Checking and self-checking method for message transmission of IEC1850 report data

The invention discloses a checking and self-checking method for message transmission of IEC1850 report data. The method is characterized in that the method comprises the following steps that A, an MMSserver-side conducts extension on a UnconfirmedPDU structure of an MMS, checking for an InformationReport message structure is improved, checking codes for the InformationReport message structure areadded, and a report message with the checking codes is generated; B, the report message with the checking codes is transmitted on the TCP/IP; C, after an MMS client receives the report message with the checking codes, an Unconfirmed-PDU is parsed, and an eight-bit checking sum code and an InformationReport message TLV with the checking codes are obtained; D, the checking sum code which is obtained in the third step is compared with a VALUE value, and if the checking sum code which is obtained in the third step is equal to the VALUE value, data transmission is right, and InformationReport datais credible.
