Abstract
The invention relates to an automatic satellite searching device of live broadcast satellite. The device comprises a microcontroller, a driver and a stepping motor, which are sequentially connected, wherein the microcontroller is capable of generating pulse sequence and is connected with a set top box of the satellite, the driver receives the pulse sequence generated by the microcontroller, the stepping motor is capable of switching electrical pulse signal into angular displacement or linear displacement, and the stepping motor is fixedly connected with a satellite receiving pot. The invention has the advantages of automatically adjusting the direction of the satellite receiving pot, and improving the installation efficiency of the satellite receiving pot.
Description
[technical field]
The present invention relates to a kind of communication equipment, relate in particular to a kind of automatic satellite searching device of live broadcast satellite.
[background technology]
Development along with radio and television broadcasting satellite, at present increasing user uses the direct broadcasting satellite set-top box to watch program, promptly receive satellite and receive the signal that pot transmits by set-top box, yet receiving pot for common user installation direct broadcasting satellite is the relatively thing of difficulty of part, because need when install receiving pot No. nine satellites of accurate in locating culminant star through dimension, under the prior art situation, the user need position by the direction of artificial adjustment satellite acceptance pot, as long as there is deviation just can not receive signal slightly, not only difficulty is big, and very not convenient.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of automatic satellite searching device of live broadcast satellite, can adjust the direction that satellite receives pot automatically, and then has improved the efficient that satellite receives pot is installed.
The present invention solves the problems of the technologies described above by the following technical programs: comprise successively connecting: one can produce the microcontroller of pulse train, and this micro-control controller is connected with satellite set top box; One is used to receive the driver of the pulse train that microcontroller produces; One can change electric impulse signal into the stepping motor of angular displacement or displacement of the lines, and this stepping motor receives pot with satellite and fixedlys connected.
Further, described micro-control controller is connected by Serial Port Line with satellite set top box.
Further, described stepping motor is fixedlyed connected by a support and satellite reception pot.
The beneficial effect of automatic satellite searching device of live broadcast satellite of the present invention is: can realize that satellite receives the pot direction and adjusts automation of operation, and improve the efficient that satellite receives pot is installed.
[description of drawings]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is an automatic satellite searching device of live broadcast satellite of the present invention schematic diagram when using.
[embodiment]
See also Fig. 1, automatic satellite searching device of live broadcast satellite 3 of the present invention comprises successively and to connect: one can produce the microcontroller 31 of pulse train, and this micro-control controller 31 is connected with satellite set top box 2; One is used to receive the driver 32 of the pulse train that microcontroller 31 produces; One can change electric impulse signal into the stepping motor 33 of angular displacement or displacement of the lines, and this stepping motor 33 receives pot 1 by a support 4 and satellite and fixedlys connected.In addition, because Serial Port Line convenient and reliable, be connected by Serial Port Line between micro-control controller 31 and the satellite set top box 2 among the present invention.
Wherein: stepping motor 33 is a kind of open loop control elements that electric impulse signal can be changed into angular displacement or displacement of the lines; Microcontroller 31 can produce the pulse train of distinct pulse widths, and microcontroller 31 comes the rotation of control step motor 33 by driver 32 and stop, thus indirect control satellite receive the rotation of pot 1 and stop; Driver 32 receives the pulse train that microcontroller produces, when importing a pulse signal by microcontroller 31 to driver 32, stepping motor 33 promptly rotates an orientation angle with regard to step angle of stepping, in addition, this driver 32 also provides and is suitable for the required power supply of stepping motor 33.
Operation principle of the present invention: satellite set top box 2 receives and detects satellite in real time and receives pot 1 signal that transmits, whether the orientation angle of judging satellite acceptance pot 1 by the power of detection signal is correct: if incorrect, satellite set top box 2 produces the pulse train of corresponding distinct pulse widths by Serial Port Line notice microcontroller 31, driver 32 received pulse signals, and driver 32 receives a pulse signal stepping motor 33 and just rotates corresponding orientation angle, and stepping motor 33 drives satellite reception pot 1 by support 4 and does corresponding rotation; If correct, satellite set top box 2 is sought star unit 3 by the Serial Port Line notice and is stopped operating, thereby the indirect satellite reception pot 1 that allows stops operating.
