Therefore, the combination that the parameter information of each waveform segment may be considered between bottom parameter, each waveform segment is closed
It is that information may be considered upper strata coding.For bottom parameter, that is, each user or producer all can be arranged according to self-demand
Representing same bit, such as user A can be come different parameter informations using " 200 μ s high level+100 μ s low level "
Represent " 0 ", and user B then can represent " 0 " using " 200 μ s low level+100 μ s high level ", but any change of this parameter

Refer to Fig. 2, Fig. 2 shows and implements, according to another exemplary, a kind of information generating method of exemplifying, including with
Lower step：
In step 202., the control function being pre-configured with and the pulsewidth modulation previously generating are described data to be closed
Connection storage；
In the present embodiment, pulsewidth modulation describes and comprises detached bottom parameter and upper strata coding in data.Wherein, bottom
Parameter constitutes the corrugated sheet that this pulsewidth modulation describes the corresponding control signal of data (this control signal is pulse-width signal)
The parameter information of section, the parameter information of bit " 0 " in such as this control signal, " 1 " etc.；Upper strata coding is in bottom data
Each waveform segment between syntagmatic information, thus by control signal final for each waveform segment combination producing.
For realizing separating between bottom parameter and upper strata coding, pulsewidth modulation can be described data configuration is multiple letters
Breath section, then constitute the parameter information of each waveform segment of control signal and described syntagmatic information is located at corresponding letter respectively
In breath section.Refer to Fig. 3, such as pulsewidth modulation describes and comprises each message segment of n, respectively message segment 1, message segment in data
2 ... message segments n.
So that terminal, when parsing pulsewidth modulation describes data, can accurately distinguish bottom parameter therein and upper strata
Coding, syntagmatic information can be located in the message segment of predeterminated position, and constitute each ripple of described pulse-width signal
The parameter information of shape fragment is located in remaining message segment respectively.For example as illustrative embodiments, can be by syntagmatic
Information is placed in last message segment that pulsewidth modulation describes in data, i.e. message segment n shown in Fig. 3, and by parameter information
It is placed in remaining message segment 1 to message segment n-1.Wherein, because the corresponding bit of parameter information has certain versatility,
Such as bit " 0 ", " 1 " etc., thus can also be the fixing message segment of these parameter informations setting, such as make first letter
Breath section (i.e. message segment 1 shown in Fig. 3) corresponds to bit " 0 ", second message segment (i.e. message segment 2 shown in Fig. 3) corresponds to
In bit " 1 " etc..
In fact, although the content that pulsewidth modulation describes each message segment in data is different, each message segment can be adopted
Use identical data structure.At least one of information of following types is all included in such as each message segment：
1) pulsewidth sequence
As illustrative embodiments, pulsewidth sequence specifically can include persistent period and the instruction electricity of each pulse
Flat, can adopt from syntactic description：
width::[+|-]integer
width_seq::/(width(,width)*/)
Than as shown in figure 4, the pulsewidth sequence (+200, -100) in message segment describes one by 200 μ s high level and 100
The waveform segment that μ s low level is constituted.Certainly, it is not limiting as the number of pulses that device comprises, such as (+300) description in pulsewidth sequence
The waveform segment of one 300 μ s high level, and (+200, -100 ,+300) describe one low by 200 μ s high level, 100 μ s
Level and the waveform segment of 300 μ s high level composition.
Wherein, multiple pulsewidth sequences can be superimposed, such as (+200, -100) (+300) and (+200, -100 ,+300) phase
Same, all describe a waveform segment being made up of 200 μ s high level, 100 μ s low levels and 300 μ s high level.Meanwhile, if
There are multiple pulses, then posterior pulse can not comprise to indicate level, represents the level continuing a pulse before it, such as
(+200,100) describe the waveform segment of 300 μ s (100 μ s high level of 200 μ s high level and continuity) high level,
(+200, -100) (300) describe one by 200 μ s high level and 400 μ s low levels (the 300 of 100 μ s low levels and continuity
μ s low level constitute) waveform segment.
2) reference information
As illustrative embodiments, can mutually quote between each message segment, to reduce repeated data amount.Wherein,
Can be quoted based on unique ID of different message segments, then corresponding syntactic description can adopt：
seg_ref::/[integer/]
In above-mentioned syntactic description, pulsewidth sequence " () " is distinguished over using " [] ", the message segment being wherein cited is only
One ID can describe putting in order in data for this message segment in pulsewidth modulation.Than as shown in Figure 5 it is assumed that pulsewidth modulation describes
Comprise three message segments in data, message segment 1, message segment 2 and the message segment 3 being respectively arranged in order, then message segment 1 correspond to
Arrangement position 0, message segment 1 correspond to arrangement position 1, message segment 2 corresponds to arrangement position 2.It is assumed that comprising pulsewidth in message segment 1
Sequence (+200, -100), describes a waveform segment being made up of 200 μ s high level and 100 μ s low levels, and message segment 2
In comprise pulsewidth sequence (- 200 ,+100), describe a waveform segment being made up of 200 μ s low levels and 100 μ s high level,
And in message segment 3, comprise reference information [0] [1] [0], represent to the message segment 1 of arrangement position 0 and the message segment 2 of arrangement position 1
Quote successively, then corresponding pulse-width signal is：(+200, -100) (- 200 ,+100) (+200, -100), that is, high by 200 μ s
The waveform segment that level, 300 μ s low levels, 300 μ s high level and 100 μ s low levels are constituted.
It should be noted that：" pulsewidth sequence " and " reference information " can be used in combination, than message segment 1 as shown in Figure 5
In the case of constant with message segment 2, message segment 3 can be [0] [1] [0] (+200, -100), then to message segment 1 and message segment
On the basis of 2 are quoted, also continue a waveform segment being made up of 200 μ s high level and 100 μ s low levels.
3) pulsewidth Delay
As illustrative embodiments, pulsewidth Delay can using "<>" distinguishing over pulsewidth sequence " () " and to draw
With information " [] ", and the syntactic description of pulsewidth Delay can adopt：
width_until::/<width/>
As illustrative embodiments, pulsewidth Delay only can include decay time, and this decay time is from corresponding
Pulsewidth sequence calculate when starting, and if decay time is more than the total duration of this pulsewidth sequence, in this pulsewidth sequence knot
Shu Hou, maintains pulse to export according to level during this pulsewidth EOS and terminates to decay time.Than as shown in Figure 6 it is assumed that believing
Parameter information in breath section is (+200, -100)<500>, then describe one by 200 μ s high level, 100 μ s low levels and 200
μ s low level (the instruction level at the end of 500-200-100=200, and (+200, -100) be low level, therefore (+200, -
100) one 200 μ s low level of time delay after) waveform segment that constitutes.
As another exemplary embodiment, pulsewidth Delay can also include：Time delay level, is used for making corresponding arteries and veins
After wide EOS, maintain pulse to export according to this time delay level and terminate to decay time.Than as shown in Figure 7 it is assumed that message segment
In parameter information be (+200, -100)<+500>, then describe one by 200 μ s high level, 100 μ s low levels and 500 μ s
The waveform segment that high level is constituted.
It should be noted that：
First, based on the definition of pulsewidth Delay, if then the decay time length of pulsewidth Delay is less than front
Pulsewidth sequence total duration, such as (+200, -100)<+200>Or (+200, -100)<+300>, then due to front pulsewidth sequence
The total duration of row is 300 μ s so that during this pulsewidth EOS, decay time is also over, then above-mentioned two parameter information
Only describe a waveform segment being made up of 200 μ s high level and 100 μ s low levels, that is, pulsewidth Delay is practically without
Work.
Second although in Fig. 6 and Fig. 7, comprise pulsewidth sequence and pulsewidth Delay simultaneously in message segment, but pulsewidth time delay
Information can also be used alone, and such as passes through only to arrange<0>Length of a game is zeroed out operate to represent.
3rd, pulsewidth Delay can also be used in combination with reference information, or by pulsewidth sequence, reference information and pulsewidth
Delay is used in combination, and is extended with the waveform realized based on length of a game and controls.Such as in the embodiment shown in fig. 5, false
Determine message segment 1 and message segment 2 constant in the case of, message segment 3 can be [0] [1] [0]<1000>, then to message segment 1 and letter
Breath section 2 quoted on the basis of, due to " [0] [1] [0] " total duration be 900 μ s, and at the end of be low level, thus knot
Remain a need for after bundle continuing the low level of 100 μ s (1000-900=100)；Or, such as in the embodiment shown in fig. 5 it is assumed that
Message segment 1 and message segment 2 constant in the case of, message segment 3 can be [0] [1] [0] (+200, -100)<1000>, then to letter
Breath section 1 and on the basis of message segment 2 quoted, has also continued the high level of 200 μ s and the low level of 100 μ s, then due to
The total duration of " [0] [1] [0] (+200, -100) " is 1200 μ s, beyond "<1000>" the time delay duration of 1000 μ s that limits,
Thus "<1000>" actually will not work.
4) loop computation information
As illustrative embodiments, the syntactic description of loop computation information can adopt：
op_exp::integer'*'width_seq|integer'*'seg_ref|integer'*'width_until
As illustrative embodiments, loop computation information can to any pulsewidth sequence in affiliated message segment, draw
It is circulated computing with information and/or pulsewidth Delay.Than as shown in Figure 8 it is assumed that parameter information in message segment be 2* (+
200, -100), then describe one to be made up of 200 μ s high level, 100 μ s low levels, 200 μ s high level and 100 μ s low levels
Waveform segment, actually 2 times have been calculated to " 200 μ s high level and 100 μ s low levels " circulating.
Meanwhile, loop computation information can also be circulated computing to reference information, than message segment 1 as shown in fig. 5
In the case of constant with message segment 2, message segment 3 can comprise " 2* [0] ", then indicated to message segment 1 circular reference 2 times,
Be equivalent to " 2* (+200, -100) ".
Similarly, loop computation information can also be circulated computing, such as 2* to pulsewidth Delay<+100>Of equal value
In<+100><+100>It is equivalent to<+200>.
In step 204, when user's trigger event is detected, determine that default control function is triggered, and proceed to step
Rapid 206；
In step 206, " control function-pulsewidth modulation describes data " data pair based on associated storage in advance, searches
The pulsewidth modulation corresponding with the control function being triggered describes data；
In a step 208, read pulsewidth modulation and describe the syntagmatic information in data；
In this embodiment it is assumed that signal transmitting chip is mounted with terminal, the oscillation frequency of the oscillation resistance in this chip
Rate is 1.2MHz, then about T=37.5 μ s of corresponding clock cycle.It is assumed that needing the control signal of transmitting by " 0 ", " 1 " and " z "
Constitute, then the parameter information constituting the waveform segment of corresponding control signal can be as shown in table 1 below：
| Arrangement position | Parameter information | Implication |
| [0] | 2*[4] | Bit " 0 " |
| [1] | 2*[5] | Bit " 1 " |
| [2] | [4][5] | “z” |
| [3] | (+150, -4650) | Synchronous code |
| [4] | (+150, -450) | (+4T, -12T) |
| [5] | (+450, -150) | (+12T, -4T) |
| [6] | [2][2][2][1][2][2][1][2] | Address code |
| [7] | [6][2][1][2][2][3] | Code word |
Table 1
In which it is assumed that numeric data code is " [2] [1] [2] [2] in [7].If control signal need by " address code+numeric data code+
Synchronous code " constitutes one group of code word, and needs 4 groups of code words during each transmitting, then corresponding syntagmatic information can be：4* [7],
I.e. complete pulsewidth modulation describes data and includes：
2*[4]；2*[5]；[4][5]；(+150, -4650)；(+150, -450)；(+450, -150)；[2][2][2][1]
[2][2][1][2]；[6][2][1][2][2][3]；4*[7]；
Therefore, terminal pass through read " 4* [7] ", and and then other information section is parsed, and by (+150, -4650),
(+150, -450) and (+450, -150) combine to constitute final control signal.
In above-described embodiment, so that the frequency of oscillation of oscillation resistance is as 1.2MHz as a example, give above-mentioned pulsewidth modulation description
Data；And when frequency of oscillation changes, such as frequency of vibration is 4.3MHz, then only corresponding clock cycle T changes,
I.e. arrangement position [3], arrangement position [4] and arrangement position [5] change, and remaining message segment all need not change.
In step 210, generate corresponding control signal.
