Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for registering elevator hall calls.

When you operate a hall button installed at an elevator hall, the hall call for that floor is registered. In an elevator called an allocation system, a group management operation is performed in which the car most suitable for responding to a registered hall call is selected, this car is assigned to the hall call, and the car is serviced on that floor.

On the other hand, on specific floors where executive offices and the like are located, there is a demand for important customers who leave the executive offices or reception rooms, which are far away from the elevator landings, to be able to board the elevators quickly. However, in the elevator operating system as described above, the user must walk to the hall, operate the hall button there, and wait for the car to arrive. In other words, even though the important customer has the intention of using the elevator at the time of leaving the above room, he is unable to call for a car while walking to the landing.
It's inconvenient.

Further, when a car responds to a hall call, a deceleration and stop command is issued to a car that can decelerate and stop on that floor. In other words, even if a hall call is registered when the car is moving up or down within the distance where it can decelerate and stop, the car will not be able to respond. , I ended up passing that hall call. Therefore, near intermediate floors where the car often moves up and down at its maximum speed, the distance over which it can decelerate and stop becomes longer, and accordingly, when a car is registered with a hall call, the percentage of cars passing through that hall call increases. , the waiting time will be longer. This phenomenon is increasing as elevator speeds increase as buildings become taller.

This invention solves the above-mentioned drawbacks, and aims to provide an elevator hall call registration device that allows customers to quickly register calls without wasting time until they reach the elevator hall. do.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In Figure 1, 1 to 3 are elevator cars, 4 is an elevator landing, 5 is a hall call button installed on the wall of the hall 4, 6 is a reception room located far from the hall 4, and 7 is a hall remote call button installed on the wall of the reception room 6.

In Figures 2 and 3, (+) and (-) are DC power supplies, 8 is the hall remote call registration relay, 8a, 8b
is its normally open contact, and 11 to 13 are cages 1 to 1, respectively.
Car arrival time prediction that predicts and calculates the arrival time to the floor where the hall remote call button 7 is located (hereinafter referred to as this floor) from the car call, the hall call, the car speed at that time, the car position, etc. The device emits a signal for the predicted times T ₁ to T ₃ and is known in the art. 21 to 23 are prediction times T ₁ to _{T 3} respectively
Compare the walking time Ta from the position of the landing remote call button 7 to the landing 4, and calculate the predicted time T ₁ to _{T 3}
A comparison arithmetic device that emits a signal only when is longer than
That is, for cars that can arrive earlier than the required walking time Ta, the signal is cut here. 31 to 33 are comparison calculation devices 21 to 33, respectively.
This is a comparison calculation output generation device that compares predicted times T ₁ to _{T 3} that have passed through 23 and generates an output only when its own predicted times T ₁ to _{T 3} are the shortest. Therefore, among the comparison calculation output generation devices 31 to 33, only one can generate an output. 41 to 43 are amplifiers, 5
1 to 53 are output relays energized by the outputs of amplifiers 41 to 43, 51a to 53a are their normally open contacts, 61 to 63 are assigned relays, and 61a to 63a are
are their normally open contacts, 61b to 63b are normally closed contacts, and 71 to 73 are the normally open contacts for cars 1 to 1 on this floor, respectively.
This is a car position contact that opens when car number 3 arrives.

Next, the operation of this embodiment will be explained.

Now, when the hall remote call button 7 is pressed in the reception room 6, the hall remote call registration relay 8 is energized and self-maintained by closing the normally open contact 8a. In addition, the normally open contact 8b is also closed, and the car arrival time prediction device 11
- 13, calculate the predicted arrival time of each car, transmit the predicted time signal to the comparison calculation devices 21 to 23, and calculate the predicted time shorter than the required walking time Ta.
The predicted time signals of T ₁ -T ₃ are cut off here, and the predicted time signals of longer ones are directly transmitted to the next comparison calculation output generation devices 31 to 33. Comparison calculation output generation devices 31 to 33 compare the predicted times T ₁ to T ₃ of other cars, generate an output only when the predicted time T ₁ to T ₃ of the own car is the shortest, and output it to the amplifier 41. -43, and energizes one of the output relays 51-53.

If car 1 is now assigned to arrive at this floor, output relay 51 is energized and contact 51a is closed. As a result, the allocation relay 6
1 is energized and self-retained by closing the contact 61a, which means that the assignment to car 1 is completed. At the same time, contact 61b is opened, so hall remote call registration relay 8 is deenergized and double assignment is prevented. When car 1 arrives at this floor, car position contact 71 opens, assignment relay 61 is deenergized, and normal operation returns. It is clear that the same applies when assigned to car 2 or car 3.

In addition, if the predicted arrival time T ₁ to _{T 3} of the assigned car is long, the predicted arrival time T ₁ to _{T 3} is the required walking time.
You can also assign it to a car below Ta and have that car wait on this floor.

Although the above embodiment described only a specific floor,
It is also possible to apply it to multiple floors.

As explained below, in this invention, a landing button is provided at a location away from the landing, and when this landing button is operated, a car that can arrive at the landing after the elapse of the time required to go from that location to the landing is provided. Since the seats are allocated, the waiting time at the landing can be minimized, and it is also possible to avoid causing inconvenience to passengers waiting on other floors.
