Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator control device that controls which floor each elevator is moved to when operating an elevator or other elevator to each floor. .

(Prior Art) FIG. 3 is a diagram illustrating the control operation of a conventional elevator control device of this type. The elevator 1.2 moves up and down between the 1st to 6th floors in the building, picks up passengers waiting at each floor, and moves to the floor designated by the passenger. Here, the conventional elevator control device 3 performs control to move the elevator 1 or 2 to the requested floor in the order of requests for elevator movement from passengers waiting on each floor, and transport the passengers to the desired floor. Is going. Therefore, now
If a passenger waiting on the 6th floor requests elevator movement first, elevator 2 will first be moved to the 6th floor, and then elevator 2 will be moved to the 6th floor.
After picking up another passenger, 5P! The plane then descends to pick up three more passengers. The maximum capacity of this elevator is five people, and all five people who board the elevator on the 6th and 5th floors will get off on the 1st floor.

Therefore, since the elevator 2 is full on the 5th floor, it passes through the 4R1 and 3rd floors and descends only once. After the elevator 2 has passed by even though there are passengers waiting on the 4th and 3rd floors, the controller 3 moves the elevator 1 to 4 to pick up the passengers on the 4th and 3rd floors.
After ascending to the fourth floor and picking up one passenger, it descends three times to pick up three more passengers before descending to the first floor. However, all passengers waiting on the 4th and 3rd floors will also get off on the 1st floor.

As in the example above, if many passengers are waiting on relatively high floors such as the 6th and 5th floors, the upper floors will be filled with passengers waiting on lower floors such as the 4th and 3rd floors. The downside was that it was difficult to get on the elevator and get down. Such a drawback is that the elevator control device 3 cannot know in advance the number of passengers waiting on each floor, so the elevator 1.2 cannot be operated efficiently and the waiting time for passengers, especially those on the lower floors, becomes longer. There is a high probability that you will not be able to get down to the lower floor.
It is thought that it will happen.

(Problems to be Solved by the Invention) As described above, the conventional elevator control device does not know in advance the number of passengers waiting on each floor, so if there is a request to move the elevator to a higher floor, the elevator will first be moved. After ascending to the requested higher floor to pick up passengers, the elevator descends to lower floors in order to pick up passengers, so there is a high probability that the elevator will be full on a relatively high floor, and a low Even if there are passengers waiting on the floor, there are a lot of people who don't stop and end up passing them. Therefore, passengers waiting on a lower floor have to wait until another elevator moves after the elevator has passed, making it difficult to get down. This is because the elevator control device 3 cannot know in advance the number of passengers waiting on each floor, making it impossible to operate the elevator efficiently.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks, and enables efficient operation of the elevator by determining the number of passengers waiting on each floor in advance and determining the number of floors and course to which the elevator will be moved based on the results. The purpose is to provide an elevator control device that can perform

[Structure of the invention]

(Means for Solving the Problems) The present invention provides an elevator control device that operates an elevator to each floor and carries passengers, luggage, etc. on each floor to a desired floor. means, an image processing means for analyzing image information obtained from the imaging means, and elevator drive information for controlling the floor to which the elevator is first moved and the subsequent operation course based on the analysis result of the image processing means. and a control information creation means for creating the control information.

(Function) In the elevator control device of the present invention, the imaging means captures image information of each floor. The image processing means analyzes the image information obtained from the imaging means. The control information creation means creates elevator drive information for controlling the floor to which the elevator is first moved and the subsequent operation course based on the analysis result of the image processing means.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings, in which the same parts as those of the conventional example are denoted by the same reference numerals. FIG. 1 is a diagram showing an embodiment of an elevator system equipped with an elevator control device of the present invention. 1.2 is an elevator that ascends and descends between each floor from the 1st floor to the 4th floor; 3 is an elevator control device that controls the movement of the elevator 1.2 according to the number of passengers waiting on each floor; 41 to 4- Reference numeral 4 indicates an infrared camera provided on each of the 1st to 4th IP floors, and 5-1 to 3-4 indicate elevator movement request buttons provided on each of the 1st to 4th floors.

FIG. 2 is a block diagram showing a detailed example of the elevator control device 3 shown in FIG. 1. 31 is CP which is the center of device 3
32 is an interface for inputting infrared image information from the cameras 4-1 to 44 to the CPU 31;
34 is an image processing unit that processes the input infrared image information to analyze the number of passengers waiting on each floor; 34 is an image processing unit that carries the passengers to the desired floor in the most efficient manner based on the number of passengers waiting on each floor; A memory 35 stores an elevator operation table showing the movement method of the elevator 1.2 for
The elevator movement or stop control signal from 1 is sent to the elevator drive unit 3.
6, 36 is the elevator 1
．． 2 is an elevator driving section that drives the elevators 2 and 2 independently based on control signals from the CPU 31.

Here, the infrared cameras 4-1 to 4-4 serve as imaging means, the image processing unit 33 serves as image processing means, and the CPU 31 and memory 3
4 constitutes control information creation means.

Next, the operation of this embodiment will be explained. Infrared cameras 4-1 to 4-4 provided on each floor capture images within a predetermined range in front of the elevator entrance and send infrared image information corresponding to the number of people within the range to the elevator control device 3. . The CPU 31 of the control device 3 sequentially sends infrared image information from the infrared cameras 4-1 to 4-4 to the image processing section 33 in a predetermined cycle via the interface 32. The image processing unit 33 analyzes the number of people waiting on the floor, that is, the number of passengers, from the input infrared image information, and notifies the CPtJ 31 of the result. This allows the CPU 31 to know in advance the number of passengers waiting on each of the 1st to 4th floors.

Passengers waiting on each floor also press elevator movement request buttons 31 to 4 located on the front side of the elevator entrance. When this button is pressed on the 1st floor and 4PJ, the CPU 31 indicates that passengers on the 1st floor wish to go to the upper floor.
Passengers on the 14th floor can understand that they want to go to the floor below.

2. There are two elevator movement request buttons on the third floor, one to press when you want to live on the upper floor and one to press when you want to live on the lower floor, so only one button is pressed. If the passenger waiting on the 2nd or 3rd floor wants to live on the upper or lower floor, the CPtj31 can tell whether the passenger wants to live on the upper or lower floor, but if both buttons are pressed, the CPtj31 The number of waiting passengers is divided into a predetermined ratio of those who want to go up and those who want to go down.

Next, when the CPU 31 grasps the number of passengers waiting at 1 to 4 tW who want to go to the upper floor and the number of passengers who want to go to the lower floor, it refers to the elevator operation table stored in the memory 34. , Ill, and 2 are independently determined, and a corresponding control signal is output to the elevator drive unit 36 via the interface 35.

For example, in the example shown in FIG. 1, the CPLT 31 uses the image information of the infrared cameras 4-1 to 4-4 and the elevator movement request buttons 5-1 to 3-4 to perform the 1.2
．． 3. There are 0, 3, 2, and 1 passengers waiting on each of the 4 floors, and in this example, all the passengers want to move from each floor to the floor below. You can know.

Here, the elevator operation table stored in the memory 34 has data on the number of floors traveled by the elevator 1 and the travel course, corresponding to the number of passengers who want to go to the upper floor of each floor and the number of passengers who want to go to the lower floor. This data instructs the operating method of the elevator 1.2 in order to most efficiently pick up passengers waiting on the 1st to 4th floors and transport them to the desired floor. Therefore, from the table in the memory 34, the CPU 31 provides an elevator movement control signal to the elevator drive section 36 via the interface 35, as described below for the example shown in this figure. That is, first, the elevators 1 and 2 are driven at the same time to move the elevator 2 to the 4th floor and the elevator 1 is moved to the fourth floor.
move to the second floor.

Elevator 2 picks up one passenger on the 4th floor and descends to the 3rd floor.
It picks up two passengers on the floor, passes through the second floor and descends to the first floor. On the other hand, elevator 1 is 2 PIl and carries 3 passengers.
Descend to the floor. As a result, passengers on each floor shown in the figure are most efficiently transported to the first floor.

According to this embodiment, the elevator control device 3 can know in advance the number of passengers waiting on each floor who want to go to the upper floor and the number of people who want to go to the lower floor, and the elevator control device 3 can control the elevator in accordance with the number of passengers. Since the number of floors and course of movement of 1.2 can be controlled, the elevator 1.2 can be operated most efficiently, and the waiting time of passengers waiting on each floor can be shortened on any floor. , passengers can be quickly transported to the desired floor.

Note that the camera for determining the number of passengers on each floor is not limited to an infrared camera, and any camera that can determine the number of passengers may be used.

〔Effect of the invention〕

As described above, according to the elevator control device of the present invention, the number of passengers waiting on each floor is determined in advance, and the number of floors to which the elevator is moved is determined based on the result, thereby making it possible to operate the elevator efficiently. .
