1 shows a system configuration diagram of the present invention.

Here, the host computer 1A, which is the central control unit 1, constitutes a local area 21-2n connected to the host computer 1A by means of a communication network 11-1n, 3 including a communication line or an optical cable. It consists of the host computer 1A of the central control part 1 which controls and manages.

The area 21-2n analyzes the commands and information of the central control unit 1 to drive the general guide indicator (8 ^l -8 ^m ) and the guide indicator (9 ^l -9 ^L ) to guide the user. The central control unit 1 manages only the violent and takes care of other tasks as well as displaying information.

The local control section 5 of the local section 2 performs the command of the central control section 1, but can also manage and operate independently.

Therefore, the central control unit 1 corresponds to TTC and CTC in the case of train operation, and corresponds to the main computer room in the general command room in the case of aircraft operation. In the case of aircraft, it is prepared for the first and second offices or domestic and international flights.

2 is a detailed diagram of the local configuration. The signal sent from the host computer 1A includes data and current time signals including the plan and contents of the guidance. The current time signal is received by the clock converter 5C and the display clock is displayed. It converts into a signal that can be recognized to drive the display clock, and can be corrected in each area by an external adjustment terminal.

Then, the information related to the display of the comprehensive guide indicators 8 ^l- 8 ^m and the guide indicators 9 ^l- 9 ^L is received by the local computer 5A of the regional control unit 5.

The local control unit 5 is composed of a keyboard and a monitor 5B, etc., in which the monitor modifies the display plan or indicates a malfunction, centering on the local computer 5A.

The local computer 5A collectively manages the guide indicators of each local section 5, analyzes the signals sent from the host computer 1A, and monitors whether they are being executed normally by the signals received from the position detector 7, thereby providing a comprehensive guide indicator. (8 ^l -8 ^m ) and the indicator (9 ^l -9 ^L ) and the automatic broadcasting device (4).

The position detector 7 is a sensor (SENCER) that detects the arrival and departure of a train in the case of a train, and a sensor installed in the boarding machine in the case of an aircraft to detect the approach state of the aircraft, and is analyzed and processed by the second interface controller 6B. Send to computer 5A.

In order to eliminate the boredom of the users and to stabilize the emotions, the video images such as natural scenery, animals, plants, news and sports broadcasts are displayed and broadcasted in connection with the automatic broadcasting system during the idle time without guidance. The local computer 5A makes progress.

When guiding several areas in one place in a public place, it is necessary to distinguish between crowded areas and diverged areas.

Therefore, in view of this, the present invention guides comprehensive and diverse information in the crowded area in the first interface controller 6A and the comprehensive guide indicators (8 ^l -8 ^m ), and the local area in the second interface controller ( 6B) and the information indicator (9 ^l -9 ^L ) display the relevant information.

By installing this system, the general information history indicator (8 ^l -8 ^m) is installed in the waiting room to run a comprehensive guide including destination information and instructions from the train, and a television broadcast or a video image, and guidance indicators (9 ^l -9 ^L ) Is installed at each Sungjiang, and trains arrive soon. This arrival train expresses information such as going to Busan.

Both the general information indicator (8 ^l -8 ^m ) and the information indicator (9 ^l -9 ^L ) have the same structure, but the area of the general information indicator is large.

3 is a detailed block diagram of the general guide indicator and the same configuration as the guide indicators 9 ^l -9 ^L.

Comprehensive guide display 81 can be divided into a functional unit for controlling the actual guidance data and a video signal unit for controlling the video signal which is a video screen, the graphic unit configuration is composed of the display central processing unit 31 and the graphic time controller 35, It consists of a REAL GRAPHIC RAM 36, an interface 40, and a display panel 82, and the image signal unit is an image source 10 as a signal source, a color decoder 11, and an image AD converter. 37), an image time controller 38, an image RAM 39, an interface 4, and a display panel 82;

The reference clicks needed for this configuration to work are supplied by the reference signal generator 34.

When the information display for the announcement is executed, the local computer 5A commands the graphic display.

The indicator central processing unit 31 receives this command and checks whether the present display state is a graphic state or an image signal and outputs a graphic signal for a command in a graphic state. Request to switch to graphical state.

The reference signal generator 34 outputs a reference clock pulse and a synchronizing signal required for the present invention general guide indicator to operate, and when switching from the image display state to the graphic state or vice versa, the display signal is instantaneously collapsed. Since the phenomenon occurs, the synchronization signal of the graphic and video signal states (GEN LOCK) so that the screen does not collapse. It has this GEN LOCK function.

When the indicator central processing unit 31 commands the graphic display to the reference signal generator 34, the reference signal generator 38 synchronizes horizontally and vertically with the clock signal provided to the image AD converter 37 and the image time controller 38. It blocks the signal and blocks the video signal flow.

And the form of graphic display is as follows.

When the command and the display data of the local computer 5A are received by the microprocessor 31A through the asynchronous serial input / output device (ACIA: 31A) of the display central processing unit 31, it is temporarily stored in the RAM 41B and the display graph currently in progress. When the routing is completed, if the newly received command is executed, the address of the corresponding character is assigned to the character generator 32 which is already memorized when the character is displayed, and the display central processing unit 31 reads the graphic RAM 33 Or stored in the real graphics RAM 36 under the control of the graphic time controller 35.

This signal is output to the interface 40, and since the graphic is already selected so that only the graphic is output, the graphic signal is sent to the display panel 82 to turn on the corresponding LED, so that the guidance is made.

In addition, in the case of displaying a video screen, the clock signal provided by the signal generator 34 to the graphic time controller 35 is blocked, and the clock signal is supplied to the image AD converter 37 and the clock signal is applied to the image time controller 38 as opposed to the graphic display. Resume the horizontal and vertical sync signal supply.

Since the video signal output from the video equipment 10 such as a video camera or a VTR is a synthesized video signal, the color decoder 11 outputs the red, green, and blue signals separately from the video signal and the synchronization signal. The signal and the image AD converter 37 are supplied with color signals, respectively.

The image AD converter 37 converts the analog color signal output from the color decoder 11 into a digital signal, and the image time controller 38 distributes the screen configuration of the display panel 82 in a balanced manner. Store digitalized image data.

In addition, the image screen and the graphic screen may be overlapped and displayed, and the output of the reference signal generator 34 may be adjusted by a command of the display central processing unit 31.

The power supply 84 is a sensor 83 connected to a power supply line. The sensor 83 detects an amount of current when the display panel is operated. The power supply 84 detects an estimated current value of the graphic screen that is distorted by the display central processing unit 31 and the detector 83. By comparing the current amounts, it is possible to determine whether the destination guide indicator 81 is abnormal and recognize the operator without checking the display state of the display panel.

5 is a detailed circuit diagram of the graphic time controller 35. As shown in FIG.

This causes red, green, and blue data to be scanned on the display panel 82 and outputs the address signal of the real graphics RAM 36.

The basic click signal is received from the reference signal generator 34 and counted at the clock counter 35A and operates as a 16 counter because it is 4 bits (BIT; RAO-RA3).

Clock Counter (35A) Output RAO-RA3 is used as multiplexer (36Z-36H) counter signal of Real Graphics RAM 36. Module 1 consists of 16 x 16 dots horizontally and vertically. To scan a line.

The display device driving method of the display panel is largely divided into a static method and a dynamic method. In the static method, a dynamic method of scanning a signal is generally used because the driver device cannot be efficiently used.

The present invention also uses the clock signals supplied from the reference signal generator 34 as the basic clocks to scan graphic signals in a dynamic manner and sequentially transmit the graphic information stored in the RAM to the display panel 82. The counters 35D, 35C, 35P sequentially outputs the addresses SA0 to SA10 of the real graphics RAM 36.

The selector 35F is used to change the display graphic data, and selects input A to select the counters 35B, 35C, and 35D when the display text is not required to be changed.

SW ₁ , SW ₂ , and SW ₃ select initial conditions of the counters 45B, 35C, and 35D and select switches according to the size of the display panel 82.

The graphics RAM 33 is a memory board for storing various screens, and the real graphics RAM 31 reads and stores graphic data to be displayed immediately.

6 is a circuit diagram of the real graphics RAM 31.

The color RAMs 36A, 36B, 36C, and 36D are separately stored for each color according to the address designated by the graphic time controller 35, and the I-RAM (RAM) 36D is luminance data.

The multiplexers 36E, 36F, 36G, and 36H convert parallel data of D0-D15 into serial signals and are transmitted to the LED module of the display panel 82 through the interface 40.

7, 8, 9, and 10 are circuits operated when displaying an image screen which is a video signal.

The color decoder 11 outputs the output of the imaging device 10 to the red, green, and blue luminance signals, which are the three primary colors of light, and the synchronous signal, and is converted into a digital signal because it is an analog signal.

The image AD converter 37 at this time plays a role.

The signal for each color separated by the color decoder 11 is input to a differential comparator 87A having an operational amplifier as a differential comparator, and another operational amplifier 47B provides a reference signal to the differential comparator 37A.

The compared output is input to the AD converter 37C, and a predetermined section is determined according to the reference clock frequency supplied from the reference signal generator 34, and the level value is output digitally.

Since the output of the AD converter 37C of FIG. 7 is shown as 4 bits, 16-level brightness can be adjusted for each color, and total 4096-level brightness control of 16 x 16 x 16 is possible because of three colors of R, G, and B. have. However, where finer brightness control is required, increase the number of output bits in the AD converter. In the NTSC system adopted by Korea for image display, the number of scan lines is 525 lines or the interlaced scan, so the number of shot players per field is 262.5 lines.

When scanning red, green, and blue data on the display panel 82, the horizontal and vertical synchronizing signals must be matched with the scanning player of one field, and when the display panel LED dot number is smaller than the scanning player, the center part of the screen is displayed on the display panel and the screen is unbalanced. Should be eliminated.

The image time controller 38 of FIG. 8 serves as such a screen distribution, and a clock, a horizontal synchronizing signal HS, and a vertical synchronizing signal VS which are used as signals are provided from the reference signal generator 34. Counters A and B (38A, 38B) count the clock and horizontal sync signal (HS) to designate the RAM address of the image RAM 39, and counter C (38E) uses the twelfth bit (A12) of the RAM address as the clock signal. 16 counters and allow the image RAM 39 to operate sequentially.

The principle of brightness adjustment of the display panel LED is that if brown and one pixel correspond to one LED, when 16 levels of brightness control is performed, 16 times of time corresponding to one field is scanned 16 times when the brightness is the highest. In the lowest case, all 16 times are turned off to adjust the brightness.

9 is a circuit diagram of an image RAM 39 that stores digital image color data. The 1, 2, 4, 8 signals are used as the comparison signal with the color data (DO-D15), and the comparator 39C compares the data including the luminance signal with the 1, 2, 4, 8 counter signals and sequentially signs ( 82).

The horizontal synchronization signal reduction circuit 38C and the vertical synchronization signal reduction circuit 38D of FIG. 8 adjust the widths of the horizontal (HS) and vertical synchronization (VS) signals so that the center portion of the screen is displayed on the display panel. 11 is a horizontal synchronization signal reduction circuit.

When the horizontal sync signal HS is input and the flip-flop A 60 output Q becomes logic 0, the counter 62 counts the clock signal, counts the number of clocks selected by SW1, and the NAND gate 63 resets the logic 1. Output to clear flip-flop A (60).

Therefore, since Q of flip-flop A 60 is inverted to logic 1, the counter 62 does not count, and the output Q of flip-flop B 61 transitions to the logic 1 state so that the clock signal is transmitted to the display panel and the horizontal of the sign is displayed. When the clock signal is transmitted by the number of LEDs, the horizontal synchronizing end signal is input to the clear (CL) terminal of the flip-flop B (61) and the output Q is inverted to logic 0, so that the click is blocked.

Accordingly, the horizontal synchronizing signal reduction circuit 38C controls clock pulses allocated to one scanning line to block unnecessary screen left and right data, and the vertical synchronizing signal reduction circuit 48D adjusts the scanning line up and down.

10 is part of the interface circuitry and is driven by a signal adjusted from the image time controller 38.

Bright signal (BRI-BRm) prevents the left and right LEDs of the LED that are lit when the display panel LED module operates at high speed and adjusts the overall brightness by a counter of 40, which is a non-explanatory code.

Reference numerals 40A and 40B denote decoders and 40C and 40D counters.

FIG. 12 is a block diagram of the LED module attached to the display panel 82. Since the display elements are red, green, and blue light emitting diodes (R, G, B LEDs: 82G), which are the primary colors of light, total natural colors can be expressed.

Therefore, the present invention is an industrialized urbanization, accurate and prompt information is required, while the emotionally unstable with less opportunities for contact with nature, as well as quick guidance, as well as express the voice combined with a fresh screen close to full color emotional stability emotional stability It is possible to create a fresh urban culture, and on the other hand, it is possible to flexibly utilize various systems by providing comprehensive management control with various screen configurations and colors in various guide posts, advertisement contents, and promotion contents among numerous remote locations. It is a beneficial feature that can be expected widely.
