[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal system mainly used for an automatic meter reading system for transmitting and receiving signals between a center device and a meter reading meter via a telephone line.

[0002]

2. Description of the Related Art Conventionally, as an automatic meter reading system, as shown in FIG. 6, a center device 4 installed in a gas company or the like by a telephone line 3 through a terminal network control device 2 via a terminal network controller 2 as shown in FIG. A transmission system is used. The meter reading meter 1 is connected to the terminal network control device 2 to store and transmit measurement information of the amount of use of a supply source such as gas, water, and electricity, and to perform cutoff control of the supply source by a cutoff mechanism. . The terminal network control device 2 is generally installed on the outer wall of each house and connected to the telephone line 3 that is drawn into the house 12. The terminal network control device 2 is connected to the meter meter 1 by an electric wire 5 and connected to the meter meter 1 via the electric wire 5. Data communication and data communication with the center device 4 via the telephone line 3 are performed. 6
Is a meter remote control, which is usually installed in the user's house 12 and is connected to the meter reading meter 1 by an electric wire 7 to display a meter reading value of the meter reading meter 1 and to control a cutoff mechanism. 8
Is an abnormality monitoring sensor such as a gas leak alarm.
And the wire 9.

According to the above-mentioned conventional configuration, the meter reading value of the meter meter 1 and the state information of the shut-off mechanism are transmitted from the terminal network control device 2 to the center device 4 via the telephone line 3, and the electric wire 7 is connected to the meter remote controller 6. Transmitted via Further, a signal from the abnormality monitoring sensor 8 is also transmitted to the meter meter 1 via the electric wire 9, and the meter meter 1 controls the cut-off mechanism or is transmitted to the center device 4 by the telephone line 3 via the terminal network control device 2. Make a report.

In addition, instead of connecting the meter remote controller 6 to the meter reading meter 1 by the electric wire 7, the meter remote controller 6 is connected to the terminal network control device 2 by the electric wire 10. Similarly, instead of connecting the abnormality monitoring sensor 8 to the meter reading meter 1 with the electric wire 9, the abnormality monitoring sensor 8 is connected to the terminal network control device 2 with the electric wire 11.
