Title:
灯火監視制御システム
Document Type and Number:
Japanese Patent JP7110084
Kind Code:
B2
Abstract:
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
