理量は、膨大な量になるので、端末装置の異動に
対する対応が能率的ではなかつた。 Therefore, in the conventional method of reading the meter reading data of individual terminal customers from the meter reading data collected based on the terminal address, a conversion table is required to index the terminal address and match the customer address. In addition, in the case of frequent new installation, removal, or movement of terminal equipment, or changes such as changing the way distribution lines are laid,
The central device also had the problem of having to perform complicated processing to change the conversion table each time. In other words, it is necessary for both the terminal device and the central device to respond to changes in terminal devices.Moreover, in areas where customers move frequently, such as large cities, it is necessary to handle changes in the conversion table in the central device. Since the amount is enormous, it is not efficient to deal with changes in terminal equipment.

徴とする。 In order to achieve this objective, the present invention sets a terminal address for each terminal device, and also sets a customer address unique to the customer where the terminal device is installed, so that the central device or relay A terminal address signal is sent from the device to the terminal device, and the terminal device, in response to the terminal address signal, returns a data signal including the customer address signal to the central device via a relay device or directly. The present invention is characterized in that the terminal device is provided with a customer address generation function, thereby eliminating the need for a conversion table in the central device.

実装になつたことを報告する。 Normally, all the terminals registered in the memory section 2 of the central device 1 are not used as mounted terminal devices, so unmounted terminal devices can be easily
Although it can be newly installed as a mounted terminal device, in this case as well, all that is required is to return the meter reading data along with the customer address, and even when the mounted terminal device is removed, the data return for the corresponding customer address will be stopped. This eliminates the need for corresponding processing in the central device 1, whether it is new installation or removal. At the site, in the case of new installation, a terminal device is installed at the customer, and one of the terminal addresses assigned from the uninstalled terminals is set in the terminal address setter 12 of the terminal device, and the customer A customer address unique to the customer is set in the address setting device 14. These Ares configuration tasks are
When the worker goes to the site to install the terminal device, this is done at the same time, so it does not take much time. In addition, in the case of removal, the terminal device is removed and taken home, and a report is made that the terminal address of the terminal device is no longer installed.
