Abstract

PROBLEM TO BE SOLVED: To change ID numbers in order and to efficiently write them without miswriting by determining the identification number (ID number) of the start of writing according to an inputted initial value and outputting an ID number code corresponding to the ID number, and outputting a write signal corresponding to the ID number code. SOLUTION: An identification number code output part 11 outputs the ID number code corresponding to the ID number inputted to an identification number code output part 11 to a write signal generation part 13. The write signal generation part 13 after outputting a digital signal in timing corresponding to the received ID number code to an article 2 automatically outputs an increment signal to the serial number code output part 11. The identification number code output part 11 having received the increment signal increases the current ID number in the identification number code output part 11. Therefore, such missetting that an ID number is set repeatedly by mistake can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an identification number registration device for writing unique identification numbers different from one another into a microcomputer.

[0002]

2. Description of the Related Art For example, when it is desired to recognize a unique identification number, that is, an ID number, which is different for each product, even though the products are identical in appearance and internal circuit, but are incorporated in the product. There is.

Conventionally, in such a case, a dip switch (having a plurality of on / off switching switches) is mounted inside a product, and each of the dip switches is turned on / off. By turning on / off according to the desired address, the address terminals of the microcomputer are individually pulled up or down, and the ID number is set by a combination of LOW and HIGH of the address terminals.

In some cases, the address terminals of the microcomputer M are individually pulled up or down according to the presence or absence of a jumper J without using a dip switch, as shown in FIG. The ID number was set by the combination of LOW and HIGH of the address terminal.

[0005] In recent years, however, a microcomputer (for example, UPD754304) which directly writes and stores an ID number in a chip has been used. However, in a microcomputer in which the ID number is directly written and stored in the chip,
Other program codes except for writing the ID number are:
It is written in advance by the microcomputer manufacturer and delivered to the assembly company. Therefore, the assembly company adds a microcomputer supplied by the manufacturer to the microcomputer.
It becomes necessary to write the D number.

[0006]

However, in the past, there was no microcomputer which writes only an ID number in an assembly company. Therefore, there is no device for writing only the ID number into the microcomputer, that is, no recognition number registration device. However, the assembly company must write the ID number on the microcomputer. However, what an assembly company has experienced writing with a product using a microcomputer is simply to repeatedly write exactly the same program code in a P-ROM.

[0007] That is, the conventional assembly company is not accustomed to writing while changing the ID number to the microcomputer of each product in turn. Therefore, in order to efficiently write the ID number without making a mistake in writing, the ID number to be written is automatically incremented, and the incremented ID number is automatically written in the ID number writing section of the microcomputer. However, there is a problem that an identification number registration device is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a microcomputer in which, except for writing an ID number, other program codes are written in advance by an ID number of a microcomputer. It is an object of the present invention to provide an identification number registration device capable of sequentially changing an ID number and writing efficiently without erroneous writing.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to the first aspect of the present invention, wherein an initial value input section for inputting an initial value of an identification number is provided. A recognition number code output unit for determining a recognition number for starting writing based on the initial value and receiving a count-up instruction, incrementing the recognition number, and outputting a recognition number code corresponding to the recognition number; And a write signal generation unit that outputs a write signal corresponding to the identification number code output by the unit.

The invention according to claim 2 is characterized in that a number display for displaying the identification number is added.

Recognize as [0].

The write signal generation unit 13 outputs a digital signal of a timing corresponding to the received ID number code from the write signal output unit F to the microcomputer (UPD
754304), an increment signal is automatically output from the count-up signal output unit E to the count-up signal input unit C of the identification number code output unit 11. Upon receiving the increment signal, the identification number code output unit 11 increments the current ID number inside the identification number code output unit 11. In addition, the identification number code output unit 11 transmits the ID number display 1 from the display connection unit A.
For 2, an ID number code corresponding to the incremented current ID number is output. The ID number display 12 receiving the ID number code displays the current ID number of the identification number code output unit 11 in decimal.

Therefore, the worker who writes the ID number removes the product 2 for which the ID number has already been written, and sets a new product 2 on which the ID number has not yet been written. Then, the worker writing the ID number presses an ID number write command switch (not shown) provided in the identification number registration device 1 while checking the ID number displayed on the ID number display 12. Then, the identification number code output unit 11 outputs the ID incremented earlier.
An ID number code corresponding to the number (the ID number displayed on the ID number display 12) is output from the identification number code output unit B to the identification number code input unit D of the write signal generation unit 13. Upon receiving the ID number code, the write signal generation unit 13 sets the received incremented I
A digital signal at a timing corresponding to the D number code is output from the write signal output unit F to the 24th, 25th, and 26th pins of the microcomputer (UPD754304) inside the product 2.

Thereafter, by repeating the same operation as described above, the automatically incremented ID numbers can be sequentially written to the product 2 for which the ID numbers have not been written, and the ID numbers are mistakenly duplicated. In addition, the ID number display 12 displays the ID number to be written, so that the ID number setting can be eliminated.
