Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a schematic diagram showing the overall configuration of an elevator apparatus according to an embodiment of the present invention.
In the elevator apparatus of fig. 1, a car 1 and a counterweight 2 are connected to each other by a main sling 3 in a hoistway (not shown). Suspended by a bucket. The main rope 3 is wound around a sheave 4 and a diverting pulley 5 of a hoisting machine disposed in a hoistway or a machine room (not shown). Thereby, the car 1 and the counterweight 2 are suspended in the hoistway by the main suspension rope 3.
When the sheave 4 is rotationally driven by the motor 6, the main suspension wire 3 is friction-driven by the sheave 4. Thereby, the car 1 and the counterweight 2 move up and down in the hoistway.
The motor 6 is driven by a motor driving device 10 provided with a power conversion device for supplying power to the motor 6. The motor driving device 10 performs driving control of the motor 6 in accordance with a command signal from the operation control device 20.
As described below, the operation control device 20 includes an operation control unit 21, a storage device 22 storing control programs (23 to 25), an operation mode determination unit 26, a call reception unit 27, a stop floor determination unit 28, and a notification means control unit 29. In the present embodiment, the operation control device 20 is constituted by a computer system such as a microcomputer. By executing a predetermined control program by a computer system, a command signal corresponding to an operation mode is generated.
The operation control unit 21 generates a command signal for the motor drive device 10 according to the switching operation of the operation panel 30 provided in the car 1. The operation panel 30 includes a car call button switch for designating a destination floor and a maintenance switch operated by a maintenance technician during maintenance work. The maintenance switch is located in the operation panel 30, and can be operated when a maintenance technician unlocks the lockable cover in the operation panel 30 by a carried key, thereby opening the lockable cover. Therefore, the maintenance switch is not a switch operated by a general elevator user, and is dedicated to a maintenance technician in the present embodiment.
An operation signal based on the switching operation of the operation panel 30 is transmitted to the operation control device 20 via a wire connected to the operation panel 30, an on-car terminal device 40 connected to the wire, and a tail cable 50 connected to the on-car terminal device 40. The operation control device 20 generates a command signal for controlling the operation of the car 1 using the operation control unit 21 based on the operation signal transmitted from the operation panel 30.
The call receiving unit 27 receives a car call generated by operating a car call button switch in an operation signal from the operation panel 30. The call receiving unit 27 registers the received car call. The operation control unit 21 operates the car 1 based on the registered car call. The call receiving unit 27 registers or does not register a car call based on the determination results of the operation mode determining unit 26 and the stop floor determining unit 28, which will be described later. The call receiving unit 27 determines the operation state (normal operation, special operation (long press, etc.)) of the car call button switch, and registers or does not register the car call based on the determination result.
The operation mode determination unit 26 determines, based on a signal generated by operating the maintenance switch among the operation signals from the operation panel 30, which of the normal operation mode (in the case of no signal), the maintenance operation mode, and the dedicated operation mode the operation mode of the car 1 is. The operation control unit 21 sets the operation mode determined by the operation mode determination unit 26.
In the normal operation, the normal operation mode is set for the operation control unit 21 as the operation mode of the car 1. When the normal operation mode is set, the operation control unit 21 selects the normal operation control program 23 stored in the storage device 22 as the operation control means. The operation control unit 21 generates an operation command signal for normally operating the car 1 by using normal operation control means, that is, by executing the normal operation control program 23, based on an operation of a car call button switch provided on the operation panel 30 and an operation of a landing call button switch not shown.
In the maintenance operation, when a maintenance operation change-over switch among maintenance switches provided in the operation panel 30 is operated, a maintenance operation mode is set as an operation mode of the car 1 in the operation control unit 21. When the maintenance operation mode is set, the operation control unit 21 selects the maintenance operation control program 24 stored in the storage device 22 as the operation control means. The operation control unit 21 generates an operation command signal for operating and stopping the car 1 in the up-down direction at a speed lower than the rated speed in the normal operation by using the maintenance operation control means, that is, by executing the maintenance operation control program 24, in accordance with the operation of the maintenance operation switch in the maintenance switch.
In the maintenance operation, when a dedicated operation change-over switch among maintenance switches provided in the operation panel 30 is operated, a dedicated operation mode is set for the operation control unit 21 as an operation mode of the car 1. When the dedicated operation mode is set, the operation control device 20 selects the dedicated operation control program 25 stored in the storage device 22 as the operation control unit. Then, the operation control unit 21 generates an operation command signal for operating the car 1 at the same speed as in the normal operation, based on the operation of the car call button switch. In the case of the dedicated operation mode, the operation control device 20 invalidates the operation of the landing call button switch. That is, the operation control device 20 responds only to the operation of the car call button switch in the operation of the car call button switch and the landing call button switch. That is, the car 1 runs to the destination floor where the maintenance technician operates the car call button switch to register.
The notification means control unit 29 controls notification means such as a sound generation device in accordance with an instruction from the operation control unit 21 or in accordance with an operation state of the operation control unit 21. In the present embodiment, the notification means is provided in the car 1 to notify the inside of the hoistway and the inside of the car 1 that the car 1 is in a dedicated operation.
Fig. 2 is a flowchart showing control performed by the operation control device according to the present embodiment in the dedicated operation mode.
When the process is started, in step S1, the operation control device 20 determines whether or not the car call button of the floor (e.g., the lowest floor) of the lower end floor area, for example, of the end floor area within the car call buttons in the operation panel 30 is pressed based on the operation signal from the operation panel 30, using the call receiving unit 27. If it is determined that the car call button of the floor in the end floor area is not pressed (no in step S1), the operation control device 20 ends a series of processes, and if it is determined that the car call button is pressed (yes in step S1), then step S2 is executed.
In step S2, the operation control device 20 uses the stop floor determination unit 28 to determine whether or not the end floor near-front area is included in the travel section of the car 1 up to the floor of the end floor area designated as the destination floor by the car call button, that is, the travel section of the car 1 traveling before reaching the destination floor. If the operation control device 20 determines that the end floor near-front area is included (yes in step S2), it proceeds to step S3, and if the end floor near-front area is not included (no in step S2), it proceeds to step S6.
In step S3, the operation control device 20 uses the stop floor determination unit 28 to determine whether or not a stop floor exists in the area immediately before the end floor in the travel section of the car 1. If the operation control device 20 determines that the stop floor exists (yes in step S3), it proceeds to step S4, and if it determines that the stop floor does not exist (no in step S3), it proceeds to step S6.
In step S4, the operation control device 20 registers a car call corresponding to the pressed car call button, that is, the car call button of the floor of the end floor area, using the call receiving unit 27, and starts the car 1 from the stopped floor toward the destination floor designated by the car call button using the operation control unit 21. After executing step S4, the operation control device 20 then executes step S5.
In step S5, the operation control device 20 stops the car 1 at the floor closest to the end floor area among the stop floors in the area immediately before the end floor, using the operation control unit 21. When stopping at the stop floor in the area immediately before the end floor, the maintenance technician proceeds to the destination floor by performing a predetermined operation (for example, pressing the close button for a long time before departure). The travel may be restarted after a predetermined time has elapsed.
After executing step S5, the operation control device 20 then executes step S8.
In step S8, the operation control device 20 uses the notification means control unit 29 to sound a buzzer provided in the car 1, and uses the operation control unit 21 to move the car 1 to the floor where the car call is registered, that is, the floor in the end floor area. Then, the operation control device 20 stops the car 1 by stopping it at the floor using the operation control unit 21, and stops the sounding of the buzzer using the notification means control unit 29. Such a buzzer sounds, and the approach of the car 1 to the end floor area can be reliably notified.
In the present embodiment, the buzzer is provided to generate a beeping sound into the hoistway on the car 1 outside the car room of the car 1. The buzzer is not limited to being provided in the car 1, and may be provided in the car 1 at a position where a buzzer sound can be generated in the hoistway. As the buzzer, an electromagnetic buzzer, an electronic buzzer, or the like can be applied.
The present invention is not limited to a buzzer, and can be applied to a sound generating device such as an electromagnetic clock or an electronic clock. Since the sound generated from the sound generating device is reverberated in the hoistway, the approach of the car 1 can be reliably notified.
As described above, in step S2, when the operation control device 20 determines that the end floor near-front area is not included in the travel area (no in step S2), or when the operation control device 20 determines that the stop floor is not present in the end floor near-front area in step S3 (no in step S3), the operation control device 20 next executes step S6.
In step S6, the operation control device 20 determines whether or not the car call button has been pressed for a long time, using the call receiving unit 27, and in the present embodiment, determines whether or not the car call button has been pressed for 5 seconds or more. When the long press is not determined (no in step S6), the operation control device 20 ends the series of processing, and when the long press is determined, the process proceeds to step S7.
In step S7, as in step S4, the operation control device 20 registers a car call corresponding to the pressed car call button, that is, the car call button of the floor of the end floor area, using the call receiving unit 27, and starts the car 1 from the stopped floor toward the destination floor designated by the car call button using the operation control unit 21. After executing step S7, the operation control device 20 then executes step S8.
In step S8, the operation control device 20 uses the notification means control unit 29 to sound a buzzer provided in the car 1, and uses the operation control unit 21 to move the car 1 toward the floor where the car call is registered, that is, the floor in the end floor area. Then, the operation control device 20 stops the car 1 by stopping it at the floor using the operation control unit 21, and stops the sounding of the buzzer using the notification means control unit 29. Such a buzzer sounds, and the approach of the car 1 to the end floor area can be reliably notified.
As described above, in the dedicated operation mode, the operation control device 20 operates the car in response to the car call as in the normal operation mode, but reports the approach to the destination floor by making the operation state of the car 1 different from the normal operation. In the present embodiment, the travel of the car 1 is temporarily stopped before reaching a floor of an end floor area that is a destination floor, or the car 1 is caused to travel while sounding a buzzer.
In the present embodiment, the operation control device 20 makes the operation state of the car 1 different depending on whether or not a floor registered as a stop floor is present in an end floor area adjacent to an end floor area where a destination floor is located in a traveling section of the car 1. That is, as described above, if there is a floor as a stop floor, the operation control device 20 temporarily stops the car 1 at the floor, and if there is no floor as a stop floor, the car 1 is caused to travel while sounding a buzzer. Here, the stop floor is a floor at which the car 1 responds to a car call or a landing call in normal operation. Thus, the travel control device 20 causes the car 1 to travel in an appropriate travel state according to the presence or absence of the stop floor in order to notify the approach of the car 1, and thus can reliably notify the approach of the car 1.
Fig. 3 shows an example of the operation of the car based on the operation control shown in fig. 2 (cases 1 to 4). In either case, in the dedicated operation mode, the maintenance technician operates the car call button of the operation panel in the car stopped at a certain floor, and registers a car call in which the floor in the end floor area is the destination floor.
In case 1, in steps S2 and S3 in fig. 2, it is determined that the travel area has an end floor near-front area (for example, a range of 6m from the lowest floor) and a stop floor in the end floor near-front area (for example, a range of 10m adjacent to the end floor area), respectively. In this case, the car stops by being parked at a stop floor in the area immediately before the end floor. In case 1, the car stops at the stop floor closest to the end floor area. This makes it possible to reliably notify the end floor area of the approach of the car. After stopping at the stop floor in the area immediately before the end floor, the car proceeds to the destination floor by performing a predetermined operation (for example, by pressing a close button for a long time before departure) by a maintenance technician. After stopping the operation for a predetermined time set in advance in the operation control device, the buzzer is sounded and the vehicle travels to the destination floor. In addition, the travel may be restarted after a predetermined time has elapsed.
In case 2, as in case 1, it is determined that the travel area has an end floor near zone and the end floor near zone has a stop floor in steps S2 and S3 of fig. 2, respectively. In case 2, among the plurality of floors (two floors in fig. 3) in the area immediately before the end floor, a stop floor and a no-stop floor are included. In case 2, the car also stops at the stop floor closest to the end floor zone. Therefore, in case 2, the floor above the stop floor registered as the stop floor in the two floors in the area immediately before the end floor is stopped for a predetermined time. After stopping at the stop floor in the area immediately before the end floor, the maintenance technician proceeds to the destination floor by performing a predetermined operation (for example, pressing the close button for a long time before departure). The travel may be restarted after a predetermined time has elapsed. The car passes through the non-stop floor in the area in front of the end floor while sounding the buzzer, and travels to the destination floor.
In case 3, since the car on which the maintenance technician sits is stopped at the end floor area, the area immediately before the end floor is not included in the travel section of the car up to the destination floor (lowest floor), and therefore, the car call button is pushed for a long time in order to travel the car to the destination floor while sounding the buzzer.
In case 3, in step S2 of fig. 2, it is determined that there is no end floor near zone between traveling zones. Then, since the car call button is pressed for a long time (yes in step S6 of fig. 2), the car travels to the destination floor (lowest floor in fig. 3) while sounding the buzzer. When the car call button is not pressed for a long time, the operation control device ends the series of processing (no in step S6 in fig. 2) as described above, and thus the car call is not registered, and the car does not start traveling.
In case 4, since there is no stop floor in the area immediately before the end floor, the maintenance technician presses the car call button for a long time in order to make the car travel to the destination floor while sounding the buzzer. In case 4, it is determined in steps S2 and S3 in fig. 2 that there is an end floor near zone in the travel section and there is no stop floor in the end floor near zone. Therefore, the car travels to the destination floor (the lowest floor in fig. 3) through the end floor near-front area while sounding the buzzer. If the car call button is not pressed for a long time, the car call is not registered as in case 3, and the car does not start traveling.
As shown in the operation example of fig. 3, in the present embodiment, in the dedicated operation mode, when the traveling section of the car up to the destination floor in the end floor area includes the end floor near-front area having the stop floor, the car stops by being stopped temporarily at the stop floor. This makes it possible to notify the end floor area of the approach of the car. After that, the car travels to the destination floor while sounding a buzzer. This makes it possible to reliably notify the end floor area of the approach of the car. In addition, by such an operation, the safety of the maintenance technician riding in the car is further improved.
As shown in the operation example of fig. 3, in the present embodiment, in the exclusive operation mode, the car travels to the destination floor without stopping halfway while sounding the buzzer, in the case where the end floor near-front region including the stop floor is not included in the travel section of the car up to the destination floor in the end floor region, and in the case where the floor located in the end floor near-front region is only the non-stop floor. This makes it possible to reliably notify the end floor area of the approach of the car.
The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments are embodiments described in detail for easily explaining the present invention, and are not limited to the embodiments having all the configurations described. In addition, some of the structures of the embodiments may be added, deleted, or replaced with other structures.
For example, the exclusive operation is not limited to the travel to the lower end floor (for example, the lowermost floor) as described above, and may travel to the upper end floor (for example, the uppermost floor).
The means for notifying the approach of the car is not limited to the buzzer, and may be a light emitting device. The communication device provided in the operation control device may be used to transmit a signal for notifying the approach of the car to the maintenance terminal device carried by the maintenance technician.
The elevator may be an elevator having a machine room provided with a hoist and a travel control device, or may be a so-called elevator without a machine room in which the hoist and the travel control device are provided in a hoistway.
