Abstract

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. According to the checking and self-checking method, by using flexible extension characteristics of the TLV in the transmission process, the Unconfirmed-PDU definition in the IEC61850 isextended, checking for the InformationReport message data is improved, and the checking codes for the InformationReport message data are added, so that when a data receiver receives message data, themessage can be checked, and the correctness detectability of data message transmission is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a message verification method during data transmission. Background technique

[0002] The IEC61850 standard is the only international standard for substation automation systems based on a general network communication platform, and is formulated by three working groups 10, 11, and 12 (WG10 / 11 / 12) of the 57th Technical Committee of the International Electrotechnical Commission (IEC TC57). The application of the IEC61850 standard makes the implementation of smart substation projects standardized, unified and transparent. No matter which system integrator builds the smart substation project, you can understand the structure and layout of the entire substation through the SCD (system configuration) file. For smart The development of modernized substations plays an irreplaceable role.
