Description

Description: TECHNICAL FIELD The present invention relates to a display control device for displaying information such as a weather forecast and entertainment guide on a display provided in an elevator car or a landing, for example. Is.

[Conventional technology]

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. This wasted time is used for various information (for example, weather forecast, news, advertisement, entertainment guide, conference guide, etc.)
In order to make effective use of the information, it has been proposed to provide a display device in an elevator hall or a car, and display the above information in characters or figures therein. Further, like the one described in Japanese Utility Model Laid-Open No. 60-100379, 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 so that the passenger can use the elevator efficiently. Some of the above are also proposed.

Further, a simple display device capable of displaying only ten or more characters at the same time and displaying the time and other guide information while scrolling is also put into practical use.

By the way, since various information such as the weather forecast, news, advertisements, etc. as described above have no value in the old days, the building manager needs to update the content of the information to be displayed as appropriate. Also, depending on the content, there is information that should be displayed at a fixed time. When displaying the predetermined information in such a predetermined time zone, it takes a lot of time if the administrator inputs the predetermined information into the display device each time, so that the time zone to be displayed in advance It is a general method to register the display contents using a reservation device.

[Problems to be solved by the invention]

However, when the number of separately reserved information increases, it may occur that a plurality of information must be displayed simultaneously in the same time zone. Conventionally, in such a case, one piece of information to be displayed is selected and displayed according to a predetermined priority order.
However, there is a problem in that the information required by users cannot be provided sufficiently.

The present invention has been made in order to solve the above problems, and information required by a user even when a plurality of separately reserved information must be displayed in the same time zone. It is an object of the present invention to obtain a control device of a display device that can display all of the above on a display device.

[Means for solving problems]

The display control device according to the present invention includes a clock for outputting time information, a display capable of simultaneously displaying predetermined information whose number of characters to be displayed is a specified value or less, and information for displaying on the display and the information. Storage means for respectively storing the periods, and a selection means for comparing the time information output by the timepiece with the display period stored in the storage means and selecting corresponding information according to the comparison result. A combination means for displaying the selected information on the display device, and when the selected information is plural, synthesizing means for connecting the plural pieces of information in a predetermined order and storing them as display information. And display information displayed by the combining means on the display.

[Action]

When there are a plurality of pieces of display information reserved during the reserved time zone, the display control device according to the present invention synthesizes these pieces of display information by a predetermined method and provides them in the elevator car or in the hall. Scroll to the displayed display.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is an overall configuration diagram of a display control device according to an embodiment of the present invention. In Fig. 1, (1) is an elevator car installed in a five-story building, (1A) is installed in the car, and a well-known fluorescent display capable of displaying 16 characters at a time Display consisting of pipes, (21) to (25) are elevator halls on the 1st to 5th floors, (21A) is the same indicator as the display (1A) installed in the elevator hall on the 1st floor, (10)
Is a display control device of the elevator. The display control device (10) of this elevator has time information (hour,
Clock (11) that outputs minutes), storage means (12) that stores a plurality of information to be displayed on the displays (1A) and (21A) and a period (start time and end time) for displaying them And the information to be displayed by comparing the time information with the display period stored in the storage means (12).
When it is detected that the selection means (13) selected from 2) and the selected display information are plural, the selected display information is connected in order and stored as one display information, and this is stored in the car. Display (1A) and hall display on the first floor
It is composed of a synthesizing means (14) for outputting to (21A).

FIG. 2 is a system configuration diagram of the elevator display control device (10). In FIG. 2, the display control device (10) comprises a microcomputer, a CPU (31), a ROM (32), and an R.
AM (33), clock IC (34), input circuit (35), and output circuit
It consists of (36). (37) is a switch for adjusting the clock IC (34), (38) is a reservation device for reserving the content of information to be displayed (hereinafter referred to as a display message) and a display period, and (38a) is a display. The reservation number signal that represents the reservation number of the message, (38b) and (38c) are the display start time and the display period signal that represent the display end time, respectively, and (38d) is the coded display character string signal that represents the display message. is there. The signal (36a) output from the output circuit (36) is the indicator (1
A), and a coded display information signal representing a message to be displayed on the hall display (21A) on the first floor.

Next, the operation of the elevator display control device (10) will be described with reference to the flowchart of FIG. The operation by the flow chart is executed by the arithmetic program stored in the ROM (32).

In FIG. 3, when the power is first turned on, the step (40
Initial setting is performed in 0). This default step (40
At 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 default step (400) is completed, the steps (401) to (409)
The process of is repeatedly executed.

In the step (401), the setting signal is fetched from the adjustment switch (37) for a watch through the input circuit (35), and the watch IC (34)
To the specified time. At the next step (402), the display message M registered by the reservation device (38) is displayed.
(I) and the display periods S (I) and E (I) are input together with the reservation number I and set in the RAM (33) as shown in FIG. In this embodiment, the maximum number of display messages that can be reserved by the reservation device (38) is 10, and the maximum length of the displayed text per message is 16 characters. All reserved display messages and periods are reserved devices (3
Since the reservation number data I becomes "0" when it is sent from the display control device (10) to the display control device (10), this is detected at step (403) and the process proceeds to step (404). Until the reservation number data I becomes "0", the display message and the period are successively input in step (402) and set in the RAM (33).

In steps (404) to (408), the display (1A) and
The message to be displayed in (21A) is selected and combined. In step (404), first, the numerical variable i representing the reservation number is set to "1", and the character variable D representing the synthesized display message is set.
(Hereinafter, referred to as a composite display message) is initialized to a character string (= null string) of length "0". Step (4
In 05), it is determined whether or not it is a time zone in which the display message M (i) of the reservation number i is displayed. If the time t input from the clock IC (34) is within the display period, S (i) ≤t <E (i), so that the process proceeds from step (405) to step (406) where the composite display message D is displayed. The display message M (i) is linked to update the composite display message D. At this time, a character string ".DELTA. #. DELTA." (.DELTA. Represents a blank) is inserted before the display message M (i) so that the break of the sentence can be easily recognized. Then, in step (407), the variable i is incremented by "1" for the processing of the next reservation number i + 1. If the current time t is outside the display period (t <S (i) or t ≧ E (i)) at step (405), the process proceeds to step (407) without doing anything and the variable i is updated. . As described above, the maximum number of display messages that can be reserved is 10. Therefore, when the processes of steps (404) to (407) have been completed for all the reserved display messages, the reservation variable i becomes "11", and the step ( Proceed from 408) to the next step (409). As a result, for example, when t = 11: 00, “GOOD MORNIGN
G. ”(00:00 to 12:00),“ TODAY IS FINE. ”(06:00 to 1
Three messages of “5:00)” and “TEMP. = 20 ° C.” (10:00 to 14:00) are synthesized and the displayed message D is as shown in FIG.

In step (409), for example, the synthesized display message D as shown in FIG. 4 is coded so that it can be displayed on the display devices (1A) and (21A), and 200 mse for each code.
It is sent to the displays (1A) and (21A) via the output circuit (36) at intervals of c. In the display unit (1A) and (21A), the display control device (10)
For example, the composite display message D sent from
200mse from right side to left side of indicator (1A) as shown
Display by scrolling one character for each c.
Then, when all the composite display messages D have been sent, the process returns to step (401) and the same processing is repeated.

As described above, in this embodiment, when a plurality of display messages are reserved in the same time zone, these display messages are combined to be combined into one display message, which is scroll-displayed on the display unit. Therefore, it becomes possible to inform the elevator passengers of all the reserved display messages. Also, at this time 2
A message delimiter is inserted between the two display messages to make the messages easier to read.

In the above embodiment, a 16-character fluorescent display tube was used as the display, but the display is not limited to this. It is also possible to use a plasma display, a liquid crystal, a charactor using a LED, a graphic display, or a CRT.

Further, the displayed message is not limited to characters, but may be composed of figures and characters.

Furthermore, the method of synthesizing a plurality of messages is not limited to simply connecting in the order of reservation numbers as in the above embodiment. For example, several categories (advertisement, news, weather, etc.) can be set according to the content of the message, and the categories can be easily combined and connected in sequence. In addition to scroll display, various other methods are possible, and as a method of displaying a plurality of information, display messages combined by the display control means (10) can be displayed on the display devices (1A) and (21A). Various other methods are conceivable in addition to the method of coding and sequentially sending to the display.

〔The invention's effect〕

As described above, according to the present invention, when the reserved time comes, the display information registered in advance is selected and displayed on the display provided in the elevator car or the hall. When it is detected that a plurality of separately reserved information must be displayed in the same time zone, the combining means joins the plurality of information in a predetermined order to create new display information. Since the display information is configured to be scroll-displayed on the above display unit, multiple reserved display information items that must be displayed in the same time zone can be displayed on the display unit with the number of characters that can be displayed at the same time being less than the specified value. All the display information reserved can be displayed and notified to the customer without exception.
