DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution automation system, and more particularly, to a method for transmitting image character information as a part of improving customer service to consumers.

[0002]

2. Description of the Related Art Conventionally, communication of work involving power outages and the like has been carried out in writing, but in recent years, attention has been paid to the use of communication systems in order to achieve higher speed and more functions.
In such a case, in such a system, a terminal provided with a display device such as a liquid crystal is often installed in a customer's house to transmit work, fees, and the like. Further, there is a method of utilizing a television owned by a customer as a display in order to improve the visibility or reduce the cost of the terminal.

[0003]

However, in the above-mentioned conventional method, it takes time to transmit characters to be displayed on the television screen, and the user, that is, the customer, has a long waiting time to receive information. As a result, there is a problem that a user feels uncomfortable in operation and the capacity of the system is reduced. On the other hand, if a high-speed modem (modem) is used for information transmission, the transmission time can be shortened, but the cost of the system is increased, which is difficult to realize. Furthermore, a dedicated terminal equipped with a display such as a liquid crystal
When installing, not only cost but also new operation method
To give the user a sense of incongruity, such as the need to learn
It also becomes a factor that hinders the spread of the system. The present invention solves such a conventional problem, and can reduce information transmission time without increasing the price of the system.
Another object of the present invention is to provide an excellent information transmission method that can be easily operated .

[0004]

According to the present invention, in order to achieve the above object, the content of information is divided into a fixed information portion having a fixed expression format and a variable information portion which changes each time by operation. Then, the fixed information portion is stored in the terminal device on the receiving side, only the identification number for identifying the fixed information portion and the variable information portion are transmitted , and the information is reconstructed on the receiving side.
The generated information is converted to an RF signal and displayed on a television.
You.

[0005]

Therefore, according to the present invention, the fixed information portion is stored in the terminal to reduce the amount of information to be transmitted.
The transmission time of information can be reduced and the display of liquid crystal
Easy installation without installing dedicated terminal with indicator
Can provide an excellent information transmission method that can be operated
You.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of this embodiment.
In FIG. 1, reference numeral 11 denotes a line controller for managing lines and giving line use permission to each terminal; 12 a workstation for managing operations such as generation, management and storage of information;
Reference numeral 3 denotes a center side communication terminal as a main terminal disposed between the workstation 12 and the line, 14 denotes a line formed of a coaxial line, an optical fiber, or the like, and 15 denotes a dwelling unit reception as a sub terminal installed in each dwelling unit. A terminal, 16 is a power meter for measuring power consumption, and 17 is a television for displaying received information. The center-side communication terminal 13 and the dwelling unit-side reception terminal 15 adopt a method of realizing multi-channel access on a wire, perform mutual communication with the permission of the line control device 11 for line use, and perform one-to-one individual communication, It is configured to perform group or all-at-a-glance sibling communication.

Next, the operation of the above configuration will be described.
An information signal transmitted from the center side communication terminal 13 to the dwelling unit side terminal 15 originally required at least 130 characters for one screen. This information signal includes, for example,
As a notification of the power outage work, "Notice of power outage I understand that it is inconvenience, but we will have a power outage on the following date and time.-
・ ・ Electricity Co., Ltd. or as a notification of the usage amount, "Thank you for the notification of the current usage amount. The usage amount from the previous meter reading to the present is as follows ...
A fixed information part that is the same information, such as "Electricity Co., Ltd."
A variable information portion such as “* Kwh” that changes every time corresponding to * is included.

Therefore, the fixed information portion is stored in the dwelling unit side terminal 15 and the information signal transmitted from the center side terminal 13 is:
As shown in FIG. 2, an identification number 21 for identifying a fixed information part of a plurality of screens and an information signal 22 for a variable information part
And an information signal of 30 characters.

FIG. 3 shows an internal configuration of the dwelling unit side terminal 15, 31 is a demodulator for demodulating an information signal obtained from the line 14, 32 is a reception encoder for encoding the information signal, 33.
Is a reception control unit for decoding identification information; 34 is a ROM for storing fixed information portions;
Reference numeral 5 denotes a synthesizing unit for synthesizing signals obtained from the reception encoding unit 32 and the reception control unit 33; 36, a converting unit for converting character information output from the synthesizing unit 35 into dot information; and 37, a signal obtained from the converting unit 36. Is the television signal R
It is a television signal generator for converting into an F signal.

The operation of the above configuration will be described. The identification number 21 and the information signal 22 transmitted from the center side communication terminal 13 and supplied to the demodulator 31 via the line 14 are demodulated into a digital signal, and the identification signal 21 is transmitted to the reception control unit 33 and the variable information part. Are supplied to the reception encoding unit 32, respectively. In the reception control unit 33, for example, an information signal that is stored in the ROM 34 according to the identification number and that is a notification of a power outage construction, that is, a fixed information part, is extracted and supplied to the synthesizing unit 35.

On the other hand, the variable information portion encoded by the reception encoding unit 32 is also supplied to the synthesizing unit 35. In the synthesizing unit 35, the fixed information portion and the variable information portion are synthesized, the synthesized information as character information is converted into dot information in the converting unit 36, and the TV signal generating unit 37 converts the TV channels {1}, {2}, It is converted into an RF signal of an unused channel such as {3}. This RF signal is supplied to the television 17 and displayed on the screen as complete information.

When the customer operates the terminal, the voice generated by the voice synthesizer or the like is transmitted from the communication terminal on the center side, and the procedure to be operated is coded and presented by the voice. Operation time can be reduced.
