Description

Technical Field

[0001] The present invention relates to an elevator monitoring system, an elevator monitoring method and a program. Background Art

[0002] Generally speaking, each device such as a hoist that drives and controls an elevator is operated by power supplied from a purchased power source including a commercial power source. However, in the event of a power outage caused by an earthquake or a fire, the power supply from the purchased power source is stopped, and the elevator stops driving. Therefore, if there are passengers in the elevator car, they may be trapped in the car.

[0003] In contrast, in the past, elevator systems are known to include an emergency power storage device that serves as a backup driving power source during a power outage, and an automatic parking device that stops the car at the nearest floor by supplying power from the power storage device. In the event of a power outage, the power storage device supplies power to the automatic parking device, and the automatic parking device moves the car up and down to the nearest floor. This can prevent passengers from being trapped in the elevator during a power outage.

[0004] Patent Document 1 discloses a configuration in which, when the power of an emergency power storage device of an elevator is exhausted, the drive control of the elevator is performed using the power of an emergency power storage device of an escalator adjacent to the elevator.

[0005] However, when the power of the emergency power storage device of the elevator is exhausted and the power supply to the power storage device in the building cannot be performed, the automatic parking operation of the automatic parking device cannot be performed. As in the invention disclosed in Patent Document 1, even if the structure can supply power from the power storage device of the escalator, when the power of the emergency power storage device of the elevator is exhausted, the power of the power storage device of the adjacent escalator may also be exhausted, and power supply to the elevator may not be performed.

[0006] Therefore, in this case, the automatic parking operation of the automatic parking device cannot be performed during a power outage, so the rescue of the passengers trapped in the elevator is implemented after waiting for the arrival of the maintenance personnel. Therefore, there is the following problem: after a power outage, it takes time from the occurrence of passengers being trapped in the elevator to the rescue.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2020-104955 Summary of the invention

[0008] Therefore, the present invention provides an elevator monitoring system, an elevator monitoring method, and a program that can quickly restore power at the site where the power outage occurs when a power outage occurs in a building in which an elevator system having a charging and power supply device is installed.

[0009] In order to solve the above problems and achieve the purpose of the present invention, the elevator monitoring system of the present invention monitors an elevator system, wherein the elevator system has: an elevator having a car traveling in an elevator passage; and a fault notification device, which notifies fault information of the elevator. The elevator monitoring system has: a fault notification receiving unit, which receives fault information including the power supply status to the elevator sent from the fault notification device; and an elevator information storage unit, which has an elevator specification information database, wherein the elevator specification information database stores elevator specification information related to whether the elevator system has a charging power supply device that can convert the power supplied from the electric vehicle into the power supplied to the elevator. In addition, there is a status determination unit, which determines the power supply status to the elevator having a fault based on the fault information received by the fault notification receiving unit, and determines whether the elevator system having the elevator having a fault has a charging power supply device based on the elevator specification information.

[0010] The elevator monitoring method of the present invention monitors an elevator system, wherein the elevator system comprises: an elevator having a car traveling in an elevator passage; and a fault reporting device, which reports fault information of the elevator, wherein fault information including the power supply status to the elevator sent from the fault reporting device is received, and based on the received fault information, the power supply status to the elevator having the fault is determined, and it is determined whether the elevator system having the elevator having the fault has a charging power supply device capable of converting the power supplied from an electric vehicle into the power supplied to the elevator.

[0011] In addition, the program of the present invention monitors an elevator system, which comprises: an elevator having a car traveling in an elevator passage; and a fault reporting device that reports fault information of the elevator, and the program is used to cause a computer to execute the following steps: a step of receiving fault information including a power supply status to the elevator; and a step of determining the power supply status to the elevator having a fault based on the received fault information, and determining whether the elevator system having the elevator having a fault has a charging power supply device capable of converting the power supplied from an electric car into power supplied to the elevator.

[0012] According to the present invention, when a power outage occurs in a building in which an elevator system having a charging and power supply device is installed, an electric vehicle can quickly go to the power outage site, and the elevator can be restored as soon as possible by power supply from the electric vehicle.

[0018] Hereinafter, an example of an elevator monitoring system, an elevator monitoring method, and a program according to an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, the present invention is not limited to the following examples. In each figure described below, the same reference numerals are given to common parts.

[0019] 1. First Implementation

[0020] 1-1. Elevator monitoring system

[0021] Figure 1 This is a block diagram showing an example of the functional structure of an elevator monitoring system 100 according to a first embodiment of the present invention (hereinafter referred to as the present embodiment). The elevator monitoring system 100 according to the present embodiment is a system that can dispatch an electric vehicle to a building where an elevator with an emergency battery that has been exhausted due to a power outage is installed, and supply power to the elevator from the electric vehicle. In the following description, the electric vehicle may also be referred to as a vehicle.

[0022] like Figure 1 As shown, the elevator monitoring system 100 of the present embodiment is composed of an elevator system 10 , a vehicle management system 5 , and a control system 4 .

[0023] [Elevator system]

[0024] The elevator system 10 is a system constructed in a building, and is composed of an elevator 1, a fault notification device 2, and a charging and power supply device 3. Although not shown in the figure, the elevator 1 has a car set in a hoistway of the building, a main rope installed at one end of the car, and a counterweight installed at the other end of the main rope and suspended in the hoistway. In addition, the elevator 1 has a hoisting machine around which the main rope is wound. The hoisting machine is rotatably installed in a machine room provided at the upper part of the hoistway, for example. The hoisting machine is controlled and driven by an elevator control unit not shown in the figure. As a result, the car is raised and lowered relative to the counterweight.

[0025] The elevator 1 of this embodiment is normally driven by the power supply from the commercial power supply. On the other hand, in the event of a power outage, emergency operation is performed by the power supply from the charging and power supply device 3. In addition, the elevator 1 of this embodiment has an automatic parking device (not shown) that performs parking operation to the nearest floor by the power supply from the charging and power supply device 3 when passengers are trapped in the car during a power outage.

[0026] The fault reporting device 2 automatically obtains the fault information of the elevator 1 based on the signal from the elevator control unit (not shown), and transmits the fault information to the control system 4. In the present embodiment, as the information obtained by the fault reporting device 2, for example, the power supply status to the elevator 1, the information related to the passengers trapped in the car of the elevator 1, etc. can be cited. When the operation of the elevator 1 is stopped urgently for some reason, the fault information is automatically obtained in the fault reporting device 2, and then transmitted from the fault reporting device 2 to the control system 4 via a communication line such as a public line and the Internet.

[0027] The charging and power supply device 3 is installed in the building where the elevator 1 is installed, and supplies the power required by the elevator 1 during a power outage. The charging and power supply device 3 charges the battery (not shown) with the power of the solar power generation device installed on the roof of the building where the elevator 1 is installed and the regenerative power accompanying the braking for stopping the elevator 1. In addition, the charging and power supply device 3 also functions as a power supply device that supplies the power supplied from the electric car 6 to the elevator 1 side. As the charging and power supply device 3, for example, an H-PCS (Hybrid Power Conditioning System) that integrates a solar power generation device and a power storage device can be cited.

[0028] [Control System]

[0029] The control system 4 is a system installed in a control center (not shown) that uniformly manages the registered elevators 1, and includes, for example, a fault notification receiving unit 41, a status determination unit 45, a screen control unit 43, a screen display unit 44, a vehicle search unit 46, a vehicle information receiving unit 47, and an elevator information storage unit 42.

[0030] The fault notification receiving unit 41 receives the fault information of the elevator 1 transmitted from the elevator system 10. Specifically, the fault notification receiving unit 41 receives the power supply status to the elevator 1 in which the fault occurred and the information on the car of the elevator 1 in which the passengers are trapped.

[0031] The state determination unit 45 determines the state of the elevator 1 based on the failure information of the elevator 1 received by the failure notification receiving unit 41 and the information stored in the elevator information storage unit 42 described later.

[0032] The vehicle information receiving unit 47 receives vehicle information transmitted from the vehicle management system 5 described later. Specifically, the vehicle information transmitted to the vehicle information receiving unit 47 includes the use status of each vehicle (the electric vehicle 6 in this embodiment) registered in the vehicle management system 5, the information of the user using the vehicle, and the location information of the vehicle used. The vehicle information received by the vehicle information receiving unit 47 is transmitted to the vehicle search unit 46.

[0033] The vehicle search unit 46 searches for available vehicles based on the information of the elevator 1 that has experienced a power outage and the vehicle information received by the vehicle information receiving unit 47. Specifically, the available vehicle 6 searched by the vehicle search unit 46 is a vehicle that can be dispatched to the building (power outage site) where the elevator 1 that has experienced a power outage is installed.

[0034] The screen control unit 43 controls the image displayed on the screen display unit 44 based on the determination result of the situation determination unit 45. In addition, the screen control unit 43 controls the image displayed on the screen display unit 44 based on the search result of the vehicle search unit 46.

[0035] The screen display unit 44 is composed of, for example, a liquid crystal display, and in addition to the display function, has a keyboard function (input function) capable of inputting numbers and character information like a tablet terminal or a smart phone. The screen display unit 44 displays information based on the determination result of the situation determination unit 45 and information related to the vehicle searched by the vehicle search unit 46 under the control of the screen control unit 43.

[0036] The elevator information storage unit 42 stores various pieces of information including an elevator position information database (DB) 421 , an elevator specification information database (DB) 422 , a business office information database (DB) 423 , and a management company information database (DB) 424 .

[0037] The elevator location information DB 421 is a database storing information including the address of the building where the registered elevator 1 is installed. The elevator specification information DB 422 is a database storing information related to the specifications of the elevator system 10 having the registered elevator 1. More specifically, the specification information of the elevator system 10 includes information on whether the charging power supply device 3 capable of converting the power supplied from the electric car 6 into the power supply of the elevator 1 is provided.

[0038] The business office information DB 423 is a database storing information of the business office in charge of the maintenance and inspection of each elevator 1 registered in the control system 4. More specifically, the information of the business office includes information such as the contact information and address of each business office. The management company information DB 424 is information of the management company that manages each elevator 1, and is a database storing information such as the contact information, address, and name of the person in charge of each management company.

[0039] [Vehicle Management System]

[0040] The vehicle management system 5 is a system installed in a control center or other management center for managing vehicles. The vehicle management system 5 manages the vehicle information of each business office that performs maintenance inspection of the elevator 1, and manages the information of the vehicles (electric vehicles 6) owned by each business office. In this embodiment, the vehicle management system 5 includes: a vehicle use registration unit 51, a vehicle user registration unit 52, a vehicle information transmission unit 54, a vehicle position acquisition unit 55, and a vehicle information storage unit 53.

[0041] The vehicle use registration unit 51 registers the input use status of the vehicle 6 owned by each business office in a vehicle use information database (DB) 531 described later. The vehicle user registration unit 52 registers the input information on the user of the vehicle 6 in a user information database (DB) 532 described later.

[0042] The vehicle information storage unit 53 includes a vehicle use information database (DB) 531 and a user information database (DB) 532. The vehicle use information database (DB) 531 is a database storing information related to the current use status of the vehicle 6, and is updated at any time based on the information registered in the vehicle use registration unit 51. The user information database (DB) 532 is a database storing information related to the user currently using the vehicle 6, and is updated at any time based on the information registered in the vehicle user registration unit 52. In addition, in the vehicle information storage unit 53, each registered vehicle 6 is stored in a state associated with an identifier (ID) of a business office that owns (manages) each vehicle 6.

[0043] The vehicle position acquisition unit 55 acquires the current position information of the vehicle 6 based on the information sent from the position information transmission unit 61 of the electric vehicle (vehicle) 6 registered in the vehicle management system 5. In addition, the position information transmission unit 61 of the electric vehicle 6 transmits the position information acquired from GPS or the like to the vehicle position acquisition unit 55 via a communication line such as the Internet.

[0044] The vehicle information transmitting unit 54 transmits information on the vehicle 6 owned (managed) by the business office to the control system 4 based on the information on the business office transmitted from the control system 4 .

[0045] The above is a description of the functional structures of the elevator monitoring system 100 of the present embodiment. These functional structures are implemented by information processing devices (hardware) such as microcontrollers constituting each system, and the information processing devices constituting each system have, for example, a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), and non-volatile memory respectively connected to the bus.

[0046] The CPU reads the program code of the software that implements each function of the present embodiment from the ROM in each system or each device constituting each system, expands it in the RAM and executes it. In addition, the information processing device may also have a processing device such as an MPU (Micro-Processing Unit) instead of the CPU. Variables, parameters, etc. generated in the middle of the operation processing are temporarily written in the RAM.

[0047] As the nonvolatile memory, for example, HDD (Hard Disk Drive), SSD (Solid State Drive), floppy disk, optical disk, magneto-optical disk, CD-ROM, CD-R, magnetic tape, nonvolatile memory card, etc. can be used. In addition to OS (Operating System), the nonvolatile memory also stores programs and data required for the CPU to operate. The nonvolatile memory corresponds to the elevator information storage unit 42 of the control system 4 and the vehicle information storage unit 53 of the vehicle management system 5, and also corresponds to a storage unit (not shown) configured in the elevator system 10. In addition, the program can also be stored in the ROM.

[0048] The program is stored in the form of program codes readable by the CPU, and the CPU sequentially executes operations according to the program codes. That is, ROM or nonvolatile memory is used as an example of a non-transitory recording medium readable by the CPU that stores the program executed by the CPU.

[0049] 1-2. Elevator monitoring method

[0050] Next, the processing procedure of the elevator monitoring method implemented in the elevator monitoring system 100 of the present embodiment will be described. Figure 2 This is a flowchart showing a process procedure executed by the control system 4 in the elevator monitoring system 100.

[0051] The fault notification receiving unit 41 receives the fault information including the emergency stop information of the elevator 1 in the building where the elevator 1 is installed from the fault notification device 2 of the elevator system 10. Figure 2 Flowchart of the process.

[0052] First, the fault notification receiving unit 41 receives information on the power supply status to the elevator 1 and whether or not a passenger is trapped in the car of the stopped elevator 1 from the fault notification device 2 on the elevator system 10 side (step S101).

[0053] Next, the status determination unit 45 determines whether the power supply to the elevator 1 is stopped based on the information received in step S101 (step S102). For example, when the power supply from the commercial power supply or the charging and power supply device 3 used during a power outage is stopped, the determination result in step S102 is "yes". In addition, when the power supply from the commercial power supply is stopped due to a power outage and the elevator system 10 does not have the charging and power supply device 3, the determination result in step S102 is also "yes".

[0054] On the other hand, when it is determined that electric power is being supplied from the commercial power supply or the charging and power supply device 3 used during a power outage, the determination in step S102 is “NO”.

[0055] If the determination result in step S102 is "No", the process proceeds to step S107. In step S107, the screen control unit 43 controls the screen display unit 44 according to the determination result in step S102. As a result, the screen display unit 44 of the control system 4 displays that a trap due to non-power outage has occurred. Then, Figure 2 The process shown ends.

[0056] If it is determined to be "yes" in step S102, the process proceeds to step S103. In step S103, the situation determination unit 45 obtains information on the corresponding elevator system 10 from the elevator specification information DB422 stored in the elevator information storage unit 42. Here, the information on the corresponding elevator system 10 is extracted from the elevator specification information DB422 based on the identification number of the elevator 1 sent from the fault reporting device 2.

[0057] Next, the situation determination unit 45 determines whether the corresponding elevator system 10 has a charging and power supply device 3 based on the information obtained in step S103 (step S104). If the determination in step S104 is "No", that is, if the corresponding elevator system 10 does not have a charging and power supply device 3, the process proceeds to step S106. In step S106, the screen control unit 43 controls the screen display unit 44 based on the determination result in step S104, and displays on the screen display unit 44 that a trapped state due to a power outage has occurred.

[0058] On the other hand, if the determination result in step S104 is "yes", that is, if it is determined that the corresponding elevator system 10 has the charging and power supply device 3, the process proceeds to step S105. In step S105, the screen control unit 43 controls the screen display unit 44 according to the determination result in step S104, and displays on the screen display unit 44 that the person is trapped due to the power outage and that the electric vehicle 6 can be rescued as soon as possible by connecting it to the charging and power supply device 3.

[0059] Thus, in this embodiment, when the elevator system 10 in which the trapped person is located has the charging and power supply device 3 and the power of the charging and power supply device 3 is exhausted, the result is determined as "yes" in step S104. Thus, the administrator of the control center in which the control system 4 is installed can be provided with information that the trapped passengers can be rescued as soon as possible by dispatching the electric car 6.

[0060] On the other hand, when the trapping in the elevator system 10 is not caused by the stop of the power supply, and when the charging and power supply device 3 itself is not installed in the elevator system 10 where the trapping occurs, the information of step S106 and step S107 is displayed. Thus, the control center can request the business office in charge of the maintenance and inspection of the corresponding elevator system 10 to dispatch a maintenance personnel to the building where the elevator 1 where the trapping occurs is installed.

[0061] Next, Figure 2 The process executed on the control system 4 side when the determination in step S104 of the process is "Yes" will be further described. Figure 3 It means in Figure 2 Flowchart of the vehicle search process executed after the determination of "yes" in step S104. That is, Figure 3 The flowchart is in Figure 2 It starts after a "yes" determination is made in step S104.

[0062] First, the vehicle search unit 46 confirms that a entrapment due to a power outage has occurred in the elevator system 10 including the charging and power supply device 3 based on the determination result of the situation determination unit 45 in step S104 (step S201 ).

[0063] Next, the vehicle search unit 46 extracts information related to the corresponding elevator system 10 from the elevator information storage unit 42 (step S202). Here, the identifier (ID) of the business office responsible for the maintenance and inspection of the corresponding elevator system 10 and the contact information of the responsible business office are extracted from the business office information database (DB) 423 of the elevator information storage unit 42.

[0064] Next, the vehicle search unit 46 extracts the usage status of the vehicle 6 owned by the responsible business office from the vehicle management system 5 based on the identifier (ID) of the responsible business office extracted in step S202 (step S203). In step S203, first, the identifier (ID) of the responsible business office is sent from the control system 4 side to the vehicle management system 5 side via the vehicle information receiving unit 47. Next, the vehicle information sending unit 54 extracts the usage status and user information of the vehicle 6 owned by the responsible business office from the vehicle usage information database (DB) 531 and the user information database (DB) 532 of the vehicle information storage unit 53 based on the identifier (ID) of the responsible business office. Thereafter, the vehicle information sending unit 54 sends the extracted information to the control system 4 side.

[0065] In step S202, the vehicle utilization status extracted may be the use or non-use of the vehicle 6 or the number of vehicles currently not in use. In this embodiment, the case of extracting the number of vehicles currently not in use is described as an example. As described above, the control system 4 can obtain information on the vehicles 6 owned (managed) by the business office in charge of the maintenance and inspection of the corresponding elevator system 10.

[0066] Next, the screen control unit 43 controls the screen display unit 44 based on the information extracted in step S202 and step S203, and displays the various information extracted in step S202 and step S203 on the screen display unit 44. Here, the information displayed on the screen display unit 44 is the identifier (ID) of the responsible business office, the contact information of the responsible business office, and the utilization status of the vehicles 6 owned by the responsible business office (the number of unused vehicles).

[0067] Thus, in the present embodiment, the information of the responsible business office responsible for the maintenance and inspection of the elevator system 10 where the power outage has occurred and the utilization status of the vehicles 6 owned by the responsible business office can be presented on the screen display unit 44 of the control system 4. When the controller of the control center confirms that there are unused vehicles 6 in the responsible business office based on the information displayed on the screen display unit 44, the controller can make a request to the responsible business office to dispatch the unused vehicles 6 to the elevator system 10 where the power outage has occurred. Thus, when a person is trapped due to the power outage in the elevator system 10 having the charging and power supply device 3, a vehicle 6 that can supply power can be quickly dispatched from the responsible business office. As a result, power can be supplied from the electric car 6 to the charging and power supply device 3, and the trapped passengers can be rescued as soon as possible.

[0068] 2. Second Embodiment (Example with Different Vehicle Search Method)

[0069] Next, an elevator monitoring method according to a second embodiment of the present invention will be described. Figure 41 is a flowchart showing a vehicle search method according to a second embodiment of the present invention. In the second embodiment, the process of vehicle search performed in the case of a trapped vehicle due to a power outage in an elevator system 10 having a charging and power supply device 3 is different from that in the first embodiment. Figure 2 The processing procedure executed after the determination of "yes" in step S104 is different from that in the first embodiment. In addition, the functional structure of the elevator monitoring system 100 is the same as that in the first embodiment, so it is omitted from the illustration and the repeated description is omitted.

[0070] First, the vehicle search unit 46 confirms that a power outage has occurred in the elevator system 10 including the charging and power supply device 3 based on the determination result of the situation determination unit 45 in step S104 (step S301).

[0071] Next, the vehicle search unit 46 extracts information related to the corresponding elevator system 10 from the elevator information storage unit 42 (step S302). Here, the identifier (ID) of the business office responsible for the maintenance and inspection of the corresponding elevator system 10 and the contact information of the responsible business office are extracted from the business office information database (DB) 423 of the elevator information storage unit 42. In addition, the location of the elevator system 10 where the power outage occurred on the map is extracted from the elevator location information database (DB) 421 of the elevator information storage unit 42.

[0072] Next, the vehicle search unit 46 extracts information on vehicles in use among the vehicles 6 owned by the responsible office from the vehicle management system 5 based on the identifier (ID) of the responsible office extracted in step S302 (step S303 ).

[0073] In step S303, first, the identifier (ID) of the responsible business office is sent from the control system 4 to the vehicle management system 5 side via the vehicle information sending unit 54. Next, the vehicle information sending unit 54 obtains the vehicle information in use from the vehicle use information database (DB) 531 of the vehicle information storage unit 53 based on the identifier (ID) of the responsible business office, and obtains the user information of the vehicle in use from the user information database (DB) 532. In addition, in the vehicle management system 5, the vehicle position acquisition unit 55 obtains the position information of the vehicle in use sent from the position information sending unit 61 provided in each vehicle 6. In addition, the vehicle information sending unit 54 sends the vehicle information in use, the user information (name, contact information) of the vehicle 6 in use, and the position information of the vehicle 6 in use to the control system 4 side.

[0074] Next, the vehicle search unit 46 determines whether there is a vehicle 6 in use within a certain range (within a distance) from the position on the map where the corresponding elevator system 10 is installed, based on the position information of the elevator system 10 and the information of the vehicle 6 in use (step S304). If the determination result in step S304 is "No", that is, if it is determined that there is no vehicle in use within a certain range from the position of the target elevator system 10, the process proceeds to step S307.

[0075] In step S307, the screen control unit 43 controls the screen display unit 44 based on the determination result of step S304 to display a map centered on the location where the corresponding elevator system 10 is installed and a message that there is no vehicle 6 in use nearby.

[0076] On the other hand, when it is determined to be "YES" in step S304, that is, when it is determined that there is a vehicle 6 in use within a certain range (distance) from the position of the corresponding elevator system 10, the process proceeds to step S305.

[0077] In step S305, when the vehicle search unit 46 detects a plurality of vehicles 6 existing within a certain range from the position on the map where the corresponding elevator system 10 is installed, the vehicle search unit 46 sorts the vehicles in the order of proximity to the installation position of the corresponding elevator system 10 (step S305). When only one vehicle 6 is detected, no sorting is performed.

[0078] Next, the screen control unit 43 controls the screen display unit 44 based on the information obtained in step S304 and step S305, and displays information about the vehicles 6 that can go to the power outage site of the elevator 1. Here, the screen display unit 44 displays, for example, a map centered on the location where the corresponding elevator system 10 is installed and the location of the vehicle 6 on the map within a predetermined range from the location on the map of the corresponding elevator system 10 under the control of the screen control unit 43. In addition, the screen display unit 44 displays a list of names and contact information of users who use the vehicle 6 displayed on the map. The list is a list in which the locations of the vehicles 6 are sorted in order from near to far from the location of the corresponding elevator system 10.

[0079] In this embodiment, the controller of the control center can refer to the map and list displayed in step S306 to contact the vehicle user at the site near the corresponding elevator system 10. As a result, the vehicle 6 can be dispatched to the trapped site due to the power outage earlier, and the dispatched vehicle 6 can be powered to the charging and power supply device 3. In this way, the charging of the charging and power supply device 3 of the elevator system 10 can be performed more quickly from the vehicle 6 (electric vehicle), and the elevator 1 can be operated more quickly.

[0080] As described above, in the second embodiment, also in the elevator system 10 including the charging and power supply device 3, it is possible to quickly rescue passengers from being trapped in the elevator 1 due to a power outage.

[0081] In the second embodiment, the position information of the vehicle 6 in use is obtained in step S303, but in addition, the power status of the vehicle 6 in use may be obtained. Furthermore, in step S305, the dispatch priority of the dispatchable vehicles 6 is determined based on the power status of the vehicle 6 in use in addition to the position condition of the vehicle 6 in use, thereby enabling more accurate rescue operations to be performed.

[0082] However, the first and second embodiments are structures for the purpose of searching for a vehicle owned by a responsible business office responsible for maintenance and inspection of the elevator system 10, and dispatching a vehicle 6 owned (managed) by the responsible business office to the trapped site earlier. However, the present invention is not limited to this, and for example, it is also possible to request a management company that manages a building where the elevator system 10 is installed to dispatch a vehicle (electric vehicle) 6 that can supply electricity. The following describes the processing process performed before contacting the management company when a power outage occurs in the elevator system 10 having the charging and power supply device 3.

[0083] 3. Third Embodiment (Example with Different Vehicle Search Method)

[0084] An elevator monitoring method according to a third embodiment of the present invention will be described. Figure 5 1 is a flowchart showing a vehicle search method according to a third embodiment of the present invention. In the third embodiment, in an elevator system 10 having a charging and power supply device 3, a vehicle search process performed in the event of a power outage causing a person to be trapped in an elevator 1 is an example different from that of the first and second embodiments. Figure 2 The processing procedure executed after the determination of "yes" in step S104 is different from that in the first embodiment and the second embodiment. In addition, the functional structure of the elevator monitoring system 100 is the same as that in the first embodiment, so it is omitted from the illustration and the repeated description is omitted.

[0085] First, the vehicle search unit 46 confirms that a entrapment due to a power outage has occurred in the elevator system 10 including the charging and power supply device 3 based on the determination result of the situation determination unit 45 in step S104 (step S401 ).

[0086] Next, the vehicle search unit 46 extracts information about the management company that manages the elevator system 10 where the power outage occurred from the management company information database (DB) 424 of the elevator information storage unit 42. The information about the management company includes the name of the management company and the person in charge of the management company, the contact information of the management company, and information about whether it is possible to go to the site by electric vehicle.

[0087] Next, the vehicle search unit 46 determines whether the person in charge of the management company can go to the power outage site by the electric car 6 based on the information extracted in step S402 (step S403). If the determination in step S403 is "no", that is, if it is determined that the electric car 6 cannot go from the management company to the power outage site, the process ends. Figure 5 process.

[0088] On the other hand, if the judgment in step S403 is "yes", that is, if it is judged that the electric car 6 can go from the management company, the process proceeds to step S404. In step S404, the screen control unit 43 controls the screen display unit 44 according to the judgment result of step S403 to display that the person in charge of the management company can go to the site where the power outage occurred by the electric car 6. Specifically, the management company that manages the corresponding elevator system 10 and the name of the person in charge of the management company, the contact information of the management company, and the content of the entrustment to the management company are displayed. Specifically, the entrustment content includes the content of the main purpose of going to the site where the corresponding elevator system 10 is installed by the electric car and connecting the electric car 6 to the charging and power supply device 3.

[0089] In the third embodiment, the controller can confirm the content displayed on the screen display unit 44 in step S404, and the controller can contact the corresponding management company to request the electric car 6 to go. In this way, in the third embodiment, in the elevator system 10 having the charging and power supply device 3, when a person is trapped due to a power outage, the controller can quickly request the management company to allow the electric car 6 to go.

[0090] As described above, according to the present invention, in the elevator system 10 having the charging and power supply device 3 capable of charging the electric car 6 and supplying power to the elevator 1, even when the power of the charging and power supply device 3 is exhausted, the electric car 6 can be quickly moved to the site. In addition, according to the present invention, the control center can grasp the status of vehicles that can move in the management company and the responsible business office, so the controller can quickly decide on the response to the elevator 1 that is trapped due to the power outage.

[0091] The above-mentioned embodiments are described in detail for the purpose of explaining the present invention in an easy-to-understand manner, and are not limited to having all the structures described. For example, a part of the structure of the embodiment can be replaced with another structure, and another structure can be added to the structure of the embodiment. In addition, with respect to a part of the structure of the embodiment, another structure can be added, deleted, or replaced.
