Embodiment 1

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 according to the first embodiment shown in Fig. 1 includes at least one elevator control device 10, a center device 20 installed at a remote place different from the place where the elevator is installed, And a repair source terminal 30 which is connected to the maintenance terminal 30.

Although not shown, the center device 20 is connected to each of the one or more elevator control devices 10 and the maintenance source terminal 30 via a communication line, and can transmit and receive information to / Respectively.

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

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

The identification information transmitter 12 transmits identification information including parameters relating to "regional characteristics" and "building characteristics" in accordance with the installation environment of the elevator to the center device 20. More specifically, the identification information transmitter 12 transmits a parameter according to the installation environment such as a temperature condition and a frequency of use 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 the contents of the recovery procedure associated with each of the plurality of pieces of failure information as a response table.

The coping table in the first embodiment is characterized in that it is provided separately for each attribute of the elevator classified by the property classifier 23 described later. In addition, the content of the recovery procedure stored in the response table, which is associated with the failure information, is not necessarily one-to-one with the failure information, and a plurality of recovery procedures can be specified with priority in relation to one failure information.

When the newly generated fault information is obtained from the fault log generator 11 in the elevator control device 10, the instruction information generator 22 generates recovery information corresponding to the fault information generated in the countermeasure table in the data storage unit 21 Take the procedure contents. The instruction information generator 22 considers the attribute information by referring to the coping table corresponding to the attribute information specified by the attribute classifier 23 described later, and then retrieves the contents of the appropriate recovery procedure corresponding to the failure information .

When there are a plurality of contents of the restoration procedure, the instruction information generator 22 specifies the priority and then generates instruction information to be transmitted to the conservator. Here, the generated instruction information includes information for specifying the failed elevator and the generated failure information, together with the extracted recovery procedure contents. In addition, the instruction information generator 22 transmits the generated instruction information to the maintenance terminal 30.

The attribute classifier 23 generates attribute information specifying the "local characteristic" and the "building characteristic" relating to the elevator of the remote monitoring target, based on the identification information received from the identification information transmitter 12 in the elevator control device 10 do. The generated attribute information can be referred to by the instruction information generator 22 and the data updater 24.

The data updator 24 is based on the result of the evaluation by the conservative source for the instruction information and the attribute information specified by the attribute classifier 23, which are acquired from the evaluation information processor 32 in the follower terminal 30 , And updates the coping table in the data storage unit (21). The concrete update method will be described later.

The maintenance source terminal 30 includes a display device 31 and an evaluation information processor 32. The display device 31 displays the instruction information received from the instruction information generator 22 in the center device 20, and delivers the contents of the appropriate restoration procedure to the maintenance source along with the priority. The repair worker can get the restoration procedure contents before going to the elevator installation site, so that he can bring the necessary parts for repair, measuring instrument, tools and so on to the installation place quickly.

The evaluation information processor 32 reads out the evaluation information inputted by the judgment of the repair source actually performing the recovery operation. Here, the evaluation information is information for evaluating whether or not the instruction information acquired before the operation from the center apparatus 20 matches the actual operation performed.

For example, when the maintenance source has received a plurality of pieces of instruction information to which a priority has been assigned, actually, the instruction information corresponding to the first priority can not be restored, and the instruction information of the second priority (Hereinafter, referred to as evaluation information 1) for notifying that the instruction information of priority 2 has been most appropriate can be created.

In addition, the repair source can not recover the instruction information that has been received in advance, and in the case where the restoration work is performed, evaluation information (hereinafter, referred to as evaluation information 2) for conveying the actual work contents that can be restored ) Can be created.

The evaluation information processor 32 then feeds back the evaluation information generated by the operation input of the maintenance source to the center device 20. [ On the other hand, the data updater 24 in the center device 20 updates the coping table in the data storage 21 based on the evaluation information fed back from the assistant terminal 30. [ Hereinafter, a specific update method will be described.

In the following, an update method when the data updater 24 receives the above-described evaluation information 1 and evaluation information 2 as evaluation information will be described as a specific example.

When the evaluation information 1 indicating that the instruction information of priority 2 is the most appropriate is received, the data updater 24 updates the priority order of the plurality of recovery procedure contents stored in the coping table in correspondence with this failure information, 1 and the priority 2 can be changed to change the data of the coping table.

Alternatively, when the evaluation information 1 is received, the data updater 24 determines whether or not the repair source corresponds to the priority 2 actually used by the maintenance source with respect to the plurality of recovery procedure contents stored in the coping table in correspondence with the present failure information With respect to the content of the recovery procedure, the number of records of performance can be counted up by +1, and the number of records of performance can be stored as one piece of data of the coping table.

Then, the data updater 24 can accumulate the performance, change the priority order in descending order of the number of times of performance, and change the data of the coping table.

The data updater 24 can not recover the instruction information previously transmitted from the center device 20 and, when receiving the evaluation information 2 that conveys the actual new work content that has been recovered, It is possible to change the data of the coping table by adding a new work content specified by the evaluation information 2 to a plurality of recovery procedure contents stored in the coping table in correspondence with the information.

Also, when the evaluation information 2 is received, as in the case of the evaluation information 1, the number of records of performance is also stored as one piece of data in the coping table, the priority is changed in accordance with the number of times of performance, .

The data updater 24 in the center device 20 shown in Fig. 1 and the evaluation information processor 32 in the repairer terminal 30 are not essential constituent elements. The elevator remote maintenance support system according to the first embodiment can prevent the elevator from being damaged even when the elevator malfunctions due to the configuration without the data updater 24 and the evaluation information processor 32, It is possible to promptly designate the appropriate restoration work from the remote place after taking into consideration the individual attributes of the elevator according to the elevator.

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 includes the evaluation information fed back from the maintenance worker , The coping table can be updated. As a result, it is possible to realize the appropriateness of the coping table in consideration of the attribute by the learning effect.

Next, a series of processes executed in the elevator remote maintenance support system corresponding to the configuration of Fig. 1 will be described based on a flowchart. 2 is a flow chart summarizing an elevator remote maintenance support method according to the first embodiment of the present invention.

In step S201, the response table in which the failure information and the restoration procedure contents are associated is stored in the data storage unit 21 by the preliminary work. The coping table is separately prepared for each attribute in advance and stored in the data storage unit 21. [ Next, in step S202, the instruction information generator 22 in the center device 20 determines whether any one of the elevator control devices 10 has received the fault information.

If the instruction information generator 22 determines that the failure information has been received, the process proceeds to step S203. If the failure information is not received, the instruction information generator 22 performs the process of step S202 until failure information is received I repeat.

When the process proceeds to step S203, the property classifier 23 receives the identification information transmitted from the elevator control device 10 as the transmission source of the failure information. The attribute classifier 23 generates attribute information based on the received attribute information.

Next, in step S204, the instruction information generator 22 specifies a coping table corresponding to the attribute information generated in the attribute classifier 23, among the coping tables stored in the data storage unit 21. [ Further, the instruction information generator 22 extracts the contents of the recovery procedure corresponding to the failure information received in step S202 from among the specific response tables. Then, the instruction information generator 22 generates information including the failed elevator, the generated fault information, and the retrieved restoration procedure contents as instruction information, and transmits the instruction information to the repairer terminal 30.

Next, in step S205, the display device 31 in the repair source terminal 30 displays the instruction information received from the instruction information generator 22. [ As a result, the maintenance source carrying the repair source terminal 30 can quickly grasp which fault occurs in which elevator and what restoration process should be performed.

Next, in step S206, the repair source performs an appropriate restoration operation based on the displayed information toward the site where the failure has occurred. The content of the recovery procedure displayed on the display 31 includes not only the work to be actually performed in the field but also information on parts to be brought back to the site, such as parts for measurement, measuring instruments, and tools. Therefore, the maintenance worker can make appropriate preparations based on the contents of the indicated recovery procedure, and then go to the site.

Next, in step S207, the repair source inputs evaluation information such as the above-described evaluation information 1 or evaluation information 2 to the evaluation information processor 32 as a specific example after the recovery operation is performed. Then, the evaluation information processor 32 feeds back the evaluation information inputted by the maintenance source to the center apparatus 20 which is the transmission source of the instruction information.

Next, in step S208, the data updater 24 in the center device 20 stores a coping table corresponding to the attribute information generated in the attribute classifier 23, among the coping tables stored in the data storing unit 21 Specify. Further, the data updater 24 executes update processing based on the feedback evaluation information, as necessary, with respect to the contents of the recovery procedure referred to in step S204, from among the specific response tables.

The concrete effects of considering the attribute information will be described in a supplementary manner. Even when the same trouble occurs, for example, the cause of the trouble may be different due to the difference in attributes such as the number of times of starting and the number of times of starting.

As an example, in the case where the opening / closing operation failure of the door occurs, it is appropriate to give priority to the failure recovery method around the door in the case of an object having a large number of startup times as the instruction information. On the other hand, in the case of an article having a small number of maneuvering, it is appropriate to give priority to oil sticking, relay sticking, and the like as instruction information.

Therefore, the elevator remote maintenance support system according to the first embodiment can make the contents of the restoration procedure different, or preferentially change the priority, in accordance with the difference in attribute (i.e., the number of startup times in the above example) By changing the ranking, an individual coping table suited to each attribute is provided. As a result, the legitimacy of the instruction information to be presented to the maintenance person is improved, and the repairer can more quickly perform the fault recovery operation.

The elevator remote maintenance support system according to the first embodiment verifies the legitimacy of the instruction information generated according to the attribute based on the evaluation information fed back from the maintenance source and adjusts the coping table as needed Can be modified based on the recovery operation, and updated in sequence. As a result, the fairness of the coping table can be improved as the performance is repeated.

As described above, according to the first embodiment, it is possible to promptly designate an appropriate restoration work from the remote place, taking into consideration the individual attributes of the elevator according to the installation environment, when the elevator has a failure, and also with respect to the same failure factor.

Further, it is possible to additionally add a configuration for updating the coping table based on the evaluation information fed back from the maintenance worker who actually performed the restoration work. As a result, it is possible to realize the appropriateness of the coping table in consideration of the attribute by the learning effect.

Embodiment 2 Fig.

In the second embodiment, a case where the instruction information to be transmitted from the center apparatus 20 to the repair source terminal 30 is changed or corrected in consideration of the skill level of the maintenance source will be described.

3 is an overall configuration diagram of an elevator remote maintenance support system according to Embodiment 2 of the present invention. The configuration of FIG. 3 according to the second embodiment differs from the configuration of FIG. 1 according to the first embodiment in that a skill level information transmitter 33 is additionally provided in the repair source terminal 30 Do. Hereinafter, this difference will be mainly described.

The skill level information transmitter 33 transmits skill level information indicating the level of a repair source carrying the repairer terminal 30 to the center device 20. [ As the proficiency information, information classified into a plurality of levels such as a veteran, a middle-class, and a freshman can be cited as an example according to the experience of the repair and restoration work. The skill level information can be set by the repairer himself or herself by operating the repairer terminal 30.

On the other hand, the instruction information generator 22 in the second embodiment changes or changes the instruction information to be transmitted to the repair source terminal 30 in accordance with the level of the proficiency level of the repair source specified from the received skill level information .

For example, with respect to a veteran conservative source, it is possible to instruct a recovery method based on a detailed check using a gauge to recover from a failure. On the other hand, with respect to the fresh-entry repair source, it is possible to prevent the recovery process from taking a long time by instructing replacement of the whole new repair source in units of parts such as a board and a driver without requiring a detailed check. In addition, the board and driver taken back can be searched by a veteran repairer separately to check the cause of the failure.

It is also assumed that the contents of the recovery procedure for checking details as described above are of priority 1, and the contents of the recovery procedure for exchanging substrates are included in the response table as priority 2. In this case, the instruction information generator 22 can transmit the instruction information based on the priority 2 to the new-arrived repair source, thereby making it possible to shorten the restoration time.

On the other hand, the instruction information generator 22 can carry out a search for a genuine cause of the failure based on the detailed check by transmitting both instruction information based on the priorities 1 and 2 to the veteran conservator.

As described above, according to the second embodiment, there is provided a configuration capable of providing appropriate instruction information in accordance with the level of the maintenance source in order to restore the failure. As a result, it is possible to quickly perform the restoration work by the fresh-entry maintenance worker.

In the case where the maintenance source is a veteran, a detailed check at the site can be executed in a short time, so that a true cause of the failure can be searched. As a result, it is possible to update the coping table on the basis of the actual recovery countermeasure, thereby collecting valuable data for remote maintenance support from the next meeting.
