Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for notifying a car that is servicing a hall call before the car arrives.

When a call is registered at an elevator landing, it has become common practice to use an arrival warning light or the like to notify the car that is expected to respond to the call before the car arrives.

Usually, it announces whether one device has been assigned to respond (hereinafter referred to as the assigned car).

However, the entrance floor at the time of dispatch, the floor where the lunch cafeteria is at lunch time,
At the end of the meeting, a considerable number of passengers will gather at the elevator landing on the floor where the meeting room is located.

In a system where only one car is in service, in such a case, even if passengers gather in front of the car that is being serviced, not all of them will be able to board the car.

Therefore, customers who have given up on not being able to ride are forced to wait impatiently, not knowing which car they can ride.

Also, when one car arrives and the next car is announced, passengers will gather in that car again, but in this case, passengers who arrive at the elevator hall first will have priority in boarding that car. It's easy to feel frustrated that it's not always fair.

On the other hand, methods have been considered to always notify multiple cars or to notify all assigned cars, but it is difficult to notify multiple cars even when the landing area is not crowded. This creates confusion for waiting passengers, as it is unclear which car they should board, and is not good for overall operational efficiency.

Also, if a call has been registered for a long time, calls on a specific floor will be answered preferentially, so even if multiple cars are designated to be serviced, it would be better to notify only one car.

Furthermore, even if there is a slight possibility that the car will be full, it is not a good idea to notify multiple cars because it will not be known until the car arrives.

This invention aims to improve the above-mentioned drawbacks, and aims to provide a notification device that provides friendly guidance to passengers waiting at the landing.

An embodiment of the present invention will be described below with reference to the drawings.

Here, there is a meeting room on the 9th floor of a 10-story building, and at the end of the meeting, the elevator hall is assumed to be full with passengers descending from the 9th floor.The figure shows a circuit that notifies whether there is a service going down to the 9th floor. show.

In the figure, 1A to 1C are the 9th floor downbound car position signals that are rHJ when the cars A to C arrive at the 9th floor in the downhill direction, and 2A to 2C are the 9th floor downbound car position signals that are "H" when the doors of each car are closed.
”, 3A to 3C are stop signals that become rHJ when each car is stopped, 4A to 4C are heavy load signals that become rHJ when the load in each car becomes 80% or more of a predetermined value, 58 to 5C are light load signals that become rHJ when the load in each car is less than the predetermined value of 40, and 6A to 6C are 9
An assignment signal that becomes rHJ when a car is assigned to a downstairs call; 7A-IC is an expected waiting time signal indicating the expected waiting time in the direction of going down the 9th floor when each car responds to a 9th-floor downcall; 8A- 8C is a notification signal that becomes rHJ when notifying the 9th floor landing that each car responds to the 9th floor alighting call, 1
1A to 11C212A to 12C, 13A to 13C are AND gates, 14.15 is an OR gate, 16 is set when the S side signal is rHJ, and the output signal is rHJ, and S
This is a memory circuit that is reset when the side signal is rLJ and the R side signal is rHJ, and the output signal is rLJ.
The OR gates 14, 15 and the word/go circuit 16 constitute a congestion level detection circuit.

17A to 17C are when the input signal marked G is rHJ,
The value of the signal entering from the left side is output as is, and the input signal is r
In the case of LJ, a gate circuit outputs a very large value, for example "999", and 18 is a minimum value calculation circuit which sets the output signal corresponding to the input line with the smallest value among the input signals to "H". If the signal value of the line located at the top of the diagram among the signals is the minimum, only the signal of the line located at the top of the diagram among the output signals is set as rHJ.

19A-19C are inhibit gates, 20A-20C are OR gates, 21A-21C are gates, and gate circuits 17A-
17C1 Minimum value calculation circuit 18, inhibition gates 19A to 19
C1 or gate 20A-20C and Antogame-1-21
A to 21C constitute a notification signal generation circuit.

Assume that the meeting room floor (9th floor) is not crowded now.

Normally, only one car is assigned to a call to get off the 9th floor, but if that call has been kept waiting for a long time, car
Assume that both cars are assigned to car B.

Since the assignment signals 6A and 6B are "H" and the assignment signal 6C is rLJ, the gate circuit 17A.

17B outputs the input signal from the left side as it is, and outputs the input signal from the left side as is.
The output circuit 17C outputs 999 seconds.

If the value of the expected waiting time signal 7A for car A is 40 seconds and the value of the expected waiting time signal 7B for car B is 30 seconds, then among the output signals of the minimum value calculation circuit 18, the one related to car B, that is, the prohibited gate. Only the signal input to 19B becomes rHJ.

If it is not crowded, the output of the memory circuit 16 will be rLJ (this will be explained later).

), the output of the inhibition circuit 19B becomes rHJ, and the notification signal 8B becomes "
H”.

Therefore, car B will be notified.

The other cars are not notified because the inputs of the OR gates 20A and 20C are both rLJ.

Next, consider a case where the meeting room floor (9th floor) is crowded.

Now, when car C arrives at the 9th floor in the direction of descent, picks up a passenger, and closes the door, the 9th floor alighting car position signal IC1 door close signal 2C
, stop signal 3C both become "H", so the Antogame N
The output of the IC becomes rHJ.

At this time, the load in the car exceeds the predetermined value of 80 coefficients,
When the heavy load signal 4C becomes rHJ, Antoge-N2C,
The memory circuit 16 is set through the OR gate 14.

In this case, the outputs of the OR gates 20A to 20C will all become "H", and all the cars whose assignment signals will be "H" will be notified.

If the assigned cars are car A and car B, the notification signals 8A and 8B become rHJ via AND gates 21A and 21B.

The memory circuit 16 is reset when one car is loaded with less than 40% of the predetermined value and the door is closed.

For example, if it is car A, the 9th floor down car position signal I A, the door close signal 2 A, the stop signal 3 A, and the light load signal 5 A.
are all "H", and Antogame hllA.

The output of OR gate 15 becomes "H" through 13A, and the memory circuit 16 is reset.

In this way, if both cars A and B are allocated, if it is not crowded, only one car, B, which is expected to arrive first, will be allocated, and if it is crowded, car A will be allocated.
This means that both the car and the car B are notified, that is, all the cars that have been broken.

In this embodiment, the allocation signals 6A to 6C and the expected waiting time signals 7A to IC have been described as well-known signals, but they can be determined by, for example, the following equations.

〈Estimated waiting time〉 = 〈Floor spacing between the landing and the car for which waiting time is to be calculated〉 x 〈Average travel time per floor〉 + Number of floors to be expected〉×〈Average stopping time per floor〉+〈Registered time of calls registered at the above landing〉〈Allocation〉−〈When the minimum value of expected waiting time is less than a predetermined value,
Only the car with the minimum expected waiting time is "H"; when the expected waiting time is equal to or greater than a predetermined value, the car with the second smallest expected waiting time is also "H"> Furthermore, the determination of the degree of congestion is not limited to the method described in this embodiment.

If you want to make an accurate determination, it is necessary to use a detection device for the number of passengers waiting in the hall.

Furthermore, instead of notifying one of the allocated cars when it is not crowded and all allocated cars when it is crowded as in this embodiment, when the notification is not desired for other reasons, For example, if the expected waiting time is greater than or equal to a predetermined value, the notification may not be made even if the conditions of this embodiment are satisfied.

As explained above, in this invention, the number of cars selected to serve the hall call is notified according to the congestion level of the hall, so it is clear to the passengers waiting at the hall which car they should board. be able to give instructions and provide friendly service.
