DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an intersection parameter display device used for traffic control map boards and the like.

2. Description of the Related Art Conventionally, this type of intersection parameter display device displays an intersection number and the intersection parameters, and the name of the intersection is confirmed by comparing the intersection number and the intersection name.

Problems to be Solved by the Invention However, in the conventional intersection parameter display device described above, the display indicating the intersection is only a numerical display, and the intersection name corresponding to the intersection parameter being displayed is not displayed in letters. There were problems with the immediacy and accuracy of checking intersection names.

The present invention is intended to solve such conventional problems, and is capable of simultaneously displaying the intersection name consisting of characters such as kanji and the intersection parameters, and quickly and accurately displaying the intersection parameters currently being displayed. The object of the present invention is to provide an excellent intersection parameter display device that allows the user to check the intersection name corresponding to the intersection name.

Means for Solving the Problems In order to achieve the above object, the present invention provides an intersection number corresponding character code memory that stores intersection name character codes corresponding to intersection numbers for the required number of intersections, and an intersection name character code that stores the intersection name character codes in character font data. A character font data memory that is converted into and stored, sequentially stores received data of intersection numbers inputted from the outside, and stores the intersection name character code read out from the character code memory corresponding to the intersection number, In addition, there is a buffer memory for storing dot data read from the character font data memory corresponding to the stored intersection name character code, and a buffer memory for storing the dot data read from the character font data memory corresponding to the stored intersection name character code. display means for displaying the data.

Operation The present invention has the following effects due to the above-described configuration. That is, by simultaneously displaying the intersection name in text and the intersection parameter data, it is possible to quickly and accurately confirm the intersection name corresponding to the intersection parameter being displayed.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In Figure 1, 1 is a microprocessor (in the daytime, CPU
This CPU is connected to a program memory 2 consisting of, for example, a read-only memory (hereinafter referred to as ROM) and a random access memory.

3 is an intersection number corresponding character code memory connected to the CPUI and stores the character (kanji) code of the intersection name corresponding to the intersection number for the necessary intersections; for example, a ROM-based character code memory corresponding to the intersection number; The data structure of the code is shown in Figure 2 (a),
C in the figure is a horizontal parity pit. Further, the character structure of the intersection name is as shown in FIG. 2(b), and P in the figure is a vertical parity pit.

4 is a character font data memory connected to the CPUI and converts the intersection name character code into character font data and stores it; for example, a ROM-based character font data memory; 5 is a CPU
It is a buffer memory that exchanges data with the CPU.
It stores received data of intersection numbers transferred from I.

Further, 6 is an input/output port (hereinafter referred to as I10 port) that exchanges data with the CPUI, and is a terminal 6a.
Intersection number input manually from outside through CPUI
At the same time, intersection parameter data is input from the outside through terminal 6b, and the data is transferred to the CPU.
It is designed to be transferred to I.

7 is an intersection name display section connected to the output end of this I10 port 6, which displays the intersection name;
is a parameter display section connected to the output end of I10 port 6 and displaying intersection parameters.

Next, the operation of the above embodiment will be explained with reference to the flowchart shown in FIG.

First, in step 11, the CPU 1 checks whether there is reception data of the intersection number through the terminal 6a of the I10 port 6. When the CPU 1 confirms the reception of the reception data of the intersection number, it returns Y(rYEs J in step 11).
(abbreviation) side, the process proceeds to step 12, and if the reception data of the intersection number is not received, the process proceeds to step 11 N.
(abbreviation of rNOJ) side, the process proceeds to step 20, which will be described later.

In step 11, proceeding from the Y side of step 11 to step 12, in this step 12, it is judged whether the received data of the received intersection number is accurate as an intersection number for each byte, and if it is accurate, step 12
The process proceeds to step 13 from the Y side, and the data is stored in the buffer memory 5.

In addition, in the determination process of step 12, if it is determined that the received data of the intersection number is not accurate as an intersection number, the process branches from the N side of step 12 to step 14, and in this step 14, the received data of the intersection number is closely examined. , stores blank data in the buffer memory 5.

Next, the CPUI receives the intersection number reception data one byte at a time, and stores the reception data as the intersection number in the buffer memory 5 until the final data arrives in the reception data (step 15).
Store in.

In step 15, if the final data received is not stored in the buffer memory 5, the process returns to step 11 from the N side of step 15.

Furthermore, when the last received data of the intersection number is stored in the buffer 7 memory 5, from the Y side of step 15 to step 1
6, and in this step 16, the CPU
reads the intersection name character code from the intersection number received data by referring to the character-code memory 3 corresponding to the intersection number.
7. Store in buffer memory 5.

Subsequently, the process proceeds from step 16 to step 17,
In step 17, the CPU reads the dot data corresponding to the intersection name character code stored in the buffer memory 5 from the kanji font data memory 4 character by character, and stores it in a predetermined area of the buffer memory 5 for displaying the intersection name. do.

In this way, when the dot data up to the final data has been stored in the buffer memory 5, the process proceeds from the Y side of step 18 to step 19, but if the dot data of the final data is not stored in the buffer memory 5, From the N side of step 18, the process returns to step 17.

Also, the dot data is stored in the buffer memory 5 until the final data.
If the process proceeds to step 19,
The CPU 1 outputs the dot data to the intersection name display section 7,
The intersection name is displayed on this intersection name display section 7.

In addition, intersection parameter data is input from the outside to the I10 port 6 through the terminal 6b, and when the CPU 1 receives the intersection parameter data in step 20 through the I10 parameter 6, it outputs the parameter data to the parameter display section 8. and display it on the parameter display section 8. Then, the CPUI maintains the display of the intersection name until it receives the intersection name data next time.

In the embodiment shown in FIG. 1, the character font memory 4 is used, but a kanji font data memory may also be used.

Effects of the Invention As is clear from the above embodiments, the present invention includes an intersection number corresponding character code memory that stores intersection name character codes corresponding to intersection numbers for the required number of intersections, and a character code memory that stores intersection name character codes corresponding to intersection numbers and converts the intersection name character codes into character font data. It sequentially stores the character font data memory stored in the character font data memory and the received data of the intersection number inputted from the outside, and also stores the intersection name character code read from the character code memory corresponding to the intersection number, and stores the intersection name character code read from the character code memory corresponding to the intersection number. A buffer memory stores the dot data read from the character font data memory corresponding to the intersection name character code, and the dot data stored in this buffer memory is input to display the intersection name and at the same time, intersection parameter data is displayed. Since the present invention is equipped with a display means for displaying, by simultaneously displaying the intersection name in text display and the intersection parameter data, the intersection name corresponding to the intersection parameter being displayed can be quickly and accurately verified. I can do it.
