A detailed processing flow for transmitting support information to the mobile terminal 6 using the failure recovery support system 5 of the monitoring server 4 will be described with reference to FIGS. 4 and 5.

FIG. 2 is a functional block diagram of the failure recovery support system 5. In FIG. 2, based on the alarm information received from the failure site monitoring device 2 by the failure recovery support system 5, the data of the materials necessary for the failure recovery work from the databases DB1 to DB4 (hereinafter referred to as “document”). ) Is extracted, and the flow of data when scoring evaluation and feedback are given to the extracted document is indicated by an arrow. Further, FIG. 3 is a diagram showing a data structure of the failure recovery support system 5. FIG. 3 shows the types of data classified inside the storage unit 505 in the failure recovery support system 5 and their relationships with each other.

It also has document data 505d in which data of various materials extracted as documents from databases DB1 to DB4 of the in-house system are stored. That is, these data represent historical information of restoration work performed in the past.

The failure history data 505a has an actual ID, a report number, a property name, a model, and a failure code. It should be noted that the actual ID is assigned to each work actual based on, for example, the date and time so that the conditions do not overlap. In addition, the issue number is assigned to each property in advance. Further, the failure code is a code assigned to a failure assumed for each model of the elevator in advance at the specification stage.

The repair record data 505b has a record ID, a repair method, a failure occurrence time, a work time, and a person in charge. The repair method is a record of the work contents at the time of restoration work at the failure site by the worker.

The material usage history data 505c has an actual ID, a document ID, a property, a model, a failure code, a document comment, a marker date and time, and a user score. Among these, the user score is greatly related to giving priority to the support information to the mobile terminal 6, which will be described later. The document comment is a comment in which the worker adds various supplementary information to the document at the time of recovery work at the failure site. In addition, the document comment can be input even after the work. The marker date and time refers to, for example, the date and time when the document comment was recorded. The user score also indicates whether the document used by the worker was useful at the failure site.

The document data 505d has an actual ID, a document type, a source, and a citation number score. Among them, the number of citation scores is greatly related to giving priority to the support information to the mobile terminal 6, which will be described later. The source refers to identification information such as the creator and the creation date so that the source of the information data can be known, for example. In addition, the citation number score represents the citation frequency (reference frequency) of the document extracted to support the restoration work.

(2) Outline of Processing of Remote Monitoring System for Building Equipment Next, the outline of processing of the remote monitoring system for building equipment according to one embodiment of the present invention will be described with reference to FIG. Here, the data 505a to 505d held by the storage unit 505 in the failure recovery support system 5 and the processing performed by the processing unit 502 will be described.

The processing unit 502 processes the alarm data based on the alarm information from the elevator 1 received by the receiver 501, and registers each data item of the failure history data 505a related to the failure that occurred in the elevator 1 in the storage unit 505. ..

Further, the processing unit 502 performs a process of associating similar case data, which associates the failure that occurred in the elevator 1 with the past recovery work history based on the alarm information. Based on the result of this association processing, the data collection unit 504 acquires the document used in the failure case related to the failure of the elevator 1 represented by the notification information and the information related to the document from the databases DB1 to DB4. It is stored in the document data 505d.

Next, a past case search is performed using the repair record data 505b, the material usage history data 505c, and the document data 505d. In the past case search, the repair record data 505b and the material usage history data 505c are referred to, the document corresponding to the failure recovery work is acquired from the document data 505d, and the document is obtained by the operator during the past recovery work. The recorded document comment is acquired from the material usage history data 505c. At this time, if the narrowing conditions such as the part name of the failure target are specified, the optimum past cases may be further narrowed down and then acquired.

Next, the scoring module works after performing a past case search. The scoring module performs scoring evaluation on the documents acquired by the past case search, and assigns a priority score according to the evaluation result. The scoring evaluation is performed to determine the degree of association between each acquired document and the failure recovery work. For example, a high evaluation value is set as the scoring evaluation result for a document that is frequently referred to by past workers and a document that has been referred to in past failure cases that have a high degree of similarity to the failure that occurred in elevator 1. do. Further, the priority score means that when the support information transmitted from the monitoring server 4 to the mobile terminal 6 of the worker at the failure site is displayed on the screen of the mobile terminal 6, which information is preferentially displayed on the screen. It is for deciding whether to let it. Details will be described later.

The feedback module records the extraction result of the document extracted by the past case search corresponding to the failure recovery site and the result of the scoring evaluation performed by the scoring module in the material usage history data 505c and the document data 505d. do. In addition, documents and history information actually used at the failure site may be recorded during work, and such information may be stored as a user score or a citation number score in the material usage history data 505c and the document data 505d. When the worker describes supplementary information in the document, the supplementary information is stored as a document comment in the material usage history data 505c. In the feedback work, information may be additionally recorded not only during the work but also after the work.

(3) Details of Processing of Remote Monitoring System for Building Equipment FIG. 4 is a flowchart of processing operation performed by the failure recovery support system 5 of the monitoring server 4 when a failure of the elevator 1 occurs. Although the outline of the function of the failure recovery support system 5 has been described with reference to FIGS. 2 and 3, the details of the function of the failure recovery support system 5 will be described in the following flowchart.

In step S1, the receiving unit 501 receives the alarm information received by the communication unit 401 of the monitoring server 4 and recorded in the storage unit 402.

In step S2, the processing unit 502 processes the alarm data based on the alarm information received by the receiver 501 in step S1, so that the elevator 1 that transmits the alarm information has a specific failure location, an error code, or the like. Extracts the model information of the elevator 1 including the failure information, the serial number, and the property information such as the building name and location of the building. Then, these extracted information are recorded in the storage unit 505 as each data item of the failure history data 505a.

In step S3, the data collection unit 504 acquires available drawing data for the elevator 1 in which the failure has occurred from the database DB1 based on the model information obtained in step S2. In step S4, the data collection unit 504 acquires data such as a service manual and a maintenance procedure manual that can be used for the elevator 1 in which the failure has occurred from the data DB 3 based on the model information obtained in step S2.

In step S5, based on the failure information obtained in step S2, the failure location in the elevator 1 is estimated, and it is determined whether or not the estimated failure location is an electric circuit. If the relevant location is an electric circuit, in step S6, the data collection unit 504 acquires the wiring diagram data of the relevant location from the database DB2. If the relevant part is not an electric circuit, the process proceeds to step S7.

In step S7, based on the failure information obtained in step S2, it is determined whether or not the database DB 4 has maintenance history data for a failure case similar to the failure that occurred in the elevator 1. When the maintenance history data of the failure case similar to the failure exists in the database DB4, in step S8, the data collection unit 504 acquires the maintenance history data from the database DB4, and the failure case represented by the acquired maintenance history data. Data of materials such as drawings, service manuals, maintenance procedure manuals, etc. used in the case of the above are acquired from databases DB1 to DB3. After acquiring the data of these materials, the process proceeds to step S9. On the other hand, if it is determined in step S7 that a similar failure case does not exist, the process proceeds to step S11.

In step S9, the target range for searching and extracting maintenance history data in the database DB4 is narrowed as compared with step S7, and it is determined whether the maintenance history data for the failure case of the same model as the elevator 1 in which the failure occurred exists in the database DB4. judge. If the maintenance history data of the failure case in the same model exists in the database DB4, in step S10, the data collection unit 504 acquires the maintenance history data from the database DB4, and responds to the failure case represented by the acquired maintenance history data. Data of materials such as drawings, service manuals, and maintenance procedure manuals used at the time of the above are acquired from databases DB1 to DB3. As a result, regarding the failure that occurred in the elevator 1, as maintenance history data and document data in the failure case that is closer to the failure than the one extracted in step S8, the history of the response work of the failure case in the same model and the response It is possible to obtain materials such as drawings and maintenance procedure manuals used at the time. After acquiring these data, the process proceeds to step S11. Even if there is no failure case of the same model, the process proceeds to step S11.

In step S11, based on the failure information acquired in step S2, it is determined whether or not maintenance history data for the same failure case as the elevator 1 in which the failure has occurred exists in the database DB4. If the maintenance history data of the same model and the same failure case exists in the database DB4, the data collection unit 504 acquires the maintenance history data from the database DB4 in step S13, and the failure case represented by the acquired maintenance history data. Data of materials such as drawings, service manuals, maintenance procedure manuals, etc. used in the case of the above are acquired from databases DB1 to DB3. After acquiring these data, the process proceeds to step S14.

If it is determined in step S11 that the same failure case does not exist in the same model, the process proceeds to step S12, and maintenance history data for other failure cases in the same model as the elevator 1 in which the failure has occurred is searched from the database DB4. If maintenance history data of another failure case of the same model exists in the database DB4, the process proceeds to step S13, and in step S13, the data collection unit 504 acquires the maintenance history data from the database DB4 and the acquired maintenance history data. Data of materials such as drawings, service manuals, maintenance procedure manuals, etc. used in dealing with failure cases represented by are acquired from databases DB1 to DB3. After acquiring these data, the process proceeds to step S14. On the other hand, in step S12, if the maintenance history data for other failure cases of the same model does not exist in the database DB 4, the process proceeds to step S14 without acquiring the data.

In step S14, the processing unit 502 registers all the maintenance history data obtained in steps S6, S8, S10, and S13 in the storage unit 505 as repair record data 505b and material usage history data 505c. Further, the data of all the materials obtained in steps S6, S8, S10, and S13 are registered in the storage unit 505 as the document 505d. As a result, the processing of associating the similar case data is performed, the processing result is recorded in the repair record data 505b and the material usage history data 505c, and the document data based on the processing result is recorded in the document 505d. By doing so, the document data that is likely to be referred to in the restoration work can be prepared in advance before the worker who performs the restoration work of the elevator 1 arrives at the failure site, and then When another failure case occurs, the accuracy of acquiring the document corresponding to the failure site can be improved.

Next, a series of processing flows from the worker at the failure site acquiring the failure recovery support information using the mobile terminal 6 to using it in the recovery work will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing a processing procedure of the failure recovery support system 5 and the mobile terminal 6 at the time of recovery work.

In step S15, the mobile terminal 6 possessed by the worker at the failure site is connected to the control unit 503 of the failure recovery support system 5 via the general network 3. After connecting the mobile terminal 6 to the control unit 503, the operator inputs the issue number in step S16-A by operating the input unit 602, or in step S16-B, the model information, property information, inspection target part name, etc. The inquiry information is input to the mobile terminal 6 by inputting a word or using either method. The selection of either of these input methods can be performed by the operator on the input screen displayed on the output unit 603. The mobile terminal 6 requests the support information by transmitting the inquiry information input to the worker to the failure recovery support system 5.

In step S17, the failure recovery support system 5 searches the past case by the processing unit 502 based on the character string of the inquiry information input to the worker in step S16-A or S16-B and transmitted from the mobile terminal 6. I do. Here, the document data related to the inquiry information is searched from the document 505d by referring to the repair record data 505b and the material usage history 505c stored in the storage unit 505. If the document data related to the inquiry information exists in the document 505d of the storage unit 505, the processing unit 502 acquires all the corresponding document data from the storage unit 505 in step S18.

In step S19, the processing unit 502 performs a scoring evaluation on each document data acquired in step S18, assigns a priority score based on the evaluation result to each document data, and transmits the score to the mobile terminal 6. The data to which the priority score is given for each document data in this way is used as support information for recovery work for the failure of the elevator 1 represented by the notification information received by the monitoring server 4 in step S1 of FIG. It is transmitted to the mobile terminal 6 via 3.

The priority determined by the scoring evaluation performed in step S19 will be described. The priority score is information for displaying at least one of the display elements with priority over the other display elements on the display screens shown in FIGS. 7 and 8 described later. Therefore, the support information transmitted to the mobile terminal 6 includes a document composed of a plurality of pages, the history information registered in the storage unit 505 represents the reference frequency of each page of the document, and the monitoring server 4 indicates the history information. By performing the scoring evaluation based on, the priority can be determined for each page of the document included in the support information.

Further, the elevator 1 which is an example of the building equipment in which the restoration work is performed is configured to include a plurality of parts which are generally inspected in the restoration work. In the scoring evaluation, the monitoring server 4 can determine the priority for each description part of the document regarding each of the plurality of components. Further, the inspection of the elevator 1 included in the restoration work of the elevator 1 uses the measurement results of physical quantities (current, voltage, temperature, pressure, etc.) at a plurality of measurement points of the elevator 1 and any of a plurality of measurement methods. It may be performed based on the measurement result of a measurable physical quantity. In this case, the monitoring server 4 can determine the priority for each of the description points of the document relating to each of the plurality of measurement methods and the plurality of measurement points.

Based on the above determination of the priority, the document data extracted from the storage unit 505 in step S18 represents the priority on the display screen as support information for supporting the recovery work of the failure that occurred in the elevator 1. The data is transmitted from the failure recovery support system 5 to the mobile terminal 6 with the priority score assigned. After transmitting the support information in step S19, the process proceeds to step S21.

On the other hand, as a result of searching the storage unit 505 in step S17, if the document data related to the inquiry information does not exist in the document 505d of the storage unit 505, the process proceeds to step S20. In step S20, the failure recovery support system 5 transmits to the mobile terminal 6 that there is no corresponding information by the control unit 503. Further, the process proceeds to step S22, and when the communication unit 601 receives the information transmitted from the failure recovery support system 5 to the mobile terminal 6 in step S20, the mobile terminal 6 outputs and displays the information without the corresponding data to the output unit 603. ..

In step S21, the mobile terminal 6 waiting for the reception of the support information receives the support information transmitted from the failure recovery support system 5 in step S19. Then, a support screen composed of a plurality of display elements based on each document data included in the received support information is output and displayed on the output unit 603. At this time, in the output unit 603, the display element corresponding to the document data having a higher priority score given to the support information is preferentially displayed on the support screen. As a result, it is possible to provide useful support information when the worker performs the restoration work on the elevator 1, and to provide effective support for the restoration work.

In step S23, the worker feeds back information about the document used in the recovery work, for example, information such as the page number of the document referred to during the work and the work method from the mobile terminal 6 to the failure recovery support system 5. The feedback information transmitted from the mobile terminal 6 to the monitoring server 4 is output from the monitoring server 4 to the database DB 4 and registered in the database DB 4 as maintenance history data. As a result, information on the usage record of the support information in the recovery work of the elevator 1 is recorded in the database DB4 as maintenance history data, and when a failure of the elevator 1 occurs thereafter, appropriate support information is provided for the recovery work of the failure. Used to get.

The above steps are a series of processing flows of the remote monitoring system for building equipment according to the embodiment of the present invention.

This input screen is displayed on the output unit 603 in steps S16-A and B of FIG. 5, and thus acts as an input unit 602 for inputting inquiry information.

When the mobile terminal 6 is connected to the failure recovery support system 5 of the monitoring server 4 via the general network 3, the input screen of FIG. 6 for inputting inquiry information is displayed on the screen of the output unit 603.
