Abstract

PURPOSE:To perform not only usual display but also guiding display having various screen formats by performing man-machine processing in a main control part so that an optional display pattern can be selected. CONSTITUTION:A man-machine controller 1 can select and operate a still character data display, a scroll character display and a graphic display, etc. At the time of displaying the still character, an instruction for altering a screen is given from the input part 2 of the controller 1 and the data such as destination, time and invitation document, etc., is searched according to external data or an internal signal from the input part 2. Then, displayed character, color and position, etc., are encoded and transmitted to a screen controller 4, where display processing is started. At the time of horizontally scrolling the character from right to left, addresses on a video memory 8 corresponding to the upper left position of a display screen are shifted fro a small one to a large one so as to obtain the scroll display. At the time of performing the graphics display, a font memory 6 where graphic pattern is stored is accessed and then dot pattern, color and attribute are written in the video memory 8.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a guide display device that can be used as a public information board, for example, inside a station or at an airport (prior art). Solar, flap, and subtitle type devices are conventionally used as guidance display devices for displaying timetables and flight information at airports and airports. These devices have a structure that includes the necessary number of display surfaces on which display patterns are written in advance, and mechanically accesses the display surfaces to be displayed one by one according to the display schedule, and sets the corresponding display surface to the display position of the display device. By setting this, information on timetables, flights, etc. can be displayed to passengers.

Additionally, there is a magnetic type of large guide display device that displays graphics. This screen is constructed by arranging spherical pixels painted in two colors on the display surface and non-display surface, and the screen is switched by rotating 1800 pixels using magnetic force.

(Problem to be Solved by the Invention) However, in such conventional solar, flap, and subtitle type guidance display devices that display timetables and flight information, the display device itself is structurally provided with multiple display patterns. Because of this, there is a structural limit to the number of patterns that can be displayed, and if it becomes necessary to display a new pattern, a new display surface with that pattern written on it must be created and attached to the device. First, various displays cannot be easily performed, and since the display device is fixed, a wide variety of displays cannot be performed, which limits the use of the display.

In addition, even with conventional magnetic guide display devices that display graphics, it is impossible to display a variety of displays due to limitations in display patterns.In order to display new patterns, it is necessary to configure the screen. The problem is that new pixels must be created and replaced by the same number of pixels, which is time-consuming, and the range of information that can be provided to customers is naturally limited.

This invention was made in view of these conventional problems, and allows a single device to display various screens such as schedules such as timetables and flight information, information displays, and graphics without being subject to structural limitations. The purpose is to provide a guide display device that can display information.

[Structure of the Invention] (Means for Solving Problem i) The guide display device of the present invention includes an input section for inputting display content instruction data, and a screen format and display content determined by input data from the input section. , a main control section that outputs a display control code, a font memory that stores dot patterns of characters, graphics, etc., and a display dot pattern that receives code signals from the main control section and refers to the font memory. , a sub-control section that controls the screen, and a display section that receives an output signal from the sub-control section and blinks LEDs arranged in a dot shape.

(Function) In the guide display device of the present invention, an external signal is inputted to update the display through the input section, and a display data table is preset in the main control section based on input data from the input section and instructions from an internal timetable, etc. and outputs the display contents to the sub-control unit as a code signal.

The sub-control section receives the transmission data from the main control section, calls up character fonts, graphic fonts, etc. corresponding to the display elements from the font memory, creates a display dot pattern, and uses this to create a dot pattern on the display section. A guide is displayed by blinking the LEDs arranged in a row.

(Example) Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows an embodiment of the guide display device of the present invention, in which a man-machine control device 1 serving as a main control section includes an input section 2 for receiving and taking external signals for updating the display, and an input section 2 for receiving and taking external signals for updating the display. The control unit 3 searches a preset display data table using input data and an internal timer, and transmits display contents in the form of a code.

4 is a screen control device serving as a sub-control unit, which includes a CPU 5 that receives data transmitted from the control unit 3 and performs display control, a font memory 6 that stores dot patterns such as characters and graphics, and a screen that performs screen control. It is composed of a controller 7, a video memory 8 in which display data is written, and a display section 9 composed of an ED module in which a large number of LEDs are arranged in a matrix in both directions.

The operation of the guide display device having the above configuration will be described next.

The man-machine control device 1 is equipped with a function for operating and selecting static character data display, scrolling character display, a mixed display thereof, and a graphic display as a man-machine function.
Man-machine processing is performed according to the flowchart shown in FIG.

First, a basic display schedule is read when the system is started up (step 81).

Next, based on this display schedule, the display data table is searched using trigger signals such as external signals and internal timers, and the screen is sequentially updated by outputting the destination, time, and guide code (step 82-35
).

It is possible for the man-machine to select irregular display processing other than this normal display, and when an operation selection signal is input from the outside (step S6), each display processing is started according to the selected content. (Steps S7a-S
7").

The layout function in step S7a displays a layout different from the normal pattern by changing the static character display position and the scroll character display position.

The graphic creation function in step S7e creates a graphic pattern by man-machine processing and writes the pattern data into the memory 6 of the screen control device 4 via the man-machine control device 1.

The graphic display function in step S7d performs graphic display by sending the graphic pattern code to be displayed from the man-machine control device 1 to the screen control device 4.

The guide text creation function in step S7c is for creating a new guide text and updating the guide text table.
The guide text display function 7b is for selecting and displaying an arbitrary guide text from the guide text table.

The schedule correction function in step 87f corresponds to temporary timetables other than the basic schedule, and creates a schedule table to be displayed on the current day by merging the basic table and the correction table.

Therefore, when displaying static characters, a screen update command is given from the input section 2 of the man-machine control bag W11 according to the flowchart shown in FIG. 3 (step 511), and external data input from the input section 2 is , or by a signal from an internal timer, etc., the data to be displayed, such as destination 1 time and guidance text, is searched from the timetable data table, flight schedule data table, and guidance text table (step 512), display text 1 color 2 position 1 inversion, etc. Code the display attributes such as flicker and send it to the screen control bag gi4 (
Steps 813, 814).

Accordingly, in accordance with the flowchart shown in FIG. 4, the screen control device 4 enters display processing upon receiving display data from the man-machine control bag w11 (step 521).

In this display process, first, one display character is read from the received text, the font memory 6 is accessed according to the character code, and the corresponding character dot pattern is read out (steps S22, 523). The transmitted color and attribute code are also written into the video memory 8 corresponding to the position code, which is also the transmitted data (steps 824 and 825).

When the processing of one character is completed, the process moves on to the next character, and this process is repeated until the dot patterns and attribute codes of all received characters are written into the video memory 8 (steps 822 to 525).

When writing of all characters is completed, display of a new screen is started (step 826).

Next, the operation when displaying scroll characters will be explained using FIG. Now, if characters are to be scrolled horizontally from right to left, the address on the video memory 8 corresponding to the upper left position of the display screen 10a is called the base address, and this base address is By sequentially shifting from the top to the top, the display data appears to flow from right to left on the screens 10a, 10b, . . . 1, and a scroll display can be obtained.

FIG. 6 is a flowchart of the scrolling process of the screen control bag M4, in which external signals inputted at a constant period are counted to generate a scroll time (step 531).

Then, when it is time to scroll (step 832), the base address of the video memory 8 is shifted in the scrolling direction by the required number of dots (step 533), and a new state is displayed (step 534).

By repeating this process, a scroll display in which characters flow at a constant speed can be obtained.

Furthermore, it is also possible to display a still screen and scrolling characters on the same screen, but in order to do so, the screen control device 4 first identifies the static character data and the scrolling character data from the received data, and displays each video in accordance with the position data. Write the display pattern to memory 8.

In other words, in the area corresponding to the still screen of the video memory 8, blanks are written in the parts that overlap with the display position of scroll characters, and in the area corresponding to the scroll screen, blanks are written in the parts that overlap with the static characters, thereby enabling man-machine control. It is possible to create and display a screen with a mixture of static characters and scrolling characters in a layout according to the position data sent from the device 1.

FIG. 7 shows a flowchart of the graphic display processing of the screen control device 4. The graphic pattern is stored in advance in the memory 6 of the screen controller @4. Then, upon receiving the graphic pattern code sent from the man-machine control device 1 (step S41.84.
2) Access the memory 6 that stores the graphic pattern, read the dot pattern, color, and attributes (step 543), and write the dot pattern, color, and attributes to the video memory 8 corresponding to the display position to create an arbitrary dot unit. (step 844)
, 845).

The display unit 9, which has LED modules arranged in series, can be made stationary by turning on or off the corresponding LEDs in response to the dot signal created by the screen control device @4 and the vertical and horizontal synchronization signals. Characters, scroll characters, and graphic displays are displayed on one screen according to a display pattern created by the screen control device 4.

In this way, by selecting and inputting on the man-machine control device 1, various formats can be used, such as not only schedule change statements, but also static characters, scrolling characters, layout changes by specifying display positions, graphic displays, etc. Necessary information can be displayed on the display section 9 and provided to customers in a timely manner.

[Effect of the invention 1 As described above, according to the present invention, by selecting an arbitrary display pattern through man-machine processing in the main control unit, it is possible to display change schedules, guide texts, advertising texts, graphics, etc. in addition to the normal display. It is possible to display guidance in a variety of screen formats simply by inputting information from the main control unit.

In addition, the display section does not have the display pattern itself; instead, the necessary display dot patterns are called from the font memory and combined to create display patterns for characters, sentences, graphics, etc., unlike conventional displays. No work is required to attach the display unit to change the display pattern, and display patterns can be easily changed or added using only man-machine processing.

Furthermore, since the LEDs are arranged in a dot shape on the display,
It has the advantage that the display is easy to see, and eye-catching displays such as color inversion and flicker can be easily performed.
