Description

The present invention relates to, for example, a remote monitoring system for elevators.

For elevators, contractors and managers make maintenance contracts with maintenance companies, and maintenance companies inspect elevators and take measures in the event of a failure according to the contract information. In the United States and Europe, it is common to set detailed conditions such as response time for response in the event of a failure.

Further, a technique of installing a monitoring device capable of monitoring the operation of an elevator in a monitoring center and connecting to the monitoring center via a public line network to monitor the elevator is also generally known.
For example, Patent Document 1 states, "When a request for transmission of monitoring information from an information terminal owned by a customer is received, the monitoring data memory is stored only when the contract type of the customer is stored as a second contract in the customer information database. The monitoring information of the customer's elevator stored in the above is delivered to the customer's information terminal. "

Further, the technique disclosed in Patent Document 2 is known as a technique for supporting the planning of a maintenance service and operating a maintenance business by inputting actual data of an elevator to be maintained. This Patent Document 2 includes a maintenance business including "a maintenance service planning support system and a maintenance business plan planning support system that supports the planning of a maintenance business plan by having the maintenance business simulator calculate an evaluation index multiple times." "Support system" is described.

Japanese Unexamined Patent Publication No. 2007-112614 Japanese Unexamined Patent Publication No. 2004-323162

In the technique described in Patent Document 1, the monitoring device determines whether or not the information can be provided to the customer according to the contract information, and the monitoring center exceeds the level at which the abnormality in the abnormality occurrence information requires the dispatch of maintenance personnel. If it is determined, the maintenance staff will be instructed to dispatch. However, the contractor may not know exactly the maintenance level of the elevator. For this reason, it may be assumed that the maintenance staff should be dispatched even though the level of the maintenance staff is not abnormal. In this case, the response to the abnormality that occurred in the elevator may be delayed.

Further, the support system described in Patent Document 2 proposes parts replacement or elevator renewal according to the operating status of the elevator, and is used to instruct maintenance personnel to dispatch when an elevator failure occurs. It does not propose a review of the standard maintenance level.

Here, the monitoring device provided for the elevator detects an abnormal state generated in the elevator. Elevator abnormal conditions that can be detected by the monitoring device include a confinement failure in which the user is trapped in the car, a failure in which the user is not confined but the elevator cannot be used, and a transient failure in which the elevator can continue to operate. There is a failure etc. In addition, the state of the elevator, which is not currently out of order but may lead to a failure in the future, may be detected as an abnormal state of the elevator.

The monitoring device that detects these abnormalities notifies the monitoring center of the occurrence of the abnormal state. The monitoring center instructs the offices, etc. near the elevator where the abnormal condition has occurred to dispatch maintenance personnel, and the instructed maintenance personnel are dispatched to the site. However, if the elevator can be operated continuously, it is not always necessary to immediately dispatch the maintenance staff, and the work of the maintenance staff will increase. On the other hand, even if the abnormality is accompanied by the stop of the elevator, the maintenance staff does not respond to the abnormality not set in the contract information, so that the elevator does not operate for a long time. In general, many contractors want contracts that reduce downtime. However, the contractor did not know what kind of contract could shorten the elevator downtime, and could not properly change the existing contract information.

The present invention has been made in view of such a situation, and an object of the present invention is, for example, to enable a contractor of a remote monitoring system for an elevator to appropriately review contract information.

The remote monitoring system according to the present invention includes an elevator monitoring device that monitors the operation of an elevator, an elevator monitoring system that remotely monitors the operation of a plurality of elevators through the elevator monitoring device, and a contract for setting elevator contract information in the elevator monitoring system. It is equipped with an information setting device.
When the elevator monitoring device detects an abnormality in the operation of the elevator based on the operation information of the elevator input from the elevator control device that controls the operation of the elevator, the abnormality according to the type of abnormality that occurs in the elevator according to the contract information. It has an elevator monitoring unit that notifies the elevator monitoring system of the issue.
The elevator monitoring system receives the abnormal alarm notified from the elevator monitoring device, outputs the abnormal alarm to the contract information setting device, and records the contract information set by the contract information setting device. It has an information recording unit.
The contract information setting device includes the contract information set when the abnormal alarm is output from the alarm receiver, the information about the abnormal alarm notified according to the contract information, and the contract information recommended by the elevator monitoring system. And the information about the abnormality notification notified according to the recommended contract information is output in a comparable manner at a predetermined timing.

According to the present invention, for example, the contractor of the remote monitoring system for an elevator can review the contract information by confirming the contract information and the information related to the abnormality alarm that are comparablely output to the contract information setting device. ..

<Elevator monitoring device>
Here, a detailed internal configuration example of the elevator monitoring device 14 will be described.
The elevator monitoring device 14 includes an elevator monitoring unit 21, an abnormality information storage unit 23, a contract information storage unit 24, a monitoring center communication unit 25, and an intercom control unit 26. The elevator monitoring unit 21 includes a notification necessity determination unit 22.

The elevator monitoring unit 21 (an example of the elevator monitoring unit) monitors the operation of the elevator 11 with reference to the operation information of the elevator 11 output from the elevator control device 10. Then, when the elevator monitoring unit 21 detects an abnormality in the operation of the elevator 11 based on the operation information, the elevator monitoring system 30 is notified of an abnormality report according to the type of abnormality that occurs in the elevator 11 according to the contract information. do. For example, when the elevator monitoring unit 21 detects an abnormality in the elevator 11 such as confinement of the user in the car 12 from the operation information, the elevator monitoring unit 21 notifies the notification receiving unit 32 of the elevator monitoring system 30 of the abnormality notification. do.

Whether or not an abnormal notification is required is determined by the notification necessity determination unit 22. Based on the contract information read from the contract information storage unit 24, the alarm necessity determination unit 22 determines whether or not to issue an abnormal alarm to the alarm reception unit 32 of the elevator monitoring system 30. This contract information defines different reporting permission levels depending on the type of anomaly. Then, the report necessity determination unit 22 determines the necessity of the abnormality report according to the abnormality type of the abnormality detected from the operation information, and the elevator monitoring system 30 determines the abnormality report of the abnormality type determined to be the report required. Notify to. Here, the notification necessity determination unit 22 determines that the notification is required when the level of the abnormality type of the abnormality detected by the elevator monitoring unit 21 is equal to or higher than the notification permission level specified in the contract information. However, even if the level of the abnormality type of abnormality detected by the elevator monitoring unit 21 is lower than the predetermined notification permission level, the notification necessity determination unit 22 sets the abnormality type of abnormality in the individual notification item. If it is done and it is within the response time, it is judged that a notification is required.

The abnormality information storage unit 23 stores all the abnormalities of the elevator 11 detected by the elevator monitoring unit 21 as abnormality information indicating the abnormality of the elevator 11, regardless of whether or not the abnormality is reported.
The contract information storage unit 24 acquires and stores the contract information set in the elevator 11 to be monitored by the elevator monitoring unit 21 from the contract information recording device 34 of the elevator monitoring system 30.

The monitoring center communication unit 25 communicates with the elevator monitoring system 30 via the communication device 15. When the monitoring center communication unit 25 receives the acquisition request from the elevator monitoring system 30, it reads out the abnormality information stored in the abnormality information storage unit 23 and transmits it to the elevator monitoring system 30. Further, the monitoring center communication unit 25 can communicate with the intercom control unit 26. Further, the monitoring center communication unit 25 can store the contract information of the elevator 11 received from the elevator monitoring system 30 via the communication device 15 in the contract information storage unit 24.

The intercom control unit 26 notifies the abnormality information reading device 35 that the intercom 13 and the calling device 33 are connected to each other so that a call can be made. Upon receiving the notification from the intercom control unit 26, the abnormality information reading device 35 writes the abnormality information in the abnormality information recording device 36.

<Elevator monitoring system>
Next, a detailed internal configuration example of the elevator monitoring system 30 will be described.
The elevator monitoring system 30 can remotely monitor the operation of a plurality of elevators 11 through the elevator monitoring device 14. The elevator monitoring system 30 includes an elevator monitoring device communication unit 31, an alarm receiving unit 32, a communication device 33, a contract information recording device 34, an abnormality information reading device 35, and an abnormality information recording device 36.

The elevator monitoring device communication unit 31 communicates with the elevator monitoring device 14 by connecting to the communication device 15 provided in the building 2 via a wide area communication line.
The alarm receiving unit 32 receives the abnormal alarm notified from the elevator monitoring device 14 via the elevator monitoring device communication unit 31, and outputs the abnormal alarm to the contract information setting device 4. The contract information setting device 4 can display that an abnormality has been issued. Further, when the alarm receiving unit 32 receives the abnormal alarm, the instruction unit (not shown) of the elevator monitoring system 30 gives an instruction to the maintenance staff of the sales base closest to the elevator 11 to the site.

The calling device 33 (an example of a monitoring calling device) is connected to the intercom 13 of the car 12 and is used in the elevator monitoring system 30. The operator can make a call with the user in the car 12 by using the call device 33.

The contract information recording device 34 (an example of the contract information recording unit) records the contract information set by the contract information setting device 4 and the contract information updated by the contract information setting device 4. The contract information includes, for example, an abnormal type of abnormality in which an abnormality is reported to the elevator monitoring system 30, a time when a maintenance worker can be dispatched, and the like. A detailed configuration example of the contract information recorded in the contract information recording device 34 is shown in FIG. 3 to be described later.

The abnormality information reading device 35 (an example of the abnormality information reading unit) writes the abnormality information read from the abnormality information storage unit 23 in the elevator monitoring device 14 to the abnormality information recording device 36 at a predetermined timing. The predetermined timing is, for example, the first timing when the alarm receiving unit 32 receives the abnormal alarm, the second timing when the intercom 13 and the communication device 33 are connected to each other so that the call can be made, or the time when the current time reads the abnormal information. It is one of the third timings, which is the time for reading the abnormal information specified as. The second timing is specifically when the intercom control unit 26 connects to the communication device 33 provided in the elevator monitoring system 30 and starts a call between the intercom 13 and the communication device 33. The third timing is, for example, once a day when the designated time is reached.

The abnormality information recording device 36 (an example of the abnormality information recording unit) records the abnormality information read from the abnormality information storage unit 23 by the abnormality information reading device 35 and the abnormality report notified from the elevator monitoring unit 21.

<Contract information setting device>
The contract information setting device 4 is an example of an information processing device such as a PC (Personal Computer) or a smartphone, and is connected to the elevator monitoring system 30 through a communication line such as the Internet. The contract information setting device 4 includes a comparison output unit 41 and a contract information setting unit 42.

The comparison output unit 41 includes contract information set when an abnormal alarm is output from the alarm receiving unit 32, information on the abnormal alarm notified according to the contract information, and a contract recommended by the elevator monitoring system 30. The information and the information regarding the abnormal notification notified according to the recommended contract information are output in a comparable manner at a predetermined timing. At this time, the contract information setting device 4 outputs the abnormality information read from the abnormality information recording device 36 and the contract information read from the contract information recording device 34. Further, as the information regarding the abnormal alarm that is output in a comparable manner by the comparative output unit 41, there are the total non-operating time of the elevator 11 in a predetermined period and the content of the abnormal alarm (see FIG. 7 to be described later). Therefore, the contractor can confirm the content of the contract information comparatively displayed on the contract information setting device 4 and the content of the abnormality notification.

The contract information setting unit 42 sets the contract information of the elevator 11 input by the contractor in the elevator monitoring system 30. Further, the contract information setting unit 42 receives the contract information input according to the contract information recommended by the elevator monitoring system 30, and updates the contract information recorded in the contract information recording device 34. The updated contract information is sent to the contract information storage unit 24 of the elevator monitoring device 14, and the contract information stored in the contract information storage unit 24 is updated. Therefore, the elevator monitoring system 30 can inform the contractor of the content of the abnormality occurring in the elevator 11 and assist in the examination of the review of the contract information.

Next, the hardware configuration of the computer 40 constituting each device of the remote monitoring system 1 will be described.
FIG. 2 is a block diagram showing a hardware configuration example of the computer 40. The computer 40 is hardware used as a computer that can operate as an elevator monitoring device 14, an elevator monitoring system 30, and a contract information setting device 4.

The computer 40 includes a CPU (Central Processing Unit) 41, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, and a bus 44, which are connected to the bus 44, respectively. Further, the computer 40 includes a display device 45, an input device 46, a non-volatile storage 47, and a network interface 48.

The CPU 41 reads the program code of the software that realizes each function according to the present embodiment from the ROM 42, loads it into the RAM 43, and executes the program code. Variables and parameters generated during the arithmetic processing of the CPU 41 are temporarily written in the RAM 43, and these variables and parameters are appropriately read out by the CPU 41. However, an MPU (Micro Processing Unit) may be used instead of the CPU 41. Each function of the elevator monitoring device 14, the elevator monitoring system 30, and the contract information setting device 4 is realized by arithmetic processing of a program read from the ROM 42 by the CPU 41.

The display device 45 is, for example, a liquid crystal display monitor, and displays the result of processing performed by the computer 40 to the user. For example, a keyboard, a mouse, or the like is used as the input device 46, and the user can perform predetermined operation input and instruction. The contract information setting device 4 is provided with the display device 45 and the input device 46, but the elevator control device 14 and the elevator monitoring system 30 may not be provided with the display device 45 and the input device 46.

As the non-volatile storage 47, for example, HDD (Hard Disk Drive), SSD (Solid State Drive), flexible disk, optical disk, optical magnetic disk, CD-ROM, CD-R, magnetic tape, non-volatile memory and the like are used. Be done. In the non-volatile storage 47, in addition to the OS (Operating System) and various parameters, a program for operating the computer 40 is recorded. The ROM 42 and the non-volatile storage 47 permanently record programs, data, and the like necessary for the CPU 41 to operate, and are a computer-readable non-transient recording medium that stores the programs executed by the computer 40. It is used as an example. The abnormality information storage unit 23 and the contract information storage unit 24 of the elevator monitoring device 14, and the contract information recording device 34 and the abnormality information recording device 36 of the elevator monitoring system 30 record various information by the large-capacity non-volatile storage 47. It is possible.

For the network interface 48, for example, a NIC (Network Interface Card) or the like is used, and various data can be transmitted and received between devices via a LAN (Local Area Network) connected to a terminal of the NIC, a dedicated line, or the like. It is possible. The functions of the communication device 15 of the elevator monitoring device 14 and the elevator monitoring device communication unit 31 of the elevator monitoring system 30 are realized by the network interface 48.

Next, an example of contract information and abnormality information will be described with reference to FIGS. 3 and 4.
FIG. 3 is a diagram showing an example of contract information.

The contract information input from the contract information setting device 4 before the remote monitoring of the elevator 11 is started and recorded in the contract information recording device 34 is also stored in the contract information storage unit 24 in the elevator monitoring device 14. This contract information has a table structure in which major items, medium items, and contents are specified.

Major items include each item of issuance permission level, individual issuance item, and response time.
The notification permission level is an item for classifying the abnormal types of the elevator 11 into four levels according to the seriousness and designating the level at which the notification necessity determination unit 22 issues a report to the elevator monitoring system 30. be. Confinement is a failure in which the user is confined in the car, and in the present embodiment, confinement is classified as Level 4 as the most serious failure. Since confinement is a failure related to user safety, Level 4 content is set as permission in all contracts. Unable to start is a failure in which the elevator 11 does not move in the absence of a user, and a door abnormality is a failure in which the door does not open or the door does not close. The inability to start and the level of permission to issue a door abnormality are classified into level 3 as the second most serious failure after confinement.

The instantaneous power failure is a failure indicating that the elevator 11 has a momentary power failure due to a temporarily generated voltage abnormality. In the case of a momentary power failure, the alarm permission level is classified as level 2 because it has been restored at the present time. A speed abnormality is an abnormality in which the speed of the car is lower than usual, and a decrease in acceleration indicates an abnormality in which the acceleration of the car is lower than usual. At present, the speed abnormality and the acceleration decrease have been restored, and it is a minor failure that does not interfere with the operation of the elevator 11. However, since the speed abnormality and the acceleration decrease may be related to other abnormalities, the alarm permission level is classified into level 1.

The individual notification item is an item specified when the contractor individually wishes to issue a notification even if the notification permission level is an abnormal type belonging to a level classified as disapproval. Therefore, the contractor can operate the contract information setting device 4 to set the abnormality type included in the individual alarm item in advance.
The response time is an item that defines the time during which maintenance personnel can be dispatched for each day of the week when an abnormality in the elevator 11 is detected.

FIG. 4 is a diagram showing an example of abnormality information.
The abnormality information is composed of a table for accumulating the abnormality of the elevator 11 detected by the elevator monitoring unit 21 monitoring the operation of the elevator control device 10. This abnormality information is composed of each item of an abnormality detection time, an abnormality type, an alarm permission level, and an alarm necessity determination result, and is stored in the abnormality information storage unit 23.

The abnormality detection time is an item for storing the time when the elevator monitoring unit 21 detects an abnormality in the elevator 11.
The abnormality type is an item for storing the abnormality type of the abnormality detected by the elevator monitoring unit 21.
The alarm permission level is an item for storing the level corresponding to the abnormal type of the abnormality generated in the elevator 11. The level corresponds to the item in the contract information shown in FIG.
The report necessity determination result is an item for storing the report necessity determination result determined by the report necessity determination unit 22 with reference to the contract information storage unit 24. If it is necessary to issue a report, "○" is stored, and if it is not reported, "×" is stored.

Next, a process of determining whether or not an abnormal alarm is required by the alarm issue determination unit 22 will be described with reference to FIGS. 3 and 4.
Here, it is assumed that the contract information shown in FIG. 3 is recorded in the elevator 11, and the abnormality shown in FIG. 4 is detected. Therefore, the abnormality information shown in FIG. 4 will be described in order from the top with reference to the contract information shown in FIG.

The notification permission level to which "speed abnormality" belongs is "1", and the abnormality detection time is 16:00:16 on May 20, 2019 (Monday), so it is within the response time. Therefore, it is determined by the alarm necessity determination unit 22 that the alarm is not issued, and the elevator monitoring unit 21 does not issue an abnormal alarm.

The notification permission level to which "Unable to start" belongs is "3", but the abnormality detection time is 23:23:12 on June 19, 2019 (Wednesday), so it is out of the response time. Therefore, it is determined by the alarm necessity determination unit 22 that the alarm is not issued, and the elevator monitoring unit 21 does not issue an abnormal alarm.

The notification permission level to which "door abnormality" belongs is "3" permission, and the abnormality detection time is 11:02:12 on June 18, 2019 (Tuesday), so it is within the response time. Therefore, the report necessity determination unit 22 determines that the report is required, and the elevator monitoring unit 21 issues an abnormal report to the report reception unit 32 in the elevator monitoring system 30.

The notification permission level to which "instantaneous power failure" belongs is "2", and the abnormality detection time is 08:01:45 on Saturday, May 25, 2019, so it is out of the response time. Therefore, it is determined by the alarm necessity determination unit 22 that the alarm is not issued, and the elevator monitoring unit 21 does not issue an abnormal alarm.

The notification permission level to which "acceleration decrease" belongs is "1", but "acceleration decrease" is set as an individual notification item, and the abnormality detection time is 2019/5/15 (Wednesday) 16: Since it is 00:16, it is within the response time. Therefore, the report necessity determination unit 22 determines that the report is required, and the elevator monitoring unit 21 issues an abnormal report to the report reception unit 32 in the elevator monitoring system 30.

The notification permission level to which "confinement" belongs is "4" permission, but the abnormality detection time is 2019/4/23 (Tuesday) 04:08:27, so it is out of the response time. However, as mentioned above, confinement is an abnormality related to user safety and must be dealt with immediately. Therefore, the report necessity determination unit 22 determines that the report is required, and the elevator monitoring unit 21 issues an abnormal report to the report reception unit 32 in the elevator monitoring system 30.

Next, the details of the operation of the remote monitoring system 1 will be described with reference to FIGS. 5 and 6.
FIG. 5 is a flowchart showing an example of processing performed by the notification necessity determination unit 22 of the elevator monitoring unit 21.

First, the elevator monitoring unit 21 refers to the operation information of the elevator 11 from the elevator control device 10 and determines whether or not an abnormality in the elevator 11 has been detected (S1). When the abnormality of the elevator 11 is not detected (NO in S1), the elevator monitoring unit 21 repeats the process of step S1 again.

On the other hand, when the abnormality of the elevator 11 is detected (YES in S1), the notification necessity determination unit 22 confirms whether or not the detected abnormality is confinement (S2). When it is determined that the confinement is detected (YES in S2), the alarm necessity determination unit 22 issues an alarm to the monitoring center 3, that is, the elevator monitoring system 30 because the maintenance staff needs to take immediate action (S6). ..

On the other hand, when it is determined that an abnormality other than confinement has been detected (NO in S2), the notification necessity determination unit 22 refers to the notification permission level of the contract information recorded in the contract information storage unit 24. Then, the notification necessity determination unit 22 confirms whether the notification permission level to which the abnormality type of the abnormality detected by the elevator monitoring unit 21 belongs is permission in the contract information (S3).

When the issuance permission level is not permitted in the contract information (NO in S3), the issuance necessity determination unit 22 refers to the contract information recorded in the contract information storage unit 24, and is detected by the elevator monitoring unit 21. It is confirmed whether or not the abnormal type is an item set as an individual alarm item (S4). If this abnormality type is set as an individual alarm item (YES in S4), the process proceeds to step S5, and if it is not set as an individual alarm item (NO in S4), the elevator monitoring system 30 is notified. It is not performed, and the process proceeds to step S7.

When the issue permission level is permitted in the contract information (YES in S3), or when the abnormality type is set in the individual issue item (YES in S4), the issue necessity determination unit 22 uses the contract information. With reference to the contract information recorded in the storage unit 24, it is confirmed whether or not the time at the time of abnormality detection is within the response time of the contract information (S5). If the time at the time of abnormality detection is not within the response time of the contract information (NO in S5), the elevator monitoring system 30 is not notified and the process proceeds to step S7.

When the time at the time of abnormality detection is within the response time of the contract information (YES in S5), or when the abnormality type is confined (YES in S2), the notification necessity determination unit 22 determines that the notification is required. to decide. Then, the elevator monitoring unit 21 notifies the alarm receiving unit 32 in the elevator monitoring system 30 of an abnormal alarm (S6).

If the detected abnormality is not set in the individual notification item (NO in S4), if the time when the abnormality is detected is not within the response time in the contract information (NO in S5), or to the elevator monitoring system 30. After any of the cases (S6), the elevator monitoring unit 21 records the abnormality information in the abnormality information storage unit 23 (S7). As described above, the abnormality information is recorded regardless of the type of abnormality detected and the presence or absence of an alarm. After that, the notification necessity determination unit 22 ends this process.

FIG. 6 is a flowchart showing an example of a process in which the abnormality information reading device 35 reads out the abnormality information and the abnormality alarm.

First, the abnormality information reading device 35 determines whether or not the alarm receiving unit 32 has received the abnormal alarm from the elevator monitoring unit 21 (S11). If the alarm receiving unit 32 has not received an abnormal alarm (NO in S11), the intercom control unit 26 connects the intercom control unit 26 to the communication device 33 provided in the elevator monitoring system 30 to connect the intercom to the intercom. It is determined whether or not 13 and the communication device 33 are connected so as to be able to make a call (S12).

If the intercom 13 and the communication device 33 are not connected so as to be able to make a call (NO in S12), the abnormality information reading device 35 determines whether the current time is the abnormality information reading time (S13). If the current time is not the abnormality information reading time (NO in S13), the process returns to step S11.

When the alarm receiving unit 32 receives the abnormal alarm (YES in S11), when the intercom 13 and the calling device 33 are connected to each other so that the call can be made (YES in S12), or when the current time is the abnormal information reading time. (YES in S13), the abnormality information reading device 35 reads out the abnormality information recorded in the abnormality information storage unit 23. Then, the abnormality information reading device 35 records the read abnormality information in the abnormality information recording device 36 (S14).

After step S14, the contract information setting device 4 determines whether or not the contractor has confirmed the abnormality occurrence status of the elevator 11 in the contract information setting device 4 (S15). The process of step S15 is determined by, for example, whether or not the contractor operates the contract information setting device 4 and inputs the display instruction of the contract content confirmation screen 50 shown in FIG. 7, which will be described later. If the contractor has not confirmed the abnormality occurrence status (NO in S15), the process returns to step S11, and the abnormality information reading device 35 subsequently reads the abnormality information from the abnormality information storage unit 23 at a predetermined timing, and the abnormality information recording device 36 The operation of recording abnormal information is repeated.

On the other hand, if the contractor has confirmed the abnormality occurrence status (YES in S15), the comparison output unit 41 of the contract information setting device 4 reads out the abnormality information from the abnormality information recording device 36. Then, the comparison output unit 41 displays the abnormality report transmitted from the elevator monitoring system 30 and the abnormality information on the display device 45 (see FIG. 2) in a comparable manner (S16). At this time, the comparison output unit 41 of the contract information setting device 4 also displays the current contract information and the recommended contract information on the display device 45. After that, the abnormality information reading device 35 ends this process.

The contract information setting unit 42 of the contract information setting device 4 accepts changes in the contract information input by the contractor.

In the figure, for example, it is shown that the name of the building is "xxxxxx building" and the current contract content is "contract plan B".

The non-operating time display unit 52 includes a total non-operating time display area 60 for this month, an abnormality content display area 65, and a non-operating time display area 66 when the contract plan is changed.
In the total non-operation time display area 60 of this month, for example, in the case of contract plan B, the total non-operation time of the elevator 11 in this month (June 2019) is 173 minutes as the total non-operation time. Shown is a donut graph 61 with 100% total downtime this month. Further, the partial graph 62 superimposed on the donut graph 61 represents, for example, the expected non-operating time when the contract plan B is changed to the contract plan A.

In the abnormality content display area 65, the abnormality content of the abnormality detected this month is displayed. For example, in the abnormality content display area 65, it is shown that "unable to start failure" and "door abnormality failure" have been detected as the abnormality content. For example, when the contractor clicks on the "unable to start failure" or "abnormal door failure" indicated as the content of the abnormality, the time when the "unable to start failure" or "abnormal door failure" occurs, and the specific notification permission level. Content may be displayed. Further, in the abnormality content display area 65, the abnormality content for which the notification necessity determination unit 22 has determined that the notification necessity is not permitted may be displayed.
In the non-operating time display area 66 at the time of changing the contract plan, for example, it is shown that the assumed non-operating time when the contractor changes the contract plan B to the contract plan A changes from 173 minutes to 83 minutes.

The current contract content display unit 53 displays the contract content of the current contract in the elevator 11. As mentioned above, the current contract is "Contract Plan B". As for the contract contents of contract plan B, levels 3 and 4 are permitted as the notification permission level, 3 items are permitted as individual notification items, and the response time is from 9:00 to 18:00 from Monday to Friday and 9 on Saturday. It is stipulated that it is possible to respond from 13:00 to 13:00, but not on Sundays. In this way, in contract plan B, the number of items of individual notification items allowed is small and the response time is short, so if an abnormality that does not correspond to the individual notification item occurs or an abnormality occurs outside the response time. , It takes time to deal with abnormalities. As a result, the non-operating time tends to be long.

The recommended contract content display unit 54 displays the contract content of the contract recommended by the elevator monitoring system 30 to the contractor. For example, the recommended contract is "Contract Plan A". As for the contract contents of contract plan A, levels 2 to 4 are permitted as the notification permission level, 5 items are permitted as individual notification items, and the response time is 24 hours from Monday to Friday, 9 on Saturday and Sunday. It is stipulated that it is possible to respond from hour to 18:00. As described above, the contract plan A has a larger number of permitted individual alarm items and a longer response time than the contract plan B. Therefore, even if an abnormality should occur in the elevator 11, maintenance personnel will be dispatched immediately to respond to the abnormality, so contract plan A can reduce downtime compared to contract plan B. Will be.

In the remote monitoring system 1 according to the above-described embodiment, when an abnormality in the elevator 11 is detected, the contract information in which the abnormality type that can be notified of the abnormality and the time when the maintenance staff can be dispatched is recorded. Based on this, the notification necessity determination unit 22 determines whether or not an abnormal notification is necessary. The contract information stipulates the issuance permission level specified according to the type of abnormality and the permission or disapproval of abnormal notification for each issuance permission level. Therefore, the report necessity determination unit 22 issues an abnormality report determined to be a report required according to the abnormality type of the abnormality detected by the elevator 11 and the provisions of permission or disapproval of the abnormality report. Notify the elevator monitoring system 30. In the elevator monitoring system 30, since the dispatch instruction is given for an abnormality that requires the dispatch of the maintenance staff, the work load of the maintenance staff is reduced.

The contract information setting device 4 reads out the abnormality information recorded in the abnormality information recording device 36 and the abnormality alarm received by the alarm receiving unit 32, and the content of the detected abnormality information and the content of the abnormality alarm. And are displayed. At this time, the contract information setting device 4 displays the non-operating time of the elevator 11 caused by the current contract and the non-operating time of the elevator 11 predicted by the contract recommended by the elevator monitoring system 32 to the contractor in a comparable manner. do. At this time, the contract information setting device 4 also displays the contract information of the current contract and the contract information of the contract recommended to the contractor in a comparable manner. Therefore, the elevator monitoring system 30 can propose to the contractor a review of the maintenance level, which is a standard for the elevator monitoring system 30 to give a dispatch instruction to the maintenance staff when the elevator 11 fails. Is.

Further, the contractor can operate the contract information setting device 4 to set the contract information to issue an abnormality even if the abnormal type is specified as disapproval in the contract information. Therefore, the remote monitoring system 1 can easily set the contract information according to the contractor.
