Existing optical communication equipment can adopt 5V power supply power supply, and transmission rate is lower than the traffic rate of USB2.0, therefore utilizes USB interface can satisfy the various requirement of optical communication.But existing optical communication equipment still is in the starting stage, does not also have fixing interface protocol or industry standard, has therefore limited the range of business of optical communication output equipment.
The utility model content
The utility model execution mode technical problem to be solved is, a kind of optical communication emitter based on USB is provided, and can standard USB interface be applied to the optical communication output equipment, thereby strengthens the flexibility of optical communication output equipment range of application.
In order to solve the problems of the technologies described above, the utility model one embodiment provides a kind of optical communication emitter based on USB, and this emitter comprises USB interface, conversion chip, drive circuit and luminescence unit; Said USB interface is used to receive the USB differential signal; Said conversion chip is used for the USB differential signal that said USB interface receives is converted into the serial data signal of fixed frequency; Said drive circuit is used for according to said serial data signal driven for emitting lights unit luminous; Said luminescence unit is used for through visible light said serial data signal being sent.
Optional, said emitter also comprises the snoot that places said luminescence unit outside.
Optional, said snoot is processed by transparent material.
Optional, said luminescence unit is the LED lamp.
Optional, said USB interface is a standard USB interface.
In the technique scheme; USB Driving technique, conversion of signals technology and visible light communication technology are combined; When the USB interface of emitter receives the USB differential signal; This USB differential signal is transmitted to conversion chip, and conversion chip converts the USB differential signal serial data signal of fixed frequency into, and the driving circuit drives luminescence unit sends serial data signal through visible light.Because the USB interface of emitter can be connected with the USB interface of any intelligent terminal, thereby receive the data that intelligent terminal sends, thereby strengthen the flexibility of optical communication output equipment range of application.
