REMOTE TRANSMITTING DEVICE
Document Type and Number:
Japanese Patent JPH0630467
Kind Code:
A
Abstract:
PURPOSE: To improve a remote transmission device securing the continuity of the communication of all interruption devices at the rear of a failure line. CONSTITUTION: This transmission device is separated into different subsystems containing power sub-stations PSA, PSB and PSC to which communication areas ZA, ZB and ZC are automatically allocated in accordance with the priority code of MODEM, the level of a received signal and the opening/closing position of one of the interruption devices I1-I3. The boundary is formed by an open line switch in a regular operation state. The MODEM of communication means 14 and 27 change the boundaries of the communication areas ZA, ZB and ZC with the structure of a coupling circuit taking a first bypass state or second duplex coupling state in an urgent operation state after input to a power system.
