Dynamic compensation pulse circuit

Abstract

The invention discloses a dynamic compensation pulse circuit which comprises a signal generation module for generating a primary second pulse signal, a standard signal module for receiving a standardsecond pulse signal and capturing a rising edge time point of the standard second pulse signal; a processor for generating an updating storage value according to the rising edge time point of the standard second pulse signal; a signal adjusting module which is connected with the signal generating module and the processor and is used for receiving the updating storage value; wherein the signal adjusting module is started by the primary second pulse signal, and transmits the updating storage value to the signal generation module; and the signal generation module generates an update second pulsesignal according to the updating storage value. The method has the advantages and beneficial effects that the influence of channel transmission delay on time synchronization clock precision is eliminated, and the clock synchronization of the dynamic compensation pulse circuit and the standard time source is realized. The clock synchronization between the standard time source and the synchronized device is guaranteed, the structure is simple, and the cost is low.

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.
