However, the prior art has the following problems.
Even when the same failure occurs due to parameters such as “regional characteristics” or “building characteristics”, it is conceivable that the cause of failure and the recovery method of the elevator differ depending on the parameters.

  Here, the “regional characteristics” correspond to parameters such as temperature conditions and humidity conditions depending on the installation environment of the elevator. The “building characteristics” correspond to parameters such as the operation status of the elevator and the number of activations according to the use environment such as an office, an airport, and an apartment.

  For example, let us consider a case where a failure of contact failure has occurred in which the relay contact does not operate normally. In this case, if the frequency of use of the relay is approaching a certain allowable number of times, it is considered that the relay needs to be replaced because the life is approaching.

  However, such allowable times vary depending on “regional characteristics” and “building characteristics” and are not uniform. Also, for contact failures caused by low usage frequency, or contact failures caused by factors such as dew condensation in cold regions, it is possible that the same failure will reoccur simply by replacing the relay, It may be necessary to take other measures.

  Hereinafter, preferred embodiments of an elevator remote maintenance support system and an elevator remote maintenance support method of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is an overall configuration diagram of an elevator remote maintenance support system according to Embodiment 1 of the present invention. The elevator remote maintenance support system in the first embodiment shown in FIG. 1 includes one or more elevator control devices 10, a center device 20 installed in a remote location different from the location where the elevator is installed, and maintenance personnel. Is provided with a maintenance staff terminal 30 that is carried.

  In addition, although illustration is abbreviate | omitted, the center apparatus 20 is connected with each of the 1 or more elevator control apparatus 10 and the maintenance staff terminal 30 via a communication line, and can transmit / receive information mutually. It has a configuration.

  Next, the internal functions of each component will be described with reference to FIG. The one or more elevator control devices 10 all have the same configuration and function, and in the following description, one elevator control device will be described.

  The elevator control device 10 includes a failure log generator 11 and an identification information transmitter 12. The failure log generator 11 transmits failure information to the center device 20 every time a failure occurs in the elevator.

  In addition, the identification information transmitter 12 transmits identification information including parameters related to “regional characteristics” and “building characteristics” according to the installation environment of the elevator to the center device 20. More specifically, the identification information transmitter 12 transmits parameters according to the installation environment such as temperature conditions and use frequency as identification information.

  The center apparatus 20 includes a data storage unit 21, an instruction information generator 22, an attribute classifier 23, and a data updater 24. The data storage unit 21 stores in advance recovery procedure contents associated with each of a plurality of pieces of failure information as a countermeasure table.

  The countermeasure table in the first embodiment is characterized in that it is individually provided for each elevator attribute classified by the attribute classifier 23 described later. In addition, the recovery procedure contents associated with the failure information stored in the countermeasure table are not necessarily one-to-one with the failure information, and a plurality of recovery procedure contents with a priority order are defined for one failure information. I can leave.

  When the instruction information generator 22 obtains newly generated failure information from the failure log generator 11 in the elevator control device 10, the instruction information generator 22 converts the generated failure information from the countermeasure table in the data storage unit 21. Retrieve the corresponding recovery procedure. The instruction information generator 22 refers to a countermeasure table corresponding to the attribute information specified by the attribute classifier 23 described later, and takes appropriate attribute information into consideration, and the contents of an appropriate restoration procedure corresponding to the failure information. Can be taken out.

  Then, when there are a plurality of restoration procedure contents, the instruction information generator 22 specifies the priority order and then generates instruction information to be communicated to maintenance personnel. Here, the generated instruction information includes information for identifying the failed elevator and the failure information that has occurred along with the extracted recovery procedure content. Further, the instruction information generator 22 transmits the generated instruction information to the maintenance staff terminal 30.

  The attribute classifier 23 generates attribute information for specifying “regional characteristics” and “building characteristics” related to the remotely monitored elevator based on the received identification information received from the identification information transmitter 12 in the elevator control device 10. The generated attribute information can be referred to by the instruction information generator 22 and the data updater 24.

  The data updater 24 is a data storage unit based on the evaluation result by the maintenance staff for the instruction information acquired from the evaluation information processor 32 in the maintenance staff terminal 30 described later and the attribute information specified by the attribute classifier 23. The countermeasure table in 21 is updated. A specific update method will be described later.

  The maintenance staff terminal 30 includes a display device 31 and an evaluation information processing device 32. The display 31 displays the instruction information received from the instruction information generator 22 in the center device 20, thereby transmitting appropriate restoration procedure contents together with priority to maintenance personnel. The maintenance staff can acquire the contents of the restoration procedure before going to the elevator installation site, and can bring the parts, measuring instruments, tools, etc. necessary for the restoration and rush to the installation site.

  The evaluation information processor 32 reads the evaluation information input based on the judgment of the maintenance staff who actually performed the restoration work. Here, the evaluation information is information for evaluating whether the instruction information acquired from the center device 20 before the work matches the actual restoration work.

  For example, when the maintenance staff receives a plurality of instruction information with priorities, the maintenance information cannot actually be recovered with the instruction information corresponding to the first priority. If the information can be recovered, it is possible to create evaluation information (hereinafter referred to as evaluation information 1) for transmitting that the priority order 2 instruction information is most appropriate.

  In addition, maintenance personnel cannot recover with the instruction information received in advance, and when other recovery work is performed, evaluation information for transmitting the actual work content that was recovered (Hereinafter referred to as evaluation information 2) can be created.

  Then, the evaluation information processor 32 feeds back the evaluation information created by the operation input of the maintenance staff to the center apparatus 20. On the other hand, the data updater 24 in the center device 20 updates the handling table in the data storage unit 21 based on the evaluation information that is food-backed from the maintenance staff terminal 30. Therefore, a specific update method will be described below.

  Below, the update method in case the data updater 24 receives the evaluation information 1 and the evaluation information 2 mentioned above as evaluation information is demonstrated as a specific example.

  When the data updater 24 receives the evaluation information 1 indicating that the instruction information of the priority order 2 is most appropriate, the data updater 24 stores a plurality of restoration procedures stored in the countermeasure table corresponding to the current failure information. Regarding the contents, the data in the countermeasure table can be changed by switching the priority order 1 and the priority order 2.

  Alternatively, when the data updater 24 receives the evaluation information 1, the priority level 2 actually used by the maintenance personnel with respect to the contents of the plurality of restoration procedures stored in the countermeasure table corresponding to the current failure information As for the contents of the recovery procedure corresponding to, the actual number of times can be incremented by +1, and the actual number of times can be stored as one data in the handling table.

  Then, the data updater 24 can change the data of the countermeasure table by accumulating the results and changing the priority order in descending order of the number of results.

  Further, when the data updater 24 cannot receive the instruction information transmitted in advance from the center device 20 and receives the evaluation information 2 that conveys the actual new work content that has been recovered, The data of the countermeasure table is changed by adding new work contents specified by the evaluation information 2 with respect to a plurality of recovery procedure contents stored in the countermeasure table corresponding to the current failure information. Can do.

  Also, when the evaluation information 2 is received, as in the case of the evaluation information 1, the actual number of times is stored as one data of the handling table, and the priority order is changed according to the actual number of times, It is also possible to change data in the response table.

  Note that the data updater 24 in the center device 20 and the evaluation information processor 32 in the maintenance staff terminal 30 shown in FIG. 1 are not indispensable constituent requirements. In the elevator remote maintenance support system according to the first embodiment, even in the configuration where the data updater 24 and the evaluation information processor 32 are not provided, even when an elevator failure occurs, the same failure factor depends on the installation environment. In consideration of the attributes of each elevator, it is possible to promptly prompt an appropriate restoration work from a remote location.

  In addition, when the elevator remote maintenance support system according to the first embodiment further includes the data updater 24 and the evaluation information processor 32, the elevator remote maintenance support system is based on evaluation information fed back from the maintenance staff who actually performed the restoration work. The handling table can be updated. As a result, due to the learning effect, it is possible to realize an appropriate countermeasure table in consideration of attributes.

  Next, a series of processes executed by the elevator remote maintenance support system corresponding to the configuration of FIG. 1 will be described based on a flowchart. FIG. 2 is a flowchart summarizing the elevator remote maintenance support method according to Embodiment 1 of the present invention.

  In step S <b> 201, a countermeasure table in which failure information is associated with recovery procedure contents is stored in the data storage unit 21 in advance. Note that the countermeasure table is individually created for each attribute and stored in the data storage unit 21. Next, in step S <b> 202, the instruction information generator 22 in the center apparatus 20 determines whether failure information has been received from any one or more elevator control apparatuses 10.

  If the instruction information generator 22 determines that the failure information has been received, the process proceeds to step S203. If the instruction information generator 22 determines that the failure information has not been received, the instruction information generator 22 proceeds to step S202. Will be repeated.

  When it progresses to step S203, the attribute classifier 23 receives the identification information transmitted from the elevator control apparatus 10 which is a transmission source of failure information. Then, the attribute classifier 23 generates attribute information based on the received attribute information.

  Next, in step S <b> 204, the instruction information generator 22 specifies a handling table corresponding to the attribute information generated by the attribute classifier 23 from the handling table stored in the data storage unit 21. Further, the instruction information generator 22 extracts the recovery procedure content corresponding to the failure information received in step S202 from the identified countermeasure table. Then, the instruction information generator 22 creates information including the failed elevator, the occurring failure information, and the extracted recovery procedure content as instruction information, and transmits the instruction information to the maintenance staff terminal 30.

  Next, in step S <b> 205, the display 31 in the maintenance staff terminal 30 displays the instruction information received from the instruction information generator 22. As a result, the maintenance person carrying the maintenance person terminal 30 can quickly grasp what kind of failure has occurred in which elevator and what kind of restoration processing should be performed.

  Next, in step S206, based on the displayed information, the maintenance staff goes to the site where the failure has occurred and performs appropriate recovery work. The contents of the restoration procedure displayed on the display 31 include not only the work that should actually be performed on the site, but also information on items that should be brought to the site, such as parts, measuring instruments, and tools necessary for the restoration. Therefore, the maintenance staff can go to the site after making appropriate preparations based on the displayed contents of the recovery procedure.

  Next, in step S207, the maintenance staff inputs evaluation information such as the evaluation information 1 or the evaluation information 2 described above as a specific example to the evaluation information processor 32 after performing the restoration work. Then, the evaluation information processor 32 feeds back the evaluation information input by the maintenance staff to the center device 20 that is the transmission source of the instruction information.

  Next, in step S <b> 208, the data updater 24 in the center device 20 specifies a handling table corresponding to the attribute information generated by the attribute classifier 23 from the handling table stored in the data storage unit 21. To do. Further, the data updater 24 executes an update process based on the feedback evaluation information as necessary for the recovery procedure content referred to in step S204 from the identified countermeasure table.

  A supplementary explanation will be given of specific effects of considering attribute information. Even when the same failure occurs, the cause of the failure may differ due to a difference in attributes such as a property with a large number of activations and a property with a small number of activations.

  As an example, considering a case where a door opening / closing operation failure occurs, it is appropriate to preferentially present a failure recovery method around the door as instruction information in a property with a large number of activations. On the other hand, it is appropriate to preferentially present oil sticking, relay sticking, etc. as instruction information for properties with a small number of activations.

  Therefore, the elevator remote maintenance support system according to the first embodiment varies the contents of the recovery procedure for the same failure information depending on the difference in attributes (that is, the number of activations in the above example). Or, by changing the priority order, it is configured to have an individual handling table suitable for each attribute. As a result, the legitimacy of the instruction information presented to the maintenance staff is increased, and the maintenance staff can perform the failure recovery work more quickly.

  Further, the elevator remote maintenance support system according to the first embodiment verifies the validity of the instruction information generated according to the attribute based on the evaluation information fed back from the maintenance staff, and if necessary, provides a countermeasure table. Then, it can be corrected and updated sequentially based on the recovery work that was actually effective. As a result, it is possible to improve the legitimacy of the handling table every time the results are accumulated.

  As described above, according to the first embodiment, when an elevator failure occurs, an appropriate restoration work is performed for the same failure factor in consideration of the individual attributes of the elevator according to the installation environment. It becomes possible to promptly instruct from a remote place.

  Furthermore, it is possible to further add a configuration for updating the countermeasure table based on evaluation information fed back from maintenance personnel who actually performed the restoration work. As a result, due to the learning effect, it is possible to realize an appropriate countermeasure table in consideration of attributes.

Embodiment 2. FIG.
In the second embodiment, a case will be described in which instruction information transmitted from the center apparatus 20 to the maintenance staff terminal 30 is changed or corrected in consideration of the skill level of the maintenance staff.

  FIG. 3 is an overall configuration diagram of the elevator remote maintenance support system according to the second embodiment of the present invention. The configuration of FIG. 3 in the second embodiment is different from the configuration of FIG. 1 in the first embodiment in that a skill level information transmitter 33 is further provided in the maintenance staff terminal 30. . Therefore, this difference will be mainly described below.

  The skill level information transmitter 33 transmits skill level information indicating the level of the maintenance staff carrying the maintenance staff terminal 30 to the center apparatus 20. As this skill level information, for example, information divided into a plurality of levels such as experienced, mid-career, and newcomer according to the experience of maintenance and recovery work can be cited. Such skill level information can be set by operating the maintenance staff terminal 30 by the maintenance staff.

  On the other hand, the instruction information generator 22 according to the second embodiment changes or corrects the instruction information transmitted to the maintenance staff terminal 30 according to the level of skill of the maintenance staff identified from the received skill level information. It can be performed.

  For example, it is possible to instruct a veteran maintenance staff for a restoration method based on a detailed check using an instrument in order to restore a certain failure. On the other hand, new maintenance personnel are not required to make detailed checks. For example, the maintenance staff is instructed to replace the entire unit, such as a board or driver, to prevent the recovery process from taking a long time. be able to. It should be noted that the board and driver brought back can be investigated by a detailed maintenance check by an experienced maintenance person.

  Further, consider the case where the restoration procedure contents for performing the detailed check as described above are included in the handling table as priority order 1 and the restoration procedure contents for performing board replacement are included as priority order 2. In this case, the instruction information generator 22 can shorten the recovery time by transmitting only the instruction information based on the priority order 2 to the new maintenance staff.

  On the other hand, the instruction information generator 22 can investigate the cause of the true failure through detailed checks by transmitting both instruction information based on the priorities 1 and 2 to the experienced maintenance staff. .

  As described above, according to the second embodiment, there is provided a configuration capable of providing appropriate instruction information for restoring a failure according to the level of the maintenance staff. As a result, recovery work by a new maintenance person can be performed quickly.

  In addition, when the maintenance staff is experienced, it is possible to investigate the true cause of the failure by executing a detailed check in the field in a short time. As a result, the response table can be updated in accordance with the actual recovery response, and valuable data for remote maintenance support from the next time can be collected.
