[0025] Hereinafter, the embodiment will be described with reference to the drawings. In addition, the same reference numerals are given to the same elements in each figure, and repeated descriptions are omitted.

[0026] Implementation

[0027] 1. Structure of the maintenance management system for lift equipment

[0028] Figure 11 is a diagram showing the configuration of a disaster management system according to the present embodiment. The elevator equipment to which the disaster management system 100 according to the present embodiment is applied is the elevator 2. The elevator equipment may include, for example, an escalator, a moving walkway, or equipment attached thereto.

[0029] The elevator system 1 is a system including a plurality of elevators 2. Each elevator 2 is applied to a building having a plurality of floors, for example. A plurality of elevators 2 may be installed in one building. A shaft 3 for the elevators 2 is installed in the building. The shaft 3 is a long space in the vertical direction that extends over a plurality of floors. In this example, each elevator 2 is a traction elevator. In addition, the elevator system 1 may include a drum elevator, a hydraulic elevator, and the like, for example. The traction elevator has a traction machine 4, a main rope 5, a car 6, a counterweight 7, and a control panel 9.

[0030] The traction machine 4 has a motor that generates a driving force and a sheave that rotates by the driving force generated by the motor. The traction machine 4 is, for example, arranged at the upper part or the lower part of the hoistway 3. Alternatively, when a machine room is provided in the elevator 2, for example, above the hoistway 3, the traction machine 4 may also be arranged in the machine room.

[0031] The main rope 5 is a rope that supports the load 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 in a manner that pulls up one side of the sheave of the hoisting machine 4 by the driving force generated by the motor of the hoisting machine 4.

[0032] The car 6 is a device that transports passengers of the elevator 2 between multiple floors by running in the vertical direction 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 traction machine 4 on the other side of the sheave of the traction machine 4. As the main rope 5 is moved by the motor of the traction machine 4, the car 6 and the counterweight 7 run in the hoistway 3 in the vertical direction to the opposite sides.

[0033] The earthquake sensor 8 is a device that senses earthquake waves at a location where the elevator 2 is installed. The earthquake sensor 8 is disposed, for example, in the hoistway 3 or the like. Alternatively, when a machine room is installed, the earthquake sensor 8 may be disposed in the machine room.

[0034] The control panel 9 is a device for controlling the movement of the elevator 2. The movement of the elevator 2 includes, for example, the travel of the car 6. The control panel 9 is, for example, arranged at the upper part or the lower part of the shaft 3. Alternatively, when a machine room is provided, the control panel 9 may also be arranged in the machine room. The control panel 9 is connected to the equipment of the elevator 2 so as to obtain the state information of the elevator 2 for controlling the movement of the elevator 2. The control panel 9 obtains the state information of the elevator 2 from, for example, sensors or switches provided in the car 6, the traction machine 4 or the shaft 3 of the elevator 2. The control panel 9 obtains the sensing information of the seismic wave from the seismic sensor 8.

[0035] The control panel 9 responds to the earthquake based on the sensing information of the earthquake wave obtained from the earthquake sensor 8. The response to the earthquake includes, for example, a controlled operation or a stopped operation. The controlled operation is an automatic operation in response to the earthquake that has occurred. The controlled operation includes a diagnostic operation for diagnosing the effect of the earthquake on the elevator 2. The stopped operation is a response in which the car 6 is stopped and waited without running.

[0036] Each elevator 2 has 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 obtains the state information 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 obtains an abnormality signal from the control panel 9. Examples of such abnormalities include being trapped and abnormal door opening and closing.

[0037] A disaster management system 100 is applied to the elevator system 1. The disaster management system 100 performs maintenance management on the elevator 2 of the customer who has signed a maintenance contract when a disaster occurs. In the maintenance contract, the agreed implementation items to be implemented when an abnormality occurs in the elevator 2 are agreed. The disaster management system 100 is a system that manages the display of the list items of the agreed implementation items to be referred to by the operator when an abnormality occurs in the elevator 2 when a disaster occurs. The disaster management system 100 includes a central management device 13 and a list management device 15.

[0038] The central management device 13 is a device for remotely monitoring each elevator 2. The central management device 13 is, for example, arranged in an information center 16 or the like. The information center 16 is a base for collecting information of 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 to each remote monitoring device 11 through a telephone line such as LTE, for example, so as to be able to communicate the status of each elevator 2 during normal operation, etc.

[0039] The list management device 15 is a device that manages the display of the list items of the agreed implementation matters when some abnormality occurs in the elevator 2. The list management device 15 is, for example, configured in the information center 16. The list management device 15 is, for example, one or more server devices. The central management device 13 is connected to each remote monitoring device 11 through a telephone line such as LTE, so that abnormal signals of each elevator 2 can be communicated. The list management device 15 is connected to the central management device 13 through an internal network of a maintenance company. The list management device 15 is connected to a communication network such as the Internet or a telephone line network, so that disaster information from an external service 19 can be received. The external service 19 is, for example, an external service that releases 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.

[0040] The operator is a person who handles the agreed implementation items while checking the list. The operator has a terminal device 18. The terminal device 18 has 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, an intranet of the maintenance company.

[0041] As described above, in the maintenance contract with the customer, the agreed implementation items for each building are agreed upon. When an abnormality occurs in the customer's elevator 2, the operator is required to comply with these agreed implementation items. Therefore, the list management device 15 generates a list of agreed implementation items corresponding to the building where the abnormality occurs, and displays it on the operator's terminal device 18. This list is hereinafter referred to as a "TODO list".

[0042] As functional blocks related to the generation and management of the TODO list, the list management device 15 includes an abnormal signal receiving 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. The various functions of the list management device 15 will be described below with reference to specific examples.

[0043] 2. Functions of the list management device 15

[0044] 2-1. Display function of TODO list

[0045] The list management device 15 generates a TODO list by extracting list items of agreed implementation matters of the building in which the elevator 2 in which the abnormality occurred is installed. This process is hereinafter referred to as "list generation process".

[0046] Figure 2 2 is a diagram showing an example of building information. The building information is information for specifying a target elevator facility, and is composed of, for example, an identification number and a machine number assigned to each building. Figure 3This is a diagram showing an example of agreed implementation information. As shown in the diagram, the agreed implementation information corresponds the identification number, machine number, and abnormal signal category of the building to be the subject of the agreed implementation information to the classification and response content of the agreed implementation items. The abnormal signal category is a symbol for classifying abnormal signals, and is specified by the abnormal signal category master table as abnormal signal category information. Figure 4 2 is a diagram showing an example of an abnormal signal category master table. As shown in the figure, the abnormal signal category master table associates abnormal signal categories with abnormal contents such as being trapped in the elevator 2. The storage unit 22 stores building information, agreed implementation information, and the abnormal signal category master table.

[0047] The abnormal signal receiving unit 21 is a part that receives abnormal signals of the elevator 2 from each remote monitoring device 11. The abnormal signal includes the abnormal content of the elevator 2 and the building information that specifies the elevator 2. In the list generation process, the list generation unit 23 refers to the building information and specifies the building based on the abnormal signal received by the abnormal signal receiving unit 21. Then, the list generation unit 23 generates a TODO list by extracting the list items of the agreed implementation matters information corresponding to the specified building. Figure 5 2 is a diagram showing an example of a generated TODO list. The example shown in this diagram is a display example of a list generated when an abnormal signal is received from a building with identification number AA-XXX. The display unit 26 causes the operator's terminal device 18 to display the TODO list.

[0048] 2-2. Disaster scale determination function

[0049] The list management device 15 determines the scale of the disaster occurring in the area where the elevator 2 is installed. This process is hereinafter referred to as "disaster scale determination process". In the disaster scale determination process, the disaster scale information receiving unit 27 receives disaster scale information from the external service 19. The disaster scale determination unit 24 determines the scale of the disaster and its area based on the received disaster scale information. Figure 6 2 is a diagram showing an example of a master table of earthquake magnitude information. The master table of earthquake magnitude information is a disaster scale determination condition that associates the magnitude of the earthquake with the magnitude of the earthquake. The magnitude value here uses an index value that becomes larger as the disaster scale increases. The storage unit 22 stores Figure 6 The disaster scale determination unit 24 determines the level of the disaster scale corresponding to the magnitude information and the region included in the received disaster scale information.

[0050] Alternatively, in the disaster scale determination process, the list management device 15 determines the disaster scale based on the number of acceptances of received abnormality signals per unit time. Figure 72 is a diagram showing an example of an abnormal signal number master table. The abnormal signal number master table is a disaster scale determination condition that associates the level value of the disaster scale with the number of abnormal signals received per unit time as an indicator of the earthquake scale. The storage unit 22 stores Figure 7 The disaster scale determination unit 24 calculates the number of abnormal signals received by the abnormal signal receiving unit 21 per unit time, and determines the level of the disaster scale corresponding to the calculated number of signals.

[0051] 2-3. Display function of TODO list when disaster occurs

[0052] In the event of a large-scale disaster, the elevator 2 should be restored first, so it is sometimes difficult for the operator to deal with the TODO list in the same way as usual. Therefore, in the event of a disaster of a predetermined scale or larger, 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 the "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 the abnormal elevator 2 is installed, and sets the list items of the buildings with low priority to not be displayed. The priority here is, for example, a priority determined based on the attributes of the building.

[0053] Figure 8 This is a diagram showing building attribute information. Building attribute information is information in which attributes are registered in association with identification numbers of buildings. Fig. 9 : is a diagram showing a priority master table. The priority master table is priority information that registers priorities in correspondence with building attributes. The priority here is the priority of the urgency of the agreed implementation matters determined by the building attributes. Fig. 9 In the example shown, the priority of “hospital” is set to the highest value. The building attribute information and the priority master table are stored in the storage unit 22 .

[0054] In the list restriction process, the list restriction unit 25 displays list items of buildings having a priority level greater than or equal to a threshold value, and does not display list items of buildings having a priority level less than the threshold value. The priority threshold value here is, for example, "5".

[0055] Alternatively, in the list restriction process, the list restriction unit 25 sets the list items corresponding to the abnormal signal type requiring urgency to be displayed, and sets the other list items to be hidden. The abnormal signal type requiring urgency is, for example, abnormal signal type A corresponding to "trapped".

[0056] According to such list restriction processing, in a situation where priority is given to recovery in the event of a large-scale disaster, the operator can respond to list items with high urgency on a priority basis.

[0057] 3. Specific processing performed by the list management device 15

[0058] Fig.10 1 is a flowchart showing a routine of processing executed in the list management device 15. Fig.10 In step S100 of the routine shown, it is determined whether an abnormal signal has been received by the abnormal signal receiving unit 21. If the result is that the rejection determination is established, the routine ends, and if the approval determination is established, the process proceeds to step S102.

[0059] In step S102, a TODO list including list items of identification numbers of target buildings is generated based on the building information included in the abnormal signal. After the processing of step S102 is completed, the processing proceeds to step S104.

[0060] In step S104, it is determined whether a disaster of a predetermined level or higher has occurred. Figure 6 The magnitude information master table shown in FIG. 1 determines the level of the disaster scale corresponding to the magnitude received from the external service 19. Then, the disaster scale determination unit 24 determines whether the determined disaster scale level value is above a predetermined specified level. The specified level here is a threshold for determining whether the disaster scale is a large-scale disaster that should be restored with the highest priority. The specified level is set to "5", for example.

[0061] If the result of determination in step S104 is that the determination is made to be approved, the process proceeds to step S106, and if the determination is made not to be approved, the process proceeds to step S108. In step S106, the items with low priority among the list items of the TODO list generated in step S104 are set to be non-displayed. As an example, the list restriction unit 25 refers to the building attribute information and the priority master table to determine the priority corresponding to the building information included in the abnormal signal. Then, the list restriction unit 25 sets the list items corresponding to the buildings whose determined priorities are above the priority threshold to be displayed, and sets the list items corresponding to the buildings whose priorities are less than the priority threshold to be non-displayed.

[0062] Alternatively, as another example, the list restriction unit 25 refers to the abnormal signal number master table, sets list items corresponding to abnormal signal types requiring urgency, such as "trapped", to be displayed, and sets other list items to be hidden.

[0063] Alternatively, as another example, the list restriction unit 25 sets all list items corresponding to the building corresponding to the received abnormal signal to be non-displayed.

[0064] After the process of step S106 is completed, the process proceeds to step S108. In step S108, the display unit 26 displays the TODO list on the terminal device 18 of the operator.

[0065] According to the above processing, the display of the list items of the TDDO list when a large-scale disaster occurs can be limited, so the operator can give priority to the recovery work from the disaster. In addition, according to the above processing, the list items with high priority can be displayed in the TODO list, so both the improvement of customer satisfaction and the rapid recovery work from the disaster can be taken into account.

[0066] 4. Modifications

[0067] The disaster management system 100 of this embodiment may be applied in the following modified forms.

[0068] 4-1. Hardware resources of the disaster management system 100

[0069] Fig.11 1 is a diagram showing an example of hardware resources of the disaster management system 100. As hardware resources, the list management device 15 of the disaster management system 100 has a processing circuit 34 including a processor 30 and a memory 32. The processing circuit 34 may include a plurality of processors 30. The processing circuit 34 may also include a plurality of memories 32.

[0070] In this embodiment, the components shown by reference numerals 21 to 26 represent functions of the list management device 15. The functions of the storage unit 22 are implemented by the memory 32. The functions of the components shown by reference numerals 21 to 27 can be implemented by software, firmware, or a combination of software and firmware described as a program. The program is stored in the memory 32. The list management device 15 implements the functions of the components shown by reference numerals 21 to 27 by executing the program stored in the memory 32 by the processor 30 (computer).

[0071] The processor 30 is also called a CPU (Central Processing Unit), a central processing device, a processing device, an arithmetic device, a microprocessor, a microcomputer or a DSP. As the memory 32, a semiconductor memory, a magnetic disk, a floppy disk, an optical disk, a high-density disk, a mini disk or a DVD may also be used. The semiconductor memory that can be used includes a RAM, a ROM, a flash memory, an EPROM and an EEPROM.

[0072] Fig.12 FIG. 1 is a diagram showing another example of hardware resources of the disaster management system 100. Fig.12In the example shown, the list management device 15 has a processing circuit 34 including a processor 30 , a memory 32 and dedicated hardware 36 . Fig.12 This is an example in which a part of the functions of the list management device 15 is implemented by the dedicated hardware 36. All the functions of the list management device 15 may be implemented by the dedicated hardware 36. As the dedicated hardware 36, a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof can be used.

[0073] It is also possible to imagine a situation where there are still many list items even when the list items are limited in the list limitation process. Therefore, it is also possible to configure that, when the displayed list items exceed the predetermined upper limit, the list limitation unit 25 can further set the list items selected by the operator to not be displayed. With regard to such a structure, for example, the list limitation unit 25 can set the list items manually selected by the operator from the list items displayed on the terminal device 18 to not be displayed. According to such a structure, it is possible to take measures to further prioritize recovery from a disaster in the event of a large-scale disaster.

[0074] The following function may also be provided: when the recovery work from the disaster is completed, the operator can confirm the list items that are restricted from display. Fig.10 After step S108 of the routine shown, the list management device 15 determines whether the recovery work from the disaster is completed. For example, when the recovery rate of the elevators in the target area reaches a predetermined recovery rate, the list management device 15 determines that the recovery work from the disaster is completed. Then, when the determination is confirmed, the list restriction unit 25 sets the list items set not to be displayed to be displayed. The display unit 26 displays the TODO list set to be displayed on the operator's terminal device 18. According to such an additional function, the operator can confirm the TODO list set not to be displayed without omission.
