Abstract

PURPOSE:To simplify the replacement work and control of parts by outputting an allocation command to an elevator with least number of starts among elevators with an evaluated value of which difference with the most excellent evaluated value is within a specified value. CONSTITUTION:When a landing call registration signal 1a from a landing call button 1 at a floor is input into a group control part 2, the group control part 2 inputs the information on elevators from control parts 3, makes allocation evaluation calculation for each elevator, and calculates an evaluated values. Also an allocation command 2a of the smaller evaluated value, i.e., the value for the least number of starts is output to elevator control parts 3, and the control parts 3 which received the allocation command 2a operates elevators controllably so that they respond to the landing call at that floor. Thus the parts replacement time is specified at the same time to simplify the replacement and control of parts.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control device.

[0002]

2. Description of the Related Art In general, when a plurality of elevators, usually three or more elevators, respond to a common hall call, a hall call registration signal generated from a hall button of a hall is once sent to the group management control device. Sent to. The group management control device evaluates the state of each unit (travel position, elevator traveling direction, time required to respond to the hall call, elevator load, etc.) to obtain an evaluation value, and based on this evaluation value Group management control is performed by assigning elevators that can respond optimally to the hall calls.

[0003]

However, in the conventional elevator group management control device, the evaluation calculation of each elevator is performed for the hall call, and the allocation command is issued based on the evaluation value. The number of times of starting each elevator based on the allocation command is not constant, and some deviation occurs. For example, when the evaluation values of a plurality of elevators are the same, biased allocation is always performed. When variations (bias) occur in the number of times each elevator is started (the number of times starting and stopping is one cycle), some elevator components may be replaced depending on the number of times they are started. Therefore, there is a problem in that the parts replacement timing is delayed, the replacement work must be performed each time, and the parts management of each elevator becomes complicated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to equalize the number of times each elevator under group management control is started, to arrange the parts replacement timing, and to simplify the parts replacement work and the parts management. It is to provide an elevator group management control device that can perform.

[0005]

In order to achieve the above-mentioned object, the present invention operates a plurality of elevators on a plurality of floors and responds to a hall call from a hall call button provided at the hall. In an elevator group management control device that allocates an optimum elevator, a means for calculating an evaluation value by performing an evaluation calculation for allocation for each of the plurality of elevators with respect to a generated hall call, and a means for calculating the evaluation value When there is an elevator that outputs an allocation command to a good elevator and an evaluation value whose difference from the best evaluation value is within a predetermined value, the difference between the elevator having the best evaluation value and the best evaluation value is Among elevators with an evaluation value within a predetermined value, the elevator with the least number of starts or an elevator determined by random number calculation To the group management control device of the elevator, characterized in that a means for outputting an assignment command to the chromatography.

Furthermore, in a group management control device for elevators, a plurality of elevators are activated for a plurality of floors, and an optimum elevator is assigned to a hall call from a hall call button provided in a hall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a system configuration of an elevator group management control device of the present invention. The elevator group management control device includes a hall call button 1 provided at a hall of an elevator on each floor, and a hall call button 1 Hall call registration signal 1
The group management control unit 2 that inputs a and assigns the hall call to the optimum elevator, and the individual information of each elevator (position, speed, traveling direction, in-car load, call registration information, number of starts, etc.) It is provided with a machine control device 3 that manages and controls operation.

When the hall call registration signal 1a from the hall call button 1 on a certain floor is input to the group management control unit 2, the group management control unit 2 inputs individual information of each elevator from each unit control unit 3. Then, the evaluation value is calculated by performing the allocation evaluation calculation for each elevator. The evaluation calculation result takes a value from 1 to 1000, and the smaller evaluation value is the better allocation evaluation. Therefore, the group management control unit 2 outputs the allocation command 2a to the optimum elevator machine control unit 3 based on this evaluation value, and the machine control unit 3 which has received the allocation command 2a calls the elevator to the hall for the floor. The operation is controlled to respond to.

The operation of the allocation control of the group management control unit 2 in this embodiment will be described with reference to the flowchart of FIG. First, it is judged whether the average unanswered time (average time from the occurrence of a hall call to its deletion) at the floor where the hall call is generated is a predetermined value (eg, 30 seconds) or less (step 101), and 30 seconds Step 102 if
Go to step 104 if greater than 30 seconds.

In step 102, it is judged whether or not there is a machine whose difference from the allocation evaluation calculation result (evaluation value) of the machine (elevator) having the best evaluation is within a predetermined value (for example, 50). If there is a machine whose evaluation value difference is within 50, step 10
Go to step 3, and if the difference between the evaluation values is 50 or more, go to step 10.
4 Continue.

In step 103, among the machines having the difference in evaluation value of 50 or less, the machine having the smallest number of startups is determined as the allocated machine and the allocation command 2a is output. In step 104, the average unanswered time is longer than 30 seconds, or there is no other machine whose difference from the allocation evaluation calculation result (evaluation value) of the machine with the best evaluation is within 50. In these cases, As usual, the machine with the best evaluation calculation result is determined as the allocated machine and the allocation command 2a is output.

As described above, according to this embodiment, when the average unanswered time on the floor call generation floor is long (when the average unanswered time is 30 seconds or more), that is, when there is a large demand of passengers on the generation floor. There is a possibility that another elevator will arrive at the floor by car call before the elevator to which the hall call is assigned responds to that floor. Allocation control, that is, control is performed to allocate to the elevator with the best (smallest) evaluation value, and if the average unanswered time is short, the elevator closest to the best evaluation value is checked and allocation control based on the number of starts As a result, the assigned elevators can be dispersed and the number of times each elevator is activated can be leveled.

FIG. 3 is a flow chart showing the second embodiment of the present invention. FIG. 3 is a flowchart showing a processing function according to the present embodiment incorporated in the group management control unit 2 in FIG. 1, and a normal allocation for determining an elevator to be allocated when a hall call provided at the hall is generated. It shall be executed after performing the evaluation calculation.

Here, the allocation evaluation calculation is performed for each elevator, and the evaluation calculation value takes a value from 1 to 1000, which means that the allocation evaluation with a small value is good. First, it is judged whether the average unanswered time at the floor call generation floor is a predetermined value (for example, 30 seconds) or less (step 20
1) If it is less than 30 seconds, proceed to step 202. If it is longer than 30 seconds, proceed to step 204.

In step 202, it is determined whether or not there is a machine whose difference from the allocation evaluation calculation result (evaluation value) of the machine (elevator) having the best evaluation is within a predetermined value (for example, 50). If there is a machine whose evaluation value difference is within 50, step 20
Go to 3 and if the difference between the evaluation values is 50 or more, step 20
4 Continue.

In step 203, random numbers are generated and operated in order to determine the allocation of these machines among the machines whose difference in evaluation value is within 50. When the number of machines within the value is No.1, No.2, No.3, when these three data are input, a random number is generated from these data and a desired value is obtained to output one data.) The output The data is assigned to the assigned machine and output is performed.

At step 204, if the average unanswered time is longer than 30 seconds or there is no other machine whose difference from the allocation evaluation calculation result (evaluation value) of the best evaluated machine is within 50, In the case of No. 2, the number of the best evaluation calculation result as usual (the number of the evaluation value is small) is determined as the assigned number and the assignment command 2a is output.

As described above, in this embodiment, the elevators having the evaluation values close to the best evaluation value are checked, and the allocation is determined by the data obtained by the random number from the elevators having the best evaluation. Therefore, the assigned elevators can be scattered. It should be noted that when the number of activations is the same in step 103 of the first embodiment, allocation may be performed by random number generation in the second embodiment described above.

[0019]

As described above, according to the present invention, since it is possible to standardize the number of times of starting each elevator under group management control, the parts replacement timing can be aligned, and the parts replacement work and the parts management can be simplified. Can be realized.
