Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is string hair infrared remote control system schematic diagram according to the present invention；
Fig. 2 is the keyboard schematic diagram of string hair infrared remote control system according to the present invention；
The workflow of Fig. 3 string hair infrared remote control system according to the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without making creative work it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
In order to facilitate understanding technical solution of the present invention, in the present embodiment by taking two kinds of equipment of television set and CD-audio player as an example into
Row explanation.Fig. 1 show the circuit module figure of string hair IR remote controller according to the present invention.
Including terminal, user can load appliance remote control key interface of the invention in the terminal；
MCU can store several infrared coding mapping tables；
Infrared transmitting circuit receives the control coded command that MCU is sent, thus equipment needed for remote control.
Specifically, the parameters such as quantity, channel, the title of TV station that MCU can be received according to television set are learnt.
For example, TV station's quantity that Beijing Gehua Cable can receive altogether is, for example, 600, then first by its title and channel corresponding relationship
Carry out self study；
Then, infrared coding mapping table is formed in MCU, according to the infrared coding mapping table to the corresponding infrared signal of channel number
It is encoded.Such as it is a set of synthesizer channel in center that channel 1 is corresponding, then it is entitled " central a set of comprehensive can to define key
Close ", as shown in Figure 2.
It is the TVCH for being encoded to paragraph 1 due to being television equipment, it is subsequent to be encoded to 1 that is, until being encoded to 600
Until, as shown in the table.
User passes through downloading or other modes first and key interface and corresponding infrared coding mapping table is loaded into terminal, eventually
End shows corresponding 1-600 television channel key, and user can be by pressing the corresponding TV station's name key of key pressing；
In step 101, user presses the corresponding key of the TV station to be watched, and key command is sent to MCU；
For example, terminal sends the instruction to MCU when user presses the button " Anhui STV "；
Then, in step 102, MCU searches infrared coding mapping table, gets the corresponding infrared coding information of key command；
In this embodiment, if being encoded to 256 in the corresponding Code Mapping Tables in Anhui STV, i.e. MCU receives as TVCH
(television channel) 256 key command, according to infrared coding mapping table is searched, finding out the corresponding field of TVCH in instruction is the 1st
The digital 0-9 of storage in section；
Then, in step 103, the encoded information found is sent to infrared transmitting circuit by MCU；Specific address, MCU can be with every
Every 100ms by storage location be " 02 ", " 05 ", " 06 " corresponding infrared code string issue infrared transmitting circuit；
And then, in step 104, television set is sent to by infrared emission head to complete television station channel switching.
And so on, user can pass through more than 600 one key pressing operations of a corresponding title progress of TV station, so that it may real
Now to the remote control operation of television set.More easily, it is different can also to operate different remote control equipment selections to system of the invention
Entertainment selection, such as CD player etc..
MCU, which can store according to the type of equipment from such as 0-100, can be divided into 10 section controls, and 10 contain 0-9 number
Equipment, such as: the digital 0-9 in paragraph 1 is defined as television equipment TVCH, and the digital 10-19 in the 2nd section is defined as CD and sets
It is standby, and so on.
TV equipment is coding schedule paragraph 1, encodes the numerical order from 0-9 and numbers composition, CD equipment is coding schedule the 2nd
Section encodes the numerical order from 10-19 and encodes composition, as shown in the table:
Similarly, the key in CD equipment can also be encoded according to the corresponding song title of track, for example, storing in CD equipment
Song be 20, the corresponding track of every song is from 1 to 20, and MCU storage infrared coding table is song title and corresponding
Track.For example, the track that song title is " Dongfanghong " corresponds to 119, then when user presses the button " CDCH Dongfanghong ", i.e.,
MCU receives " CDCH Dongfanghong " instruction, then MCU is by searching for infrared coding mapping table, according to the corresponding field of CD in instruction
It for the digital 10-19 of the storage in the 2nd section, is numbered according to track sequence, i.e. the number of track 15 is " 11 ", " 15 ", so
Afterwards MCU every 100ms by storage location be " 11 ", " 15 " corresponding infrared code by infrared emission head be sent to CD completion CD
Track switching.
As described above, user when operating remote control equipment, without inputting corresponding channel or track number, can both complete to want receipts
The program seen or listened to.
The present invention is described in detail above by specific and preferred embodiment, but those skilled in the art should be bright
White, the present invention is not limit to that embodiments describe above, all within the spirits and principles of the present invention, made any modification,
Equivalent replacement etc., should all be included in the protection scope of the present invention.
