Problems to be solved by the invention
A tailless-type elevator apparatus is equipped with a battery for supplying power to a lighting device and a door drive device provided in a car.
However, the elevator apparatuses described in patent documents 1 and 2 do not particularly consider the battery charge state during maintenance operation.
In a tailless-type elevator apparatus, when a car stops at a stopping floor provided with a power transmitting portion, the power transmitting portion supplies power to the car in a manner opposed to a power receiving portion and charges a battery, but in a maintenance operation, the car does not always stop at the stopping floor provided with the power transmitting portion, and even at the stopping floor provided with the power transmitting portion, the car may be stopped by being deviated from the position of the stopping floor. In these cases, the car cannot receive power supply, and therefore the devices in the car receive power supply from the battery provided in the car.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is an overall schematic diagram of an elevator apparatus according to an embodiment of the present invention. An elevator apparatus 100 includes a car 102 that moves vertically in an elevator shaft 101, a counterweight 103 that moves vertically in the elevator shaft 101 in opposition to the car 102, and a wire rope 104 that connects the car 102 and the counterweight 103, in the elevator shaft 101.
The elevator apparatus 100 includes, in an upper portion thereof: a hoisting machine 105 that winds up the wire rope 104 and moves the car 102 in the vertical direction; a sheave 106 that switches the direction of the wire rope 104; and an elevator control device 107 that controls the equipment of the elevator.
The building in which the elevator apparatus 100 is installed is provided with a stop floor 108 (108 a,108b,108 c) at which the car 102 stops.
The elevator apparatus 100 includes: and a power transmission unit 110 (110 a,110 b) for supplying power to the car 102 via the power line 109 when the car 102 stops at a predetermined stop level 108a,108 c. The stop layers 108a and 108c provided with the power transmitting portions 110a and 110b are referred to as power suppliable layers. The power feedable layers ( stop layers 108a and 108 c) provided with the power feeding unit 110 are, for example, any positions of 1, 10, and 20 floors of a building. When the electricity suppliable floor is provided, the floor is preferably a floor where the number of times the car stops is large.
The car 102 is provided with a power receiving unit 111 in an upper portion thereof, which receives electric power from the power transmitting unit 110 (110 a,110 b) when the car 102 stops at the stopping floors 108a,108 c. The power receiving unit 111 receives electric power by facing the power transmitting unit 110 (110 a,110 b). In the power transmission unit 110 and the power reception unit 111, electric power is transmitted from the power transmission unit 110 to the power reception unit 111 by, for example, electromagnetic induction. Further, a battery 112 that charges a part of the electric power received by the power receiving unit 111 is provided in an upper portion of the car 102. The elevator apparatus 100 includes a signal line 113 for detecting the state of the power transmission unit 110 (110 a,110 b).
In normal operation of the elevator apparatus 100, the car 102 stops at the positions of the respective stopping floors 108a,108b, and 108 c. When the car 102 stops at the stopping floors 108a and 108c, the power transmission unit 110 (110 a and 110 b) faces the power receiving unit 111, and the power receiving unit 111 receives electric power from the power transmission unit 110 (110 a and 110 b). The electric power received by power receiving unit 111 is charged in battery 112.
Maintenance such as inspection and component replacement is performed in the elevator apparatus 100. When maintenance is performed, the operation mode is switched from the normal operation mode to the maintenance operation mode. In the maintenance operation mode, as shown by a broken line in fig. 1, there is a case where the car 102' stops at a position deviated from the stopping floor 108 c. In this state, since power transmission unit 110b and power reception unit 111 are not opposed to each other, power reception unit 111 cannot receive electric power and performs maintenance work exclusively with electric power charged in battery 112. When the charge amount of the battery 112 is insufficient, the operation of the equipment in the maintenance work cannot be performed, and the maintenance work has to be interrupted. A method for preventing this will be described below.
Fig. 2 is a block diagram showing the structure of an elevator control device according to an embodiment of the present invention. In fig. 2, the elevator control device 107 includes: a maintenance signal transmitting unit 201 that transmits a maintenance signal by an operation of a maintenance worker; a maintenance signal receiving unit 202 that receives the maintenance signal from the maintenance signal transmitting unit 201; an elevator state monitoring unit 203 for monitoring various states of the elevator; a battery state diagnosis unit 204 that diagnoses the state of the battery 112 mounted on the car 102; a power suppliable floor determination unit 205 that moves the car 102 to the stop floors 108a and 108c on which the power transmission units 110 (110 a and 110 b) are provided, based on the diagnosis by the battery state diagnosis unit 204; a door opening/closing/broadcasting control unit 206 that controls control and guidance broadcasting related to the opening and closing of the doors of the car 102; a charge control unit 207 that controls charging of the battery 112 mounted on the car 102 at a power suppliable floor; a charging state determination unit 208 that determines the charging state of the battery 112 and performs a determination of switching from the normal operation mode to the maintenance operation mode in a state where the car 102 is stopped at the stopping floors 108a and 108c where the power transmission units 110 (110 a and 110 b) are provided; a storage unit 209 in which a maintenance operation mode switching program and the like are stored; and a control unit 210 for controlling each unit based on the maintenance operation mode switching program.
The battery state diagnosing unit 204 determines whether the battery 112 can be switched to the maintenance operation mode when the maintenance signal is detected. When the battery state diagnosis unit 204 determines that the battery 112 is not in a state in which it can be switched to the maintenance operation mode, the power suppliable floor determination unit 205 moves the car 102 to the stop floors 108a and 108c on which the power transmission units 110 (110 a and 110 b) are provided.
Fig. 3 is a flowchart showing a processing operation of an elevator apparatus according to an embodiment of the present invention.
In step S301, when the maintenance worker performs an operation of transmitting a mechanical maintenance signal by a switching operation of the mechanical switch or a soft maintenance signal for switching by a maintenance tool in order to switch from the normal operation mode to the maintenance operation mode, a signal is transmitted from the maintenance signal transmitting unit 201 to the maintenance signal receiving unit 202. Upon receiving the signal, the maintenance signal receiving unit 202 supplies an operation signal to the battery state diagnosing unit 204 while using various signals held by the elevator state monitoring unit 203.
In step S302, the battery state diagnosis unit 204 determines whether or not the battery 112 mounted on the car 102 is in a battery state that can be switched to the maintenance operation mode. As a result, if the battery state is a battery state in which the maintenance operation mode can be switched (yes in step S302), the process proceeds to step S309, and the maintenance operation mode is immediately switched.
If the battery state diagnosis unit 204 determines in step S302 that the battery state is not a battery state that can be switched to the maintenance operation mode (no in step S302), it starts preparation for moving the car 102 to the power suppliable floor (the stop floors 108a and 108 c) for charging the battery. At this time, in order not to cause the closing by the passenger entering the car 102, the elevator control device 107 includes a door closing completion detection unit (not shown) of the car 102, and detects the open/closed state of the door.
When the door closing completion detection unit detects that the car 102 of the elevator is stopped in step S303 (yes in step S303), the power suppliable floor determination unit 205 determines the nearest power suppliable floor (the landing 108a or the landing 108 c) using the current position data and the power suppliable floor data based on the information from the elevator state monitoring unit 203 in step S304.
When the car 102 is moved to the power suppliable floor (the stopping floor 108a or the stopping floor 108 c), in step S305, a normal operation mode determination unit (not shown) determines whether or not the operation in the normal operation mode is possible. The normal operation mode refers to a mode in which the elevator is operated in a state where no trouble occurs.
In step S306, if the elevator can move in the normal operation mode, the door opening/closing/broadcasting control unit 206 guides the elevator to be separated from the car 102. The door opening/closing/broadcasting control unit 206 notifies passengers of immediate departure from the car 102 by sound or the like in order to avoid passengers remaining in the car 102.
After the car movement guidance is performed by the door opening/closing/broadcasting control unit 206, the car 102 is moved to the determined power suppliable floor in a high-speed operation in step S307.
Charging of the battery is started by the charging control section 207 in the power suppliable layer (the stop layer 108a or the stop layer 108 c), and the state of charge is monitored. Then, in step S308, charge control unit 207 determines whether or not the battery is in a charged state equal to or higher than a predetermined value within a predetermined time period, for example, and switches to the maintenance operation mode. As a result, if the state of charge of the battery is good (yes in step S308), the mode is switched to the maintenance operation mode in step S309.
As described above, in the present embodiment, when the elevator control device 107 receives the switching signal to the maintenance operation mode, the battery state diagnosis unit 204 temporarily determines whether or not the battery 112 mounted on the car 102 is in the battery state in which the switching to the maintenance operation mode is possible, instead of immediately switching. In this embodiment, even when the battery state is not ideal due to a small amount of charge of the battery, the car 102 is moved to the power suppliable floor (the stop floor 108a or the stop floor 108 c) and can be switched to the maintenance operation mode after charging the battery 112 when the battery state diagnosis unit 204 determines that the battery state is not ideal.
According to the present embodiment, an efficient maintenance operation method can be realized, and the maintenance workability can be improved. In addition, since the determination by the battery state diagnostic unit 204 is performed as early as possible, if the battery state is good, the operation can be directly shifted to the maintenance operation mode.
On the other hand, when the door closing completion detection unit determines in step S303 that the door closing is not completed, it is determined in step S310 whether or not the switching to the maintenance operation mode based on the soft maintenance signal is possible. This is because, in the case of maintenance based on a soft signal, the situation inside the car 102 cannot be confirmed, and therefore, in the case of a passenger riding, the maintenance based on a soft signal is not accepted in the state where the door is opened in order to prevent the passenger from being trapped inside the car 102. When the switching of the maintenance operation mode by the soft signal is accepted in step S310 (yes in step S310), the soft signal is reset in step S312 and the operation is terminated.
In contrast, when the door closing completion detection unit determines that the door is not maintained by the soft signal but the door is opened by another factor in step S310, the door opening/closing/broadcasting control unit 206 performs the door closing operation after performing the door closing guide in step S311 in order to prevent the occurrence of the closure in the car 102. Then, the process returns to step S303, and the door closing completion detection unit monitors the completion of door closing.
If it is determined in step S305 that the elevator is not in the normal operation mode (no in step S305), the normal operation mode determination unit determines in step S313 whether the elevator can be started. As a result, when the elevator can be started (yes in step S313), the door opening/closing/broadcast control unit 206 guides the movement of the car 102 in step S314, and then moves the car 102 to the electricity suppliable floor by the low-speed operation in step S315. That is, the normal operation mode determination unit determines in step S313 that the state is a state in which the car is stopped due to some failure other than the normal operation mode and is not a failure of an important part, and moves the car 102 to the power suppliable floor by the low-speed operation.
However, if the normal operation mode determination unit determines in step S313 that the elevator cannot be started because of, for example, a failure of an important part (no in step S313), the normal operation mode determination unit switches to the maintenance operation mode in step S309.
In this way, since the determination by the normal operation mode determination unit is performed in step S305, the car 102 can be moved to the electricity suppliable floor in the high-speed operation, or the car 102 can be moved to the electricity suppliable floor in the low-speed operation, or the maintenance operation mode can be switched without moving to the electricity suppliable floor, and effective selection can be performed according to the situation.
Further, when the state of charge does not become equal to or greater than the predetermined value within the predetermined time period set in advance in step S308 (no in step S308), the maintenance person cannot move the car 102, but the mode is a mode that does not respond to a normal call, and therefore, the charging is continued in the maintenance standby mode in step S316.
As described above, in the conventional trailing-cable-less elevator apparatus, when the maintenance operation mode is switched, the monitoring or charging of the battery charge state is not particularly taken into consideration, but in the present embodiment, the battery state diagnosis unit 204 that diagnoses the state of the battery 112 in step S302 is added. Therefore, the maintenance operation mode is not immediately switched to when the battery state is not ideal, but the battery state diagnosis unit 204 determines the acceptability, and the battery state diagnosis unit can be switched to the maintenance operation mode after moving to the chargeable layer to charge the battery 112 when the battery state is not ideal.
In addition, since the door closing completion detection unit monitors the door closing in step S303, it is possible to realize an efficient maintenance operation method while preventing the maintenance worker from being closed.
In a tail cable in a long-stroke elevator apparatus, the load on the system increases due to an increase in the weight of a machine shaft due to an increase in the mass, a countermeasure against the loss of control of the cable, and the like. Therefore, the signal transmission and reception between the elevator control device 107 and the car 102 is performed by wireless communication, and the car 102 is provided with a battery and a charging means for supplying power to the equipment of the car 102, and the power supply device provided on the power suppliable floor is used to perform charging in a non-contact manner during a stop and to operate the elevator device, thereby enabling the tail cable itself to be cut down.
However, although a restriction is generated in the maintenance operation mode depending on the battery state, this problem can be solved as described above.
Further, since the car is controlled by the door opening/closing/broadcasting control unit 206 before moving to the power suppliable floor, it is possible to easily prevent an accidental closure by the conventional guidance broadcasting.
In the present embodiment, the battery state diagnosing unit 204 for diagnosing the state of the battery mounted on the car is provided, and the battery state diagnosing unit 204 confirms the battery state when switching to the maintenance operation mode, but the battery capacity may be transmitted to the elevator state monitoring unit 203 side at appropriate intervals to be monitored, and the monitoring result may be taken out and determined at the timing when switching to the maintenance operation mode.
In short, according to the above-described tailless cable elevator apparatus, the battery state diagnosing unit 204 allows or restricts switching to the maintenance operation mode, thereby preventing the maintenance worker from being closed and the efficiency from being lowered.
Further, since the determination by the battery state diagnosis unit 204 is performed in step S302, even when the state of charge of the battery 112 is insufficient, switching to the maintenance operation mode can be permitted in the operation floor and convenience can be maintained as long as the operation is performed only 1 time from the power suppliable floor, for 10 minutes or less, or the like within the predetermined conditions. Further, when the floor operated in the maintenance operation mode is other than the electricity suppliable floor, the maintenance operation mode can be switched to after the floor is moved to the electricity suppliable floor, and thus, the maintenance efficiency can be prevented from being lowered. However, if the battery state of charge is not appropriate, there is a possibility of a failure that the state cannot be started, and therefore if the state is a failure that cannot be started, the operation level is switched to the maintenance operation mode.
As described above, the present invention is characterized by comprising: a battery state diagnosis unit 204 that determines whether or not the battery state is a battery state that can be switched to the maintenance operation mode when the maintenance signal is detected, and switches to the maintenance operation mode; a power suppliable floor determination unit 205 that moves the car to the power suppliable floor when the battery state diagnosis unit 204 determines that the battery state is not a battery state that can be switched to the maintenance operation mode; and a charge state determination unit 208 that determines the state of charge of the power suppliable layer by the power suppliable layer determination unit 205 and determines to switch to the maintenance operation mode.
With this configuration, the battery state diagnosing unit 204 determines the state of the battery, rather than immediately switching to the maintenance operation mode in a state where the battery state is not ideal, and can move to the power suppliable layer to supply power and then switch to the maintenance operation mode in a state where the battery state is not ideal.
In addition to the above configuration, the battery state diagnosing unit 204 may further include a normal operation mode determining unit that determines whether or not the battery state is the normal operation mode when it is determined that the battery state is not the battery state that can be switched to the maintenance operation mode.
With this configuration, it is possible to determine whether or not to move the car to the power suppliable layer in a high-speed operation or to move the car to the power suppliable layer in a low-speed operation.
The present invention is not limited to the above-described embodiments, and various modifications are possible. For example, the above-described embodiments are examples explained in detail to explain the present invention easily and understandably, and are not limited to having all the structures explained. In addition, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. In addition, a part of the configuration of each embodiment can be added, deleted, or replaced with another configuration.
