Specific embodiment
The invention discloses the data transmission method that a kind of server and terminal are communicated, which is also
A kind of transport protocol, comprising:
Message is grouped as by header part, data portion, packet tail portion, and the format of header part and packet portion is fixed, number
It can be changed according to part, data portion is enclosed between header part and packet portion, using fixed format and changes content
Mode is conducive to development efficiency.
Header part includes identification head, data number of segment, packet length, these are the essential informations of message.
Packet portion includes sequence number, check bit and stop position, is identification, the content wrong identification of message respectively
And the end position of message.
Data portion can be made of one or more data segment, and multiple data segments are packaged in transmission in a message,
It improves efficiency.
All messages package in the following way in the present invention:
Such as:
The present invention is considering high-mechanic in design, each bit can represent a kind of state, and a byte can
To indicate 8 kinds of states.And character protocols need one byte representation one, 8 kinds of states need 8 bytes.Under specific circumstances,
This agreement is 1/8 size of character protocols.
Such as:
The present invention also has the characteristics that high availability: comparing intelligence by byte transmission, ASCII can be read with step-by-step, without symbol
Numbers 8, have symbol 8, UCS2, Unicode can also be read by double byte and is used to transmit Chinese or other non-ascii characters.
With ASCII protocol comparative examples:
ASCII protocol length is the location information packet of 193 bytes:
[3G*861358031672967*00A7*UD,090718,220658,C,0.000000,N,0.000000,W,
0.000,0.000,0.000,0,21,87,0,0,00000020,5,0,460,00,9771,5023,96,9771,5024,96,
9771,4043,102,9771,4041,103,9771,3921,104,0,2000.0], changing corresponding binary protocol into indicates,
Length is 63, and it is long by 126 to be converted to ASCII display, actual storage length 130 byte fewer than simple ASCII protocol, almost
The 1/3:d1d1003ac1018033070460008270382061898600621916071664 700d58515 of ASCII length
f4f5447385f56312e3030032c2c012c03d8010000000014007800000002780d0d。
The penultimate of message is check bit, and the verification of correctness wrapped when unpacking is protected by built-in check bit
Demonstrate,prove the accuracy in data transmission procedure.
It multiple data segments, each data segment contents format can about fix in this agreement side by side inside one message
Formula.Such as:
Log in packet OXO1.......................
State packet OXO3.......................
Position data combination packet OXO5.........
Device parameter and event notify OXCO..
In line OXC1...................
File download OXFD...................
Transmitting file OXFB............ in terminal
Inside one position grouping packet, GPS location packet, the position LBS packet, the position WIFI packet may include.It is reported by one
Text may include multiple data portions, improve efficiency of transmission.
It is which bag data sent after device power-up that sequence number, which is used to identify this bag data, can pass through the company of sequence number
Continuous property analyzes the general work state of setting.Under normal circumstances, restart within equipment every 24 hours primary, the number of upload in every 20 seconds
According to 24 hours 4320 bag datas of upload, the maximum value of double byte is 65535, and using low 13, maximum length is expressed as 8191.
This length sends maximum data considerably beyond the odd-numbered day.3 represent encrypted state before the high byte of sequence number, this agreement supports 3-
Des encryption and AES encryption, encryption only have progress to data segment.
No. 01 agreement is to log in packet, contains equipment general information logging in packet, this information and network mark after login
Know SocketID to be bound, subsequent packet no longer uploading device information, achievees the purpose that reduce packet length.
In the present invention, increasing data number of segment in packet length indicates: by mass data the study found that mobile network
Sending and receiving data amount list wraps limit in 1300 bytes or so, and 2Bytes maximum value is 65535, considerably beyond single packet length upper limit,
So being changed to low 11 to indicate data packet length, maximum value 2048.And high 5 are used to indicate the data packet of data segment portion
Number, maximum value 31 is not in so many data packet in use.
Data transmission method of the invention is not only able to improve development efficiency, and improves efficiency of transmission, and data
The safety of transmission is ensured.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
