The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of flow diagram for Internet of Things electric appliance baud rate adjusting method that the embodiment of the present invention one provides, this
The technical solution of embodiment can be applied in the scene for needing that Internet of Things electric appliance baud rate is adjusted, can be by of the invention real
The Internet of Things electric appliance baud rate regulating device for applying example offer executes, the system can by the way of software and/or hardware come
It realizes, which can integrate in the Internet of Things electric appliance for having baud rate regulatory function, such as air-conditioning.This method comprises:
S110 acquires multiple pulse signals, measures the width of pulse signal.
Internet of Things electric appliance acquires multiple pulse signals that sender unit is sent, and measures the width in pulse signal,
The width of pulse signal refers to high level pulse duration in pulse signal, i.e., rising edge and next phase in pulse signal
The distance between adjacent failing edge.Common baud rate includes 4800 bauds, 9600 bauds and 19200 bauds, can be seen by above-mentioned
Out based on 4800 bauds, other baud rates are all the multiples of 4800 bauds., therefore baud rate is 4800 by the embodiment of the present invention
Base of the width of the pulse signal of baud as width 1, that is, the width for the pulse signal being subsequently noted are 4800 waves
The integral multiple of the width of special pulse signal.In addition, illustrative, sender unit can be router or interchanger, usually
For wireless router, sender unit can send the letter of impulse form to the electric appliance such as Internet of Things electric appliance of peripheral region
Number.It should be noted that when acquiring multiple pulse signals difference can also be acquired with the multiple pulse signals of continuous acquisition
Multiple continuous impulse signals in timing node, the embodiment of the present invention are not construed as limiting this.
S120 is handled pulse signal according to width, obtains minimum widith, and obtain pulse letter according to minimum widith
Number baud rate.
Pulse signal is handled according to width to obtain minimum widith, in minimum widith, that is, collected pulse signal
It transmits the time required for a data, and the baud rate of pulse signal represents the transmission rate of data, i.e., passes in the unit time
The data bits sent.
Optionally, carrying out processing according to multiple pulse signals of the width to acquisition may include following processing operation:
Firstly, carrying out ascending order arrangement according to width to the unequal pulse signal of all width, i.e., by all width not phase
Deng pulse signal arranged according to the sequence of width from small to large.Illustratively, the width example of collected pulse signal
It such as can be { 3,2,2,5,3,5,8,5 }, the arteries and veins that ascending order arranges carried out to the unequal pulse signal of width { 3,2,5,8 }
Rushing signal is { 2,3,5,8 }.
Then, the width of successive pulse signals is subtracted each other one by one, will subtracts each other afterwards and subtract each other preceding all unequal arteries and veins of width
It rushes signal and ascending order arrangement is re-started according to width, generate reference burst signal queue.Illustratively, there are n width before subtracting each other
Unequal pulse signal, the successive pulse signals being sequentially arranged successively from small to large according to width carry out width and subtract each other one by one,
That is the width of current PRF signal subtracts the width of previous item pulse signal, then obtains n-1 pulse signals after subtracting each other, will subtract each other
Rear n-1 item pulse signal with subtract each other before n item pulse signal in the unequal total m pulse signal of width according to width again
Ascending order arrangement is carried out, a reference burst signal queue is generated.Illustratively, obtained with previous step pulse signal 2,3,5,
8 } for, the width of successive pulse signals is subtracted each other one by one, will subtracts each other afterwards and subtract each other preceding all unequal pulse signals of width
Re-starting the pulse signal that ascending order arranges according to width is { 1,2,3,5,8 }.
Subtract each other one by one secondly, being recycled to reference burst signal queue and carrying out width and operation is arranged according to width ascending order, directly
Pulse is believed in the first reference burst signal queue and latter the second reference burst signal queue generated generated to previous time
Number item number is identical.Illustratively, width is carried out one by one to the m item pulse signal in the reference pulse queue formed in previous step
Subtract each other, and before subtracting each other with subtract each other after pulse signal in the unequal pulse signals of all width carry out ascending order arrangements, and it is raw
The reference burst signal queue of Cheng Xin, recycles according to this, until to the unequal pulse signal of all width according to width after pth time circulation
Degree ascending order arrange the first reference burst signal queue to be formed with pth+1 time circulation to the unequal pulse signal of all width according to
It is identical that width ascending order arranges pulse signal terms number in the second reference burst signal queue to be formed, illustratively, when the first reference
When having the unequal pulse signal of q width in pulse signal queue and the second reference burst signal queue, then stop width
The circulate operation subtracted each other one by one and arranged according to width ascending order.Illustratively, obtained with previous step pulse signal 1,2,3,
5, for 8 }, the width of successive pulse signals is subtracted each other one by one, will subtracts each other afterwards and subtract each other preceding all unequal pulses of width and believes
Number re-starting the pulse signal that ascending order arranges according to width remains as { 1,2,3,5,8 }, at this point, previous first ginseng
Pulse in pulse signal queue { 1,2,3,5,8 } and rear primary the second reference burst signal queue { 1,2,3,5,8 } is examined to believe
Number item number is identical, is 5, then stops the circulate operation that width subtracts each other one by one with arranges according to width ascending order.
Finally, using the width of the first term pulse signal of the second reference burst signal queue as minimum widith.Illustratively,
Resulting the second reference burst signal queue for having the q unequal pulse signals of width of above-mentioned steps is by q width not phase
Deng pulse signal carry out ascending order and arrange, therefore the width of the first term pulse signal in the second reference burst signal queue
Minimum passes through the above-mentioned processing to pulse signal according to width in this way, has obtained minimum widith as minimum widith.Show
Example property, by taking the second reference burst signal queue { 1,2,3,5,8 } that previous step obtains as an example, by the second reference burst signal
The width 1 of first term pulse signal in queue is used as minimum widith.
Due to the unequal arteries and veins of q item width in the second obtained reference burst signal queue after p+1 circulation
The case where rushing signal there may be such as { 2,4,6,8,10 }, if in this way using the first term of the second reference burst signal queue as most
Small width can not then obtain the baud rate of pulse signal according to first term, therefore, it is necessary to according to width to pulse signal at
Reason, obtains minimum widith, illustratively, can be according to the width for judging all pulse signals in the second reference burst signal queue
Whether whether relatively prime determining minimum widith is correct.Correspondingly, if the width of the pulse signal in the second reference burst signal queue
Relatively prime, then the width of the first term pulse signal after the second reference queue is as minimum widith.
It illustratively, include the width of q ascending orders arrangement in the second reference burst signal queue obtained after recycling p+1 times
Unequal pulse signal, but can not directly make the width of the first term pulse signal in the second reference burst signal queue
For minimum widith, because the width of the q item pulse signal in the second reference burst signal queue is possible to not relatively prime, i.e. q
The greatest common divisor of the width of pulse signal is not 1, if the case where the greatest common divisor of the width of q pulse signals is not 1
It is lower using the width of the first term pulse signal in the second reference burst signal queue as minimum widith, it is understood that there may be in minimum widith
The data for including not only one, the baud rate of acquisition pulse signal can not be obtained according to minimum widith in this way.Therefore, only second
When the width of all pulse signals is relatively prime in reference burst signal queue, second could be believed with reference to the first term pulse after queue
Number width as minimum widith.
If the width of the pulse signal in the second reference burst signal queue is non-relatively prime, multiple pulse letters are resurveyed
Number, the width of pulse signal is measured, is handled according to pulse signal, until the pulse in the second reference burst signal queue
The width of signal is relatively prime.Specifically, if the width of the pulse signal in the second reference burst signal queue is non-relatively prime, i.e. most grand duke
Approximate number is not 1, then resurveys multiple pulse signals of sender unit transmission, the width of pulse signal is measured, according to width
Degree handles pulse signal, until the width of the pulse signal in the second reference burst signal queue is relatively prime, then assert this
A data is transmitted in the width of the first term pulse signal of second reference burst signal queue of Shi Zuowei minimum widith, by
The width of the first term pulse signal of two reference burst signal queues is as minimum widith.In this way according to the second reference burst signal team
Whether the width of all pulse signals is relatively prime in column determines whether to make second with reference to the width of first term pulse signal in queue
For minimum widith, the interference as caused by the special burst signal generated in some cases is avoided, Internet of Things electric appliance is improved
Baud rate regulating device is handled to obtain the accuracy of minimum widith pulse signal according to width, and then is improved according to minimum
Width obtains the accuracy of pulse signal baud rate and instrumentality networked appliance baud rate.
The baud rate of minimum widith and pulse signal is in reciprocal relation, obtains minimum widith, can be obtained according to reciprocal relation
Obtain the baud rate that sender unit sends pulse signal.
It should be noted that may during sender unit sends pulse signal being obtained according to reciprocal relation
The measurement for occurring to the width of pulse signal the case where there are errors, lead to the arteries and veins obtained according to minimum widith according to reciprocal relation
Rushing the baud rate of signal, there is a certain error, can be by the baud rate of the pulse signal of acquisition and 4800 bauds, 9600 bauds
It makes comparisons with 19200 bauds, and the baud rate for obtaining pulse signal is adjusted to eliminate error according to comparison result.
S130 adjusts the baud rate of itself according to the baud rate of pulse signal.
Specifically, the inverted sender unit that obtains of minimum widith that above-mentioned steps obtain is sent pulse signal
Baud rate matches the two baud rate according to the baud rate that the baud rate of pulse signal adjusts itself.When sender unit is sent out
When the baud rate of the pulse signal sent changes, the baud rate of pulse signal can be obtained according to minimum widith, and according to arteries and veins
The baud rate for rushing the baud rate instrumentality networked appliance of signal completes oneself of pulse signal that Internet of Things electric appliance change baud rate
It adapts to.
