| description | To provide a light monitoring control system having redundancy while suppressing increase in the number of laid cables.SOLUTION: A light monitoring control system includes: a power line communication unit 100 that is connected to a light emitter group composed of a plurality of light emitters LE and slave stations 110, the slave stations 110 connected to the light emitters LE, and performs communication by superposing information for light monitoring control on current for lighting up the light emitters LE; a controller 20 for processing the information for light monitoring control; and a master station 230 that is provided between the power line communication unit 100 and the controller 20 and communicates the information for light monitoring control via a communication path 210. The information for light monitoring control includes control information for controlling lighting of the light emitters LE and a burnout detection signal for detecting burnout of the light emitters LE. The plurality of controllers 20 are provided. The plurality of master stations 230 are provided correspondingly to one power line communication unit 100. The communication path 210 is configured to be redundant so that which of the plurality of controllers 20 are taken as main one and sub one is switchable and which of the plurality of master stations 230 are taken as main one and sub one is switchable.SELECTED DRAWING: Figure 1
【課題】ケーブルの敷設数の増大を抑えつつ、冗長性を持つ灯火監視制御システムを提供する。【解決手段】灯器ＬＥに接続された子局１１０、複数の灯器ＬＥ及び子局１１０からなる灯器群に接続され、灯器ＬＥの点灯のための電流に灯火監視制御のための情報を重畳して通信する電力線通信部１００、灯火監視制御のための情報を処理するコントローラ２０、電力線通信部１００とコントローラ２０の間に設けられ、灯火監視制御のための情報を通信経路２１０を介して通信する親局２３０を有し、灯火監視制御のための情報は、灯器ＬＥの点灯を制御する制御情報と灯器ＬＥの断芯を検知する断芯検知信号を含み、コントローラ２０は複数設けられ、親局２３０は、一つの電力線通信部１００に対して複数設けられ、複数のコントローラ２０のいずれをメインとするか、サブとするかを切り替え可能となるように、且つ、複数の親局２３０のいずれをメインとするか、サブとするかを切り替え可能となるように、通信経路２１０が冗長化されている。【選択図】図１ |
