Abstract
The invention relates to an optical information field module for an indoor household electrical appliance wireless optical communication system which is mentioned in a patent of the author applied in 2014, namely, an optical information field-based indoor household appliance signal wireless optical communication system. The optical information field module of the invention is composed of an information fusion circuit, an encoding circuit, a modulation circuit, a driving circuit, an LED, an optical transmitting system and the like. Three kinds of signals such as home video signals, audio signals and control signals are fused; fused signals are processed by the encoding circuit; modulated signals can be formed through the modulation circuit; the modulated signals are driven through the driving circuit, and thereafter switch on the indoor LED; light emitted by the LED is projected into a house through the optical transmitting system; and an indoor optical information field can be formed through the diffraction and diffuse reflection of the light. Based on the establishment of the optical information field, various kinds of weak electric signals are dispersed to various corners of the house, and the household electrical appliances can receive required signals at any position, so that the optical transmission of the weak electric signals can be realized, and the base of indoor household electrical appliance signal wireless optical communication can be formed.

Summary of the invention
In view of this, it is an object of the invention to provide one and (see this Shen for indoor electric appliance signal radio optical communication system
Another patent application " indoor electric appliance signal radio optical communication system based on optical information field " asked someone 2014) optical information
Field module.The purpose of the present invention, realizes by following technical solution:
The video signal registered one's residence, audio signal, three kinds of electrical signals of control signal through signal fused circuit, are carried out signal and melt
Close, after encoded processing of circuit, form modulated signal by modulation circuit, after modulated signal is driven by drive circuit,
Light the light that indoor LED, LED send, project indoor by optical emission system, by the diffuse-reflectance forming chamber of light
Optical information field；Optical information demodulation terminal (being called for short: optical transmitter and receiver) is coordinated (to see the applicant's another patent application in 2014
" indoor electric appliance signal radio optical communication system based on optical information field ") realize the Based Intelligent Control to household electrical appliances.
Described LED, it is characterised in that: it is designed based on two kinds of LED of visible ray and infrared light, infrared LED and visible
Lighting during light LED difference, when i.e. opening visible LED, infrared light LED closes；When opening infrared light LED, it is seen that light
LED closes.
It is characterized in that: optical information field contains video signal, audio signal, the modulation of three kinds of electrical signals of control signal
Information.
The present invention compared with prior art has the advantage that
