Intelligent lighting control system and control method thereof

Abstract

The invention relates to an intelligent light control system which comprises a mechanical switch, light controllers and a light load which are connected in sequence, wherein each light controller comprises a power switching unit, a light load driving circuit, a central processor connected with the light load driving circuit, and a wireless communication circuit connected with the central processor, each light controller further comprises a charging capacitor, a switch signal detection unit and a gateway, and the gateways detect the on and off state of a mains supply connected to the mechanical switch and send network connection signals and transient outage identification signals to the light controllers. The invention further provides a light control method. According to the intelligent light control system and method, the light controllers are charged through the charging capacitors so that normal operation of the light controllers is maintained and light state records can be prevented from disappearing after outage; meanwhile, the gateways used for judging transient outage are connected to the network and can send signals to the light controllers, and then the state, changed by mistake due to transient outage, of the light load is recovered.

Description

technical field [0001] The invention belongs to the field of information automation, and in particular relates to a control system and a control method for changing the state of a light by means of a short power-off of a mechanical switch. Background technique [0002] In today's intelligent lighting renovation project, there are the following three schemes that can be completed without changing the circuit at all: [0003] 1. Replace the original wall mechanical switch with a smart switch. Since most traditional switches do not need to be connected to the neutral wire, the smart switch must have a single live wire working characteristic. Although related products have appeared on the market, most of them only have one-way communication function (that is, the switch only has the function of wireless reception, and the switch can only be controlled by the remote control, and the interconnection and scene control between switches cannot be performed) , the stability is also u...

AI Technical Summary

Problems solved by technology

The wireless control panel is generally powered by an internal battery, so the biggest disadvantage is that the battery needs to be replaced after a period of use, which brings inconvenience to the user

[0006] At the same time, in the above three situations, a second-level power outage occurs in an unstable situation. Since the relay is always in the pull-in state before the power is restored, the power consumption is large, and the power of the lighting controller will quickly drop to stop working, and the lighting load will also drop. will therefore go out, causing a change in the state of the light
