Description

The Smart Home illuminator

Technical field

The present invention relates to power line communication technology, network, microcontroller combines, namely be that physical media is linked to be a network to microcontroller and LED light fixture, the PC that can accept pwm signal with the power line, just can carry out Long-distance Control to the brightness of every lighting by PC, especially a kind of Smart Home illuminator.

Background technology

Power carrier communication refers to utilize plan or digital signal to advance existing power line, by the technology of carrier system with the line high-speed transfer.Maximum characteristics are not need to set up again network, as long as live wire just can carry out the data transmission.

At present main communication mode has power line carrier, radio communication, telephone wire, optical fiber, cable etc., and Reliability of Wireless Communication is poor, is not suitable for using in adverse circumstances, and especially being not suitable for Utilities Electric Co. is the metering method of unit with the transformer; Optical fiber cost height, installation inconvenience, especially under electrical network and communication network can't realize merging at present, Utilities Electric Co. can not repave optical cable; Cable needs all ammeters are connected with lead with telephone wire, and the construction cost height is difficult to safeguard, is not suitable for using on a large scale.

Summary of the invention

The object of the present invention is to provide a kind of Smart Home illuminator, this system namely is that physical media is linked to be a network to microcontroller and LED light fixture, the PC that can accept pwm signal with the power line, just can carry out Long-distance Control to the brightness of every lighting by PC.

Technical scheme of the present invention is: a kind of Smart Home illuminator, this system comprise master controller and subordinate machine system two parts; Master controller comprises carrier communication module, RS-232 modular converter, computer RS-232 interface, and master controller can external computer, and the communication carrier module is received on the AC220V; Signal pins on the communication carrier module links to each other with signal pins on the RS-232 modular converter; Segment signal output on the RS-232 modular converter is connected with computer by RS-232 interface; Subordinate machine system comprises communication carrier module, single chip circuit, receives the Switching Power Supply light source of pwm signal outward, and single chip circuit comprises single-chip microcomputer, infrared induction module, crystal oscillating circuit, and the communication carrier module is linked on the AC220V; Signal pins on the communication carrier module links to each other with single-chip microcomputer in the single chip circuit; Pwm signal output pin on the single-chip microcomputer links to each other with the holding wire on the Switching Power Supply; The input of Switching Power Supply connects AC220V, and the output of Switching Power Supply is connected with light source;

One of master controller gets final product, and extension set can expand to a lot of platforms, and the address on each extension set in the single-chip microcomputer is different, is used for distinguishing extension set, and the extension set sequence number is determined by single-chip microcomputer that mainly if the self-identification serial number of single-chip microcomputer is 1, then this extension set then is extension set first; If the self-identification serial number of single-chip microcomputer is 2, then this extension set is extension set second, and on all communication carrier modules, the 220V of access is same group.

The invention has the advantages that: power line carrier communication is that carrier transmits the network information with existing power line, therefore need infrastructure investment and regular maintenance expense hardly, and because power line is ubiquitous in the modern life, not influenced by wiring puzzlement and wireless environment, realize covering on a large scale.Utilize the Alternating Current Power Supply line as communication medium, need not to lay the private communication line; Wire communication is not subjected to weather and the influence of topography, has guaranteed system reliability; By software programming, can carry out subregion to lighting, divide circuit, grouping management; Also can carry out visualized operation; Infrared induction cuts down the consumption of energy, and energy-saving and emission-reduction prolong lamp life; Intellectuality, by computer, the user can regulate illuminating effect arbitrarily.
