Maritime radio voice service monitoring method

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...

AI Technical Summary

Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to provide a water radio voice service monitoring method, which solves the problems of the controllable and guardable channels and the small number of monitorable channels, cumbersome investigation process and poor investigation effect when conventional equipment is used for water radio voice service monitoring.
