Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator operating system, and particularly to an elevator hall call canceling device suitable for improving operating efficiency.

[Background of the invention]

Conventional elevators memorize all 1 platform calls and car calls, service calls in the same direction as the operating direction in sequence, and when there are no more calls in the direction of travel, they automatically reverse direction and perform the same service. This is a collective control operation system, and it takes five steps to complete the service when a call as shown in FIG. 3 is registered. In the same figure, even if a passenger C accidentally gets into an elevator that is operating in the opposite direction to the destination floor of C, the above operation method will be able to move the elevator to the 4th floor where there are no passengers (actually, after reversing the direction of operation). The train had the disadvantage that it had to stop in order to respond to a call at the first platform (when passengers had already boarded the train).

[Purpose of the invention]

The present invention is intended to improve the above-mentioned problem, and detects that a car call in the direction opposite to the operating direction is registered while the elevator is stopped, and determines that a landing call for a floor where the elevator is stopped is a useless call. By canceling the elevator
An object of the present invention is to provide a platform call cancellation device that improves the operating efficiency of a vehicle.

[Summary of the invention]

In order to achieve the above object, the present invention, as a means for detecting wasted calls, takes the logical product of a driving direction signal, a car position signal, and a rear call signal in the opposite direction to obtain a wasted hall call signal. This is intended to improve operating efficiency by canceling platform calls in the opposite direction to the operating direction of the elevator-stop floor.

Hereinafter, one embodiment of the present invention will be described in detail using FIGS. 1 and 2.

Corresponding to the first floor, the relay on the car call registration floor is activated.

Corresponds to the second floor. Z4U1. Z4D1. Z3U1゜Z3

D2U is an upward landing call detection relay, and corresponds to the 4th floor, 3rd floor, and 2nd floor, respectively. D4D.

D3D and D2D are downward landing hall call detection relays, and correspond to the 4th floor, 3rd floor, and 2nd floor, respectively.

FIG. 1 is an explanatory diagram of the operating state showing the movement of the elevator. In the figure, A and B are passengers in the car, and their destination floors are the 4th and 5th floors, respectively. C is a passenger on the 4th floor platform, and his destination floor is the 1st floor.

In the figure, the vertical axis represents the elevator stop floor, and the horizontal axis represents the time flow until the service is completed.

Next, the operation of this embodiment will be explained. In FIG. 1, the elevator starts from the 1st floor and stops at the 4th floor, which is the destination floor of customer A, to take the passenger down. At this time, customer C
When a passenger mistakenly gets into the car and registers a car call for the first floor, which is the destination floor of passenger C, the position detection relay corner contact A4 is closed because the elevator stops on the fourth floor as shown in Figure 2. . Since the elevator is in service in the upward direction, the normally open contact BU of the upward direction detection relay is closed. When the first floor car call is registered by the passenger C, the normally open contact C1 of the first floor car call detection relay is closed. In other words, when a car call in the direction opposite to the driving direction is registered, (+)-A4-BU-C1-Z4D-(
-) The useless call detection relay 24D in the direction 4th floor below the LZ is
energized. By energizing the 4th floor downward wasteful call detection relay 24D, the normally closed contact Z of the 4th floor downward wasteful call detection relay
4D1 is open and the downward landing call detection relay D4D
is released. In other words, the boarding area for the fourth floor down was canceled. In FIG. 1, the elevator then operates to the 5th floor, which is the destination floor of the customer B, takes the customer B down, reverses direction, and operates to the 1st floor, which is the destination floor of the customer C, and the service is completed. As described above, by canceling the unnecessary calls to the 4th floor platform, the conventional method required 5 steps to complete the service, but now it takes 4 steps, leading to improved operational efficiency.

〔Effect of the invention〕

As explained above, according to the present invention, when a passenger mistakenly gets into an elevator that is operating in the opposite direction, unnecessary boarding calls are canceled, thereby improving operational efficiency.
Nade has a great effect in saving energy and reducing customer waiting time.
