Description

[Technical Field]

[0001] The present invention relates to a building facility information providing system and a building facility information providing method. [Background technology]

[0002] When a malfunction occurs in an elevator or building equipment, there is a service that allows building managers to check the malfunction detection status on the maintenance company's monitoring system and the dispatch status of maintenance personnel.

[0003] However, this service is aimed at building managers who have signed a maintenance contract, so if, for example, an elevator passenger drops their key in the gap between the elevator and the landing, the only way to find out whether a maintenance worker has been dispatched is to contact the operator at the elevator monitoring center or inquire with the building manager.

[0004] Since building managers are not necessarily near passengers and are difficult to contact, they will have to call an operator at the monitoring center.

[0005] However, the number of operators is limited, making it difficult for passengers to understand the situation in a timely manner. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2021-179753 Summary of the Invention [Problem to be solved by the invention]

[0007] Patent Document 1 discloses an in-building information reference system that includes a data reference request processing unit that accepts data reference requests when a customer wishes to refer to the operating status of building equipment of other customers in the same building, notifies the request to the customer operation terminal of the request-recipient customer user, and processes the procedure for the request-recipient customer user to approve or reject, and an application status management DB that integrates the data of the request-recipient and requesting customers and stores and manages the application procedure status so that the requesting customer user can refer to the request-recipient customer's information when the request-recipient customer user approves the data reference request.

[0008] In order for building facility users, building managers, and maintenance staff to understand each other's status, an operator at the monitoring center must act as an intermediary, and when multiple requests from users occur simultaneously, there are not enough operators available to respond.

[0009] Furthermore, services that allow building managers to check the status of fault detection for building equipment and the dispatch status of maintenance personnel are information that can be viewed by the building manager, who is the maintenance contract holder for the building equipment, and it is not desirable to make all of the viewable information available to building users. [Means for solving the problem]

[0010] The above problem is solved by an information provision system for building facilities that provides maintenance information for building facilities received from a remote monitoring device that monitors the building facilities, and that includes a reception unit that receives requests for maintenance information from a user terminal, access authority information that is information for determining whether or not maintenance information can be provided to the user terminal, and an accessibility determination unit that uses the access authority information to determine whether or not the maintenance information requested by the reception unit can be provided. [Effects of the Invention]

[0011] The present invention makes it easier for users of building facilities to know the building facilities' maintenance plans and the response status of maintenance personnel. [Brief explanation of the drawings]

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing for explaining the embodiments, the same components are given the same names and reference numerals as much as possible, and repeated explanations thereof will be omitted.

[0014] The present invention is not limited to the following examples, and includes various modifications and equivalent configurations within the spirit and scope of the appended claims. For example, the above examples have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations.

[0015] Furthermore, the processing units and processing modules described in the embodiments may be realized in part or in whole in hardware, for example by designing them as integrated circuits, or may be realized in software by having a processor interpret and execute a program that realizes each function.

[0016] The information explained in the embodiment may be a table, a database (DB), or data stored in the main memory.

[0017] Below, an elevator will be described as an example of building equipment. [Example]

[0018] FIG. 1 is a diagram showing an example of the system configuration of an elevator information providing system according to an embodiment of the present invention.

[0019] In this embodiment, an elevator information providing system will be described as an example, but the present invention can also be applied to building facilities other than elevators, such as air conditioning equipment and security systems that are remotely monitored.

[0020] Passengers using elevator 3 can use user terminal 42 to call operator telephone 22 at monitoring center 1 via public line network 6 to notify the operator of a malfunction or to request the collection of any objects that have fallen into the gaps in the elevator.

[0021] The operator uses the operator terminal 10 to access the remote monitoring device 9, check the status of the elevator, and then, via the remote monitoring network 7, request a response to the passenger's request to the maintenance worker terminal 5 held by a maintenance worker near the requested elevator.

[0022] The operator registers maintenance information such as the elevator operation status, malfunction status, and maintenance personnel allocation information in the remote monitoring device 9 from the operator terminal 10.

[0023] The registered elevator maintenance information is sent to the information providing device 2 and can be accessed via the Internet from a building manager terminal 4 (smartphone, etc.) held by the building manager. Here, the building manager refers to the building owner, the condominium management association, or a building manager who has been requested by the building owner or the condominium management association to manage the building. Building management authority may be given to multiple people.

[0024] Since the access authority from the building manager's terminal 4 to the maintenance information device is registered in advance in the information providing device 2, it is possible to access the information providing device 2 and refer to the maintenance information and the like.

[0025] However, since the access rights from the user terminal 42 (smartphone, etc.) of the elevator user are not registered in the information providing device, it is necessary to confirm that the user is an elevator user so that only information relevant to that user can be provided.

[0026] In order to solve such a problem, the configurations of the remote monitoring device 9 and the information providing device 2 will be mainly explained.

[0027] The monitoring center 1 is provided with a remote monitoring device 9 connected to the elevator 3 via a remote monitoring network 7 in order to remotely monitor the elevator 3 .

[0028] The remote monitoring device 9 is realized by a computer and includes a CPU (Central Processing Unit) 11, a main memory device 12, an external memory device 13 such as an HDD (Hard Disk Drive) or SSD (Solid State Drive), an input / output unit 14, and the like.

[0029] In this embodiment, an example will be described in which the system is configured using a computer such as a PC (Personal Computer), but it may also be configured using a cloud system in which computer resources are virtualized.

[0030] The main memory device 12 includes an abnormality identification unit 15 that receives an elevator abnormality alert, and an update unit 16 that updates the contents of the elevator maintenance table.

[0031] The abnormality identification unit 15, update unit 16, liquid crystal panel control unit 17, etc. are realized as software modules, and are executed by the CPU 11 by referring to information such as tables stored in the external storage device 13.

[0032] The external storage device 13 stores an elevator maintenance table 18 that stores elevator maintenance information, disclosure range information 19 that indicates the extent to which the elevator maintenance table may be disclosed to the building manager and users, and building information 20 that stores the name and location of the building in which the elevator is installed, the contents of the maintenance contract, etc.

[0033] An operator terminal 10 is connected to the remote monitoring device 9, and an operator can input and output data to and from the remote monitoring device 9 via an input / output unit 14.

[0034] An information providing device 2 is connected to the remote monitoring device 9. In this embodiment, the information providing device 2 is directly connected to the remote monitoring device 9, but it may be connected via a network as long as security is ensured.

[0035] In this embodiment, the information providing device 2 is configured as hardware independent of the remote monitoring device 9. This configuration ensures high security for the remote monitoring device 9, which monitors the safe operation of the elevator.

[0036] By logically configuring the information providing device 2 within the remote monitoring device 9 and configuring it as a logically independent system, it is possible to reduce the cost of configuring the system while maintaining the security of the remote monitoring device 9, and it is also possible to efficiently copy or share information provided to users to the information providing device in operation.

[0037] The information providing device 2 is also realized by a computer and includes a CPU 30 , a main memory device 31 , an external memory device 32 , and an input / output unit 33 .

[0038] The main memory device 31 is equipped with a reception unit 34 that receives a request from a building manager or a user to view maintenance information related to building facilities, a building facility identification unit 35 that identifies the building facility for which the viewing request has been received, an access permission determination unit 36 ​​that uses access permission information 39 stored in the external memory device 32 to determine whether or not the maintenance information related to the maintenance information viewing request received by the reception unit 34 can be accessed (whether or not it can be provided), and an access permission update unit 37 that updates the access permission information 39 using maintenance information 38 stored in the external memory device 32.

[0039] The external storage device 32 stores maintenance information 38, which is part of the elevator maintenance table, and access authority information 39 for the maintenance information 38 set for each user. The access authority for each user can be set by the building manager and is updated by the access authority update unit 37.

[0040] The input / output unit 33 receives information on the elevator maintenance table 18 that can be made public to the building manager or users and disclosure range information 19 from the remote monitoring device 9. In addition, the input / output unit 33 provides maintenance information 38 to the building manager or users via the Internet 8 based on the determination result of the accessibility determination unit 36.

[0041] The maintenance information 38 receives the contents of the updated elevator maintenance table 18 from the remote monitoring device 9 at predetermined time intervals, but it is not necessary to receive all the updated contents, and it is sufficient to receive the information specified in the disclosure range information 19.

[0042] By preventing information that is not disclosed to the user or building manager from being sent to the information providing device 2, not only can the processing load for updating information be reduced, but also the risk of information leakage can be reduced.

[0043] Access permission information 39 is information in which access permission information for users is added to disclosure range information 19. Information about the disclosure range determined by the administrator changes infrequently, so it does not need to be updated in real time. On the other hand, information about the disclosure range for users needs to be updated by the access permission update unit and provided to users in a timely manner, so both disclosure range information 19 and access permission information 39 need to be updated in real time.

[0044] FIG. 2 is an example of a flowchart showing the processing of the elevator information providing system according to the embodiment of the present invention.

[0045] Requests from users (passengers) are received by telephone 22 from user terminal 42 via public line network 6 to an operator at monitoring center 1. An abnormality alert for elevator 3 is received from elevator 3 via the remote monitoring network to remote monitoring device 9 or from an elevator user (S1), and is registered in elevator maintenance table 18 (S2).

[0046] A request from a user is registered by an operator in the elevator maintenance table 18 using the operator terminal 10 (S1).

[0047] An operator registers maintenance information in the maintenance table (S2). For example, if on-site work is required, a maintenance person near the elevator is assigned and the information is registered in the elevator maintenance table 18. The elevator maintenance table 18 is updated by the update unit 16, whether by the operator, the maintenance person, the building manager, or the remote monitoring device. Of the information registered in the maintenance table, information that can be provided to the building manager based on the disclosure range information is output to the information providing device.

[0048] The reception unit 34 in the information providing device 2 receives an inquiry about maintenance information and identity verification information from the user (S3), and performs identity verification of the user (S4). If identity verification fails, the process ends. If identity verification is successful (S5), the access authority update unit determines whether or not to provide maintenance information (S6), and updates the access authority (S7).

[0049] When the information providing device 2 receives an inquiry for maintenance information from a user terminal 42 via the Internet, the accessibility determination unit determines whether access is permitted based on the access authority information 39 and provides the information to the user terminal 42 (S8).The method of providing the information here is not limited to the means such as granting access to the server or sending an email based on the access authority information.

[0050] Furthermore, when providing information, all accessible information may be displayed, or items of accessible information may be displayed and only the information selected by the user may be output.

[0051] When the remote monitoring device 9 receives input from the maintenance staff indicating that the request has been handled or that the abnormality has been handled, the update unit 16 registers the information in the elevator maintenance table 18, and if the registration process is included in the disclosure range information, the update unit 16 instructs the information providing device 2 to update the maintenance information of the information providing device 2.

[0052] The information providing device 2 updates the maintenance information in response to an instruction from the update unit 16. The access authority update unit 37 determines whether the maintenance information has been updated (S9), and if the public information has been updated and the request has been handled and the fault has been handled, the access right of the user is deleted (S10) and the process ends. If the request has not been handled and the fault has not been handled, the requested information continues to be provided within the information disclosure range (S8).

[0053] This process can prevent a user terminal that has been permitted access from accessing the information providing device for an unnecessarily long period of time.

[0054] To enable the user to confirm that the maintenance personnel have completed the request response or the fault response, the access authority may remain for a predetermined time after the information indicating the completion of the request response or the fault response is registered in the public information, or until it is detected that the information has been accessed a predetermined number of times.

[0055] For example, if a user drops a key in a gap in an elevator and requests its retrieval, access rights can be retained for about a week after the retrieval is completed, and the access rights can be left so that the user can access the key at least once after the retrieval is completed.This allows the user to confirm that the request has been completed and go to the building's management department to retrieve the key.

[0056] FIG. 3 is an example of a flowchart showing an abnormality detection process in the remote monitoring device 9 according to the embodiment of the present invention.

[0057] It is determined whether the abnormality identification unit 15 has identified an abnormality by issuing an elevator malfunction alert (S20) or whether a request has been received from a building user to the control center (S21).

[0058] In the case of a fault report, the remote monitoring device acquires the identifier of the report source and a fault signal code indicating the details of the fault (S22).

[0059] The obtained identifier is used to search the elevator maintenance table 18, and the elevator to be monitored in which the fault has occurred is identified (S23).

[0060] Furthermore, the faulty part corresponding to the fault code is identified from the elevator maintenance table (S24), and the update unit 16 updates the fault response information in the elevator maintenance table 18 (S26).

[0061] When a request is received from a building user at the control center, the operator identifies the building from which the request originated using keywords related to the location of the building, such as part of the address, part of the building name, or the company name, and the building and the request details are entered into the remote monitoring device 9 from the input screen of the operator terminal 10 (S25).

[0062] By the above processing, failure response information is registered in the elevator maintenance table whether the remote monitoring device receives an alert or the operator receives a request from the user by telephone or the like.

[0063] FIG. 4 is an example of a flowchart showing the process of identity verification in an embodiment of the present invention.

[0064] An elevator car may be equipped with a liquid crystal panel 41. The liquid crystal panel 41 usually displays information such as the floor registered as the destination floor and the current floor.

[0065] When a fault occurs in an elevator or a request is received from a user, the abnormality identification unit 15 in the remote monitoring device 9 identifies the elevator (S30). By referring to the building information 20, it is determined whether the identified elevator has an in-car LCD panel 41 (S31), and a command to display a two-dimensional barcode is output from the LCD panel control unit 17 to the elevator identified in S30 (S32).

[0066] In the case of an elevator with a liquid crystal panel inside the car, a two-dimensional barcode is displayed on the liquid crystal panel 41 (S32), and the user accesses the URL (Uniform Resource Locator) written on the two-dimensional barcode on the user terminal 42.

[0067] The reception unit 34 of the information providing device 2 determines whether the requester information has been entered from the URL (S33), and if it has been entered correctly, the two-dimensional barcode on the LCD panel 41 inside the car is deleted (S34), and the identity verification is successful (S39).

[0068] The requester information may be the building information or car number information of the requester. In addition, when a two-dimensional barcode is displayed on the in-car liquid crystal panel 41, a unique two-dimensional barcode may be created for each display, and input of the requester information may be omitted, and the process of S34 may be performed only when it is confirmed that the URL has been accessed correctly.

[0069] If the requester information is not entered correctly, the requester is prompted to enter it again. If the requester fails to enter the information several times, the requester may be deemed to have failed the identity verification.

[0070] If there is no LCD panel inside the car, the system accepts user access via a URL written on a two-dimensional barcode 40 for maintenance purposes attached to the inside of the car by a sticker or the like (S35).

[0071] Since the URL written on the two-dimensional barcode 40 for regular maintenance does not include elevator unit information, the operator transmits a random string of characters to the user by telephone 22 (S36), and the user is asked to enter the string on a screen opened by the two-dimensional barcode attached inside the car (S37).In addition to the random string of characters, the user's identity may also be verified by entering building information such as the building name or elevator unit information.

[0072] It is determined whether the character string received by the reception unit 34 of the information providing device matches the character string provided by the operator (S38), and if they match, the person is successfully identified.

[0073] If the passwords do not match, the system may retry several times, and if the number of retries exceeds a predetermined number, the system may consider the identity verification to have failed.

[0074] FIG. 5 is an example of a flowchart showing a process for setting the information disclosure range in an embodiment of the present invention.

[0075] The access authority update unit 37 determines whether or not the maintenance information 38 has been updated due to a fault report within a certain period of time (S40), and if a fault report has been issued, determines that the operating status of the building equipment for which the fault report was issued can be provided, and updates the access authority information 39 to allow access.

[0076] The access authority update unit 37 then determines whether the maintenance information 38 contains information indicating that the building facilities are out of service (S42), and if so, determines that a predicted recovery time can be provided, and updates the access authority information to allow access (S43).

[0077] The access authority update unit 37 then determines whether the maintenance information 38 includes an order to dispatch a maintenance technician to the site (S44), and if the maintenance technician needs to be dispatched to the site, determines that the dispatch status of the maintenance technician can be provided, and updates the access authority information 39 to allow access (S45).

[0078] If there is no need for a maintenance technician to be dispatched to the site, the access authority update unit 37 determines whether an inspection plan is included in the maintenance information 38 (S46), and if there is an inspection plan, determines that the inspection plan can be provided, and updates the access authority information 39 to allow access (S47). An example of this case would be when, after an elevator has stopped due to an earthquake, if an automatic diagnosis determines that temporary restoration is possible, the schedule for an inspection by a maintenance technician is notified and the elevator will be operating with temporary restoration.

[0079] If a fault report is issued but the maintenance information 38 does not include an inspection plan, the access authority update unit 37 determines that information indicating that a maintenance worker is not required can be provided, and updates the access authority information 39 to allow access (S48). This is the case when no work by a maintenance worker is required, such as when the elevator is stopped due to a power outage. Even if the elevator is stopped due to a power outage, if the elevator is equipped with an emergency battery, it is also possible to display the operating status of other nearby buildings.

[0080] In addition to the information described above, maintenance information that can be viewed by building managers, such as the status of other buildings in the event of a wide-area disaster or recovery information for other buildings, may also be provided depending on the maintenance status.

[0081] FIG. 6 is an example of a table showing the access authority information 39 in the embodiment of the present invention.

[0082] The building name 61, elevator number information 62 indicating the elevator number, maintenance information (item) 63 indicating the maintenance content, viewing authority 64 is stored in association with an administrator column 65 which is the viewing authority designated by the building administrator, and a user column 66 which indicates the access rights of users who have requested disclosure of progress and are authorized to view.

[0083] For example, if a user drops their key in the gap of an elevator and requests that it be retrieved, the elevator itself is in operation, so the only permission required is to view the status of maintenance personnel dispatch, similar to the access rights of User 2 for Unit B-1 in Building B.

[0084] However, even if viewing is permitted in the user column 66, if viewing is not permitted in the administrator column 65, the relevant information in the maintenance information 38 will not be provided.

[0085] FIG. 7 is an example of a table showing an elevator maintenance table in an embodiment of the present invention.

[0086] The building name 71, the unit number information 72, the maintenance information (item) 73 and the maintenance information 70 are stored in association with each other.

[0087] In this example, Unit A-1 in Building A is operating normally. Maintenance personnel were dispatched at 13:10 on 2024 / 1 / 29, and operation is expected to be restored at 14:30 on 2024 / 1 / 29. No inspections are scheduled.

[0088] The predicted restoration time refers to the predicted time when the elevator will resume operation, or the predicted time when a key that has been dropped from the elevator shaft pit will be retrieved if a user drops the key into the gap in the elevator.

[0089] FIG. 8 is an example of a table showing building information in an embodiment of the present invention.

[0090] The address 81 of the building in which the elevator is installed, elevator unit information 82, and whether or not a liquid crystal panel is installed inside the elevator car 83 are stored in association with each other.

[0091] When an inquiry is received from an elevator user, this table can be used to determine whether the operator needs to authenticate the user.

[0092] The building information may also include information such as the type of elevator maintenance contract in addition to the presence or absence of a liquid crystal panel.

[0093] FIG. 9 is a diagram showing an example of a screen of a user terminal in an embodiment of the present invention.

[0094] 10 is an example of a screen of a user terminal that is displayed when a user obtains access to elevator maintenance information and refers to the necessary information.

[0095] This example shows an example of a "Response Status Screen" 90. The request content 91 from the user, the name of the building where the requested elevator is installed 92, and the response status of the maintenance staff 93 are displayed in association with each other, and the screen may also be provided with a message display area 94 for displaying messages received from the operator or maintenance staff, and a message sending area 95 for sending messages to the operator or maintenance staff.

[0096] By displaying this information, the user can confirm whether the requested content, building, and elevator number are correct.

[0097] Furthermore, by checking the response status 93, the user can know what response is currently being taken and when the maintenance personnel are scheduled to arrive on-site without going through the building manager or operator.

[0098] In the example screen, response status 93 indicates that the request was accepted at 13:00 on January 29th, a maintenance worker was dispatched at 13:10 on January 29th, and is scheduled to arrive at the building at 13:30 on January 29th. [Explanation of symbols]
