Description

Description: TECHNICAL FIELD The present invention relates to a congestion situation of an elevator waiting person who fills an elevator hall by image processing of video information captured by a television camera, and determines the elevator according to the determination. The present invention relates to an elevator device that is designed to perform operation control.

2. Description of the Related Art In recent years, with the increasing use of buildings and other applications, it has been required to improve the transportation efficiency of a large number of people or objects. It is hoped that floor movement will take place.

In the conventional elevator in a building, a waiter who came to an elevator hall where multiple elevators are adjacent to each other has one of the basket call buttons arranged on the hall wall corresponding to each elevator. When pressed and lit, the computer that controls the operation of the system receives the signal, and all the elevator car call buttons in the hall on the floor are lit up at the same time. Is checked and one of the most suitable baskets is selected, and the control is performed so as to lead to that floor. As soon as the baskets arrive on the floor, the basket call buttons are turned off all at once, and the basket calls are canceled.

Problems to be Solved by the Invention However, in such an elevator system,
The number of baskets placed by one waiting call by one passenger is one, and if many passengers gather in the hall, the passengers who are left unloaded must press the basket calling button again. there were. In order to solve this problem, it is considered to notify the computer that there are a lot of waiting customers by the number of times the call button is pressed, and to arrange multiple baskets, but this method does not have the actual congestion degree. Is not fully understood. That is, in general, the pressing and lighting of the car call button is performed by the car call of the first customer who arrives, and it does not disappear until the selected elevator arrives at the hall. Is something you don't do much. Further, in some cases, one passenger may press the call button multiple times.

Means for Solving the Problems An elevator apparatus according to the present invention is a video memory for predictively storing a video signal captured by a television camera disposed in the elevator hall within a predetermined range when there are no waiting passengers in the elevator hall. Means and the image information signal of the elevator waiting customer who fills the predetermined range imaged by the television camera with the image information signal stored in the image memory means, and the area where the luminance change occurs is the area. Brightness change detection means for generating a detection signal including information indicating,
The detection signal from the brightness change detecting means as a satisfaction signal corresponding to the waiting customer satisfaction rate of the elevator hall, the waiting customer satisfaction degree determining means that outputs in conjunction with the operation of the call button, and the basket according to the satisfaction signal. It is composed of an elevator operation control device that determines the number of vehicles.

Action According to the above configuration, since the number of waiting passengers is determined based on the change in the video signal of the elevator hall, an appropriate number of baskets can be provided to the hall depending on the congestion of waiting passengers in the elevator hall. It can be arranged, even if many people gather in the elevator hall,
There is no leftover due to one basket call,
It is possible to eliminate traffic congestion and waiting time loss, and to achieve smooth floor movement.

Example Hereinafter, an elevator apparatus of the present invention will be described with reference to the drawings. FIG. 1 is an electrical block diagram of an elevator apparatus according to an embodiment of the present invention, in which a video camera 1 is picking up an image of a predetermined area of an elevator hall, and its video signal is sequentially converted into a digital signal by an AD conversion circuit 2. To be done. The image memory 3 is for pre-storing the image information by the camera when there are no customers waiting, and when the switch 3a is turned on, the image when there are no customers waiting is stored in advance. During operation, the brightness change detection means 4 compares the image information in the current elevator hall converted into the digital signal with the image information in the absence of waiting passengers stored in the image memory 3, and the current elevator hall is compared. The rate of change of the luminance of is detected. That is, as shown in FIGS. 2A to 2C, a which is image information when there are no passengers and luminance information b at a certain time point,
c is compared. The total area of the areas where the respective brightnesses have changed represents the degree of congestion of waiting passengers in the elevator hall, which will be hereinafter referred to as a waiting passenger satisfaction rate. Here, waiting passengers may not always stay at the same position but may move, but even if they move, the congestion degree is constant if there is movement within a predetermined area, and there is no error in detection. is there. However, if the layout of the elevator hall leads to the passage that connects the rooms to each other, people who pass through the hall to another place will also detect it with the waiting passengers. It is conceivable that an error may occur due to. Therefore, in this embodiment, the waiting customer satisfaction rate detected by the brightness change detecting means 4 is averaged over a predetermined time period (for example, 10 seconds) by the waiting customer satisfaction determining means 5, and the average value is calculated. Several types of outputs corresponding to the satisfaction signals are output in association with the operation of the call button 6 and applied to the next elevator operation control device 7.

In the elevator operation control device 7, the number of baskets that can respond to the satisfaction signal is determined in advance. For example, when the total number of elevators in the hall is 8, the waiting number read from the waiting passenger number determination means 5 is read. One when the customer satisfaction rate is 1-24%, two when the customer satisfaction rate is 25-49%, three when the customer satisfaction rate is 50-74%, 75
When it is ~ 100%, we arrange 4 cars and lead them to the hall.

That is, as shown in FIG. 2, the video information a when there are no customers waiting,
By comparing the video information b and c at each certain point of time with the brightness change detecting means 4, the waiting customer satisfaction rate is detected, and in the case of b, one car is arranged with a satisfaction rate of 40%,
In the case of c, three cars are arranged with a fill rate of 60%.

Effects of the Invention As described above, the elevator apparatus of the present invention can arrange the number of baskets in the hall according to the congestion of passengers in the elevator hall. It eliminates this and enables smooth lower movement.
