Fig. 1 is a kind of infrared remote control that provides of the embodiment of the present invention one to code method flow schematic diagram.As shown in Figure 1, should
Infrared remote control includes to code method：
S10 is sent to controlled device to code signal, and described includes pair at least two different amplitudes to code signal
Code waveform, so that the controlled device generates the response waveform with strength information value according to described to code waveform.In this implementation
In example, for example, if what is be remotely controlled before infrared remote control equipment is other controlled devices, when infrared remote control equipment will be remotely controlled
When target controlled device, need first to send to code signal to target controlled device, to start remote control to code process.
It, can be by code signal and response letter in order to distinguish the difference to code signal, answer signal and remote signal
Preset harbour is set to make remote control equipment and controlled device recognize to code signal and answer signal, or can also be fixed in number
Preset code value information is set in code or numeric data code processed, remote control equipment and controlled device is made to recognize to code signal and answer signal etc.
Deng the present embodiment does not limit this.If after controlled device receives this to code signal, parsing, obtaining to code signal to this
Take that it includes preset harbours, it is determined that remote control equipment has initiated remote control to code process, i.e., according to carrying preset harbour
To code signal, corresponding answer signal is generated, and the answer signal is returned to remote control equipment.It is controlled that remote control equipment receives target
After the answer signal that equipment returns, find that the answer signal includes corresponding with preset harbour to code harbour by parsing,
Then determine that the signal is answer signal.
Wherein, can be the waveform at least two different amplitude arbitrary shapes to code waveform, for example, Ke Yiwei
A series of pulse type waveform of difference amplitudes, alternatively, can also be as shown in Fig. 2, being step-like waveform, different platforms to code waveform
Rank corresponds to different amplitudes, i.e., different steps corresponds to different strength grades.Fig. 2 is provided by the invention a kind of to code signal
Waveform diagram.As shown in Fig. 2, the harbour in Fig. 2, is preset harbour, each step of step-like waveform represents one
Emissive porwer grade, each length of bench of step-like waveform are t, indicate that the duration of the intensity is t, in default harbour and
One time interval T can be set between step-like waveform, so that controlled device is received to identifying the default harbour after code signal,
After controlled device recognizes the default harbour, you can return to answer signal to remote control equipment, and carry quilt in answer signal
Control equipment recognize to code shape information.
It is assumed that all controlled devices are identical for infrared reception ability, then under remote control equipment different distance, it is controlled
The amplitude to code waveform that equipment obtains is different, and the distance due to each controlled device apart from remote control equipment is different, same
On direction, the intensity for the infrared signal that the controlled device remoter apart from remote control equipment receives is weaker, in different directions, with
In the different controlled devices of remote control equipment same distance, remoter controlled device, connects with remote control equipment infrared emitting center line
The intensity of the infrared signal received is weaker.For convenience of description, present invention different distance mentioned below, refers both in the same direction
Different distance.
Show as shown in figure 3, Fig. 3 is a kind of step-like waveform that controlled device receives under different distance provided by the invention
It is intended to.In Fig. 3 from remote control equipment it is nearest with a distance from be L1, from remote control equipment it is time close with a distance from be L2, it is farthest from remote control equipment
Distance is L3, it can be seen from the figure that the signal of step-like waveform is most strong at L1, the signal of step-like waveform is most at L3
It is weak.Controlled device can generate the response waveform with strength information value when receiving to code waveform, and the shape of response waveform can be with
It is identical as to code waveform, it can also be different.The response waveform that the present embodiment combination Fig. 4 is generated using controlled device is pulse type waveform
For illustrate.
Fig. 4 is the answer signal portion waveshape schematic diagram that controlled device generates under a kind of different distance provided by the invention.
From figure 5 it can be seen that since controlled device recognizing step-like waveform, just generate high level signal, i.e. pulse type waveform,
Pulse type waveform is continued until that step-like waveform terminates, i.e. the duration of pulse type waveform can recognize that platform with controlled device
The time of step-like waveforms is identical, that is to say, that the duration of pulse type waveform and controlled device receive to the strong of code waveform
Spend it is related, then the pulse type waveform can be added in the answer signal that controlled device returns as strength information value, from
And at a distance from making remote control equipment according to the strength information value and determining controlled device between remote control equipment.
S11, obtains at least one answer signal that the controlled device returns, the answer signal include described in have
The response waveform of strength information value and the identifiable code value information of the controlled device.
In the present embodiment, if remote control equipment transmission is only received code signal by a controlled device, then remote control is set
The standby answer signal got also only there are one, but in actual use, might have in a usual region multiple infrared
Controlled device may be received, accordingly then when remote control equipment is sent to code signal by multiple controlled devices in the region
Remote control equipment also will receive the answer signal that multiple controlled devices return.
In the present embodiment, controlled device is received to after code signal, knowing that remote control equipment has been initiated to be remotely controlled to code process,
A code value information is then generated according to its identifiable coding, or intercepting a part from its identifiable coding can as it
The code value information of identification, or its pre-stored identifiable code value information is taken out, so that its identifiable code value is believed
Breath carries in answer signal, returns to remote control equipment.
Wherein, code signal and answer signal can be encoded by common infrared remote-controlled signal coded format, such as
Including harbour, customization code and numeric data code, can also be encoded according to the coded format of other infrared rays, the present embodiment is to this
It does not limit.
For example, in the present embodiment, in order to distinguish the difference to code signal, answer signal and remote signal, Ke Yitong
It crosses in code signal and answer signal and preset harbour is set to make remote control equipment and controlled device recognize to code signal and answer
Signal is answered, or can also preset code value information be set in customization code or numeric data code, remote control equipment and controlled device is made to distinguish
Know to code signal and answer signal etc., the present embodiment does not limit this.Right after if controlled device receives this to code signal
This parses code signal, and it includes preset harbours for acquisition, it is determined that remote control equipment has initiated remote control to code process, i.e. root
According to carry preset harbour to code signal, generate corresponding answer signal, and the answer signal is returned to remote control equipment.It is distant
Control equipment receive target controlled device return answer signal after, by parsing find the answer signal include with it is preset
Harbour is corresponding to code harbour, it is determined that the signal is answer signal.
In addition, when remote control equipment transmission is after being received code signal by controlled device, to prevent multiple controlled devices simultaneously
Answer signal is returned, and it is chaotic to cause remote control equipment to receive, controlled device needs timesharing to return to answer signal to remote control equipment.Citing
For, controlled device can return to answer signal according to the priority sequence table of preset controlled device, for example set-top box exists
Priority sequence table is in third position, then set-top box, can be after empty two sigtnal intervals again to remote control after receiving to code signal
Equipment returns to answer signal.Alternatively, the step-like waveform that controlled device can also be received according to oneself, determines that oneself sets to remote control
The standby time for returning to answer signal, for example, if controlled device is to receive step-like waveform since third step, that
Controlled device just returns to answer signal to remote control equipment again after three sigtnal intervals, if or controlled device is from second platform
Rank starts to receive step-like waveform, then controlled device just returns to response letter to remote control equipment again after two sigtnal intervals
Number, and so on.In the case of certain is special, if the step-like waveform that two controlled devices receive is identical, then this
When two controlled devices return to answer signal to remote control equipment, remote control equipment will receive mixed opinion, and remote control equipment can pass through at this time
The mode for sending alarm signal notifies user to code procedure failure, the convertible operating position of user, to restarting pair
Code process.
S12 will be determined as target quilt at least one answer signal comprising the maximum answer signal of strength information value
Control the answer signal of equipment.
S13 determines the coding of infrared remote control equipment according to the code value information in the answer signal of the target controlled device
Mode.
It is understood that user is when replacing the coding mode of remote control equipment, it will usually by remote control equipment alignment target
Controlled device, and since the reception ability of controlled device is identical, then the amplitude to code waveform that target controlled device receives
Will be maximum, correspondingly, the strength information value for the response waveform that target controlled device generates is also bigger, therefore, in the present embodiment
Remote control equipment will be determined as the answer signal of target controlled device comprising the maximum answer signal of strength information value.Remote control equipment exists
After target controlled device is determined, you can the target controlled device that the answer signal according to target controlled device includes is recognizable
Code value information, determine the coding mode of remote control equipment.
For Fig. 4, when controlled device is remoter apart from remote control equipment, the pulse type waveform in answer signal is narrower, i.e.,
Strength information value is smaller, to which remote control equipment can judge that each be controlled sets according to the strength information value in the answer signal received
It is standby between remote control equipment at a distance from, the widest signal of pulse type waveform is determined as to the answer signal of target controlled device.
In addition, when remote control equipment transmission is after being received code signal by controlled device, to prevent multiple controlled devices simultaneously
Answer signal is returned, and it is chaotic to cause remote control equipment to receive, controlled device needs timesharing to return to answer signal to remote control equipment.Citing
For, controlled device can return to answer signal according to the priority sequence table of preset controlled device, for example set-top box exists
Priority sequence table is in third position, then set-top box, can be after empty two sigtnal intervals again to remote control after receiving to code signal
Equipment returns to answer signal.Alternatively, the step-like waveform that controlled device can also be received according to oneself, determines that oneself sets to remote control
The standby time for returning to answer signal, for example, if controlled device is to receive step-like waveform since third step, that
Controlled device just returns to answer signal to remote control equipment again after three sigtnal intervals, if or controlled device is from second platform
Rank starts to receive step-like waveform, then controlled device just returns to response letter to remote control equipment again after two sigtnal intervals
Number, and so on.In the case of certain is special, if the step-like waveform that two controlled devices receive is identical, then this
When two controlled devices return to answer signal to remote control equipment, remote control equipment will receive mixed opinion, and remote control equipment can pass through at this time
The mode for sending alarm signal notifies user to code procedure failure, the convertible operating position of user, to restarting pair
Code process.
In the present embodiment, for example, can be in store each identifiable code value information of controllable device in remote control equipment
Pass through inquiry after remote control equipment gets the answer signal of target controlled device return with the mapping table of coding mode
The mapping table of the code value information and coding mode that are locally stored determines and the identifiable code value information pair of target controlled device
The coding mode answered, to configure the coding mode of the determination to the current coding mode of remote control equipment.
S14 sends remote signal according to the coding mode to target controlled device.
In the present embodiment after determining coding mode, remote control equipment can utilize determination according to instruction input by user
Coding mode generate remote signal after, target controlled device is sent to, so that target controlled device receives the remote signal
Afterwards, it is operated accordingly according to the remote signal, such as increase and decrease volume, zapping, tune wind etc..
For infrared remote control provided in this embodiment to code method, it includes having that infrared remote control equipment is sent to controlled device first
At least two different amplitudes to code signal, it includes having answering for strength information value to receive controlled device later and return at least one
After answering signal, the response for being determined as target controlled device in answer signal comprising the maximum answer signal of strength information value is believed
Number, the coding mode of the remote control equipment is determined according to the code value information in the answer signal of target controlled device later.This is red
Outer remote control is to code method, and remote control equipment includes at least two difference amplitudes to code signal by being sent to controlled device, later

In the present embodiment, after remote control equipment determines the answer signal of target controlled device, by analyzing in answer signal
Pulse type waveform can determine the number of steps of step-like waveform that target controlled device receives, for example, if target is answered
The rising edge for answering the pulse type waveform in signal is corresponding with to the 5th step in code signal, then illustrates that target controlled device can
The minimum signal strength received is the corresponding transmitting signal strength of the 5th step, then remote control equipment is set to target is controlled
When preparation send remote signal, then it can emit infrared signal with the corresponding transmitting signal strength of the 5th step, or in order to ensure to use
When family is moved in a certain range, target controlled device energy reliable reception remote signal, the emissive porwer of remote signal can be set
Fixed emphasizes that slightly big preset value, such as the emissive porwer of target response signal correspond to the 5th platform than target response signal
The emissive porwer of the corresponding transmitting signal strength of rank, remote signal can correspond to the 6th, the 7th or the 8th corresponding hair of step
Penetrate signal strength.The present invention does not limit this.
It can be understood that more to the number of steps of step-like waveform in code signal, i.e., emissive porwer grade classification is closeer.
Consider in the same space, different controlled devices between remote control equipment at a distance from be extremely difficult to absolutely consistent, i.e., controlled device receives
