One of the present embodiment has particular application as, and in use, specific embodiment is as follows by the present invention: embodiment one,
Debugging
A pair of of antenna carries out mutual data communication, in internal existing parameter, the relative position use of other side is positioned,
Interference compensation laser 202 carries out Laser emission.When both sides receive the laser of other side, behavior controller 9 is according to unofficial biography
Optical information received by sensor array 302 carries out parameter calculating, and sends fine tuning control letter to automatic tracing orientation system 403
Number, device is finely adjusted.When as carried out data transmission in Figure 11 to satellite, since distance is remote, under to a certain degree, laser
Hot spot scatter.And since the speed of service of satellite is fast, in debugging and normal use, very small precision is all
It will cause very big offset.Therefore an individual behavior controller 9 is used, it is required for carrying out control to all moving parts
's.Incidence is transmitted to after the photosensitive sensor signal conversion unit 903 of behavior controller 9 converts optical signals into binary data
Light source parameters computing unit 904 is calculated, and obtains a series of light data parameter, and corresponding parameter is sent to laser function
Rate control unit 905 is used to control laser power, light sensor arrays angle and lens adjustment automatic control unit 901 and is used to
Control inner sensor array 301 angle and light modulation lens 404 distance come make spot size just, automatic tracing orientation system
Parameter compensation control parameter output 907 is used to finely tune automatic tracing orientation system 403.Optical parameter input and output are controlled simultaneously single
Member 809 carries out communicating with each other for optical parameter, compares to the parameter to data laser 201, links up and completes to adjust for the first time
Examination is completed.
Embodiment two, data transmission
After the completion of first time debugs, so that it may carry out the transmission of data and debugging.Here by mutual laser parameter
It is arranged, starts to debug data laser 201.After mutually sending several debugging light, so that it may determine data
The working condition of laser 201, then carries out data transmission.Transmission principle is based on Chinese invention patent publication number
A kind of high system Transmission system of the number of electromagnetic wave simulation disclosed in CN201510958059.6 and its transmission method, but control principle
Based on HF switch 1001.Master controller 8 realizes the high frequency on-off of laser by control HF switch 1001, so that data
Laser 201 is quickly glistened, to transmit data.After the principle using polarised light, two sets of complete phases can be used
Laser group and corresponding photosensitive sensor with spectrum.Pass through orthogonal polarized lenses 304, so that it may so that inner sensor
Sensor on array 301 receives the laser of different polarization angle, will not interfere.Secondary tune after the completion of data transmission several times
Examination is completed, so that it may be carried out data and formally be transmitted.
Embodiment three, error correction
Atmospheric interference is had in laser data transmission progress or other objects are blocked, to cause optical signal power
Weaken.At this moment by being compared to mutual positioning, 202 power parameter of interference compensation laser, so that it may obtain interference journey
Degree, and it is corresponding to the progress power regulation of data laser 201.By power amplification circuit 1002 to data laser 201
Power amplification is carried out, so that data signal strength keeps stablizing when receiving.And when positioning, 202 power of interference compensation laser
When reducing to a certain extent, so that it may stop data transmission.Behavior controller 9 is by outer sensor array 302 to all simultaneously
Incident laser is counted.With the emitting times of statistical data laser 201.When the unit set in transport protocol
When interior data laser firing signals number is not identical, then representing in this unit time, data transmission is wrong, therefore, meeting
Optical signal quantity error code is sent to master controller 8.And master controller 8 can also believe data light by inner sensor array 301
It number is counted, as long as soon as the two counting has when the error occurs, the mistake of data transmission is represented, master controller 8 can basis
The system data prestored sends retransmission data code to other side.After receiving code, other side's master controller 8 can be from transmission light number
Emitted again according to the data transferred inside storage unit 805 in this unit time.
Example IV send data again
After the data emitted again are sent, so that it may be incorporated into data queue again, pass through binary data converting unit
801 are converted into outbound data, by data input and output 808, are exported.And inputting process then is data by data input and output
Enter binary data converting unit 801 after 808 inputs to be converted into sending optical data storage unit after simulating high binary data
805 store etc. it is to be launched.Send optical data storage unit 805 indeed through control high frequency and power controller 10 into
Row data laser controlling.Data transmitting is carried out by the data laser 201 that behavior controller 9 controls power.Due to data
Signal is possible to mistake occur, therefore the data for sending storage in optical data storage unit 805 can store certain time again, to protect
Card can be sent when needing to send again.
