Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Such as figure 1 The provided monitoring method for radio voice services on water is characterized in that it is completed by using communication technologies including multi-channel voice splicing synchronous transmission technology, multi-channel spectrum data splicing technology, and multi-channel control technology based on the water voice communication database. Signal capture and front-end signal processing, wide and narrowband spectrum data acqui...

Abstract

The invention provides a water radio voice service monitoring method. The method adopts a multichannel voice splicing synchronous transmission technology, a multichannel spectral data splicing synchronous transmission technology, a multichannel controllable technology based on a water voice communication database and other communication technologies to finish signal acquisition and front end signal processing, wideband and narrowband spectral data acquisition and multichannel audio demodulation, data transmission, data splicing, spectral display, voice playing and other processes. Through the above way, the water radio voice service monitoring method provided by the invention integrates A / D sampling, PCI data transmission, database comparison and language monitoring technologies, and solves the problems that the number of controllable channels and monitorable sound channels is few, the investigation process is tedious and the investigation effect is bad when conventional equipment performs water radio language service monitoring.

Description

technical field [0001] The invention relates to the technical field of radio monitoring, in particular to a method for monitoring radio voice services on water. Background technique [0002] my country is on the verge of the Yellow Sea, the East China Sea, and the South China Sea. It not only has the Bohai Sea, but also has a long coast and more than 6,500 islands. At home and abroad, the development of water services is vigorously advocated. The number of ships has increased dramatically, and the water radio voice service has also grown rapidly. At the same time, the increase in the number of ships has also led to an increase in the number of ships in danger. [0003] my country's short-distance distress alarm and communication frequency band is 156MHz~174MHz, mainly including distress and safety call frequency (156.525MHz), distress safety communication frequency (156.800MHz), navigation safety ship-to-ship communication frequency (156.650MHz), search and rescue operations...
