Shipborne communication monitoring system

Abstract

A shipborne communication monitoring system disclosed by the present invention comprises a voice signal transmitting terminal, the voice signal transmitting terminal is connected with a marine communication base station through a wireless signal, the voice signal transmitting terminal is also electrically connected with a recording module, the recording module is electrically connected with a recording file transmission module, and the recording module is used for recording voice information of the voice signal transmitting terminal. The recording file transmission module is used for sending recorded voice information to the recording file receiving end through the marine communication base station, the server and the wired network, and the recording file receiving end and the voice signal receiving end are both in telecommunication connection with the voice tester. According to the invention, the voice of the voice signal transmitting end can be recorded and sent to the recording file receiving end, the voice quality can be detected more accurately by comparing real-time voice with voice recording, detection can be carried out through a PESQ system and manual reinspection, the detection modes are diversified, and the detection result is more accurate; and a delay calculation module for calculating communication delay is also arranged, so that the delay of a communication signal can be monitored.

Description

technical field [0001] The invention belongs to the technical field of marine communication base stations, and in particular relates to a shipborne communication monitoring system. Background technique [0002] At present, in the mobile communication operation network, there is a mobile communication call quality remote detection system for remote detection of mobile communication network signals or the output signals of mobile communication source equipment (repeaters, trunk amplifiers, BTS cells). Although these systems have the function of listening to the voice quality of the communication network, they can manually evaluate the voice quality of the communication network subjectively; but artificial listening and subjective evaluation of the voice quality ultimately depend on the subjective feelings of people, which is not only laborious and time-consuming, but also limited by various test conditions And the influence of the subjective factors of the testers, the reliabi...

Problems solved by technology

Although these systems have the function of listening to the voice quality of the communication network, they can manually evaluate the voice quality of the communication network subjectively; but artificial listening and subjective evaluation of the voice quality ultimately depend on the subjective feelings of people, which is not only laborious and time-consuming, but also limited by various test conditions And the influence of subjective factors of the testers, so that the reliability of the measurement results is affected to a certain extent

Especially if you want to manually listen to the voice quality of a large number of detection points and make a unified evaluation in a short period of time, this is impossible

Therefore, people are eager to have a voice quality MOS (Mean Opinion Score average evaluation method) evaluation technology based on PESQ (Perceptual evaluation of speech quality ITU-T P.862) applied to the remote detection system of mobile communication network, so as to be objective and efficient The voice quality of the output signal of the mobile communication network or source equipment (repeater or trunk amplifier) ​​can be evaluated accurately; however, the existing voice quality detection system is not effective in monitoring shipborne communication, and the detection method is relatively simple, resulting in poor detection results. precise
