Embodiment Construction

[0026] The embodiments of the present invention will be further described below in conjunction with the drawings and embodiments.

[0027] image 3 It shows the principle of asynchronously loading the pulse train signal into the synchronous communication channel of the present invention. See image 3 , the process of asynchronously loading a synchronous communication channel is as follows.

[0028] (1) The slave and the master side form a pulse frame in a framed manner with their own periodic pulses within a pulse cycle, and put them into the transmission sequence of the E1 uplink and downlink synchronous channels to form a pulse transmission frame;

[0029] (2) The other party in the receiving channel sequence can receive the corresponding pulse frame, and determine the position of the pulse frame according to the de-framing of the pulse frame;

[0030] (3) Measure the time interval of the corresponding pulses of the sending pulse frame and the receiving pulse frame relati...

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...
