Description

[Detailed Description of the Invention] This invention relates to an improvement of a display device provided in an elevator landing.

When some type of display is installed at an elevator landing, it is usually installed separately from the landing button. This is because the hall button is for registering a hall call, and the display is for displaying information to passengers waiting at the hall, and they have different functions.

However, installing these separately is subject to space constraints and is disadvantageous in terms of cost.

This idea improves the above-mentioned problem by displaying general information on the display, and when a waiting passenger is detected, the shape of a landing button is displayed on the display, and when the waiting passenger touches the shape of the landing button, To provide an elevator hall display device which can function as both a hall button and a display by registering hall calls.

An embodiment of this invention will be described below with reference to FIGS. 1 to 5.

In Figures 1 to 3, 1 is the wall of the elevator hall,
2 is a waiting passenger detector installed on the wall 1 of the hall and detects when a waiting passenger 3 approaches a predetermined distance by emitting ultrasonic waves or the like and receiving the reflected waves; 4 is below the waiting passenger detector 2; A thin display body 5 is installed on the wall 1 of the landing hall and is capable of displaying characters, figures, etc., and 5 is connected to the display body 4 and is buried in the wall 1 of the hall and commands the display body 4 to display according to input. A display device 6 is composed of a display body 4 and a display drive device 5. 7 is located behind the display 4 and is a wall 1 of the landing area.
This is a hall call detector for detecting that a waiting passenger 3 has touched the display body 4 buried inside the hall, and consists of an up call detector 7A placed at the top and a down call detector 7B placed at the bottom. 8 is a service floor disconnect switch installed in the manager's room, and 9 is a control device consisting of a microcomputer and installed in the elevator machine room, which is a central processing unit (hereinafter referred to as CPU).
9A, a storage device 9B consisting of a read-only memory (hereinafter referred to as ROM) in which programs and fixed value data are stored, and a readable/writeable memory (hereinafter referred to as RAM) in which data such as calculation results is temporarily stored;
It has an input device 9C connected to the up and down call detectors 7A, 7B, the waiting customer detector 2 and the service floor disconnect switch 8 to convert the signal level, and an output device 9D also connected to the display drive device 5. . 10 is a general information display means for emitting a signal to display general information from the output of the waiting passenger detector 2; 11 is a hall button display means for emitting a signal for displaying the figure of the hall button; 12 is the output of the hall call detector 7. Hall call registration means for registering a hall call from
Reference numeral 3 denotes a hall call display means for issuing a signal indicating hall call registration based on the output of the hall call registration means 12. Each of the display means 10, 11, and 13 described above is a known one as shown in, for example, Japanese Unexamined Patent Publication No. 55-40127.

Next, the operation of this embodiment will be explained using the flowchart of the program operation shown in FIG. 4 and the display contents diagram shown in FIG. 5.

In step 11, it is determined whether the corresponding landing is valid or not by inputting the open or close signal of the service floor disconnect switch 8 to the CPU 9A via the input device 9C. If the switch 8 is open, it is determined that the hall is valid, and in step 12 it is determined based on the output of the waiting passenger detector 2 whether or not the waiting passenger 3 is detected. If the waiting customer detector 2 does not emit an output, in step 13 the output device 9D and the display drive device 5
5A, predetermined general information (stored in the storage device 9B) is displayed on the display 4 as shown in FIG. 5a. Since the waiting passenger detector 2 is designed to emit a detection signal when it approaches the display 4 by a predetermined distance, the above general information can be obtained without erroneously detecting people passing through the hall, and by detecting these people and the hall caller. It can be seen by waiting customers who are heading toward the display 4 to register the information.

Next, when the waiting customer detector 2 detects the waiting customer 3 and outputs an output, in step 14, the display 4
Display the shape of the landing button. In step 15, whether or not the hall call has been registered is determined based on whether or not the waiting customer 3 touches the above-mentioned graphic. If the figure is not touched, the process returns to step 14 and the figure display is continued. When the finger of the waiting customer 3 touches the above-mentioned figure, for example the figure of the up button, the up call detector 7A is activated (when the finger of the waiting customer 3 touches the figure of the down button, the down call detector 7B is activated), and this signal is sent to the input device. 9C, and the uplink call is registered. When the up call is registered, in step 16, the entire shape of the up button displayed on the display 4 as shown in FIG. 5C is colored, indicating that the up call has been registered. The elevator car is then operated by a well-known control circuit (not shown), the car travels towards this floor, and when the car arrives, the up call is canceled. In step 17, it is determined whether or not the hall call has been canceled, and until the hall call is canceled, the process returns to step 16 and the coloring of the up button continues. When the up call is canceled, the color development is stopped in step 18, and the process returns to the figure shown in FIG. 5b. When the waiting customer 3 gets into the car and the waiting customer detector 2 stops emitting output, the process proceeds from step 12 to step 13, and the display 4 again shows the fifth signal.
General information is displayed as shown in Figure a.

Furthermore, after the figure on the hall button is colored, general information is displayed after a predetermined period of time has elapsed, and when a further predetermined time has elapsed, the figure on the hall button is displayed in color, and this can be repeated alternately until the hall call is canceled. You can do it like this.

In addition, if a forecast light (not shown) is installed separately to display the car that will respond to the hall call on this floor, if the car that should respond is already displayed, the shape of the hall button will not necessarily be displayed in color. There is no need to continue. Therefore, once the color display has been performed, the general information may be continuously displayed.

Next, if the service at this landing is to be cut off (to prevent cars from stopping at this landing), the switch 8 is closed. Now, in step 11, the landing is determined to be invalid, and in step 19, as shown in Figure 5d,
Predetermined information, such as "Kononori Baha Service Shimasen" and the fact that the corresponding boarding point is invalid are displayed. This display allows waiting passengers to know that this floor is out of service, so they can head to another boarding area.

As explained above, in this invention, when the waiting passenger detector at the hall does not detect a waiting passenger, general information is displayed on the display, and when a waiting passenger is detected, the shape of the hall button is displayed on the display. When a waiting passenger touches the shape of this hall button, a hall call will be registered.
Moreover, since this is displayed, the hall button and the information display are integrated into one, and there is no space restriction, and the structure can be constructed at a relatively low cost.
