The predetermined operation described above includes, for example, an operation of turning on the maintenance switch 11c while pressing the open button 11a, and the maintenance operation traveling unit 10g is stopped when the car 2 is stopped during the landing maintenance operation mode, for example. The car 2 is moved up and down at a lower speed than usual in conjunction with the pressing of the up landing call buttons 14d and 15d and the down landing call buttons 15e and 16e.

  In addition, the maintenance operation traveling unit 10g can get on even if the landing stop call buttons 15e and 16e are pressed when the stop of the operation of the car 2 by the car top stop switch 13 which is input during the landing maintenance operation mode is released. Even when the car 2 is lifted at a lower speed than usual, and the stop of the operation of the car 2 by the pit stop switch 9 that is turned on during the hall maintenance operation mode is released, the lift hall call buttons 14d and 15d are pressed. The car 2 is lowered at a lower speed than usual.

  Specifically, the control device 10 includes a lift distance measuring unit 10a that measures the lift distance from the landing of the car 2 when the landing maintenance operation setting unit 10h sets the landing maintenance operation mode, and the lift distance measurement. The car position detection unit 10f that detects the floor position of the car 2 based on the output signal of the unit 10a and detects the driving direction based on the output signal of the maintenance operation traveling unit 10g, and the lift distance measurement unit 10a A display control unit 10m that displays the measured lift distance on the position indicators 14c to 16c and a travel control unit 10k that controls the travel of the car 2 according to the output signal of the maintenance operation travel unit 10g are provided. .

  The lift distance measuring unit 10a is attached to, for example, a motor 5 of a hoisting machine, and generates and adds a subtraction pulse of the car 2 from an output signal of the encoder 8 that generates a pulse corresponding to the number of rotations of the motor 5. Thus, it is composed of a lift distance calculation unit (not shown) that calculates the lift distance from the platform of the car 2. The display control unit 10m lights up the ascending direction lights 14a to 16a or the descending direction lights 14b to 16b in accordance with the driving direction of the car 2, in addition to the lifting distance from the landing of the car 2, and the operation mode of the elevator Is set to the normal mode, the floor positions of the car 2 detected by the car position detector 10f are displayed on the indicators 14c to 16c.

  The control device 10 includes a stop switch operation detection unit 10b that detects operations of the car stop switch 13, the pit stop switch 9, and the car stop switch, an open button 11a, a close button 11b, and a car call button 11d of the operation panel 11.

A button press detection unit 10e.

  When the maintenance operation traveling unit 10g receives the input signal of the maintenance switch 11c from the operation panel switch operation detection unit 10c, the maintenance operation traveling unit 10g receives the pressing signals of the up and down buttons of the operation panel 11 from the operation panel switch operation detection unit 10c. Thus, a low speed raising / lowering signal for raising and lowering the car 2 at a lower speed than normal is output to the traveling control unit 10k in response to the pressing signals of these up and down buttons.

  When the low speed raising / lowering signal is input from the maintenance operation traveling unit 10g, the traveling control unit 10k outputs a car door door closing control signal for closing the car door to the door control device on the car 2. The door control device closes the car door when the car door door closing control signal is input from the traveling control unit 10k. At this time, when the landing door is engaged with the car door, a landing door closing control signal for closing the landing door is input, and the landing door is also closed in conjunction with the car door. Then, the traveling control unit 10k outputs a low speed raising / lowering signal to the motor 5, and the motor 5 is rotated forward at a low speed in accordance with the inputted low speed raising / lowering signal, so that the car 2 is raised and lowered at a lower speed than usual. I have to.

  Next, as an apparatus installed on the car door by a technical worker, for example, an operation of performing a maintenance check on a car door switch provided on the upper part of the car door of the car 2 will be described. In addition, since the maintenance inspection of the equipment installed in the car door is often performed on the intermediate floor where the elevator 2 is relatively easy to move up and down, in the following description, the technical worker is the intermediate floor 2 Details on working on the floor.

  When the technical worker performs an operation of turning on the maintenance switch 11c while pressing the opening button 11a of the operation panel 11 in the car 2, the maintenance operation traveling unit 10g is opened from the operation panel switch operation detection unit 10c by the opening button 11a. By receiving the detection signal of the maintenance switch 11c at the same time, the hall maintenance operation setting unit 10h sets the elevator operation mode to the hall maintenance operation mode.

  Then, the technical worker gets off to the second floor landing where the car 2 is stopped, and presses the lower landing call button 15e of the display device 15 installed on the second floor landing. At this time, the hall call button press detection unit 10e detects the press signal of the descending hall call button 15e, and outputs this press signal to the maintenance operation traveling unit 10g.

  Next, the maintenance driving travel unit 10g receives the landing position indicated by the pressing signal of the descending landing call button 15e input from the landing call button press detection unit 10e and the floor of the car 2 input from the car position detection unit 10f. When the floor position indicated by the floor signal coincides, a low speed lowering signal for lowering the car 2 at a lower speed than normal is output to the traveling control unit 10k.

  The traveling control unit 10k outputs a car door door closing control signal to the door control device on the car 2 when the low speed lowering signal is input from the maintenance driving traveling unit 10g. The door control device closes the car door when the car door door closing control signal is input from the traveling control unit 10k. At this time, if the landing door is engaged with the car door, a landing door door closing control signal is input, and the landing door is also closed in conjunction with the car door. Then, the traveling control unit 10k outputs a low speed lowering signal to the motor 5, and the motor 5 rotates backward at a low speed according to the input low speed lowering signal, thereby lowering the car 2 at a lower speed than usual.

  At this time, the lift distance measuring unit 10a outputs a lift distance signal indicating the measured lift distance to the car position detecting unit 10f, and the maintenance operation traveling unit 10g sets the operation mode of the elevator to the landing maintenance operation mode. A hall maintenance operation setting signal and a driving direction signal indicating that the driving direction of the car 2 is the downward direction are output to the car position detection unit 10f. When the car position detection unit 10f receives the landing maintenance operation setting signal from the maintenance operation traveling unit 10g, the display position control unit displays the elevation distance signal input from the elevation distance measurement unit 10a and the operation direction signal input from the maintenance operation traveling unit 10g. Output to 10m.

  When the display controller 10m inputs the lift distance signal and the driving direction signal from the car position detector 10f, the display controller 10m lights the descending direction light 15b of the display device 15 on the second floor landing and also displays the lift distance on the position indicator 15c. Display. Here, the display of the lifting distance on the position indicator 15c is, for example, when the height of the car 2 is the same as the floor of the second floor hall, that is, the car 2 is landed on the second floor hall. It becomes 0 when the car is moving, and when the car 2 moves away from the floor of the second floor hall, the number of predetermined distance units increases to 1, 2, 3, 4,. When approaching the floor, it decreases to 4, 3, 2, 1, 0.

  The technical worker who has pressed the lower landing call button 15e determines that the lift distance of the car 2 has reached the target distance by checking the display on the position indicator 15c, and presses the lower landing call button 15e. When the operation is stopped, the maintenance operation traveling unit 10g stops outputting the low speed lowering signal to the traveling control unit 10k, so that the traveling control unit 10k stops outputting the low speed lowering signal to the motor 5, and the car Stop descent of 2. The technical worker opens the landing door and inspects the car door switch at the top of the car door.

  Next, after finishing the inspection of the car door switch, the technical worker closes the landing door and then presses the rising landing call button 15d of the display device 15. At this time, the hall call button press detection unit 10e detects the press signal of the ascending landing call button 15e, and outputs this press signal to the maintenance operation traveling unit 10g. When the maintenance operation traveling unit 10g receives a pressing signal from the hall call button pressing detection unit 10e, the maintenance driving traveling unit 10g outputs a low speed increase signal to the traveling control unit 10k to raise the car 2 at a lower speed than usual.

  The travel control unit 10k outputs a low speed increase signal to the motor 5 when the low speed increase signal is input from the maintenance operation travel unit 10g, and the motor 5 rotates forward at a low speed according to the input low speed increase signal. Raise the car 2 at a lower speed than usual. The technical worker who has pressed the lift hall call button 15e continues to press the lift hall call button 15d until the display on the position indicator 15c becomes zero.

  When the display on the position indicator 15c becomes 0, the height of the floor of the car 2 becomes the same as the height of the floor of the hall, so that the technical worker can get into the car 2. As a result, the technical worker operates the operation panel 11 to cancel the setting of the landing maintenance operation mode, and the work for performing the maintenance inspection of the car door switch is completed.

  When a technical worker performs maintenance and inspection of the equipment provided in the lower part of the car 2, the lift hall call button 15e is pressed while confirming the display on the position indicator 15c, and the work is easily performed. After raising the car 2 at a low speed, the equipment is inspected. Then, after the technical worker completes the inspection of the device, the user presses the lower landing call button 15e while confirming the display on the position indicator 15c, and lowers the car 2 at a low speed to land on the landing. good.

  Further, when a technical worker performs maintenance and inspection of the equipment provided on the upper portion of the car 2, while checking the display of the position indicator 15c, as in the above-described maintenance and inspection of the car door switch. After pressing down the descent landing call button 15e and lowering the car 2 at a low speed to the boarding position on the car 2, that is, boarding the car 2 and checking the equipment. . Then, after the technical worker completes the inspection of the equipment, the elevator hall call button 15d is pressed while confirming the display of the position indicator 15c, and the car 2 is raised at a low speed to land on the hall. good.

  On the other hand, when a technical worker performs maintenance and inspection of equipment installed on the ceiling of the hoistway, work is performed on the third floor, which is the top floor. Since there is the descending hall call button 16e, the technical worker boardes the car 2 and checks the equipment in the same manner as in the case of carrying out the maintenance check of the equipment provided on the upper part of the car 2 described above. be able to.

  In this case, after the technical worker finishes the inspection of the equipment, the car top stop switch 13 is first turned on to stop the operation of the car 2 in an emergency. Next, when the technical worker opens the landing door on the third floor and gets off from the platform 2 to the platform on the third floor, the maintenance stop travel section is released by releasing the on-car stop switch 13 and closing the platform door. 10g receives a release signal from the stop switch operation detection unit 10b to release the on-the-car stop switch 13 during the hall maintenance operation mode.

  Then, the engineer presses the lower landing call button 16e, so that the maintenance operation traveling unit 10g inputs the pressing signal of the lower landing call button 16e from the landing call button press detection unit 10e, and thus travels at a low speed increase signal. It outputs to the control part 10k. The travel control unit 10k outputs a low speed increase signal to the motor 5 when the low speed increase signal is input from the maintenance operation travel unit 10g, and the motor 5 rotates forward at a low speed according to the input low speed increase signal. The car 2 can be raised at a lower speed than usual. Thus, the technical worker may press the descending hall call button 16e while confirming the display on the position indicator 16c, raise the car 2 at a low speed, and land on the third floor hall.

  Similarly, when a technical worker performs maintenance and inspection of the equipment installed in the pit section, the work is performed on the first floor, which is the lowest floor, but the display device 14 on the first floor is elevated. Since there is the hall call button 14d, the technical worker can inspect the equipment in the same manner as in the case of inspecting the equipment provided in the lower part of the car 2 described above.

  In this case, after the technical worker completes the inspection of the equipment, the pit stop switch 9 is first turned on to stop the operation of the car 2 in an emergency. Next, when the technical worker opens the landing door on the first floor and moves from the pit section to the first floor landing, the maintenance operation traveling section 10g is released by releasing the pit stop switch 9 and closing the landing door. Then, a release signal for canceling the input of the pit stop switch 9 is received from the stop switch operation detection unit 10b during the hall maintenance operation mode.

  When the technical worker presses the rising hall call button 14d, the maintenance operation traveling unit 10g inputs the pressing signal of the rising hall call button 14d from the landing call button press detecting unit 10e, and thus travels at a low speed lowering signal. It outputs to the control part 10k. When the low speed decrease signal is input from the maintenance operation travel unit 10g, the travel control unit 10k outputs a low speed decrease signal to the motor 5, and the motor 5 reversely rotates at a low speed according to the input low speed decrease signal. The car 2 can be lowered at a lower speed than usual. Thus, the technical worker may press the lift hall call button 14d while confirming the display on the position indicator 14c, and lower the car 2 at a low speed to land on the first floor hall.

  Next, the processing operation of the control device according to the present embodiment will be described in detail based on the flowchart of FIG.

  In this embodiment, the operation panel switch operation detection unit 10c confirms whether a predetermined operation on the operation panel 11, that is, an operation of turning on the maintenance switch 11c while pressing the open button 11a has been performed (step (hereinafter referred to as “step (hereinafter referred to as“ step ”)). , S) 1). At this time, when the operation panel switch operation detection unit 10c confirms that the operation of turning on the maintenance switch 11c is not performed while pressing the open button 11a (S1 / NO), the processing operation of the procedure S1 is repeated. .

  On the other hand, when the operation panel switch operation detection unit 10c confirms that the operation of turning on the maintenance switch 11c is performed while pressing the open button 11a in step S1 (S1 / YES), the landing of the maintenance operation traveling unit 10g The maintenance operation setting unit 10h sets the elevator operation mode to the landing maintenance operation mode, and performs the processing operation of the landing maintenance operation described later (S2).

  When the processing operation of the landing maintenance operation is completed in step S2, the stop switch operation detection unit 10b checks whether at least one of the car stop switch 13 and the pit stop switch 9 is turned on (S3). At this time, when the stop switch operation detection unit 10b confirms that neither the car stop switch 13 nor the pit stop switch is turned on (S3 / NO), the operation panel switch operation detection unit 10c turns on the maintenance switch 11c. It is confirmed whether or not is released (S14).

  In step S3, when the stop switch operation detection unit 10b confirms that at least one of the car stop switch 13 and the pit stop switch is turned on (S3 / YES), the landing maintenance operation setting unit 10h is set in step S2. The landing maintenance operation mode is interrupted (S4), and the maintenance operation traveling unit 10g sets the operation mode of the elevator to the maintenance operation mode, and performs the processing operation of the maintenance operation that has been conventionally performed (S5).

  Here, the maintenance operation performed in step S5 means that, for example, when an engineer turns on only the maintenance switch 11c in the car 2, the operation mode of the elevator is set to the maintenance operation mode.
