Site preparation describes.
The embodiment of the present invention provides a kind of antenna azimuth detection method, as shown in figure 1, this method can include：
Step 101, the angle of pitch and roll angle for determining according to the acceleration information and gyro data of collection antenna.
The method that the embodiment of the present invention is combined using simulated solar sensor and geomagnetic sensor realizes round-the-clock antenna
Azimuth is detected, and is detected the antenna azimuth of high accuracy (± 3 °) when having the sun with simulated solar sensor, is passed with earth magnetism
Sensor detects the antenna azimuth of low precision (± 10 °), if it exceeds setting scope, then produces azimuthal variation alarm, this hair
The executive agent for the antenna azimuth detection method that bright embodiment provides can be antenna azimuth angle detecting device, the antenna bearingt
The main hardware of angle detecting device can include high performance single-chip microcomputer, nine axle attitude transducers, global position system GPS mould
Block, simulated solar sensor, nine axle attitude transducers include：Three axle geomagnetic sensors, 3-axis acceleration sensor, three axis accelerometer
Instrument.
Specifically, antenna for base station has the angle of pitch, i.e. angle of declination, the desired value of roll angle is 0, still, in actual measurement
The value of middle roll angle can not possibly be 0, it is necessary to roll angle survey calculation to antenna for base station, in order to obtain accurate antenna for base station side
Parallactic angle, it is necessary to first determine the accurate angle of pitch and roll angle, by nine axle attitude transducer gathered datas in the embodiment of the present invention,
Specific collection 3-axis acceleration sensor and three-axis gyroscope data, by carrying out Combined Calculation, karr to the data of the collection
Graceful filtering can obtain ± 1 ° of angle of pitch α and roll angle γ.
Wherein, Kalman filtering (Kalman filtering) is a kind of utilizes linear system state equation, defeated by system
Enter output observation data, the algorithm of optimal estimation is carried out to system mode.Due to observation data include noise in system with
The influence of interference, so optimal estimation is also considered as filtering.

Big data calculate, it is desirable to error is at ± 5 °, no requirement of real time；It is insensitive to concrete numerical value for antenna attitude abnormality alarming,
There is requirement of real time.
Step 102, when detecting sunray, according to the sun sensor data of collection determine sunray relative to
The incidence angle of the antenna.
Specifically, antenna azimuth angle detecting device obtains the optical signal shined upon, the optical signal is converted into electric current
Value, incidence angle of the sunray relative to antenna is determined according to the current value.
Simulated solar sensor is also referred to as cosine detector more using light-sensitive device as light-sensitive element, when sun signal shines
Penetrate when thereon, the intensity of its output signal electric current is relevant with solar incident angle, therefore can be sentenced using the size of output current
The incident angle of disconnected sunshine.Analog sun sensor has the characteristics that small volume, low in energy consumption, simple in construction.
It is exemplary, as shown in Fig. 2 the principle of simulated solar sensor, simulated solar sensor bottom be four-quadrant too

Spend for H controlling the size for the solar facula for projecting cell piece.When sunray is incident to cell piece along a certain angle,
Each quadrant produces different current value I1, I2, I3 and I4 respectively.From the photovoltaic property of solar battery sheet, cell piece
Photogenerated current meets cosine characteristic, i.e.,：
I (θ)=I0cosθ·S
Wherein, in above formula, I0Unit area current caused by simulated solar sensor is impinged perpendicularly on for the sun, θ is
Solar incident angle, S are exposed area.Therefore, the photogenerated current of four-quadrant cell piece can be expressed as：
I1=I0cosθ·(L+dx)(L+dy)
I2=I0cosθ·(L-dx)(L+dy)
I3=I0cosθ·(L-dx)(L-dy)
I4=I0cosθ·(L+dx)(L-dy)
Wherein, L is the half of the light shield perforate length of side, and (dx, dy) is the centre coordinate of solar facula.
By above-mentioned calculating I1、I2、I3And I4Equation can obtain the calculation formula of centre coordinate and be：
