Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for predicting the arrival of an elevator car at a landing.

At the elevator landing, as shown in Fig. 1, a landing button 2 is installed between adjacent landing entrances 1, and arrival warning lights 3, 4 for ascending and descending directions are installed above the entrance 1. .

Further, in addition to the lighting of the arrival forecast lights 3 and 4, an alarm 5 such as an arrival forecast gong and an arrival forecast chime that predict the arrival of a car by sound is installed.

When a waiting passenger at the hall presses the exit button of the hall button 2, the call is registered.

When the car decides to respond to this call, the arrival warning light 4 lights up and at the same time the alarm 5 sounds once to notify that the car will arrive soon.

However, the arrival forecast light 4 lights up and the alarm 5 sounds (hereinafter, these are collectively referred to as the arrival forecast).

) The timing becomes earlier as the difference between the position of the elevator car and the position of the floor to be stopped becomes larger.

In other words, in Fig. 2, 6 to 8 are speed characteristic curves for the car to stop at the 1st floor, and 6 is the speed characteristic curve for the car to stop at the 1st floor. When issuing a stop command at decision point 6a and moving to deceleration, 7 starts from the 10th floor, and when issuing a stop command at stop decision point 17a near the 6th floor and moving to deceleration without reaching the maximum speed, white is the same. A case is shown in which the vehicle starts from the fourth floor, issues a stop command at a stop decision point 8a near the third floor, and moves to deceleration.

Conventionally, the above arrival forecast commands are from stop decision point 63 to
8a, there is a considerable time difference between them.

Since the acceleration/deceleration of the elevator is almost determined by human physiological problems, this time difference becomes larger as the speed at the deceleration point of the elevator is higher.

In other words, the time it takes from when the arrival forecast is issued to when the car arrives varies greatly depending on the distance traveled by the car from when it starts to when it stops.

When the speed exceeds 500 m/·, there are cases where the train arrives immediately after the arrival forecast is issued, and cases where it takes more than ten seconds.

As a result, passengers waiting at the landing are forced to wait for more than ten seconds after the arrival forecast is issued, making them feel extremely irritated.

In addition, if the arrival forecast is issued several seconds in advance, people who arrive late at the boarding point will have fewer chances to hear the warning horn 5, and the arrival forecast light 3
, 4 alone is necessary to notify the arrival of the car, the function of the alarm 5 is not fully fulfilled.

Therefore, in the worst case scenario, it cannot be said that a person who arrives late at the boarding point will miss the arriving car.

This invention solves the above-mentioned drawbacks by operating the arrival warning lights, alarms, etc. that predict the arrival of an elevator car at a later time than when the car has decided to stop. To provide an arrival forecasting device which can relieve the feeling of impatience of passengers waiting at a landing by keeping the time until arrival of passengers constant, and can sufficiently exhibit the function of arrival forecasting.

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

In the figure, reference numeral 10 indicates a stop command signal issued at the stop decision points 6a to 8a shown in FIG.
b, timed signal 11c after 3 seconds, timed signal 1 after 4 seconds.
1a respectively, and is reset by a signal 12 to be described later; 12 is a door-closing signal that is emitted when the car has stopped and the door has opened; and the door has been closed halfway after passengers have boarded and alighted; and 13 is a door closing signal for the car. This is a call position signal issued from a floor selector (not shown) that simulates movement, and is issued in response to a called floor for which the car has been determined to stop.

Reference numeral 14 is a car position signal also generated from the floor selector, which is generated in accordance with the car position.

15 is a signal 13. when the stop command signal 10 is input.
14, calculate the floor difference between the floor where the call has been decided to stop and the floor corresponding to the car position, and when the floor difference is the 8th floor, the floor difference signal 15a is generated, and when it is the 7th floor, the floor difference signal 15b is generated. Floor, 5
Floor difference signals 15c to L5 for floors and 4th floor and below, respectively
an arithmetic unit which emits e and stores them and is reset by a signal 12; 16 to 19 are AND gates; 20 is an O
R gate, 21 is a downward direction signal which is provided while the car is running in the downward direction, and 22 is an AND gate.

Assuming that the car is currently descending, a descending direction signal 21 is being generated.

When the car starts from a distant floor, travels along the curve 6 in FIG. 2, and decides to stop at a stop decision point 6a, a stop command signal 10 is issued.

The timer 11 emits the timer signal 11a one second after the signal 10 is input, the timer signal 11b after 2 seconds, and the timer signals 11 c and 11 after 3 and 4 seconds, respectively.
emit d.

At the same time, when the signal 10 is input, the calculation device 15 calculates a floor difference corresponding to the difference between the position of the car and the position of the call to be stopped.

Since the floor difference at this time is 8 floors as is clear from FIG. 2, a floor difference signal 15a is generated and input to the AND gate 16.

The floor difference signal 15a is stored and the other floor difference signals 15b to 15e
will no longer be emitted.

When timed signal 11d is issued four seconds after signal 10 is issued, AND gate 16 issues an output, which is input through OR gate 20 to AND gate 22.

Since signal 10 and signal 21 have already been input,
The AND gate 22 emits an output, the arrival warning light 3 lights up, and the alarm 5 sounds to warn waiting passengers at the landing of the arrival of the car.

When the car arrives at the landing and the door is opened, and the door is closed halfway after passengers have boarded and alighted, the door closing signal 12 is issued, the timer 11 and the computing device 15 are reset, and the signal 11
a to 11d and signal 15a disappear, AND gate 1
6, that is, the output signal of AND gate 22 disappears.

Arrival Forecast 3 is now off, and alarm 5 does not sound continuously, so it is irrelevant.

) Return to initial state. Next, when the car that started from the 10th floor travels along the curve 7 in FIG. When the 2 second time signal 11b is issued, the AND gate 18 issues an output and performs the same arrival forecast as described above.

Further, when the car that has started from the 4th floor decides to stop at the stop decision point 8a of the curve 8 in FIG. Arrival forecast will be made.

In this way, when the floor difference between the car and the called floor is 8 floors, that is, when the speed is high, 4 seconds after the decision to stop is made, and when the floor difference is 7 floors, 3 seconds after the floor difference is reached. If the car is on the 6th floor, the arrival forecast will be issued 2 seconds later, if the floor difference is 5th floor, it will be 1 second later, and if the floor difference is 4 floors or less, the arrival forecast will be issued immediately, so from the time the arrival forecast is issued until the car arrives. The time period can be approximately the same (for example, 4 to 6 seconds) in both cases.

Therefore, passengers can always wait for the arrival of their cars with the same feeling.

Note that the timer 11, arithmetic device 15, etc. shown in FIG.
Any forecast command device that emits an output signal at a time of 6 seconds) may be used.

It goes without saying that a similar function can also be obtained by using only the calculation device 15 to forecast the arrival when the difference between the position of the landing area to be stopped and the position of the car is less than a predetermined value. .

Although the above embodiment has been described for the case of descending travel, it is clear that the same applies to the case of ascending travel.

As explained above, the present invention operates a forecaster that predicts the arrival of a car at a later time than when the car decides to stop at the landing, or when the distance until the car arrives at the landing reaches a predetermined value. I set it to work when it reaches
The arrival forecast is made at a fixed time before the arrival of the car, regardless of the departure position, speed, etc. of the car, so that passengers' sense of impatience can be alleviated, and the arrival forecast function can be fully utilized.
