Example Embodiment

[0022] The shortwave ad hoc network link system of the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification:

[0023] It includes shortwave radio, modem, single-chip microcomputer, RAM memory, GPS module, GPS antenna. It is characterized by the combination of marine shortwave radio and shore station at sea to form a large network, when shortwave radio and shore station exceed communication During the distance, other shortwave radio stations in the middle position forward the voice call mechanism to expand the communication distance of the shore station, so that the shore station can relay voice calls with marine shortwave stations around the world, and realize the ad hoc network link of shortwave communication.

[0024] The single-chip microcomputer reads the clock signal of the GPS module, and calculates the time to transmit the digital beacon 1 according to the ID of the short-wave station. The single-chip m...

Abstract

A short wave ad-hoc network link system comprises a short wave radio station, a modem, a single-chip microcomputer, an RAM and a GPS antenna. The short wave ad-hoc network link system is characterized in that marine short wave radio stations and a base station are combined to form a large network, and when the distance between a short wave radio station and the base station is beyond the communication distance, a mechanism of performing forwarding of voice calls through other short wave stations at intermediate positions is established to enlarge the communication distance of the base station, making the base station realize relay voice calls with marine short wave radio stations around the world and realizing ad-hoc network links of short wave communication. Compared with link systems in the prior art, the short wave ad-hoc network link system is simple to operate, stable in running, strong in practicality, and can overcome instability of communication channels and influences on communication distances by noisy electromagnetic environments.

Description

1. Technical field: [0001] The invention provides a short-wave ad hoc network link system, which belongs to the electronic communication system in marine communication. 2. Background technology: [0002] At present, with frequent offshore operations, emergency communication will be an indispensable link, which supports the smoothness and safety of offshore operations. Once a war or disaster occurs, various communication networks may be damaged, and satellites may also be attacked. Regardless of the communication method, its invulnerability and autonomous communication capabilities are incomparable with shortwave. However, the short-wave radio station is also affected by the unstable ionosphere and weather, there are many communication blind spots, and the communication distance is also restricted by the noisy electromagnetic environment. When the ocean communication cannot be reached, it can only rely on other communication methods , the present invention is to solve this ...
