Abstract

PURPOSE:To achieve a higher efficiency and accuracy of metering work by providing a bar code display section for displaying an integrated value by a bar code in the measurement of a flow rate while a bar code reader is used to read and record the integrated value simultaneously. CONSTITUTION:A flow rate signal measured with a flow rate sensor 7 enters a flow rate integration circuit 8 to be integrated and an integrated value is inputted into a bar code conversion circuit 9 to be converted into a bar code signal, which is displayed on a bar code display section 4. At the same time, the integrated value integrated with the circuit 8 is displayed on a numerical display section 3. This achieves a higher efficiency and accuracy of metering work.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a system that supplies energy such as gas, electricity, water, hot water, or refrigerant via piping, and measures the amount of this supply. , and relates to a system for reading the integrated value of a flowmeter, which is used when integrating the value and using it as the basis for calculating charges.

[Prior Art] As shown in Figure 3, conventional meter reading work for gas meters, etc., involves a meter reader reading the integrated value displayed on the display section of gas meter a, writing it on a slip, or using a handheld tally device. In most cases, the information is input into the system and taken back to the fee calculation center.

[Problems with Prior Art] Therefore, misreading, writing errors, and input errors may occur. In addition, because meter readers read the meters for each house,
It requires a lot of effort and time.

From this point of view, there are proposals for automatic meter reading systems, but
It will take time to put it into practical use.

[Means for Solving the Problems J] The present invention is proposed in view of the above points, and the meter reading work itself can be carried out by a meter reader for each house, or by visualizing the readings from the meters to avoid misreading, miswriting, etc. The feature is that it eliminates input errors, and its structure is as follows.

A flow rate integration circuit that integrates the flow rate measured by the flow rate measurement sensor, a display section that numerically displays the integrated value integrated by this flow rate integration circuit on a part of the flowmeter, and an integrated value integrated by the flow rate integration circuit. A barcode display section that displays the totalization value as a barcode on a part of the flowmeter, and a barcode reading circuit that reads and records the totalization value displayed on the barcode display section. Value reading system.

In the above configuration, the means for measuring the flow rate of gas is not particularly limited, and may be a membrane gas meter or a full-volume gas meter 6 in the case of gas.

Further, the means for displaying on the display section may be any conventional mechanical counter or liquid crystal display means.

[Operation] The integrated value calculated by the flow rate integration circuit that measures the flow rate and integrates the flow rate in parentheses is displayed as a numerical value on the display section and also on the 8-code display section.

On the other hand, the meter reader reads the data using an eight-coat reading circuit (barcode reader), records it, and takes it back to the calculation center, or sends it to the calculation center via a communication line.

Although only the integrated value has been described above, necessary information such as the customer code and meter number may also be displayed as a bar code and read.

[Example] Fig. 1 is a conceptual diagram of the present invention, l is a gas meter, 2 is a display section, here is a numerical display section 3 that displays the integrated value in numbers, and a bar code that is displayed in barcodes. A display section 4 is provided.

5 is a barcode reader for reading the barcode displayed on the barcode display section 4, and 6 is a reader.

FIG. 2 shows the circuit configuration of the gas meter l and barcode reader 5. The flow rate signal measured by the flow rate sensor 7 enters the flow rate integration circuit 8, where it is integrated, and then this integrated value is sent to the barcode conversion circuit. 9, the signal is converted into a barcode signal and displayed on the barcode display section 4. At the same time, the integrated value integrated by the flow rate integration circuit 8 is displayed on the numerical display section 3.

IO is a reading circuit 11 for reading a barcode signal input from the head 6 of the barcode reader 5;
is the recording circuit.

In the case of the embodiment, it is also possible to read the integrated value by wire by connecting the gas meter 1 and the barcode reader 5 with a connector.

[Effects of the present invention] As described above, the present invention provides a barcode display section on the flowmeter side that displays the integrated value in barcode, and the meter reader uses the barcode reader to read the integrated value and simultaneously reads the integrated value. Since it is recorded, there is no possibility of misreading, writing errors, or input errors when reading and recording integrated values, and it is therefore possible to improve the efficiency and accuracy of meter reading work.

Furthermore, since the flowmeter has a separate display section that displays numbers, it is convenient for consumers to be able to read the integrated value using these numbers.
