Embodiment

[0036] combine figure 1 , figure 2 and image 3 , a kind of multi-user distributed emergency communication synchronous method based on shortwave communication network of the present invention, comprises the following steps:

[0037] Step 1: Configure the network. The system deploys 1 superior center and M (M is a natural number) regional centers, and N (N is a natural number) remote stations are deployed in M ​​regional centers. The superior center is interconnected with the M regional centers, and each of the M regional centers is interconnected through a reliable communication network. The regional center and the remote station configure the main link and configure the short wave as the emergency communication network at the same time. The application scenarios are as follows: figure 1 shown.

[0038] For the shortwave emergency communication network, the network structure of the present invention is as follows figure 2 As shown, a set of short-wave center controller...

Abstract

The invention discloses a multi-user distributed emergency synchronous networking method based on short-wave communication. The method first constructs an optimized short-wave network equipment configuration scheme; The channel table planning method; then, the multi-user distributed network control and transmission mechanism in the synchronous network mode is designed. The present invention not only reduces the cost of the shortwave communication network structure through multi-station antenna sharing and synchronous networking methods, but also completely solves the problem of multiple stations and antenna co-location interference; and through the timing switching of the call channel table, shortens the call link establishment cycle and improves synchronization efficiency ; Through the dynamic access of multi-receivers in the center and the dynamic scheduling of multi-receivers in the whole network, the multi-user distributed on-demand access and dynamic sharing of resources in the whole network are realized.

Description

technical field [0001] The invention belongs to the field of network data communication, and relates to a multi-user distributed emergency synchronous networking method based on short-wave communication. Background technique [0002] The short-wave communication network mainly uses ionospheric reflection to realize limited data or voice low-speed transmission. It is a typical narrow-band low-speed communication method. It has unique advantages such as low construction cost, flexible deployment, and strong invulnerability. , Long-distance communication, especially suitable for data transmission networks with limited communication infrastructure and small transmission traffic. [0003] With the expansion of the coverage area of ​​broadband communication networks such as terrestrial optical fiber, satellite and microwave, the use of short-wave communication networks as the main communication network is decreasing. However, for important business systems, a set of The emergency...
