Description

Detailed description of the invention

Industrial application fields

  The present invention is based on a handy terminal equipped with an IC tag reader unit equipped with an IC tag in which the history information of the meter is stored in the verification of the meter and the customer who wants to perform meter reading at the time of meter reading work of the water meter. It is possible to collate and authenticate instantly and to improve accuracy, quickness and workability.

  The current status of identification and management according to the purpose of the individual water meter will be described with reference to FIG. Individual recognition of water meters, which is the basis for determining water charges, is performed with the meter number (manufacturing number) (5) stamped on the meter body at the time of shipment from the factory.

  The water meter is required by law to be replaced within 8 years from the time of shipment, and the date of shipment is strictly controlled along with the meter number.

  After this meter is delivered to the water utility, when a water supply application is made by each customer, an individual faucet number (owner number) (6) is attached, and a user number (water fee payment) The person will be marked (7).

  The faucet number (6) and user number (7) are not directly related to the management of the meter body, but when moving or removing the meter, these numbers are used to identify and manage the meter. It was cumbersome and centralized management was required.

  The meter reading work of the water meter is usually performed once every two months by visiting each house on a predetermined route (depending on the meter reading order of each customer).

  At this time, search, identification, authentication and verification of the target meter (individual customers who are stored in a handy terminal for meter reading carried by a meter reader or an information terminal having an equivalent function and are about to verify Read the meter number (5) marked on the meter body and read the meter number (5) of the handheld terminal for meter reading or a terminal with equivalent function. Displayed and read and verified both.

  Meter number (5) to be checked is 9 digits, and the local meter is buried underground, so it may be difficult to distinguish due to mud.

  The meter number is different when the meter is in trouble (when there is an obstacle such as a vehicle on the meter box, when you cannot enter the residential area due to absence, etc.) and the meter cannot be read or when the meter is replaced In the case of {circle over (5)}, the meter reader skipped the meter reading and moved to the next meter, and then revisited and changed the time or date.

  At this time, since the customer data of the handy terminal for meter reading or the information terminal having an equivalent function is inputted in the order of circulation, it takes time to investigate the data that has been skipped.

  Also, if the meter number (5) is different due to the exchange of the meter (8 years after shipment), the final guideline value and the start guideline value at the time of replacement are not known, so return to the water office for investigation. In addition, the amount of water used was calculated.

  Since the handy terminal for meter reading or an information terminal having an equivalent function is a system that can input the meter reading value without going to the site (the meter concerned), the data can be intentionally created.

Problems that the device tries to solve

  Water charges are set by visiting a house and reading the water meter installed on each customer's water supply pipe. At this time, a collation work for searching, identifying, and authenticating the customer and the meter is required.

  Specifically, it is an operation for searching, identifying, and authenticating the meter and the data stored in the handheld terminal for meter reading carried by the meter reader at the site of the meter reading work or an information terminal having an equivalent function.

  This collation work is performed by visually confirming the 9-digit meter number (manufacturing number) {circle over (5)} stamped on the meter body when the meter is manufactured.

  However, the 9-digit printed numbers are small and difficult to read, and the place where the meter is installed is often muddy with rainwater because it is underground, so it is very troublesome to read.

  In addition, there is a demand for a system capable of quickly and accurately collating the display of the device storing the customer data to be searched for because it is outdoors and sunlight is difficult to read.

  A handy terminal for meter reading for inputting / outputting data or an information terminal having an equivalent function can input a meter reading value without going to the site and can intentionally create data, and this improvement has been desired.

  The water meter is required to be replaced within 8 years from the date of manufacture, and is controlled by the meter number (manufacturing number) (5) given at the time of manufacture.

  After that, when using this meter, the faucet number (owner number) ▲ 6 ▼ and user number (payment fee payer) ▲ 7 ▼ are added, making it difficult to understand and complicated. There is a need for a system that can instantly recognize three individual numbers for the meter.

Means for solving the problem

  This device attaches a passive IC tag storing meter history information to a water meter, devise a handy terminal that reads, verifies and authenticates it, enabling quick, accurate and rational water meter reading. It is.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows the implementation details of a passive (battery-less) IC tag part. The IC tag part has a structure that can be easily attached to a place that is easy to see near the water meter body. Furthermore, the meter box for storing the meter has a waterproof structure so that there is no problem even if it is submerged.

  The IC tag unit receives electromagnetic waves from the reader unit added to the handheld terminal for meter reading or an information terminal having the same function by the IC tag RF antenna (1).

  The signal received by the IC tag RF antenna (1) becomes a DC power source by the rectifier circuit (2) and activates the RF transmission / reception circuit (3) and the information storage circuit (4).

  Meter information (manufacturing date, meter number, faucet number, user number, etc.) stored in the information storage circuit (4) in advance passes through the RF transceiver circuit (3) and the IC tag RF antenna (1) Are sent to a handy terminal for meter reading having an additional IC tag reader unit or an information terminal having an equivalent function.

  This electromagnetic wave is received by the RF antenna (8) of the IC tag reader unit added to the hand-held terminal for meter reading or an information terminal having an equivalent function.

  The received signal is detected by the RF reception detection circuit {circle around (10)} and is stored in the SD storage circuit {circle around (13)} and displayed on the display circuit {circle around (9)}.

  In this way, when the IC tag attached to the meter is read, the information on the meter is automatically displayed on the display of this machine, and collation work can be performed without a human hand by one-button operation or the like.

  Further, it is characterized in that the meter reading value cannot be input unless collation work is performed.

  Further, when necessary, new additional information can be input and set in the transmission information circuit (12) so that it can be written to the information storage circuit (4) of the IC tag section through the RF antenna (8).

Effect of device

As described above, the meter reading operation of the water meter is prone to human error, and the workability is reduced due to an imbalance in the volume of meter reading.
By adding an IC tag reader to the handy terminal for meter reading according to the present invention or an information terminal having an equivalent function and attaching a passive IC tag to the meter, it is possible to accurately and instantaneously collate.

According to the present invention, since intentional data creation cannot input the meter reading value unless the IC tag is authenticated, it is necessary to always go to the meter to prevent illegal meter reading.

  Each meter management was complicated in three ways, but the present invention can instantly authenticate at the site, greatly reducing the time and effort of organizing.
