disposed in the machine room.

[0013] The main rope 5 is a rope that supports the loads of the car 6 and the counterweight 7 in the hoistway 3. The main rope 5 is wound around the sheave of the hoisting machine 4. The main rope 5 supports the load of the car 6 on one side of the sheave of the hoisting machine 4. The main rope 5 supports the load of the counterweight 7 on the other side of the sheave of the hoisting machine 4. The main rope 5 moves so as to pull up one side of the sheave of the hoisting machine 4 by the driving force generated by the motor of the hoisting machine 4.

[0014] The car 6 is a device that transports passengers of the elevator 2 between multiple floors by traveling vertically in the hoistway 3. The counterweight 7 is a device that balances the load of the car 6 applied to one side of the sheave of the hoisting machine 4 on the other side of the sheave of the hoisting machine 4. The car 6 and the counterweight 7 travel in opposite directions in the hoistway 3 vertically as the main rope 5 moves by the motor of the hoisting machine 4.

[0015] The earthquake sensor 8 is a device that senses seismic waves at the location where the elevator 2 is provided. The earthquake sensor 8 is disposed, for example, in the hoistway 3 or the like. Alternatively, when a machine room is provided, the earthquake sensor 8 may be disposed in the machine room.

[0016] The control panel 9 is a device that controls the operation of the elevator 2. The operation of the elevator 2 includes, for example, the travel of the car 6. The control panel 9 is arranged, for example, at the upper or lower part of the hoistway 3. Alternatively, when a machine room is provided, the control panel 9 may be arranged in the machine room. The control panel 9 is connected to the devices of the elevator 2 so as to be able to acquire information on the state of the elevator 2 used for controlling the operation of the elevator 2. The control panel 9 acquires information on the state of the elevator 2 from, for example, sensors or switches provided in the car 6, the hoisting machine 4, or the hoistway 3 of the elevator 2. The control panel 9 acquires information on the detection of seismic waves from the seismic sensor 8.

[0017] Based on the information on the detection of seismic waves acquired from the seismic sensor 8, the control panel 9 responds to the earthquake. The response to the earthquake includes, for example, responses such as restricted operation or operation stop. The restricted operation is an automatic operation in response to the occurred earthquake. The restricted operation includes a diagnostic operation for diagnosing the influence of the earthquake on the elevator 2. The operation stop is a response in which the car 6 stops and waits without running.

[0018] Each elevator 2 is provided with a remote monitoring device 11. The remote monitoring device 11 is a device that monitors the state of the elevator 2. The remote monitoring device 11 acquires information on the state of the elevator 2 from, for example, the control panel 9. For example, when an abnormality occurs in the elevator 2, the remote monitoring device 11 acquires an abnormality signal from the control panel 9. Examples of such an abnormality include, for example, entrapment, door opening / closing abnormality, etc.

[0019] In the elevator system 1, the disaster management system 100 is applied. The disaster management system 100 manages the maintenance of the elevator 2 of customers with whom a maintenance contract has been made in the event of a disaster. In the maintenance contract, the agreed-upon implementation items to be carried out when an abnormality occurs in the elevator 2 are determined. The disaster management system 100 is a system that manages the display of the list items of the agreed-upon implementation items that an operator refers to when an abnormality occurs in the elevator 2 during a disaster. The disaster management system 100 includes a central management device 13 and a list management device 15.

[0020] The central management device 13 is a device that remotely monitors each elevator 2. The central management device 13 is arranged, for example, at the information center 16 or the like. The information center 16 is a base for collecting information on a plurality of elevators 2. The central management device 13 is, for example, one or more server devices or the like. The central management device 13 is connected from each remote monitoring device 11 through a telephone line such as LTE so as to be able to communicate the state of each elevator 2 during normal operation.

[0021] The list management device 15 is a device that manages the display of the list items of the agreed-upon implementation items when any abnormality occurs in the elevator 2. The list management device 15 is arranged, for example, at the information center 16 or the like. The list management device 15 is, for example, one or more server devices or the like. The central management device 13 is connected from each remote monitoring device 11 through a telephone line such as LTE so as to be able to communicate the abnormality signal of each elevator 2. The list management device 15 is connected to the central management device 13 through, for example, the intranet of the maintenance company. The list management device 15 is connected to a communication network such as the Internet or a telephone line network so as to be able to receive disaster information from the external service 19. The external service 19 is an external service that distributes disaster information such as earthquake information. The external service 19 is provided by, for example, a public institution such as the Japan Meteorological Agency or a similar institution in other countries, or a private institution.

[0022] An operator is a person who takes actions while checking the list of agreed-upon implementation items. The operator has a terminal device 18. The terminal device 18 is equipped with an input function for inputting information and a display function for displaying information. The terminal device 18 is connected to the list management device 15 through, for example, the intranet of a maintenance company.

[0023] As described above, in the maintenance contract with the customer, the agreed-upon implementation items for each building are determined. When an abnormality occurs in the customer's elevator 2, the operator is required to comply with these agreed-upon implementation items. Therefore, the list management device 15 generates a list of agreed-upon implementation items corresponding to the building where the abnormality occurred and displays it on the operator's terminal device 18. This list is hereinafter referred to as the "TODO list".

[0024] The list management device 15 includes an abnormality signal reception unit 21, a storage unit 22, a list generation unit 23, a disaster scale determination unit 24, a list restriction unit 25, and a display unit 26 as functional blocks related to the generation and management of the TODO list. Hereinafter, the various functions of the list management device 15 will be described with specific examples.

[0025] 2. Functions of the list management device 15 2-1. Display function of the TODO list The list management device 15 generates a TODO list by extracting the list items of the agreed-upon implementation items for the building where the abnormal elevator 2 is installed. This process is hereinafter referred to as the "list generation process".

[0026] FIG. 2 is a diagram showing an example of building information. The building information is information for specifying the target elevator equipment, and is composed of, for example, an identification number and a car number assigned to each building. FIG. 3 is a diagram showing an example of the agreed implementation item information. As shown in this figure, in the agreed implementation item information, the classification and corresponding content of the agreed implementation items are associated with the identification number of the target building, the car, and the abnormal signal type. The abnormal signal type is a symbol for classifying abnormal signals, and is defined by an abnormal signal type master as abnormal signal type information. FIG. 4 is a diagram showing an example of the abnormal signal type master. As shown in this figure, in the abnormal signal type master, the abnormal signal type is associated with the abnormal content such as entrapment of elevator 2. The storage unit 22 stores the building information, the agreed implementation item information, and the abnormal signal type master.

[0027] The abnormal signal reception unit 21 is a part that receives the abnormal signal of elevator 2 from each remote monitoring device 11. The abnormal signal includes the abnormal content of elevator 2 and the building information for specifying elevator 2. In the list generation process, the list generation unit 23 refers to the building information and identifies the building from the abnormal signal received by the abnormal signal reception unit 21. Then, the list generation unit 23 generates a TODO list by extracting the list items of the agreed implementation item information associated with the identified building. FIG. 5 is a diagram showing an example of the generated TODO list. In the example shown in this figure, it is a display example of the list generated when an abnormal signal is received from the building with the identification number AA-XXX. The display unit 26 causes the TODO list to be displayed on the operator's terminal device 18.

[0028] 2-2. Disaster scale determination function The list management device 15 determines the scale of a disaster that has occurred in the area where the elevator 2 is installed. This process is hereinafter referred to as the "disaster scale determination process". In the disaster scale determination process, the disaster scale information reception unit 27 receives disaster scale information from the external service 19. The disaster scale determination unit 24 determines the disaster scale and its area based on the received disaster scale information. FIG. 6 is a diagram showing an example of a seismic intensity information master. The seismic intensity information master is a disaster scale determination condition in which a rank value of the scale of an earthquake is associated with the magnitude of the seismic intensity. Here, as the rank value, an index value that becomes larger as the disaster scale is larger is used. The storage unit 22 stores the seismic intensity information master shown in FIG. 6. The disaster scale determination unit 24 identifies the rank of the disaster scale corresponding to the seismic intensity information included in the received disaster scale information and its area.

[0029] Alternatively, in the disaster scale determination process, the list management device 15 determines the disaster scale based on the number of received abnormal signals per unit time. FIG. 7 is a diagram showing an example of an abnormal signal number master. The abnormal signal number master is a disaster scale determination condition in which a rank value of the disaster scale is associated with the number of received abnormal signals per unit time, which is an index of the scale of an earthquake. The storage unit 22 stores the abnormal signal number master shown in FIG. 7. The disaster scale determination unit 24 calculates the number of signals per unit time of the abnormal signals received by the abnormal signal reception unit 21 and identifies the rank of the disaster scale corresponding to the calculated number of signals.

[0030] 2-3. Display function of the TODO list at the time of disaster occurrence When a large-scale disaster occurs, since it becomes necessary to prioritize the restoration of Elevator 2, it may become difficult for the operator to handle the TODO list in the same way as in normal times. Therefore, when a disaster of a scale equal to or greater than a predetermined scale occurs, the list restriction unit 25 restricts the list items of the TODO list generated in the list generation process. This process is hereinafter referred to as "list restriction process". In the first embodiment of the list restriction process, the list restriction unit 25 displays the list items of the buildings with high priority among the buildings where Elevator 2 with an abnormality has been installed, and sets the list items of the buildings with low priority to be non-displayed. The priority here is, for example, the priority determined from the attributes of the building.

[0031] FIG. 8 is a diagram showing building attribute information. The building attribute information is information in which an attribute is associated with a building identification number and registered. FIG. 9 is a diagram showing a priority master. The priority master is priority information in which a priority is associated with the attribute of the building and registered. The priority here is the priority of the urgency of the agreed-upon implementation items determined by the attribute of the building. In the example shown in FIG. 9, the priority of "hospital" is defined as the highest value. The building attribute information and the priority master are stored in the storage unit 22.

[0032] In the list restriction process, the list restriction unit 25, for example, displays the list items of the buildings with a priority equal to or higher than the threshold value, and makes the list items of the buildings with a priority lower than the threshold value non-displayed. The priority threshold value here is, for example, "5".

[0033] Alternatively, in the list restriction process, the list restriction unit 25, for example, sets the list items corresponding to the abnormal signal types that require urgency to be displayed, and sets the other list items to be non-displayed. The abnormal signal types that require urgency are, for example, abnormal signal type A corresponding to "being trapped".

[0034] According to such a list restriction process, in a situation where the restoration during a large-scale disaster is prioritized, the operator can preferentially handle the list items with high urgency.

[0035] 3. Specific Processes Executed in List Management Device 15 FIG. 10 is a flowchart showing a routine of a process executed in list management device 15. In step S100 of the routine shown in FIG. 10, it is determined whether abnormal signal reception unit 21 has received an abnormal signal. As a result, if the determination is not affirmed, this routine ends, and if the determination is affirmed, the process proceeds to step S102.

[0036] In step S102, based on the building information included in the abnormal signal, a TODO list including a list item of the identification number of the target building is generated. When the process of step S102 is completed, the process proceeds to step S104.

[0037] In step S104, it is determined whether a disaster equal to or greater than a predetermined rank has occurred. Here, disaster scale determination unit 24 specifies the rank of the disaster scale corresponding to the seismic intensity received from external service 19 with reference to the seismic intensity information master shown in FIG. 6. Then, disaster scale determination unit 24 determines whether the specified rank value of the disaster scale is equal to or greater than a predetermined specified rank. The specified rank here is a threshold for determining whether the disaster scale is a large-scale disaster for which restoration should be given top priority. The specified rank is set to, for example, "5".

[0038] As a result of the determination in step S104, if the determination is affirmed, the process proceeds to step S106, and if the determination is not affirmed, the process proceeds to step S108. In step S106, among the list items of the TODO list generated in step S104, items with a low priority are set to non-display. As an example, list restriction unit 25 refers to the building attribute information and the priority master to specify the priority corresponding to the building information included in the abnormal signal. Then, list restriction unit 25 sets the list items corresponding to the buildings with a specified priority equal to or higher than the priority threshold to display, and sets the list items corresponding to the buildings with a priority lower than the priority threshold to non-display.

[0039] Alternatively, as another example, the list restriction unit 25 refers to the abnormal signal number master, sets the list items corresponding to the abnormal signal types that require urgency represented by "containment", etc. to be displayed, and sets the other list items to be non-displayed.

[0040] Alternatively, as another example, the list restriction unit 25 sets all the list items associated with the building corresponding to the received abnormal signal to be non-displayed.

[0041] When the processing of step S106 is completed, the processing proceeds to step S108. In step S108, the display unit 26 displays the TODO list on the operator's terminal device 18.

[0042] According to the above processing, the display of the list items of the TDDO list when a large-scale disaster occurs can be restricted, so that the operator can prioritize the recovery work from the disaster. Also, according to the above processing, the list items with high priority can be displayed in the TODO list, so that both customer satisfaction improvement and rapid recovery work from the disaster can be achieved.

[0043] 4. Variation The disaster management system 100 of the present embodiment may be applied in a modified manner as follows.

[0044] 4-1. Hardware Resources of the Disaster Management System 100

[0045] FIG. 11 is a diagram showing an example of the hardware resources of the disaster management system 100. The list management device 15 of the disaster management system 100 includes a processing circuit 34 including a processor 30 and a memory 32 as hardware resources. A plurality of processors 30 may be included in the processing circuit 34. A plurality of memories 32 may be included in the processing circuit 34.

[0046] In the present embodiment, each part indicated by reference numerals 21 to 26 represents a function of the list management device 15. The function of the storage unit 22 is realized by the memory 32. The functions of each part indicated by reference numerals 21 to 27 can be realized by software described as a program, firmware, or a combination of software and firmware. The program is stored in the memory 32. The list management device 15 realizes the functions of each part indicated by reference numerals 21 to 27 by executing the program stored in the memory 32 by the processor 30 (computer).

[0047] The processor 30 is also referred to as a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. As the memory 32, a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD may be adopted. The adoptable semiconductor memories include RAM, ROM, flash memory, EPROM, and EEPROM, etc.

[0048] FIG. 12 is a diagram showing another example of the hardware resources of the disaster management system 100. In the example shown in FIG. 12, the list management device 15 includes a processing circuit 34 including a processor 30, a memory 32, and dedicated hardware 36. FIG. 12 shows an example in which a part of the functions of the list management device 15 is realized by the dedicated hardware 36. All of the functions of the list management device 15 may be realized by the dedicated hardware 36. As the dedicated hardware 36, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof can be adopted.

[0049] Even in a situation where list items are restricted in the list restriction process, a situation where there are still a large number of list items is also assumed. Therefore, when the number of displayed list items exceeds a predetermined upper limit, the list restriction unit 25 may be configured to be able to further set the list items selected by the operator to be non-displayed. Such a configuration is, for example, that the list restriction unit 25 may set the list items manually selected by the operator to be non-displayed from among the list items displayed on the terminal device 18. According to such a configuration, it becomes possible to give priority to further recovery from the disaster in the event of a large-scale disaster.

[0050] When the recovery work from the disaster has converged, it may have a function that allows the operator to confirm the list items whose display was restricted. Such a function is, for example, after step S108 of the routine shown in FIG. 10, the list management device 15 determines whether the recovery work from the disaster has converged. For example, the list management device 15 determines that the recovery work from the disaster has converged when the recovery rate of the elevators in the target area has reached a predetermined recovery rate. And when the establishment of the determination is recognized, the list restriction unit 25 sets the list items that were set to be non-displayed to be displayed. The display unit 26 displays the TODO list set to be displayed on the terminal device 18 of the operator. According to such an additional function, it becomes possible for the operator to confirm the TODO list set to be non-displayed without omission.
