Abstract

PURPOSE:To make the name of an intersection corresponding to an intersection parameter being displayed quickly and surely confirmable by providing a means which displays the name of an intersection upon receiving data of a character font and simultaneously displaying the name and parameter of the intersection upon receiving intersection parameter data from the outside. CONSTITUTION:A CPU 1 reads out dot data corresponding to intersection name data received from a Kanji (Chinese character) font data memory 3 one character by one character and stores in a prescribed area of a RAM 4 for displaying street intersection names. When the final dot data are stored in the RAM 4, the CPU 1 outputs the dot data to an intersection name displaying section to display an intersection name. Since a character font data storing means and the means which displays an intersection name upon receiving data of a character font are provided, intersection names can be displayed in KANJI (Chinese character) instead of numbers which have been used for the conventional example and, when a parameter displaying section 7 is used, the accuracy and instantanity can be improved. Therefore, the data being displayed can be confirmed instantaneously and surely.

Description

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 a list of intersection numbers versus intersection names.

Problems to be Solved by the Invention However, the conventional intersection parameter display device described above only displays numbers and does not display the intersection name corresponding to the intersection parameter being displayed. There were problems in terms of gender and accuracy.

The present invention solves these conventional problems,
The purpose of this invention is to provide an excellent intersection parameter display device that can quickly and accurately confirm the intersection name corresponding to the intersection parameter being displayed by displaying the intersection name (in kanji) and the intersection parameters at the same time. be.

Means for Solving the Problems In order to achieve the above objects, the present invention provides means for sequentially inputting and storing intersection name character (kanji) code signals from the outside, and characters (kanji) corresponding to the character (kanji) code signals. Font data storage means, memorized intersection name characters (kanji)
A means for converting the code into character (kanji) font data and storage, a means for sequentially outputting the converted and stored intersection name character font data, and a means for receiving the character font data and displaying the intersection name are provided. Intersection name (kanji) based on intersection parameter (number) data
and the relevant intersection parameters are displayed at the same time.

Operation The present invention has the following effects due to the above-described configuration. That is, by displaying the intersection name (in Chinese characters) and the intersection parameter at the same time, it is possible to quickly and accurately confirm the intersection name corresponding to the intersection parameter currently being displayed.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In Figure 1, 1 is a microprocessor (hereinafter referred to as CPU).
), and the CPU has program memory (ROM).
, RAM) 2 are connected. 3 is Kanji font data memory (ROM), 4 is buffer memory (RAM)
), 5 are I10 ports, each connected to one CPU.

The I10 boat No. 5 inputs intersection name data and parameter data from the outside, is connected to an intersection name display section No. 6, and a parameter display section No. 7, and outputs the respective display data.

An example of the data structure and character structure of the intersection name data is shown in FIG.

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

The CPU constantly checks the presence or absence of received data of intersection names through the I10 port (step 11). C.P.
When U confirms that the intersection name data has been received, it judges whether each byte of the received data is accurate as a kanji code (step 12), and if it is accurate, it stores the data in the buffer; step 13) if it is not accurate, it receives it. The data is ignored and blank data is stored in the buffer (step 14). Subsequently, the CPU receives the intersection name data one byte at a time and stores the received data in the buffer as the intersection name until the final data arrives in the received data (step 15).

Next, the CPU reads door data corresponding to the intersection name data received from the kanji font data memory one character at a time (step 16), and stores it in a predetermined area of the RAM for intersection name display. After storing the dot data up to the final data in the RAM (step 17), the CPU outputs the dot data to the intersection name display section to display the intersection name (step 1B).

When the CPU receives the intersection parameters, it outputs the data to the parameter display section (step 19).

The CPU maintains the display of the intersection name until it receives the intersection name data next time.

As described above, according to the above embodiment, by having the character font data storage means and the means for receiving the character font data and displaying the intersection name, the intersection name can be displayed in Chinese characters instead of the conventional number display. 1, accuracy and immediacy can be increased when using the parameter display device.

Effects of the Invention As is clear from the above embodiments, the present invention has the advantage that by displaying the intersection name and the intersection parameters at the same time, the data being displayed can be confirmed immediately and accurately.
