</SEND>), many-one is (at one<cOMM></COMM>it is a plurality of in combination<rECEIVE>...</RECEIVE>it is one corresponding
<sEND>...</SEND>) or multi-to-multi (at one<cOMM></COMM>it is a plurality of in combination<rECEIVE>...</
RECEIVE>correspondence is a plurality of<sEND>...</SEND>), a hair one receipts, a multiple receipts, multicast or multiple may be implemented
That receives freely configures more.
It is configured by XML file, diagnostic techniques personnel may be replicated, and pastes and replaces, configuration data side
Just, high-efficient, and scalability is strong.
Preferably, computer 110 is matched from configuration file according to diagnostic instruction, corresponding return instruction is found,
And the return instruction is sent to simulator 120 and further comprises:
If diagnostic instruction A, in configuration file does not use mask XX and substitution symbol?, then when computer 110 receives
To diagnostic instruction and configuration file in diagnostic instruction it is completely the same when, successful match finds corresponding return instruction, and will
The return instruction is sent to simulator 120.
If having mask XX in diagnostic instruction B, in configuration file, other data other than mask XX are matched
When, successful match finds corresponding return instruction, judges whether there is mask XX in return instruction, if it is not, then referring to the return
Order is sent to simulator 120, if so, the data for corresponding to mask XX in diagnostic instruction that computer 110 receives are replaced
Mask XX in return instruction, then replaced return instruction is sent to simulator 120.
It is specific for most of agreement by mask XX come the specific data of alternate variation in diagnostic instruction
Data be followed by the number increase of transmission and can also change, such as the agreement that comings producer uses requests phase every time
Same function, will directly occur to change accordingly！CCP agreement is even more so, from successively alternately becoming between 00-FF
Change, the not support of mask, can not be completed entire diagnosis process.Here is one section of CCP protocol massages of interception:
CCP protocol massages
Using mask XX come the specified byte of alternate variation, can guarantee in this way data transmit-receive can flexibility, guarantee to examine
Disconnected continuity, when computer 110 receives the diagnostic instruction from vehicle diagnostic equipment 130 sent from simulator 120
Afterwards, when being matched from configuration file by the diagnostic instruction, without comparing whether mask XX matches, mask XX need to only be met
Other Data Matchings in addition, then be sent to simulator 120 for corresponding return instruction.
When carrying out data flow diagnostic function, the number in diagnostic instruction and return instruction can also be realized using mask XX
According to being replaced simultaneously, i.e., in configuration file, mask XX is used in diagnostic instruction and return instruction simultaneously.To configure as follows
For file:
< COMM >
21 00 00 00 00 < of F1 XX of < RECEIVE > 18DA17F0:03/RECEIVE >
14 61 F1 XX 23 23 23 21 23 23 23 23 23 23 of < SEND > 18EAF017:10</SENID>
</COMM >,
In matching, if computer 110 receives, XX in configuration file is corresponded in diagnostic instruction is 00, and return is referred to
XX in order replaces with 00, is then forwarded to simulator 120, can guarantee that data loading capacity is most under identical address in this way
Few.
If having substitution symbol in diagnostic instruction C, in configuration file?, then when substitution accords with? equal of other data in addition
Timing, successful match find corresponding return instruction, and the return instruction are sent to simulator 120.
When progress ECU writes with a brush dipped in Chinese ink the Simulation Diagnosis function with upload, needs matched data volume very big, K line is communicated
For, maximum amount of data is FF (256) a byte, it is impossible to 256 bytes is filled in XML file, as 256 during writing with a brush dipped in Chinese ink
The quantity of a byte has wraps more at least 100, and the data volume of each packet is different, needs to meet above functions, less again
Do the number of input, the present invention pass through substitution symbol in diagnostic instruction and return instruction? indicate not needing matched data,
Need in matching, it only match substitution symbol? several data before, by taking following configuration file as an example:
< RECEIVE > 00 21 36? </RECEIVE >,
In matching, when front three is 002136 in the diagnostic instruction that computer 110 receives, as successful match,
And then find corresponding return instruction.The data volume for greatly reducing XML text in this way supports the simulation of big data.
In the present embodiment, pin, baud rate, communication modes, diagnostic instruction and the configuration of corresponding return instruction are same
In one XML file:
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
