Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
With reference to figure 1, Fig. 1 is the schematic flow sheet of first embodiment of the invention.
As shown in figure 1, the drifting buoy communication control method based on big-dipper satellite of the present invention, including step：
Step S10, the current attitude information of buoy is determined based on the gyroscope, accelerometer and magnetometer being built in buoy；
In step slo, drifting buoy can send the collection information of corresponding period every preset time period and be stored in buoy
The secondary collection information that last time in internal memory is not transmitted is being ready for sending collection information and secondary is adopted to Beidou satellite system
Before collecting information, the current attitude information of buoy is determined based on the gyroscope, accelerometer and magnetometer being built in buoy；Its
In principle be to be located at based on the satellite with Big Dipper short message message function in the stationary orbit in equator overhead, China user
In the Northern Hemisphere, therefore antenna is towards can obtain more preferably satellite-signal during south.Gyroscope, accelerometer are built-in with buoy
And magnetometer, pass through these sensors, it may be determined that the attitude information of current buoy.The antenna that the attitude information includes buoy refers to
To can determine whether buoy antenna is towards south accordingly.
Step S20, judging the attitude information is belonged in the range of the default posture that communicates；
Step S30, if attitude information belongs to the posture scope that can communicate, collection information is sent to Beidou satellite system.
After execution of step S10, by acquired attitude information, i.e., antenna points to, if antenna is to south by west or Dong Jiao
The number of degrees.Compared with the default posture scope that communicates, it is default communicate posture scope for antenna to 10 degree of south by west with
And within 20 degree of scopes of 10 degree of south by east.If now antenna point to it is default can be in communication range（Such as 5 degree of south by west）,
Perform step S30.It is to belong to the posture scope that can communicate when confirming, then sends the information that collects before to big-dipper satellite system
System.The present embodiment improves the stability of gathered data transmission, avoided because wind direction, wave, ocean current compared to prior art
Influenceed etc. factor for the communication signal of buoy and big-dipper satellite.
