Method and apparatus for monitoring operation status of broadcast television satellite transmission system

Abstract

This device consists of the couple receiver, the down-going receiver, the channel monitor, the freq spectrum instrument, the transferring flow comparer, the transferring flow recorder, the gateway, the net switcher, the monitor server and the monitor terminal. This method includes: (1) using computer technique to collect real time the channel error ratio (CER) and the freq spectrum signal (FSS) of up-going / down-going program of the broadcasting TV satellite; (2) comparing the code flow and analyzing FSS and CER to judge the vicious interfere and to raise automatically the up-going power to oppugn fast and accurately the illegal interfere. This invention possesses functions, such as: monitor, supervision / control, failure auto diagnosis and intelligent management, etc.; and features of the data real time record, the log searching and the failure note sending, etc.

Description

technical field

[0001] The invention relates to a monitoring terminal, in particular to the working status of broadcast and television satellite transmission system equipment. Background technique

[0002] The satellite broadcasting system includes video and audio switchers, encoders, multiplexers, modulators, upconverters, high-power amplifiers and waveguide switchers, etc., some of which have their own independent control workstations, and some have no intelligent control and monitoring equipment to achieve A unified equipment monitoring, alarm and management platform can greatly reduce the labor intensity of personnel, especially combat illegal attacks and interference, and ensure safe and reliable broadcasting.

[0003] At present, manual methods are used to observe the spectrum analyzer and TV decoding images to monitor the attack situation, which is labor-intensive. In many cases, the spectrum and image signals cannot accurately and quickly reflect the interference of ...
