Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an indicator installed in a car of an elevator or at a landing, for example, guidance in an emergency such as fire, earthquake, power failure, etc., or when the car is full. The present invention relates to an elevator display device for displaying general information such as elevator information, time, and weather forecast.

[Prior 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 a car is essentially wasted time. In order to effectively use this wasted time for obtaining various kinds of information (for example, weather forecast, news, announcement, entertainment guide, conference guide, etc.), a display device is installed in the elevator hall or the car. Has been proposed in which the above information is converted into characters or figures (hereinafter, the characters or figures are converted into "messages") and displayed. Further, as disclosed in Japanese Utility Model Laid-Open No. 60-100379 and Japanese Patent Laid-Open No. 60-167871, the car position, the driving direction, the next stop floor, etc. are displayed on the display device based on the driving information of the elevator, Elevator guidance devices have also been proposed that allow users to use elevators efficiently. Further, a simple display device capable of displaying only ten or more characters at the same time and displaying time and other guidance information while scrolling is also put into practical use.

This scroll display method has a problem in that it is difficult to read because the characters move, but it is possible to display the entire contents of a message consisting of a character string longer than the number of characters that can be simultaneously displayed on the display device. There are advantages. 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.

[Problems to be Solved by the Invention] However, when all or part of a character string to be displayed to attract the attention of a user is displayed while blinking, if the speed of scroll display is changed as described above, There is a problem that the blinking period and blinking ratio do not match the scrolling speed, which makes it difficult to read the message.

In particular, when the display device displays one character at a time, the character string is scrolled for each character. Therefore, it is easy to see whether the blinking cycle or blinking ratio matches the scroll speed. Will have a great impact on.

The present invention has been made to solve the above problems, and provides an elevator display device in which a blinking message can be easily seen even when the scroll speed is changed by a correction device. With the goal.

[Means for Solving the Problem] An elevator display device according to the present invention is provided in a car of an elevator or in a landing, and a display device in which the number of characters that can be displayed at the same time is limited to a specified value or less. Storage means for respectively storing a plurality of information to be displayed,

Message output means (15) for outputting a message to the in-car display (1A) and the first floor hall display (21A) to display the message to be displayed in a predetermined display form It is configured.

FIG. 2 is a system configuration diagram of the display control device (10). In FIG. 2, the display control device (10) is composed of a microcomputer, and includes a CPU (31), ROM (32), RAM (3
3), clock IC (34), input circuit (35), and output circuit (3
It consists of 6). (37) is a switch for adjusting the clock IC (34). The signal (36a) output from the output circuit (36) is a coded display information signal representing a message to be displayed on the in-car display (1A) and the first floor hall display (21A). (38) is a scroll speed selection switch corresponding to the scroll speed changing means (6) in FIG. 1, and (38a) is this scroll selection switch (3).
With the scroll speed number signal selected in 8), the value (= 1 to 5) corresponding to the scroll speed is output.

FIG. 3 shows data stored in the ROM (32) of the display control device (10), and S (1) to S (5) are values (= 1 to 1) of the scroll speed number signal (38a). The scroll speed data corresponds to 5). Here, the time required to scroll the message by one character (the unit of time is millisecond (hereinafter referred to as "msec")). } Is shown. Therefore, the scroll speed when actually moving the message is the scroll speed data S (1)-
It is expressed as the reciprocal of S (5). Similarly, F (1) to F (5) are values (= 1 to 1) of the scroll speed number signal (38a).
In the light-off period data corresponding to 5), the light-off period during the blinking cycle of the message is represented by "msec".

Next, the operation of the elevator display control device (10)
A description will be given according to the flowchart in the figure. The operation according to this flowchart is executed by the arithmetic program stored in the ROM (32).

In FIG. 4, when the power is turned on, the step (50
Initial setting is performed in 0). This initialization step (5
In 00), 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 subsequent steps (50
Repeat steps 1) to (513).

In step (501), the setting signal is fetched from the timepiece adjustment switch (37) through the input circuit (35), and the timepiece IC is read.
Adjust (34) to the specified 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), message data D = "WEL
COME △ TO △ THE △ HOTEL! △ ”＋ T ＋“ △△△△△△△△
"△△△△△△△△" (△ represents a blank) and the number of effective characters L of the message data D = "27" (the last 16 blanks are the screens of the display (1A) and (21A). Is added for convenience to configure to start displaying the next message after a message is displayed on the screen and then disappears from the screen by scrolling, and is not included in the effective number of characters of the original message.) RAM ( 33).

Next, in step (503), the scroll speed number signal (38a) is input from the scroll speed setting switch (38) and set as the number data I in the RAM (33), and the scroll speed data S (I) and The OFF period data F (I) is set in the RAM (33).

In the following steps (504) to (513), the specified scroll speed data S (I) and the extinguishing period data F are specified.
Display form (scroll speed, blinking period,
The blinking ratio) is determined and the message data D is displayed (1
A) and (21A) are coded so that they can be displayed, and the display information signal (36
Output as a) to the indicators (1A) and (21A).

First, in step (504), a variable N (set in the RAM (33)) representing the position of a character to be output in the message data D is initialized to "1". Step (505)
Then, the variable M representing the number of output characters (set in the RAM (33)) is initialized to "0", and the cursors (indicating the position to be displayed on the screen on the display (1A) and (21A) are displayed. .) To the left end.

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

In step (507), the variable M is incremented by "1" and the cursors on the indicators (1A) and (21A) are moved to the right by one character. In step (508), it is determined whether all the Nth to (N + M) th character strings (16 characters) from the beginning of the message data D have been output. Then, until all the above character strings are output, that is, the variable M> 16
The processes of steps (506) to (508) are repeated until the above condition is reached, and when the output is completed, the process proceeds to step (509). As a result, the indicators (1A) and (21A) display “WELCOMEΔTO” as shown in FIG. 5 (when the variable N = 1), for example.
ΔTHEΔH "will be simultaneously displayed on the screen. Then, in step (509), wait for a time (S (I) -F (I)) corresponding to the lighting period in the blinking cycle, and then proceed to step (51).
Go to 0). In step (510), the indicators (1A) and (21
The screen of A) is cleared, and in step (511), the process waits for the time of the corresponding period data F (I) corresponding to the extinguishing period in the blinking cycle, and the process proceeds 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, the processes of steps (505) to (513) are repeated until the output of all the character strings is completed, that is, until the variable N> the variable L is satisfied,
When the output is completed, the process returns to step (501).

As a result, on the screens of the indicators (1A) and (21A),
Scroll one character per time S (I) (msec), and F (I) (msec) during this time S (I) (msec)
Turn off only once. Therefore, the blinking period is S (I) (mse
c), and the blinking ratio is {(S (I) -F (I)) / F
(I)}. The message "WELCOM
E △ TO △ THE △ HOTEL! △ 11: 05 "(when time data T = 11: 05) is scrolled.

Then, when all the messages have been scrolled, the process returns to step (501) and the same process is repeated. At this time, if a new scroll speed is selected by the scroll speed selection switch (38),
The new scroll speed data S is generated by the new scroll speed number signal (38a) corresponding to the step (503).
(I) and the extinguishing period data F (I) are set, and then the processes of steps (504) to (513) are performed.

As described above, in this embodiment, when the scroll speed selection switch (38) is used to change the scroll speed of the messages in the car and the hall indicators (1A) and (21A), the scroll speed is changed according to the specified scroll speed. The blinking mode (blinking period, blinking ratio, etc.) of the blinking display is also changed so that the message can be easily seen even when the scroll display and the blinking display are used.

In the above-described embodiment, since the single line display is used, the scroll direction is “left to right”, but 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.

Further, in the above embodiment, the blinking cycle is set equal to the scroll speed data S (1) to S (5). This is because the method of scrolling characters is one character at a time, and it is difficult to see if the blinking cycle differs from the scroll speed data S (1) to S (5). If there is a method of scrolling by the minimum unit (dot) that constitutes the screen, such a problem does not occur, so it is not necessary to set the scroll speed data S (1) to S (5) and the blinking cycle to be equal. The scroll speed data S (1) to S
Corresponding to (5), the blinking cycle data is used as the extinction period data
It may be set in the ROM (32) as in (I).

Furthermore, in the above embodiment, the blinking period and the extinguishing period are used as the blinking parameters, but the ones used as the blinking parameters are not limited to these. A combination of the blinking period and the lighting period, only the blinking period, or only the blinking ratio may be used as a parameter.

Furthermore, in the above-described embodiment, the display (lighting) and the turning off of the character portion are alternately performed as the blinking display, but instead of turning off the entire character, black and white inverted characters (for example, turning off the character portion and turning on the background portion It goes without saying that the present invention can be applied as it is to the case of using the lit one) and blinking the display.

Furthermore, in the above embodiment, the fluorescent display tube capable of displaying up to 16 characters at the same time was used as the 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 at the same time or 40.

Furthermore, as a display, a plasma display or liquid crystal,
A character or graphic display using LEDs or the like, or a CRT may be used.

Furthermore, in the above embodiment, the types of display characters that can be used in the message are not limited to this, and may be Chinese characters or Kana characters. Furthermore, if a figure can be handled in the same way as a character, it may be treated as a special character.

[Effects of the Invention] As described above, according to the present invention, an indicator provided in a car of an elevator or in a landing and the number of characters that can be simultaneously displayed is limited to a specified value or less. Storage means for storing a plurality of character information of each, a 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. A scroll speed changing means in which the display device is moved at a specified speed for scroll display and at the same time all or part of the character string is blinked according to a parameter for determining the display form. The above-mentioned scroll speed is changed by, and the above-mentioned parameter is also changed in accordance with the scroll speed specified by the blinking parameter setting means. With this configuration, it is possible to easily see the blinking message even when the scroll speed is changed.
