A Dynamic Compensation Pulse Circuit

Abstract

The invention discloses a dynamic compensating pulse circuit, comprising: a signal generating module for generating a preliminary second pulse signal; a standard signal module for receiving the standard second pulse signal and capturing the rising edge time point of the standard second pulse signal; processing The device is used to make an update storage value according to the rising edge of the standard second pulse signal; the signal adjustment module is connected to the signal generation module and the processor respectively, and is used to receive the update storage value; the signal adjustment module is started by the preliminary second pulse signal, The updated stored value is transmitted to the signal generation module; the signal generated module generates an updated second pulse signal according to the updated stored value. The advantages and beneficial effects of the present invention are: the influence of the channel transfer delay on the accuracy of the time synchronization clock is eliminated, the clock synchronization between the dynamic compensation pulse circuit and the standard time source is realized, and the clock between the standard time source and the synchronized device is guaranteed Synchronization, simple structure and low cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a dynamic compensation pulse circuit. Background technique [0002] Time-synchronized clock technology is applied to all links in the field of industrial control and is the main coordination basis for the collaborative work of automation systems. For example, the satellite-synchronized clock of the power system is an important device dedicated to realizing time-synchronized clocks for the secondary control equipment of the power system. The satellite synchronous clock receives the standard time broadcast by the satellite, converts it into a standard time synchronization signal, and realizes the time synchronization clock of the equipment in the two places through a dedicated communication medium in different locations such as the master station and the factory station. Among them, it is necessary to use a standard communication channel, which is usually a punctual pulse or a standard ti...

However, in the actual process, when the clock device transmits the pulse signal to the equipment, it may pass through different communication media or routes, such as the E1 channel of the SDH communication network, thus causing the clocks between the standard time source and the synchronized equipment to be out of sync.
