According to the correct structure of bag, following analysis has been carried out to both error conditions：In correct packet structure, data packet head it
It is preceding there is no redundant character, there is no redundant character after packet tail yet, and in data packet head, valid data and packet tail
Each character should be the significant character (such as ASCII character) pre-set；If receive packet in, data packet head it
Before redundant character be present, either exist in redundant character or data packet head, valid data and packet tail after packet tail
Character be not significant character, then should all handle, that is, be deleted according to error code.
