Detailed Description
The invention is described with reference to the accompanying drawings. Duplicate explanations are appropriately simplified or omitted. In the drawings, the same reference numerals denote the same or equivalent parts.
Fig. 1 and 2 are diagrams showing an example of an elevator apparatus according to embodiment 1. The elevator apparatus includes a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in the hoistway 2 by the main ropes 4.
The main ropes 4 are wound around a drive sheave 6 of a hoisting machine 5. The car 1 moves in accordance with the rotation of the drive sheave 6. In the present embodiment, the drive sheave 6 is an example of a pulley that rotates as the car 1 moves.
The hoisting machine 5 is provided with an encoder 7. The encoder 7 outputs a signal corresponding to the rotation of the drive sheave 6. The signal from the encoder 7 is input to the control device 8. The control device 8 controls the hoisting machine 5. That is, the movement of the car 1 is controlled by the control device 8.
The monitoring device 9 is connected to the control device 8. The monitoring device 9 is a device for communicating with the outside via the network 10. For example, the monitoring apparatus 9 is connected to a remote monitoring center 11 via a network 10.
The monitoring means 9 are connected to the access point 12. The access point 12 is used when a specific device performs wireless communication with the monitoring apparatus 9. The specific device includes, for example, a maintenance portable terminal 13. The portable terminal 13 is held by a maintenance person of the elevator. The maintenance person uses the portable terminal 13 to perform maintenance work for the elevator.
Fig. 1 shows an example in which a hoisting machine 5, a control device 8, a monitoring device 9, and an access point 12 are disposed in a machine room above a hoistway 3. The hoisting machine 5, the control device 8, the monitoring device 9, and the access point 12 may be disposed in the hoistway 3.
The car 1 includes, for example, an operation panel 14, an operating device 15, a spot check lamp 16, and a floor stopping device 17.
The operation panel 14 is a device for inputting information by being operated by a person in the car 1. Therefore, the operation panel 14 is disposed in the car 1. Fig. 3 is a diagram showing an example of the operation panel 14. The operation panel 14 includes, for example, a destination button 21, an on button 22, and an off button 23. A general user operates the destination button 21, the on button 22, and the off button 23 in the car 1.
The operating panel 14 is also used for maintenance work of the elevator. For example, the operating panel 14 is provided with a door 24 with a lock. By opening the door 24, the dot detection switch 25 and the change-over switch 26 provided in the operation panel 14 can be operated. The spot inspection switch 25 is one of switches operated by a maintenance worker during spot inspection work. The selector switch 26 is a switch for switching the operation mode between the automatic mode and the manual mode. The automatic mode is a mode in which the car 1 sequentially responds to registered calls. The manual mode is a mode for moving the car 1 by a manual operation.
The selector switch 26 is an example of setting means for setting to the automatic mode or the manual mode. That is, when the change-over switch 26 is set to the manual mode, the car 1 can be moved by manual operation from the operation panel 14. The operation panel 14 includes a manual operation means for moving the car 1 by manual operation. For example, when the selector switch 26 is set to the manual mode, the destination button 21, the on button 22, and the off button 23 function as manual operation means. For example, a dedicated operation switch may be provided as the manual operation means on the inner side of the door 24. When the selector switch 26 is set to the manual mode, the car 1 moves in accordance with the operation of the manual operation means. On the other hand, when the changeover switch 26 is set to the automatic mode, automatic operation is performed in which the car 1 automatically responds to a registered call. A person riding in the car 1 can register a call by pressing the destination button 21.
The operation device 15 is disposed above the car 1. The running gear 15 is a device that is operated by a maintenance worker on the car 1. Fig. 4 is a diagram showing an example of the operating device 15. The operation device 15 includes, for example, a selector switch 27 and an operation button 28.
The selector switch 27 is an example of setting means for setting to the automatic mode or the manual mode. That is, when the change-over switch 27 is set to the manual mode, the car 1 can be moved by manual operation from the operation device 15. The operation button 28 is an example of a manual operation means for moving the car 1 by a manual operation. That is, when the selector switch 27 is set to the manual mode, the car 1 moves in accordance with the operation of the operation button 28. On the other hand, when the change-over switch 27 is set to the automatic mode, the car 1 cannot be moved by manual operation from the operation device 15.
The inspection lamp 16 is turned on when maintenance work of the elevator is performed. In the example shown in fig. 1, the spot check lamps 16 are disposed above the car 1 and below the car 1. The spot check lamp 16 may be disposed only on the car 1. The spot check lamp 16 may be disposed only below the car 1.
The floor stopping device 17 detects a detection object installed in the hoistway 3. The layer stopping device 17 is, for example, a magnetic sensor. The layer stopping device 17 may also be a photoelectric sensor. For example, a metal plate 29 is provided in the hoistway 3 as the subject. The plate 29 is disposed corresponding to the height of each layer station 30. For example, when the car 1 stops at the lowermost landing 30, the floor 29 provided in accordance with the height of the lowermost landing 30 is detected by the floor stopping device 17. As another example, when the car 1 stops at the top landing 30, the floor stop device 17 detects the plate 29 provided in accordance with the height of the top landing 30.
The car 1 and the control device 8 are connected by a control cable 18. The control cable 18 extends downward from the car 1. The control cable 18 extending downward from the car 1 is switched in direction and extends upward in the hoistway 3. The control cable 18 is suspended in a U-shape in the hoistway 3 so as not to obstruct movement of the car 1.
The operation device 19 is installed in the pit 3a of the hoistway 3. The operation device 19 is a device that is operated by a maintenance worker at the pit 3a of the hoistway 3. Fig. 5 is a diagram showing an example of the operating device 19. The structure of the operation device 19 is the same as that of the operation device 15. The operation device 19 includes, for example, a selector switch 31 and an operation button 32.
The selector switch 31 is an example of setting means for setting to the automatic mode or the manual mode. That is, when the change-over switch 31 is set to the manual mode, the car 1 can be moved by manual operation from the operation device 19. The operation button 32 is an example of a manual operation means for moving the car 1 by a manual operation. That is, when the change-over switch 31 is set to the manual mode, the car 1 moves in accordance with the operation of the operation button 32. On the other hand, when the change-over switch 31 is set to the automatic mode, the car 1 cannot be moved by manual operation from the operation device 19.
In the example shown in the present embodiment, the portable terminal 13 includes a maintenance switch 33. The maintenance switch 33 is one of switches that a maintenance worker operates when performing a spot inspection operation. The maintenance switch 33 may be provided on the operation panel 14 of the car 1.
As shown in fig. 2, the control device 8 includes, for example, a storage unit 40, an operation control unit 41, a condition determination unit 42, a position detection unit 43, and an abnormality detection unit 44. The operation control unit 41 controls the movement of the car 1. The position detecting unit 43 detects the position P of the car 1. For example, the position detecting unit 43 detects the position P of the car 1 based on a signal from the encoder 7. In the example shown in the present embodiment, the car 1 moves only vertically. Therefore, the "position" of the car 1 in the present embodiment is synonymous with the "height" at which the car 1 is disposed. The operation control section 41 controls the movement of the car 1 based on the position P of the car 1 detected by the position detection section 43.
The monitoring device 9 includes, for example, a reporting unit 50, a blocking unit 51, and a wireless communication unit 52. The reporting unit 50 reports to the outside when a specific abnormality is detected. In the example shown in the present embodiment, the reporting unit 50 reports to the remote monitoring center 11 when a specific abnormality is detected.
Hereinafter, the functions of the elevator apparatus will be described with reference to fig. 6 to 11. Fig. 6 to 8, 10, and 11 are flowcharts showing operation examples of the elevator apparatus according to embodiment 1.
Fig. 6 shows an example of operations of the control device 8 and the monitoring device 9 at the start of the maintenance work. For example, in the control device 8, it is determined whether or not the spot detection switch 25 is turned on (S101). When the maintenance worker starts the maintenance work, the spot check switch 25 is first turned on. When the lighting switch 25 is turned on (yes in S101), the control device 8 turns on the lighting lamp 16 (S102). Further, when the point detection switch 25 is turned on, the wireless communication section 52 permits wireless communication via the access point 12 (S103). After turning on the point detection switch 25, the maintenance person connects the portable terminal 13 to the monitoring apparatus 9 via the access point 12.
The monitoring device 9 determines whether or not the maintenance switch 33 is turned on (S104). When the maintenance person connects the portable terminal 13 to the monitoring device 9, the maintenance switch 33 is turned on. When the maintenance switch 33 is turned on, a specific signal is transmitted from the portable terminal 13 to the monitoring device 9. The monitoring device 9 receives the signal to detect that the maintenance switch 33 is turned on.
When the maintenance switch 33 is turned on (yes in S104), the blocking unit 51 blocks the report from the reporting unit 50 to the outside (S105). In some cases, a maintenance worker intentionally sets the elevator in an abnormal state during maintenance work. If it is determined yes in S104, the reporting unit 50 does not report the abnormal state to the monitoring center 11 even if the maintenance person intentionally creates the abnormal state.
Fig. 7 shows an operation example of the control device 8 when the car 1 is moved in the manual mode. The condition determination unit 42 determines whether or not a specific start condition is satisfied (S201). The start condition is one of main conditions for performing shift control described later.
Fig. 8 shows the function of the condition determining unit 42. That is, the process shown in fig. 8 is performed in S201. The condition determination unit 42 determines whether or not the external report is blocked by the blocking unit 51 (S301). For example, if the maintenance worker turns on the maintenance switch 33 when starting the maintenance work, it is determined as yes in S301. If the report to the outside is not blocked by the blocking unit 51, the start condition is not satisfied (S306).
If yes is determined in S301, the condition determination unit 42 determines whether or not the change-over switch 31 of the operating device 19 is set to the manual mode (S302). If the selector switch 31 has been set to the manual mode, it is determined as yes in S302. If the changeover switch 31 has been set to the automatic mode, the start condition is not established (S306).
If it is determined as "yes" in S302, the condition determination unit 42 determines whether or not the change-over switch 26 of the operation panel 14 is set to the manual mode (S303). If the selector switch 26 has been set to the manual mode, it is determined as yes in S303. If the changeover switch 26 has been set to the automatic mode, the start condition is not established (S306).
If it is determined as "yes" in S303, the condition determination unit 42 determines whether or not the change-over switch 27 of the operating device 15 is set to the automatic mode (S304). If the changeover switch 27 has been set to the manual mode, the start condition is not established (S306).
If the changeover switch 27 has been set to the automatic mode, it is determined as yes in S304. If yes is determined in S304, the start condition is satisfied (S305). That is, the start condition is satisfied as follows: the prevention unit 51 prevents the report to the outside, and the selector switch 26 disposed in the car 1 is set to the manual mode, the selector switch 27 disposed above the car 1 is set to the automatic mode, and the selector switch 31 disposed in the pit 3a is set to the manual mode. The respective processes of S301, S302, S303, and S304 for determining whether or not the start condition is satisfied may be performed in an arbitrary order. Note that the start condition determination shown in fig. 8 may be repeatedly performed while it is determined that the point detection switch 25 is on.
When the start condition is satisfied, the selector switch 31 disposed in the pit 3a is set to the manual mode. Therefore, when the maintenance worker operates the operation button 32 to move the car 1 in the pit 3a, the judgment in S201 may be yes. Similarly, when the start condition is satisfied, the change-over switch 26 disposed in the car 1 is set to the manual mode. Therefore, when the maintenance worker operates the manual operation means provided in the operation panel 14 in the car 1 to move the car 1, the judgment result of S201 may be yes.
When the start condition is satisfied ("yes" in S201), the control device 8 determines whether or not the operation button 32 of the operation device 19 has been operated (S202). When the start condition is satisfied and the operation button 32 is operated (yes in S202), the operation control portion 41 performs the shift control in accordance with the operation of the operation button 32 (S203).
Even when the start condition is satisfied, if the manual operation means of the operation panel 14 is operated, it is determined as no in S202. If it is determined as no in S202, the operation control unit 41 performs the constant speed control in accordance with the operation of the manual operation means with respect to the operation panel 14 (S204). When the operation button 28 is operated in a state where the selector switch 27 is set to the manual mode, it is determined as no in S201. If it is determined as no in S201, the operation control unit 41 performs the constant speed control in accordance with the operation of the operation button 28 (S204).
Fig. 9 is a diagram for explaining shift control in the manual mode. As shown in fig. 9, a zone A1, a zone A2, and a zone A3 are set in the hoistway 3. The region A1 is a region in which the car 1 is moved at the speed V1 in the manual mode. The region A2 is a region in which the car 1 is moved at the speed V2 in the manual mode. The speed V2 is a speed greater than the speed V1. The speed V2 is a speed lower than the rated speed of the car 1 in the automatic mode. For example, the speed V1 is 15m/min and the speed V2 is 37m/min. The value of the speed V1 and the value of the speed V2 are not limited to the above example.
The area A3 is an area in which the car 1 is moved at the speed V1 in the manual mode. As shown in fig. 9, the area A1 includes the lower end of the lifting range of the car 1 in the manual mode. The area A2 is disposed above the area A1. The area A3 is arranged above the areas A1 and A2. The area A3 includes the upper end of the lifting range of the car 1 in the manual mode. The region A2 is disposed above the region A1 and below the region A3.
Fig. 10 shows an example of the gear shift control when the car 1 moves upward. Fig. 10 shows an example in which the ascending speed of the car 1 is changed according to the position P of the car 1 detected by the position detecting unit 43.
For example, when the operation button 32 is operated to raise the car 1 in S202, it is determined whether the position P of the car 1 is lower than the height h1 (S401). The height h1 is set to a specific height between the areas A1 and A2.
If the position P is lower than the height h1 (yes in S401), the operation control portion 41 moves the car 1 upward so that the speed of the car 1 becomes the speed V1 (S402). Next, it is determined whether the position P of the car 1 has reached the height h1 (S403). When the position P reaches the height h1 (yes in S403), the operation control portion 41 moves the car 1 upward so that the speed of the car 1 becomes the speed V2 (S404).
Next, it is determined whether the position P of the car 1 has reached the height h2 (S405). The height h2 is set to a specific height between the area A2 and the area A3. When the position P reaches the height h2 (yes in S405), the operation control unit 41 moves the car 1 upward so that the speed of the car 1 becomes the speed V1 (S406).
On the other hand, if it is determined as no in S401, it is determined whether the position P of the car 1 is lower than the height h2 (S407). If the position P is lower than the height h2 (yes in S407), the operation control section 41 proceeds to the process of S404. That is, the operation control unit 41 moves the car 1 upward so that the speed of the car 1 becomes the speed V2. On the other hand, if the position P is higher than the height h2 (no in S407), the operation control section 41 proceeds to the process of S406. That is, the operation control unit 41 moves the car 1 upward so that the speed of the car 1 becomes the speed V1.
Fig. 11 shows an example of the gear shift control when the car 1 moves downward. Fig. 11 shows an example in which the lowering speed of the car 1 is changed in accordance with the position P of the car 1 detected by the position detecting section 43.
For example, when the operation button 32 is operated to lower the car 1 in S202, it is determined whether the position P of the car 1 is higher than the height h2 (S501). If the position P is higher than the height h2 (yes in S501), the operation control portion 41 moves the car 1 downward so that the speed of the car 1 becomes the speed V1 (S502). Next, it is determined whether the position P of the car 1 has reached the height h2 (S503). When the position P reaches the height h2 (yes in S503), the operation control unit 41 moves the car 1 downward such that the speed of the car 1 becomes the speed V2 (S504).
Next, it is determined whether the position P of the car 1 has reached the height h1 (S505). When the position P reaches the height h1 (yes in S505), the operation control portion 41 moves the car 1 downward so that the speed of the car 1 becomes the speed V1 (S506).
On the other hand, if it is determined as no in S501, it is determined whether the position P of the car 1 is higher than the height h1 (S507). If the position P is higher than the height h1 (yes in S507), the operation control section 41 proceeds to the process of S504. That is, the operation control unit 41 moves the car 1 downward so that the speed of the car 1 becomes the speed V2. On the other hand, if the position P is lower than the height h1 (no in S507), the operation control portion 41 proceeds to the process of S506. That is, the operation control unit 41 moves the car 1 downward so that the speed of the car 1 becomes the speed V1.
In the constant speed control in S204, the operation control unit 41 moves the car 1 at the speed V1 regardless of the position P of the car 1.
When the maintenance worker performs the dynamic characteristic point inspection of the control cable 18 during the maintenance work, the maintenance worker first stops the car 1 at a floor higher than the lowest floor and sets the change-over switch 26 of the operation panel 14 to the manual mode. Then, the maintenance worker enters the pit 3a of the hoistway 3 from the lowermost landing 30. Then, after setting the change-over switch 31 of the operation device 19 to the manual mode, the maintenance worker operates the operation button 32 to move the car 1.
In the example shown in the present embodiment, when the above-described start condition is satisfied, if the car 1 is in the zone A1 or the zone A3, the operation control unit 41 moves the car 1 at the speed V1 in accordance with the operation of the operation button 32. When the start condition is satisfied, the operation control unit 41 moves the car 1 at the speed V2 in accordance with the operation of the operation button 32 if the car 1 is in the area A2. Therefore, the speed of the car 1 can be increased in the area A2, and the time taken for the dynamic characteristic point inspection of the control cable 18 can be shortened.
Even if the maintenance worker operates the operation button 32 after setting the selector switch 31 to the manual mode, if the start condition is not satisfied, the constant speed control is performed in S204. That is, even if the car 1 is in the area A2, the operation control section 41 moves the car 1 at the speed V1 in accordance with the operation of the operation button 32.
In the example shown in the present embodiment, the start condition is not satisfied when the change-over switch 27 of the operation device 15 is set to the manual mode. The changeover switch 27 is operated by a person who climbs over the car 1. Therefore, the car 1 can be prevented from moving at the speed V2 when a person climbs over the car 1.
When the selector switch 26 of the control panel 14 is set to the automatic mode, the start condition is not satisfied. Therefore, it is possible to prevent the maintenance worker from being present in the pit 3a for the purpose of performing the dynamic characteristic point inspection of the control cable 18, but registering a call in the car 1.
Other functions that can be employed by the elevator apparatus will be described below. The elevator apparatus may adopt a plurality of functions described below in combination.
For example, in the gear change control in S203, the speed of the car 1 when the car 1 is in the area A1 may be different from the speed of the car 1 when the car 1 is in the area A3. For example, in the gear change control in S203, if the car 1 is in the area A3, the operation control portion 41 moves the car 1 at the speed V3 in accordance with the operation of the operation button 32. That is, in S406 of fig. 10, the operation control portion 41 moves the car 1 upward so that the speed of the car 1 becomes the speed V3. In S502 of fig. 11, the operation control unit 41 moves the car 1 downward so that the speed of the car 1 becomes the speed V3. The speed V3 may be greater than the speed V1 or less than the speed V1. However, the speed V2 is a speed greater than the speed V3. In this case, in the constant speed control in S204, the car 1 may be moved at the speed V1, or the car 1 may be moved at the speed V3.
Fig. 12 is a flowchart showing another operation example of the elevator apparatus according to embodiment 1. Fig. 12 shows an example of the operation of the control device 8 when the gear shift control is performed in S203.
When the gear shift control is started in S203, the abnormality detection unit 44 determines whether or not an abnormality has occurred in the detected position detected by the position detection unit 43 (S601). As described above, the position detecting unit 43 detects the position P of the car 1 based on the signal from the encoder 7, for example.
On the other hand, when the car 1 passes a landing 30, the floor 29 provided in accordance with the height of the landing 30 is detected by the floor stopping device 17. The abnormality detection unit 44 determines in S601 based on the position P of the car 1 detected by the position detection unit 43 when the landing device 17 detects the plate 29. For example, when the floor-stopping device 17 detects a certain plate 29, the position P detected by the position detecting unit 43 should ideally always show the same value. When the deviation between this value and the position P detected by the position detecting unit 43 exceeds the allowable range, the abnormality detecting unit 44 determines yes in S601. If the deviation between the value and the position P detected by the position detecting unit 43 does not exceed the allowable range, the abnormality detecting unit 44 determines no in S601.
When the abnormality detection unit 44 detects an abnormality (yes in S601), the operation control unit 41 ends the speed change control and starts the constant speed control (S602). That is, even when the start condition is satisfied and the car 1 is in the area A2, the operation control portion 41 moves the car 1 at the speed V1 in accordance with the operation of the operation button 32. If the abnormality detection unit 44 does not detect an abnormality (no in S601), the operation control unit 41 continues the shift control (S603).
In the example shown in fig. 12, the floor stopping device 17 is an example of a means for detecting that the car 1 is disposed at a specific position. Instead of the landing gear 17, the elevator apparatus may also be provided with other detection means. The position at which the detection means detects the arrangement of the car 1 may not match the height of the landing 30.
