Detailed Description

The present invention is explained in detail with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Duplicate descriptions are appropriately simplified or omitted.

Embodiment 1.

As shown in fig. 1, an elevator 1 includes a hoistway 2, a hoisting machine 3, ropes 4, a car 5, a counterweight 6, and a control device 7. The hoistway 2 is formed to penetrate each floor of a building not shown, for example. The hoisting machine 3 is installed in, for example, a machine room not shown. The ropes 4 are wound around the traction machine 3. A car 5 and a counterweight 6 are suspended in the hoistway 2 by ropes 4. The car 5 and the counterweight 6 are lifted and lowered by driving the hoisting machine 3. The hoisting machine 3 is controlled by a control device 7.

The control device 7 is electrically connected to the hoisting machine 3 and the maintenance device 8. The maintenance device 8 has a function of communicating with the monitoring center 9.

The control device 7 and the maintenance device 8 are provided in, for example, a building in which the elevator 1 is installed. The monitoring center 9 is provided, for example, in a building different from the building in which the elevator 1 is provided. The monitoring center 9 is, for example, a server or the like provided in a management company of the elevator 1.

Fig. 2 is an external view of a landing of an elevator.

As shown in fig. 2, a landing door 10 and a landing operating panel 11 are provided in a landing. The landing doors 10 and the landing operating panel 11 are provided at, for example, each floor where the car 5 can stop. The landing operating panel 11 is provided on a wall surface near the landing door 10, for example. The landing operation panel 11 includes, for example, a landing call button 12 and a landing notification section 13. The hall call buttons 12 are provided with, for example, an up direction button 12a and a down direction button 12 b. The landing notification section 13 includes, for example, a landing monitor 14 and a landing speaker 15. The landing notification section 13 may be provided separately from the landing operating panel 11. The landing notification section 13 may be provided in, for example, three boxes of the landing door 10.

The landing call button 12 functions as an operation section of an elevator. The hall call button 12 receives an operation to generate a hall call. The upward direction button 12a is used to generate a hall call targeted for the upward direction, for example. The downward direction button 12b is used to generate a hall call targeted for the downward direction, for example.

The hall notification section 13 notifies information to the hall. The landing monitor 14 has a function of displaying visual information such as characters and images. The hall speaker 15 has a function of playing voice information such as a buzzer sound and a voice broadcast.

Fig. 3 is an external view of the inside of a car of an elevator.

As shown in fig. 3, the car 5 is provided with a car door 16 and an in-car operation panel 17. The in-car operation panel 17 is provided on a wall surface or the like near the car door 16, for example. The in-car operation panel 17 includes, for example, a door opening button 18, a door closing button 19, a destination floor button 20, and an in-car notification unit 21. The destination floor buttons 20 are provided in plural numbers, for example. The in-car notification unit 21 includes, for example, an in-car monitor 22 and an in-car speaker 23. The in-car notification unit 21 may be provided separately from the in-car operation panel 17.

The door opening button 18, the door closing button 19, and the destination floor button 20 operate as an operation unit of the elevator. The destination floor buttons 20 are provided corresponding to the floors at which the car 5 can stop, for example. The destination floor button 20 receives, for example, an operation of generating a car call to which the corresponding floor is a destination.

The in-car notification unit 21 notifies information to the inside of the car 5. The in-car monitor 22 has a function of displaying visual information such as characters and images. The in-car speaker 23 has a function of playing voice information such as a buzzer sound and a voice broadcast.

Fig. 4 is a functional block diagram of the control device in embodiment 1.

As shown in fig. 4, the control device 7 is electrically connected to the hoisting machine 3, the up direction button 12a, the down direction button 12b, the landing notification section 13, the door opening button 18, the door closing button 19, the destination floor button 20, the in-car notification section 21, and the weighing device 24. The control device 7 includes a call registration unit 25, an operation control unit 26, a storage unit 27, a failure determination unit 28, a notification control unit 29, a current detection unit 30, a weighing value detection unit 31, a full determination unit 32, and a threshold setting unit 33.

The weighing device 24 measures the load weight of the car 5. The weighing device 24 is provided at an end of the rope 4, a floor of the car 5, or the like, for example.

When an operation portion provided in a hall of the elevator 1 or the car 5 is normally operated, the call registration portion 25 registers a call corresponding to the operated operation portion. For example, when the up direction button 12a or the down direction button 12b is pressed, the call registration section 25 registers a hall call in a direction corresponding to the pressed button. For example, when the destination floor button 20 is pressed, the call registration section 25 registers a car call corresponding to the pressed destination floor button 20.

The operation control unit 26 controls the operation of the elevator 1 by controlling the driving of the hoisting machine 3. That is, the operation control unit 26 controls the movement of the car 5. The operation control unit 26 responds to the car 5 with, for example, a hall call and a car call that are registered.

The storage unit 27 stores, for example, call registration history and operation history. The call registration history includes information indicating the date and time when the call was registered, the operated hall call button 12, the operated destination floor button 20, and the like, for example. The operation history includes information indicating, for example, the date and time when the car 5 starts moving, the date and time when the car 5 stops, the floor on which the car 5 stops, and the like.

The failure determination unit 28 determines whether or not a failure has occurred in the operation unit of the elevator 1. The failure determination unit 28 determines whether or not the hall call button 12 and the destination floor button 20 have failed, based on, for example, the call registration history and the operation history.

For example, when an upward hall call corresponding to a certain upward button 12a is not registered for a predetermined period and the car 5 has moved in the upward direction for the predetermined period, the failure determination unit 28 determines that the upward button 12a has failed. For example, when a hall call in the downward direction corresponding to a certain downward direction button 12b is not registered for a predetermined period and the car 5 has moved in the downward direction for the predetermined period, the failure determination unit 28 determines that a failure has occurred in the downward direction button 12 b. That is, for example, when a state in which a hall call is not registered by a normal operation on a certain hall call button 12 continues for a predetermined time or longer, the failure determination unit 28 determines that the hall call button 12 has failed.

The predetermined period used for determining the failure of the hall call buttons 12 can be set for each building, each elevator, each floor, each hall, each time zone, each hall operating panel 11, each individual hall call button 12, or the like, for example. The predetermined period may be set for each floor, for example, based on the frequency with which floor calls are registered at ordinary times. That is, for example, when focusing attention on a certain hall call button 12, when deriving from the operation history a hall call realized by the button that is registered on average at least once every 3 minutes, a period of 3 minutes or more may be set as the predetermined period.

For example, when a car call corresponding to a certain destination floor button 20 is not registered for a predetermined period and the car 5 has moved for the predetermined period, the failure determination unit 28 determines that a failure has occurred in the destination floor button 20. That is, for example, when a state in which a car call based on a normal operation on a certain destination floor button 20 is not registered continues for a predetermined time or longer, the failure determination unit 28 determines that a failure has occurred in the destination floor button 20.

The predetermined period used for determining the failure of the destination floor buttons 20 may be set for each building, each elevator 1, each car 5, each time zone, or each individual destination floor button 20, for example. The predetermined period may be set for each individual destination floor button 20, for example, based on the frequency with which car calls are registered at ordinary times. That is, for example, when focusing attention on a certain destination floor button 20, when a car call realized by the button is derived from the operation history, which is registered once or more every 10 minutes on average, the period of 10 minutes or more may be set as the predetermined period.

When the failure determination unit 28 determines that the operating unit has failed, the special operation of the operating unit of the elevator 1 is enabled. The special operation is an operation performed on at least one normal operation unit installed in the same place as the operation unit determined by the failure determination unit 28 to have failed. The special operations include landing special operations and in-car special operations. The normal operation unit is an operation unit that is not determined by the failure determination unit 28 as having a failure.

The notification control section 29 controls the operations of the hall notification section 13 and the in-car notification section 21, which are notification sections of the elevator 1. The notification control unit 29 notifies information for guiding a special operation from a notification unit provided in the same landing or the same car 5 as the operation unit determined by the failure determination unit 28 to have a failure.

The landing special operation may be, for example, a normal landing call button 12 being continuously pressed for a predetermined time or longer. The hall special operation may be, for example, repeatedly pressing the normal hall call button 12a predetermined number of times or more for a predetermined time.

For example, when a hall special operation is performed on a normal down direction button 12b provided at the same hall as the up direction button 12a determined to have failed, the call registration section 25 registers a hall call in the up direction. For example, when a hall special operation is performed on a normal upstream direction button 12a provided in the same hall as the downstream direction button 12b determined to have failed, the call registration section 25 registers a hall call in the downstream direction.

Even if the hall special operation is enabled, when a normal hall call button 12 is normally operated, a hall call in a direction corresponding to the normal hall call button 12 is registered.

The in-car special operation may be, for example, simultaneously pressing a plurality of normal destination floor buttons 20 adjacent to the destination floor button 20 determined to have failed. That is, for example, the in-car special operation when the destination floor button 20 corresponding to the floor 5 has failed may be to simultaneously press the normal destination floor button 20 corresponding to the floor 4 and the normal destination floor button 20 corresponding to the floor 6. The in-car special operation may be, for example, repeatedly pressing the door-open button or the door-close button provided in the same car 5 as the destination floor button 20 determined to have failed the same number of times as the number of floors of the destination floor.

For example, when an in-car special operation is performed on a normal destination floor button 20 or the like provided in the same car 5 as the destination floor button 20 determined to have failed, the call registration section 25 registers a car call corresponding to the destination floor button 20 determined to have failed.

Even if the in-car special operation is enabled, if a normal operation is performed on the normal destination floor button 20, a car call corresponding to the normal destination floor button 20 is registered.

The current detection unit 30 detects a motor current of the hoisting machine 3. The weighing value detection unit 31 detects the measurement value of the weighing device 24. The detection by the current detection unit 30 and the weighing value detection unit 31 is performed, for example, when the car 5 stops and opens the door.

The full determination unit 32 determines that the car 5 is full when the value detected by the weighing value detection unit 31 is greater than a preset full determination threshold value. When it is determined that the car 5 is full, the notification control unit 29 notifies warning information from the in-car notification unit 21, for example. When it is determined that the car 5 is full, the operation control unit 26 does not start moving the car 5, for example.

When the load applied to the hoisting machine 3 becomes an overload, an overcurrent flows through the motor. When an overcurrent is detected by the current detection unit 30, a value detected by the weighing value detection unit 31 when the overcurrent is detected is recorded. This value is stored in the storage unit 27, for example.

The threshold setting unit 33 has a function of changing the full determination threshold. For example, when the car 5 responds to an upward call next after the overcurrent is detected by the current detection unit 30, the threshold setting unit 33 sets the value detected by the weighing value detection unit 31 when the overcurrent is detected as the full determination threshold. In this case, since the full determination threshold is lowered, the number of persons that can get on the car 5 is limited at once.

For example, when the car 5 next responds to a call in the down direction after the overcurrent is detected by the current detection unit 30, the threshold setting unit 33 does not change the full determination threshold. In this case, the drive control unit 26 may perform the following control: the car 5 is not started to move until the weighing value detection unit 31 detects a value equal to or greater than the value detected by the weighing value detection unit 31 when the overcurrent is detected.

Fig. 5 is a flowchart 1 showing an operation example of the control device in embodiment 1. Fig. 5 shows the operation of the control device when the landing call button 12 has failed.

The control device 7 determines whether or not there is a hall call button 12 determined to be defective (step S101). If there is no hall call button 12 determined to be defective, the process of step S101 is repeated. When there is a hall call button 12 determined to be defective, the hall special operation is enabled (step S102). After step S102, guidance regarding the hall special operation is notified to the hall (step S103).

The control device 7 determines whether or not the normal hall call button 12 is pressed (step S104). When the normal hall call button 12 is not pressed, the process of step S104 is repeated. When the normal hall call button 12 is pressed, the control device 7 determines whether or not a hall special operation is performed (step S105).

When it is determined in step S105 that the hall special operation is performed, the control device 7 registers a hall call corresponding to the hall call button 12 determined to be faulty (step S106). When it is determined in step S105 that the hall special operation has not been performed, the control device 7 registers a hall call corresponding to the normal hall call button 12 (step S107).

Fig. 6 is a flow chart of fig. 2 showing an operation example of the control device in embodiment 1. Fig. 6 shows the operation of the control device when a failure occurs in the destination floor button 20.

The control device 7 determines whether or not there is a destination floor button 20 determined to be a failure (step S201). If there is no destination floor button 20 determined to be a failure, the process of step S201 is repeated. If there is a destination floor button 20 determined to be defective, the in-car special operation is enabled (step S202). After step S202, guidance for the in-car special operation is notified to the inside of the car 5 (step S203).

The control device 7 determines whether or not the normal destination floor button 20 is pressed (step S204). If the normal destination floor button 20 is not pressed, the process of step S204 is repeated. When the normal destination floor button 20 is pressed, the control device 7 determines whether or not the in-car special operation is performed (step S205).

When it is determined in step S205 that the in-car special operation has been performed, the control device 7 registers a car call corresponding to the destination floor button 20 determined to be defective (step S206). If it is determined in step S205 that the in-car special operation has not been performed, the control device 7 registers a car call corresponding to the pressed destination floor button 20 (step S207).

Fig. 7 is a 3 rd flowchart showing an operation example of the control device in embodiment 1. Fig. 7 shows an operation of the control device when an overcurrent flows through the motor of the hoisting machine 3.

The control device 7 determines whether an overcurrent flows through the motor of the hoisting machine 3 (step S301). When no overcurrent flows through the motor of the hoisting machine 3, the process of step S301 is repeated. When an overcurrent flows through the motor of the hoisting machine 3, the control device 7 stores the measurement value of the weighing device 24 when the overcurrent flows (step S302).

The control device 7 determines whether or not a call has been registered (step S303). When the call is not registered, the process of step S303 is repeated. When a call is registered, the control device 7 determines whether or not the call to which the car 5 responds next is an up call (step S304).

When it is determined in step S304 that the call to which the car 5 next responds is an upward call, the control device 7 sets the stored measurement value of the weighing device 24 as the full state determination threshold value (step S305). When it is determined in step S304 that the call to which the car 5 next responds is a downward call, the control device 7 does not change the full determination threshold value (step S306).

In embodiment 1, when an operating portion provided in a hall of the elevator 1 or the car 5 is operated, the call registration portion 25 registers a call corresponding to the operated operating portion. Failure determination unit 28 determines whether or not the operation unit has failed. When a predetermined special operation is performed on at least one normal operating portion provided in the same hall or the same car 5 as the operating portion determined by the failure determination unit 28 to have failed, the call registration unit 25 registers a call corresponding to the operating portion determined to have failed. Therefore, according to embodiment 1, the failed operation unit can be replaced with another normal operation unit. As a result, a reduction in convenience when the operating portion of the elevator has failed can be suppressed. Further, since a time margin can be obtained until the maintenance spot check is performed, the burden on the maintenance worker can be reduced.

In embodiment 1, when an operation is performed on an up-direction button 12a or a down-direction button 12b, which is a hall call button 12, provided at a hall of an elevator 1, the call registration section 25 registers a hall call corresponding to the operated hall call button 12. The failure determination unit 28 determines whether or not the hall call button 12 has failed. When a normal down direction button 12b provided at the same hall as the up direction button 12a determined to have failed by the failure determination unit 28 is specially operated, the call registration unit 25 registers a hall call in the up direction. When a normal upward direction button 12a provided at the same hall as the downward direction button 12b determined to have failed by the failure determination unit 28 is specially operated, the call registration unit 25 registers a hall call in the downward direction. Therefore, according to embodiment 1, the malfunctioning hall call button 12 can be replaced with another normal hall call button 12. As a result, it is possible to suppress a decrease in convenience when the hall call button 12 of the elevator fails.

In embodiment 1, when an upward hall call corresponding to a certain upward button 12a is not registered for a predetermined period and the car 5 has moved in the upward direction for the predetermined period, the failure determination unit 28 determines that the upward button 12a has failed. When a hall call in the downward direction corresponding to a certain downward direction button 12b is not registered for a predetermined period of time and the car 5 has moved in the downward direction for the predetermined period of time, the failure determination unit 28 determines that a failure has occurred in the downward direction button 12 b. Therefore, according to embodiment 1, it is possible to determine whether or not the hall call button 12 has failed with a simple configuration.

In embodiment 1, when a destination floor button 20 provided in a car 5 of an elevator 1 is operated, a call registration section 25 registers a car call corresponding to the operated destination floor button 20. The failure determination unit 28 determines whether or not the destination floor button 20 has failed. When a special operation is performed on a normal operating portion provided in the same car 5 as the destination floor button 20 determined to have failed by the failure determination unit 28, the call registration unit 25 registers a car call corresponding to the destination floor button 20 determined to have failed. Therefore, according to embodiment 1, the failed destination floor button 20 can be replaced with another normal destination floor button 20 or the like. As a result, it is possible to suppress a decrease in convenience when the destination floor button 20 of the elevator fails.

In embodiment 1, when a car call corresponding to a certain destination floor button 20 is not registered for a predetermined period and the car 5 moves for the predetermined period, the failure determination unit 28 determines that the destination floor button 20 has failed. Therefore, according to embodiment 1, it is possible to determine whether or not the destination floor button 20 has failed with a simple configuration.

In embodiment 1, the notification control unit 29 notifies the following information from a notification unit provided in the same hall or the same car 5 as the operation unit determined by the failure determination unit 28 to have a failure: the information guides a special operation for registering a call corresponding to the operation portion determined to have a failure. Therefore, according to embodiment 1, guidance for special operation can be provided to the user of the elevator. As a result, a reduction in convenience when the operating portion of the elevator has failed can be suppressed.

In embodiment 1, the current detection unit 30 detects the motor current of the hoisting machine 3 of the elevator 1. The weighing value detection unit 31 detects a measurement value of the weighing device 24 that measures the load weight of the car 5 of the elevator 1. The full determination unit 32 determines that the car 5 is full when the value detected by the weighing value detection unit 31 is greater than a preset full determination threshold value. When an overcurrent is detected by the current detection unit 30 and the car 5 responds to an upward call, the threshold setting unit 33 sets the value detected by the weighing value detection unit 31 when the overcurrent is detected as the full determination threshold. Therefore, according to embodiment 1, after detecting that an overcurrent has flowed through the motor of the hoisting machine 3, the operation of the elevator 1 can be continued in a state in which the load on the motor is reduced compared to normal. As a result, it is possible to suppress a reduction in convenience until maintenance check is performed on the hoisting machine of the elevator.

In embodiment 1, for example, when a special operation is enabled in response to a determination that a failure has occurred in a certain operating part, or when a call based on a normal operation for the operating part is registered, the special operation is disabled. That is, for example, even if a normal operating unit is determined to have a failure due to a small number of accidental occurrences of the user of the elevator 1, the special operation is invalidated as long as the normal operating unit is operated. Therefore, unnecessary special operations can be prevented from continuing to be effective.

In embodiment 1, for example, the notification control unit 29 may notify the monitoring center 9 via the maintenance device 8 that it is determined that the operation unit of the elevator 1 has failed, that an overcurrent has flowed through the motor of the hoisting machine 3, or the like. In this case, for example, a maintenance worker of the elevator 1 can quickly grasp the situation of the elevator 1.

Fig. 8 is a hardware configuration diagram of the control device.

The functions of the call registration unit 25, the operation control unit 26, the storage unit 27, the failure determination unit 28, the notification control unit 29, the current detection unit 30, the weighing value detection unit 31, the full determination unit 32, and the threshold setting unit 33 in the control device 7 are realized by processing circuits. The processing circuitry may be dedicated hardware 50. The processing circuit may also have a processor 51 and a memory 52. A part of the processing circuit may be dedicated hardware 50, and further, may include a processor 51 and a memory 52. Fig. 8 shows an example of a case where a part of the processing circuit is formed as dedicated hardware 50 and provided with a processor 51 and a memory 52.

Where at least a portion of the processing circuitry is at least one dedicated hardware 50, the processing circuitry corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

When the processing circuit includes at least one processor 51 and at least one memory 52, the functions of the call registration unit 25, the operation control unit 26, the storage unit 27, the failure determination unit 28, the notification control unit 29, the current detection unit 30, the weighing value detection unit 31, the fullness determination unit 32, and the threshold setting unit 33 are realized by software, firmware, or a combination of software and firmware. The software and firmware are described as programs and are stored in the memory 52. The processor 51 realizes the functions of the respective sections by reading out and executing the program stored in the memory 52. The processor 51 is also called a CPU (Central Processing Unit), a Central Processing Unit, a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The Memory 52 corresponds to a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a magnetic Disk, a floppy Disk, an optical Disk, a CD (compact Disk), a mini Disk (mini Disk), a DVD (Digital Versatile Disk), and the like.

In this way, the processing circuitry can implement the functions of the control device 7 using hardware, software, firmware, or a combination thereof.

Industrial applicability

Claims

1. A control device for an elevator, comprising:

a call registration section that registers a hall call corresponding to a hall call button that is operated when an upward direction button or a downward direction button that is a hall call button provided as an operation section at a hall of an elevator is operated; and

a failure determination unit that determines whether or not a landing call button has failed,

the call registration section registers a hall call in an upstream direction when a special operation is performed on a normal downstream direction button provided at the same hall as an upstream direction button determined to have failed by the failure determination section, and registers a hall call in a downstream direction when a special operation is performed on a normal upstream direction button provided at the same hall as a downstream direction button determined to have failed by the failure determination section.

2. The control device of an elevator according to claim 1,

the failure determination unit determines that a failure has occurred in an upward direction button when an upward direction hall call corresponding to the upward direction button is not registered for a predetermined period and the car has moved in the upward direction for the predetermined period, and determines that a failure has occurred in a downward direction button when a downward direction hall call corresponding to the downward direction button is not registered for a predetermined period and the car has moved in the downward direction for the predetermined period.

3. A control device for an elevator, comprising:

a call registration section that, when a destination floor button that is an operation section provided in a car of an elevator is operated, registers a car call corresponding to the operated destination floor button; and

a failure determination unit for determining whether or not a failure has occurred in the destination floor button,

when a normal operation portion provided in the same car as the destination floor button determined to have failed by the failure determination unit is specially operated, the call registration portion registers a car call corresponding to the destination floor button determined to have failed,

the failure determination unit determines that a failure has occurred in a destination floor button when a car call corresponding to the destination floor button is not registered for a predetermined period and the car has moved for the predetermined period.

4. The control device of an elevator according to any one of claims 1 to 3,

the control device for an elevator includes a notification control unit that notifies a notification unit provided in the same landing or the same car as the operation unit determined by the failure determination unit that a failure has occurred, of: the information guides a special operation for registering a call corresponding to the operation portion determined to have a failure.

5. A control device for an elevator, comprising:

a call registration section that registers a call corresponding to an operation section provided in a hall or a car of an elevator when the operation section is operated;

a failure determination unit that determines whether or not a failure has occurred in the operation unit;

a current detection unit that detects a motor current of a hoisting machine of an elevator;

a weighing value detection unit that detects the load weight of the car of the elevator;

a full-passenger determination unit that determines that the car is full when the value detected by the weighing value detection unit is greater than a full-passenger determination threshold value; and

a threshold value setting unit that sets a value detected by the weighing value detecting unit when an overcurrent is detected as a full-state determination threshold value when the overcurrent is detected and the car responds to an upward call,

when a special operation is performed on a normal operation portion provided in the same landing or the same car as the operation portion determined to have a failure by the failure determination unit, the call registration portion registers a call corresponding to the operation portion determined to have a failure.
