Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0021] The present invention comprises the following steps:

[0022] 1) During the time synchronization process of the data link networking system, the data link system adopts a comprehensive automatic synchronization technology that combines round-trip ranging time calibration and external clock synchronization to realize time synchronization between nodes of the data link system;

[0023] 2) During the operation of the data link network, an automatic switching control method is adopted for the data link mobile nodes to realize continuous communication with the data link mobile stations.

[0024] refer to figure 1 , which describes the overall process of the non-relay networking. First, each user in the data link network is initialized separately, and then the integrated ...

Abstract

The invention discloses a data link unrepeatered networking method. According to the method, each user in a data link network is initialized firstly, then time correction is performed with a comprehensive automatic synchronization technology, when all users finish the time correction work, synchronization of the users of the whole network is realized, and communication connection can be established between the users. Each mobile user in the data link network monitors own state at any moment, and triggers a handover flow instantly when finding that handover conditions are met. By means of the method, available resources of a data link system are not reduced, and a networking area of the data link system can be enlarged.

Description

technical field [0001] The present invention belongs to the general technical field of the data link system, data link network organization, networking, etc., especially relates to the wireless networking mode of the data link system network and the method of expanding coverage, and is directly applied to the design of the tactical data link system and development. Background technique [0002] A data link is an information system that transmits digital information in real time. Currently, commonly used data links include Link 4, Link11, Link 16, and Link 22. The working frequency bands mainly include HF, UHF, and Lx. The networking methods mainly include point-to-point, polling, multicast, and broadcast. Due to the characteristics of line-of-sight communication in the Lx and UHF working frequency bands, in order to expand the coverage area of ​​the networking, it can only be realized through the relay method. The networking area is proportional to the number of relay stag...
