Abstract

The invention discloses a time synchronization detection method based on acquisition terminal B code time synchronization, which mainly comprises a time synchronization state on-line monitoring protocol configuration checking method based on B code time synchronization, and the method comprises the following steps: testing a protocol supported by a detected acquisition terminal, and recording protocol configuration and functions supported by detected equipment; the invention discloses a communication protocol detection method of a time synchronization online monitoring function based on B code time synchronization. The method comprises the following steps: detecting a time synchronization signal state, a time synchronization service state and a time jump detection state; a detection method of a time synchronization state detection function based on B code time synchronization comprises the following steps: simulating scenes of different time synchronization deviations of detected equipment, and detecting whether the time synchronization state detection function of an acquisition terminal meets requirements or not; the invention relates to a method for detecting an equipment state self-checking function based on B code time synchronization, which respectively simulates each scene of a time synchronization interface self-checking function, a time synchronization service state self-checking function and a time jump detection state self-checking function, and detects whether the equipment state self-checking function is correct or not.

Description

technical field [0001] The invention relates to the technical field related to power system communication technology, in particular to a time synchronization detection method based on B code time synchronization of a collection terminal. Background technique [0002] In recent years, the B code time synchronization system is gradually being widely used in the industrial field, especially in the power system and power industry. The time information can be accurately provided through the clock synchronization of the substation, and it can be used as a fault indicator and relay protection device in the power system. , RTU monitoring system and other automation equipment provide a unified time reference and time basis, which is convenient for accurate analysis of the cause and process of the accident. Clock synchronization has become a key link in the comprehensive automation of the power grid. However, the existing B code time synchronization scheme lacks a method for detecting...
