Protocol communication method and device.
Background technique
Large-scale Internet of Things application brings wireless aware and controls flourishing for application, most common wireless
Network standard is WiFi, ZigBee and Bluetooth, and working frequency range is all in the free frequency range of 2.4GHz.Under many scenes,
The interference that these heterogeneous devices coexisting in physical space inevitably will lead to respective wireless communication system by other side
And mutual channel competition.In order to realize, the transmission of more effective data and frequency spectrum are used between heterogeneous device, these are heterogeneous to set
Need to carry out the transmission and exchange of information between standby.The work of early stage mainly by established between heterogeneous device indirect communication come
Realize data exchange.Such as the method for cloud server and gateway.But these method management difficulties are big, operation expanding
It is weak, transmission delay is unpredictable, and have higher hardware device cost and maintenance cost.
Based on the above reasons, the direct communication between different technologies has more wide research for comparing indirect communication
Prospect.Therefore, wirelessly across protocol communication technology is come into being.Current across protocol communication technology mainly has and can be divided into two classes:
Layer data packet across protocol communication and physical layer across protocol communication.Layer data packet across protocol communication and physical layer across agreement
Communication.Wherein, layer data packet across protocol communication by the signal strength of modulation data packet, packet is long, transmission time and channel shape
State information realizes the information exchange between heterogeneous device.For example, WiZig is realized from WiFi to ZigBee in signal strength
Direct communication transmits information by adjusting the transmission power of WiFi equipment, and different signal strengths represents different data ratios
It is special.Gap Sense is long by adjusting the packet of data packet, realize from WiFi to ZigBee data transmission, different Bao Changke with
It is modulated into different information.FreeBee realizes the direct communication from WiFi to ZigBee from time dimension, by changing
The buoy beacon time of broadcast singal transmits information between heterogeneous device, since the beacon rate of commercial WiFi is
102.4ms/beacon, so the transmission rate of FreeBee can be also restricted because of the inherent speed of beacon.B2W2 is utilized
The variation of WiFi channel state information (Channel State Information, abbreviation CSI) realize from bluetooth equipment to
The data of WiFi equipment are transmitted.But since the data packet of transmission per second is limited, the gulping down across protocol communication of layer data packet
The amount of spitting is relatively low.
Across the protocol communication technology of physical layer be intended to allow it is compatible between heterogeneous device, can be real on physical layer signal
Now across protocol communication.For example, WEBee, which is realized with the part the payload of WiFi data packet, simulates ZigBee physical layer signal
Method so that ZigBee equipment do not need modification hardware device can recognize WiFi signal and decode.BlueBee is proposed
With Bluetooth signal simulation ZigBee signal method, physical layer realize from bluetooth to ZigBee across protocol communication.Due to object
Across the protocol communication technology of reason layer directly utilizes the signal of physical layer, thus can effectively improve rate across protocol communication and
Handling capacity.
However, the prior art is realized by the normal clock domain signal that transmitting terminal simulates receiving end across protocol communication, due to
WiFi and Zigbee protocol standard it is incompatible, along with the hardware limitation of transmitting terminal analog signal, thus simulate come when
Domain signal and the time-domain signal of standard have bigger difference.The standard of the waveform and receiving end demand that are come out due to WiFi simulation
It is not perfectly matched between time domain waveform, when practical application needs higher transmission reliability, it is necessary to it is more to repeat transmission
Secondary analogue data packet reduces so as to cause across the protocol communication efficiency and handling capacity of WiFi equipment to ZigBee equipment, so that
Communication reliability is poor.

Fig. 2 is the process signal across protocol communication method of WiFi equipment provided in an embodiment of the present invention to ZigBee equipment
Figure, as shown in Fig. 2, the embodiment of the invention provides a kind of across the protocol communication methods of WiFi equipment to ZigBee equipment, comprising:
Step 201, the target simulation phase sequence for meeting the requirement of ZigBee equipment skew is obtained；
Step 202, processing is optimized to the target simulation phase sequence, obtains ZigBee symbol and analogue phase sequence
Mapping table between column；
Step 203, simulation process is carried out according to phase sequence of the mapping table to WiFi signal, for ZigBee equipment

In embodiments of the present invention, the target simulation for meeting the requirement of ZigBee equipment skew is obtained by step 201 first
Phase sequence.WiFi equipment meets in the phase sequence that ZigBee skew changes from multiple, selects a suitable phase sequence
Column are simulated, and each phase sequence corresponds to a waveform, and WiFi equipment in payload by being partially filled in different
Hold, enables the phase sequence of payload as similar with the normalized phase sequence that ZigBee equipment needs as possible, to realize
The simulation of phase.In embodiments of the present invention, select square wave as basic waveform element, to generate a series of stairstepping
Phase sequence, and the phase of these steps phase sequences be in a decoding periods it is stable, can satisfy ZigBee
The skew of signal changes, so that WiFi equipment simulates these phase sequences by modifying the content of payload.
Then, by step 202, processing is optimized to the target simulation phase sequence, obtain ZigBee symbol and
Mapping table between analogue phase sequence, in embodiments of the present invention, through greedy algorithm from multiple analogue phase sequences, choosing
The analogue phase sequence for taking WiFi equipment simulation error smaller is as initial phase sequence.In addition, passing through analysis cyclic prefix
Adjustment is optimized to the phase value of some specific positions in influence to ZigBee.The cyclic prefix to initial phase into
After row adjustment, by feedback adjustment algorithm, according to the phase result that WiFi equipment simulates come feedback adjustment phase sequence, from
And obtain the analogue phase sequence for being suitable for WiFi equipment simulation.It is 16 corresponding since ZigBee signal has 16 symbols
Skew sequence needs 16 suitable phase sequences to simulate the skew requirement of this 16 symbols, therefore WiFi equipment is according to simulation
The smaller and decoded higher analogue phase sequence of skew result reliability of error out, constructs a symbol to phase sequence
Mapping table.Finally, simulation process is carried out according to phase sequence of the mapping table to WiFi signal according to step 203, for
ZigBee equipment is decoded WiFi signal.When needing to carry out WiFi equipment to ZigBee equipment across protocol data transmission
When, this mapping table is loaded into WiFi equipment, WiFi equipment carries out mould to corresponding phase sequence according to mapping table
It is quasi-, after ZigBee equipment receives the data packet of digital simulation, the phase sequence of simulation is decoded, to realize across association
View communication.
The embodiment of the present invention carries out analogue phase sequence by phase sequence needed for simulation ZigBee equipment decoding
Optimization processing obtains the mapping table between ZigBee symbol and analogue phase sequence, to realize that WiFi equipment is set to ZigBee
Between standby across protocol communication, improve WiFi equipment to the communication efficiency of ZigBee equipment, increase network throughput so that

On the basis of the above embodiments, the acquisition meets the target simulation phase sequence of ZigBee equipment skew requirement
Column, comprising:
It is required according to the skew of ZigBee equipment, obtains analogue phase arrangement set；
Obtain the corresponding skew sequence of every group of analogue phase sequence and standard phase partial order in the analogue phase arrangement set
Hamming distance average value between column；
Every group of Hamming distance average value is judged by greedy algorithm, it, will if judging result meets preset condition
Meet described in the corresponding analogue phase sequence conduct of Hamming distance average value of preset condition in the analogue phase arrangement set
Target simulation phase sequence.
In embodiments of the present invention, select square wave as basic waveform, to generate step-like phase sequence set, these
Phase sequence all meets the skew requirement of ZigBee equipment.Specifically, the binaryzation skew of a ZigBee symbol requires have 32
A bit, the decoding periods of each bit are 0.5us.If phase change is greater than 0, then binaryzation in a decoding periods
Skew be decoded as 1, be otherwise decoded as 0.
Fig. 3 is skew schematic diagram of the square wave provided in an embodiment of the present invention as basic waveform, as shown in figure 3, T1 to T3
Phase changed to from 0Shown in (b) in corresponding time domain waveform such as Fig. 3.Refering to what is shown in Fig. 3, τ1And τ2Two sampling instants
Meet T1≤τ1≤T2, T2≤τ2≤T3, and τ2-τ1=0.5us, corresponding skew areSo decoded binaryzation phase
It is 0, thus obtains phase sequence set of the square wave as basic waveform.
Be between the phase sequence needed due to the result and ZigBee equipment of the simulation of, WiFi equipment it is unmatched, at this
In inventive embodiments, simulation error is quantified by statistics Hamming distance.Fig. 4 provides statistics Hamming distance for the embodiment of the present invention
Schematic diagram, as shown in figure 4, the ZigBee decoded period is 0.5us, therefore, the initial time of sampled point is different, obtained phase
Partial order column are also different.Assuming that the initial time of sampling is τ1, τ2..., τ n meets in 0.5us and is uniformly distributed, then adopts in difference
Hamming distance between the sample moment skew sequence decoded and the skew sequence of ZigBee symbol is H1, H2..., Hn, at this
In inventive embodiments, statistics Hamming distance is defined as to the average value of these Hamming distances:
Wherein, n is bigger, the phase sequence that SHD, which is got over, can describe to simulate the phase sequence come and ZigBee equipment needs
Error between column.In order to guarantee the equilibrium between the complexity and experimental result that calculate, in embodiments of the present invention, n is selected
=5 parameter as SHD, the error of estimation WiFi equipment simulation.
Then, initialization process is carried out to analogue phase sequence, it is assumed that the skew sequence of ZigBee symbol are as follows:
Δ φ={ Δ φ1,Δφ2,…,Δφn, n=1,2 ..., 32；
Then corresponding phase sequence are as follows:
φ={ φ1,φ2,…,φn, n=1,2 ..., 32；
Assuming that the first phase of phase sequenceSkew between two continuous phases isThe analogue phase sequence so generated
It is classified as:
Corresponding time-domain signal are as follows:
X (n)=I (n)+Q (n)=cos (φn)+i*sin(φn), n=1,2 ..., 32；
Thus it obtains, the factor for influencing a phase sequence is first phaseSkew between two phasesFirst phase
Be selected as [0,2 π) arbitrary value, the optional range of the phase bias between two continuous phases be [0, π) arbitrary value.For letter
The problem of changing Selecting phasing, by first phaseSkew between two phasesValue carried out sliding-model control, phase sequence
It is better to arrange, and the statistics Hamming distance SHD of WiFi equipment simulation is with regard to smaller.Therefore, withFor discrete interval, by Selecting phasing problem
Be converted to the optimization problem of SHD minimum:
min SH D；
One group has been selected according to greedy algorithmSo that obtaining minimum in the value range of two parameter discretes
Statistics Hamming distance, and will be with thisThe phase sequence of generation is as initial phase sequence, i.e. target simulation phase
Sequence.
On the basis of the above embodiments, described that processing is optimized to the target simulation phase sequence, it obtains
Mapping table between ZigBee symbol and analogue phase sequence, comprising:
The cyclic prefix of the target simulation phase sequence is adjusted optimization processing, obtains the second target simulation phase
Sequence.
In embodiments of the present invention, the cyclic prefix of WiFi signal is that the time-domain signal of a part of 0.8us is copied to original
Come before 3.2us time-domain signal, such a WiFi symbol just constitutes the time-domain signal of a 4us, and ZigBee symbol
There is no such repeat property, so there can be cyclic prefix bring error with WiFi equipment simulation ZigBee.Due to one
ZigBee symbol is 16us, so needing for ZigBee symbol to be divided into 4 parts, the segment of every portion 4us all uses a WiFi symbol
To be simulated.Fig. 5 provides the schematic diagram that cyclic prefix causes simulation error for the embodiment of the present invention, as shown in figure 5, for
1/3 segment, subsequent time-domain signal is directly spliced to front by cyclic prefix, so that segment signal of front is not that ZigBee is set
Standby needs, so will appear decoding error.For the 2/4th segment, before carrying out cyclic prefix, by one section of time domain of front
Signal is substituted for the time-domain signal of aft section, and in this way after cyclic prefix, the time-domain signal of front is correct, appearance
The signal of mistake is then that subsequent section.Since ZigBee equipment is when decoding, do not go to carry out the skew at both ends
Processing, so above-mentioned flip operating method can weaken influence of the cyclic prefix to ZigBee, therefore can be by the mistake of cyclic prefix
The centre and both ends of a ZigBee symbol are accidentally assigned to, in embodiments of the present invention, the cyclic prefix of segment 1/3 is called
The cyclic prefix of segment 2/4 is called backward cyclic prefix by forward cyclic prefix.
According to the skew Δ φ for each ZigBee segment that the type of cyclic prefix and cyclic prefix are influenced1And Δ
φ7Symbol, one shares 8 kinds of different situations, as shown in table 1:
Table 1
It is adjusted by the phase to different positions, the influence of cyclic prefix can be further reduced.
In embodiments of the present invention, specific method of adjustment is with the forward cyclic prefix and Δ φ of segment 1/31=Δ
φ7For, it is assumed that the skew sequence of binaryzation is Δ φ={ Δ φ1,Δφ2..., Δ φ7}={ 1010011 }, if first
A sampled point falls in τ1It is interior, then second sampled point falls in τ3Interior, decoded result is 1.But if first sampled point
Fall in τ2It is interior, then second sampled point falls in τ4Interior, decoded result is 0, that is, decoding error occurs.Due to τ1And τ2Hold
The continuous time is respectively 0.3us and 0.2us, then the probability that mistake occurs because of cyclic prefix is 0.4.It is made to reduce cyclic prefix
At mistake, τ4Phase need be greater than τ2Phase, τ4Phase be actually original φ2, τ2Phase actually
It is φ8.So increasing original φ2So that φ2Greater than φ8, so that no matter wherefrom starting to decode, decoded result is all just
True.
On the basis of the above embodiments, it is adjusted in the cyclic prefix by the target simulation phase sequence excellent
Change processing, after obtaining the second target simulation phase sequence, comprising:
Feedback adjustment algorithm process is carried out to the second target simulation phase sequence, obtains third target simulation phase sequence
Column, to obtain the mapping table between ZigBee symbol and analogue phase sequence.
In embodiments of the present invention, in order to be further reduced the simulation error of WiFi equipment, to by greedy algorithm and following
Second target simulation phase sequence further progress feedback adjustment algorithm optimization of the optimization of ring prefix phase.Fig. 6 is the present invention
The schematic diagram for the feedback adjustment algorithm that embodiment provides, as shown in fig. 6, the phase sequence simulated according to WiFi equipment, then instead
Need phase sequence to be simulated before coming over to adjust.Specifically, in a decoding periods, the phase sequence come will be simulated
Average value as new phase value, still, in some cases, may with the skew of ZigBee itself require on the contrary, can
Refering to what is shown in Fig. 6, in (T3,T4), the average value φ of the phase sequence of WiFi equipment simulation3It is less than (T2,T3) average value
φ2.But the skew that ZigBee equipment needs is 1, in the embodiment of the present invention, directly in the phase basis of upper a cycle
Increase a Δ φ, i.e. φ '3=φ2+ Δ φ, so that the optimization of feedback adjustment algorithm is completed, so that WiFi equipment simulated
The application condition of phase sequence is small, to realize WiFi equipment to ZigBee equipment across protocol communication.Meanwhile it being adjusted according to feedback
Third target simulation phase sequence after whole algorithm optimization, WiFi equipment obtain between ZigBee symbol and analogue phase sequence
Mapping table.
On the basis of the above embodiments, described to be carried out at simulation according to phase sequence of the mapping table to WiFi signal
Reason, so that ZigBee equipment is decoded WiFi signal, comprising:
The payload of WiFi signal is constructed, according to the mapping table so that ZigBee equipment simulates the payload
ZigBee signal phase sequence be decoded.
On the basis of the above embodiments, since a phase sequence corresponds to a time domain waveform, by this time domain wave
Shape is put into the FFT module of WiFi equipment, obtains FFT coefficient.In addition, the subcarrier of WiFi signal and ZigBee signal overlap has
7, select the phase sequence that ZigBee is simulated on 7 subcarriers of this overlapping.According to ZigBee symbol and analogue phase sequence
Mapping table between column, on the planisphere of WiFi64QAM, selection corresponds to the most similar QAM of FFT coefficient with 7 subcarriers
It puts to construct the payload of WiFi signal.The other parts such as preamble, header and tail due to WiFi are all and common
The data packet of WiFi signal is the same, and therefore, this data packet is still able to be received by WiFi equipment.When the receiving end of ZigBee
After receiving such data packet, the other parts such as preamble, header and the tail of WiFi are neglected, only to payload
The phase sequence come is simulated to be decoded.To realize WiFi equipment to ZigBee equipment across protocol communication.
On the basis of the above embodiments, the correspondence waveform of the target simulation phase sequence is square wave.
In embodiments of the present invention, in order to guarantee that phase is stable in a decoding periods, selects square wave as one
A basic unit generates phase sequence and corresponding waveform.It should be noted that, although the high fdrequency component of square wave is greater than sine
The high fdrequency component of wave, but also can be with 7 subcarriers of WiFi equipment come analogue phase sequence.This is because binaryzation phase partial order
Some continuous 0 or 1 are shown, so the phase sequence generated is step-like.Due to the frequency component of stairstepping sequence
Concentrate within 2M, thus with WiFi signal and the 2M bandwidth of ZigBee signal overlap come the phase sequence of analogue step be close
Reason, stability with higher.
