Description

The present invention relates to an elevator remote monitoring device and an elevator system.

For elevators, the manager (building company, etc.) makes a maintenance contract with the maintenance company, and the maintenance company inspects the elevator and responds in the event of a breakdown according to the contract details.
Depending on the country where the elevator is installed (US, Europe, etc.), conditions such as response time may be set in detail as a service level agreement for response in the event of a breakdown.
It is also common to install a remote monitoring device in an elevator and connect it to a monitoring center via a public network to monitor the elevator.

When the monitoring center monitors the elevator, the degree of monitoring depends on the contents of the maintenance contract between the manager and the maintenance company. For example, at night or on holidays, only emergency response may be provided, and minor troubles may be overtime and maintenance contracts may be made.
By making these maintenance contracts, it is possible to reduce the response by the operator at night or on holidays at the monitoring center, and it is possible to reduce the workload of the operator at night or on holidays when operating the monitoring center. can.

According to Patent Document 1, when an elevator equipped with a reporting device is monitored by a monitoring center, the reporting device of the elevator makes a call to the monitoring center immediately after detecting the occurrence of a confinement failure or by an intercom device in the car. Immediately after detecting the end, a technique for permitting a call with a monitoring center or the like is described only for a preset permission period.

Japanese Unexamined Patent Publication No. 2012-153506

One of the conditions for the abnormal condition of the elevator is a call request from the intercom in the elevator car. The elevator is equipped with an intercom for making calls inside and outside the car, and it is possible to make a call between the intercom in the car and the operator of the monitoring center. The intercom in the car has a call button, and the passenger presses this call button to make a call request to the outside. By making a call using this intercom, even if an accident occurs in which a passenger is trapped in the car, it is possible to take measures such as rescue.

Therefore, regardless of the content of the maintenance contract, the monitoring center usually waits for 24 hours to make a call using the intercom. Then, when the call button of the intercom is pressed, the monitoring center determines that it is in a high-level abnormal state and deals with the operation of the call button.

However, in actual elevator operation, if there is no abnormality in the elevator, the call button is often pressed by mistake or due to mischief. In this case, it is not necessary to dispatch maintenance personnel. Even if there is no situation, the dispatch instruction may be given. Further, even when the maintenance staff does not need to be dispatched, the operator of the monitoring center needs to confirm the cause of the press of the call button of the intercom when the call button of the intercom is pressed. That is, it is necessary to confirm the situation such as whether the operation of the call button of the intercom is wrong or mischievous, or whether it is due to the failure of the elevator, and it takes time to confirm these.
Therefore, in the past, even if the maintenance contract does not provide maintenance services at night or on holidays, the monitoring center must handle the operation of the call button of the intercom in case of an emergency, which is a burden on the monitoring center operator. There was a problem that it was big.

Here, for example, by applying the technique described in Patent Document 1 to limit the call, it is possible to reduce the number of reports to the monitoring center using the intercom in the car, and reduce the workload of the operator of the monitoring center. be able to.
However, in order to ensure the safety of passengers in the car, it is necessary to wait so that calls can be made at all times without any restrictions, and to be able to make reliable contact in the event of an abnormality. .. Therefore, it is difficult to restrict the call of the intercom in the car under uniform conditions. It is also preferable to limit the time for responding to the intercom in the car according to the contents of the maintenance contract from the viewpoint of reducing the workload of the operator of the monitoring center, but from the viewpoint of ensuring the safety of passengers in the car, it is more than necessary. There was a problem that call restrictions could not be made. Therefore, in the prior art, the workload of the operator of the monitoring center has not been sufficiently reduced.

According to the present invention, when there is a call request from inside the elevator car, it is possible to reliably deal with an abnormality while reducing the load on the operator by limiting the necessity of connecting to the monitoring center according to the contract contents. It is an object of the present invention to provide an elevator remote monitoring device and an elevator system that can be used.

In order to solve the above problems, for example, the configuration described in the claims is adopted.
The present application includes a plurality of means for solving the above problems. For example, in an elevator remote monitoring device, a contract information storage unit for storing maintenance contract information regarding elevator maintenance service hours and an elevator when the car in intercom Kobotan is pressed, with reference to the contract information stored in the contract information storage unit, for monitoring the call control processing unit for controlling the call with the operator of the monitoring center-car intercom, the elevator It is equipped with an elevator monitoring and processing unit.
Then, when the call button for the intercom in the car is pressed within the maintenance service time of the maintenance contract information stored in the contract information storage unit, the call control processing unit makes a call between the intercom in the car and the operator of the monitoring center. Connection processing is performed.
Furthermore, when the intercom call button in the car is pressed outside the maintenance service hours of the maintenance contract information stored in the contract information storage unit, the elevator monitoring processing unit determines that the elevator is not operating normally. , Performs connection processing for a call between the intercom in the car and the operator of the monitoring center.

According to the present invention, when the intercom call button in the car is operated outside the maintenance service hours of the elevator, it is connected so that it can talk only when normal operation is not possible, and it is possible to deal with an abnormality. It is possible to reduce the response time of the operator of the monitoring center and reduce unnecessary dispatch instructions to the maintenance staff while ensuring the operation.
Issues, configurations and effects other than those described above will be clarified by the description of the following embodiments.

Hereinafter, an example of an embodiment of the present invention (hereinafter, referred to as “this example”) will be described in detail with reference to the accompanying drawings.

[1. System-wide configuration]
FIG. 1 shows the overall configuration of the elevator system of this example.
The elevator system of this example includes an elevator car 11 installed in the building 10. The car 11 is controlled to travel (elevate) by the elevator control device 14. Note that in FIG. 1, a mechanism for running the car 11 such as a hoist is omitted.

An intercom 12 is arranged in the car 11. The intercom 12 includes an intercom call button 12a, an intercom speaker 12b, and an intercom microphone 12c. The passenger 13 in the car 11 can talk to the outside such as the monitoring center 20 described later by using the intercom speaker 12b and the intercom microphone 12c by pressing the intercom call button 12a.

Further, a remote monitoring device (elevator remote monitoring device) 15 is installed in the building 10 to monitor the elevator installed in the building 10.
The remote monitoring device 15 is connected to the elevator control device 14 and the intercom 12. The remote monitoring device 15 includes an elevator communication processing unit 15a, a monitoring center communication processing unit 15b, an elevator monitoring processing unit 15c, a call control processing unit 15d, a contract information storage unit 15e, and a voice guidance storage unit 15f.

The elevator communication processing unit 15a communicates with the elevator control device 14.
The monitoring center communication processing unit 15b communicates with a partner (here, the monitoring center 20) connected to the public network 2 via the communication device 1.
The elevator monitoring processing unit 15c monitors the state of the elevator car 11 and the elevator control device 14 by using the data acquired from the elevator control device 14 by the elevator communication processing unit 15a.
When an abnormality occurs in either the elevator car 11 or the elevator control device 14, the monitoring center communication processing unit 15b communicates with the monitoring center 20 side via the communication device 1 and the public network 2.

When the intercom call button 12a in the car 11 is pressed, the call control processing unit 15d performs a process of connecting the intercom speaker 12b and the intercom microphone 12c to the call device 22 or the automatic answering device 23 in the monitoring center 20. .. By performing this connection process, the passenger 13 can receive a call with the operator 26 in the monitoring center 20 or an automatic response by the automatic response device 23 by the intercom speaker 12b and the intercom microphone 12c. The call control processing unit 15d selects the connection destination (connection for operator call or connection for automatic answering), for example, when connecting to the communication device 3 described later on the monitoring center 20 side in the public network 2. This can be achieved by transmitting a control signal indicating whether or not the connection is made. Alternatively, the connection destination may be selected by changing the telephone number of the connection destination to which the call control processing unit 15d connects or changing the address (IP address or the like) of the connection destination.
Further, even when the elevator monitoring processing unit 15c detects an abnormality such as when the passenger 13 is trapped in the elevator car 2, the call control processing unit 15d connects the intercom 12 to the monitoring center 20 side. Perform the processing.

The contract information storage unit 15e stores maintenance contract information concluded with a business operator (a business operator operating the monitoring center 20) that performs maintenance and inspection work for the elevator installed in the building 10. For the maintenance contract information stored in the contract information storage unit 15e, the monitoring center communication processing unit 15b communicates with the monitoring center 20 side via the communication device 1 and the public network 2, and the contract condition recording unit of the monitoring center 20. This is the information obtained from 24.

The voice guidance storage unit 15f stores voice guidance information output from the intercom speaker 12b when the intercom 12 by the call control processing unit 15d is connected to the monitoring center 20. For example, voice guidance information for outputting voice such as "Please wait for a while because it is connected to the monitoring center" is saved. A specific example of the voice guidance saved by the voice guidance storage unit 15f will be described later when the process when the intercom call button is pressed is explained.

The connection process with the intercom 12 by the call control processing unit 15d is performed according to the maintenance contract information stored in the contract information storage unit 15e. Specifically, whether the current day or time zone is the day or time zone within the maintenance contract indicated by the maintenance contract information, or the day or time zone outside the maintenance contract indicated by the maintenance contract information. The connection processing state by the call control processing unit 15d changes accordingly. In the following description, the day or time zone within the maintenance contract indicated by the maintenance contract information is referred to as within the service time, and the day or time zone not within the maintenance contract is referred to as outside service time.
As the connection processing by the call control processing unit 15d here, first, the voice guidance output from the intercom speaker 12b changes depending on whether or not the current day or time zone is within the service time indicated in the maintenance contract information. do.
Further, in the connection processing (whether or not the connection to the monitoring center 20 is possible, etc.) by the call control processing unit 15d after the voice guidance is output, whether or not the current day or time zone is within the service time indicated in the maintenance contract information. It changes depending on the situation. However, processing such as voice guidance output processing and connection availability also changes depending on factors other than whether or not it is within the service time. Specific processing that changes according to these maintenance contracts and the like will be described later in the flowchart of FIG.

The monitoring center 20 is composed of a monitoring server 21 composed of a computer and peripheral devices connected to the monitoring server 21, and is installed in a facility operated by a business operator performing maintenance and inspection work. .. FIG. 1 shows only elevators installed in one building 10 as elevators connected to the monitoring center 20, but the monitoring center 20 actually executes a process of collectively monitoring a plurality of elevators.

The monitoring center 20 includes a communication device 3, a monitoring server 21, a communication device 22, and an automatic answering device 23. The communication device 3 is connected to the public network 2 and executes communication between the monitoring server 21 and the remote monitoring device 15 of the elevator.
The monitoring server 21 includes a contract condition recording unit 24 and a server communication processing unit 25.
The server communication processing unit 25 communicates with the communication device 1 connected to the remote monitoring device 15 on the building 10 side via the communication device 3 and the public network 2.
In the call device 22, the connection process for the operator 26 in the monitoring center 20 to make a call with the passenger 13 via the intercom 12 in the car 11 is performed based on the connection request from the remote monitoring device 15. .. That is, when the connection request for a call from the remote monitoring device 15 is transmitted to the call device 22 based on the operation on the intercom 12, the call device 22 performs a process of calling the operator 26. Then, when the operator 26 responds to the call processing, the microphone and the speaker in the communication device 22 get on via the server communication processing unit 25, the communication device 3, the public network 2, and the communication device 1. It is connected to the intercom speaker 12b and the intercom microphone 12c in the car 11.

When the intercom 12 is connected from the remote monitoring device 15 on the building 10 side, the automatic answering device 23 automatically answers by voice instead of the call from the calling device 22 by the operator 26 when a predetermined condition is satisfied. That is, when the condition for automatic response is satisfied at the time of connection request from the remote monitoring device 15, the automatic response device 23 passes through the server communication processing unit 25, the communication device 3, the public network 2, and the communication device 1. It is connected to the intercom speaker 12b and the intercom microphone 12c in the car 11. When the condition for satisfying the automatic response condition here is satisfied, there is also a case where there is a request (transmission of the corresponding control signal) for instructing the connection to the automatic response device 23 at the time of the connection request from the remote monitoring device 15. When the automatic answering device 23 responds to the connection request from the remote monitoring device 15, the process of calling the operator 26 in the calling device 22 is not performed. However, the operator 26 may be notified by display or the like on the monitoring center 20 side that the automatic response device 23 is in the process of automatic response.
For example, the automatic response device 23 automatically responds to the passenger 13 by voice output using the intercom speaker 12b in the car 11, and receives the answer from the passenger 13 by button operation or voice input by the intercom microphone 12c. , Judge the situation in the car 11. As one of the voice responses output from the intercom speaker 12b at the time of automatic response by the automatic answering device 23, "If you want to talk with the operator, please press the XX button." Is output, and the calling device 22 Allows the transition to a call with the operator 26. In addition to performing automatic response by voice prepared in advance, the automatic response device 23 uses artificial intelligence (AI) or the like to change the content of the voice text that automatically responds according to the situation at that time. You may let it.

The contract condition recording unit 24 records information on maintenance contract conditions for all elevators monitored by the monitoring center 20. The information regarding the elevator maintenance contract conditions recorded in the contract condition recording unit 24 is information regarding the maintenance contract conditions that the elevator manager (building company, etc.) concludes with the elevator maintenance company. The information regarding the maintenance contract conditions recorded in the contract condition recording unit 24 is acquired from, for example, the contract information 31 held in the maintenance system server 30 prepared by the business operator performing the maintenance and inspection work.

[2. Hardware configuration example]
The remote monitoring device 15 shown in FIG. 1 and the monitoring server 21 of the monitoring center 20 can be configured by, for example, the computer shown in FIG.
The computer C shown in FIG. 2 includes a CPU (Central Processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (Random Access Memory) C3 connected to the bus C8, respectively. Further, the computer C includes a non-volatile storage C4, a network interface C5, an input device C6, and a display device C7.

The CPU C1 is an arithmetic processing unit that reads a program code of software that realizes a function performed by the remote monitoring device 15 (or the monitoring server 21) from the ROM C2 and executes it.
Variables, parameters, etc. generated during the arithmetic processing are temporarily written in the RAM C3. Execution of the control process by the remote monitoring device 15 (or the monitoring server 21) is realized mainly by the CPU C1 executing the program code.

For the input device C6, for example, a keyboard, a mouse, or the like is used. In the case of the remote monitoring device 15, the operator uses the input device C6 to perform an input operation during maintenance and inspection of the elevator. In the case of the monitoring server 21, the monitoring worker (operator) performs monitoring work such as instructions using the input device C6.
The display device C7 is, for example, a liquid crystal display monitor, and the result of the control process executed by the computer by the display device C7 is displayed. In the case of the monitoring server 21, the monitoring worker (operator) monitors the state of the elevator by displaying on the display device C7.

For the non-volatile storage C4, for example, a large-capacity information storage medium such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) is used. A program for performing remote control processing is recorded in the non-volatile storage C4. The contract information storage unit 15e and the voice guidance storage unit 15f described above are composed of the non-volatile storage C4.
For the network interface C5, for example, a NIC (Network Interface Card) or the like is used. The network interface C5 transmits and receives various information to and from the outside via a LAN (Local Area Network), a dedicated line, and the like.

When the remote monitoring device 15 and the monitoring server 21 are configured by a computer, one or both of the input device C6 and the display device C7 shown in FIG. 2 may not be provided.
Further, the remote monitoring device 15 and the monitoring server 21 are configured by the computer shown in FIG. 2 as an example, and may be configured by other arithmetic processing devices other than the computer. For example, a part or all of the functions performed by the remote monitoring device 15 and the monitoring server 21 may be realized by hardware such as FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

[3. Example of maintenance contract information]
FIG. 3 shows an example of elevator maintenance contract information stored in the contract information storage unit 15e of the remote monitoring device 15.
In this example, as shown in FIG. 3, the maintenance service time is set by the contract for each day of the week from Monday to Sunday. For example, Monday, Tuesday, Wednesday, Thursday, and Friday are contracted for maintenance service hours from 9:00 am (9:00) to 6:00 pm (18:00). On Saturday, the contract is made from 9:00 am (9:00) to 1:00 pm (13:00) as maintenance service hours for maintenance management. On Sundays, contracts are made outside of maintenance service hours, where maintenance is not performed throughout the day.

Further, in the example of FIG. 3, a specific date and time other than the day of the week is set as an individual setting and is set as a time when maintenance management is not performed. Specifically, December 31, 2018 and January 1, 2019 are individually set as non-maintenance service hours without maintenance management throughout the day.
Further, in the example of FIG. 3, it is contracted to allow the report after the maintenance service time (overtime response report). If it is contracted to allow overtime response reports, the monitoring center 20 will make a report at that time in the event of an elevator failure such as the confinement of passengers in the car 11 even outside the above-mentioned maintenance management hours. It is designed to correspond to.

The maintenance contract information stored in the contract information storage unit 15e of the remote monitoring device 15 is, for example, from the monitoring center 20 to the remote monitoring device 15 when the contract conditions recorded in the contract condition recording unit 24 of the monitoring center 20 are updated. Will be delivered to. Alternatively, the remote monitoring device 15 may periodically access the monitoring center 20, and the remote monitoring device 15 may read out the contract condition recording unit 24 to check whether the contract conditions have been updated. Alternatively, the contract conditions recorded in the contract condition recording unit 24 of the monitoring center 20 may be transferred to the remote monitoring device 15 by an operation by a maintenance worker.

[4. Processing when the intercom call button is pressed]
FIG. 4 is a flowchart showing an example of processing by the remote monitoring device 15 when the intercom call button 12a in the car 11 is pressed by the passenger 13.
First, the call control processing unit 15d determines whether or not the intercom call button 12a has been pressed (step S11). Here, when the intercom call button 12a is not pressed (No in step S11), the call control processing unit 15d repeats the determination of whether or not the intercom call button 12a in step S11 has been pressed.

Then, when it is determined in step S11 that there is an operation of pressing the intercom call button 12a (Yes in step S11), the call control processing unit 15d determines that the operation of pressing the intercom call button 12a is performed for a predetermined time (Yes). Specified time T1) It is determined whether or not it is continuous (step S12). The specified time T1 is a relatively long time such as 10 seconds or 20 seconds. In this step S12, it is determined that there is an operation in which the specified time T1 is continuously pressed, in order to eliminate a report caused by being pressed due to mischief or an erroneous operation.

Then, when it is determined in step S12 that the call is not continuously pressed for the specified time T1 (No in step S12), the call control processing unit 15d may or may not be pressed by the intercom call button 12a in step S11. Return to the judgment of.
If it is determined in step S12 that there is an operation to be pressed beyond the specified time T1 (Yes in step S12), the call control processing unit 15d stores the current day of the week and time in the contract information storage unit 15e. It is determined whether or not it is within the maintenance service time indicated by the maintenance contract information (step S13).

If it is determined in step S13 that it is within the maintenance service time (Yes in step S13), the call control processing unit 15d transmits the normal guidance voice at the time of calling stored in the voice guidance storage unit 15f to the intercom speaker 12b. Output from (step S14). As the normal guidance voice here, for example, "Please wait for a while because it is connected to the monitoring center" is output. Then, the call control processing unit 15d executes the connection of the monitoring center 20 to the call device 22 in parallel with the output of the normal guidance voice (step S15).

When the connection to the call device 22 of the monitoring center 20 is executed, the call device 22 performs a process of calling the operator 26, and when the call device 22 of the monitoring center 20 operates the operator 26 to answer the call, A voice call is made between the passenger 13 in the car 11 and the operator 26.

If it is determined in step S13 that the maintenance service time is out (No in step S13), then the elevator monitoring processing unit 15c of the remote monitoring device 15 determines whether or not the elevator can be normally operated. Is determined (step S16). If it is determined in step S16 that the elevator is not in a state in which normal operation is possible (No in step S16), the call control processing unit 15d shifts to step S14 and calls when the elevator is called, as in the case of processing within the contract time. The normal guidance voice of is output from the intercom speaker 12b. Further, the process proceeds to step S15 to execute the connection of the monitoring center 20 to the communication device 22.

On the other hand, if it is determined in step S16 that the elevator is in a state where it can be normally operated (Yes in step S16), the elevator monitoring processing unit 15c of the remote monitoring device 15 has some abnormality in the same elevator within the past 30 minutes. It is determined whether or not there was a problem (step S17). In this step S17, the determination time is set to the past 30 minutes or less as an example, and the determination time may be arbitrarily changed according to the type of abnormality or the like. In addition to the abnormality that the elevator cannot be operated, the abnormality here includes a transient abnormality that the elevator automatically recovers. The abnormality here includes not only an abnormality due to an obvious failure such that the elevator cannot be operated, but also a case where some abnormal state occurs even if it cannot be regarded as a failure.

When it is determined in step S17 that there is an abnormality (Yes in step S17), the call control processing unit 15d outputs voice guidance from the intercom speaker 12b to inform the passenger 13 that the connection is made with the automatic answering device 23 (step S17). S18). Here, the intercom speaker 12b outputs voice guidance such as "The elevator is operating normally, so it will be connected to the automatic response device. Please wait." Based on the data saved by the voice guidance storage unit 15f. ..

Then, the call control processing unit 15d executes the connection of the monitoring center 20 to the automatic answering device 23 (step S19). When there is a call from the call control processing unit 15d, the automatic answering device 23 automatically responds with a voice indicating a situation in which the elevator can be operated.
Here, for example, "A temporary abnormality occurred earlier, but now it has returned to normal operation and the elevator can be used normally. If you want to talk to the operator, press the XX button." Make a response.

If the passenger 13 presses a specific button (the above-mentioned XX button) on the operation panel after being guided by the automatic response voice during the automatic response by the automatic response device 23, the call control processing unit 15d will perform the call control processing unit 15d. , Executes the connection of the monitoring center 20 to the communication device 22, and shifts to the communication with the operator 26.

If it is determined in step S17 that there is no abnormality within the predetermined time in the past (No in step S17), the call control processing unit 15d has the maintenance service time in the maintenance contract stored in the contract information storage unit 15e. It is determined whether or not there is an outside report permission setting (step S20). Here, if there is no setting for permission to report outside the maintenance service hours (No in step S20), the call control processing unit 15d intercoms the unanswerable guidance voice based on the data stored in the voice guidance storage unit 15f. Output from the speaker 12b (step S21).
Here, the intercom speaker 12b outputs voice guidance such as "The elevator cannot be connected to the monitoring center because it is operating normally and it is out of the corresponding time."

If it is determined in step S20 that the notification permission is set outside the maintenance service time (Yes in step S20), the call control processing unit 15d is based on the data stored in the voice guidance storage unit 15f. , The guidance voice for performing the overtime response is output from the intercom speaker 12b (step S22).
Here, the intercom speaker 12b is a voice such as "The elevator is operating normally, so it is outside the monitoring center reception hours. In an emergency, keep pressing the call button until it is connected to the monitoring center." Output guidance.

After that, the call control processing unit 15d determines whether or not the time when the intercom call button 12a is pressed exceeds the predetermined time T2 (step S23). The specified time T2 is set to, for example, 30 seconds. If it is determined in step S23 that the time when the intercom call button 12a is pressed exceeds the specified time T2 (Yes in step S23), the call control processing unit 15d shifts to step S14 and gives normal guidance at the time of calling. The sound is output from the intercom speaker 12b. Further, the process proceeds to step S15 to execute the connection of the monitoring center 20 to the communication device 22.

Further, in step S23, when it is determined that the time during which the intercom call button 12a is pressed does not exceed the specified time T2, or when it is determined that the intercom call button 12a is not pressed (No in step S23), call control The processing unit 15d returns to the determination in step S11.

FIG. 5 is a flowchart showing a processing example when there is a connection request from the remote monitoring device 15 at the monitoring center 20.
First, the server communication processing unit 25 of the monitoring center 20 determines whether or not there is data transmitted from the remote monitoring device 15 (step S31). If it is determined in step S31 that there is no received data transmitted from the remote monitoring device 15 (No in step S31), the server communication processing unit 25 performs step S31 until there is data transmitted from the remote monitoring device 15. Repeat the judgment of.

Then, when it is determined in step S31 that there is transmission data from the remote monitoring device 15, the server communication processing unit 25 determines whether or not the received data is a call request (step S32). Here, when it is determined that the received data is a call request (Yes in step S32), the server communication processing unit 25 connects the call device 22 to the remote monitoring device 15 based on the call request and answers the call. After the operation of the operator 26, a call with the operator is executed through the communication device 22 (step S33).

If it is determined in step S32 that the received data is not a call request (No in step S32), the server communication processing unit 25 determines whether or not the received data is a connection request of the automatic answering device (No). Step S34). If it is determined in step S34 that the received data is a connection request for the automatic response device (Yes in step S34), the server communication processing unit 25 remotely monitors the automatic response device 23 based on the connection request for the automatic response device. It connects to the device 15 and executes an automatic response by the automatic response device 23 (step S35).

Further, when it is determined in step S34 that the received data is not a connection request for the automatic response device (No in step S34), the server communication processing unit 25 performs normal data reply processing based on the received data request. (Step S36). The normal data response processing in step S36 is the exchange of data necessary for the monitoring processing by the monitoring server 21. When the maintenance contract information stored by the contract information storage unit 15e of the remote monitoring device 15 is acquired at the request of the remote monitoring device 15, the maintenance contract information is transmitted by the response processing of the normal data.

As described above, according to the elevator system of this example, the remote monitoring device 15 installed on the building 10 side has the contract information storage unit 15e, and is based on the maintenance contract stored in the contract information storage unit 15e. , It becomes possible to appropriately respond to a call request by the intercom 12 in the car 11. That is, since the monitoring center 20 does not have to respond to the call request outside the maintenance service time, the response time of the operator 26 of the monitoring center 20 can be reduced, and unnecessary dispatch instructions of the maintenance staff are also reduced. can do. Therefore, the load on the operator 26 and the maintenance staff of the monitoring center 20 can be significantly reduced.

In particular, in the case of this example, the voice guidance is changed in the remote monitoring device 15 installed in the building 10 depending on the presence or absence of an abnormality and whether it is out of the contract range, so that when a call request of low importance is made, the monitoring center 20 is used. It is possible to reduce the burden on the operator 26 by eliminating the need to make a call request.

Here, in the case of this example, even if the maintenance contract information indicates that the maintenance service time is out, when the elevator monitoring processing unit 15c detects an abnormal case in which normal operation cannot be performed, a call to the monitoring center 20 is made. Since the request is made, it is possible to ensure the safety in monitoring the elevator.

Further, when a call is requested from the elevator, even if the maintenance service time is out and normal operation is possible at that time, if an abnormality has occurred within a certain period of time in the past, the monitoring center 20 automatically responds. The device 23 will handle the problem, and the device 23 will be able to handle the problem appropriately. That is, when an abnormality has occurred within a certain period of time in the past and a call request is made by the intercom 12, the operator 26 does not respond and automatically responds even if the abnormal state is recovered. Appropriate guidance to passenger 13 can be provided at. Further, at the time of automatic response, the operator 26 can respond as needed, so that safety can be ensured.

[5. Modification example]
The present invention is not limited to the above-described embodiment, and includes various modifications.
For example, in the above-described embodiment, when the remote monitoring device 15 outputs voice guidance or the automatic answering device 23 responds, the communication device 22 of the monitoring center 20 can be operated by operating a button such as the intercom call button 12a. To connect to the operator 26. On the other hand, in each situation, the voice of the passenger 13 acquired by the intercom microphone 12c is voice-recognized, and based on the voice recognition result, the communication device 22 of the monitoring center 20 connects to the operator 26. May be good.

Further, the example of the voice output as the voice guidance described in the above-described embodiment is also an example, and the voice may be different from the above-mentioned example. For example, if there is permission to set an out-of-contract report in step S22 of FIG. 4, the overtime response guidance voice will be "Out of response time. The process of connecting to the monitoring center may incur charges. You may output such as "Do you want to connect to the center?" To inform you that billing will be done.

Further, in the above-described embodiment, the remote monitoring device 15 stores the voice guidance, but the monitoring center 20 stores a part or all of the voice guidance, and the automatic response device 23 processes the voice guidance. , The corresponding voice guidance may be output.
Further, when the automatic response device 23 automatically responds, the monitoring center 20 acquires information such as the state of the elevator at the time of calling from the remote monitoring device 15, and determines the acquired current and past states. You may make it respond automatically by voice. In this case, the automatic response device 23 can appropriately generate a voice that automatically responds by utilizing artificial intelligence (AI).

In addition, the above-described embodiment examples have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations. Further, in the configuration diagram of FIG. 1 and the like, only the control lines and information lines considered to be necessary for explanation are shown, and not all the control lines and information lines are necessarily shown in the product. In practice, it can be considered that almost all configurations are interconnected. Further, in the flowcharts shown in FIGS. 4 and 5, the execution order of some processing steps is changed or some processing steps are executed at the same time within a range that does not affect the processing results of the embodiment. You may do it.

Further, the configuration described in the above-described embodiment may be realized by software by the processor interpreting and executing a program that realizes each function. Information such as a program that realizes each function can be stored in a memory, a hard disk, a recording device such as an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, or an optical disk.
