Brief description of the drawings
Fig. 1 is the outdoor unit anti-theft device structural representation of satellite television receiving system of the present invention.
Embodiment
Illustrate present disclosure below in conjunction with specific embodiments.
As shown in figure 1, being the outdoor unit anti-theft device structural representation of satellite television receiving system of the present invention.
The outdoor unit anti-theft device of satellite television receiving system of the present invention, including：For recording during satellite receiving equipment work
The first timer long and that operating time can be converted into data signal output, first timer is arranged at satellite television and connect
The outdoor unit of receipts system；For receiving the data signal of first timer output and carrying out computations to export encryption
First encrypting module of signal, first encrypting module is arranged at the outdoor unit of satellite television receiving system；For recording
Satellite receiving equipment operating time and the second timer that operating time can be converted into data signal output, second timing
Device is arranged at the indoor unit of satellite television receiving system；Data signal and progress for receiving the second timer output
Computations are to export the second encrypting module of coded signal, and second encrypting module is arranged at satellite television receiving system
Indoor unit；For receive first encrypting module and second encrypting module output coded signal and be compared with
Determine whether the authentication module of output control signal, the authentication module is arranged at the outdoor unit of satellite television receiving system；
For receiving the control that the control signal of the authentication module output makes the outdoor unit normal work of satellite television receiving system
Module, the control module is arranged at the outdoor unit of satellite television receiving system.
Specifically, the control module is arranged in low noise block downconverter and to control low noise block downconverter（I.e.
Tuner）In integrated chip operation.
The outdoor unit anti-theft device of satellite television receiving system of the present invention is to realize that its is antitheft in following method
Function：
Step one：The outdoor unit of satellite television receiving system is operated and timing, the family of satellite television receiving system
Microwave signal is received during outer cell operation and intermediate-freuqncy signal is exported；
Step 2：The timing result that step one is obtained is encrypted calculating and obtains the first encryption data；
Step 3：The indoor unit of satellite television receiving system receives the outdoor unit output of satellite television receiving system
Intermediate-freuqncy signal be just operated and timing；
Step 4：The timing result that step 3 is obtained be encrypted calculating obtain the second encryption data, this step plus
Close algorithm is identical with step 2；
Step 5：The second encryption data that the first encryption data and step 4 obtained to step 2 is obtained is contrasted,
It is output control signal when comparing result is consistent, otherwise not output control signal；
Step 6：The control signal for receiving step 5 output controls the outdoor unit of satellite television receiving system to carry out
Work, otherwise makes the outdoor unit of satellite television receiving system be stopped.
The AES of computations includes but is not limited in above-mentioned steps two and step 4：
DES（Data EncryptionStandard, data encryption standards）AES,
DSA（Digital Signature Algorithm, Digital Signature Algorithm）AES,
AES（Advanced Encryption Standard, Advanced Encryption Standard）AES etc..
Because the work of indoor unit of the outdoor unit and satellite television receiving system of satellite television receiving system has
Synchronism, therefore the timing result that step one is obtained is the data signal of the first timer output and the meter of step 3 acquisition
When result be second timer output data signal it is identical, as long as ensureing in i.e. described second encrypting module of step 4
AES and step 2 are that the AES in first encrypting module is identical, and the first encryption data is first encryption
The coded signal and the second encryption data of module output are that the coded signal of the second encrypting module output also can be identical, step
Five i.e. the authentication module will output control signal, be operated the outdoor unit of satellite television receiving system.
After the outdoor unit of satellite television receiving system is stolen, due to the outdoor unit of satellite television receiving system
In the first timer timing result and the timing knot of the second timer of the indoor unit of new satellite television receiving system
It is really inconsistent, therefore by first encrypting module and the coded signal of second encrypting module output and differ,
Authentication module stops output control signal so that the outdoor unit of satellite television receiving system is stopped.
Specifically, because the tuner in the outdoor unit of satellite television receiving system usually contains one or several collection
Into chip, therefore can be integrated in above-mentioned integrated chip by authentication module and control module, connect so as to improve satellite television
The security of the outdoor unit anti-theft device of receipts system, while destroying the outdoor unit anti-theft device of satellite television receiving system
Also tuner can be destroyed so that the outdoor unit of satellite television receiving system can not integrally work.
Above content is made for the present invention in conjunction with specific embodiments describes in detail, it is impossible to assert that the present invention is specific real
Apply and be only limitted to these explanations.For those skilled in the art, before present inventive concept is not departed from
Put, some simple deduction or replace can also be made, the scope of protection of the invention should be all considered as belonging to.
