Problems solved by technology

At present, the VBC communication method mostly adopts a single verification method, which only performs a single verification at the link layer or application layer, and there is no clear fault location method after the verification
As a result, it is impossible to quickly and effectively locate the type of data transmission error, resulting in abnormal data communication failures that occur from time to time, but it is difficult to locate and solve them

Abstract

The present invention provides a high-reliability HDLC communication information verification method and device applied to a flexible straight valve base control system. CRC check is performed on the received data, the data includes frame header, user data R0-R6, checksum check code R7 and CRC check code; after the CRC check is passed, checksum check is performed on the data. After the verification and verification are passed, word verification is performed on the data; after the word verification is passed, continuous judgment is performed on the data. The technical solution provided by the present invention enables the HDLC communication of the flexible direct current transmission system VBC to have extremely high stability and reliability. When the message is correct, it can ensure that the message passes the verification; when the message is wrong, it can ensure that the erroneous message is quickly and reliably screened out and reported.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to a high-reliability HDLC communication information verification method and device applied to a flexible straight valve base control system. Background technique [0002] The converter valve is responsible for the DC-AC conversion and the AC-DC conversion in the DC transmission project, and is the core equipment of the DC transmission project. When the flexible DC transmission modular multilevel (MMC) converter valve technology is applied in the field of HVDC transmission, hundreds or even thousands of sub-modules are required to be connected in series, and each sub-module must be controlled, protected and monitored individually. As the interface equipment of the control protection system and the converter valve, the valve base control system VBC undertakes the heavy responsibility of the operation control and safety protection of the entire sub-module, the e...
