Problems solved by technology

[0010] Passengers waiting in front of an elevator that can switch operation modes will not only be confused when they hear the arrival announcement of other elevators, but also need to move to other elevators, so it is inconvenient for passengers to use
In addition, slow-moving passengers, such as the elderly or sick, may not be able to get on the elevator due to the need to move from the elevator they are waiting for to another elevator
On the other hand, since it is necessary to wait for slow-moving passengers, the door-opening waiting time of the elevator car becomes longer, and the operating efficiency of the elevator decreases.

[0031] Refer to the following Figure 1 to Figure 5 The first embodiment will be described. In this embodiment, general hall calls are mainly described, but this embodiment may also be applicable to other types of hall calls such as hall calls for wheelchairs.

[0032] In this embodiment, the case where the elevator performs special operation for specific passengers or specific purposes is taken as an example for illustration. dedicated mode. However, the present embodiment is not limited by the above example, and can be applied to all elevator systems having elevators that can be switched to an operation mode that does not respond to general hall calls.

[0033] figure 1 The overall configuration of the group-controlled elevator system 1 is shown. The group-management elevator system 1 includes, for example, a plurality of elevators 10 and a group-management control device 20 .

[0034] The elevator 10 has, for example, an elevator car 11, a hoist 12, a main rope 13, a c...

[0063] Refer to the following Image 6 A second embodiment will be described. In each of the following embodiments, the differences from the first embodiment will be mainly described. In this embodiment, the special evaluation value added to the specified elevator car that can be switched to the dedicated operation mode is set according to the traffic volume of the group management elevator system.

[0064] Image 6 It is a graph for calculating the special evaluation value. Image 6 The vertical axis of represents the special evaluation value, and the horizontal axis represents the traffic volume (transportation volume). The traffic volume can be calculated, for example, by dividing calls (both hall calls and car calls) occurring on a specific floor or floors by unit time.

[0065] The special evaluation value is set to decrease from the initial value Pa1 to the lower limit value Pa2 (Pa1>Pa2) as the traffic volume increases. And the larger the traffic volume, the smalle...

[0068] Refer to the following Figure 7 A third embodiment will be described. In this embodiment, the special evaluation value is adjusted according to the service time zone of the group management elevator system. Figure 7 It is a graph for calculating the special evaluation value. Figure 7 The y-coordinate of represents the special evaluation value, and the abscissa represents the time. In the on-duty time zone T0-T1 in the morning and the off-duty time zone T4 in the evening, the special evaluation value is set as the lower limit value Pa4. During the daytime T2-T3 when the traffic volume is small, the special evaluation value is set to the upper limit value Pa3.

[0069] Therefore, in the present embodiment, passengers can be transported using a predetermined elevator car that can be switched to a dedicated operation mode during morning and evening congestion periods. Thereby, congestion can be alleviated, and the operation efficiency of the group-management elevator...

Abstract

The invention provides a group management elevator system which sets possibility of allocating a hall call to a specified elevator lift car to be different from those to other elevator lift cars, so as to increase convenience for passengers. A group management control device excludes an elevator lift car which runs in a specified running mode from allocation objects of hall calls (S42). After a new hall call is logined (S43, YES), the group management control device calculates an evaluation value used for allocation according to a current position, load, the number of allocated hall calls, a heading layer and a moving direction of the elevator lift car. Besides, the group management control device calculates a specified evaluation vale for the specified elevator lift car capable of being switched into the specified running mode, and adds the specified evaluation vale and the evaluation value used for allocation. The group management control device allocates the hall call to the elevator lift car with the lowest evaluation value.

Description

technical field [0001] The invention relates to a group management elevator system. Background technique [0002] In a group management elevator system that manages the operation of multiple elevators, when a passenger presses a hall call registration button provided in the elevator hall, a hall call is generated, and at least one elevator car is assigned to the generated hall call (Patent Documents 1, 2). In addition, there is also known a technique that controls allocation of hall calls so that only specific passengers or specific purposes can use the elevator (Patent Documents 3 and 4). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 59-153774 [0006] Patent Document 2: Japanese Patent Application Laid-Open No. 4-197969 [0007] Patent Document 3: Japanese Patent Laid-Open No. 2003-040534 [0008] Patent Document 4: Japanese Patent Laid-Open No. 2010-260703 [0009] During the normal operation of an...
