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
数の子局の停電信号を受信できるようにした親局装置を
提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a master station device that eliminates the above-mentioned drawbacks and allows one receiver to receive power outage signals from a plurality of slave stations.

器で受信する構成をとっている。In order to achieve the above object, the present invention includes a line switching unit that operates independently of the telemeter data reception processing and one receiver that performs reception processing of the output signal from the switching unit in the master station, and a plurality of The power outage information of the slave station sent from the slave station is received by one receiver while sequentially switching lines by the switching section.
以下、図面を参照して本発明の一実施例を説明する。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

号発信器である。The reception operation of pre-meter data is the same as that of the conventional device, and the telemeter data transmitting units A1 to An of the slave stations II to Kn also send the sent data to the next line P,
-□ is taken in one step, and the telemeter data receiving section 6 receives and processes the data. 2 is a switching control section that controls the switching section l. On the other hand, in order to receive and create a power outage signal, unlike the conventional device, the lines 11 to 11 are connected to another line switching unit 3 which operates independently of the switching unit 1, and the switching unit 3 sequentially connects the lines 11 to 11 to 11, . , eo, the receiver 5 detects and receives the power outage signal. Reference numeral 4 designates a switching control unit for controlling the switching unit 3, B, ~B, and ~Kn power outage and signal transmitters for slave stations.
本発明は以上説明したような構成および方法によって、
複数の子局の停電情報を1つの受信器で受信する事が可
能となる利点がある。The present invention has the configuration and method as explained above,
There is an advantage that power outage information of multiple slave stations can be received by one receiver.
