Description
Technical field
It is specifically a kind of unidirectional biography based on LIFI light the present invention relates to a kind of one-way transmission apparatus
Defeated device, belongs to communication technical field.
Background technology
Network service has become the basic tool of information interchange between world's all trades and professions, but existing communication network
And communication equipment is all to be all based on traditional communication protocol greatly to complete, and it is built upon traditional physics
On the basis of link, communication security cannot be effectively ensured, it is impossible to meet the guarantor such as army, state security department
The communication requirement of close unit.
On January 11st, 2013, Chinese invention patent application CN103067405A discloses a kind of inter-network
Safe transmission method and its device, it is by the data after data processor disposal data information needs transmission
Two-dimension code pattern output to display screen is converted into, by the way that probe is every sky scanning two-dimension code pattern and reads character
Go here and there, be transferred to another separate network after data processor is changed.But by Quick Response Code single transmission
Information capacity is limited, and transmission speed is relatively slow, it is impossible to realize that data inter-network is quickly transmitted；In addition the device
Complex structure, the famous physicist HeraldHaas of 2011 Nian8Yue Britain have developed a kind of brand-new nothing
Line data transmission technology, the technology is referred to as Light Fidelity, abbreviation Li-fi, is that one kind utilizes light
The technology of the optical transport data that source sends, its pass through LED light source it is quick open, light switching, it is Huo Zheqiang, weak
Switching, realizes binary coding to information and transmission, the present invention will using Li-fi technologies realize unidirectionally,
Quickly, safety-oriented data transfer.
The content of the invention
The technical problems to be solved by the invention are to overcome drawbacks described above, there is provided a kind of transmission capacity is big, biography
The one-way transmission apparatus based on LIFI light that defeated speed is fast, transmitting procedure is safe.
In order to solve the above-mentioned technical problem, the one-way transmission apparatus based on LIFI light that the present invention is provided,
