本発明は被監視地点に設けられている機械スイッチの状
態を監視する監視方式に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a monitoring method for monitoring the state of a mechanical switch provided at a monitored point.
（従来技術）
従来、被監視地点に設けた機械スイッチの状態は、リレ
ー回路によシ検出され、この検出結果は電気用ケーブル
を介して監視室地点に伝送されている。(Prior Art) Conventionally, the state of a mechanical switch provided at a monitored point is detected by a relay circuit, and the detection result is transmitted to a monitoring room point via an electrical cable.
このような従来方式では、リレー回路用電源設備が信頼
性向上のために他の電源設備とは別に被監視地点に必要
となシ、価格の上昇を招くという欠点がある。Such conventional systems have the disadvantage that power supply equipment for the relay circuit is required at the monitored point separately from other power supply equipment in order to improve reliability, leading to an increase in price.
（発明の目的）
本発明の目的は上述の欠点を除去し特別な電源設備を被
監視地点に設ける必要のないスイッチ情報伝送方式を提
供することにある。(Objective of the Invention) An object of the present invention is to provide a switch information transmission system that eliminates the above-mentioned drawbacks and does not require special power supply equipment to be installed at a monitored point.

気変換部３と、監視部４とから構成される。The figure shows one embodiment of a system using the present invention. This system consists of a transmitting optical fiber cable 5 that transmits an optical signal 9 from an optical signal transmitter 2 in a monitoring station 1 to a monitored station 7.
, a receiving optical fiber cable 6 whose one end is disposed on the optical path of the optical signal 9 emitted from one end of the optical fiber cable 5 and returns the optical signal 9 to the monitoring station 1; It consists of a mechanical switch 8 that cuts off the power, an optical/electrical converter 3, and a monitor 4.

Optical signal 9 transmitted from optical signal transmitter 2 in calyx monitoring station 1
is transmitted via the transmitting optical fiber cable 5 to the receiving optical fiber cable 6 in the monitored station 7 and then looped back to the monitoring station 1. On the other hand, when the switch is closed (or open), the movable part of the switch 8 cuts off the optical path between the transmitting optical fiber cable 5 and the receiving optical fiber cable 6, so no optical signal is sent back to the monitoring station 1. .
