Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code which displays a changing bar code pattern on the basis of input data and allows a general bar code reader to read the changing data. The present invention relates to a conversion display device.

[0002]

2. Description of the Related Art It is widely practiced to read a bar code displayed on an article with a bar code reader and process the bar code.

FIG. 3 is a block diagram showing a configuration of a conventional bar code processing. In FIG. 3, 1 is a bar code reader, 3 is a data connection line, 4 is a data generation source, 5 is a bar code reading optical path, 6 is a bar code printer, and 7 is a bar code printed paper.

[0004] The data 3 of the data source 4 is printed on paper by a bar code printing device 6, read from a bar code printed paper 7 by a bar code reading device 1 via a bar code reading optical path 5, and processed. Is done.

Conventionally, for example, when the present invention is applied to a meter reading operation of a water meter, a meter number or a customer number which does not change is printed in advance with a bar code on paper or the like.
Barcode printed paper 7 using barcode reader 1
Thus, the data can be read through the barcode reading optical path 5.

However, in order for the bar code reader 1 to read the data of the data source 4 corresponding to the water usage, the usage data is once passed through the data connection line 3 by the bar code printing device 6. Each time, the barcode-printed paper 7 must be read and then read.

As described above, in order to read the data from the data source 4 with the bar code reader 1, it is necessary to strike out the paper 7 on which the bar code is printed by the bar code printer 6 through the data connection line 3 and then read it. there were.

[0008] Further, the above must be repeated each time the data of the data source 4 changes, and the input of the changing data is exclusively read visually and manually input.

[0009]

As described above, in order to input changing data, it is necessary to create or manually input paper 7 on which a barcode is printed every time the data changes. In addition, there has been an increase in input time and input errors.

Accordingly, the present invention provides a bar code conversion display device that changes in accordance with a change in data of a data source, and changes the data in the display device in response to an input, thereby providing the display device with the current data. Is displayed in the form of a bar code, so simply reading it with a bar code reader, it is possible to input data accurately without any hassle, and it is possible to prevent erroneous data input. A code conversion display device is provided.

[0011]

In order to solve the above-mentioned problems, a bar code conversion display device of the present invention converts input numeric data, character data or voltage value into a corresponding bar code and displays the converted bar code. Features.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described with reference to embodiments shown in the drawings.

FIG. 1 is a block diagram showing a case where the bar code conversion display device of the present invention is used, and FIG. 2 is an internal block diagram of the bar code conversion display device.

In FIG. 1, 1 is a bar code reader,
2 is a bar code conversion display device, 3 is a data connection line, 4 is a data source, and 5 is a bar code reading optical path.

Numeric data or character data from the data source 4 is input to the bar code conversion display device 2 through the data connection line 3. Barcode conversion display device 2
Each time the data input from the data connection line 3 changes, the input data is converted into barcode data by the barcode data conversion unit 9 built in the barcode conversion display device 2 to be re-created. The converted barcode is displayed on a barcode display device. As shown in FIG. 2, the barcode conversion and display device 2 includes a conversion unit 8 for converting input data into internal data, a conversion unit 9 for converting to barcode data, and a barcode display device 10.

In the bar code conversion display device 2 having the above-described configuration, the conversion unit 8 for converting input data into internal data is provided with bar code data capable of internally processing input numeric data, character data, and analog data. Convert to The barcode data conversion unit 9 sequentially converts the input data into barcode data, and the barcode display device 10 displays the barcode so that the barcode reader can read the barcode.

By repeating the bar code conversion and display of the data by the bar code conversion and display device 2, the bar code displayed on the bar code display device 10 always reflects the data of the data source 4 and the displayed bar code is displayed. By reading the code with the barcode reader 1, the current data of the data source 4 can be read.

As an example, when recording temperature data such as room temperature and refrigerator temperature while traveling around many places,
The necessary inputs are the location, temperature, date and time, and if the data is totaled and analyzed by a computer, a case where a barcode is used as a means for simplifying the input during patrol work is considered. If a barcode representing a place is created for each place in advance and the barcode is attached to the corresponding place, it can be read only when traveling to that place,
Location entry is complete. The date / time can be used if a clock is built in the barcode reader. Lastly, the temperature data is a choice of whether the patroller can visually enter and confirm the data manually, or use the mechanism of the present invention to input even the temperature data with a barcode. Obviously, the input can be made more quickly using the present invention.

According to the present invention, in addition to the above, not only analog data such as changing pressure, water level, current, and voltage, but also count information such as the number of productions and the number of presses, "OK",
Character information such as “NG” and “ALARM01” can also be applied to data that changes with data that can be converted into barcodes.

[0020]

As described above, according to the present invention, the following effects can be obtained.

(1) In the present invention, since changing data can be converted into a bar code, input can be performed without fail.

(2) It is not necessary to print bar codes on paper every time.

(3) The bar code of fixed data that does not change is printed on paper, and the changing data is input to a bar code conversion display device and displayed by bar code conversion. Is possible.

(4) The bar code reading mechanism established by the prior art can be used as it is, and changing data that could not be input can be input, so that significant labor saving and prevention of data input errors can be obtained. In addition, by inputting everything with a bar code, manual input to the bar code reader is eliminated, and input operation with only one hand is also possible.
