Description

  The present invention relates to an elevator system provided with a plurality of elevators.

  In general, when a plurality of elevators are provided side by side to provide services to passengers, it is general that each elevator has the same rated speed. Further, in recent years, with the building of a high-rise building, the elevator car has been moved up and down at a higher speed. However, in a large-scale building, a plurality of elevators are installed side by side or connected so that it is difficult to increase the speed of all elevators from the viewpoint of cost and energy saving. Therefore, for example, in a high-rise building where there is a VIP-dedicated floor or a hotel above and serves a hotel user, a plurality of elevators with different rated speeds are installed side by side.

Moreover, in order to reduce the electric power consumption accompanying a driving | running | working of an elevator, it is known to reduce the speed of a cage | basket | car from usual, such as when traffic becomes quiet, for example, it describes in patent document 1. FIG.
In addition, it is known that the speed from the evacuation source floor to the evacuation destination floor is shortened by increasing the speed during emergency operation in order to satisfy the ride comfort during normal operation and to safely increase the lifting speed during emergency operation. For example, it is described in Patent Document 2.

In a large-scale system, it is preferable to speed up only a specific number of cars instead of speeding up all elevator cars from the viewpoint of energy saving. However, in such a configuration, users tend to be biased toward the elevator with the higher rated speed, which greatly impairs the overall transport efficiency.
In the above-mentioned patent document, since only the traveling speed of one elevator is changed, a large-scale system in which a plurality of elevators are installed or connected to each other is not taken into consideration. If only applied, in front of a specific elevator in the hall, the user gets into the elevator smoothly, hinders the flow and hinders the flow and becomes a major obstacle to transportation efficiency.

  The object of the present invention is to solve the above-mentioned problems of the prior art, eliminate the bias of the user even in a large-scale system in which a plurality of elevators are arranged, and reach the target floor as soon as the user demands. In response to this, it is to prevent a decrease in serviceability and transportation efficiency.

  In order to achieve the above object, the present invention provides an elevator system in which a plurality of elevators are provided, and a user gets on a car of any one of the elevators. At least one of the plurality of elevators is another A high-speed elevator with a rated speed higher than that of the elevator, and the high-speed elevator is operated at a speed slower than the rated speed as a normal driving condition in a normal state, and in a predetermined special driving condition set in advance. The vehicle is operated at a higher speed than the rated speed of the other elevator.

  According to the present invention, at least one vehicle is a high-speed elevator that has a higher rated speed than other elevators, and normally operates at a speed slower than the rated speed. It is possible to suppress getting in the elevator of the elevator. Therefore, even in a system in which a plurality of elevators are arranged, it is possible to eliminate user bias and prevent deterioration in serviceability and transportation efficiency.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing an elevator system. In a high-rise building, there are general apartments below the hotel lobby floor on the 120th floor, and the hotel is configured above the hotel lobby floor. ing. The hotel user gets on one of the shuttle elevators composed of four elevator units 1 to 4 and goes to the hotel lobby floor. The elevators 1 and 3 are high-speed elevators with a rated speed of 18 m / s, and are stopped on a special floor such as the VIP floor on the 110th floor. On the other hand, the other elevator machines 2 and 4 have a rated speed and a rated speed of 10 m / s slower than the rated speeds of the elevator machines 1 and 3, and do not stop on the special floor. As elevators for hotels that provide services from the hotel lobby floor to the hotel floors, elevators 5 to 8 are arranged.

  FIG. 2 is a block diagram showing a schematic configuration of elevators 1 and 2 having different rated speeds.

  The group management control device 9 that performs group management control of each elevator 1 to 4 includes an information control input / output device 10, a control device 11 of the elevator 1, a control device 12 of the elevator 2, and a service floor The hall call buttons 13 and 14 are connected.

  The control device 11 of the high-speed elevator No. 1 having a fast rated speed includes a hall information guidance device 15 installed at the landing on each stop floor, a current floor display installed in the car 16, a lift direction display, and voice guidance. In-car information guidance device 17, in-car registration button 18 for displaying registration of destination floor and car call floor, door open button 19, door close button 20, and hotel users possess and are portable. A card reader 21 or the like that reads information from a card or a portable terminal such as a mobile phone or a smartphone is connected.

  The control device 12 of the elevator 2 with the lower rated speed includes a hall information guidance device 22 installed at the landing on each stop floor, a current floor display installed in the car 23, a lift direction display, voice guidance, etc. The car information guide device 24 including the car, the car registration button 25 for displaying the registration of the destination floor and the car call floor, the door opening button 26, the door closing button 27, and other normal components are similarly provided. Does not have a card reader.

  FIG. 3 is a block diagram showing the control device 11 of the high-speed elevator 1 having a high rated speed. The control unit 40 takes in signals from the in-car registration button 18, the door opening button 19, the door closing button 20, and the like, and the car. Drive control means 28 for controlling the elevation of 16 and determination means 29 for determining the traveling speed by determining the normal traveling condition and the special traveling condition. The determination unit 29 determines whether normal driving conditions that are normal times or predetermined special driving conditions that are set in advance with respect to normal times. That is, the determination unit 29 refers to the data table 30 when taking any one of the control operation command signal from the group management control device 9, the recognition signal from the card reader 21, and the destination registration signal of the specific floor. Extract related data corresponding to special driving conditions. When none of the signals is captured, the determination unit 29 extracts the relevant data on the normal driving conditions.

  When the normal traveling condition is determined, the determining unit 29 reads the normal traveling speed 32 (10 m / s) from the traveling speed setting unit 31 based on the corresponding related data, and commands the drive control unit 28. Therefore, although it is a high-speed elevator, the elevator car 16 is controlled to move up and down at a speed slower than the rated speed of 18 m / s. Also, the hall information guide device 15 and the in-car information are provided as normal information corresponding to the fact that the elevators are moved up and down at a speed slower than the rated speed of 18 m / s or that each elevator is operated at substantially the same speed. Or output to the guidance device 17.

  When it is determined that the travel condition is special, the determination unit 29 extracts the special travel speed 33 (18 m / s) from the travel speed setting unit 31 based on the corresponding other related data, and instructs the drive control unit 28 to instruct the car 16. The information output means 34 outputs corresponding special information to the hall information guide device 15 and the car information guide device 17. The normal travel speed 32 as a normal travel condition is a travel speed of 10 m / s, and the normal output information is a display output or a voice output indicating that the vehicle is operating at a travel speed of 10 m / s. On the other hand, the special traveling speed 33 as the special traveling condition is, for example, a rated speed of 18 m / s, and the special information is operated at a rated speed of 18 m / s, which is higher than the rated speed of other elevators. It is a display guidance by display output, voice output, etc., that it is operating at a higher speed than other elevators.

  The normal traveling speed 32 may be a speed slower than the rated speed of 18 m / s, even if it is not a traveling speed of 10 m / s substantially matched to the rated speed of the other elevators 2 and 4, and the special traveling speed 33 is Even if it is not necessarily the rated speed, it is sufficient if it is faster than the normal running speed, and if the user needs to reach the destination floor early, that is, if it is necessary to go to the destination floor early, the driving speed should be high. . Further, the traffic flow may be varied depending on a high traveling speed in order to increase the transportation capacity when it is congested, a slow traveling speed when it is quiet, a slow traveling speed when energy saving demand is large, and the like.

  Hereinafter, it is assumed that the elevators 1 and 3 are operated at 10 m / s in which the normal traveling speed 32 is substantially matched with the other elevators 2 and 4 and the special traveling speed 33 is operated at a rated speed of 18 m / s. It will be explained as a thing.

FIG. 4 is a flowchart showing a discrimination process between the normal running condition and the special running condition.
Whether the determination means 29 recognizes the user as a hotel user by reading from the card reader 21 in step S1, or the car call registration on the specific floor or the destination registration on the specific floor among the signals from the in-car registration button 18 in step S2. In step S3, it is determined whether or not a control operation command signal from the group management control device 9 has been received. If neither is detected, it is determined in step S4 that the driving condition is normal, and the traveling speed is set to 10 m / Set to s. When any one is detected, the determination means 29 determines with special driving conditions at step S5, and sets a driving speed to 18 m / s of a rated speed.

  Normally, the elevators 1 and 3 are not operated at a rated speed of 18 m / s but are operated at a traveling speed of 10 m / s slower than that. Accordingly, in the shuttle elevator that goes from the first floor lobby floor to the hotel lobby floor on the 120th floor, all the elevators 1 to 4 are operated at substantially the same traveling speed, that is, 10 m / s. 3 outputs information to be output to the hall information guide device 15 installed at the landing on each stop floor and the in-car information guide device 17 installed in the car 16 in the data table 30. The information obtained by referring to the fact that the vehicle is currently driven at a traveling speed of 10 m / s is output by display guidance or voice guidance.

  Therefore, users of shuttle elevators can use the elevators 1 and 3 with high rated speed by guidance without being concentrated in the elevators and distributed to each unit. There is no risk of greatly compromising the overall transportation efficiency without confusion.

When the passenger who got into the elevators 1 and 3 is a hotel user and the card reader 21 reads the card carried, the determination means 29 recognizes this and determines that it is a special driving condition, and the data table 30 is stored. The related data corresponding to the special driving conditions is extracted by referring to the data.
Next, the determination unit 29 extracts the special traveling speed 33 from the traveling speed setting unit 31 according to the extracted related data, and changes the traveling speed to 18 m / s, which is a high speed. In addition, the determination unit 29 selects output data that matches the special driving condition from the information output unit 34, and the hall information guide device 15 installed at the landing on each stop floor and the in-car information guide installed in the car 16. As the selected output data, the device 17 outputs and guides, for example, display or voice that the vehicle is currently operating at a rated speed of 18 m / s.

  Further, the determination means 29 also refers to the data table 30 to determine whether the car call registration on the specific floor or the destination registration on the specific floor among the signals from the in-car registration button 18 corresponds to the special driving condition. Extract data. In this case as well, the traveling speed is changed to 18 m / s and guidance is provided that the vehicle is currently operating at the rated speed of 18 m / s. Further, the same applies when a control operation command signal for performing a control operation with the highest priority given to evacuating the user is received from the group management control device 9 when an earthquake or a fire occurs.

  In addition, although the elevators 1 and 3 have been described as operating at a normal traveling speed of 10 m / s, which is the same as that of the other elevators 2 and 4, it is only necessary to reduce the speed from the rated speed of 18 m / s. It is also possible to balance user bias and serviceability as an intermediate value from s to 18 m / s.

  As described above, in normal driving conditions, the elevator is operated at a lower speed than the rated speed under special driving conditions. Therefore, simply because the rated speed is high, the user is prevented from getting into the elevator. Thus, it is possible to prevent uneven use in each elevator. Moreover, in order to operate the elevator at a speed that is faster than the speed at the time of normal driving under special driving conditions, the function of high rated speed is utilized without reducing service for special floor users. Overall service can be improved.

Further, since the control operation command signal from the group management control device 9, the recognition signal from the card reader 21, and the destination registration signal on the specific floor are used as the special traveling conditions, a high rated speed is obtained under certain special traveling conditions. Can be used to provide high-quality services.
In addition, since the elevator with the higher rated speed is operated at almost the rated speed of the elevator under special driving conditions, the ability of the higher rated speed should be fully utilized to provide high-quality services. Can do.

In addition, the elevator with the higher rated speed is operated at a running speed that almost matches the rated speed of other elevators with a slower rated speed under normal driving conditions. It is possible to effectively suppress the bias that a person concentrates on the elevator.
In addition, during normal driving conditions, the passengers who are waiting at the landing and before entering the car are notified that the elevator with the higher rated speed is servicing at a lower speed. The user who is standing by can be guided to other elevators, and the concentration of users to specific elevators can be effectively suppressed.
