Description
Technical field
The invention belongs to wireless communication technology field.The white frequency spectrum detection side of specifically related to a kind of TV based on Internet of Things
Method.
Background technology
The existing technology for being directed to M2M communication, mainly mobile operator technology.Mobile operator swears an oath in all solemnity ground
Claim oneself be following Internet of Things backbone.The connection of automobile, Medical Devices and various electronic products is required to nothing
Institute does not exist, and from the point of view of present case, mobile operator can be with confident.Their 2G, 3G network is current Internet of Things
Main bearer network.Perhaps, the GPS tracker of vehicle or counter only needs to send once the position of oneself daily.Intelligence instrument may
Just give company data back week about.Many built-in sensors from automatic vending machine to monitoring camera only can go out to ask
Data are just transmitted when topic.These can mean that M2M modules connection frequency will well below people contact.In electricity shortage
Expensive today, carries these equipment meaningless with traditional wireless network with frequency spectrum.
Application No. CN201110156184.7, it is entitled《Wirelessly connect based on what cognitive database and frequency spectrum detection were combined
Enter system and method》Patent, ensure that recognizing to the full extent by the way that cognitive database and frequency spectrum detection technology are combined
Know that available free resource allows it to access when terminal sends request, effectively solves hidden terminal problem, frequency spectrum detection module is disposed
In base station, reduce the load of cognitive terminal, it is to avoid because the environment residing for terminal is in shadow fading, cause missing inspection
Or flase drop, so that interference is caused when accessing to authorized user.
The content of the invention

A kind of white frequency spectrum detecting method of TV based on Internet of Things, including step:
Information is sent, terminal in a dormant state is waken up；
After terminal wakes up, one subcarrier of selection sends to enter row information；
After a subcarrier is selected, determine whether that other terminals send information on this subcarrier, if do not had
Have, just directly transmit information；If other terminals send information on this subcarrier, subcarrier is just reselected；
It is multiple subcarriers by the spectral decomposition, when a terminal needs to send information, just automatically selects one
Individual subcarrier is transmitted, it is ensured that when many terminals will send information, the possibility of only minimum collision；
Obtain the information that subcarrier is transmitted；
The white spectrum information of TV in the information and date storehouse that the acquisition subcarrier is transmitted is matched；
Judge whether the information that the acquisition subcarrier is transmitted matches into the white spectrum information of the TV in database
Work(, if obtained, the match is successful, turns next step；If it is unsuccessful to obtain matching, reselect a subcarrier to carry out
Information is sent；
The information being transmitted to the subcarrier that the match is successful carries out pushing to main frame.
Further, described is multiple subcarriers by the spectral decomposition, when a terminal needs to send information, just
Automatically select a subcarrier to be transmitted, it is ensured that when many terminals will send information, only minimum collision can
Can be the step of property：
To each unique subcarrier of terminal distribution one.
Further, described is multiple subcarriers by the spectral decomposition, when a terminal needs to send information, just
Automatically select a subcarrier to be transmitted, it is ensured that when many terminals will send information, only minimum collision can
Can be the step of property：
To the sequence of each one sub-carrier selection of terminal distribution, each terminal is chosen according to this sequence to be sent out
The subcarrier sent, gives a sequence, interruption just selects the subcarrier to be transmitted according to this sequence, to last
Subcarrier.
Further, described is multiple subcarriers by the spectral decomposition, when a terminal needs to send information, just
Automatically select a subcarrier to be transmitted, it is ensured that when many terminals will send information, only minimum collision can
Can be the step of property：
Each terminal produces a subcarrier to be transmitted according to a tandom number generator.This subcarrier is
Randomly generate, in order to ensure minimum collision, it is ensured that the generation of random number can avoid possible collision.
Further, it is described judge the information that is transmitted of acquisition subcarrier whether with the white frequency spectrum of TV in database
Also include after the successful step of information matches：
The information that acquisition subcarrier is transmitted is stored into multiple calculate nodes, each calculate node storage at least one
The information that individual subcarrier is transmitted；
The information back-up that each subcarrier in abnormal calculate node is transmitted is copied in database.
The present invention wakes up terminal in a dormant state by sending information, after terminal wakes up, and one subcarrier of selection comes
Enter row information transmission, after a subcarrier is selected, determine whether that other terminals send information on this subcarrier, such as
Fruit does not have, and just directly transmits information；If other terminals send information on this subcarrier, subcarrier is just reselected,
It is achieved thereby that the white frequency spectrum detection of TV based on Internet of Things.
Brief description of the drawings
Fig. 1 is the inventive method schematic flow sheet.
Embodiment
Below in conjunction with specific embodiment, the present invention is further illustrated：
