Abstract
The invention discloses a digital communication method based on visible light, and the method employs a visible light source for wireless communication. The method specifically comprises the steps: controlling the ON duration of the visible light for representing the starting position of data transmission; controlling the OFF and ON durations of the visible light for representing to-be-transmitted digits '1' and '0'; and controlling the OFF duration of the visible light for representing the ending position of data transmission. The method just modifies the control program of an LED illuminating lamp or an LED indication lamp of a controller under the condition that the structure of an original product is not modified, the functions of the original product are not affected and the cost is not increased. The method outputs the product specification and working state information of the local controller through taking digital coding visible light as a medium and employing the LED illuminating lamp or the LED indication lamp. The method achieves the lossless testing of the controller, reduces the testing cost, and improves the production efficiency. The method can be widely used in controllers of various electric tools.
Description
Technical field
The present invention relates to the digital communication method in a kind of wireless communication field, refer more particularly to a kind of digital communication method based on visible ray.
Background technology
As everyone knows, most of electric tool adopts light-emitting diode (LED) as indicator light or illuminating lamp all usually.The controller of this type electric tool, domestic and international technology is universal and ripe, be subject to cost and the spatial limitation of product, this type electric tool does not all set up separately external communication interface, after Product Assembly, obtain the information such as the category of product circuit, version if want, then must disassemble checking to product, working strength greatly and easily cause damage of product.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of digital communication method based on visible ray utilizing visible light source to carry out radio communication.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of digital communication method based on visible ray, its concrete grammar is: the start bit being represented transfer of data by the light duration controlling visible ray, represented " 1 " or " 0 " that will transmit data by the duration of go out light and the light that control visible ray, by control visible ray go out light time the long stop bits representing transfer of data, thus realize the digital communication of transmitting-receiving two-end.
As a kind of preferred version, described based in the digital communication method of visible ray, represent the light duration of the visible ray of " 1 " or " 0 " in described transmission data and represent that the light duration of start bit is unequal, represent in described transmission data the visible ray of " 1 " or " 0 " go out light time long with represent stop bits go out light time long unequal.
As a kind of preferred version, described based in the digital communication method of visible ray, described visible ray derives from indicator light or illuminating lamp.
The invention has the beneficial effects as follows: present invention achieves not revising original product structure, do not affect original product function and do not increase cost prerequisite under, the only LED illumination lamp of change control device or LED light control program, by LED illumination lamp or LED light, with digitally coded visible ray for medium, the information such as the product specification of output local controller and operating state.Non-destructive testing is achieved to controller, reduces testing cost, improve production efficiency.
Embodiment
The specific embodiments of a kind of digital communication method based on visible ray of the present invention is described below in detail:
A kind of digital communication method based on visible ray of the present invention, concrete grammar is: by control the visible ray sent as the visible light source of indicator light or illuminating lamp light and go out light time long the start bit distinguished in communication process, data segment and stop bits are modulated to visible ray, thus realize the digital communication of transmitting-receiving two-end; In the present embodiment, the start bit of transfer of data is represented by the light duration controlling visible ray, represented " 1 " or " 0 " that will transmit data by the duration of go out light and the light that control visible ray, by control visible ray go out light time the long stop bits representing transfer of data, and, represent the light duration of the visible ray of " 1 " or " 0 " in described transmission data and represent that the light duration of start bit is unequal, represent in described transmission data the visible ray of " 1 " or " 0 " go out light time long with represent stop bits go out light time long unequal.
During practical application, can 300 microsecond lights representative transmission start bits, go out light, 200 microsecond lights of 200 microseconds represent digital " 0 ", and go out light, 400 microsecond lights of 200 microseconds represents digital " 1 ", represent end of transmission position with the 300 microseconds light that goes out.
In sum, be only preferred embodiment of the present invention, not be used for limiting scope of the invention process, all equalizations done according to shape, structure, feature and the spirit described in the claims in the present invention scope change and modify, and all should be included in right of the present invention.
Claims (3)
1. the digital communication method based on visible ray, its concrete grammar is: the start bit being represented transfer of data by the light duration controlling visible ray, represented " 1 " or " 0 " that will transmit data by the duration of go out light and the light that control visible ray, by control visible ray go out light time the long stop bits representing transfer of data, thus realize the digital communication of transmitting-receiving two-end.
2. as claimed in claim 1 based on the digital communication method of visible ray, it is characterized in that: represent the light duration of the visible ray of " 1 " or " 0 " in described transmission data and represent that the light duration of start bit is unequal, represent in described transmission data the visible ray of " 1 " or " 0 " go out light time long with represent stop bits go out light time long unequal.
3., as claimed in claim 1 or 2 based on the digital communication method of visible ray, it is characterized in that: described visible ray derives from indicator light or illuminating lamp.
