  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
The failure diagnosis apparatus, system, and method according to the first embodiment will be described with reference to FIGS. The failure diagnosis device according to the present embodiment diagnoses a failure of the elevator device based on the time difference between the ideal timing and the actual timing.

  First, a functional configuration of a failure diagnosis apparatus 100 (hereinafter referred to as “apparatus 100”) according to the first embodiment will be described with reference to FIGS. FIG. 1 is a block diagram illustrating a functional configuration of the apparatus 100. As shown in FIG. 1, the apparatus 100 includes a specification acquisition unit 1, an ideal timing acquisition unit 2, a failure diagnosis unit 3, a failure information DB 4, a failure site identification unit 5, a circuit diagram acquisition unit 6, and a notification. Part 7.

  The specification acquisition unit 1 acquires specifications of an elevator apparatus (hereinafter referred to as “target EV”) that is a target of failure diagnosis among one or a plurality of elevator apparatuses EV included in the elevator equipment 200 of the building. First, the elevator facility 200 will be described.

  The elevator facility 200 includes one or a plurality of elevator apparatuses EV, a control panel 201 that controls the operation of each elevator apparatus EV, and an identification information acquisition apparatus 202. In FIG. 1, elevator devices EV <b> 1 and EV <b> 2 are illustrated, but the number of elevator devices EV included in the elevator facility 200 is arbitrary.

  The control panel 201 controls the operation of each elevator apparatus EV by transmitting an operation command. The operation command is a command that specifies an operation performed by the elevator apparatus EV. The elevator apparatus EV performs an operation specified by the received operation command.

  In addition, the control panel 201 always acquires the state of each elevator apparatus EV from a sensor or the like provided in the elevator apparatus. The state of the elevator apparatus EV includes, but is not limited to, at least one of a car position (floor), a load weight, a lifting speed, and a call.

  Each elevator apparatus EV includes an individual identification apparatus 203. The individual identification device 203 stores identification information (ID) for individually identifying the elevator apparatus EV. The individual identification device 203 is, for example, an IC chip or an IC tag, but is not limited thereto.

  The identification information acquisition device 202 acquires identification information from the individual identification device 203 of the target EV. The identification information acquisition device 202 transmits the identification information of the target EV acquired from the individual identification device 203 to the device 100.

  The control panel 201 and the identification information acquisition device 202 can communicate with the device 100 by wire or wireless, and constitute a failure diagnosis system together with the device 100.

  The specification acquisition unit 1 acquires the specification of the target EV based on the identification information acquired from the identification information acquisition device 202. The specification acquisition unit 1 includes a specification DB 11 and a specification extraction unit 12.

  The specification DB 11 stores the specifications of each elevator apparatus EV included in the elevator facility 200. The specification stored in the specification DB 11 is, for example, at least one of a model, an ascending / descending speed, an installation floor, and regenerative power, but is not limited thereto.

  Here, FIG. 2 is a diagram illustrating an example of a specification table (specification information) stored in the specification DB 11. In FIG. 2, the record of each elevator apparatus EV includes three specifications: model, lifting speed, and installation floor. According to FIG. 2, for example, the model of the elevator apparatus EV1 is A.

  The specification extraction unit 12 acquires the identification information of the target EV from the identification information acquisition device 202, and extracts the specification information corresponding to the acquired identification information from the specification DB 11. For example, when the identification information (ID = EV1) of the elevator apparatus EV1 is acquired, the specification extraction unit 12 extracts the record of EV1 from the specification table of FIG. Thereby, the model A, the raising / lowering speed 30, and the installation floors 1 to 10 are extracted as the specifications of the target EV.

  The ideal timing acquisition unit 2 acquires ideal timing. The ideal timing is a time that satisfies a predetermined condition when a normal target EV performs an operation specified by an operation command. The predetermined conditions are, for example, the end of the operation command (end of the operation specified by the operation command), the elevating speed being a predetermined value, the basket passing through a predetermined position between the floors, and the door being fully open or Although it is at least one of becoming fully closed, it is not restricted to this. The ideal timing acquisition unit 2 includes an ideal operation time DB 21 and an ideal timing calculation unit 22.

  The ideal operation time DB 21 stores ideal operation time. The ideal operation time is a time required for a normal elevator apparatus EV to perform a certain operation. The ideal operation time is set or measured in advance and stored for each specification of the elevator apparatus EV.

  Here, FIG. 3 is a diagram illustrating an example of an ideal operation time table (ideal operation time information) stored in the ideal operation time DB 21. As shown in FIG. 3, the ideal operation time DB 21 stores the operation of the elevator apparatus EV and the ideal operation time in association with each other. According to FIG. 3, for example, the ideal operation time until the cage rises from the first floor to the second floor is 5 seconds. This indicates that, when the elevator apparatus EV is normal, it takes 5 seconds for the basket to rise from the first floor to the second floor. The ideal operation time DB 21 stores such an ideal operation time table for each specification of the elevator apparatus EV.

  The ideal timing calculation unit 22 (hereinafter referred to as “calculation unit 22”) calculates an ideal timing. First, the calculation unit 22 receives from the control panel 201 the state of the target EV, the operation command transmitted from the control panel 201 to the target EV, and the start time when the target EV starts the operation specified by the operation command. To do.

  Next, the calculation unit 22 extracts the ideal operation time from the start time to the ideal timing from the ideal operation time DB 21 based on the state of the target EV and the operation command. And the calculation part 22 calculates the total time which totaled the extracted ideal operation time, and calculates the time after total time from a start time as an ideal timing.

  For example, when the predetermined condition is “end of operation command”, the state of the target EV is “stop on the first floor”, and the operation command is “move to the second floor”, the calculation unit 22 displays the ideal operation time table in FIG. 5 seconds (first floor → second floor) is extracted as the ideal operation time. In this case, the total time is 5 seconds. Then, the calculation unit 22 calculates 5 seconds after the start time as an ideal timing.

  Further, when the predetermined condition is “the door is fully open”, the state of the target EV is “stop on the first floor”, and the operation command is “move to the second floor”, the calculation unit 22 performs the ideal operation of FIG. From the time table, 5 seconds (first floor → second floor) and 3 seconds (door closed → door open) are extracted as ideal operation times. In this case, the total time is 8 seconds. Then, the calculation unit 22 calculates 8 seconds after the start time as an ideal timing.

  As described above, the calculation unit 22 can calculate one or a plurality of ideal timings corresponding to one or a plurality of conditions for one operation command.

  The failure diagnosis unit 3 (hereinafter referred to as “diagnosis unit 3”) diagnoses the presence or absence of a failure of the target EV based on the ideal timing and the actual timing. The actual timing is the time when the target EV performs the operation specified by the operation command and actually satisfies the above-described predetermined condition. For each condition, the ideal timing and the actual timing correspond one-to-one. The diagnosis unit 3 receives actual timing from the control panel 201.

  The diagnosis unit 3 diagnoses a failure of the target EV by calculating a time difference (shift in operation timing) between the ideal timing and the actual timing, and comparing the time difference with a predetermined threshold value. Specifically, the diagnosis unit 3 diagnoses that the target EV is out of order when the time difference is larger than the threshold value. The threshold value can be arbitrarily set, and may be the same or different for each condition for calculating the ideal timing. A diagnosis result by the diagnosis unit 3 is notified by a notification unit 7 described later.

  The failure information DB 4 stores failure information. The failure information is information in which the time difference between the ideal timing and the actual timing is associated with the failure portion of the elevator apparatus EV. The failure part here is, for example, at least one of equipment (motor, sensor, hoisting machine, etc.) constituting the elevator apparatus EV, a connection part between the equipments, and a specific part on the circuit of the equipment or the connection part. . The failure information is created based on, for example, past failure cases where the failure site has been found.

  Here, FIG. 4 is a diagram illustrating an example of a failure information table stored in the failure information DB 4. As shown in FIG. 4, the failure information table includes a plurality of failure information records, and each failure information includes a failure part, a failure content, and a plurality of time differences for each condition. For example, the failure information 1 indicates that when a contact failure occurs at the failure site A, the time difference of condition 1 occurs for 1 second and the time difference of condition 3 occurs for 3 seconds. The failure information DB 4 stores a plurality of such failure information tables for each specification. Note that the number of conditions included in the failure information table can be arbitrarily set.

  The failure site specifying unit 5 (hereinafter referred to as “specification unit 5”) acquires the diagnosis result from the diagnosis unit 3, and specifies the failure site when the target EV is diagnosed as a failure. Specifically, the specifying unit 5 acquires a time difference in each condition from the diagnosis unit 3 and refers to the failure information DB 4. Then, the identifying unit 5 extracts failure information having a matching time difference or a combination of time differences from the failure information DB 4 and identifies the failure part of the extracted failure information as the failure part of the target EV. The failure part extracted by the specifying unit 5 is notified by the notification unit 7.

  The circuit diagram acquisition unit 6 acquires a circuit diagram corresponding to the specification of the target EV acquired by the specification acquisition unit 1. The circuit diagram acquisition unit 6 includes a circuit diagram DB 61 and a circuit diagram extraction unit 62.

  The circuit diagram DB 61 stores a circuit diagram of each elevator apparatus EV included in the elevator facility 200 for each specification of the elevator apparatus EV. The circuit diagram includes a development connection diagram of each device constituting the elevator apparatus EV and a circuit diagram showing connection between the devices.

  The circuit diagram extraction unit 62 acquires the specification of the target EV from the specification extraction unit 12, and extracts the circuit diagram of the target EV with reference to the circuit diagram DB 61. The notification unit 7 notifies the circuit diagram of the target EV extracted by the circuit diagram extraction unit 62.

  The notification unit 7 notifies the diagnosis result of the target EV by the diagnosis unit 3, the failed part specified by the specification unit 5, and the circuit diagram of the target EV extracted by the circuit diagram extraction unit 62. In this case, the notification means that a diagnosis result or the like is output so that the maintenance staff of the target EV or the operator of the apparatus 100 can confirm the diagnosis result or the like.

  For example, the notification unit 7 may display a diagnosis result or the like on the display device 103 (described later) of the computer 100 ′ constituting the device 100. In addition, the notification unit 7 may transmit a diagnosis result or the like to the maintenance terminal 300 owned by a maintenance person who performs maintenance work on the target EV.
