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 are obtained all without creative efforts
Other embodiments shall fall within the protection scope of the present invention.
First aspect of the embodiment of the present invention provides a kind of data transmission method, shown in Figure 1, is provided by the invention
A kind of flow chart of a preferred embodiment of data transmission method, the method are executed by transmitting terminal；The method includes steps
Rapid S11 to step S15:
Step S11, synchronizing sequence is generated according to preset length difference sequence criteria；Wherein, if the synchronizing sequence by
Dry synchronization packets composition.
Transmitting terminal generates synchronizing sequence according to pre-set length difference sequence criteria, and synchronizing sequence is not a data
Packet, but the sequence collectively constituted by several synchronization packets, two neighboring synchronization packets in synchronizing sequence
Length difference correspondence meets above-mentioned length difference sequence criteria.
Above-mentioned length difference sequence criteria is that transmitting terminal and receiving end are arranged jointly, and there may be multiple WIFI in environment
Equipment, each WIFI equipment can send data packet, and audiomonitor, that is, receiving end is by the method for identification synchronizing sequence in crowd
Itself desired data packet is identified in more data packets, as long as the length difference sequence criteria that transmitting terminal is arranged according to this is gone
Synchronizing sequence is constructed, whether the anterior-posterior length difference for the data packet that receiving end relatively receives meets above-mentioned length difference sequence criteria
Synchronizing sequence can be identified, to realize that receiving end is synchronous with the data transmission and reception of transmitting terminal consistent.
For example, it is 2, -2 that the length difference sequence criteria that synchronizing sequence needs to meet is arranged in transmitting terminal and receiving end jointly,
2, -1,1, then synchronizing sequence is made of six synchronization packets, the length of first synchronization packets and second synchronization packets
Degree difference is 2 (length that the length of previous synchronization packets subtracts the latter synchronization packets), second synchronization packets
Length difference with third synchronization packets is -2, the length difference of third synchronization packets and the 4th synchronization packets
Be 2, the length difference of the 4th synchronization packets and the 5th synchronization packets is -1, the 5th synchronization packets with the 6th
The length difference of synchronization packets is 1.
It should be noted that the length of the synchronization packets in synchronizing sequence it is different establish a capital it is identical, as long as meeting above-mentioned length
Sequence of differences standard is spent, however, it is desirable to ensure that the length of synchronization packets cannot be with the length weight of the data of actual transmissions
It is folded, such as the length of synchronization packets can be limited in a specific length range.
Step S12, the first datum length of the first reference data packet is determined according to the length of the synchronization packets.
Transmitting terminal can be determined according to the length of the synchronization packets in synchronizing sequence and be sent after generating synchronizing sequence
First datum length of the first reference data packet at end, such as made with the maximum length value of synchronization packets or minimum length value
For the first datum length of the first reference data packet.
Step S13, data to be sent are grouped, each group of data correspondence are encoded into a group data packet, and be
Each group allocation of packets group mark；Wherein, the length difference of the length of each group data packet and first datum length
The group offset information of the corresponding primary data information (pdi) of this group of data packet and initial data is carried in value；Described group be identified as it is default
The identification data packet of length.
Transmitting terminal during carrying out data transmission, may due to the data packet of other modules transmission problem or
The parsing problem of receiving end and lead to data entanglement to be sent, the embodiment of the present invention is using being grouped coding to data to be sent
And the mode for being grouped transmission is transmitted, and according to the group leader of agreement, data to be sent are divided into specific group number, then by each group of number
Be encoded into a group data packet according to corresponding, and be each group allocation of packets group mark, send each group data packet it
Before, corresponding group of mark of this group of data packet is first sent, for the ease of identification, group mark can be identified by length value, with
The identification data packet of preset length is as group mark, and corresponding group of mark of each group of data is different, i.e. each mark number
It is different according to the length of packet, however, it is desirable to ensure that the length of identification data packet cannot be with the length and actual transmissions of synchronization packets
Data length overlapping.
By the method to data packet transfer to be sent, the influence of single error data can be controlled in grouping range
It is interior, reduce the influence for the correctness that individual data mistake is transmitted overall data and parsed.
Specifically by each group of data are corresponding be encoded into a data packet when, in order to guarantee data transmission and parsing in group
Correctness needs to encode the primary data information (pdi) of this group of data into the length and above-mentioned first base value in corresponding group of data packet
In length difference according to the first datum length of packet, and need group of the initial data of this group of data in this group of data is inclined
It moves information also to encode in length difference, i.e., contains group offset information and primary data information (pdi) in length difference, for example, can be with
Agreement indicates the group offset information of initial data using specific bit position, and specific bit position indicates primary data information (pdi).
It should be noted that the group offset information of initial data refers to location information of the initial data in affiliated group,
For example, position of some initial data in a certain group of data in this group of data is second position, then its location information 2
Coding is also required in length difference as a group offset information.
Step S14, the synchronizing sequence, all identification data packets and all group data packets are preset according to first suitable
Sequence is integrated into data packet to be sent.
After the completion of data packet coding to be sent, transmitting terminal is by the synchronizing sequence of generation, all group identification data packets
With all group data packets according to pre-set sequence integration at data packet to be sent, for example, according to " synchronizing sequence, first
A group of identification data packet, first group data packet, second group identification data packet, second group data packet,
The sequence integration of the last one group identification data packet, the last one group data packet " is at data packet to be sent.
Step S15, the data packet to be sent is cycled through, until the stopping transmission information for receiving receiving end return is
Only.
Above-mentioned data packet to be sent is cycled through according to the sequence of above-mentioned integration, the data packet sent in circulation each time is complete
It is exactly the same, until the stopping for receiving receiving end return sends information.
It should be noted that the mechanism embodiment of the present invention for stopping circulation connecing without reference to, it may be possible to receiving end all
It harvests into notice transmitting terminal later to stop sending data packet, it is also possible to which the mechanism for needing more top in different application scenarios is come
Notice stops sending, such as the embodiment of the present invention then connects upper front end in receiving end for configuring receiving end connection front end SSID
Afterwards, and after ensuring veritably establish its communication with transmitting terminal, transmitting terminal can be notified to stop sending.
A kind of data transmission method provided by the embodiment of the present invention, it is first determined the benchmark of a reference data packet is long
Degree causes the length for the data packet for carrying identical information sending out even if the cipher mode that transmitting terminal and receiving end use is not identical
The absolute value of sending end and receiving end is inconsistent, but the reference data packet of the length of data packet and receiving end that parses of receiving end
The datum length of the reference data packet of the length and transmitting terminal for the data packet that the length difference and transmitting terminal of datum length are sent
Length difference is consistent, and transmitting terminal is carrying out coding acquisition group data packet to each group of data by carrying initial data
In the length difference of the datum length of the reference data packet of length and transmitting terminal, receiving end is passed through to the number received
It is decoded acquisition initial data according to the length difference of the datum length of the reference data packet of the length and receiving end of packet, so as to
The data parsing due to caused by the inconsistent bring data length of cipher mode is inconsistent of transmitting terminal and receiving end is enough solved to ask
It inscribes, and guarantees the correctness and reliability of data transmission by way of being grouped coding to data to be sent.
It should be added that the base of the reference data packet of the datum length and receiving end of the reference data packet of transmitting terminal
Standard length may not be identical, different situation be transmission reference data packet data (may be considered IP packet) pass through it is other
SSID forwarding after WIFI packet (packet radio for carrying above-mentioned IP packet) be another wrap, length may be due to cipher mode
Difference cause the WIFI packet for carrying the IP packet with transmitting terminal not identical, as can guarantee that the identical reason of length difference exists
Be in the length difference that an IP packet is carried by the WIFI packet encrypted and is carried by the WIFI packet of no encryption it is fixed, this is
It is determined by the Encryption Algorithm of WIFI, for example, it is assumed that transmitting terminal use, without encryption, receiving end uses AES encryption, is carried at both ends
The long difference of the packet of the WIFI packet of the same IP packet is 20, therefore the packet of reference data packet and the real WIFI packet for carrying data is long
Difference at both ends must be equal.
As an improvement of the above scheme, the method also includes:
The data to be sent are tested and calculated, the first check code of the data to be sent is obtained；Then,
It is described that the synchronizing sequence, all identification data packets and all group data packets is whole according to the first preset order

Two preset orders are integrated into data packet to be sent.
Specifically, transmitting terminal is verified and calculated to data to be sent in conjunction with above-described embodiment, data to be sent are obtained
Corresponding first check code, and by the synchronizing sequence of generation, the first check code, all group identification data packets and all groups
Data packet according to pre-set sequence integration at data packet to be sent, for example, according to " synchronizing sequence, the first check code, first
A group of identification data packet, first group data packet, second group identification data packet, second group data packet,
The sequence integration of the last one group identification data packet, the last one group data packet " at data packet to be sent and is sent, so that
The data that receiving end can be received according to the first verification code check received.
A kind of data transmission method provided by the embodiment of the present invention, by first transmitting number to be sent before data is transmitted
According to check code thereby may be ensured that the correctness and integrality of data so as to receiving end verify data when receiving data.
