Detailed description of the invention
In order to make those skilled in the art can further appreciate that inventive feature and technology contents, refer to
Below in connection with detailed description of the invention and accompanying drawing, accompanying drawing only provides reference and explanation, is not used for limiting
The present invention.
First clear and definite two definition once were needed before describing the embodiment of the present application, in the embodiment of the present application,
Wide envelope modulation refers to repeat character in units of byte several times, and by several repeat character (RPT)s
As a character；As, character to be transmitted is " 00011010 ", and the widest envelope modulation is exactly will
" 00011010 " repeated several times, and " 00011010 " repeated these several is as a character
Be transmitted, it is assumed that number of repetition is 7, then " 00011010 " character after wide envelope modulation is
“00011010000110100001101000011010000110100001101000011010”；Namely
Saying, wide envelope modulation is to repeat information to be transmitted in units of byte, as wide envelope modulation tool
During body application, using a how many repeat character (RPT) to represent a character, the present invention is not specifically limited.
Wide envelope demodulation is the inverse process of wide envelope modulation.
Embodiment one is with reference to Fig. 1, a kind of remote control information method of reseptance provided for the embodiment of the present invention one
Flow chart, including:
Step S101: receive request for building link, respectively application communication agreement and two kinds of sides of wide envelope demodulation
Described request for building link is resolved by formula；
When receiving request for building link, in order to judge that it is that communication link based on agreement sets up request
Or wide envelope request for building link, uses communication protocol and wide envelope demodulation two ways to link respectively
Foundation request resolves, if request for building link is wide envelope request for building link, then application is logical
When it is resolved by letter agreement, communication protocol will report an error when resolving.
Request for building link is resolved, it is simply that request for building link is demodulated process, by right
Request for building link is demodulated judging whether request for building link meets wide envelope modulation mode, it is simply that
Judge whether request for building link is to represent a character with several repeat character (RPT)s.And judge link establishment
Request be whether communication protocol modulation system be known, repeat no more here.
Step S102: when the parsing of described communication protocol reports an error, and described request for building link meets wide envelope
During modulation system, switch to wide envelope modulation demodulation mode of operation, and send link establishment response message；
Concrete, when communication protocol interpretive model reports an error and described request for building link is to use some pleonasms
When Fu represents a character, being judged as described request for building link is wide envelope modulation mode, is switched to width
Envelope modulation demodulation mode of operation, and send link establishment response message；
In specific implementation process, can not exclusively synchronize owing to controlling end and controlled terminal, data are passing
Defeated process may produce error code, so can resolve correctly in order to ensure receiving data, needs width bag
Data after network demodulation are filtered, concrete, can be with majority vote as filter criteria, say, that
When in modulation data, the number of repetition of character meets pre-conditioned, can be specifically that number of repetition exceedes half
During number, it is believed that it is wide envelope modulation, and this character is exactly the character controlling end transmission.
Below as a example by " 00011010 " is carried out wide envelope modulation, set number of repetition here as 7, then
Correct modulation result should be
" 00011010000110100001101000011010000110100001101000011010 ", but because of
For transmission link there may be error code, so, the wide envelope modulation information received may be
" 00011010000110100001101000011010000110110001101000011010 ", because wide
Envelope modulation is the modulation carried out in units of byte, so demodulating process also to be carried out in units of byte
Demodulation, but owing to link existing error code, the most above-mentioned wide envelope modulation information received is being carried out
During demodulation, parsing and the most not exclusively meet wide envelope modulation mode, analysis result is " 00011010 "
Occur 6 times, and " 00011011 " occurs 1 time, but the number of times that " 00011010 " occurs accounts for repetition time
The major part of number, accounts for 6/7, accordingly, it is possible to illustrate that its modulation system is wide envelope modulation, and receives
The data arrived are " 00011010 ".As long as it is to say, the number of repetition of " 00011010 " accounts for total weight
Again, on the half counted, the data being considered as receiving are correct.
Specifically when demodulation, the number of repetition of the data parsed can be the repetition that modulation system uses
Any value on the half of number of times, i.e. if the number of repetition that modulated process uses is N, demodulate
The number of repetition of the data come is n, then, as long as n > N/2, the data being considered as receiving are correct.n
Occurrence can be the number that user oneself specifies based on experience value.
When described communication protocol resolves correct, whether the widest envelope demodulation parses request for building link
Meet wide envelope modulation mode, all do not switch to wide envelope modulation demodulation mode, and be to maintain work at present
Pattern, i.e. continues application communication agreement and communicates.
Report an error when described communication protocol resolves, and described request for building link does not meets wide envelope modulation side yet
During formula, send fault alarm information.
Step 103: receive remote control information by described link.
Just can be set up wide envelope communication link by above-mentioned two step, this communication link is not dependent on
Communication protocol, namely unrelated with communication protocol, so after setting up wide envelope communication link, with regard to energy
Remote control information is received by this width envelope communication link.

When certain unit of view breaks down, the communication link controlled between end and controlled terminal will interrupt, quilt
Controlling end and will take off pipe, controlling end cannot be controlled controlled terminal, the de-pipe of controlled terminal detected
Time, it is switched to wide envelope modulation demodulation mode of operation, then sends wide envelope communication link to controlled terminal
Setting up request, this width envelope communication request for building link also sends after wide envelope modulation.
Step S202: after receiving link establishment response message, carries out width to control message waiting for transmission
Envelope modulation, and the control information after wide envelope modulation is entered by the wide envelope communication link set up
Row sends.
After receiving link establishment response message, illustrate to have been set up wide envelope communication link, at this moment
