Description

  Embodiments of the present invention relate to an elevator non-contact power supply system that supplies electric power necessary for operation of an elevator in a non-contact manner.

  In recent years, interest in non-contact power supply technology has increased, and it has come to be used in various fields. The non-contact power supply technology mainly uses the principle of electromagnetic induction, and transmits electric power in a non-contact manner by generating an electromotive force by applying an alternating magnetic flux generated in the primary coil to the secondary coil. Technology.

  In an elevator, it is considered to be cordless by supplying power consumed by a car in a contactless manner. In this case, the car is provided with a battery for storing electric power supplied in a non-contact manner. Electric power stored in the battery is used to drive equipment (lighting equipment, doors, etc.) in the car.

  In the above-described elevator, when the remaining amount of the battery decreases during the operation of the car, the battery is charged by performing non-contact power supply at the nearest power supply floor. After charging is complete, return the car to normal operation and answer the hall call. However, if power is supplied at a location away from the hall call registration floor, it may take time to respond to the hall call, and may cause passengers to wait for a long time.

  The problem to be solved by the present invention is to provide an elevator non-contact power feeding system capable of shortening the waiting time by responding to a hall call as soon as possible after the battery is fully charged in an elevator equipped with a battery in the car. That is.

  A contactless power supply system for an elevator according to an embodiment includes a battery in a car, and charges the battery by supplying power to the car in a contactless manner at any of a plurality of power supply floors where power supply devices are installed. .

When the charge amount of the battery is reduced to a certain value or less, the contactless power supply system has the above-mentioned power supply floors depending on whether or not there is a hall call when there are no passengers in the car. Power supply control means for selecting a power supply floor for stopping the car as a power supply destination, and when the battery is charged by moving the car to the power supply floor selected as a power supply destination by the power supply control means and the charging is completed Operation control means for returning the car to normal operation, and the power supply control means, when a hall call is registered, between the current position of the car and the hall call registration floor. Based on the positional relationship, a power supply floor suitable for the hall call response is selected from the power supply floors as a power supply destination.

  Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram illustrating a configuration of a contactless power feeding system for an elevator according to a first embodiment. In the example of FIG. 1, a configuration in which three elevators are group-managed is shown, but the configuration is not limited to this configuration. The elevator referred to here is mainly a passenger car. When there are a plurality of elevators, the elevator is also referred to as “unit”.

  The machine control devices 11a, 11b, and 11c are provided corresponding to the cars 12a, 12b, and 12c of each car (A, B, and C), and drive control of a hoisting machine (not shown) and opening / closing of a door are performed. Control the unit itself including control. The cars 12a, 12b, 12c move up and down in the hoistway by driving a hoisting machine (not shown).

  Hall call registration devices 13, lanterns 14 and chimes 15 are installed at the halls on each floor. The hall call registration device 13 is a device for a passenger to register a hall call at a landing, and has an upward button and a downward button for designating a destination direction (upward / downward). The hall call registration device 13 installed on the top floor has only a downward button, and the hall call registration device 13 installed on the bottom floor has only an upward button.

  The “hall call” is a call signal registered at the landing on each floor, and includes information on the registered floor and the destination direction. On the other hand, the “car call” is a call signal registered in the car room and includes information on the destination floor.

  The lantern 14 has a lighting part that is divided into two upper and lower parts, and notifies the arrival of the cars 12a, 12b, and 12c by lighting the upper or lower lighting part. The chime 15 is linked to the lighting of the lantern 14 and notifies the arrival of the cars 12a, 12b, 12c by the generation of a chime sound.

  In practice, as shown in FIG. 2, lanterns 14a, 14b, 14c and chimes 15a, 15b, 15c are provided for each unit. In the example of FIG. 2, hall call registration devices 13a, 13b, and 13c are provided for each unit, but it is sufficient that there is at least one on each floor. Hall call registration devices 13a, 13b, 13c, lanterns 14a, 14b, 14c and chimes 15a, 15b, 15c are installed in the vicinity of the hold doors 16a, 16b, 16c of each unit.

  When hall call registration is performed by the hall call registration device 13, call information in which two pieces of information of a destination direction (upward / downward) and a registered floor (floor on which a passenger performs a registration operation) is combined into one set is obtained. It is output to the group management control device 20.

  The group management control device 20 is a device that performs group management control on the operation of each car (cars 12a, 12b, 12c). The group management control device 20 includes a call management unit 21, an operation control unit 22, a notification unit 23, and a power supply control unit 24. These are processing units executed by software on a microprocessor, and information can be exchanged between the respective units as shown in FIG.

  In addition, here, for convenience, the call management unit 21, the operation control unit 22, the notification unit 23, and the power supply control unit 24 are all described in the group management control device 20, but it is not always necessary to arrange them in the same device. You may arrange | position to a separate apparatus.

  The call management unit 21 associates and stores the hall call information (destination direction and registered floor) registered by the hall call registration device 13 and the numbered machine (assigned number machine) to which the hall call is assigned in the table 21a.

  The operation control unit 22 selects the most appropriate car to which the hall call is assigned based on the operation information (car position, driving direction, door open / closed state, etc.) of each car and makes the car respond to the registration floor as the assigned car. As an allocation method, a generally known method is used. In general, for example, a method is used in which an evaluation value is obtained based on information such as the position and direction of the car of each car, and the car having the highest evaluation value is assigned as the optimum car.

  When the assigned unit arrives at the registration floor, the notification unit 23 turns on the lighting unit above or below the lantern 14 corresponding to the assigned unit and drives the chime 15 to notify the arrival of the assigned unit.

  The above is the configuration of a general elevator group management system. In the present embodiment, a non-contact power feeding method is applied to the elevator group management system.

  That is, the power feeding devices 31a, 31b, 31c corresponding to each unit are installed in a plurality of places in the hoistway. Each of these power feeding devices 31a, 31b, and 31c feeds required power to the cars 12a, 12b, and 12c of each car in a contactless manner. The installation positions of the power feeding devices 31a, 31b, and 31c are, for example, the lowermost floor (reference floor), the intermediate floor, and the uppermost floor. The floor on which the power feeding devices 31a, 31b, and 31c are installed is referred to as a “power feeding floor”.

  It is preferable to set a floor with high traffic demand as a power supply floor. This is because the number of stops of the car is large, and the timing for supplying power increases there. Further, the power supply floor may be changed for each unit.

  The car 12a, 12b, 12c of each car is provided with power receiving devices 32a, 32b, 32c and batteries 33a, 33b, 33c, respectively. The power receiving device 32a receives electric power fed in a non-contact manner from the power receiving device 32a while facing the power feeding device 31a on the hoistway side, and stores it in the battery 33a. The electric power stored in the battery 33a is used for various devices in the car (for example, lighting devices and door motors).

  The same applies to the power receiving devices 32b and 32c. The power receiving device 32b receives electric power fed in a non-contact manner from the power feeding device 31b while facing the power feeding device 31b on the hoistway side, and stores it in the battery 33b. The power receiving device 32 receives electric power fed in a non-contact manner from the power receiving device 32c while being opposed to the power feeding device 31c on the hoistway side, and stores it in the battery 33c.

  For example, an electromagnetic induction method is used as a non-contact power supply method. The “electromagnetic induction method” is a method of transmitting power to the other coil (power receiving side coil) through the magnetic flux generated when a current is passed through one of the two adjacent coils (power feeding side coil). In addition to this, there are a "radio wave system" that converts current into electromagnetic waves and transmits power through an antenna, and an "electromagnetic field resonance system" that uses the resonance phenomenon of electromagnetic fields. It is not limited.

  The power supply control unit 24 provided in the group management control device 20 manages the state of charge of the batteries 33a, 33b, and 33c of each unit. Specifically, the voltage values of the batteries 33a, 33b, and 33c are acquired from the machine control devices 11a, 11b, and 11c, and the power remaining in the batteries 33a, 33b, and 33c is detected as the charge amount from the respective voltage values. .

  Here, for example, when the charge amount (remaining amount) of the battery 33a of the No. A machine has decreased below a certain value, the power supply control unit 24 determines whether or not there is a hall call when there is no passenger in the car 12a. Accordingly, a power supply floor that stops the car 12a is selected as a power supply destination among the power supply floors. The fixed value is, for example, a charge amount that can make one round trip while stopping at each floor, and is assumed to be, for example, 20% of full charge.

  When the hall call is registered, the power supply control unit 24 is suitable for the response of the hall call from each power supply floor based on the positional relationship between the current position of the car 12a and the hall call registration floor. Select the power supply floor as the power supply destination. When the hall call is not registered, the power supply control unit 24 selects the power supply floor nearest to the car 12a as the power supply destination among the power supply floors.

  The operation control unit 22 moves the car 12a to the power supply floor selected as the power supply destination by the power supply control unit 24, charges the battery 33a, and returns the car 12a to normal operation when charging is completed. “Normal operation” refers to an operation that moves in each floor in response to a call (hall call / car call).

  The same applies to Unit B and Unit C. With respect to Unit B, similar power supply control is performed when the amount of charge (remaining amount) of the battery 33b provided in the car 12b drops below a certain value. As for the No. C machine, the same power supply control is performed when the charge amount (remaining amount) of the battery 33c provided in the car 12c is reduced below a certain value.

  In the example of FIG. 1, the power supply control unit 24 is provided in the group management control device 20, but the power supply control unit 24 may be provided in the machine control devices 11a, 11b, and 11c. In this case, each of the machine control devices 11a, 11b, and 11c manages the charge state of the battery of its own machine, and performs power supply control similar to the above when the charge amount becomes a certain value or less.

  Next, the operation of the first embodiment will be described.

  FIG. 3 is a flowchart showing the operation of the elevator group management system in the first embodiment. The power supply control unit 24 provided in the group management control device 20 manages the state of charge of the batteries 33a, 33b, and 33c of each unit, and when a unit having a battery charge amount equal to or less than a certain value is detected, Use the unit as the power supply.

  However, the timing of supplying power is when there are no passengers in the car of the relevant car. The presence / absence of passengers in the car can be detected from, for example, the registered state of the car call and the car load. That is, when the car call is not registered in the car or when the load is not detected by a load sensor (not shown), it is determined that the car is unmanned.

  In the following, in order to simplify the explanation, explanation will be given focusing on Unit A, but the same applies to the other units (Unit B, Unit C).

  When it is detected that the charge amount of the battery 33a provided in the car 12a of the No. A car has decreased to a certain value (for example, 20% of full charge) or less (Yes in step S100), the power feeding control unit 24 First, it is confirmed whether or not there are passengers in the car 12a (step S101). If there is a passenger in the car 12a (No in step S101), the power supply control unit 24 executes the following processing after dropping the passenger on each floor (after responding to all car calls).

  That is, first, the power supply control unit 24 refers to the table 21a of the call management unit 21 to check whether there is an unanswered hall call assigned to the No. A machine (step S102). If there is no corresponding hall call (No in step S102), the power supply control unit 24 selects a power supply floor closest to the current position of the car 12a from each power supply floor as a power supply destination (step S103). The operation control unit 22 moves the car 12a to the power supply floor selected as the power supply destination, and charges the battery 33a with the power supplied from the power supply device 31a (step S104). When the battery 33a is charged up to the predetermined amount Tc (Yes in Step S105), the operation control unit 22 returns the No. A machine to the normal operation and responds when a new hall call is registered (Step S106).

  The predetermined amount Tc is, for example, about 80% of full charge. Specifically, a power value necessary for reciprocating the car 12a from the lowest floor to the highest floor a predetermined number of times (for example, 30 times) is measured in advance, and the power value is used as a criterion for determining the completion of charging by a predetermined amount Tc. Power is supplied to In addition, when the hall call is not registered, it is possible to wait at the power supply floor, so that full charging may be performed during that time.

  When a hall call is assigned to Unit A (Yes in step S102), the power feeding control unit 24 determines whether the middle of each power feeding floor is based on the positional relationship between the current position of the car 12a and the hall call registration floor. The power supply floor suitable for the hall call response is selected as the power supply destination (step S107).

  Specifically, the power supply control unit 24 selects a power supply destination according to the following conditions (1) to (3).

(1) When there is a power supply floor between the current position of the car and the hall call registration floor, the power supply floor is selected as a power supply destination. However, if there are a plurality of power supply floors between the current position of the car and the hall call registration floor, the power supply floor closest to the hall call registration floor is selected as the power supply destination.

(2) When there is no power supply floor between the current position of the car and the registration floor of the hall call The power supply floor in the direction reversed from the current position of the car (the direction opposite to the registration floor of the hall call) The power supply floor that has passed through the hall call registration floor is compared, and the power supply floor having the shorter total traveling distance to the hall call response floor is selected as the power supply destination.

(3) When the hall call registration floor and the power supply floor are the same floor Select the hall call registration floor as the power supply destination.

  The operation control unit 22 moves the car 12a to the power supply floor selected as the power supply destination and charges the battery 33a (step S108). When the battery 33a is charged to a predetermined amount Tc (Yes in step S109), the operation control unit 22 returns the A-unit to normal operation and responds to a new hall call (step S110).

  If the registered floor of the hall call is the same floor as the power supply floor selected as the power supply destination (Yes in step S111), the operation control unit 22 performs the hall call after the charging of the battery 33a is completed. Is performed (step S113).

  In other words, until the charging of the battery 33a is completed, hall call response processing including arrival notification and door opening operation by driving the lantern 14a and chime 15a is not performed. After the charging is completed, the operation control unit 22 lights the lighting unit above or below the lantern 14a through the notification unit 23 and drives the chime 15a to notify the arrival of the No. A vehicle. The operation control unit 22 drives a door motor (not shown) to open the door (the car door and the hold door).

  Specific examples are shown in FIGS. FIG. 4A is a diagram for explaining an example of condition (1), and FIG. 4B is a diagram for explaining an example of condition (2). FIG. 5 is a diagram for explaining an example of the condition 3.

  Assume that in a 20-story building, the 1st, 10th, and 20th floors are installed on the power supply floor. Now, it is assumed that the charge amount of the battery 33a provided in the car 12a of the No. A car has dropped below a certain value.

  If the hall call is not assigned to Unit A when the car 12a goes down to the power supply floor after all passengers have been lowered on the 12th floor during driving in the downward direction, the power supply floor on the 10th floor is the nearest floor. Selected as a power supply destination.

  Here, when an upward hall call is registered on the second floor and the hall call is assigned to Unit A, power is supplied based on the positional relationship between the current position of the car 12a and the hall call registration floor. The floor is selected. In this case, if there is a power supply floor between the current position of the car 12a and the hall call registration floor, the power supply floor is selected as a power supply destination. In other words, in the example of FIG. 4A, there are 10 power supply floors between the current position of the car 12a (12th floor) and the hall call registration floor (2nd floor). Is selected as the power supply destination.

  If there are a plurality of power supply floors between the current position of the car 12a and the hall call registration floor, the power supply floor closest to the hall call registration floor is selected as the power supply destination. For example, in the example of FIG. 4 (a), if the power supply floor is also installed on the fifth floor in addition to the power supply floor on the tenth floor, the fifth floor closest to the second floor, which is the registered floor of the hall call. Will be selected. In this way, when multiple hall calls are registered, the power supply floor closest to the registered floor of the hall call is set as the power supply destination. However, since the acceleration of the car 12a can be increased and moved to the power supply floor, the hall call can be quickly answered as a result.

  In addition, if there is no power supply floor between the current position of the car 12a and the hall call registration floor, the power supply floor in the direction reversed from the current position of the car (the direction opposite to the hall call registration floor) Of the power supply floors that have passed through the hall call registration floor, the power supply floor having the shorter travel distance to the hall call response floor is selected as the power supply destination.

  For example, as shown in FIG. 4 (b), when the car 12a lowers passengers on the fourth floor and heads to the power supply floor during downward driving, the car 12a travels downward from the fourth floor to the first power supply floor. Compared with the case of going to the 10th floor and going to the 10th floor power supply floor, the power supply floor with the shorter mileage until finally responding to the hall call on the 2nd floor is selected as the power supply destination Is done. In the example of FIG. 4B, since it is closer to the power supply floor on the first floor, after power is supplied on the power supply floor on the first floor, it responds to the hall call on the second floor.

  As described above, when the hall call is registered, the power supply floor that can respond to the hall call earliest is selected according to the positional relationship between the current position of the car 12a and the registered floor of the hall call. Therefore, it is possible to reduce the waiting time of passengers waiting for an elevator on the hall call registration floor.

  When the hall call registration floor and the power supply floor are the same floor, the power supply floor is selected as the power supply destination. For example, as shown in FIG. 5, when a hall call is registered on the first floor and the hall call is assigned to Unit A, the first power supply floor is selected as the power supply destination. In this case, the car 12a charges the battery 33a on the power supply floor on the first floor, but during this time, the arrival of the car 12a is not notified and the door is not opened. This is because if the passenger is notified that the car 12a has arrived, the passenger will be suspicious of being unable to board the car. In the group management system, a display (indicator) is generally not installed at the landings on each floor, so it is impossible to explain to the passenger that the reason why the boarding is not being performed is charging the battery.

  As described above, according to the first embodiment, when the charge amount of the battery provided in the car drops below a certain value, the car is selected by selecting the power supply floor according to the presence / absence of the hall call. The battery can be charged by being moved efficiently.

  That is, if the hall call is not registered, the nearest power supply floor is selected. Therefore, after charging the battery in the immediate vicinity of the car, it is possible to return to normal operation as soon as possible. On the other hand, when a hall call is registered (specifically, when a hall call is assigned to the relevant unit), a power supply floor suitable for the response of the hall call is selected. Therefore, it is possible to promptly respond to the hall call after charging the battery near the hall call registration floor, and to reduce the waiting time of passengers.

  In addition, when hall calls are registered, it is possible to charge without making passengers aware of the arrival of the car by prohibiting the arrival notification and door opening operation until the battery is fully charged. It can be performed.

(Second Embodiment)
Next, a second embodiment will be described.

  In addition to the configuration of the first embodiment described above, the second embodiment includes a response process when a new hall call is generated while the car is moving toward the power supply floor. Since the basic processing flow is the same as that in FIG. 3 in the first embodiment, only the processing differences will be described here.

  FIG. 6 is a flowchart showing the operation of the elevator group management system in the second embodiment. The process shown in this flowchart is executed after step S107 in FIG.

  That is, based on the positional relationship between the current position of the car 12a and the registered floor of the hall call, the power supply floor suitable for the hall call response is selected as the power supply destination, and the car 12a of Unit A is the power supply floor. Suppose you are moving. At this time, when a new hall call is generated on another floor and assigned to Unit A (Yes in step S200), the power supply control unit 24 first operates the direction of the new hall call (upward direction). It is determined whether or not (downward) is the same direction as the current traveling direction of the car 12a (step S201).

  If the driving direction of the new hall call is the same direction as the traveling direction of the car 12a (Yes in step S201), the power supply control unit 24 and the first hall call closest to the registration floor of the new hall call The positional relationship with the power supply floor selected at the time is confirmed (step S202).

  Here, the power supply floor selected at the time of the first hall call is defined as the first power supply floor, and the power supply floor closest to the registered floor of the new hall call is defined as the second power supply floor. If the second power supply floor is in front of the traveling direction of the car 12a than the first power supply floor, that is, if the second power supply floor can arrive earlier (Yes in step S202), power supply is performed. The control unit 24 switches the power supply destination to the second power supply floor (step S203).

  The subsequent steps are the same as steps S108 to S113 in FIG. However, the power supply destination of the car 12a is the second power supply floor, and the battery 33a is charged at the second power supply floor. After charging is completed, the car 12a first responds to a new hall call and then responds to the first hall call.

  In the case of No in steps S200, S201, and S202, the first power supply floor is the power supply destination, and the processes of steps S108 to S113 in FIG. 3 are executed.

A specific example is shown in FIG.
Assume that in a 20-story building, the 1st, 10th, and 20th floors are installed on the power supply floor. It is assumed that the first floor power supply floor is selected by an upward hall call on the first floor, and the car 12a is moving from the 15th floor toward the first floor power supply floor.

  Here, it is assumed that a new hall call is registered on the 9th floor and assigned to Unit A while the car 12a is moving toward the first floor. When the driving direction of this new hall call is the same downward direction as the traveling direction of the car 12a, the power supply floor closest to the new hall call registration floor is searched.

  In the example of FIG. 7, the power supply floor is the 10th floor. The 10th power supply floor (second power supply floor) is present in the traveling direction of the car 12a before the first power supply floor (first power supply floor). In such a case, the power supply destination of the car 12a is switched to the power supply floor on the 10th floor (second power supply floor). As a result, the car 12a first stops at the 10th floor, charges the battery 33a, responds to the hall call on the 9th floor and then responds to the hall call on the 1st floor.

  In the example of FIG. 7, the subsequent operation route of the car 12 a differs depending on the destination floor of the passenger boarding on the ninth floor. That is, if the destination floor of the passenger boarded on the 9th floor is any floor of the 8th to 2nd floors, the car 12a moves downward from the 9th floor to pass the passengers on any of the 8th to 2nd floors. After that, it responds to an upward hall call on the first floor, where it reverses direction. However, if the destination floor of the passenger boarded on the 9th floor is the first floor, the car 12a moves downward from the 9th floor and drops the passenger on the first floor, where the direction is reversed and the upper hall on the second floor Answer the call.

  As described above, according to the second embodiment, when a new hall call is generated while the car is moving toward the power supply floor, the power supply destination is determined based on the relationship between the new hall call and the first hall call. By switching appropriately, it is possible to efficiently respond to each hall call after charging the battery.

(Third embodiment)
Next, a third embodiment will be described.

  In addition to the configuration of the first embodiment, the third embodiment includes a response process when a new hall call is generated during battery charging. Since the basic processing flow is the same as that in FIG. 3 in the first embodiment, only the processing differences will be described here.

  FIG. 8 is a flowchart showing the operation of the elevator group management system in the third embodiment. The process shown in this flowchart is executed after the battery is charged in step S109 in FIG.

  In other words, it is assumed that the battery 33a is being charged on the power supply floor selected when the car 12a of the No. A car is the first hall call. At this time, if a new hall call is generated on another floor and assigned to Unit A (Yes in step S300), the operation control unit 22 firstly operates the driving direction specified by the new hall call. It is determined whether (upward / downward) is the same direction as the current traveling direction of the car 12a (step S301).

  If the direction is the same as the traveling direction of the car 12a (Yes in step S301), the operation control unit 22 confirms the positional relationship between the new hall call registration floor and the first hall call registration floor (step S302). ).

  Here, the registration floor of the first hall call is the first registration floor, and the registration floor of the new hall call is the second registration floor. If the second registered floor is ahead of the traveling direction of the car 12a than the first registered floor, that is, if the second registered floor can arrive earlier (Yes in step S302), driving The control unit 22 switches the first response destination when returning to normal operation to the second registered floor (step S303).

  The subsequent steps are the same as steps S109 to S113 in FIG. However, the first response destination when returning to normal operation is not the first registration floor but the second registration floor. That is, when the normal operation is resumed after the charging of the battery 33a is completed, the car 12a responds to the second registration floor and then responds to the first registration floor.

  If No in steps S300, S301, and S302, the first registration floor, which is the first hall call registration floor, is the first response destination, and the processes in steps S108 to S113 in FIG. 3 are executed. Is done.

A specific example is shown in FIG.
Assume that in a 20-story building, the 1st, 10th, and 20th floors are installed on the power supply floor. It is assumed that the 10th floor power supply floor is selected by the downward hall call on the 7th floor, and the car 12a is charging the battery 33a on the 10th floor power supply floor.

  Here, it is assumed that a new hall call is registered on the 8th floor while the battery 33a is being charged and assigned to the No. A machine. If the driving direction of this new hall call is the same downward direction as the traveling direction of the car 12a, the positional relationship between the new hall call registration floor and the first hall call registration floor is confirmed.

  In the example of FIG. 9, the new hall call registration floor (second registration floor) is the eighth floor, and the car 12a has a higher floor than the seventh floor, which is the first hall call registration floor (first registration floor). Present before the direction of travel. In such a case, the first response destination at the time of return to operation is switched to the new hall call registration floor (second registration floor). Thus, when the car 12a completes charging of the battery 33a and returns to normal operation, it first responds to the hall call on the 8th floor and then responds to the hall call on the 7th floor.

  Thus, according to the third embodiment, when a new hall call occurs during battery charging, the first response destination is appropriately switched from the relationship between the new hall call and the first hall call. After charging the battery, it can respond efficiently to each hall call.

(Fourth embodiment)
Next, a fourth embodiment will be described.

  In addition to the configuration of the first embodiment, the fourth embodiment includes a process of changing the determination criterion for charging completion according to traffic demand. Since the basic processing flow is the same as that in FIG. 3 in the first embodiment, only the processing differences will be described here.

  FIG. 10 is a flowchart showing the operation of the elevator group management system in the fourth embodiment. The process shown in this flowchart is executed when it is determined in step S109 in FIG. 3 that charging is complete.

  That is, the power supply floor suitable for the hall call response is selected as the power supply destination based on the positional relationship between the current position of the car 12a and the registered floor of the hall call, and the car 12a of Unit A moves to that power supply destination. Assume that the battery 33a is being charged. At this time, the operation control unit 22 determines whether there is a busy hour or a busy hour based on the current traffic demand (step S400).

  In detail, for example, since there are many people who use elevators in the morning work hours and night work hours, traffic demand increases. On the other hand, since the number of people who use the elevator is less during the night time, traffic demand is low. Therefore, it is assumed that the traffic demand is learned in advance for each time zone, and it is determined whether it is in a busy time or a quiet time depending on the time zone at that time. As another method, for example, the number of waiting people on each floor is detected by a camera or the like in a predetermined time unit (for example, one hour unit), and the traffic demand is obtained from the average value of the waiting people on each floor per unit time. It may be judged whether there is at times.

  If it is congested (Yes in Step S400), the operation control unit 22 lowers the threshold value, which is a criterion for determining the completion of charging, from the steady state (Step S401). This is because it is necessary to finish charging as soon as possible and to respond to hall calls on each floor when crowded.

  On the other hand, if it is a quiet time (No in step S400), the operation control unit 22 raises the threshold value, which is a determination criterion for completion of charging, higher than the normal time (step S402). This is because there are few hall calls on each floor when it is quiet, and there is no problem even if it takes time to charge. Note that a steady-state threshold value is used when it is not crowded or quiet.

  When the charge amount of the battery 33a is equal to or greater than the threshold value, the operation control unit 22 determines that charging is complete. The subsequent processing is the same as steps S110 to S113 in FIG.

  FIG. 11 is a diagram showing the relationship between the amount of charge of the battery and a threshold value that is a criterion for completion of charging. In addition, although the battery 33a provided in the car 12a of the car A will be described as an example here, the same applies to other car.

  L1 to L4 in the figure indicate charging levels. The order is L1> L2> L3> L4. When the full capacity of the battery 33a is fully charged, for example, L1 is about 90% of full charge, L2 is about 80% of full charge, L3 is about 50% of full charge, and L4 is 20% of full charge. Degree. Among these, L2 is a charge amount at the time of steady, and corresponds to the predetermined amount Tc described above.

  When the hall call is assigned to Unit A and the charge amount (remaining amount) of the battery 33a falls below the L4 level, the car 12a is selected from the positional relationship between the current position and the hall call registration floor. The battery 33a is charged by moving to the power supply floor and supplying power. At that time, the criterion for completion of charging is changed according to traffic demand.

  In other words, when it is congested, the threshold value, which is a criterion for determining completion of charging, is set to a level of L3 that is lower than L2 in a steady state. When the charge amount of the battery 33a reaches the level L3, the operation shifts to the normal operation. On the other hand, when it is quiet, the threshold value, which is a criterion for determining the completion of charging, is set to a level of L1 that is higher than L2 in the steady state. When the charge amount of the battery 33a reaches the level L1, the operation shifts to normal operation.

  If the hall call is not registered (no hall call is assigned to Unit A), the car 12a moves to the nearest power supply floor and supplies power (see steps S102 to S104 in FIG. 3). ). Considering the traffic demand at this time, a threshold value may be appropriately set to determine completion of charging.

  As described above, according to the fourth embodiment, by changing the determination criterion for the completion of charging according to traffic demand, it is possible to return to normal operation early when it is congested and to secure a sufficient amount of charge when it is quiet. be able to.

(Fifth embodiment)
Next, a fifth embodiment will be described.

  In addition to the configuration of the first embodiment, the fifth embodiment includes a process for changing the allocation of hall calls according to the battery charging time. Since the basic processing flow is the same as that in FIG. 3 in the first embodiment, only the processing differences will be described here.

  FIG. 12 is a flowchart showing the operation of the elevator group management system in the fifth embodiment. The process shown in this flowchart is executed after step S102 of FIG.

  That is, when the hall call has already been assigned to Unit A and the battery 33a provided in the car 12a drops below a certain value, the power supply control unit 24 calculates the charging time of the battery 33a ( Step S500). Specifically, the power supply control unit 24 determines the time required for charging from the current charge amount (remaining amount) of the battery 33a to the amount necessary for normal operation (for example, about 80% of full charge). Determined by considering Note that the amount to be charged depends on the above-described determination criterion for completion of charging, and may be appropriately changed according to traffic demand as described in the fourth embodiment.

  Here, when the charge amount of the battery 33a is extremely small, it takes time to charge the battery 33a to the predetermined amount Tc, and during that time, the passengers are kept waiting for a long time on the hall call registration floor. Therefore, when the charging of the battery 33a takes a predetermined time Th or more (Yes in step S501), the power supply control unit 24 requests the operation control unit 22 to change the allocation. As a result, the operation control unit 22 changes the assignment of the hall call assigned to the A car to another car (B car or C car) (step S502).

  The time Th can be arbitrarily set in consideration of the charging capability of the battery 33a. In addition, when a plurality of hall calls are assigned to Unit A, all these hall calls are reassigned to other units.

  When the hall call is removed from Unit A due to the allocation change, the power supply control unit 24 selects the power supply floor closest to the current position of the car 12a as the power supply destination from among the power supply floors (step S503). The subsequent steps are the same as steps S104 to S106 in FIG. 3, and the power supply control unit 24 moves the car 12a to the power supply floor selected as the power supply destination, and receives power from the power supply device 31a to replace the battery 33a. Charge. When the battery 33a is charged to a predetermined amount Tc, the operation control unit 22 returns the No. A machine to normal operation and makes it respond when a new hall call is registered.

A specific example is shown in FIG.
Assume that in a 20-story building, the 1st, 10th, and 20th floors are installed on the power supply floor. It is assumed that the charge amount of the battery 33a provided in the car 12a of the No. A car has dropped below a certain value. Further, at this time, it is assumed that the upward hall call registered on the second floor has been assigned to Unit A.

  If the charging of the battery 33a is completed within the predetermined time Th, the car 12a moves to the power supply floor on the first floor, charges the battery 33a there, and then responds to the hall call on the second floor.

  On the other hand, when the charging of the battery 33a takes a predetermined time Th or more, the hall call on the second floor is reassigned to, for example, Unit B. As a result, the car 12b of Unit B moves to the second floor and responds to the hall call. The car 12a moves to the 10th floor, which is the nearest power supply floor, and charges the battery 33a there.

  As described above, according to the fifth embodiment, by changing the allocation of hall calls according to the battery charging time, when it takes time to charge the battery, using other units to prevent delays in the call response, The amount of charge of the battery can be ensured.

(Sixth embodiment)
Next, a sixth embodiment will be described.

  In the sixth embodiment, a case where contactless power feeding is applied to an elevator system of a single car will be described.

  FIG. 14 is a diagram showing a configuration of an elevator non-contact power feeding system according to the sixth embodiment. In the sixth embodiment, the basic configuration is the same as that in FIG. 1 in the first embodiment, except for the difference in the configuration for one car.

  That is, one car 51 is provided in the hoistway, and moves on each floor by driving a hoisting machine (not shown). A hall call registration device 52, a display 53, and a chime 54 are installed at the halls on each floor. The hall call registration device 52 is a device for a passenger to register a hall call at a landing, and has an upward button and a downward button for designating a destination direction (upward / downward). The display 53 is a so-called “indicator” and displays the current position and driving direction of the car 51. The chime 54 notifies the arrival of the car 51 by the generation of a chime sound.

  As shown in FIG. 15, the hall call registration device 52, the display device 53, and the chime 54 are installed in the vicinity of the hold door 56.

  Here, in the hoistway, power feeding devices 55 are installed at a plurality of locations as devices for realizing non-contact power feeding. The installation position of the power feeding device 55 is, for example, the lowest floor (reference floor), the intermediate floor, the top floor, or the like. The floor on which the power supply device 55 is installed is referred to as a “power supply floor”.

  It is preferable to set a floor with high traffic demand as a power supply floor. This is because the number of stops of the car is large, and the timing for supplying power increases there.

  The car 51 is provided with a power receiving device 56 and a battery 57. The power receiving device 56 receives electric power fed from the power feeding device 55 in a non-contact manner in a state of facing the power feeding device 55 on the hoistway side, and stores it in the battery 57. The electric power stored in the battery 57 is used for various devices in the car (for example, lighting devices and door motors).

  The elevator control device 60 controls the operation of the car 51 based on the hall call registered by the hall call registration device 52. The elevator control device 60 includes a call management unit 61, an operation control unit 62, a notification unit 63, and a power supply control unit 64. These are processing units executed by software on the microprocessor, and information can be exchanged between the respective units as shown in FIG.

  Here, for convenience, the call management unit 61, the operation control unit 62, the notification unit 63, and the power supply control unit 64 are all described as being arranged in the elevator control device 60. However, it is not always necessary to arrange them in the same device. It may be arranged in the apparatus.

  The call manager 61 stores hall call information (destination direction and registered floor) registered by the hall call registration device 52 in the table 61a. The operation control unit 62 performs operation control such as causing the car 51 to respond to the hall call registration floor stored in the table 61a. The notification unit 63 displays the floor and the driving direction in which the car 51 is currently moving or stopped on the display 53, and drives the chime 54 when the car 51 arrives at the registered floor.

  The power supply control unit 64 manages the state of charge of the battery 57 provided in the car 51. Specifically, the power remaining in the battery 57 is detected as the charge amount from the voltage value of the battery 57c.

  Here, when the charge amount (remaining amount) of the battery 57 decreases to a certain value or less, the power supply control unit 64 performs each power supply according to the presence or absence of the hall call when there is no passenger in the car 51. A power supply floor that stops the car 51 in the floor is selected as a power supply destination. As in the first embodiment, the constant value is, for example, a charge amount that allows one round trip while stopping at each floor, and is, for example, 20% of full charge.

  When the hall call is registered, the power supply control unit 64 selects the power supply floor suitable for the hall call response as the power supply destination based on the positional relationship between the current position of the car 51 and the registered floor of the hall call. To do. When the hall call is not registered, the power supply control unit 64 selects the power supply floor nearest to the car 51 among the power supply floors as the power supply destination.

  The operation control unit 62 moves the car 51 to the power supply floor selected as the power supply destination by the power supply control unit 64 to charge the battery 57, and when the charging is completed, returns the car 51 to the normal operation.

  In such a configuration, as in the first embodiment, when the charge amount of the battery 57 provided in the car 51 falls below a certain value, the power supply floor is set according to the presence / absence of the hall call. . That is, if the hall call is not registered, the nearest power supply floor is selected. Therefore, after charging the battery 57 on the power supply floor immediately adjacent to the car 51, it is possible to return to normal operation as soon as possible. On the other hand, if a hall call is registered, a power supply floor suitable for the response of the hall call is selected. Therefore, it is possible to respond quickly to the hall call after charging the battery 57, and to reduce the waiting time of the passengers.

  Also, if the hall call registration floor and the power supply floor are the same, the arrival notification and the door-opening operation are prohibited until the charging of the battery 57 is completed. You can charge on the same floor without being aware of arrival.

  In the single car elevator system, as the car 51 moves, the current position of the car 51 is sequentially displayed on the display 53 of each floor. However, when the car 51 is stopped on the power supply floor for charging the battery 57, the display on the display unit 53 is not updated, so that there is a possibility that the passenger is misunderstood.

  Therefore, as shown in FIG. 16, it is preferable to display the current car position on the display 53 and display a message such as “Please wait for a while”. Even when the hall call registration floor is the same floor as the power supply floor, it is preferable to display the same message because the passenger 51 is suspicious that the car 51 has arrived but does not open.

  In the sixth embodiment, the “corresponding process when a new hall call is generated while the car is moving toward the power supply floor” of the second embodiment described above, or the third embodiment The same applies to “a process for handling a new hall call while the battery is being charged” and “a process for changing the determination criterion for the completion of charging according to traffic demand” in the fourth embodiment. . However, “allocation change” in the fifth embodiment cannot be applied to the single car elevator system according to the sixth embodiment because it is a technique specific to the group management system.

(Application examples)
In each of the above embodiments, the case where the battery runs out when the car is moving in the normal operation mode has been described. However, the present invention can be similarly applied when various operations are performed.

  For example, there is a standby operation. In this case, when the car does not have a call (hall call / car call), the car is moved to a predetermined standby floor and is kept waiting there. In a group management system, it is common to cause each unit to be distributed and waited on different floors. In a single car elevator system, it is common to set the reference floor as a standby floor, and when the car stops without a call (hall call / car call), pull it back to the reference floor and wait. is there.

  In such a standby operation, for example, when the car is on standby in the A floor (standby floor), when the battery charge is below a certain value, the power supply closest to the A floor instead of the nearest power supply floor of the car The floor is selected as the power supply destination, and the car is moved there to charge the battery. After charging the battery, move the car to the A floor and wait. In this way, when the charge amount of the battery is below a certain value, the power supply floor close to the standby floor is selected as the power supply destination, so that it waits earlier than charging at another power supply floor and moving to the standby floor. can do.

  According to at least one embodiment described above, in an elevator equipped with a battery in a passenger car, there is provided a non-contact power feeding system for an elevator that can respond to a hall call as soon as possible after the battery is fully charged and reduce the waiting time. Can be provided.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
