Automatic receiving terminal device and control method

The present invention relates to an automatic receiving terminal device and a control method thereof, and more specifically, to a basic administrative area and a specific place such as eup, nyeon, li, and dong by using a general telephone communication network (or "Cooking Line"). Regardless of the location, it is possible to remotely control the automatic receiving terminal device from anywhere in the country to perform general telephone broadcasting, radio broadcasting, automatic call broadcasting, disaster and civil defense siren control broadcasting according to voice announcement, and the result is data communication or voice The present invention relates to an automatic receiving terminal device and a control method thereof.

In agricultural and fishing villages in Korea, administrative notices, urgent matters, or civil defense siren broadcasts are made to village residents at village halls or municipalities such as municipal, county, eup, myeon, and dong offices. These local governments provide announcements to village residents through receiving terminals.

Then, the operation and problems of the conventional receiving terminal used so far will be described with reference to the accompanying drawings.

1 is a conceptual diagram illustrating the operation of a conventional receiving terminal.

In the figure, the first and second receiving terminals 30 and 40 are terminal devices installed at different places, respectively, and call subscribers by signals received through dedicated telephone lines (T / D to R / D). Or broadcast through the speakers throughout the town.

And the main control unit 20 is connected to the telephone station 10 and the dedicated telephone line (T / D ~ R / D) and is configured to control the operation of the receiving terminal (30, 40).

On the other hand, the operator controls the receiving terminal 1 through the main control device 20 connected to the telephone station 10 and the dedicated telephone line (T / D to R / D), and thus the basic administration of the town, town, village, town, village, village, etc. Announcement announcements will be made in areas and specific places.

By the way, in the conventional receiving terminal apparatus configured as described above, the user is configured to control broadcasting in whole or in groups by the main control apparatus 20 for dedicated telephone lines (T / D, R / D). If there is no main control device 20 in the area where the user wants to broadcast or there is a failure, there is a problem that cannot be used.

In addition, the conventional receiving terminal device has a problem that can be used only if a professional operator who can operate the main control device 20.
