KR950023162A - Real-time situation monitoring device using subscriber line - Google Patents

Abstract

The present invention provides an unmanned remote meter reading system by installing a dedicated line securing device using a common subscriber channel in a radio transmission and reception equipment of islands without data dedicated lines, thereby performing centralized operation maintenance work of communication equipment without data dedicated lines. It's about technology that makes it possible.

The present invention is connected to the local measuring equipment (5) for collecting information on the local equipment (3) side installed in the island region, and connected to the mother country equipment (2), the domestic equipment provided from the remote measuring means (5) It is characterized in that it comprises a main control means (4) for controlling the secured as a dedicated line through the general channel occupancy control in order to receive and analyze the received information and perform the concentrated operation maintenance.
