Description of drawings
Fig. 1 is that star-seeking controller forms schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
The invention provides a kind of auxiliary satellite-finding controller, as shown in Figure 1, this auxiliary satellite-finding controller comprises power supply, Radio Beacon, main control board, display screen, external sensor, power interface, radio frequency interface and signaling interface.
Wherein, power supply comprises built-in lithium battery and the power supply adaptor that is connected the power interface connection, and lithium battery is whole star-seeking controller power supply, and capacity is 2200mAh.
External sensor comprises GPS module and obliquity sensor, and the GPS module is used for obtaining local latitude and longitude information, and bearing accuracy is less than 10m less than 48s start-up time for maximum cold; Obliquity sensor is installed on the fixed position of elevation axis of antenna, is used for obtaining actual antenna pitching angle, and resolution is 0.01 °.
Radio Beacon links to each other with the tuner LNB of antenna by radio frequency interface, and radiofrequency signal is processed.Because every telstar all can be launched the signal that a frequency and amplitude are all fixed, be generally the beacon of C or Ku wave band, Radio Beacon is down-converted to the satellite beacon signals of this wave band carries out signal behind the L-band and processes, demodulate a ratio in the DC voltage (AGC) of level of RF signals power, the foundation of seeking star as antenna.The frequency acquisition bandwidth of the Radio Beacon that the present invention adopts is 300kHz, and capture time is less than or equal to 300ms.
Main control board links to each other with built-in lithium battery, display screen, Radio Beacon, power interface respectively, and receives GPS module and obliquity sensor data by signaling interface.Main control board is responsible for the management that discharges and recharges of battery, and runs application, the main realization: (1) Real-time Collection sensing data; (2) detecting the Radio Beacon data processes; (3) realize the mutual of man-machine interface; (4) carry out satellite theory to the calculating of star angle; (5) the guiding operator carries out star is operated.The AGC numerical value displayed value at interface has reflected the power of received signal.When the antenna locking satellite, the interface has information indicating and hummer prompting.
Display screen is used for the demonstration human-machine interactive information, has adopted 7 cun very color digital screens of high-resolution, and output resolution ratio is 800 * 480 pixels, LED-backlit.
The auxiliary satellite-finding controller need to cooperate manual satellite antenna to use together, and operation steps is as follows:
Step 1, antenna surface towards Due South to, be well placed antenna, the radio frequency interface of auxiliary satellite-finding controller is connected with the LNB of antenna;
Step 2, GPS putting position should be avoided being blocked; Be positioned on the elevation axis of antenna obliquity sensor also fixing.(antenna is determined the riding position of obliquity sensor first to star the time, design fixed form, and calibrates by on-screen menu).
The satellite that step 3, auxiliary satellite-finding controller are selected according to the user, the Auto-matching satellite parametric reduction, and the local latitude and longitude information that is obtained by GPS, automatically calculate current orientation to star, pitching, polar theory angle, the operator notices that view screen shows, the Inclination maneuver of antenna is arrived theoretical value, owing to the polarizing angle scale and the position angle scale that have possessed on the manual antenna through calibration, therefore the angle that the operator only needs manually its position is adjusted to theory calculating gets final product.After the position adjustment of three axles is complete, in current location, about azimuth direction 30 ° with interior slow rotation antenna, search of satellite signals, and notice that simultaneously information indicating on the screen and AGC magnitude of voltage change, when the semaphore lock pilot lamp of screen is lighted, expression antenna locking satellite-signal, but also be not the optimum position, this moment, the operator need to be by orientation angles, the luffing angle of fine setting antenna, so that the AGC value reaches maximum, finish that namely star is operated.
In sum, above is preferred embodiment of the present invention only, is not for limiting protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
