The functions of the maintenance terminal 20 will be described in detail below with reference to FIGS. 3 and 4 as well. FIG. 3 is a flowchart showing an operation example of the maintenance terminal 20. As shown in FIG.

As mentioned above, the server 10 manages multiple elevators. The server 10 stores the car chart of each elevator managed. The car chart contains various information about elevator maintenance. For example, the car chart includes identification information for identifying an elevator and inspection information for specifying the inspection date and inspection details of the elevator. The identification information may be represented by a combination of the building number and the machine number. The inspection information includes the work record of past inspections and the work plan of future inspections. The work plan includes, for example, the date and time of inspection, the name of the maintenance engineer in charge, and the content of work.

The maintenance terminal 20 determines whether or not it is connected to the server 10 (S101). A maintenance worker connects the maintenance terminal 20 to the server 10 in, for example, an office before going to the elevator site. As a result, a determination of Yes is made in S101. When the maintenance person connects the maintenance terminal 20 to the server 10, the maintenance person downloads from the server 10 the car chart of the elevator that he or she is in charge of. Maintenance personnel are in charge of more than one elevator. Therefore, a plurality of car charts are stored in the storage unit 23 of the maintenance terminal 20 (S102).

FIG. 4 is a flow chart showing another operation example of the maintenance terminal 20. As shown in FIG. FIG. 4 shows the operation flow of the maintenance terminal 20 when maintenance personnel start inspecting the elevator. As described above, maintenance personnel bring the maintenance terminal 20 to the site when inspecting the elevator. At this time, the storage unit 23 of the maintenance terminal 20 stores a plurality of car charts.

The maintenance terminal 20 determines whether or not it is connected to the control panel 6 of the elevator (S201). FIG. 2 shows an example in which the communication unit 24 is connected to the control panel 6 via the monitoring device 8. As shown in FIG. The communication unit 24 may be connected to the monitoring device 8 by wire or wirelessly. When the maintenance worker arrives at the elevator site to be inspected, he or she first connects the maintenance terminal 20 to the control panel 6 . As a result, a determination of Yes is made in S201.

The detection unit 25 detects that the maintenance terminal 20 is connected to the control panel 6 (S202). When the connection with the control panel 6 is detected by the detection unit 25, the acquisition unit 26 acquires identification information for identifying the elevator from the control panel 6 (S203).

When the detection unit 25 detects the connection with the control panel 6 in S202, the specifying unit 27 specifies the car chart of the elevator having the control board 6 from among the car charts stored in the storage unit 23. (S204). As an example, the identification unit 27 identifies the car chart based on the identification information acquired by the acquisition unit 26 in S203. For example, the identification unit 27 extracts from the storage unit 23 the car record including the same identification information as the identification information that the acquisition unit 26 acquired from the control panel 6 in S204.

As another example, when the maintenance worker connects the maintenance terminal 20 to the control panel 6 , the elevator identification information is input from the input device 21 . The identification unit 27 identifies the car chart based on the identification information input from the input device 21 . For example, the identification unit 27 extracts from the storage unit 23 the car record containing the same identification information as the identification information input from the input device 21 .

As another example, when the maintenance worker connects the maintenance terminal 20 to the control panel 6 , he inputs the building number from the input device 21 . In such a case, the identification unit 27 extracts from the storage unit 23 the car record whose identification information includes the building number input from the input device 21 . At this time, if a plurality of car charts are extracted by the identification unit 27, the maintenance staff selects one car chart from among them using the input device 21. FIG. The identification unit 27 identifies the selected car chart as the car chart of the elevator.

Next, the determination unit 28 determines whether or not the work to be performed by the maintenance staff in the elevator from now on includes the first work to be performed on the car 1 (S205). The determination unit 28 makes determination in S205 based on the car chart identified by the identification unit 27 . The first task is preset. For example, the determining unit 28 identifies the work content scheduled for the day in the elevator from the car chart identified by the identifying unit 27 . If even one of the specified work contents corresponds to the first work, the determination unit 28 determines Yes in S205.

Further, the determination unit 28 determines whether or not the second work to be performed in the pit of the hoistway 3 is included in the work to be performed by the maintenance staff in the elevator (S206). The determination unit 28 makes determination in S206 based on the car chart identified by the identification unit 27 . The second task is preset. For example, if even one of the specified work contents corresponds to the second work, the determination unit 28 determines Yes in S206.

If it is determined as Yes in at least one of S205 or S206, the notification control unit 29 calls attention from the notification device 22 (S207). For example, the notification control unit 29 may say, "In today's inspection, work on the car or work in the pit is scheduled. When work is to be done on the car or in the pit, notify other people to that effect. When you are working in another place, there is a possibility that other people are working on the car or in the pit.If you cannot decide by yourself during the work, ask your superior Please consult with us." is played from the speaker or displayed on the display.

Note that if both S205 and S206 are determined to be No, the attention is not called in S207. In such a case, the process ends.

In the example shown in the present embodiment, when the inspection of the elevator is started, if work on the car 1 is scheduled in the inspection, an appropriate notification to call maintenance personnel's attention is given. done. That is, the maintenance staff can inspect the elevator after recognizing that the work on the car 1 is scheduled. When starting inspection, the maintenance worker can know that there is a possibility that another maintenance worker may be on top of the car 1 even if he is not on top of the car 1 .

Similarly, in the example shown in the present embodiment, when the inspection of the elevator is started, if the work in the pit of the hoistway 3 is scheduled in the inspection, a warning is displayed to the maintenance personnel. Appropriate notification is provided. That is, the maintenance staff can inspect the elevator after recognizing that the work in the pit is scheduled. For example, when starting inspection, a maintenance worker can know that there is a possibility that another maintenance worker may be in the pit even if he is not in the pit.

In this embodiment, a preferred example in which both the determination of S205 and the determination of S206 are performed has been described. A certain effect can be expected even if only one of the determination of S205 and the determination of S206 is performed.
