Description

The present invention relates to a non-contact power supply elevator.

With the recent increase in the skyscrapers of buildings, it is necessary to lengthen the elevators installed in the buildings. In a general elevator, power is supplied to the equipment in the car by a feeding line called a tail code suspended from the car. As the length of the elevator increases, the tail cord also becomes longer, so the mass of the tail cord increases, and there is concern that if it exceeds a certain length, it will not be able to withstand its own weight. Therefore, in a long-distance elevator, a configuration without a tail code is desired.

There is a technique disclosed in Patent Document 1 as a method of supplying power to a device in a car without using a tail code.

According to Patent Document 1, when the charge amount of the battery drops below a certain value, the car is stopped in each feeding floor according to the presence or absence of a hall call when there are no passengers in the car. The car is moved to the power supply control means for selecting the power supply floor to be fed as the power supply destination and the power supply floor selected as the power supply destination by the power supply control means to charge the battery, and when the charging is completed, the car is charged. The power supply control means is provided with an operation control means for returning the car to normal operation, and the power supply control means is based on the positional relationship between the current position of the car and the registered floor of the hall call when the hall call is registered. Disclosed is a non-contact power supply system that selects a power supply floor suitable for responding to the hall call from the power supply floors as a power supply destination.

JP-A-2017-57054

With the skyscrapers of buildings mentioned above, elevators that supply power in a non-contact manner require power supply and storage to the car, but power transmission equipment is required to supply power in the entire ascending / descending stroke or on the stop floor. A huge number will be required. In addition, with the skyscraper of the building, there is an elevator that raises and lowers the car in the section including the stop floor (service floor) where passengers can get on and off and the transit floor (non-service floor) where passengers cannot get on and off. ..

However, in Patent Document 1, it is shown that it is preferable to set the power supply floor on the floor where the number of car stops is large, which is self-evident. It is not shown which floor should be set as the power supply floor in the non-contact power supply system of.

Hereinafter, examples of embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In each figure, components having substantially the same function or configuration are designated by the same reference numerals and duplicated description will be omitted.

FIG. 1 is a schematic diagram showing a non-contact power feeding system according to the first embodiment. The arrangement shown in FIG. 1 is merely an example, and may be different as long as the function of the elevator is not impaired.

As shown in FIG. 1, the non-contact power feeding elevator 1 according to the first embodiment has a car 40 that moves up and down the hoistway 45, a counterweight 33 that moves up and down together with the car 40, and one end connected to the car 40 and the other end. Is equipped with a rope 32 connected to a counterweight 33. The car 40 is provided with a door 43 for passengers to get on and off. In the present embodiment, the car 40 is shown as a car that carries passengers, but the present invention is not limited to this, and may be such that only luggage is carried.

The car 40 is guided by the rope 32 by the power of the hoisting machine 31 and moves up and down in the vertical direction of the paper surface. The car 40 is controlled to move up and down in the hoistway 45 by a control device (not shown). The power transmission units 1001, 1015, and 1019 are installed on the 1st floor, 15th floor, and 19th floor, respectively. The same applies to the power cables 1201, 1215, 1219, power supplies 1301, 1315, and 1319, and since the basic functions are the same, only the power transmission unit 1001, the power cable 1201, and the power supply 1301 will be described.

The power transmission unit 1001 is installed on the 1st floor, which is the lobby floor. Further, the power transmission unit 1001 is composed of a coil, an inverter, a capacitor and the like, and converts the electric power supplied from the power supply 1301 into a high frequency to generate a magnetic field.

The upper part of the car 40 is provided with a charge / discharge circuit 21, a power storage device 22, and a power receiving unit 20, and the power receiving unit 20 includes a coil, a capacitor, a rectifier, and the like.

For example, when power is supplied on the 1st floor, the power receiving unit 20 receives a magnetic field from the power transmitting unit 1001 and receives electric power. The charge / discharge circuit 21 supplies the electric power used in the power storage unit 22 and the car 40. The power storage unit 22 is a power storage device such as a lead storage battery, a nickel hydrogen battery, a lithium ion battery, and a capacitor.

The power supply 1301 is a power supply such as AC200V, 400V, or DC. The power cable 1201 is an electric wire for sending electric power, a signal, or the like from the power supply 1301 to the power transmission unit 1001. The control unit 30 controls the hoisting machine 31, the power transmission unit 1001, the power receiving unit 20, and the like.

FIG. 2 is a schematic diagram showing a service floor, a non-service floor, and an installation floor of a power transmission unit of an elevator using the non-contact power supply system according to the first embodiment. The service floor is a floor where passengers can get on and off the car 40, and the non-service floor is a floor where passengers cannot get on and off the car 40.

In this embodiment, the elevator has a low-rise zone 90 composed of a plurality of service floors, a passage zone 94 composed of a plurality of non-service floors, and a high-rise zone 98 composed of a plurality of service floors. , An elevator with a route from B1F (1st basement floor) to 19F will be explained as an example.

The low-rise zone 90 is a floor near the lobby floor such as the 1st floor and the basement. The lobby floor is a building with a lot of people coming and going, such as a theater and a hotel. It is a floor with a hall that doubles as a corridor, waiting room, and drawing room attached to the entrance, and may have a hotel reception desk. Here, it is B1F (1st basement floor) and 1F.

The passage zone 94 is on the 2nd to 14th floors on the floor where the elevator does not stop (sometimes). The 2nd and 14th floors are used for explanation, but the floor does not have to exist. For example, it is a section that passes from the average floor of the building to the height of the ceiling or higher.

The high-rise zone 98 is higher than the passage zone 94, and is on the 15th to 19th floors on the floor where the elevator stops and the service (passengers can get on and off).

The power transmission units 1001, 1015, and 1019 indicate the power transmission units installed on the 1st floor, 15th floor, and 19th floor, respectively, and indicate that the floors can transmit power to the car (power supply floor).

The power transmission unit 1001 is installed on the lobby floor, which has many users. Similarly, the power transmission unit 1019 is installed on the top floor, which is the floor with a view of restaurants and many tourists, or the floor farthest from the lobby floor. In addition, the 17th floor is a floor with a large number of uses excluding the top floor, that is, a floor with a large number of stops.

Next, the procedure for determining the installation floor of the power transmission unit 1015 will be described below.

FIG. 3 is a table showing the priority of setting the power supply floor. First, the table predicts the floors with high stop frequency (high stop frequency).

Column a is the floor where the elevator stops (the floor where passengers can use the elevator).

Column b is the number of stores in a commercial building, the number of households in a residential condominium, and the number of guest rooms in an accommodation facility.

Column c is the estimated number of elevator users, and the number of guests can be predicted from the number of stores, the type of stores, the number of households and floor plans, and the number of guest rooms and floor plans. For example, it can be estimated that the number of visitors to a store that requires a reservation is relatively smaller than that of a mass retailer. In terms of the number of households, it can be expected that there will be many singles on the floor where there are many one-room types, and if there are many floor plans with two or three rooms, the number of family users will increase. At accommodation facilities such as hotels, the number of users can be estimated based on the size of the guest rooms and the number of beds.

Column d is the expected number of elevators to be used. For example, if the building is a restaurant or mass retailer, the user often visits any floor only once, and it is rare to visit several times, for example. It is possible to expect the number of users to be about twice the number of people (use to visit the floor and use to move from that floor). Also, if it is a residential condominium, it will be the number of times the family goes out. It is possible to go out multiple times, such as going to work, shopping, and dumping garbage, and if it is an accommodation facility, going out for sightseeing, moving to a restaurant, moving to a hotel facility such as a gym or swimming pool, and multiple times per person In these cases, the number of users can be expected to be several times the number of users. In FIG. 3, the floor with a high expected number of users in the high-rise zone 98 is on the 17th floor.

The usage number ranking in column e is a ranking of the number of usages in the service floors of the high-rise zone 98 in descending order of the number of usages.

Column f shows the passing frequency. The passing frequency is the frequency of passing through the service floor without passengers getting on and off. In this embodiment, the frequency at which the elevator passes from the number of uses on each floor can be expected to be, for example, the sum of the number of uses on the floors above the corresponding stop floor as the pass frequency. This assumes a reciprocating operation between any floor in the low-rise zone 90 and any floor in the high-rise zone 98 in an elevator having a low-rise zone 90, a passage zone 94, and a high-rise zone 98.

The installation priority of row p is the order of the floors on which the power transmission unit should be installed, and is ranked in descending order of frequency of passage.

Next, the power supply control when the power transmission unit is installed on the floor where the car passes frequently will be described.

For example, when the power transmission unit 10 is provided on the 15th floor, which is predicted to pass through the car 40 most frequently, and the car 40 is on standby at the 17th floor, the power transmission unit 10 is not provided on the 17th floor. Therefore, the control unit moves the car 40 to the 15th floor, and the power transmission unit 10 starts power supply.

Here, since the passage frequency is higher in the lower layer than the 17th floor, there is a high possibility that the car 40 will move toward the lower layer in the future. However, if the power transmission unit 10 is provided on the 18th floor and the car 40 is moved to the 18th floor for charging, there is a high possibility that the movement will be in the opposite direction to the next call, and the next car call will be made. On the other hand, there is a risk of unnecessary movement.

On the other hand, as in this embodiment, by providing the power transmission unit 10 on the 15th floor, which has a high passing frequency, the next call is likely to go to the lower floors from the 17th floor, so the next call is also supported. Therefore, it is possible to reduce wasteful power consumption while the elevator moves up and down in a direction other than the desired ascending / descending direction for power supply, and power can be supplied.

In addition, since the 17th floor is the floor with the highest stop frequency in this embodiment, the frequency of the car heading to the lower floors is higher than the frequency of the car heading to the floors above the 17th floor. It is possible that it is expensive. Therefore, it is considered that the lower floors have a higher frequency of passage than the floors with the highest frequency of stoppages.

That is, by providing the power transmission unit 10 on the 15th floor where the frequency of passage of the elevator is predicted to be the highest, the power supply opportunity is improved. Further, in view of the frequency of use and the prediction of the frequency of passage, by installing the power transmission unit 10 on the floor where the frequency of passage is high in the high-rise zone 98, the opportunity for power supply is increased, and the configuration can be configured without impairing the convenience.

FIG. 4 is a shuttle elevator having a transit floor where the two elevators A and B are the low-rise elevator A from B1F to 13F and the high-rise elevator B from B1F to 19F, respectively.

The low-rise elevator A will have power transmission units 1001A and 1013A installed on the 1st floor of the lobby floor and the 13th floor of the top floor, respectively. If the floor with the highest expected number of uses is expected to be the 11th floor of the high-rise zone, the power transmission unit 1010A will be installed on the 10th floor below the 11th floor.

The middle-rise elevator B will have power transmission units 1001B and 1019B installed on the 1st floor of the lobby floor and the 19th floor of the top floor, respectively. If the floor with the highest expected number of uses is expected to be 17F among the high-rise zones excluding the top floor, the power transmission unit 1015B will be installed on 15F below 17F.

With the above configuration, by providing at least one power transmission unit on the floor above the passage zone where the frequency of passage is high, power can be supplied relatively quickly when the battery level is low. Opportunities for outages are reduced and convenience is improved.

FIG. 5 is an example of a method of determining the power supply floor to which the power transmission unit is installed when there are a plurality of elevators.

The three elevators D, E, and G are shuttle elevators with transit floors from B1F to 19F.

Elevators D, E, and G will install power transmission units 1001D, 1001E, and 1001G on the 1st floor of the lobby floor, respectively. In addition, power transmission units 1019D, 1019E, and 1019G will be installed on the top floor. This is an example of the case where the elevators D, E, and G are located near the building, and the floor that is expected to be used most is the 17th floor among the high-rise zones excluding the top floor.

FIG. 6 is a table showing the passing frequency order of the setting of the power supply floor. When setting the power supply floors for elevators D, E, and G, set the power supply floors on different floors in the order of passing frequency of the table.

In the elevator D, the power transmission unit 1015D will be installed on the 15th floor, which is lower than the 17th floor, which is the most frequently used elevator except the top floor, and has a high passing frequency.

In the elevator E, the power transmission units 1016E and 1017E will be installed on the 16th floor, which has a high passing frequency other than the 15th floor, which was decided to be installed in the elevator D, and the 17th floor, which has the highest number of uses. By installing the power transmission unit in this way, if the car is waiting on the 17th floor, you may charge it on the 17th floor, or move the car to the 16th floor in preparation for a call from the next lower floor, and then move the car to the 16th floor. It is also possible to charge the vehicle at the vehicle, which gives a wider range of operation control and enables the most efficient vehicle allocation control.

In the elevator G, the power transmission unit 1017E, which can transmit power even when the elevator is moving, will be installed in the range including the floors below the 17th floor, which is the most frequently used, from the 15th floor to the 17th floor, which have a high passing frequency.

With the above configuration, if the power transmission unit is preferentially installed on the floor that passes frequently and the installation conditions of the power transmission unit are changed for each elevator, charging will be performed relatively quickly when the battery level is low. be able to. By selecting the most suitable elevator to operate on the destination floor, the chances of service outages for other elevators will be reduced and convenience will be improved. In addition, by applying the power transmission unit 1017E, which can transmit power even while moving, it is possible to further improve the power supply opportunity and suppress the decrease in transportation efficiency due to insufficient power supply.

In addition, the table may be updated due to changes in visitors due to store renewal, etc., the floor with the highest number of uses may be determined, and the installation floor may be changed or set. FIG. 7 is after updating the table shown in FIG. The floor with the most usage has been changed from 17th floor to 15th floor. At this time, the floor where the power transmission unit 1016E of the elevator E (FIG. 5) is installed is changed to 15F. With the above configuration, when the tenant or usage pattern of the building is changed, it is possible to maintain convenience without reducing the frequency of power supply to the elevator by changing the power supply floor.

The number of users expected or the number of users does not include the number of times the elevator stops due to power supply. In addition, the number of uses is not limited to this. For example, the number of times the elevator is called may be used regardless of whether or not a person is used, or the stop time on that floor may be used. Further, the passing frequency is not limited to the frequency at which the elevator goes up and down the floor, but may be the time required for passing.

Further, each of the above configurations, functions, processing units, processing means and the like may be realized by hardware by designing a part or all of them by, for example, an integrated circuit.

In addition, the product does not always indicate a control line or an information line. In practice, it can be considered that almost all configurations are interconnected.
