Remote intelligent dimming system and intelligent dimming method thereof

Abstract

The invention discloses a remote intelligent dimming system. The system comprises a field controller, a connecting circuit, a power supply, a cloud server and a plurality of controlled illuminating lamps. The power supply, the field controller and the controlled illuminating lamps are all connected with the connecting circuit, the field controller is in communication connection with the cloud server through a public communication network, and the field controller comprises a carrier amplification coupling unit, a carrier modulation unit and a dimming initiating unit. Each controlled illuminating lamp comprises a carrier demodulation unit, a light source driving unit and a light source. The system has the advantage of long-distance dimming signal transmission, cancelling a communication cable, reducing the cost, and being simpler and more convenient in installation and debugging and excellent and reliable in performance.

Description

technical field [0001] The invention relates to a dimming system, in particular to a remote intelligent dimming system and an intelligent dimming method thereof. Background technique [0002] In the intelligent lighting system, in addition to the control of turning on and off the lights, it also involves the adjustment of the brightness (luminous flux) of the controlled lighting. At present, the common dimming systems include 0 / 1-10V dimming, DALI dimming Lighting, KNX dimming, etc., but these dimming systems are not completely suitable for occasions such as road lighting, bridge lighting and garden lighting, because in these occasions, the controlled lighting lamps are scattered and the distance between the on-site controller and the lamps And the distance between lamps and lamps is relatively long. It is difficult for these dimming systems to control all the controlled lighting lamps. Although a wireless remote dimming system can be used, this dimming system has high cost,...

[0002] In the intelligent lighting system, in addition to the control of turning on and off the lights, it also involves the adjustment of the brightness (luminous flux) of the controlled lighting. At present, the common dimming systems include 0 / 1-10V dimming, DALI dimming Lighting, KNX dimming, etc., but these dimming systems are not completely suitable for occasions such as road lighting, bridge lighting and garden lighting, because in these occasions, the controlled lighting lamps are scattered and the distance between the on-site controller and the lamps And the distance between lamps and lamps is relatively long. It is difficult for these dimming systems to control all the controlled lighting lamps. Although a wireless remote dimming system can be used, this dimming system has high cost, poor real-time performance and low reliability. Therefore, , it is necessary to develop a remote dimming system with low cost, easy installation and debugging, and excellent and reliable performance
