Detailed Description

The elevator remote maintenance support system and the elevator remote maintenance support method according to the present invention will be described below with reference to the accompanying drawings.

Embodiment mode 1

Fig. 1 is an overall configuration diagram of an elevator remote maintenance support system according to embodiment 1 of the present invention. An elevator remote maintenance support system according to embodiment 1 shown in fig. 1 is configured to include an elevator control device 10, a center device 20 installed at a remote location different from a location where an elevator is installed, and a serviceman terminal 30 carried by a serviceman.

Although not shown, the center device 20 is connected to the elevator control device 10 and the serviceman terminal 30 via communication lines, respectively, and is configured to transmit and receive information to and from each other.

Next, the internal functions of the respective components will be described with reference to fig. 1. In fig. 1, one elevator control device 10 is illustrated, but the elevator control device is not limited to one, and may be a plurality of devices.

The elevator control device 10 is configured to have a fault log generator 11 and an operation information processor 12. The fault log generator 11 transmits fault information to the center device 20 every time an elevator fault occurs.

The operation information processor 12 analyzes the content of the recovery job performed by the maintenance person, and transmits the analysis result as operation information to the center device 20. As a specific example of the operation information, the following can be cited.

When the substrate replacement is performed as the recovery operation, the operation information processor 12 can read the version of the substrate and transmit the read version to the center device 20 as operation information actually executed by the maintenance person.

When the jumper (jumper) setting on the substrate or the setting of the knob switch on the substrate is changed as the recovery operation, the operation information processor 12 can read the setting information thereof and transmit the operation information to the center device 20 as the operation information actually executed by the maintenance person.

When the update job of the software is performed as the recovery job, the operation information processor 12 can read the version of the software and transmit the operation information to the center device 20 as the operation information actually executed by the maintenance person.

The center device 20 includes a data storage unit 21, an instruction information generator 22, a validity determiner 23, and a data updater 24. The data storage unit 21 stores in advance the contents of the recovery flow corresponding to each of the plurality of pieces of failure information as a correspondence table.

The content of the recovery procedure corresponding to the failure information stored in the correspondence table does not necessarily correspond to the failure information one by one, and a plurality of contents of the recovery procedure may be defined in advance for one failure information together with the priority order.

When receiving newly generated failure information from the failure log generator 11 in the elevator control device 10, the instruction information generator 22 extracts the content of the recovery flow corresponding to the generated failure information from the correspondence table in the data storage unit 21.

When a plurality of recovery flow contents are provided, the instruction information generator 22 generates instruction information to be transmitted to the maintenance staff after determining the priority order. The generated instruction information includes the contents of the extracted restoration flow, the elevator having the failure, and information for specifying the failure information that has occurred. The instruction information generator 22 transmits the generated instruction information to the validity determiner 23 and the serviceman terminal 30.

The validity determiner 23 determines the validity of the instruction information sent to the maintenance staff based on the result of comparison between the instruction information sent from the instruction information generator 22 and the operation information sent from the operation information processor 12 in accordance with the actual recovery job.

The validity determiner 23 may determine the validity of the instruction information by considering the result of evaluation of the instruction information by the maintenance person, which is acquired from an evaluation information processor 32 in the maintenance person terminal 30, which will be described later. The validity determiner 23 then transmits the result of the validity determination to the data updater 24. The specific validity determination method will be described later.

The data updater 24 updates the correspondence table in the data storage unit 21 in accordance with the instruction from the validity determiner 23. The specific update method will be described later.

The serviceman terminal 30 is configured to have a display 31 and an evaluation information processor 32. The display 31 displays the instruction information received from the instruction information generator 22 in the center device 20, and transmits the appropriate recovery procedure contents to the maintenance personnel together with the priority order. The maintenance personnel can obtain the contents of the recovery process before going to the setting site of the elevator, so that the maintenance personnel can rapidly go to the setting site with the components, measuring instruments, tools and the like required by the recovery.

The evaluation information processor 32 reads evaluation information input according to the judgment of the maintenance worker who actually performed the recovery work. Here, the evaluation information is information for evaluating whether or not the instruction information acquired from the center device 20 before the job matches the recovery job actually performed.

For example, when the maintenance person receives a plurality of pieces of instruction information with priority assigned thereto, if the instruction information corresponding to the first priority cannot be actually restored but the instruction information corresponding to the second priority is completely restored, the maintenance person can generate evaluation information (hereinafter referred to as evaluation information 1) indicating that the instruction information with priority 2 is most appropriate.

Further, when the maintenance person performs another recovery operation in accordance with the instruction information received in advance, the maintenance person can generate evaluation information (hereinafter referred to as evaluation information 2) for notifying the content of the operation in which the recovery operation is actually completed.

The evaluation information processor 32 feeds back evaluation information generated in accordance with an operation input by the maintenance worker to the center device 20. On the other hand, the validity determiner 23 in the center apparatus 20 considers the evaluation information fed back from the serviceman terminal 30 as necessary, and determines the validity of the instruction information based on the comparison result between the instruction information and the operation information. Therefore, a specific validity determination method will be described below.

Next, a specific validity determination method performed by the validity determiner 23 when the instruction information, the operation information, and the evaluation information are as follows will be described.

Indication information: the following is specified as the recovery flow content: the control substrate is changed from a substrate of version 1.1 to a substrate of version 1.2, a jumper 1 on the control substrate is set to an off state, and the setting of a rotary switch 1 is set to a range of 2 to 4 out of 0 to 9.

Operation information: the version of the control board is shown to be 1.2, and the jumper 1 on the control board is in an off state, and the setting of the rotary switch 1 is set to 5 out of 0 to 9.

Evaluation information: is generated based on the following: that is, according to the operation input by the operator, the version of the control board is 1.2, the bridge 1 is in the off state, and the setting of the knob switch 1 is not 4 which is actually set, but 3 which is set at the intermediate stage of the recovery operation is erroneously input.

The adequacy determiner 23 first compares the content of the instruction information transmitted to the maintenance worker for performing the restoration work with the operation information showing the actual state after the restoration work is performed, which is sent from the operation information processor 12 in the elevator control device 10.

In the above example, the adequacy determiner 23 can determine that the instruction information matches the operation information with respect to the version of the substrate and the setting state of the jumper 1, but can determine that the setting of the rotary switch 1 is 5 which is not included in the range of 2 to 4 transmitted as the instruction information.

Therefore, the validity determiner 23 can notify the data updater 24 of the result of such determination to change the data of the correspondence table so that 5 is included in the setting range of the rotary switch 1.

The adequacy determiner 23 can compare the operation information indicating the actual state after the resumption operation transmitted from the operation information processor 12 in the elevator control device 10 with the evaluation information input by the maintenance worker after the resumption operation.

In the above example, the adequacy determiner 23 can determine that the operation information matches the evaluation information with respect to the version of the substrate and the setting state of the jumper 1, but can determine that the operation information is 5 and is different from the evaluation information 3 with respect to the setting of the dial switch 1.

In this case, the validity determiner 23 can determine that the evaluation information input by the maintenance worker is based on the state in the middle of the maintenance work or an erroneous answer due to an erroneous opinion. That is, by effectively using the operation information that can be read by the elevator control device, the validity determiner 23 can grasp an accurate state that matches the actual recovery state to determine the validity of the instruction information, and then notify the data updater 24 of the updated correspondence table in the data storage unit 21.

The validity determiner 23 and the data updater 24 may be one component having both functions. The evaluation information processor 32 in the serviceman terminal 30 shown in fig. 1 is not an essential component. The elevator remote maintenance support system according to embodiment 1 can determine the validity of the instruction information by comparing the instruction information with the operation information even if the elevator remote maintenance support system does not include the evaluation information processor 32.

In addition, in the case where the elevator remote maintenance support system according to embodiment 1 further includes the evaluation information processor 32, information that cannot be read by the operation information processor 12 can be acquired as evaluation information fed back by a maintenance worker who actually performed a recovery operation, and the correspondence table can be updated based on the evaluation information. As a result, the table can be updated appropriately in a form reflecting the content of the recovery job actually performed, in accordance with 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 with reference to a flowchart. Fig. 2 is a flowchart summarizing an elevator remote maintenance support method according to embodiment 1 of the present invention.

In step S201, a correspondence table in which failure information and recovery flow contents are associated with each other is previously stored in the data storage unit 21 by a previous job. Next, in step S202, the instruction information generator 22 in the center device 20 determines whether or not failure information has been received from the elevator control device 10.

When determining that the failure information has been received, the instruction information generator 22 proceeds to the process of step S203, and when determining that the failure information has not been received, repeats the process of step S202 until the failure information has been received.

When the process proceeds to step S203, the instruction information generator 22 extracts the recovery flow content corresponding to the failure information received in step S202 from the correspondence table stored in the data storage unit 21. The instruction information generator 22 generates information including the failed elevator, the failure information, and the extracted contents of the recovery procedure, and transmits the information to the serviceman terminal 30 as instruction information.

Next, in step S204, the display 31 in the serviceman terminal 30 displays the instruction information received from the instruction information generator 22. Thus, the maintenance person who carries the maintenance person terminal 30 can quickly grasp what kind of failure has occurred in which elevator and what kind of recovery processing should be performed.

Next, in step S205, the maintenance person goes to the site where the failure occurred and performs an appropriate recovery operation based on the displayed information. The content of the restoration flow displayed on the display 31 includes not only the work to be actually performed on site but also information on the articles to be brought on site, such as parts, measuring instruments, and tools, which are required for restoration. Therefore, the maintenance person can go to the site after appropriate preparation according to the displayed content of the recovery flow.

Next, in step S206, after the recovery operation is performed, the maintenance person inputs the version of the substrate, the jumper 1 on the substrate, and the setting state of the rotary switch 1, which are specific examples, into the evaluation information processor 32. The evaluation information processor 32 feeds back the evaluation information input by the maintenance worker to the center device 20, which is the transmission source of the instruction information.

The maintenance staff can also input the evaluation information such as the above-described evaluation information 1 or evaluation information 2 to the evaluation information processor 32 and feed back the evaluation information to the center device 20.

Next, in step S207, the validity determiner 23 determines the validity of the instruction information based on the comparison between the operation information and the instruction information. Then, the validity determiner 23 instructs the data updater to update the correspondence table in the data storage unit 21 based on the determination result.

The validity determiner 23 may also consider evaluation information transmitted from the serviceman terminal 30 in response to an operation input by the serviceman when determining validity of the instruction information and when determining the necessity of updating the correspondence table.

Next, in step S208, the data updater 24 in the center apparatus 20 executes an update process based on an instruction from the validity determiner 23 as necessary on the content of the restoration flow referred to in step S203 from the correspondence table stored in the data storage unit 21.

As described above, embodiment 1 has the following structure: the validity of the instruction information transmitted to the maintenance person when the failure of the elevator occurs can be determined based on the result of comparison between the instruction information and the operation information transmitted from the elevator control device, the operation information being related to the state of the elevator after the maintenance person completes the recovery operation. Further, the table may be updated according to the determination result of validity. Further, the following structure can be added: in the update process of the correspondence table, evaluation information fed back from a maintenance worker who actually performed the recovery work is also considered.

As a result, the validity of the recovery work actually performed by the maintenance staff can be confirmed. Further, the response table can be updated to a more appropriate content as the results of the recovery work are accumulated, and the accuracy of the priority order of the specific recovery operation content can be improved. In addition, by using the optimized correspondence table, it is possible to quickly instruct an appropriate recovery operation from a remote place.

Embodiment mode 2

In embodiment 2, a configuration will be described in which a function of generating instruction information in consideration of the attribute of an elevator is added.

From the parameters such as "regional characteristics" and "building characteristics", it is considered that even when the same failure occurs in the elevator, the cause of the failure and the recovery method thereof differ depending on the parameters.

The "geographical 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 state and the number of times of starting of the elevator corresponding to the use environment such as an office building, an airport, and an apartment.

For example, considering the case where a failure in opening and closing operation of the door occurs, it is preferable to give priority to a failure recovery method around the door as instruction information for an object having a large number of starts. On the other hand, for an object with a small number of starts, it is preferable to give priority to oil adhesion and relay fixation (sticking) as instruction information.

Therefore, the elevator remote maintenance support system described in embodiment 2 is added with the following configuration: that is, by considering a parameter such as "regional characteristics" or "building characteristics", and generating individual instruction information according to the attribute of the parameter, it is possible to perform appropriate recovery work according to the installation environment even for the same failure cause.

Fig. 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 in embodiment 2 is different from the configuration of fig. 1 in embodiment 1 in that it further includes an identification information transmitter 13 in the elevator control device 10 and an attribute classifier 25 in the center device 20. In the configuration of fig. 3, a plurality of elevator control devices are described. Therefore, the following description will focus on these differences.

The identification information transmitter 13 transmits identification information including parameters relating to "regional characteristics" and "building characteristics" corresponding to the installation environment of the elevator to the center device 20. More specifically, the identification information transmitter 13 transmits, as the identification information, a parameter corresponding to the installation environment, such as a temperature condition or a frequency of use.

On the other hand, the attribute classifier 25 generates attribute information for specifying "regional characteristics" and "building characteristics" of the elevator to be remotely monitored, based on the identification information received from the identification information transmitter 13 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.

As described in embodiment 1, the data storage unit 21 stores in advance the contents of the recovery flow corresponding to each of the plurality of pieces of failure information as a correspondence table. However, the correspondence table according to embodiment 2 is provided for each of the attribute information items of the elevators classified by the attribute classifier 25.

When newly generated failure information is acquired from the failure log generator 11 in the elevator control device 10, the instruction information generator 22 extracts the content of the recovery flow corresponding to the generated failure information from the correspondence table in the data storage unit 21. The instruction information generator 22 according to embodiment 2 can extract appropriate recovery flow contents corresponding to failure information in consideration of the attribute information by referring to the correspondence table corresponding to the attribute information specified by the attribute classifier 25, and generate an instruction command.

The data updater 24 updates the correspondence table in the data storage unit 21 in accordance with the instruction from the validity determiner 23. The data updater 24 according to embodiment 2 updates the correspondence table corresponding to the attribute information specified by the attribute classifier 25.

As described above, the elevator remote maintenance support system according to embodiment 2 has the following configuration: even for the same failure information, the recovery flow contents are made different or the priority order is changed depending on the attribute (i.e., the number of times of activation in the above-described example), and thus a separate correspondence table corresponding to each attribute is provided. As a result, the validity of the instruction information presented to the maintenance staff is improved, and the maintenance staff can perform the failure recovery work more quickly.

The elevator remote maintenance support system according to embodiment 2 can verify validity of the instruction information generated in accordance with the attribute based on the evaluation information fed back from the maintenance staff, and correct the correspondence table in accordance with the restoration work actually effective when necessary. As a result, the validity of the correspondence table can be improved each time the actual results are accumulated.

As described above, according to embodiment 2, when a failure of an elevator occurs, even if the same failure cause is detected, it is possible to quickly instruct an appropriate recovery operation from a remote location in consideration of the attributes of the elevators corresponding to the installation environment.

Embodiment 3

In embodiment 3, a case will be described in which the instruction information transmitted from the center device 20 to the serviceman terminal 30 is changed and corrected in consideration of the skill of the serviceman. In embodiment 3, a configuration in which the skill of the maintenance worker is taken into consideration is added to the configuration of embodiment 2, but a similar configuration may be added to the configuration of embodiment 1.

Fig. 4 is an overall configuration diagram of an elevator remote maintenance support system according to embodiment 3 of the present invention. The configuration of fig. 4 in embodiment 3 is different from the configuration of fig. 3 in embodiment 2 in that a skill level information transmitter 33 is further provided in the serviceman terminal 30. Therefore, the following description will focus on this difference.

The proficiency level information transmitter 33 transmits proficiency level information showing the level of the serviceman carrying the serviceman terminal 30 to the center device 20. The proficiency information may be, for example, information classified into a plurality of levels, such as a house, a backbone, and a new person, based on experience of maintenance and recovery work. The skill information can be set by the maintenance person operating the maintenance person terminal 30.

On the other hand, the instruction information generator 22 according to embodiment 2 can change or correct the instruction information transmitted to the serviceman terminal 30 in accordance with the skill level of the serviceman determined based on the received skill level information.

For example, when a maintenance worker who is a traveler recovers a certain failure, a recovery method based on detailed inspection using a measurement instrument can be instructed. On the other hand, a maintenance person who is a new person can prevent the time taken for the recovery process from being lost by giving an instruction to replace the entire maintenance person in units of parts such as a substrate and a driver without requiring a detailed inspection. Further, the trouble cause can be found by separately performing detailed inspection of the substrate and the drive brought back by a maintenance person who is a traveler.

In addition, a case will be described in which the content of the recovery flow for performing the inspection of the detailed portion as described above is included in the correspondence table as the priority 1 and the content of the recovery flow for performing the substrate replacement as the priority 2. In this case, the instruction information generator 22 can reduce the recovery time by transmitting only the instruction information based on the priority order 2 to the maintenance person who is a new person.

On the other hand, the instruction information generator 22 can find the actual cause of the failure by detailed inspection by transmitting instruction information based on both the priority orders 1 and 2 to the maintenance worker who is a traveler.

As described above, embodiment 3 has the following structure: that is, indication information suitable for recovering from a failure is provided at the level of maintenance personnel. As a result, the maintenance worker who is a new person can quickly perform the recovery operation.

In addition, when the maintenance worker is a traveler, the site can be inspected in a short time to find the actual cause of the failure. As a result, the table can be updated according to the actual recovery processing, and valuable data for remote maintenance support from the next time can be collected.
