Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] In the present invention, when managing elevators in groups, a plurality of cars are made to stand by on a specific floor, a predetermined number of the cars are put on standby for door opening, and the rest are put on standby for door closing. The present invention relates to an improvement in an elevator operating device which is adapted to be operated.

[Conventional technology]

2. Description of the Related Art Conventionally, elevators that are group-managed return a plurality of cars to a departure floor, open doors, and wait on standby in order to increase transportation capacity at work. However, if a plurality of door openers are on standby, the waiting passengers will be dispersed and board, resulting in poor transport efficiency. In addition, if the starter is selected from the door opener and departs only in the order of the starter, if the user gets into a non-starter car, he or she waits for a long time. Therefore, according to Japanese Patent Publication No. Sho 62-15466, only the required number of doors are opened, and the rest are kept closed.

[Problems to be solved by the invention]

However, in the above-mentioned publication technology, when a door-opening car departs and the next door-opening car is selected from among the waiting-for-door-closing cars, the selected car may be far away from the waiting person. Have to travel a long distance. Therefore, it takes time to get on and it takes considerable time for the waiting passenger to reach the destination floor.

The present invention is to improve the above-mentioned problem, there are a plurality of door-closed waiting cars, and when selecting a door-opening car from among these, the number of waiting people near the landing of the door-closed waiting car is selected as the largest car. Provided is an elevator operating device.

[Means for solving the problem]

An elevator operating apparatus according to the present invention is an elevator operating apparatus in which a plurality of cars are on standby on a specific floor, a predetermined number of the cars are on standby for door opening, and the remaining plurality of cars are on standby for door closing. A plurality of waiting number detecting devices for respectively detecting the number of waiting people near the landing of each car on the floor, a comparing means for comparing the number of waiting people of each car based on the output of the waiting number detecting device, A control means is provided, wherein the waiting means selects a largest door-closing standby car as the next door-opening waiting car among the door-closing standby cars based on the comparison result by the comparing means.

[Action]

In the present invention, there are a plurality of standby cars for closing doors, and when selecting an open door car from among them, the control means based on the output of the number-of-waiting-standby detection device controls the number of waiting persons near the landing of the waiting-for-door-closing car. Choose the largest basket.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 illustrates the standby state of each elevator group managed and the detection range of the number-of-waiters detecting device. In the figure, (1a) to (1c) denote a to c at the departure floor (for example, the first floor). The elevators of Units a and c (1a),
(1c) is waiting for doors to close, and Unit b (1b) is waiting for doors to open. Ten people are in the car, closing the doors and trying to leave. A, B, and C are the number-of-waiters detecting devices (2
a) to (2c) detection ranges (hatched areas)
, Three people in B, and two people in C are detected.

FIG. 2 shows a main structure of a control means for selecting a car having a maximum waiting number of passengers in the vicinity of a landing of a door closing standby car, wherein (2a) to (2c) are known by ultrasonic waves or the like. A waiting number detection device that detects waiting customers at the landing and issues an output corresponding to the number, (3) a work time zone, for example, 8:00 to 9:00
(4) selects the operation at work based on the output of each of the number-of-customer detection devices (2a) to (2c) and the timer (3), and issues a door closing standby command to the departure floor. Means (5) for comparing the number of waiting persons based on the outputs of the waiting number detecting devices (2a) to (2c) of the units a to c; A door opening standby car selecting means for selecting a car with the largest number of waiting guests based on the comparison result and completion of the door closing standby instruction and issuing a door opening standby instruction is shown.

3 shows a hardware configuration diagram of the control means shown in FIG. 2, wherein (11) is a microcomputer, (11A) is a CPU, (11B) is a memory, (11C) is an input circuit, and (11C) is an input circuit. 11D) is an output circuit, and FIG.
3 is a flowchart showing a program stored in 1B) and operated by the CPU (11A).

Next, the operation of the above configuration will be described with reference to the flowchart of FIG.

Now, the time is 8:00, and the landing has a predetermined value or more (for example, 10
If there is a waiting person), YES is determined in step S41, the operation is started at work in step S42, and the departure floor closing standby command is issued to the units a to c. At this time, if it is determined that the car No. b has already been opened at the departure floor, the determination in step S43 is YES, and the state is continued. If the waiting passenger enters the car b and reaches a predetermined load (for example, 80%) or a predetermined time (for example, 20 seconds) has elapsed, the car b closes the door and starts. Then, step S43 becomes NO and the process proceeds to step S44. Since the units a and c are waiting for door closing, step S44 is YES and the process proceeds to step S45.

In step S45, the number of passengers in the vicinity of the landing of the door-close standby car is detected for each car, and in step S46, these are compared and the largest car is selected. In this case, since the number of the car a is nine, which is the largest, the car a is selected. Therefore, step S4
7 is YES, and in step S48, the first car is selected as the car with the door open waiting.

In this way, the waiting car for closing the door, which is waiting for a large number of people, is opened.

The explanation has been given at the time of commuting, but it may be at a different time, such as at lunch, and all three units are on standby at the departure floor, one of which is on standby with the door open. At
It is also possible to make two or more units wait for door opening.

〔The invention's effect〕

As described above, in the present invention, when the next door-opening standby car is selected from a plurality of door-closing standby cars, the number of passengers in the vicinity of the landing is set to the largest door-closing standby car. When boarding the door-opening car, there is an advantage that the traveling distance of the waiting person can be minimized, the boarding time is shortened, and the arrival time of the waiting person to the destination floor is shortened.
