Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an apparatus for displaying information to a car and passengers inside an elevator while the elevator is moving up and down.

[Technical background of the invention]

Generally, the information that an elevator user can know from the elevator side includes the car position, car call, and car traveling direction in the elevator car, and then the car position and the first floor hall call in the elevator hall.

An indication of car direction of travel is provided.

In addition, in addition to this, there are overcapacity and starters in the cage.

Information such as departure and control operation display may be added.

As this display method, a method in which the dial is illuminated using an LED, an incandescent lamp, or the like is often used.

In recent years, as equipment in elevators has become more sophisticated, displays in elevators are often required to be more sophisticated. For example, instead of displaying each floor with dots, characters are often directly displayed to indicate the car position using a 7-segment display or the like.

In addition, text display devices are used to display control operations due to occurrences of earthquakes, fires, etc. in order to provide support to passengers.

Many of these character display devices are used, and are capable of displaying 16 to 20 characters, and each character is represented by 16 segments or a 5x7 dot matrix. This display device is a fluorescent display tube or LED.

It consists of a liquid crystal display, and various messages are displayed according to commands from the elevator control device installed in the machine room of the building.

Here, an example of a configuration diagram of an elevator character display device is shown in the third example.
As shown in the figure.

This example shows a device in which a fluorescent display tube 1 is used to represent one character as a 5×7 dot matrix, resulting in a 20-character character display device. Data for various messages are formed in the elevator control device 2, and one character data is converted into a one-byte code and transmitted from the elevator control bag a2.

The display device 3 receives the character code at the data input section 4, and displays the characters on the fluorescent display tube 1 according to the control code transmitted at the same time.

Here, the character code represents the type of character using a code, and an ASCII code is usually used. for example,
The letter A is represented by 41H1 and the number 1 is represented by 31H.

In addition to the above, the display device 3 also includes a central processing unit 5 (hereinafter referred to as rcPUJ), a data storage section 6, and an output buffer section 7. Character code data is stored in the data storage section 6, and is read at regular intervals. The data is sent to the fluorescent display tube 1 through the output sofa section 7.

In this manner, characters are displayed on the fluorescent display tube 1.

Generally, there are three types of display methods using the display device 3.

One is horizontal scrolling, which is a method of displaying messages as if they were flowing horizontally by shifting the characters one by one to the right at regular intervals, as shown in FIG. 4(a).

Next, as shown in FIG. 4(b), there is a method of dividing a continuous message into two and displaying each message separately at regular intervals, that is, vertical scrolling.

Furthermore, there is a fixed mode in which messages are displayed in a static manner.

Conventionally, the display method used in elevator cars has often been horizontal scrolling, in which messages of about 40 characters are displayed in sequence.

In other words, since horizontal scrolling is a form in which characters flow synchronously, passengers can easily keep their eyes on the display device continuously.

In general, horizontal scrolling often shifts characters once every 200 m5, and vertical scrolling often switches messages once every ISEC.

[Problems with background technology]

However, with horizontal scrolling, it takes 200 m s II! to display one character! If the message has 40 characters, it will take 8 SEC to display all the characters.

Therefore, in order for passengers to know this message, at least F3
Must remain in the elevator car during SEC.

However, the average time required for an elevator to stop at the nearest floor due to a controlled operation, etc. is 3 SEC.
Passengers who were not paying attention to the display device had the disadvantage that they could get off the elevator car without noticing the message.

Furthermore, even during normal operation, passengers going from the 3rd to the 4th floor, for example, may get off the elevator car before finishing reading the message due to the short usage time, making it difficult for the display device to provide sufficient service. There were no drawbacks.

[Purpose of the invention]

The present invention is an elevator display device that overcomes the difficulties of conventional devices and makes it possible to notify all passengers of a message by changing the way the message is displayed in accordance with the operation of the elevator. Its purpose is to provide.

[Summary of the invention]

The present invention provides a data input section for inputting information from an elevator control device, a data storage section for storing data, a CPU for managing data exchange operations, and an output buffer section for outputting data. In a display device equipped with displays for displaying output data from an output buffer section, several types of character display methods are prepared in advance, and the time required to display a message is If you memorize the calculation and the display time is longer than the expected operating time of the elevator, you can change the display mode to another method to ensure that the message is displayed during one run. This is an elevator display device that makes it possible to

[Embodiments of the invention]

The circuit configuration of the present invention will be explained in the same case as the display device explained in FIG.

Therefore, the display section is equipped with a CPU, and consists of a 20-character fluorescent display tube and a human output buffer, the details of which are shown in FIG.

In FIG. 1, it is assumed that the display device 3 is installed in an elevator car, and the display portion is placed above the operation panel.

The fluorescent display tube 1 is a device capable of displaying 20 characters represented by 5×7 dots, and each dot is dynamically illuminated. That is, at any given time, only the seven dots in one row of a certain character are controlled, and the other dots are turned off. The display is time-divisionally turned on in units of 7 dots so that the next column is controlled in the next cycle.

Output buffer 1 part 7A that provides data to 7 dots in this column
and an output pan 77 that gives data to the dots in the time division row.
Section 7B is installed around the periphery.

Characters are created by a character generator 8 and time-shared controlled by a timing generator 9.

Time-sharing control of display is performed regularly regardless of the CPLI 5, but since the data to be displayed is stored in the data storage unit 6 shared with the CPU 5, the multiplexer 10 switches the address for controlling the data storage unit 6. It becomes the composition.

Further, the data code and control code sent from the Nirepeter control device are stored in the data storage section 6 by the input buffer section 4 under the control of the CPLI 5.

The display flowchart in one embodiment of the present invention is shown in the second example.
As shown in the figure.

FIG. 2 shows the operation of the display in the elevator car, and assumes that it is normally executed in horizontal scroll mode. The display device constantly displays elevator operation indicators such as full or suspended, and service indicators such as lunch information and first floor information, depending on the situation.

Steps 401 and 402 are routines for selecting data to be displayed, and display character data is created regardless of the operating mode.

In the conventional example, the display is directly performed after this, but in this embodiment, one operation time of the elevator is displayed in step 403.
It is calculated by.

This calculation predicts the time from the door open state to the door closing and the door opening again and the time required for one run.
If the latter is determined to be longer than the time required to complete the display in step 406, the mode is forcibly switched to the vertical scroll mode in step 406.

Conversely, if it is determined that the required display time is shorter, the horizontal scrolling state is continued in step 405.

The travel time required for this comparison can be determined from the floor height of the building and the speed of the elevator.

In this embodiment, the message is normally displayed in horizontal scroll mode, and when it is determined that an emergency is required, the process is switched to vertical scroll mode.

When the number of characters to be displayed is 40, the time required for display is approximately 8 SEC for horizontal scrolling and 2 SEC for vertical scrolling, and since the general elevator running time is at least 3 SEC, this requirement can be fully satisfied.

As mentioned above, according to this embodiment, not only is it possible to shorten the time it takes for all passengers to read the message, but also it is possible to focus the passengers' eyes on the display device by changing the display mode. This makes it possible to convey messages reliably.

In this embodiment, a case has been described in which the horizontal scroll mode is changed to the vertical scroll mode, but as another embodiment of the present invention, it is also possible to display the main points of a message in a fixed mode.

〔Effect of the invention〕

Thus, according to the present invention, when there is an urgent need for the elevator display device, the display mode can be changed to effectively convey the display message.

This has the following additional effects.

a) Changing the display mode can shorten the display time, giving passengers more time.

Since passengers do not overlook emergency messages, it is possible to prevent passengers from taking action without knowing that a situation such as an earthquake or fire has occurred, and resulting in a disaster.

b) By changing the display mode, a single display changes, which can attract the attention of passengers.

If the messages are simply flowing, there is an advantage that messages needed by passengers will not be overlooked.

(1) After the emergency is no longer present, the display returns to normal display mode and starts displaying from the first letter, making the display easy to understand for new passengers using the elevator.
