Description

  The present invention sets a wireless IC tag to be connected to a control microcomputer in a flow meter such as a water meter, an electronic meter, a gas meter, etc., and the data stored in the wireless IC tag and the wireless IC The present invention relates to a flow rate measuring instrument metering system that reads or prints data acquired after tag operation so that the data can be displayed or printed and can be metered from outside the box, and a metering operation stick used therefor.

  Conventionally, the flow meter measuring instrument metering system, for example, as in the invention of Patent Document 1, transmits the accumulated value data stored in the gas meter by radio frequency radio waves from the handy terminal and stores it in the handy terminal, and the meter management number, A system has been used in which management data such as replacement date is stored and read and written as needed.

Also, as in the invention of Patent Document 2, an RFID tag storing individual information is provided in each flowmeter, and the individual information stored in the tag is read into the electronic computer by the reader / writer by the electronic computer provided with the RFID reader / writer. There has also been proposed a meter reading system in which a current meter reading value of a flow meter is input to calculate a difference from the previous meter reading value, and the current meter reading value is stored in a tag.

  However, in any of the above conventional meter reading systems, the meter reader opens the cover of the meter box or the like and visually confirms the necessary items, or acquires the meter reading result information systematically unless the necessary items are input to the handy terminal. Can not do it.

  Since the meter reader goes to the meter reading area and goes through each flow meter according to a predetermined order, the opening and closing work of the cover of the meter box, etc., consumes a great deal of physical strength, and the meter box existing on the ground plane can be confirmed. For this reason, the posture of squatting or standing has to be repeated many times, and the work is fatigued.

  The present invention is intended to address the above-described problems, and sets a wireless IC tag in which required individual information is stored in each flow measurement device to be metered, and a control microcomputer provided inside the device; The wireless IC tag is connected, and the meter reading operation and the meter reading are performed by the proximity operation of the reader / writer.

  By configuring the meter reading system in this way, the meter reader can read the meter by simply bringing the transmitter / writer transmission mechanism close to the place where the wireless IC tag of the flow meter is set. Meter reading can be performed without any opening / closing operation.

  In addition, the wireless IC tag is configured to be set not on the flow measurement device itself but on the lid portion of the flow measurement device storage box, so that the transmission / reception effect of the reader / writer is enhanced and a valve attached to the flow measurement device or piping device is provided. The electric valve is set so that the electric valve can be opened and closed by the proximity operation of the reader / writer so that it can be used for purposes other than meter reading.

  Further, a reader / writer is provided with a stick-shaped transmission / reception mechanism so that the meter reading operator can operate without bending his / her waist, and in addition, a display unit for displaying or printing read data on the reader / writer main body or By providing a printing mechanism or both, the meter reading operator can operate efficiently by performing the proximity operation of the reader / writer while standing.

  Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a wireless IC tag, which is embedded in the upper end portion of the electronic meter A as shown in FIG. 1 or the lid portion of the water meter housing box B as shown in FIG. The control microcomputer 2 is connected.

  Individual information such as the serial number of each electronic meter is stored in the wireless IC tag 1 in advance, and information accumulated in the control microcomputer 2 after the operation of the wireless IC tag is collected by connecting to the control microcomputer 2. It has come to be remembered.

  There are two types of wireless IC tags: a battery-mounted type and a battery-less type. In the present invention, it is advantageous to use a battery-less type by utilizing a reader / writer battery.

  When the reader / writer 3 is brought close to the wireless IC tag 1, a voltage is induced in the antenna coil of the wireless IC tag by electromagnetic induction between the antenna coil of the wireless IC tag and the transmission antenna coil 32 of the reader / writer. The wireless IC tag is activated, the individual information such as the serial number of each electronic meter is read and confirmed by the reader / writer, and the CPU on the reader / writer side for the predetermined data from the control microcomputer 2 acquired by the wireless IC tag ( Communication of information with the central processing unit).

  By this communication of information, the information stored in the wireless IC tag 1 is read through the control microcomputer 2, and the meter reading operation is completed.

  As the reader / writer, a handy terminal configured in a remote control type is usually used. However, in the present invention, as shown in FIG. A built-in stick 31 is attached and formed.

  Since the present invention is configured as described above, the reading of the meter is performed only by bringing the transmitting mechanism of the reader / writer close to the place where the wireless IC tag of the flowmeter is set without performing the opening / closing operation of the cover. In addition, the meter reader can perform the meter reading work quickly and efficiently with an easy posture while standing.
