DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a setting device used for reading and setting data of an automatic meter reading meter such as a water meter, gas meter, or hot water meter.

[Prior art]

When installing a water meter or gas meter with a communication function for automatic meter reading, it is necessary to set and store data such as the ID number and the meter's guideline value in the meter's electronic circuit. Settings were made on the meter by connecting a setting device to the meter, operating the numeric keypad on the setting device, and inputting setting data.

Since the meter has a valid period of certification, it is necessary to replace it with a new meter when the certification expires. When replacing the old meter, the operator first reads out the data from the old meter using the setting device and records each item, then reconnects the setting device to the new meter, and manually inputs the recorded data for each item to the new meter. I was working on setting it to .

Furthermore, when replacing a meter, it was necessary for the worker to take a note of the old meter value and the new meter value, take it home, input it into the computer of the automatic meter reading center, and store the data.

[Problems to be solved by the present invention]

In the above conventional technology, when replacing a meter, the data read from the old meter is written down and recorded on paper, and when data is set in the new meter, the data is read from the paper and entered one by one using key operations. Not only is it easy to make setting errors due to misreading or pressing the wrong key, but it also takes a long time to set the data for all items.

Also, when writing notes on the old and new meter values, taking them home, reading them, and inputting them into the computer at the automatic meter reading center, there is a risk that errors may occur during collection operations such as reading, writing notes, and typing. Not only that, but there was also a problem in that it required a large amount of man-hours.

Therefore, it is an object of the present invention to propose a setting device that can solve the problems of the prior art.

In order to achieve the above object, the setting device of the present invention includes a terminal for connecting the old meter, a new meter, and a terminal network control device, a communication interface, and a terminal for connecting the old meter, or a communication interface for connecting the old meter to the terminal network control device. a changeover switch that connects a terminal to which the new meter is connected; a switch that connects the terminal to which the new meter is connected and a terminal to which the terminal network control device is connected; and a switch connected to the communication interface and connected to the changeover switch. It has a function to operate the switch, and is equipped with a control circuit that reads the data stored in the old meter and sets it to the new meter, and also activates the new meter to make a terminal call, and puts the switch in a connected state. It is characterized by this.

[Effect]

To use this setting device, connect the old meter, new meter, and terminal network control device to predetermined terminals of this setting device. The terminal network controller is connected to the automatic meter reading center through a telephone line.

When the setter is started, the control circuit operates a changeover switch to first connect the communication interface to the old meter and read the data stored in the old meter. Next, the control circuit operates a changeover switch to connect the communication interface to the new meter, and sets the previously read data from the old meter to the new meter. The control circuit further transmits a terminal call activation signal to the new meter to activate it, and closes the switch to connect the new meter to the terminal network control. Therefore, the new meter makes a terminal call and calls the automatic meter reading center via the telephone line, and once the connection is completed, the new meter reads predetermined data such as the old meter value and new meter value that it has stored. Automatically send to the automatic meter reading center.

The terminal network control device 6 shown in FIG. 2 has one end connected to the terminal 7 through a communication line 13, and the other end connected to a telephone line (not shown) through a communication line 14. A well-known automatic meter reading center is also connected to this telephone line. The positions of the movable contacts of the changeover switches SWI and SW2 are controlled by a control circuit 9. The control circuit 9 includes changeover switches SWI and SW.
In addition to the operations described in 2, there are functions such as reading the data stored in the old meter, sending the read data of the old meter to the new meter to set it, and starting a terminal call to the new meter. have.

The monitor 12 monitors data sent from the new meter 4 to the terminal network control device 6. Changeover switch SW2
has both the function of a switching switch for connecting the communication interface to the new and old meters, and the function of a switch for connecting the terminals 5 and 7.

Now, when a predetermined key of the keys 11 is pressed, the setting device 1 is started, the control circuit 9 operates the movable contacts of the changeover switches SIAi and SW2 to the positions shown, and the old meter 2 is moved to the position a of the changeover switch Ski. It is connected to a control circuit 9 via contacts and a communication interface 8, and data stored in the old meter is read by the control circuit 9 and displayed on a display 10.
Next, the control circuit 9 operates the changeover switch Ski to switch the movable contact to the b contact side and connect the communication interface 8 to the new meter 4. Then, the control circuit 9 transmits the previously read data of the old meter 2 to the new meter 4, and this data is set in the electronic circuit of the new meter 4. The data set in the new meter is immediately sent to the setting device 1 and the control circuit 9
The data will be verified.

The confirmed data is displayed on the display l9. The new meter stores the set old meter value and also stores its own meter reading value as the new meter value. The control circuit 9 further transmits a terminal call activation signal to the new meter to activate it, and switches the movable contact of the changeover switch SW2 to the b contact side. In other words, a switch S that connects terminals 5 and 7
Close W2. Therefore, the new meter 4 is connected to the terminal network control device 6.
The terminal makes a call to the telephone line via the terminal to call the automatic meter reading center. When the connection with the automatic meter reading center is completed, communication is established between the new meter 4 and the computer at the automatic meter reading center, and the automatic meter reading center is notified that the meter has been replaced, and the new meter value, according to the center's request, is sent.
Send the old meter value to the center.

The communication status is monitored on the monitor 12, and when the monitor determines that the communication has ended, "end" is displayed on the display 10, and the setting work and data collection work at the time of meter replacement are completed.

When replacing a meter, the terminal calling operation of the new meter is activated by sending a terminal calling signal from the setting device to the new meter.
When the connection with the center is completed, the new meter only notifies the center that the meter has been replaced, and the new meter value and old meter value are stored in the new meter's electronic circuit, and the next automatic meter reading is performed. The new and old meter values may be read out from the center and used.

Naturally, the meter for automatic meter reading using this setting device should be one that has the function of storing (setting) and transmitting the old meter value and new meter value as well as the normal communication function. In addition, it may be set so that terminal call activation is automatically performed by setting the new and old meter values, or a separate terminal call activation message may be determined and this activation message is sent to the meter. It may be determined that the terminal call is activated when the terminal receives the call.

Furthermore, the content displayed on the setting device at the end of the work is not limited to "finished" as mentioned above, but as a result of monitoring on the monitor, rNGJ
or "OK" may be displayed.

When installing a new meter for automatic meter reading, use a setting device to operate the tincture on-site to set only the ID number to the new meter, and then communicate with the center by making a terminal call to receive the necessary information from the center. Other data can be set.

〔Effect of the invention〕
