Foreground program takes out the V1 of version number in the message after receiving backstage transmission message A, gets the V2 of version number on foreground oneself own again, relatively two version numbers;
If V1 and V2 are same versions, then the pairing message blocks of V1 version is handled in the message body of foreground program taking-up message A;
If V1 is newer than V2 version, takes out message A institute and can compatible version number tabulate;
If V2 just in tabulation, then handle in the message body of foreground program taking-up message A, otherwise just abandon by the pairing message blocks of V2 version;
If V2 is newer than V1 version, then foreground taking-up itself can be compatible version list;
If V1 in version list, then the pairing message blocks of message A version V1 is handled to foreground program, otherwise message just abandons.
Flow process through above under the different situation of the version on foreground version and backstage, still can guarantee normally carrying out of Message Processing, just can not influence the normal operation of system because of the difference of AM/BAM software version.
Fig. 6 is the flow chart that the foreground equipment sending message arrives background process in the embodiment of the invention.
Program on the hardware device of foreground is sent out message B (version V3) by Ethernet and is given the background computer system;
The backstage message processing program receives message B;
The backstage message processing program takes out the command code among the message B, according to the difference of command code, message is sent to the corresponding background program;
Background program takes out the V3 of version number among the message B after receiving foreground transmission message B, gets the V4 of version number on backstage own again, relatively two version numbers;
If V3 and V4 just are same versions, the pairing message blocks of V3 version is handled in the message body of background program taking-up message B;
If V3 is newer than V4 version, takes out message B institute and can compatible version number tabulate;
If V4 just in tabulation, then handle in the message body of background program taking-up message B, otherwise just abandon by the pairing message blocks of V4 version;
If newer version is V4, then background program taking-up itself can be compatible version list;
If V3 is in version list, then the pairing message blocks of background program taking-up message B version V3 is handled, otherwise message just abandons.
Flow process through above under the different situation of the version on foreground version and backstage, still can guarantee normally carrying out of Message Processing, just can not influence the normal operation of system because of the difference of AM/BAM software version.
