Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
Example one
As shown in fig. 1, the encoding method of a remote data transmission protocol provided in this embodiment includes:
step S11, acquiring all fields of a first line of coded content, carrying out ASCII code conversion on the fields according to the sequence from left to right to obtain field character strings corresponding to each field, and forming all the field character strings into line character strings of the first line, wherein 0x01 characters are used as intervals between every two adjacent field character strings in the line character strings of the first line, 0x02 characters are arranged at the tail of the line character strings of the first line, and the line character strings of the first line are used as temporary character strings;
and step S12, acquiring the next line of fields of the coded content, coding to obtain the next line of line character strings, adding the next line of line character strings to the temporary character strings until the fields of all lines of the coded content are coded, and sending the finally obtained temporary character strings as SelectHelp data.
In step S12, the method for obtaining the next row character string of the next row by obtaining the next row field of the encoded content and encoding is the same as the method in step S11, and is not described herein again.
The selecthellp data is an aggregate of data queries or data packets, the selecthellp data is organized according to rows and columns, for example, the data in table 1 includes rows and columns, and the specific form of the selecthellp data obtained after conversion is detailed in the following specific steps. Generally, in the field of industrial internet of things, the first row of the SelectHelp data includes names (such as "number", "current temperature", "current location", and "fault number" in table 1), and data corresponding to the respective names (such as "10", "23.4", "a 01", and "11" in table 1) starts from the second row.
In the process of exchanging service data of the industrial ethernet, there are basically no special characters such as 0x01 and 0x02, so the remote data transmission protocol of this embodiment uses 0x01 characters as separators between fields, and uses 0x02 characters to separate rows. Therefore, after the field is converted to ASCII code, the 0x01, 0x02 characters cannot appear. The length and the number of the fields are not limited, the fields can be increased at will without affecting the original data, and the future protocol extension is facilitated.
The protocol frame format of the remote data transmission protocol in this implementation has the following features:
1) coding format
All communication packets are composed of ACSII code characters.
2) The data packets are displayed in rows and columns to form tabular data.
As shown in table 1, the first row shows the specific column names of the data and the second layer begins to represent the values of the specific each row. Wherein, the "number", "current temperature", "current position", "fault number" are the fields of the first row; "10", "23.4", "A01", "11" are fields of the second row.
TABLE 1
| Numbering | Current temperature | Current temperature | Fault number |
| 10 | 23.4 | A01 | 11 |
Taking the data in table 1 as an example, the encoding is performed as follows:
step one, acquiring all fields of a first line of encoded content: "number", "current temperature", "current position", "failure number"; and carrying out ASCII code conversion on the fields in the sequence from left to right to obtain a field character string corresponding to each field, such as: the field string corresponding to the field "number" after conversion is "0 x7f 0x160x 530 xf 7", the field string corresponding to the field "current temperature" after conversion is "0 x5f 0x 530 x 520 x4d 0x6e 0x290x5e 0xa 6", the field string corresponding to the field "current position" after conversion is "0 x5f 0x 530 x 520 x4d 0x4f 0x4d 0x7f 0x6 e", the field string corresponding to the field "fault number" after conversion is "0 x 650 x 450 x 960 x9c 0x 530 xf 7"; the line string that groups all field strings into the first line is "0 x7f 0x160x 530 xf70x01 0x5f 0x53 0x52 0x4d 0x6e 0x29 0x5e 0xa6 0x01 0x5f 0x53 0x52 0x4d 0x4f 0x4d 0x7f 0x6e 0x01 0x65 0x45 0x96 0x9c 0x53 0xf70x02", where every two adjacent field strings are separated by 0x01 characters and the line string ends with 0x02 characters; the line character string of the first line is taken as a temporary character string. Wherein, the 0x01 and 0x02 are underlined to clearly show the positions of the separators 0x01 and 0x02, and there is no format in the actual encoding process.
Step two, all fields of a second line of the encoded content are acquired: "10", "23.4", "A01", "11"; enter fields in left-to-right orderEach corresponding field character string is obtained by line ASCII code conversion, the corresponding field character string after the conversion of the field "10" is "0 x 310 x 30", the corresponding field character string after the conversion of the field "23.4" is "0 x 320 x 330 x2e 0x 34", the corresponding field character string after the conversion of the field "A01" is "0 x 410 x 300 x 31", and the corresponding field character string after the conversion of the field "11" is "0 x 310 x 31"; the line string that groups all field strings into the second line is "0 x 310 x300x01 0x32 0x33 0x2e 0x340x01 0x41 0x30 0x31 0x01 0x31 0x31 0x02", where every two adjacent field strings are separated by 0x01 characters and the line string ends with 0x02 characters; after the line string of the second line is added to the temporary string, a new temporary string of "0 x7f 0x160x 530 xf7 is obtained0x01 0x5f 0x53 0x52 0x4d 0x6e 0x29 0x5e 0xa60x01 0x5f 0x53 0x52 0x4d 0x4f 0x4d 0x7f 0x6e 0x010x65 0x45 0x96 0x9c 0x53 0xf70x020 x31 0x30 0x01 0x32 0x33 0x2e 0x34 0x01 0x41 0x30 0x310x01 0x31 0x31 0x02”。
Since only two rows of data are listed in table 1, the temporary character string obtained in step two is the finally obtained temporary character string, and the finally obtained temporary character string is sent as selecthellp data.
In the actual use process, the data is far more than two lines, and only the fields in the next line of the coded content need to be continuously obtained and coded according to the method until the fields in all the lines are coded, and finally the obtained temporary character string is used as the SelectHelp data to be sent. The encoding manner for each row is similar, and is not described herein again.
The encoding method of the remote data transmission protocol provided by the embodiment has the advantages of simple encoding mode and high transmission rate, can encode fields in any form, is suitable for data transmission among devices in the field of industrial internet of things, unifies protocol formats of the devices during data interaction, reduces access workload, and is beneficial to improving the integration efficiency of the industrial internet of things system.
When the field is converted into ASCII code, in order to prevent the occurrence of 0x01 characters after conversion and collision with the delimiter, special processing needs to be performed on the field, and therefore, a specific process of performing ASCII code conversion on the field to obtain a field character string includes: carrying out ASCII code conversion on the field to obtain a first character string; if the first character string does not contain 0x01 characters and 0x02 characters, the first character string is taken as a field character string of the field; if the field after the ASCII code conversion contains 0x01 characters or 0x02 characters, the field is converted into base64 characters, and the base64 characters are converted into a field character string by the ASCII code conversion.
Example two
Based on the same inventive concept as the encoding method, the present embodiment provides a decoding method of a remote data transmission protocol, as shown in fig. 2, including:
in step S21, SelectHelp data is received.
In step S22, the row coordinate and the column coordinate of the memory address are both set to 0. This is the memory address initialization step.
Step S23, reading the character in the SelectHelp data, and if the character is not 0x01 and the character is not 0x02, storing the character in a second character string; if the character is 0x01, converting the second character string into text data and storing the text data in a storage address, and adding 1 to the column coordinate of the storage address; if the character is 0x02, the second character string is converted into text data and stored in the memory address, the row coordinate of the memory address is added with 1, and the column coordinate of the memory address is changed to 0.
Step S24, judging whether the character is the last character of the SelectHelp data, if not, returning to step S23, reading the next character in the SelectHelp data, and performing character conversion; if the character is the last character, the decoding is finished.
Still taking the data in table 1 as an example, the decoding process is as follows:
the SelectHelp data sent by the receiving encoding end is' 0x7f 0x160x 530 xf70x01 0x5f 0x53 0x52 0x4d 0x6e 0x29 0x5e 0xa60x01 0x5f 0x53 0x52 0x4d 0x4f 0x4d 0x7f 0x6e 0x01 0x65 0x45 0x96 0x9c 0x53 0xf70x020x31 0x30 0x01 0x32 0x33 0x2e 0x340x01 0x41 0x30 0x31 0x01 0x31 0x31 0x02", the coordinates of the memory address at this time are (0, 0).
Reading the first character in the selecthell data as "0 x7 f" instead of 0x01 and 0x02, reading the second character string2 as "0 x7 f", reading the second character "0 x 16", reading string2 as "0 x7f 0x 16", reading the third character "0 x 53", reading string2 as "0 x7f 0x160x 53", reading the fourth character "0 xf 7", reading string2 as "0 x7f 0x160x 530 xf 7", reading the fifth character as "0 x 01", at this time, transcoding the string2 to obtain the text data as "number", storing as the storage address of (0,0) (i.e. the position of the first row in table 1), and adding 1 to the column coordinate of the storage address, at this time, the storage address of (0,1), and string 2. Reading the next character in the selectHelp data continuously, storing the character into string2 until the next '0 x 01' is met, transcoding string2 to '0 x5f 0x 530 x 520 x4d 0x6e 0x290x5e 0xa 6' to obtain the text data as the 'current temperature', storing the text data according to the storage address of (0,1) (namely the position of the first row and the first column in the table 1), adding 1 to the column coordinate of the storage address, wherein the storage address is (0,2) at this moment, and emptying string 2. And continuously reading characters in the SelectHelp data, and obtaining that the text data with the storage address of (0,2) is the current position and the text data with the storage address of (0,3) is the fault number according to the steps. When the read character is "0 x 02", the row coordinate of the storage address is added with 1, and the column coordinate of the storage address is 0, then the storage address is changed to (1, 0) clear string2, so that the contents of the first row are all decoded. Decoding of the second row is performed as described above, eventually reducing all of the contents of table 1.
The decoding method of the remote data transmission protocol provided by the embodiment can improve the data transmission rate by matching with the coding method, unify the protocol format of the devices during data interaction, reduce the access workload and contribute to improving the integration efficiency of the industrial Internet of things system.
In order to detect the integrity of the received protocol, the decoding process further comprises: judging whether the number of the fields in each row is consistent, if not, representing that the data format is invalid, and the specific implementation mode is as follows: and judging whether the maximum column coordinates of the storage addresses of each row are consistent or not, and if not, marking the SelectHelp data as invalid data.
