Abstract

PURPOSE:To switch successively plural outputs of service interruption by a circuit and to receive the service interruption information with a receiver, by providing a circuit switching part which works independently of the reception processing of telemeter data and said receiver within a master station. CONSTITUTION:Plural slave stations K1-Kn are connected to a master station M by circuits l1-ln. The data sent from telemeter transmitting parts A1-An of slave stations K1-Kn are received with successive switching performed by circuits A1-An at a circuit switching part 1 and processed at a telemeter data receiving part 6. When a service interruption is detected at a service interruption signal receiver 5, circuit switch control parts 2 and 4 are actuated by the service interruption detecting signal. Then the service interruption and reception are processed while the circuits l1-ln are switched at a circuit switching part 3. The outputs of service interruption information of stations K1-Kn are successively switched, and the service interruption information is received by a receiver 5 and processed.

なる等の欠点があった。Conventionally, this type of remote monitoring device has used a method as shown in FIG. 1 to transmit power outage information of a slave station to the battle station. In other words, when a power outage occurs, a transmitter that can output a power outage signal consisting of a frequency different from the variable frequency of the telemeter data for a certain period of time is installed in the slave station, and when a power outage occurs, the power outage signal is sent to the master station via a line, and the master station Now, this power outage signal is received by a receiver installed in each slave station (・). Therefore, this method requires the same number of receivers as the number of slave stations to be installed in the master station, so that the As the number of slave stations increases, the number of receivers increases and the number of receivers increases, making the master station equipment larger and more expensive. .

本発明の目的は、上記欠点を除去し、１つの受信器で複
