Method for asynchronously loading and accurately positioning impulse signal in synchronious channel

Abstract

The invention discloses a method for asynchronously loading pulse signal into synchronous channel and accurate positioning, which solves the problem that pulse signal is asynchronously loaded into synchronous channel through framing method in the process that automatic time delay compensation is realized in E1 synchronous communication channel. The technical proposal includes that based on the bidirectional pulse time delay compensation principle, the method realizes automatic time delay compensation in E1 synchronous communication channel; the problem that pulse signal is asynchronously loaded into synchronous channel through framing method in the process is solved, and the problems of performing positioning in frame transmission process and improving positioning accuracy are solved. The invention is applicable to time synchronous apparatuses.

Description

technical field [0001] The invention relates to a method for loading pulse signals into a channel and positioning, in particular to a method based on the two-way pulse method time delay compensation technology, adopting an asynchronous frame loading scheme, supporting positioning measurement and phase adjustment technology, in order to realize channel The method provided by the phase automatic synchronization of the pulse generator of the time synchronization equipment at both ends. Background technique [0002] In the field of time synchronization, the two-way pulse method is commonly used to compensate time signal transmission delay. For the principle and delay compensation process of the two-way pulse method, see figure 1 , the two parties send correction pulses to each other at the same time, and calculate and compensate the signal transmission delay. The process is described as follows: the two parties agree to send correction pulses to each other at the time when the a...
