Description

Elevator remote monitoring system

Technical field

[0001] The present invention relates to an elevator that performs automatic monitoring of elevators, escalators, and other elevators spread over a wide range including an area that is remote from the installation location of the monitoring center using a monitoring device provided in the monitoring center. It relates to a remote monitoring system.

Background art

[0002] For example, in a remote monitoring system that remotely monitors the operation state of a plurality of elevators such as elevators and escalators scattered in a wide area, each elevator such as an elevator or escalator to be monitored In addition, an operation monitoring terminal that constantly monitors the operating state of this elevator is incorporated.

[0003] Further, this operation monitoring terminal is installed in a monitoring center installed in a large city through a public communication line of a telephone company or, in some cases, a ground communication line such as a dedicated communication line owned by a company. Connected to a monitoring device.

[0004] An operation monitoring terminal incorporated in each elevator such as an elevator or an escalator constantly monitors the operation state of the elevator to be monitored. Then, when an abnormality including a failure occurs in the elevator to be monitored, this operation monitoring terminal transmits the abnormality occurrence information to the monitoring device of the monitoring center via the ground communication line.

[0005] When the monitoring device of the monitoring center receives the abnormality occurrence information from the operation monitoring terminal of the elevator such as an elevator or escalator, the display unit displays the abnormality occurrence information and the elevator in which the abnormality has occurred.

Display on the (Display Panel) to alert the monitoring center (operator)

[0006] When an abnormality is displayed on the display panel of the monitoring device, the operator checks the content of the abnormality. For example, in the case of a passenger confinement accident in an elevator car, Give appropriate instructions via the intercom. If necessary, the maintenance staff will be sent to the elevator installation site to rescue the passengers.

[0007] In this way, it is assembled in elevators, escalators and other elevators scattered in a wide area. When an abnormality occurs in the elevator that it monitors, the installed operation monitoring terminal sends information on the occurrence of the abnormality to the monitoring device of the monitoring center via the ground communication line, so that the elevator and escalator itself are operating normally. Confirm driving and ensure safety for elevator users.

[0008] Then, in the monitoring center installed in the big city, not only the metropolitan area where the monitoring center is installed, but also remote monitoring of each elevator installed in each city in neighboring prefectures and each building in the surrounding area. By doing so, maintenance costs for each elevator can be reduced. Disclosure of the invention

[0009] However, the following problems were also encountered in the above-described elevator remote monitoring system:

[0010] As described above, this elevator remote monitoring system includes not only each elevator that exists in the city where the monitoring center is installed, but also each elevator that exists in a wide area including cities in neighboring prefectures and surrounding areas. Watch! / Speak.

[0011] Therefore, an operation monitoring terminal incorporated in an elevator in a remote area that is remote from the position of the monitoring center generates an abnormality in the monitoring device of the monitoring center at a long distance via the ground communication line. Need to send information.

[0012] In such a wide area, for example, a large-scale or medium-scale disaster such as an earthquake, heavy snowfall, flood damage, etc. occurs, and the ground communication line between the monitoring center city and the remote area is destroyed or functioned. It is assumed that the network capacity is not limited or the line capacity is further limited.

[0013] In such a case, even if an abnormality occurs in each elevator in the remote area, the abnormality occurrence information is not transmitted to the monitoring center. In particular, when the remote area is affected by a disaster, there may be an emergency situation such as a passenger confinement accident in the elevator car, so measures must be taken in advance.

[0014] It should be noted that in the case of a communication line abnormality in a city where a monitoring center is installed, it is possible to allow maintenance personnel to make a patrol of each elevator in a relatively simple and short time. However, it is difficult for maintenance personnel to visit each elevator in a remote area in a short time.

[0015] The present invention has been made in view of such circumstances, and even if a large-scale disaster or a medium-scale disaster occurs, the remote monitoring for each elevator distributed over a wide area including a remote area. An object is to provide a remote monitoring system for an elevator capable of reliably performing visual observation.

[0016] In order to solve the above problems, the present invention is incorporated in a plurality of elevators provided in different places, and monitors a plurality of operation monitoring terminals that monitor the operation of the elevators. In the elevator remote monitoring system, which is connected to each terminal via a ground communication line and includes a monitoring device for remotely monitoring each elevator based on the elevator monitoring information received from each operation monitoring terminal. Among a plurality of elevators provided at different locations, operation monitoring terminals for a plurality of elevators provided in one or a plurality of remote areas that are remote from the position of the monitoring device. One or a plurality of base stations connected via a regional ground communication line, a satellite communication line connecting each base station and a monitoring device via a communication satellite, and each operation in a remote area A communication line switching unit that switches the transmission path of the monitoring information to the monitoring device to the satellite communication line via the ground communication line base station when the ground communication line between the monitoring terminal and the monitoring device is disconnected. Speak.

[0017] In the elevator remote monitoring system configured as described above, a ground communication line and satellite communication are provided between the operation monitoring terminal incorporated in each elevator in the remote area and the monitoring device of the monitoring center. There are two communication lines. In the normal state, the terrestrial communication line is used. When the terrestrial communication line is disconnected due to a disaster or the like, the satellite communication line is used.

[0018] Further, according to another invention, in the elevator remote monitoring system according to the invention described above, each operation monitoring terminal in the remote area makes a predetermined number of attempts to transmit monitoring information to the monitoring device using the ground communication line. And determine whether or not the ground communication line can be used based on the result. In this way, when the ground communication line is disconnected, the communication line is automatically switched from the ground communication line to the satellite communication line.

[0019] In the present invention, even if a large-scale disaster or a medium-scale disaster occurs, it is possible to reliably perform remote monitoring for each elevator distributed in a wide area including a remote area.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing a schematic configuration of a remote monitoring system for an elevator according to an embodiment of the present invention. In the following description, an elevator is exemplified as an elevator, but the present invention can also be applied to other elevators such as an escalator.

[0023] In each building 1 distributed in a wide range of different places, one or a plurality of elevators 2 as monitoring targets are provided. Each building 1 is provided with an operation monitoring terminal 3 that constantly monitors the operation state of each elevator 2 of one or a plurality of elevators 2 incorporated in the building 1. [0024] Among a plurality of buildings 1 distributed over a wide area, each operation monitoring terminal of each building 1 located in a remote area 5 that is remote from a monitoring center 4 provided in a relatively large city. 3 is connected to the communication section 7 in the monitoring center 4 through the terrestrial communication line 6, the terrestrial communication network 6a, and the terrestrial communication line 6 of the telephone company.

[0025] Of the plurality of buildings 1 distributed over a wide range, each operation monitoring terminal 3 of each building 1 located in the neighboring area 8 that is close to the monitoring center 4 is connected to the ground communication of the telephone company. It is connected to the communication section 7 in the monitoring center 4 via the line 9, the ground communication line network 9 a, and the ground communication line 9.

The maintenance staff 10 of the elevator maintenance management company that operates the monitoring center 4 has a portable terminal 11. This mobile terminal 11 has a function of exchanging various kinds of information including voice via the mobile phone line 12 with the communication unit 7 of the monitoring center 4, and the communication unit 7 of the monitoring center 4 via the Internet 13. Is accessible.

Furthermore, each operation monitoring terminal 3 of each building 1 located in the remote area 5 is connected to the base station 15 via the local ground communication line 14! A satellite communication line 17 passing through the communication satellite 16 is formed between the base station 15 and the communication unit 7 of the monitoring center 4 as necessary.

[0028] In addition to the communication unit 7 described above, a monitoring device 18 that is a computer operated by an operator is incorporated in the monitoring center 4.

[0029] An operation panel 19 that is operated by a user of the elevator 2 shown in FIG. This operation panel 19 has a car call button 20 for designating the destination floor of this car, an emergency button 21 for calling the operator of the monitoring center 4 when a confinement accident occurs, and a microphone 22 for notifying the operator of an abnormal state 22 A speaker 23 and the like are provided for the operator to output voice instructions.

FIG. 3 is a schematic configuration diagram of each operation monitoring terminal 3 of each building 1 located in the remote area 5. Abnormalities such as power outages, pit inundation, earthquake occurrence, etc. detected by each monitoring sensor 24, operation of the emergency button 21, and sound from the microphone 22 are input to the input interface 25. It is determined that there is an abnormality to be sent to 4. In this case, the abnormality information creation unit 27 creates “abnormality occurrence information” in which the elevator ID for identifying the elevator and the abnormality occurrence time are added to the abnormality type, and sends them to the transmission path determination unit 28. The transmission path determination unit 28 sends “abnormality occurrence information” to the ground communication unit 29 when the ground communication line 6 connected to itself is normal. The ground communication unit 29 transmits the “abnormality occurrence information” to the communication unit 7 of the monitoring center 4 via the ground communication line 6, the ground communication line network 6a, and the ground communication line 6.

On the other hand, the transmission path determining unit 28 sends “abnormality occurrence information” to the satellite communication unit 30 when the terrestrial communication line 6 connected to itself is not connected. The satellite communication unit 30 sends the “abnormality occurrence information” to the base station 15 via the regional ground communication line 14. Then, the base station 15 transmits this “abnormality occurrence information” to the communication unit 7 of the monitoring center 4 via the satellite communication line 17 passing through the communication satellite 6. Therefore, the transmission path determination unit 28 constitutes a communication line switching unit.

When a voice instruction from the operator to the trapped user is input to the ground communication unit 29 or the satellite communication unit 30, the voice output unit 31 outputs the voice instruction through the speaker 23.

[0034] In addition, in the case of an abnormality occurring due to a wide-area disaster such as an earthquake, a large number of "abnormality information" is input to the base station 15 from many elevators 2 in the remote area 5 in the same time zone. . A large number of “abnormality occurrence information” is incorporated into a communication packet and transmitted to the communication unit 7 of the monitoring center 4 via the satellite communication line 17.

FIG. 4 is a flowchart showing the monitoring process for the monitored elevator 2 of each operation monitoring terminal 3 of each building 1 located in the remote area 5.

[0036] When an abnormality is detected in the monitoring sensor 24, the emergency button 21, and the microphone 22 (step S1), the abnormality information creation unit 27 creates "abnormality occurrence information" (S2) and sets the number N of transmission attempts. Initial setting (N = 0) is performed (S3). Then, the transmission path determination unit 28 attempts to transmit “abnormality occurrence information” using the ground communication line 6 (S4). If there is a failure to transmit normally (S5), the number of transmission attempts N is updated (N = N + 1) (S6). If the number of transmission attempts after updating N has not reached a predetermined limit (for example, N = 5) (S7), for example, after a period of time such as At = 2 minutes (S8), return to S4, and again Then, the transmission of “abnormality information” using the terrestrial communication line 6 is tried. If the transmission is successful (S5), the process returns to S1.

[0037] In S7, when the number N of transmission attempts after the update reaches a predetermined limit number (N = 5), The upper communication line 6 is determined to be disconnected, and “abnormality occurrence information” is transmitted to the communication unit 7 of the monitoring center 4 via the base station 15 and the satellite communication line 17.

[0038] In this way, each operation monitoring terminal 3 of each building 1 located in the remote area 5 attempts transmission via the ground communication line 6, and whether or not the ground communication line 6 can be used a predetermined number of times. Is determined. When the terrestrial communication line 6 is disconnected, the communication line is automatically switched from the terrestrial communication line 6 to the satellite communication line 17.

[0039] It should be noted that each operation monitoring terminal 3 of each building 1 located in the neighboring area 8 that is close to the monitoring center 4 is monitored by each operation 1 of each building 1 located in the remote area 5 of FIG. In the terminal 3, the transmission path determination unit 28 and the satellite communication unit 30 are removed. That is, the “abnormality occurrence information” is transmitted unconditionally to the communication unit 7 of the monitoring center 4 via the terrestrial communication line 9, the terrestrial communication line network 9a, and the terrestrial communication line 9.

[0040] Each maintenance staff 10 visits the elevator 2 of each building 1 according to a predetermined schedule and performs maintenance inspection. Specifically, the maintenance staff 10 operates the mobile terminal 11 prior to the start of the maintenance inspection, and starts maintenance inspection information with the maintenance staff ID identifying itself and the unit ID identifying the inspection elevator 2. Is transmitted to the communication unit 7 of the monitoring center 4. Further, when the maintenance / inspection work is completed, the maintenance / inspection result is input to the portable terminal 11 and transmitted to the communication unit 7.

[0041] Note that the mobile terminal 11 possessed by the maintenance staff 10 is connected to the communication unit 7 of the monitoring center 4 via the normal mobile phone line 12, in addition to the mobile phone function for transmitting and receiving voice and information. It also has an Internet function for accessing the communication unit 7 of the monitoring center 4 via the network 13.

[0042] Therefore, when the mobile phone line 12 is difficult to communicate, such as when a wide-area disaster occurs, inspection start information and inspection end information may be transmitted to the communication unit 7 of the monitoring center 4 via the Internet 13. Is possible. It is also possible to receive instructions from the monitoring center 4 via the Internet 13.

FIG. 5 is a schematic configuration diagram of the communication unit 7 and the monitoring device 18 provided in the monitoring center 4. Within the communication unit 7, there are a satellite communication unit 32 that communicates with the base station 15 in the remote area 5 through the satellite communication line 17, and each operation monitoring terminal of each building 1 in the remote area 5 through the ground communication line 6. 3 Communicating with the remote land line communication unit 33 that communicates with 3 and the operation monitoring terminal 3 of each building 1 in the neighboring area 8 via the ground communication line 9 and maintenance personnel via the mobile phone line 12 while communicating with each operation monitoring terminal 3 1 0 Terrestrial landline communication unit 34 for communication with mobile terminals 11 of the local area, and communication unit for Internet (Web browser) 35 having sites where mobile terminals 1 1 of maintenance personnel 10 are accessed via the Internet 13 ! /

[0044] Further, in the communication unit 7, a receiving unit 36 for transferring various information including the "abnormality occurrence information" received by the communication units 32 to 35 to the control unit 39 of the monitoring device 18; A transmitting unit 38 is provided for transferring various information including a voice instruction designating a transmission destination instructed by the control unit 39 and an instruction to the maintenance staff 10 to the corresponding communication units 32-35.

[0045] Also, in this communication unit 7, information to be transmitted to each operation monitoring terminal 3 of each building 1 located in the remote area 5, the satellite communication unit 32, the remote land line communication unit 33, A route selection unit 37 is provided for selecting which communication unit to use.

[0046] For example, in the monitoring device 18 constituted by a computer, a diagram in which the positions of the respective elevators 2 to be monitored and the positions of the respective maintenance personnel 10 are described in addition to the control unit 39 that performs various types of information processing. Display unit 40 that displays the map 49 shown in Fig. 10, the monitoring unit 4's monitoring staff (operator) inputs instructions to each maintenance staff 10, and performs various operations. 41 The monitoring section 4's monitoring staff (operator) However, a telephone terminal 52 is provided for carrying out a voice call with the elevator 2 user who has been trapped.

[0047] In the storage unit 43 for storing various information, a customer information database 44, a monitoring target database 45, a maintenance staff database 46, a monitoring and maintenance inspection data memory 47, and a map database 48 are provided! /, The

In the customer information database 44, as shown in FIG. 6, customer information of each customer who has signed a maintenance contract for each elevator 2 with the maintenance management company that operates the monitoring center 4 is stored. That is, for each customer ID that identifies each customer, a customer name, address, telephone number, and unit ID that identifies each elevator 2 to be contracted are stored. For example, a customer with customer ID “K01” owns a total of four elevators E01, E02, E07, and E08.

In the monitoring target database 45, as shown in FIG. 7, information of each elevator 2 to be monitored in the monitoring device 18 is stored. That is, identify each elevator 2 For each unit ID, the location, building name (elevator unit), customer ID indicating the owner of this elevator 2, the ground communication lines 6 and 9 of the operation monitoring terminal 3 incorporated in each elevator 2 The line number 45a and the satellite line number 45b which is the telephone number of the satellite communication line 17 are stored.

[0050] As described above, when a plurality of elevators 2 are installed in one building 1, a plurality of elevators 2 are monitored by one operation monitoring terminal 3. There is one motion monitoring terminal 3 in one building.

[0051] In this embodiment, since the monitoring center 4 is installed in Tokyo, the Tokyo and Kanagawa prefectures are the neighboring areas 8, and the Yamanashi prefecture is the remote area 5. Therefore, the ground line number 45a and the satellite line number 45b are set in each operation monitoring terminal 3 of each elevator 2 of the unit IDs E07 to E010 in Yamanashi Prefecture, which is the remote area 5. However, only the terrestrial line number 45a is set in each operation monitoring terminal 3 of each elevator 2 of Unit IDs E01 to E06, El l and E12 in the neighboring area 8 Tokyo and Kanagawa Prefecture.

[0052] In the maintenance person database 46, as shown in FIG. 8, for each maintenance person ID that identifies each maintenance person 10, the name, telephone number (mobile phone number), whether or not the maintenance inspection work for the elevator 2 is in progress. The current status of the vehicle and the ID number of the corresponding elevator 2 when maintenance inspection is in progress are stored. Specifically, when maintenance inspection disclosure information is input from the mobile terminal 11 of the maintenance staff 10, the current status of the maintenance staff 10 is changed during the maintenance inspection, and the Unit ID of the corresponding elevator 2 is set. Furthermore, when maintenance inspection completion information (maintenance inspection result) is input, the current status of the corresponding maintenance staff 10 is changed during movement, and the Unit ID of the corresponding elevator 2 is cleared.

[0053] In the monitoring / maintenance inspection data memory 47, as shown in FIG. 9, the monitoring result 47a and the maintenance inspection result 47b are sequentially stored for each unit ID identifying each elevator 2, and the maintenance point The current state 47c of whether or not the inspection work is in progress is stored. The monitoring result 47a is abnormality occurrence information including the abnormality content and the occurrence time transmitted from the operation monitoring terminal 3 of the elevator 2 via the ground communication lines 6 and 9 or the satellite communication line 17.

[0054] Maintenance inspection result 47b is a result of the maintenance inspection periodically performed by the maintenance staff 10 on the elevator 2, the execution time, and the maintenance staff ID. This maintenance inspection result 47b is This is included in the maintenance inspection end information transmitted from the mobile terminal 11. Therefore, the maintenance inspection result of “no abnormality” is also stored.

[0055] A map is stored in the map database 48. When a position indicated by an address is specified, a map 49 is read and displayed on the display unit 40 as shown in FIG.

[0056] On the map 49 displayed and output on the display unit 40, a “△” mark and a unit ID are displayed at the position of the elevator 2 to be monitored. The “mouth” mark and the maintenance staff ID are displayed at the 0 position. The maintenance and inspection work for elevator 2 is completed, and a “○” mark and a maintenance person ID are displayed at the position of maintenance person 10 in an empty state (moving or out of work).

[0057] Furthermore, an "X" mark is displayed at the position of the elevator 2 to be monitored, where an abnormality such as a failure has occurred and the maintenance staff 10 needs to be rescued. In addition, a “*” mark and a maintenance staff ID are displayed at the current position of the maintenance staff 10 reported by the maintenance staff 10 out of the maintenance staff 10 in an empty state that is not under maintenance and inspection work.

A map 49 shown in FIG. 10 is always displayed on the display unit 40 while the monitoring device 18 of the monitoring center 4 is in operation.

[0059] Then, the control unit 39 of the monitoring device 18 of the monitoring center 4 performs monitoring control for each elevator 2 according to the flowcharts shown in Figs.

[0060] When maintenance inspection start information is input from the mobile terminal 11 owned by the maintenance staff 10 via the nearby landline communication section 34 or the Internet communication section 35 (step Q1), the maintenance staff database 45 Set the current status of the maintenance personnel during maintenance inspection, and set the status 47c of the corresponding elevator 2 in the monitoring / maintenance inspection data memory 47 during operation. Furthermore, the “mouth” mark during maintenance inspection and maintenance are located at the position adjacent to the “△” mark of the corresponding elevator 2 displayed on the map 49 shown in FIG. The employee ID is displayed (Q2).

[0061] When maintenance inspection completion information (maintenance inspection results) is input from the mobile terminal 11 owned by the maintenance staff 10 via the nearby landline communication unit 34 or the Internet communication unit 35 (Q3), maintenance is performed. Set the current status of the maintenance personnel in the operator database 46 while moving and monitor The entered maintenance inspection result 47b is additionally written in the maintenance inspection result area of the corresponding elevator 2 in the inspection data memory 47. At the same time, clear the work in state 47c. Furthermore, the “mouth” mark that is displayed at the position adjacent to the “△” mark of the elevator 2 displayed on the map 49 shown in FIG. And clear the maintenance personnel ID (Q4).

[0062] When abnormality occurrence information is input from the operation monitoring terminal 3 of the elevator 2 (Q5), it is checked in which communication unit 32-35 in the communication unit 7 this abnormality occurrence information has been received. Only when it is received by the satellite communication unit 32 (Q6), the satellite link flag is set to 1 (Q7). Then, this abnormality occurrence information is additionally written as a monitoring result 47a in the monitoring result area of the corresponding elevator in the monitoring / maintenance inspection data memory 47 (Q8). Then, whether or not the abnormality in the abnormality occurrence information needs to be handled by a monitoring person (operator) such as a confinement accident is automatically determined based on a predetermined abnormality type (Q9).

[0063] When the operator needs to respond, the route selection unit 37 checks the state of the satellite line flag. If the satellite line flag is set to 1 (Q10), it is determined that the terrestrial communication line 6 leading to the remote area 5 is disconnected at the present time. Then, a voice response is made to the operation monitoring terminal 3 that is the source of the abnormality occurrence information in the remote area 5 through the path of the satellite communication unit 32, the satellite communication line 17, the base station 15, and the regional ground communication line 14 (Q11).

The operation monitoring terminal 3 outputs the received operator's voice from the spinning force 23 in the car of the elevator 2. Therefore, the user of the elevator 2 confined in the force can talk with the operator of the monitoring center 4 via the interphone composed of the microphone 22 and the speaker 23. The operator can give appropriate instructions to the user. When the conversation ends, the satellite communication line 17 is disconnected and the satellite line flag is cleared to 0 (Q12).

[0065] In Q10, if the satellite line flag is not set to 1, it is determined that the ground communication line 6 leading to the remote area 5 is normal and the ground communication line 9 leading to the neighboring area 8 is also normal. Then, a voice response is made to the operation monitoring terminal 3 that is the transmission source of the abnormality occurrence information in the remote area 5 or the neighboring area 8 via the ground communication lines 6 and 9 (Q13). The operation monitoring terminal 3 receives The operator's voice is output from the speaker 23 in the elevator 2 car.

[0066] Further, if the abnormality in the received abnormality occurrence information is below a predetermined level requiring dispatch of maintenance personnel 10 (Q14), the process returns to Q1.

[0067] When the level of abnormality exceeds the level that requires the dispatch of maintenance personnel 9, the current display section 40 km is displayed “△” of the elevator 2 displayed on the map 49 shown in FIG. The mark is changed to an “X” mark that indicates that an error has occurred and the maintenance staff 10 needs to be rescued. Furthermore, maintenance personnel 10 who are not currently in the maintenance inspection work set to move to the current status in the maintenance personnel database 46 are extracted (Q15).

[0068] Then, the extracted mobile terminal 11 of each maintenance person 10 is automatically called. When the maintenance person 10 responds, the operator inquires the maintenance person 10 about the current position (Q 16). When the address of the current position is informed from the maintenance staff 10 (Q17), when the operator inputs the address from the input section 41, it is displayed on the current display section 40 in the map database 48! On the map 49, the current position of the maintenance staff 10 who is not currently working is indicated by “*” and the maintenance staff ID is displayed (Q18).

[0069] The operator of the monitoring center 4 detects the error indicated by “*”, which indicates that an abnormality has occurred in the map 49 shown in FIG. The maintenance staff 10 actually going to rescue is designated from the position of the base and the position of each maintenance staff 10 not working at the present time indicated by “X”.

[0070] Then, when the maintenance staff 10 designated by the operator is designated by the input unit 41 (Q19), it is displayed on the display unit 40! In the map 49 shown in FIG. 10, the elevator position indicated by “*” is displayed. Edit the map displaying only the maintenance staff position indicated by the “X” of the maintenance staff 10 selected as the maintenance staff 10 and rescue the designated maintenance staff 10 to the portable terminal 11 with the elevator 2 specified. Send along with work execution instructions (Q20).

[0071] Therefore, the selected maintenance person 10 displays the position of the rescue target elevator 2 marked "X" and the current position of the maintenance person 10 marked "*" on the display screen of his portable terminal 11. Referring to, go to rescue 2 for rescue.

In the remote monitoring system for elevators thus configured, for example, each elevator 2 of the building 1 in the remote area 5 far away from the monitoring center 4 installed in a large city. Between the operation monitoring terminal 3 incorporated in the communication device 7 and the communication unit 7 in the monitoring device 18 of the monitoring center 4, there are two communication lines: a ground communication line 6 and a satellite communication line 17 via the base station 15 and the communication satellite 15. Communication lines 6 and 17 are provided.

[0073] In the normal state, the ground communication line 6 is used. In addition, when the ground communication line 6 connecting the remote area 5 and the monitoring center 4 is disconnected due to a disaster or the like, the satellite communication line 17 is used.

[0074] Therefore, even if a large-scale disaster or a medium-scale disaster occurs and the ground communication line 6 between the monitoring center 4 and the remote area 5 is disconnected, the operation monitoring of each elevator 2 in the remote area 5 is performed. Information communication between the terminal 3 and the monitoring device 18 of the monitoring center 4 becomes possible.

[0075] As a result, remote monitoring of each elevator 2 distributed over a wide area including the remote area 5 and the neighboring area 8 can be reliably performed, and the safety of the users of each elevator 2 can be further improved.
