Zusammenfassung: | 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 |
