Description of drawings
Fig. 1 is based on the schematic flow sheet of the signal of telecommunication processing method of optical communication in the embodiment of the invention.
The realization of the object of the invention, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Describe technical scheme of the present invention in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present invention intuitively.
With reference to shown in Figure 1, present embodiment provides a kind of signal of telecommunication processing method based on optical communication, and it mainly may further comprise the steps:
S10, the signal of telecommunication is modulated into carrier signal;
S20, described carrier signal is separated into two drives signals;
S30, drive the signals input by two different monochromatic sources of power switch circuit input with described two;
S40, described two monochromatic sources are alternately launched monochromatic light according to described driving signal.
In step S10, utilize frequency generator to produce a first-harmonic, by modulation circuit above-said current signal and first-harmonic are modulated again, form above-mentioned carrier signal.
In step S20, can utilize digital aberration split circuit that carrier signal is separated into two and drive signal, each drives signal and comprises information such as the flicker frequency of corresponding monochromatic source and switching time respectively, when corresponding monochromatic source receives this driving signal, just light or extinguish according to driving signal, thus luminous by predetermined frequency and time flicker.Numeral aberration split circuit is a kind of circuit that can isolate needed signal from carrier signal.
In step S30 and step S40, driving the above-mentioned driving signal of signal with two is input in the power switch circuit, and this power switch circuit monochromatic source different with two connects, power switch circuit drives signal with these two and is loaded into respectively on these two different monochromatic sources, these two monochromatic sources are controlled, thereby make these two monochromatic sources luminous according to predetermined frequency scintillation, form lightwave signal.When the signal of telecommunication changes, carrier signal also changes, after carrier signal changes, two that separate from carrier signal drive signal and also change, thereby the flicker frequency of two monochromatic sources of control also changes, therefore, the change of the signal of telecommunication can be directly change by lightwave signal realize, make modification and expansion before the signal transmission become very simple and convenient.
Normally, the signal of telecommunication is control signal and/or digital signal, before the signal of telecommunication is modulated, needs to carry out following step:
S5, to the above-said current signal processing of encoding.
Step S5 is used for the signal of telecommunication is encrypted, and perhaps makes it satisfy the call format of specific host-host protocol.
After carrier signal being separated into the driving signal, signal strength signal intensity decreases, and therefore, also need carry out following steps between step S20 and S30:
S25, drive signals with above-mentioned two and amplify.
Can amplify processing to above-mentioned driving signal by driving amplifier, the signal strength signal intensity after the processing is strengthened to some extent, can satisfy request signal transmission.
In addition, the monochromatic source of present embodiment adopts led light source, can launch and comparatively concentrate monochromatic light spectrum, certainly, also can adopt other light source, as fluorescent lamp etc.
Because led light source has unidirection luminous property, therefore, can evenly launch to various directions in order to make lightwave signal, present embodiment is further comprising the steps of:
S50, the light that utilizes astigmatic device that above-mentioned two monochromatic sources are sent are evenly dispersed.
In the practical application, astigmatic device can adopt the optics atomized cover, and this optics atomized cover is located at two monochromatic source outsides, just can realize the effect that light is evenly dispersed easily.
In sum, the present invention is converted to carrier signal with the signal of telecommunication earlier, again carrier signal is converted to two driving signals controlling two monochromatic source flickers, the recycling power switch circuit is controlled flicker frequency and the switching time of two monochromatic sources according to driving signal, thereby the lightwave signal of various different flicker frequencies is launched.Therefore, the lightwave signal that optical signal launcher of the present invention sends can be stored more information, also can effectively improve the signal safety of transmission.And, any signal of telecommunication can be become carrier signal by coding with modulation conversion, control monochromatic source again, the lightwave signal that will comprise this signal of telecommunication is launched, and has extraordinary compatibility and autgmentability.
