Abstract
The car has: a battery for storing electric power supplied to equipment used in the car; and a power receiving unit for receiving power supplied from a power supply unit provided at a power supply floor of the hoistway and charging the battery. An elevator control device is provided with: a comparison unit that compares a remaining power level of the electric power stored in the battery with a preset determination value; and a power supply unit that reduces the amount of power supplied to the device when the remaining power level is equal to or less than the determination value.
Description
Technical Field
The present invention relates to an elevator and an elevator control device.
Background
In the conventional car, power is supplied through a tail wire connecting a power supply in the hoistway and the car, and thereby devices (in-car lighting, an air conditioner, and the like) in the car operate. However, if the car is servicing in a long trip, the weight of the tail wire affects the movement of the car. Thus, an elevator apparatus is provided that does not require a tail wire. In such an elevator apparatus, devices in the car are operated by electric power supplied from a battery provided in the car. When the remaining power of the battery is reduced, the car stops at the power supply floor in the hoistway, and the battery is charged in a non-contact manner from a power supply device provided at the power supply floor. A method in which such a power supply device supplies power to the battery in a non-contact manner is referred to as "non-contact power supply".

Disclosure of Invention
Problems to be solved by the invention
However, the remaining amount of electric power of the battery provided to the car decreases as the car travels. However, the power capacity of the battery provided in the car is not large, and the number of times of supplying power to the battery becomes frequent. If the car can be immediately moved to the power supply floor, the battery can be charged, but since the use frequency of the car is high in a congested time period (for example, at work, lunch, and work), it is difficult to continuously stop the car at the power supply floor.
Further, patent document 1 discloses a control system for group management of a plurality of machines. However, in the technique disclosed in patent document 1, if the elevator is not an elevator including a plurality of elevators, it is not possible to move a car in which a battery that needs to be charged is installed to a power supply floor and supply power. However, in an elevator in which only 1 car is installed, the car frequently moves in a time zone in which the number of users riding in the car is large, for example. If the remaining power of the battery is excessively reduced, for example, the illumination of the illumination unit is interrupted. In order to avoid such a situation, the car must be moved to the power supply floor to charge the battery regardless of the presence or absence of the user, and thus sufficient service cannot be provided to the user.
The present invention has been made in view of such a situation, and an object thereof is to balance power supply to a battery mounted on a car and provision of a service to a user.
Means for solving the problems
An elevator according to the present invention includes a car that moves in an elevator shaft and an elevator control device that controls the operation of the car. The car has: a power storage unit that stores electric power to be supplied to a device used in the car; and a power receiving unit that receives electric power supplied from a power supply unit provided at a power supply floor of the hoistway and charges the power storage unit.
An elevator control device is provided with: a comparison unit that compares a remaining power level of the electric power stored in the storage unit with a predetermined determination value; and a power supply unit that reduces the amount of power supplied to the device when the remaining power level is equal to or less than the determination value.
Effects of the invention
According to the present invention, since the amount of power supplied to the equipment is reduced according to the remaining power amount, the number of times of power supply can be reduced, and for example, even in a time zone in which the number of users riding in the car is large, it is possible to continue providing services to the users.
Problems, structures, and effects other than those described above will be apparent from the following description of the embodiments.

Detailed Description
Hereinafter, the present embodiment will be described with reference to the drawings. In the present specification and the drawings, the same reference numerals are given to components having substantially the same function or configuration, and redundant description is omitted.
[ one embodiment ]
Fig. 1 is an explanatory diagram showing an example of a schematic configuration of an elevator.
The elevator 1 includes an elevator control device 3, an elevator shaft 5 formed in a building, a hoisting machine 4, a car 10 on which a user rides, a counterweight 11, and a main rope 12 wound around the hoisting machine 4 and suspending the car 10 and the counterweight 11.
The hoistway 5 is formed in a building, and a machine room 2 is provided on the top thereof. The hoisting machine 4 is disposed in the machine room 2, and is rotated in a normal direction or a reverse direction by a motor not shown, and the car 10 is lifted and lowered in the hoistway 5 by winding the main rope 12. The car 10 is guided by the guide rail 7 extending in the z direction and ascends and descends in the z direction. In fig. 1, one guide rail 7 is shown, but two or more guide rails 7 may be provided. The hoisting machine 4 is provided with an encoder 4a, and the encoder 4a is directly connected to a motor, not shown, to generate a pulse proportional to the speed of the motor.
The elevator control device 3 is provided in the machine room 2. The elevator control device 3 analyzes information (pulse signal) transmitted from the encoder 4a of the elevator 1 or controls the operation of the car 10. The elevator control device 3 increases or decreases the electric power supplied to the equipment used in the car 10. The devices used in the car 10 include, for example, an illumination portion 24, an air conditioning portion 25, a display portion 26, and a car door 27.
The hoistway 5 is a hoistway for a plurality of floors, and the car 10 stops at a stop level (elevator hall) indicating a stop position of each floor according to a destination floor. The support body 6 is a wall, a column, a guide rail, or the like that supports the hoistway 5 of the car 10. The coil unit 8 is used as an example of a power supply unit that performs power transmission of non-contact power supply, and is fixed to the support body 6 directly or indirectly via another object. The coil unit 8 is installed inside the hoistway 5 having, as power supply floors, 1 floor or the uppermost floor (viewing floor) where many users are located. In fig. 1, an example in which the coil units 8 are provided in 1 layer is shown.
A power receiving portion 21 and a battery 22 are provided in a lower portion of the floor of the car 10. The power receiving unit 21 receives the electric power supplied from the coil unit 8 and charges the battery 22. The power receiving unit 21 includes a coil unit 21a and a charging circuit 21 b. The coil unit 21a receives electric power transmitted from the coil unit 8. The charging circuit 21b charges the battery 22 with the electric power received by the coil unit 21 a.
The battery 22 is used as an example of a power storage unit that stores electric power to be supplied to equipment used in the car 10. As the battery 22, for example, a capacitor, a lead storage battery, a lithium ion battery, or the like is used.
A ceiling portion of the car 10 is provided with an illumination portion 24 and an air conditioning portion 25. The illumination unit 24 is, for example, ceiling illumination such as an LED (Light Emitting Diode) for illuminating the inside of the car 10. The air conditioner 25 is a fan or the like that adjusts the temperature in the car 10.
A display unit 26 and a car door 27 are provided on a side surface of the car 10. The display unit 26 is a liquid crystal screen for displaying the destination floor of the car 10, the opening/closing state of the car door 27, and the like. The car doors 27 are opened and closed together with elevator hall doors, not shown, at the floor where the car 10 stops.
The coil unit 21a can perform data communication with the elevator control device 3 by wireless communication. Further, the elevator control device 3 can perform data communication with the coil unit 8 by wired communication or wireless communication. The elevator control device 3 is connected to an elevator monitoring device, not shown, that monitors the state of the elevator 1 via a communication line.
The position P0 indicates a position in the z direction of the central axis of the coil in the coil unit 21a mounted on the car 10. The position P1 indicates a position in the z direction of the center axis of the coil in the coil unit 8 provided in the elevator hall of level 1. When the car 10 reaches the power supply position, i.e., the position P1 and stops (P0)
P1), the coil unit 8 starts power feeding. Coil unit 21a receives electric power from coil unit 8, and charging circuit 21b charges battery 22 with the electric power received by coil unit 21 a.
Fig. 2 is a functional block diagram showing a configuration example of the elevator control device 3. In fig. 2, solid arrows indicate the flow of data, and dashed arrows indicate electric power supplied to devices (including the illumination unit 24, the air conditioning unit 25, the display unit 26, and the car door 27) used in the car 10.
The elevator control device 3 includes a comparison unit 31, a power supply unit 32, a determination value storage unit 33, a determination value change unit 34, and an operation control unit 35.
The comparison unit 31 compares the remaining power level of the electric power stored in the battery 22 (hereinafter, referred to as "remaining battery level") with the first determination value and the second determination value set in advance in the determination value storage unit 33, and outputs the comparison result to the electric power supply unit 32. The second determination value is lower than the first determination value.
The power supply unit 32 reduces the amount of power supplied from the battery 22 to the devices used in the car 10 based on the comparison result input from the comparison unit 31, and supplies power to the devices used in the car 10. The case of reducing the amount of electric power supplied to the devices used in the car 10 is the case where the remaining battery level is equal to or less than the first determination value or the first determination value and the second determination value.
The determination value storage unit 33 stores a first determination value and a second determination value as the determination values to be referred to by the comparison unit 31. The first determination value and the second determination value are appropriately read from the determination value storage unit 33 by the power supply unit 32, and are used for comparison with the remaining battery level.
The determination value changing unit 34 changes the first determination value and the second determination value set in the determination value storage unit 33 to increase or decrease in accordance with the operation state of the car 10 supplied from the operation control unit 35 or a time period including the operation time of the car 10. The determination value changing unit 34 changes to increase the first determination value and the second determination value when the average value of the remaining power amounts in a predetermined period in the past (for example, 1 hour in the past from the present time) is equal to or less than the current first determination value. The determination value changing unit 34 changes to decrease the first determination value and the second determination value when the average value of the remaining power amounts in a predetermined period in the past (for example, 1 hour in the past from the current time) exceeds the current first determination value.
The operation control unit 35 controls the operation of the devices used in the car 10, and acquires the operating conditions of the devices. The operation control unit 35 controls the operation of the car 10 and notifies the comparison unit 31 of the operation state of the car 10. Further, the operation control unit 35 receives the state of charge to the battery 22 from the coil unit 21 a. The operation control unit 35 controls the operation of the hoisting machine 4, and causes the hoisting machine 4 to hoist the main rope and move the car 10 in the hoistway 5. Then, the operation control unit 35 analyzes the information transmitted from the encoder 4a, and confirms the current position of the car 10.
When the car 10 reaches the electricity supply floor, the operation control unit 35 extends the open time of the car doors 27 to be longer than the open time of the car doors 27 when the car stops at a floor other than the electricity supply floor. This lengthens the time for which the car 10 stops at the power supply floor, and the power receiving unit 21 receives the electric power transmitted from the coil unit 8. As a result, the time for which power receiving unit 21 charges battery 22 becomes longer, and sufficient power can be charged into battery 22.
Fig. 3 is a block diagram showing an example of a hardware configuration of the computer C constituting the elevator control device 3.
The computer C is hardware used as a so-called computer. The computer C includes a CPU (Central Processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (Random Access Memory) C3, which are connected to a bus C4, respectively. The computer C further includes a nonvolatile storage device C5 and a network interface C6.
The CPU C1 reads out and executes the program codes of the software that realizes the functions according to the present embodiment from the ROM C2. Variables, parameters, and the like generated during the arithmetic processing are temporarily written in the RAM C3.
Examples of the nonvolatile storage device C5 include a Hard Disk Drive (HDD), a Solid State Drive (SSD), a flexible Disk, an optical Disk, a magneto-optical Disk, a CD-ROM, a CD-R, a magnetic tape, and a nonvolatile memory. In addition to an OS (Operating System) and various parameters, a program for causing the elevator control device 3 to function is recorded in the nonvolatile storage device C5. ROM C2 and nonvolatile storage device C5 record programs, data, and the like necessary for CPUC1 to operate, and are used as an example of a computer-readable non-transitory recording medium in which programs executed by elevator control device 3 are stored.
For the Network Interface C6, for example, an NIC (Network Interface Card) or the like is used, and various data can be transmitted and received between devices via a LAN (Local Area Network) or a dedicated line to which a terminal is connected.
Fig. 4 is an explanatory diagram showing an example of the storage capacity of the battery 22 and the current battery residual capacity. For example, when the storage capacity of battery 22 is set to 100%, power receiving unit 21 shown in fig. 1 can charge battery 22 to 100% at maximum.
In fig. 4, the remaining battery level is indicated by hatching. For example, the current battery remaining level is set to 80% of the storage capacity. Note that 50% of the storage capacity is set as the first determination value, and 30% of the storage capacity is set as the second determination value. Since the remaining battery level is sufficient if the remaining battery level is 80% of the storage capacity, the electric power that is normally used is supplied from the electric power supply unit 32 to the devices used in the car 10.
However, when the battery remaining power is 50% or less of the storage capacity, the amount of electric power supplied to the illumination unit 24 and the display unit 26 is reduced by the electric power supply unit 32. Therefore, the illumination portion 24 illuminates the interior of the car 10 at a lower brightness than that in normal use. The display unit 26 displays guidance of a destination floor or the like at a lower brightness than that in normal use. Even if the amount of electric power supplied to the illumination portion 24 and the display portion 26 is reduced in this way, the comfort for the user riding in the car 10 is not significantly reduced.
Further, when the battery remaining power is 30% or less of the storage capacity, the electric power supply unit 32 reduces the amount of electric power supplied to the air conditioner unit 25. At this time, the fan of the air conditioner 25 is stopped. Even if the amount of electric power supplied to the air conditioner 25 is reduced in this way, the comfort of the user riding in the car 10 is not significantly reduced.
As described above, the first determination value and the second determination value are changed by the determination value changing unit 34 according to the time period in which the car 10 is operated, the operation state in the building in which the car 10 is installed, and the like. For example, if the time period in which the car 10 is running is a normally used time period, the first determination value and the second determination value are maintained at the initial values (the first determination value is 50%, and the second determination value is 30%). However, if the user is in a late night when the user is not seated, the determination value changing unit 34 changes the first determination value and the second determination value to values lower than the initial values. Therefore, the remaining battery level is less likely to fall below the first determination value and the second determination value, and the number of times the car 10 moves to the power supply floor can be reduced.
On the other hand, if the time period in which the car 10 travels is a congested time period, the time in which the car 10 stops at the power supply floor becomes short, and therefore the remaining battery capacity is likely to decrease. Therefore, the determination value changing unit 34 changes the first determination value and the second determination value to values higher than the initial values. Therefore, if the remaining battery level is lower than the first determination value and the second determination value that are changed, the amount of electric power supplied to the equipment used in the car 10 immediately decreases. This can reduce the number of times the car 10 moves to the power supply floor even in a congested time zone.
< example of processing of Elevator control device >
Next, a processing example of the elevator control device 3 will be described with reference to fig. 5 to 7.
Fig. 5 is a flowchart showing an example of processing for controlling the amount of electric power supplied to the devices used in the car 10.
First, the comparison unit 31 determines whether or not the battery residual quantity is 50% or less of the storage capacity (S1). When it is determined that the remaining battery level is not 50% or less of the storage capacity (no at S1), the present process is terminated because the remaining battery level is sufficient.
When it is determined that the battery remaining level is 50% or less of the storage capacity (yes at S1), the power supply unit 32 reduces the power supplied to the illumination unit 24 and the display unit 26. At this time, for example, the brightness of the LEDs of the illumination unit 24 and the liquid crystal screen of the display unit 26 decreases (S2).
Next, the comparing unit 31 determines whether or not the battery remaining power is 30% or less of the storage capacity (S3). When it is determined that the remaining battery level is not equal to or less than 30% of the storage capacity (no in S3), the present process is terminated in a state where the brightness of the LEDs of the illumination unit 24 and the liquid crystal screen of the display unit 26 is reduced.
When it is determined that the battery remaining level is 30% or less of the storage capacity (yes at S3), the power supply unit 32 reduces the power supplied to the air conditioner 25. Thereby, the fan of the air conditioner 25 is stopped (S4).
Next, the operation control unit 35 determines whether or not the car 10 is stopped at the power supply floor (S5), and receives the result of comparison of the remaining battery level by the comparison unit 31. By passing through step S3, the operation control unit 35 receives the comparison result indicating that the battery remaining level is determined to be 30% or less of the storage capacity from the comparison unit 31.
When the operation control unit 35 determines that the car 10 is not stopped at the power supply floor (no in S5), it ends the present process. On the other hand, when determining that the car 10 is stopped at the electricity supply floor (yes at S5), the operation control unit 35 extends the time for which the car 10 opens the car doors 27 at the electricity supply floor to be longer than the time for which the car doors 27 are opened when the car 10 is stopped at a floor other than the electricity supply floor (S6). This ensures a long charging time for the battery 22. After that, the present process is ended.
< example of first processing for changing Current determination value >
The operation state of the elevator 1 is changed with time, and the first determination value and the second determination value may be fixed and the remaining battery level may be immediately lower than the first determination value and the second determination value. However, it is necessary to suppress the number of times of charging the battery 22 as much as possible. Therefore, the power supply unit 32 performs the first process of changing the first determination value and the second determination value. An example of the first process in which the power supply unit 32 changes the first determination value and the second determination value will be described below with reference to fig. 6 and 7.
Fig. 6 is a flowchart showing an example of the first process in which the determination value changing unit 34 changes the first determination value and the second determination value.
Fig. 7 is an explanatory diagram showing an example of the average value of the remaining battery power levels and the first determination value and the second determination value that have been changed in the past 1 hour.
First, the determination value changing unit 34 determines whether or not the current time is the congestion time zone (the time of work, the time of lunch, and the time of work) based on the operation data supplied from the operation control unit 35 (S11). When determining that the current time is the congestion time zone (yes at S11), the determination value changing unit 34 changes the first determination value from 50% to 70% and the second determination value from 30% to 50% (S12), and ends the present process. In the congestion time zone, the remaining battery level is likely to decrease, and therefore, in order to suppress the decrease in the remaining battery level as much as possible, control for reducing the amount of electric power supplied to the devices used in the car 10 is performed in advance.
When it is determined in step S11 that the current time is not the congestion time zone (no in S11), the determination value change unit 34 determines whether or not the average value of the remaining battery levels 1 hour after the current time (referred to as "average remaining battery level") is equal to or less than the current determination value (e.g., first determination value) (S13). The current determination value used for the determination at step S13 may be the second determination value.
Fig. 7A shows that the average remaining battery level is 50% or less, which is the current determination value. In fig. 7A, the current determination value is described as "current first determination value". When it is determined that the average remaining battery level is equal to or less than the current determination value (yes at S13), the determination value changing unit 34 adds 10% to the current determination value (S14), and ends the present process. Thereby, the first determination value is changed from 50% to 60%. Further, in accordance with the change of the first determination value, the second determination value may be changed from 30% to 40% by adding 10% to the second determination value. In fig. 7A, the changed first determination value is described as "new first determination value", and the changed second determination value is described as "new second determination value". Since the current determination value is increased in this way, even if the current time is not the congestion time zone, if the current time is an operation state in which the remaining battery level is likely to decrease, the power supplied to the equipment used in the car 10 decreases, and therefore, the decrease in the remaining battery level can be suppressed.
When determining that the average remaining battery level exceeds the current determination value (no at S13), the determination value changing unit 34 subtracts 10% from the current determination value (S15) and ends the present process. In fig. 7B, the average remaining battery level exceeds 50% which is the current determination value. Thereby, the first determination value is changed from 50% to 40%. In addition, the second determination value may be reduced by 10% and changed from 30% to 20% in accordance with the change of the first determination value. In this way, if the current time is not a congestion time period but an operation state in which the remaining battery level is difficult to decrease, the current determination value is lowered, so that the equipment can be maintained in a normally used state for a long time without reducing the power supplied to the equipment used in the car 10.
< example of second processing for changing Current determination value >
Next, an example of the second process of changing the current determination value will be described. In fig. 1, the example in which the power supply floor is provided only at floor 1 is shown, but the power supply floor may be provided at another floor. The more the power supply floors, the longer the number of floors to be charged into the time battery 22 and the longer the charging time when the car 10 is stopped, but the installation cost of the power supply floors also increases. Therefore, the number of floors on which the power supply floors are installed varies from building to building. Therefore, at the time of installation of the elevator 1, the determination value of the number of floors to be installed is changed from the power supply floor to all the floors.
Fig. 8 is a flowchart showing an example of the second process in which the determination value changing unit 34 changes the first determination value and the second determination value. The initial values of the first determination value and the second determination value are set to 50% and 30%, respectively.
First, the determination value changing unit 34 determines whether the ratio of the power supply floor to all floors is high (S21). For example, if 1 power supply floor is provided every 5 floors, two power supply floors are provided if there are 10 floors. In this case, the proportion of the power supply floor is calculated to be 20%. The determination value changing unit 34 sets the power supply floor rate to 20% as a reference value for changing the determination value. The determination value changing unit 34 maintains the first determination value and the second determination value if the ratio of the power supply floors is 20% or more, and changes to decrease the first determination value and the second determination value if the ratio of the power supply floors is less than 20%.
For example, if three power supply floors are installed in a 10-story building, the ratio of the power supply floors is 33%. Therefore, the determination value changing unit 34 determines that the ratio of the power supply floor is 20% or more and the ratio of the power supply floor is high (yes at S21). In this case, the judgment value changing unit 34 keeps the current judgment value stored in advance in the judgment value storage unit 33 unchanged from the initial value (S22), and ends the present process. Therefore, the first determination value is maintained at 50% and the second determination value is maintained at 30%.
For example, if one power supply floor is provided in a 10-story building, the ratio of power supply floors is 10%. Therefore, the determination value changing unit 34 determines that the ratio of the power supply floor is less than 20% and the ratio of the power supply floor is low (no in S21). In this case, the determination value changing unit 34 subtracts 5% from each of the current first determination value and second determination value stored in advance in the determination value storage unit 33 (S23), and ends the present process. In this case, the first determination value is changed to 45%, and the second determination value is changed to 25%. The first determination value and the second determination value that have been changed are stored as initial values in the determination value storage unit 33.
In the elevator 1 according to the embodiment described above, the power supply unit 32 reduces the amount of power to be supplied to the devices used in the car 10 based on the result of the comparison between the current remaining battery level and the determination value by the comparison unit 31. Here, the determination values of the remaining amount of the battery 22 may be set in stages, and the amount of electric power supplied to the device may be changed according to each determination value. For example, when the current remaining battery amount becomes equal to or less than the first determination value, the amount of electric power supplied to the illumination unit 24 and the display unit 26 is reduced, and when the current remaining battery amount becomes equal to or less than the second determination value, the amount of electric power supplied to the air conditioning unit 25 is reduced. Therefore, the reduction in the remaining battery level can be suppressed until the battery 22 is charged. Further, even if the current remaining battery level is reduced, the user riding the car 10 does not feel inconvenience.
The determination value changing unit 34 can change the first determination value and the second determination value according to the operation state of the elevator 1. For example, the determination value changing unit 34 can change as follows: the first determination value and the second determination value are increased if the usage frequency of the elevator 1 is high in a congestion time zone, and the first determination value and the second determination value are decreased if the usage frequency is low in a time zone. In this way, the determination value changing unit 34 can perform an operation of appropriately changing the first determination value and the second determination value according to the learning result by learning the operation state of the elevator 1. Further, since the first determination value and the second determination value are changed to appropriate values, the power supply unit 32 can delay the timing of reducing the amount of power to be supplied to the devices used in the car 10.
The determination value changing unit 34 may change the first determination value and the second determination value set in advance according to the ratio of the power supply floors among all the floors. Therefore, the determination value storage unit 33 can store the appropriate first determination value and second determination value according to the building in which the power supply floor is installed in different situations.
[ modified examples ]
The determination value changed by the determination value changing unit 34 may be only one of the first determination value and the second determination value.
For example, if the remaining battery capacity is charged to 90% or more of the storage capacity, the power supply unit 32 may restore the amount of power of the power supplied to the equipment used in the car 10. Therefore, the brightness of the lighting unit 24 and the display unit 26 is restored, and the fan of the air conditioner 25 also starts to rotate. The amount of electric power supplied to the devices used in the car 10 is kept reduced until the battery 22 is fully charged or the remaining battery capacity is charged to 90% or more of the storage capacity. Therefore, a decrease in the remaining battery level can be suppressed.
The elevator control device 3 may be provided in the car 10. The elevator control device 3 itself may be operated by receiving power supply from the battery 22.
The determination values stored in the determination value storage unit 33 include a first determination value and a second determination value. However, there may be at least one judgment value. Further, three or more determination values may be provided. The power supply unit 32 may change the amount of power supplied to the devices used in the car 10, which are divided into pieces in detail for each determination value, individually.
The present invention is not limited to the above-described embodiments, and it is needless to say that various other application examples and modifications can be made without departing from the gist of the present invention described in the claims.
For example, the above-described embodiments are embodiments in which the configuration of the apparatus is described in detail and specifically for easy understanding of the present invention, and are not limited to embodiments having all of the configurations described. In addition, a part of the structure of the embodiment described herein can be replaced with another structure.
Note that only the control lines and information lines considered necessary for the description are shown, and not all the control lines and information lines are necessarily shown in the product. In practice, it can be said that almost all structures are connected to each other.
