2. Description of the Related Art In the operation of an elevator, a control signal for moving a car from a departure floor to a destination floor is created by operating an operation button installed in a car or an elevator hall. Based on the above, the raising / lowering operation of the car is controlled.

When the destination floor to be stopped next is determined, the elevator car elevator control is performed based on the operation patterns shown in FIGS. 6 to 8. That is, when the moving distance to the destination floor is long and the car reaches the maximum speed, 0 to t1 is set with the moving start time of the car as the origin as shown in FIG.
During the period of, the vehicle accelerates with a constant acceleration, which causes the velocity to increase linearly and reach the maximum velocity. Next, during the period from t1 to t2, the maximum speed is maintained and constant speed movement is performed. Then, during the period from t2 to t3, the vehicle is decelerated at a constant acceleration, the speed is linearly reduced by this, and the car stops at time t3.

As the moving distance to the destination floor becomes shorter, the above-mentioned constant velocity period (t1 to t2) becomes shorter.
As shown in, there is no constant speed period, and the car accelerates to the maximum speed and then decelerates. When the moving distance becomes shorter, deceleration starts before reaching the maximum speed as shown in FIG. The travel distance of the car is determined by the distance between floors of the building. Therefore, if the travel distance to the destination floor is long, adjust the length of the constant speed period (t1 to t2) and if the travel distance is short, Adjusts the length of the acceleration period (0 to t1, t2 to t3) and stops at the destination floor.

Therefore, the distance between floors, the acceleration of the car,
If the maximum speed is determined, the travel time (0 to t3) is uniquely determined. For example, in a 10-floor building, if the distance between floors is 4 m, the travel distance of the car from any departure floor to any destination floor can be expressed as shown in FIG.
Furthermore, the maximum speed is 2 m / sec and the acceleration is 0.4 m / s.
Assuming ec ² , the travel time corresponding to FIG.
It becomes like.

In actual elevator control, the acceleration is not constant, and in order to reduce shock and discomfort at the start of acceleration and the start of deceleration, an acceleration pattern as shown in FIG. 9 is adopted to smooth the speed. A device to change to is made. Also in this case, the travel time can be uniquely determined as in the case of FIG.

By the way, in recent elevators,
It has been proposed to install an image display device in the car to display environmental images and textual information in order to relieve tension between passengers or to accurately convey information to passengers. 3-182489).

[0008]

However, in the conventional elevator system in which the image display device is installed in the car, the displayed image is not always complete when the car stops at the destination floor. , Passengers who are interested in the contents of the video may overtake the destination floor to see the video to the end. As a result, there arises a problem that the utilization efficiency of the elevator is reduced. In addition, the elevator is congested, which gives passengers an unpleasant feeling. Furthermore, if there is no new passenger arriving at the destination floor, a passenger who wants to see the image to the end may continue to press the button for opening the door, which causes other passengers to enter the other floor. In the elevator hall, there will be a problem that service will be delayed for users waiting for the arrival of the elevator. The same problem also occurs in an elevator system in which a speaker is installed as a voice output device in a car.

An object of the present invention is to provide an elevator system in which the video and audio broadcasting is completed when the car stops at the destination floor, and solves the above problems all at once. is there.
