[description of drawings]
Fig. 1 is a block diagram of the present invention.
[embodiment]
As shown in Figure 1, the present invention is the satellite-signal automatic tracking system, comprises horizontal motor 1, vertically motor 2, the one H bridge drive circuit 3, the 2nd H bridge drive circuit 4, the first photoelectric encoders 5, the second photoelectric encoders 6, main control chip 7, satellite-signal intensity input circuit 8, memory 9, input button 10.
A described H bridge drive circuit 3, the two H bridge drive circuits 4, the first photoelectric encoders 5, the second photoelectric encoders 6, satellite-signal intensity input circuit 8, memory 9, input button 10 is connected with this main control chip 7 respectively.
Described main control chip 7 is surveyed the rotational angle of vertical motor 2 by the rotational angle of first photoelectric encoder, 5 detection level motors 1 by examining second photoelectric encoder 6; Main control chip 7 detects the power of satellite-signal according to satellite-signal intensity input circuit 8, drive 1 rotating of a H bridge drive circuit 3 controlling level motors, drive vertical motor 2 rotatings of the 2nd H bridge drive circuit 4 controls, realize adjusting the angle of satellite receiver.
On main control chip 7, be connected with the indicator light circuit 12 that is used to show the satellite-signal power by PWM modulation circuit 11.Main control chip 7 is adjusted the size that PWM modulation circuit 11 is imported the PWM pulsewidths according to the power of satellite-signal, regulates the brightness of the indicator light on the indicator light circuit 12 with this, and bright more expression satellite-signal is strong more.Also be provided with power supply indicator on the indicator light circuit 12.
It is the chip of 78F511 that described main control chip 7 adopts model.A described H bridge drive circuit 3 includes four metal-oxide-semiconductors that connect into the H shape.Described the 2nd H bridge drive circuit 4 also includes four metal-oxide-semiconductors that connect into the H shape.Described input button is 6, is respectively the mains switch button, automatic keying, upper and lower, left and right manual fine-tuning button.
Operation principle of the present invention is as follows:
Power supply inserts, and power supply indicator is bright; Press automatic keying, then turn round by seeking the platform mode automatically; Can the manual adjustments direction by upper and lower, left and right manual fine-tuning button;
Automatically it is as follows to seek the platform mode:
(1) power on after, main control chip 7 control satellite-signal intensity input circuits 8 detect the power of satellite-signals; And write down by the current angle A of first photoelectric encoder, 5 detection level motors 1 and by main control chip 7, the horizontal motor 1 of main control chip driving clockwise rotates then, and revolution was once then being write down the power value of the satellite-signal of corresponding angle in the rotation process;
The strong and weak value of the signal of writing down when (2) turning to a certain angle＞60% as horizontal motor 1, then main control chip 7 stops by a H bridge drive circuit controlling level motor 1 at once, and remembers current angle B;
(3) main control chip 7 drives upwards swing of motor vertical 2 by the 2nd H bridge drive circuit, increases as the strong and weak value of signal and then continues to go up pendulum, puts when the strong and weak value of signal reduces on always and stops; As above pendulum finds promptly that at the beginning the strong and weak value of signal reduces, and the bottom in the other direction then increases as the strong and weak value of signal and then to continue the bottom, stops when signal power value reduces;
(4) as the strong and weak value of the signal of main control chip in horizontal motor 1 rotation process 7 record do not have＞60%, when then horizontal motor 1 turns to (A+359 degree), revolution in the other direction automatically is turned back to the peaked position C of signal power; Repeated for the 3rd step in the C position.
(5) during inactive state, be lower than 50% in case main control chip 7 is found the strong and weak values of signals, then the horizontal motor of driving immediately clockwise rotates, and increases as finding the strong and weak value of signal, then continues to clockwise rotate, until position D stops during the strong and weak value minimizing of signal; In the D position, vertical motor swings up and down described in the repetition 3;
(6) clockwise rotate as horizontal motor 1 and find promptly that at the beginning the strong and weak value of signal reduces, then oppositely rotate counterclockwise immediately, increase, then continue to rotate counterclockwise, until position E stops during the strong and weak value minimizing of signal as finding the strong and weak value of signal; In the E position, repeat swinging up and down of vertical motor described in 3;
(7) all find counterclockwise clockwise that as horizontal motor 1 the strong and weak value of signal reduces, repeat immediately in the C position then that vertical motor swings up and down described in 3.
