  The present invention will be described with reference to the accompanying drawings. Duplicate descriptions will be simplified or omitted as appropriate. In each figure, the same reference numerals indicate the same or corresponding parts.

Embodiment 1 FIG.
FIG. 1 is a diagram illustrating an example of an elevator device according to the first embodiment. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down the hoistway 3. The counterweight 2 moves up and down the hoistway 3. The car 1 and the counterweight 2 are suspended from the hoistway 3 by the main rope 4.

  The main rope 4 is wound around a drive sheave 6 of a hoisting machine 5, for example. The hoisting machine 5 is controlled by the control device 7. That is, the movement and the stop of the car 1 are controlled by the control device 7. The monitoring device 8 is connected to the control device 7. The monitoring device 8 has a function of communicating with an external monitoring center. The monitoring device 8 has a maintenance function of the elevator device.

  FIG. 2 is a diagram illustrating an example of the car 1. FIG. 3 is a diagram showing a main part of the elevator device. The car 1 includes, for example, a car room 11, a door 12, a motor 13, an inspection light 14, an intrusion prevention belt 15, a detection sensor 16, and an operation panel 17. FIG. 2 shows the inside of the cab 11.

  An entrance is formed in the car room 11. The entrance of the car room 11 is formed by, for example, the pillar 21, the pillar 22, and the upper frame 23. The pillars 21 and 22 are arranged at a fixed interval. The upper frame 23 is disposed so as to straddle the columns 21 and 22. The door 12 opens and closes an entrance formed in the car room 11. The motor 13 generates a driving force for opening and closing the door 12. The motor 13 is controlled by the control device 7, for example.

  The inspection light 14 is an electric light used by an elevator maintenance worker when performing maintenance work in the hoistway 3. The check light 14 is provided outside the cab 11. FIG. 1 shows an example in which check lights 14 are provided above the cab 11 and below the cab 11. The position where the check light 14 is provided is not limited to the example shown in FIG. For example, the check light 14 may be provided only on the cab 11.

  The entrance prevention belt 15 is an example of a unit that prevents a user from entering the cab 11 when an elevator maintenance worker is performing maintenance work. The intrusion prevention belt 15 can be disposed at, for example, a first position and a second position. The first position is a position for preventing a user from entering the cab 11 from an entrance. The second position is a position that does not prevent the user from entering the cab 11.

  For example, the intrusion prevention belt 15 is pulled out of the pillar 22 when used. The intrusion prevention belt 15 is disposed at the first position by fixing the distal end portion to the column 21. FIG. 2 shows an example in which the intrusion prevention belt 15 is arranged at the first position. The intrusion prevention belt 15 is disposed at the second position by removing the leading end from the pillar 21 and storing it in the pillar 22.

  As another example, the intrusion prevention belt 15 is carried by elevator maintenance personnel. In such a case, the intrusion prevention belt 15 is attached between the columns 21 and 22 by a maintenance person when used. For example, the intrusion prevention belt 15 is disposed at the first position by attaching one end to the column 21 and attaching the other end to the column 22. The intrusion prevention belt 15 is disposed at the second position by being removed from the columns 21 and 22. In this example, the maintenance staff can use the intrusion prevention belt 15 at other sites.

  The detection sensor 16 is an example of a unit that detects a state in which the intrusion prevention belt 15 is disposed at the first position. In the following description, the above state is also referred to as an entry prevention state. For example, when the tip of the penetration prevention belt 15 is fixed to the column 21 by being hooked on a hook, the detection sensor 16 detects the entry prevention state when the tip of the penetration prevention belt 15 is hooked on the hook. . As another example, when each end of the intrusion prevention belt 15 is fixed to the columns 21 and 22 by a magnet, the detection sensor 16 detects the intrusion prevention state. The detection sensor 16 may detect the state in which the intrusion prevention belt 15 is disposed at the first position by another method.

  The operation panel 17 includes, for example, a display, a destination button, an open button of the door 12, and a close button of the door 12.

  Further, the elevator apparatus is provided with a plurality of switches operated during the maintenance work. The elevator device includes, for example, an inspection light switch 31, a mode switch 32, and a maintenance switch 33.

  The check light switch 31 is a switch for turning on and off the check light 14. The check light switch 31 is provided, for example, on the operation panel 17 of the car 1. For example, if the check light switch 31 is on, the check light 14 is turned on. If the check light switch 31 is off, the check light 14 is turned off. For example, a maintenance person of the elevator turns on the check light switch 31 when it is necessary to perform maintenance work in the hoistway 3. When the maintenance work in the hoistway 3 is completed, the maintenance staff turns off the check light switch 31. FIG. 3 shows an example in which the check light switch 31 is connected to the check light 14 via the control device 7. The check light switch 31 may be connected to the check light 14 without going through the control device 7.

  The mode switch 32 is a switch for switching the setting of the operation mode of the elevator. The mode switch 32 is provided in the control device 7, for example. For example, if the mode switch 32 is off, the operation mode is set to the automatic mode. The automatic mode is an operation mode in which the car 1 automatically responds to the registered call. If the mode switch 32 is on, the operation mode is set to the manual mode. The manual mode is an operation mode in which a maintenance person manually moves the car 1 from a dedicated device or the operation panel 17.

  The maintenance switch 33 is a switch for switching the setting of alerting to the outside. The maintenance switch 33 is provided, for example, in the control device 7. For example, if the maintenance switch 33 is turned off, an external alarm is permitted. For example, when the operation mode is set to the automatic mode, the maintenance switch 33 is basically off. When a specific abnormality is detected when the maintenance switch 33 is off, the monitoring device 8 issues a notification to the monitoring center.

  If the maintenance switch 33 is turned on, alarming to the outside is prohibited. For example, an elevator maintenance worker turns on the maintenance switch 33 when starting maintenance work. Therefore, while the maintenance person is performing the maintenance work, basically, the alert is not issued to the monitoring center. The maintenance worker turns off the maintenance switch 33 when the maintenance work is completed.

  Hereinafter, specific functions of the present elevator apparatus will be described with reference to FIG. FIG. 4 is a flowchart illustrating an operation example of the control device 7. As shown in FIG. 3, the control device 7 includes, for example, a determination unit 41 and a forced light-off unit 42.

  The determination unit 41 determines whether the check light switch 31 is on (S101). If the check light switch 31 is off (No in S101), the check light 14 is turned off (S102). If the check light switch 31 is on (Yes in S101), the check light 14 is turned on (S103).

  When the check lamp 14 is on, the determination unit 41 determines whether the maintenance switch 33 is off (S104). If the maintenance switch 33 is on (No in S104), the determination unit 41 determines whether the mode switch 32 is off (S105). If both the maintenance switch 33 and the mode switch 32 are ON (No in S105), the control device 7 returns to the processing in S101.

  If the determination is Yes in S104 or S105, the determination unit 41 determines whether the detection sensor 16 has detected the approach prevention state (S106). If the detection sensor 16 has detected the entry prevention state (Yes in S106), the control device 7 returns to the processing in S101.

  On the other hand, if the detection sensor 16 has not detected the entry prevention state (No in S106), the determination unit 41 determines that the forced light-off condition has been satisfied (S107). That is, when the detection sensor 16 does not detect the entry prevention state and at least one of the maintenance switch 33 and the mode switch 32 is off, the determination unit 41 determines in S107 that the forced light-off condition is satisfied.

  If the forced light-off condition is satisfied in S107, that is, if the forced light-off condition is satisfied while the check light switch 31 is on, the forced light-out unit 42 starts a process for forcibly turning off the check light 14. For example, the forced light-off unit 42 determines whether or not a fixed time has elapsed since the forced light-off condition was satisfied (S108). The fixed time may be any time. For example, the fixed time is 10 minutes. The fixed time may be a very short time. When a predetermined time has elapsed after the forced light-off condition is satisfied (Yes in S108), the forced light-out unit 42 turns off the check lamp 14 (S109). Further, the check light switch 31 is turned off (S110).

  In the example shown in the present embodiment, when the forcible light-off condition is satisfied in S107, the check lamp 14 is automatically turned off. For this reason, forgetting to turn off the check lamp 14 after the maintenance work can be prevented. When a maintenance worker performs maintenance work in the hoistway 3, the intrusion prevention belt 15 is disposed at the first position in order to prevent a user from accidentally entering the cab 11. In the example shown in the present embodiment, if the intrusion prevention belt 15 is arranged at the first position, the forced light-off condition is not satisfied. Therefore, it is possible to prevent the check lamp 14 from being turned off while the maintenance staff is performing the maintenance work in the hoistway 3.

  In the above example, an example has been described in which both the maintenance switch 33 and the mode switch 32 are used to determine whether the forced light-off condition is satisfied. The mode switch 32 does not have to be used to determine whether the forced light-off condition is satisfied. In such a case, the process of S105 is not performed in the operation flow illustrated in FIG. If the maintenance switch 33 is on in S104, the control device 7 returns to the process of S101. In addition, when the detection sensor 16 does not detect the entry prevention state and the maintenance switch 33 is off, the determination unit 41 determines in S107 that the forced light-off condition is satisfied.

  As another example, the maintenance switch 33 may not be used to determine whether or not the forced light-off condition is satisfied. In such a case, the process of S104 is not performed in the operation flow illustrated in FIG. If the check lamp 14 is turned on (S103), the determination unit 41 determines whether the mode switch 32 is off (S105). In addition, when the detection sensor 16 does not detect the entry prevention state and the mode switch 32 is off, the determination unit 41 determines in S107 that the forced light-off condition is satisfied.

  In the above example, an example has been described in which the detection sensor 16 is used to determine whether the forced light-off condition is satisfied. The photoelectric sensor 18 may be used instead of using the detection sensor 16 in determining whether or not the forced light-off condition is satisfied. The photoelectric sensor 18 is provided in the car 1. The photoelectric sensor 18 is a sensor for preventing foreign matter from being drawn into the door 12 when the door 12 is opened. The photoelectric sensor 18 emits light that travels upward or downward through the doorway, and the light is blocked to detect foreign matter.

  FIG. 5 is a diagram illustrating another example of the car 1. FIG. 5 shows the inside of the cab 11. The photoelectric sensor 18 includes, for example, a light emitter 34 and a light receiver 35. The light emitter 34 is provided on the pillar 21. The light emitter 34 emits light obliquely upward. Light from the light emitter 34 travels through the entrance obliquely upward. The light receiver 35 is provided on the upper frame 23. The light receiver 35 is arranged at a position where light from the light emitter 34 can be received.

  In the example illustrated in FIG. 5, when the intrusion prevention belt 15 is disposed at the first position, light from the light emitter 34 is blocked by the intrusion prevention belt 15. The light receiver 35 cannot receive light from the light emitter 34. Therefore, when the intrusion prevention belt 15 is disposed at the first position, the photoelectric sensor 18 detects a foreign substance.

  FIG. 6 is a flowchart illustrating another operation example of the control device 7. The processing shown in S201 to S205 in FIG. 6 is the same as the processing shown in S101 to S105 in FIG. If the determination unit 41 determines Yes in S204 or S205, it determines whether the photoelectric sensor 18 has detected a foreign substance (S206). If the photoelectric sensor 18 has detected a foreign substance (Yes in S206), the control device 7 returns to the processing in S201.

  On the other hand, if the photoelectric sensor 18 has not detected a foreign substance (No in S206), the determination unit 41 determines that the forced light-off condition has been satisfied (S207). That is, when no foreign matter is detected by the photoelectric sensor 18 and at least one of the maintenance switch 33 and the mode switch 32 is off, the determination unit 41 determines in S207 that the forced light-off condition is satisfied.

  The processing shown in S208 to S210 in FIG. 6 is the same as the processing shown in S108 to S110 in FIG.

  Even in the example shown in FIG. 6, it is possible to prevent forgetting to turn off the check light 14 after the maintenance work. In addition, it is possible to prevent the check lamp 14 from going out while the maintenance staff is performing maintenance work in the hoistway 3.

  In the example illustrated in FIG. 6, an example has been described in which both the maintenance switch 33 and the mode switch 32 are used to determine whether the forced light-off condition is satisfied. The mode switch 32 does not have to be used to determine whether the forced light-off condition is satisfied. In such a case, the process of S205 is not performed in the operation flow shown in FIG. If the maintenance switch 33 is on in S204, the control device 7 returns to the process of S201. In addition, when no foreign matter is detected by the photoelectric sensor 18 and the maintenance switch 33 is off, the determination unit 41 determines in S207 that the forced light-off condition is satisfied.

  As another example, the maintenance switch 33 may not be used to determine whether or not the forced light-off condition is satisfied. In such a case, the process of S204 is not performed in the operation flow illustrated in FIG. If the check lamp 14 is turned on (S203), the determination unit 41 determines whether the mode switch 32 is off (S205). In addition, when no foreign matter is detected by the photoelectric sensor 18 and the mode switch 32 is off, the determination unit 41 determines in S207 that the forced light-off condition is satisfied.

  In the present embodiment, the components indicated by reference numerals 41 to 42 indicate the functions of the control device 7. FIG. 7 is a diagram illustrating an example of hardware resources of the control device 7. The control device 7 includes a processing circuit 50 including, for example, a processor 51 and a memory 52 as hardware resources. The control device 7 executes the programs stored in the memory 52 by the processor 51, thereby realizing the functions of the components indicated by reference numerals 41 to 42.

  FIG. 8 is a diagram illustrating another example of the hardware resources of the control device 7. In the example illustrated in FIG. 8, the control device 7 includes a processing circuit 50 including, for example, a processor 51, a memory 52, and dedicated hardware 53. FIG. 8 shows an example in which some of the functions of the control device 7 are implemented by dedicated hardware 53. All of the functions of the control device 7 may be realized by the dedicated hardware 53.
