Description

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

When you press the Hataba button installed in the Hataba area of the elevator, a Hataba call is registered, and you can use this call to summon your car. When the car approaches that floor, an arrival forecast light installed in the front yard is turned on to indicate to waiting customers that the car will soon arrive and the direction in which the car will be driven. When the car arrives, the door opens and passengers can enter and exit. When the door begins to close, the arrival warning light goes out, and once the door is closed, the car departs. In this way, since the arrival forecast light is on when the door is quiet, it is quite possible that the arrival forecast light will still be on even when the car is full.

As a result, there was a problem in that other passengers were unnecessarily guided and they were unable to board the car, and these passengers also prevented the car from closing, causing a delay in the departure of the car. Furthermore, when multiple cars are installed in parallel, some of them may be stopped on the same floor with the same direction of operation.

At this time, the arrival warning light corresponding to each car is naturally lit, so the waiting passenger tries to board one of the cars. However, if that car is full, you will not be able to board the car, and you will have to move to board another car, but in the meantime, that car will also close its door and depart, meaning that you will not be able to board any car. become. Even in the case of a delayed flight, passengers were sometimes unable to board the train even though the arrival warning light was on, creating a sense of distrust among the passengers.

The present invention aims to improve the above-mentioned problems, and provides an arrival forecasting device for an elevator Hataba, which appropriately selects the timing for turning off the arrival forecasting light and prevents unnecessary guidance of waiting customers when the car is full. With the goal.

Hereinafter, an embodiment in which the present invention is applied to a third-floor Hataba will be described with reference to FIG.

In the figure, 1 is a car position signal that becomes "1" when the car reaches the position where it can properly decelerate and stop on the 3rd floor, and 2 is a stop command signal that becomes "1" when the car in the upward direction decides to stop. ,
3 is a door closing start signal that becomes "1" when the car door starts to close, 4 is an in-car load detection device that outputs "1" when the load in the car exceeds a predetermined value (for example, full), and 5 is an in-car load detection device. AND
The gate, 6 is the arrival warning light installed on the third floor landing, and 7 and 8 are inverters.

Currently, the load inside the car is light and the car is operating in the up direction.
When it is decided to stop on the floor, the car position signal 1 and the stop command signal 2 become "1", and the output of the load detection device 4 becomes "0".
Then, the output of the inverter 8 becomes "1".

Further, since the door closing start signal 3 is "0", the output of the inverter 7 is "1". Now, all the inputs of the AND gate 5 become "1", its output becomes "1", and the third floor uplight 6 lights up. This indicates that the car traveling in the upward direction will soon arrive at the third floor. 3 baskets
When the passenger arrives at the floor, the door opens, the waiting passenger gets on board, and the door begins to close, the door closing start signal 3 becomes "1" and the output of the inverter 7 becomes "0". Therefore, the output of the AND gate 5 also becomes "0", and the up light 6 is turned off. Once the door is closed, the car departs. Next, when the above-mentioned car arrives at the third floor and a waiting passenger gets in while the door is open, the load inside the car exceeds a predetermined value.
The output of the load detection device 4 is ``1, the output of the inverter 8 is ``
0". As a result, the uplight 6 on the third floor is turned off, indicating that it is no longer possible to get into the car. Therefore, the passengers waiting at the Hataba on the 3rd floor and those who have arrived at the Hataba will not be in a hurry to get on board because the arrival forecast light is off, and they will not be distrustful of the passengers. It doesn't give a feeling. Also, the departure of the basket will be smooth. Figure 2 shows another embodiment of the present invention, in which the door closing control signal 101 becomes "1" after an appropriate period of time has passed after the elevator door opens, 11 is an OR gate, and 11a is the output of the OR gate. This is the door close command signal.

The rest is the same as in FIG. When the load inside the car is light, when the door closing control signal 10 becomes "1", the output of the OR gate 11 also becomes "IJ", and the door closing command signal 11a also becomes "1", so that the door closes.

When the load in the car exceeds a predetermined value and the output of the load detection device 4 becomes "1", the uplight on the third floor is turned off as explained in FIG.

At the same time, the door close command signal 11a also becomes "1" through the OR gate 11, and the door closes. In other words, when the car is full and no passengers can board, the arrival warning light is turned off and the doors are closed early to allow the car to depart, increasing operational efficiency. Although the above embodiments have been described with respect to up lights, the same can be applied to down lights, and can be implemented in the same way on each floor.

As explained above, in this invention, when the load inside the car exceeds a predetermined value, the arrival warning light is turned off even if the door is open, indicating that no one should get into that car. Therefore, the departure of the cars can be arranged in a timely manner without giving the passengers any sense of disbelief that they have missed their boarding.
