Description

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

In recent years, in elevator group management systems that manage cars arranged side by side as a group, when a hall call is registered, the elevator that will serve the hall call is selected, and the elevator is assigned to the floor where the hall call is registered. A method of providing advance notice to that effect has been considered.

According to the above system, passengers waiting at the hall can wait without hesitation in front of the entrance of the elevator for which they have been notified (for example, the arrival forecast light has been turned on), and high-quality service can be expected for the passengers waiting at the hall.

On the other hand, if a car that has not been notified in advance arrives first due to a car call, etc., it will be difficult to board the car, and the reliability of this advance notification system itself will be reduced.

In order to solve this problem, it is considered that if a car that has not been notified in advance arrives first, the hall call will not be cancelled.

It is true that with this method, the car that has been announced will arrive anyway, so passengers can, for example,
People who don't want to move and are not in a hurry can wait for the car that has been notified to arrive, and people who are in a hurry can choose which car to ride, such as getting on the car that arrives first. I'm satisfied with the fact that it doesn't make the situation worse.

However, with this method, even if a car for which advance notice is given is significantly delayed, if a car for which advance notice has not been given arrives, the boarding call is not uniformly canceled, so passengers who wait for advance notice without boarding the car arrive. It is easy to complain about long waiting times.

This invention improves the above-mentioned drawbacks by determining whether to hold or release a hall call based on the expected arrival time of the car that was notified in advance when a car other than the car that was notified in advance arrives first, thereby improving driving efficiency. It is an object of the present invention to provide an elevator hall call registration device which improves the service quality and improves the service.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Figure 1, a-c are the cars of cars A-C, car a has arrived at the 7th floor in the ascending direction, car b is ascending the 5th floor, and car C is the 1st car.
Suppose you are climbing a floor.

3a. It is assumed that 7a is an ascending call registered at the 3rd floor landing and the 7th floor landing, respectively, and 3a is assigned to car No. C.

6b is a car call on the 6th floor registered in car b, and 4c and 5c are car calls on the 4th and 5th floors, respectively, registered in car e.

In Figure 2, IUB to 7UB are up button signals that become rHJ when the up call buttons on the 1st to 7th floors are pressed, and 2DB to 8DB are up button signals that become rHJ when the up call buttons on the 2nd to 8th floors are pressed, respectively. When "H" exit button signal, IU

2.7U3 is or gate, 7U4 is and gate, IU
X to 7UX are ascending call registration circuits for the 1st to 7th floors, respectively.
Similarly, DX to 8DX are down call registration circuits for the second to eighth floors.

The circuit shown is only for climbing up to the 7th floor, but similar circuits can be used for other floors and directions.

Also, signals with the suffix a''c indicate those related to machines A to C, respectively, and signals with a circle at the input of the AND gate, such as 7U4, indicate that the signal level is reversed.

The same applies to FIG. 3, which will be explained below.

Figure 3 shows a circuit for car a, and a similar circuit is required for car c as well.

In the figure, 1UA to 7UA are registered with ascending calls from the 1st to 7th floors, respectively, and ascending call assignment signals that become "H" when assigned to answer them, and 2DA to 8DA are descending calls from the 2nd to 8th floors. Call assignment signals, 1CC to 8CC are car call registration signals that become "H" when car calls on the 1st to 8th floors are registered, and 1F to 8F are car call registration signals that become "H" when the car calls are located on the 1st to 8th floors, respectively. 11 is a car position signal that becomes "H"; 11 is a rising operation signal that becomes rHJ when the car is in ascending service;
12 is also a descending operation signal, 13 is a constant value signal indicating a certain constant value (for example, 3), and 7U5 is an adder that adds two inputs and outputs the result, and the output of 7U9 is "H". When , 1 is input.

7U6 is a gate circuit, which outputs the input signal from the adder 7U5 when the input signal marked G is rLJ, and outputs the input signal G.
When the input is "H", the output is reset to zero.

7U7 is a comparator and outputs an rHJ signal when the input value on the side) is larger than the input value on the side ←).

7U8.7U9 are or gates, 7U10 to 7U12 are AND gates, IUY to 7UY are circuits for determining whether to go up to the 1st floor to the 7th floor, and 2DY to 8DY are circuits to determine whether to release a call from the 2nd to 8th floors.

Since the elements constituting the above circuit can be easily constructed using conventional techniques, detailed explanation thereof will be omitted.

Next, the operation of this embodiment will be explained.

Assume now that a call has been registered as shown in FIG. 1, and car a has arrived at the seventh floor in the ascending direction.

When the 7th floor ascending call 7a does not have the reset condition described later, pressing the 7th floor ascending button causes the 7th floor ascending button signal 7UB to become rHJ, sets the memory element 7U1, and sets the 7th floor ascending call registration signal 7U as " It is registered as "H".

The same applies to other hall calls. When car a arrives at the 7th floor in the ascending direction, both the 7th floor car position signal 7F and the ascending operation signal 11 of car A become rHJ, and the 7th floor ascending call assignment signal 7UA
Or, if the 7th floor car call registration signal 7CC is rHJ, the 7th floor ascending arrival signal 7US is set to "H" through AND gates 7U10 and 7U11, and a stop decision is made.

Let us consider the case where car a is assigned to the 7th floor ascending call 7a.

Since the 7th floor ascending call assignment signal 7UA of machine A is rHJ, it is decided to stop.

At this time, since the above assignment signal 7UA is inputted to the computer A circuit 7U12 with the level reversed through the computer game 7U11, the 7th floor ascending call cancellation prohibition signal 7UN of the computer A is rLJ.

In addition, since the 7th floor ascending call is not assigned to other machines, the 7th floor ascending call assignment signal 7UA of the B and C machines is rLJ, and the 7th floor ascending call cancellation prohibition signal 7UN is also "L".
becomes.

Therefore, the 7th floor ascending arrival signal of Unit A 7 US -
Since a is rHJ, the output of (or game) 7U2 becomes "H".

In addition, the 7th floor ascending call cancellation prohibition signal 7UN-a of A-C
~ Since all 7UN-C are rLJ, the output of or game) 7U3 becomes "L", so and game) 7
The output of U4 becomes "H", the memory element 7U1 is reset, the 7th floor ascending registration signal 7U becomes rLJ, and the 7th floor ascending call is canceled.

At this time, the 7th floor ascending call assignment signal 7UA also becomes rLJ, and there is no advance notification, but an arrival notification.

The circuit is omitted. Next, let us consider a case where, although it is the A-car that has arrived at the 7th floor in the ascending direction, the aircraft that is assigned to the 7th-floor ascending call 7a is the B-car that is operating on the 5th floor in the ascending direction.

It is believed that Car A had a car call on the 7th floor.
As mentioned in the previous example, the 7th floor climbing arrival signal 7US is rHJ
becomes.

Since car B is currently operating in the ascending direction on the 5th floor, the 5th floor car position signal 5F and the ascending operation signal 11 become rHJ, and the gate circuit 5U6 is reset.

Although this is not directly shown in the figure, it can be easily understood if it corresponds to the seven-story ascending direction circuit in FIG.

Fig. 3 is shown for machine A, but when considering machine B, the 7th floor ascending arrival signals 7US-b and 7US-c as inputs are used as signals 7US for cars other than B.
-a, 7US-C (same for other floors and directions)
However, everything else can be the same as Unit A.

Since car No. B has a car call 6b on the 6th floor, the 6th floor car call registration signal 6CC becomes rHJ and is inputted as 1 to the adder 6U5.

The other input of the adder 6U5 is the output 5U6A of the gate circuit on the 5th floor, and since the gate circuit 5U6 on the 5th floor has been reset as described above, its output 5U
6A becomes zero.

Therefore, the output of the adder 6U5 becomes 1, the gate circuit 6U6 is not reset because the 6th floor car position signal 6F is "L", and the output 6U6A becomes 1.

On the 7th floor, the 7th floor ascending call assignment signal 7UA is rHJ, so 1 is added to the output 6U6A of the 6th floor gate circuit in the same way as above, and the output cuff U6A of the 7th floor gate circuit becomes 2.

In this way, the outputs of each gate circuit IU6A to 7U6A, 8
D6A to 2D6A are located between the floors where the car is located in the direction O, and indicate the number of floors where there is an assigned hall call or a car call ahead in the direction of travel of the car.

As can be seen in Figure 3, the forward direction of operation means, for example, in the case of going up the 5th floor, going up the 6th floor → going up the 7th floor, going down the 18th floor → ... going down the 2nd floor, going up the 11th floor →... ...It will be like climbing four floors.

Now, when the output cuff U6A of the gate circuit on the 7th floor is 2 and the constant value signal 13 is 3, the output of the comparator 7U7 becomes "H".

The 7th floor ascending arrival signal of Unit A, 7 US-a, was interrupted.
H'', the 7th floor ascending call assignment signal 7UA is rHJ, and the 7th floor car position signal 7F is rI, J, so the OR gate 7U8, the AND gate 7U10. Through t7U11.7U12, the 7th floor ascending call cancellation prohibition signal 7UN becomes rHJ.

Therefore, the 7th floor ascending arrival signal of Unit A 7 US -
Even if a becomes rHJ, the output of AND gate 7U4 is
H" and the 7th floor ascending call is not reset.

In this case, even if you don't get on the A car that arrived earlier, the predicted B car will arrive in a short time, so you can make the 11th line of the forecast without resetting the landing call, indicating that you can wait for the B car. It is.

In the end, it was plane A that arrived on the 7th floor in the ascending direction.
Let us consider a case where the aircraft assigned to the 7th floor ascending call is Aircraft C, which is operating in the ascending direction on the 1st floor.

As mentioned above, the output cuff U6A of the gate circuit for the 7th floor ascending direction of the C car is the 3rd, 4th, and 5th floor where the assigned call or call for the C car between the 1st floor crossings is. , there are 7th and 4th floors, so it is 4.

Therefore, the output of the comparator becomes "L" and the 7th floor ascending call cancellation prohibition signal 7UN-C of car No. C becomes "L".

Unit A went up to the 7th floor, arrival signal 7 U S -a was r
Because it becomes HJ, the canceled B machine sends the 7th floor ascending call assignment signal 7U.
Since A becomes "L", both 7th floor ascending call cancellation prohibition signals 7UN-a and 7UN-b become "L".

Therefore, in the end, the 7th floor ascending arrival signal of Unit A 7 U S
-a becomes rHJ and the 7th floor ascending call is reset.

In this case, since it is predicted that the predicted flight number C will be considerably delayed, the hall call is canceled in order to encourage passengers to board the train number A, which arrived earlier.

In the above example, when a car that has not been predicted arrives, the arrival time of the predicted (allocated) car is estimated based on the expected number of stops for that car, and if the value is small, the hall call is canceled. However, the above arrival time may be estimated by other means, for example, from mere floor spacing, or it is expected that the arrival time will occur during operation at a short destination floor. It is also possible to estimate by considering calls probabilistically.

In addition, in the embodiment, the value for determining whether or not to cancel a hall call is constant for each floor, but it may be made different depending on the floor, or may be changed depending on the traffic condition.

Furthermore, in addition to call cancellation, a device may be provided that displays, when an unassigned car arrives, whether the assigned car will arrive within a short time.

Furthermore, if the allocated car is already full and the car passes through that landing, or if a car other than the allocated car is expected to arrive first after the unassigned car arrives, or if the allocated car is If the call becomes unmanaged, the hall call may be canceled regardless of the conditions described in the above embodiment.

As explained above, in this invention, when a serviceable car arrives at a hall call other than the car for which advance notice has been given, and when the expected arrival time of the forewarned car is longer than the predetermined time, the hall call Since this feature is released, passengers waiting at the landing can accurately know whether or not they should board the car that arrived first.

Furthermore, it is possible to prevent waiting times from becoming extremely long and provide good service to passengers.
