Abstract

PURPOSE:To prevent misunderstanding of the content by detecting the completion of the display of the final character of the significant characters when a new scroll speed is designated, and switching the scroll speed to a new value to facilitate the message to be seen. CONSTITUTION:When a new scroll speed is selected by a scroll speed selecting switch 38, the data of the new scroll speed data and the data of the lamp switching-off time are set by a new scroll speed number signal 38a. The display mode (scroll speed, blinking period, blinking ratio) is determined according to these data, the message data are coded, and outputted to display devices 1A and 21A as the display information signal through an output circuit 36 code by code successively. Then, a judgement is made whether or not all the significant character strings of the message data are outputted. After the completion of the display of the significant characters is detected, the scroll speed is switched to a new value for the first time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car or an indicator installed at a landing, for example, to provide elevator information such as a fire, an earthquake, a power failure, or the like, and information such as time and weather when the car is full. The present invention relates to switching of the display speed of an elevator that displays general information such as a forecast.

[0002]

2. Description of the Related Art The time when an elevator user waits for a car to arrive in the elevator hall or the time when he / she is in the car is essentially wasted time. In order to effectively use this wasted time for obtaining various kinds of information (for example, weather forecast, news, advertisement, entertainment guide, conference guide, etc.), a display device is installed in the elevator hall or the car. Change the above information into letters and figures (Hereafter, what is changed into these letters and figures is called "message".)
What to display is suggested.

Further, as disclosed in Japanese Utility Model Laid-Open No. 60-100379 and Japanese Patent Laid-Open No. 60-167871, a car position, a driving direction, a next stop floor, etc. are displayed on a display device based on elevator driving information. Elevator guidance devices have also been proposed that display and allow passengers to use the elevator efficiently. Further, a simple display device capable of displaying only ten or more characters at the same time and displaying time and other guide information while scrolling is also put into practical use.

This scroll display method has a problem that it is difficult to read because the characters move, but even if the message is composed of a character string longer than the number of characters that can be simultaneously displayed on the display device, all the contents can be displayed. There is an advantage that you can. Then, by operating a correction device such as a switch, the scroll speed, which is the moving speed of the message on the display, is changed to a desired speed.

[0005]

However, if the scroll speed is changed in the middle of displaying one message, the illusion that the message is switched to another message different from the previous one is given to the user, and It was feared that the contents of the message would be difficult to convey, giving the misunderstanding as if the contents of the message were lighter than the previous ones.

The present invention has been made in order to solve such a problem, and even if the scroll speed is changed by the correction device, the scroll-displayed message is easy to see, and the content thereof is misunderstood. It is an object of the present invention to obtain an elevator display speed switching device capable of switching the display speed of a message without fail.

[0007]

SUMMARY OF THE INVENTION An elevator display speed switching device according to the present invention is provided in a car of an elevator or at a landing, and the number of characters that can be simultaneously displayed is limited to a specified value or less. Storage means for respectively storing a plurality of information to be displayed on the container, selection means for creating a character string by selecting the information stored in the storage means when a predetermined condition is satisfied, and the character string When a new scroll speed is specified by the scroll speed changing means, the last character of the valid character A switching means is provided for detecting that the display has ended and switching to a new scroll speed.

[0008]

In the elevator display speed switching device according to the present invention, when the speed at which a predetermined message is scroll-displayed is changed by the scroll speed changing means,
After the switching means detects the display end of the last character of the message, the scroll speed is switched to a new scroll speed.

Therefore, the scroll speed when actually moving the message is expressed as the reciprocal of the scroll speed data S (1) to S (5). Similarly, F (1) to F (5) are extinguishing period data corresponding to the values (= 1 to 5) of the scroll speed number signal (38a). The extinguishing period during the blinking cycle of the message is "mse".
c ".

Next, an elevator display controller (10)
The operation will be described with reference to the flowchart of FIG.
The operation according to this flowchart is executed by the arithmetic program stored in the ROM (32). In FIG. 4, when power is first turned on, initialization is performed in step (500). This initialization step (50
In 0), the data in the RAM (33) is set to a predetermined value such as "0", and the clock IC (34) is reset.
When the initial setting step (500) is completed, the processing of the subsequent steps (501) to (513) is repeatedly executed.

In step (501), the input circuit (3
The setting signal is taken in from the adjustment switch (37) for the timepiece via 5) and the timepiece IC (34) is adjusted to the designated time. Further, the time (hour: minute) is input from the clock IC (34) and the time data T is set in the RAM (33).

In the next step (502), the message data D is "WELCOMEΔTOΔTHEΔHOTEL! Δ" +
T + “ΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔ” (Δ indicates a blank). Number of valid characters of message data D = “27”
(The last 16 blanks are the indicators (1A) and (21
This message is added for the sake of convenience so that the next message is displayed after the message is displayed on the screen of A) and disappears from the screen by scrolling, and is not included in the effective number of characters of the original message. ) To R
Set to AM (33).

Next, at step (503), the scroll speed number signal (38a) is inputted from the scroll speed selection switch (38), and it is used as the number data I in the RAM.
Set to (33) and scroll speed data S
(I) and the extinction period data F (I) are set in the RAM (33).

In the next steps (504) to (513), the display form (scroll speed, blinking cycle, blinking ratio) is changed according to the specified scroll speed data S (I) and light-off period data F (I). Then, the message data D is coded so that it can be displayed on the display devices (1A) and (21A), and the display data signals (36a) are sequentially displayed as the display information signals (36a) via the output circuit (36) one code at a time. Output to (21A).

First, in step (504), a variable N (R
It is set to AM (33). ) Is initialized to "1". In step (505), a variable M representing the number of output characters (set in the RAM (33)) is initialized to "0", and the cursors (display on the screen) of the display units (1A) and (21A) are displayed. Power position) is set to the left end.

Next, in step (506), the (N + M) th character from the beginning of the message data D is coded so that it can be displayed on the displays (1A) and (21A), and the output circuit (36) is set. Through indicators (1A) and (2
1A).

In step (507), the variable M is set to "1".
And the cursors on the indicators (1A) and (21A) are moved to the right by one character. In step (508), the Nth to (N +) th from the beginning of the message data D
It is determined whether all the M) th character string (16 characters) has been output. Then, until the output of all the character strings is completed, that is, until the variable M> 16, step (5
When the processing of 06 to 508 is repeated and the output is completed, the process proceeds to step 509. As a result, the indicator (1
In (A) and (21A), for example, "WELCOME ΔTO ΔTHE ΔH” is simultaneously displayed on the screen as shown in FIG. 5 (when the variable N = 1). Then, in step (509), the time (S
Wait for (I) -F (I)) and proceed to step (510).

At step (510), the screens of the display devices (1A) and (21A) are cleared, and then step (511).
Light-off period data F corresponding to the light-off period during the blinking cycle
Wait for the time of (I) and proceed to step (512). In step (512), the variable N is incremented by "1", and finally in step (513), it is determined whether or not all valid character strings (L characters from the beginning) of the message data D have been output. Then, until the output of all the character strings is completed, that is, until variable N> variable L, step (505).
The process of (513) is repeated, and when the output is completed, the process returns to step (501).

As a result, the indicators (1A) and (21
On the screen of A), one character is scrolled per time S (I) (msec), and this time S (I) (msec) is also scrolled.
During this period, the light is turned off once for F (I) (msec). Therefore, the blinking period is S (I) (msec), and the blinking ratio is {(S (I) -F (I)) / F (I)}. The message "WELCOME △ TO △ THE △ HOTEL! △ 1
1:05 ″ (when time data T = 11: 05) is scroll-displayed.

When all the messages have been scrolled, the process returns to step (501) and the same processing is repeated. At this time, if a new scroll speed has already been selected by the scroll speed selection switch (38), the new scroll speed data S (I) and the new scroll speed data S (I) are sent by the corresponding new scroll speed number signal (38a) in step (503). Light-off time data F
(I) is set, and the processes of steps (504) to (513) are performed.

That is, the scroll speed selection switch (3
Even if 8) is operated, the scroll speed is not immediately changed, but the scroll speed is changed to a new scroll speed only after it is detected in step (513) that the display of the number of valid characters is completed. Therefore, step (5
13) is a switching means (6) for switching the scroll speed.
It functions as a).

As described above, in this embodiment, when the scroll speed selection switch (38) is used to change the message scroll speed in the car and the hall indicators (1A) and (21A), the scroll speed is switched. Does not occur while the effective characters of the message are being displayed, but is separated by the message, so it does not give any illusion or misunderstanding to the user, and it is possible to switch to another message by switching the scroll speed. It can be easily recognized by the customer, and the content of the message can be easily communicated.

Example 2. Example 1 above. So, since we used a one-line display, the scroll direction is "left to right".
However, the scroll direction is not limited to this. If it is a display device capable of displaying a plurality of lines, it is easy to set the scroll direction to “from bottom to top”, for example.

Example 3. Example 1 above. Then, a fluorescent display tube capable of displaying up to 16 characters at the same time was used as a display, but the display is not limited to this. It is easy to apply the present invention regardless of whether the display is capable of displaying 8 characters or 40 at the same time. Further, a fluorescent display plasma display, a liquid crystal display, a character or graphic display using an LED, or a CRT may be used as the display.

Example 4. Example 1 above. In the above, the types of display characters that can be used in the message are alphabets, numbers, and symbols, but the types of display characters are not limited to these, and kanji or kana characters may be used. Furthermore, if a figure can be treated in the same way as a character, it can be treated as a special character.

[0030]

Industrial Applicability As described above, according to the present invention, an indicator provided in the car of the elevator or in the hall, and at the same time, the number of characters that can be displayed is limited to the specified value or less. Storage means for storing a plurality of character information respectively, selection means for selecting the information stored in the storage means to create a character string when a predetermined condition is satisfied, and converting the character string into a character code. Then, in the one provided with an output means adapted to move the display at a specified speed to scroll display, when a new scroll speed is specified by the scroll speed changing means, the last character of the effective character string is Detecting the end of the display, the switching means to switch to the new scroll speed is provided, so the scroll speed is switched at the message delimiter The transition to the message can be easily recognized.

As a result, the harmful effect of switching the scroll speed in the middle of one message, that is, the illusion of switching to another message, or the content of the message becomes lighter than that of the previous message. There is no misunderstanding, and the contents of the message are easily transmitted.
