Data application layer and communication interface are this type of communication program modular design methods that arrives commonly used.And, general just subsidiary packing and the parsing that has realized agreement of communication interface, this also is agreement change or expansion, a main cause that causes the modification of program difficulty to strengthen.In the present invention, protocol packing with resolve individual processing, and the command script of writing based on the XML data interchange file, it is simply clear to make between the program module, protocol extension reduces the program maintenance difficulty, even needn't update routine, and only add command script and get final product.
Fig. 4 illustrates the schematic diagram that the concrete processing of communications protocol is realized in command script storehouse that instruction parser among Fig. 3 and XML mode represent.
Instruction parser is under the situation that receives the instruction that sends from data application layer, searching the command script of and instruction correspondence in the command script storehouse that the ML of institute mode is represented comes instruction is packed, and the result that will pack sends to communication interface, and instruction parser unpacks protocol data receiving after the protocol data that communication interface returns, and it is returned to data application layer.
The command script that the XML data interchange file is write comprises the description of heading, the description of instruction and the description of parameter.Wherein, instruction comprises and class instruction is set and question and answer mode instructs; And parameter comprises the following parameter that sends instructions and the parameter of return data.
Instruction parser obtains heading, instruction, parameter respectively by the operation to the XML data file, then according to the synthetic message of the description of instruction.Simultaneously, receive the data that communication interface returns, according to the analysis mode of instruction description, data are resolved then.Give data application layer the result at last.
Be elaborated below in conjunction with a specific embodiment, so that purpose of the present invention, technical scheme and advantage are had more deep understanding.
At first, consider the message body of a simple communications protocol, as shown in the table:
Instruction comprises as giving an order:
1. channel frequence order (0x1000) is set
Parameter format:
Number of active lanes (2) | channel number (2), centre frequency (4) | channel number (2), centre frequency (4) | ...
Parameter declaration:
Channel number: the channel number number of carrying frequency, scope 1～40;
Centre frequency: with MHz is unit, rounds numerical value.
The instruction nothing is returned.
2. inquiry channel frequence order (0x2000)
Parameter format:
Number of active lanes (2) | channel number (2) | channel number (2) | ....
Parameter declaration:
Channel number: the channel number number of carrying frequency, scope 1～40.
Number of active lanes: value 0, all passages of expression inquiry, otherwise value 1～40.
Operation is returned:
Number of active lanes (2) | channel number (2), centre frequency (4) | channel number (2), centre frequency (4) | ...
Its concrete implementation step is described as follows:
At first, analyze communications protocol, extract the general character of communications protocol.This agreement is easy to distinguish parts such as heading, instruction, parameter.Heading is made up of 5 parts, is respectively: destination address, source address, command code, packets of information are grown, are kept, and have stipulated the word length of each several part.The parameter of instruction is along with the number of active lanes of inquiry or setting is inconsistent, and length is variable.
Then, the instruction of communications protocol heading, message, message parameter are carried out abstract, and can describe by the XML file.
At the present invention, heading can be described below:
<commhead>
<aim?len＝”4”>1234</aim>
<source?len＝”4”>4321</source>
<command>2</command>
<param>4</param>
<reserve>2</reserve>
</commhead>
Description herein can be very flexible, and field name can oneself define, but must be mapped one by one with the field of instruction parser the inside.Processing is Mr.'s cost script, does instruction parser again.
In the description of above-mentioned XML file,＜aim len=" 4 " 1234＜/aim〉represent that the destination address of heading is 1234, take 4 bytes in the message the inside.If destination address is uncertain, then need to distinguish, for example can be filled into 1234 position with NULL, to pass to instruction parser to destination address in the place that application layer is called.The source field description source address situation.Command/param/reserve has described the word length of counterpart in the heading the inside respectively.
Message instruction can be synthesized with parameter and is described below:
＜command code=" 0x1000 " name=" the channel frequence order is set "
<return>false</return>
<channel?num＝”2”len＝”2，4”>
<param>1，1961</param>
<param>10，1962</param>
</channel>
</command>
Mentioned order has been described the order 0x1000 that channel frequence is set, and has described code, command name, and the return item has been described order and do not returned, it is 2 that the channel item has been described port number, len represents first of parameter, and channel number accounts for 2 bytes in buffering area, and 4 expression frequencies account for 4 bytes.Param is concrete parameter.In addition, also need the unfixed situation of processing parameter, for example, the frequency of passage is set, may be relevant with user's selection, when application layer is called this instruction 0x1000 so, need import concrete parameter come in into, replace the fixed value of param the inside or revise the value of param the inside.
Describe from above-mentioned XML, field name can be more random, as long as be convenient to read, command description known get final product.
Next, write command process module, that is, and instruction parser.The whole process of writing instruction parser is exactly the processing XML file basically.For example, command process module is exposed to data application layer interface CallCommand (), 2 parameters of interface band, (char*pszCode, char*pszParam).Wherein pszCode illustrates the instruction of calling, and pszParam illustrates the param parameter of this instruction.If pszParam is empty, then represent to get parameter from XML script the inside.Then this interface can form the protocol data bag in the following manner:
1. protocol data buffering area → filling destination address buffering area → filling source address → filling pszCode → empty 4 bytes (parameter length) → empty 2 bytes are set to be kept.
2. if search the parameter of the corresponding pszCode of XML script file → read → read XML script file param item → call pszParam parameter is arranged, then fill; Otherwise fill the parameter that XML script file param item forms → parameter length is filled into the parameter length of step 1 → parameter is added to protocol data buffering area back → submissions communication interface transmission of step 1.
3. resolve the instruction of returning.Consider instruction 0x2000.
＜command code=" 0x2000 " name=" order of inquiry channel frequence "
<return>true</return>
<channel?num＝”3”len＝”2”>
<param>1</param>
<param>10</param>
<param>13</param>
</channel>
<result>2，4</result>
</command>
Notice that the value of return has changed true into, represents can receive response after this instruction issues.If do not receive, that must be network or the other side's mistake.In addition, the result item has been stipulated the protocol package returned, remove heading after, the analysis mode of the parameter of back: 2 byte lanes number, 4 byte frequency values ....A plurality of values of one group [2 byte lanes, 4 byte frequencies] have so just been formed.Return to data application layer, thereby finish parsing.
At last, carry out agreement expansion or modification.The protocol resolver in the 3rd step can not be revised in suitable processing, only needs to revise or add to instruct the XML script file.For example, inquiry ambient temperature.Only needing the XML script file to add an instruction gets final product:
＜command code=" 0x3000 " name=" the inquiry ambient temperature "
<return>true</return>
<channel?num＝”1”len＝”2”>
<param>1</param>
</channel>
<result>2</result>
</command>
Data application layer is when calling interface CallCommand, protocol resolver scanning XML scripting documents forms protocol package according to designated parameters, sends by communication interface, the data of returning by the analysis mode that should instruct is handled data, return to data application layer more then.
In the present embodiment, owing to adopted the mode of XML data interchange file to realize communications protocol, only need editor XML command script file, can realize packing and parsing rapidly to instruction, reduce the design difficulty and the maintenance difficulties of code greatly, under protocol suite is not very huge situation, tangible technical advantage is arranged.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
