no. 1 approach

[0026] figure 1 It is a figure which shows the whole structure of the group management control apparatus of the elevator concerning 1st Embodiment of this invention. exist figure 1 In the example of , the structure of an elevator system in which two multi-cabin elevators (hereinafter referred to as a machine A and a machine B) are installed side by side in a twenty-story building is shown. In the multi-car type elevators of the machines A and B, two cars are independently installed in the same elevator shaft (hoistway), respectively.

[0027] like figure 1 As shown, the elevator system includes a group management control device 11 , car control devices 12 a and 12 b , cars 13 a to 13 d , and a ride call recording device 14 . exist figure 1 In the example of , the group management structure shows only two units, the A-number and the B-unit, but it is not limited to this.

[0028] The group supervisory control device 11 collectively controls the operation of the plurality o...

[0077] Next, a second embodiment of the present invention will be described.

[0078] Since the device structure is basically the same as figure 1 are the same, so only the difference in processing will be described here.

[0079] In the second embodiment, when there are a plurality of ride calls that have already been registered, after the temporary allocation change is made to the respective change patterns, the car having the best proximity among the cars satisfying the reference value is adopted. degree change mode.

[0080] use Figure 7 It demonstrates concretely.

[0081] Now, it is assumed that the proximity determination unit 25 calculates the proximity of the car A as E1(A)=150 and the proximity of the motor B as E1(B)=70. When the reference value of the proximity is set to, for example, "100", E1(A)>100, and the proximity of the machine A exceeds the reference value. This means that there is a very high possibility that the upper car 13a and the lower car 13b o...

[0106] Next, a third embodiment of the present invention will be described.

[0107] Since the device structure is basically the same as figure 1 are the same, so only the difference in processing will be described here.

[0108] In the above-described first embodiment, regardless of whether they are in the same elevator shaft or not, when the proximity is equal to or greater than the reference value, the allocation change is actually performed to the ride call that has already been registered. However, in the third embodiment, priority assignment is changed to ride calls in the same elevator shaft.

[0109] use Figure 7 It demonstrates concretely.

[0110] Now, it is assumed that the proximity determination unit 25 calculates the proximity of the car A as E1(A)=150 and the proximity of the motor B as E1(B)=70. When the reference value of the proximity is set to, for example, "100", E1(A)>100, and the proximity of the machine A exceeds the reference value. This means tha...

Abstract

The present invention relates to a group management control device (11) of the elevator. The relative distance calculating part (24) of the group management control device (11) calculates the relative distance between the cages in one elevator well. The adjacent judging part (25) judges the proximity between the cages according to the relative distance. The temporary distributing alternating part(26) virtually distributes and alters the landing calls which are stored in the distributing recording part (23) and has finished recording to other cages. The distributing altering control part (27)takes the distributing altering for effective when the proximity after the distributing alternating of the temporary distributing altering part (26) is less than the reference value thereby outputting the distributing altering instruction to the distributing control part (22).

Description

technical field [0001] The present invention relates to a group management control device for an elevator having a plurality of independent cars in the same elevator shaft. Background technique [0002] In tall buildings with high elevator utilization, such as high-rise buildings, elevators in which a plurality of independent cars serve in one elevator shaft (lift path) are used. Such an elevator is called a "multi-car elevator". [0003] Compared with the double-deck elevator, in this multi-car type elevator, each car can be operated independently, and the improvement of the conveyance efficiency can be expected. However, this multi-car type elevator is different from the double-deck elevator in which two cars are always connected, and if the operation method is wrong, there is a possibility of collision between the cars in the same hoistway. For this reason, a special control for reliably preventing the collision between the cars and improving the conveying efficiency is...
