DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a detailed description will be given with reference to the drawings. Duplicate descriptions will be appropriately simplified or omitted. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0010] Embodiment 1 FIG. 1 is a diagram showing an example of an elevator. The elevator includes a car 1 and a counterweight 2. The car 1 moves up and down in a hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The hoistway 3 is a space extending vertically in a building. The car 1 and the counterweight 2 are suspended in the hoistway 3 by a rope 4. FIG. 1 shows an example of an elevator device using a 1:1 roping system.

[0011] The rope 4 is wound around a hoisting machine 5. The car 1 is driven by the hoisting machine 5. A control panel 6 controls the hoisting machine 5. That is, the movement of the car 1 is controlled by the control panel 6. FIG. 1 shows an example in which the hoisting machine 5 and the control panel 6 are provided in a machine room 7 above the hoistway 3. The hoisting machine 5 and the control panel 6 may be provided in the hoistway 3. The hoisting machine 5 may be provided at the top of the hoistway 3 or in a pit of the hoistway 3.

[0012] The monitoring device 8 is connected to the control panel 6. The monitoring device 8 communicates with external devices via a network 9. The external devices include a server 10. As an example, the server 10 is provided in a remote information center that manages the elevator. The server 10 manages a large number of elevators.

[0013] The maintenance terminal 20 is a terminal carried by an elevator maintenance worker. The maintenance worker brings the maintenance terminal 20 to the site when inspecting the elevator. The maintenance worker inspects the elevator using the maintenance terminal 20. For example, the maintenance terminal 20 has a function of acquiring data required for the inspection from the control panel 6. The maintenance terminal 20 has a function of sending commands required for the inspection to the control panel 6. The maintenance terminal 20 is, for example, a smartphone. The maintenance terminal 20 may be a tablet-type terminal. The maintenance terminal 20 may be a dedicated terminal designed for elevator inspection.

[0014] 2 is a diagram for explaining the function of the maintenance terminal 20. The maintenance terminal 20 includes an input device 21 and an alarm 22. A maintenance worker inputs information from the input device 21. The maintenance terminal 20 includes a display as the alarm 22. The maintenance terminal 20 may include a speaker as the alarm 22. The maintenance terminal 20 may include both a display and a speaker as the alarm 22. The input device 21 and the alarm 22 may be an integrated device of a touch panel type. The input device 21 may be a keyboard or a mouse.

[0015] The maintenance terminal 20 further includes a storage unit 23, a communication unit 24, a detection unit 25, an acquisition unit 26, an identification unit 27, a determination unit 28, and an alarm control unit 29. The communication unit 24 is responsible for the communication function of the maintenance terminal 20. The alarm control unit 29 controls the alarm 22. The functions of the maintenance terminal 20 will be described in detail below with reference to Figs. 3 and 4. Fig. 3 is a flowchart showing an example of the operation of the maintenance terminal 20.

[0016] As described above, the server 10 manages a large number of elevators. The server 10 stores the elevator number chart for each elevator it manages. The elevator number chart includes various information related to elevator maintenance. For example, the elevator number chart includes identification information for identifying the elevator and inspection information for specifying the inspection date and inspection content of the elevator. The identification information may be expressed as a combination of a building number and an elevator number. The inspection information includes work results related to past inspections and work plans for future inspections. The work plan includes, for example, the inspection date and time, the name of the maintenance technician in charge, and the work content.

[0017] The maintenance terminal 20 determines whether it is connected to the server 10 (S101). Before going to the elevator site, the maintenance worker connects the maintenance terminal 20 to the server 10, for example, in the office. This results in a Yes determination in S101. When the maintenance worker connects the maintenance terminal 20 to the server 10, he downloads the elevator number chart for the elevator he is in charge of from the server 10. A maintenance worker is in charge of more than one elevator. For this reason, multiple elevator number charts are stored in the memory unit 23 of the maintenance terminal 20 (S102).

[0018] Fig. 4 is a flowchart showing another operation example of the maintenance terminal 20. Fig. 4 shows the operation flow of the maintenance terminal 20 when a maintenance worker starts an elevator inspection. As described above, the maintenance worker brings the maintenance terminal 20 to the site when inspecting the elevator. At this time, a plurality of elevator charts are stored in the memory unit 23 of the maintenance terminal 20.

[0019] In the maintenance terminal 20, it is determined whether or not it is connected to the elevator control panel 6 (S201). Fig. 2 shows an example in which the communication unit 24 is connected to the control panel 6 via the monitoring device 8. The communication unit 24 may be connected to the monitoring device 8 by wire or wirelessly. When the maintenance worker arrives at the site of the elevator to be inspected, he first connects the maintenance terminal 20 to the control panel 6. As a result, the result of S201 is determined as Yes.

[0020] The detection unit 25 detects that the maintenance terminal 20 is connected to the control panel 6 (S202). When the detection unit 25 detects the connection with the control panel 6, the acquisition unit 26 acquires identification information for identifying the elevator from the control panel 6 (S203).

[0021] When the detection unit 25 detects a connection to the control panel 6 in S202, the identification unit 27 identifies the elevator car chart of the elevator having the control panel 6 from among the multiple elevator car charts stored in the storage unit 23 (S204). As an example, the identification unit 27 identifies the elevator 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 elevator car chart including the same identification information as the identification information acquired from the control panel 6 by the acquisition unit 26 in S204.

[0022] As another example, when a maintenance worker connects the maintenance terminal 20 to the control panel 6, the maintenance worker inputs the elevator identification information from the input device 21. The identification unit 27 identifies the elevator 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 elevator chart that includes the same identification information as the identification information input from the input device 21.

[0023] As another example, when a maintenance worker connects the maintenance terminal 20 to the control panel 6, the maintenance worker inputs a building number from the input device 21. In such a case, the identification unit 27 extracts from the storage unit 23 a unit number chart whose identification information includes the building number input from the input device 21. At this time, if multiple unit number charts are extracted by the identification unit 27, the maintenance worker selects one unit number chart from among them using the input device 21. The identification unit 27 identifies the selected unit number chart as the unit number chart for the elevator in question.

[0024] Next, the determination unit 28 determines whether or not the work to be performed by the maintenance worker in the elevator includes a first work to be performed on the car 1 (S205). The determination unit 28 makes the determination in S205 based on the car chart identified by the identification unit 27. The first work is set in advance. For example, the determination unit 28 identifies the work content scheduled for the elevator on that day from the car chart identified by the identification unit 27. If any one of the identified work contents corresponds to the first work, the determination unit 28 determines Yes in S205.

[0025] The determination unit 28 also determines whether or not the work to be performed by the maintenance worker in the elevator includes a second work to be performed in the pit of the elevator shaft 3 (S206). The determination unit 28 makes the determination in S206 based on the elevator chart identified by the identification unit 27. The second work is set in advance. For example, the determination unit 28 determines Yes in S206 if any one of the identified work contents corresponds to the second work.

[0026] If at least one of S205 and S206 is judged as Yes, the notification control unit 29 issues a warning from the alarm 22 (S207). For example, the notification control unit 29 issues a message from the speaker or displays on the display such as "Today's inspection is scheduled to include work on the car or in the pit. If you are going to work on the car or in the pit, please inform others before starting the work. Even if you are going to work in another place, there is a possibility that others are working on the car or in the pit. If you are unable to make a decision by yourself while working, please consult your supervisor."

[0027] If the determination is No in both S205 and S206, no warning is issued in S207, and the process ends in this case.

[0028] In the example shown in this embodiment, when an elevator inspection is started, if work is scheduled to be done on car 1 during the inspection, an appropriate notification is issued to alert the maintenance staff. That is, the maintenance staff can inspect the elevator after recognizing that work is scheduled to be done on car 1. When starting the inspection, the maintenance staff can understand that even if they are not on car 1, there is a possibility that another maintenance staff member is on car 1.

[0029] Similarly, in the example shown in this embodiment, when an elevator inspection is started, if work is scheduled to be done in the pit of the hoistway 3 during the inspection, an appropriate notification is issued to alert the maintenance personnel. That is, the maintenance personnel can inspect the elevator after recognizing that work is scheduled to be done in the pit. For example, the maintenance personnel can know when starting the inspection that even if they are not in the pit, there is a possibility that another maintenance personnel is in the pit.

[0030] In the present embodiment, a preferred example has been described in which the determinations in both S205 and S206 are performed. Even if only one of the determinations in S205 or S206 is performed, a certain degree of effect can be expected.

[0031] 5 is a diagram showing an example of hardware resources of the maintenance terminal 20. The maintenance terminal 20 includes, as hardware resources, a processing circuit 30 including a processor 31 and a memory 32. The processing circuit 30 may include a plurality of processors 31. The processing circuit 30 may include a plurality of memories 32.

[0032] In this embodiment, each unit indicated by the reference numerals 23 to 29 indicates a function possessed by the maintenance terminal 20. The functions of each unit indicated by the reference numerals 24 to 29 can be realized by software written as a program, firmware, or a combination of software and firmware. The program is stored in the memory 32. The maintenance terminal 20 realizes the functions of each unit indicated by the reference numerals 24 to 29 by executing the program stored in the memory 32 by the processor 31. The function of the storage unit 23 is realized by the memory 32. A semiconductor memory or the like can be adopted as the memory 32.
