Further, described frequency spectrum purpose monitoring device is a spectrum analyzer.
Further, described terminal monitoring monitoring subsystem carries out purpose monitoring for the file that sub-headend and chain service network are received, thereby obtains reception integrity degree and the packet loss of described file.
Further, also comprise:
Picture purpose monitoring subsystem, be connected with described code stream purpose monitoring subsystem, video file the described file for the treatment of satellite propelling movement receiving from described code stream purpose monitoring subsystem is resolved and storage, and then show in the mode of a speed or multiple velocity by the mode of many pictures, thereby described video file is carried out to purpose monitoring.
Further, terminal monitoring monitoring subsystem also comprises:
Passback device, is connected with described picture purpose monitoring subsystem, and the reception integrity degree of the described file that described terminal monitoring monitoring subsystem is obtained and packet loss return to described picture purpose monitoring subsystem.
Purpose monitoring system of the present invention is carried out purpose monitoring by the signal of the data to the transmission of up link Satellite, the transmission of down link Satellite and the file that terminal receives.When thereby the quality of the file receiving as user is lower, O&M personnel can quick and precisely analyze the reason that document quality is lower and come across up link, down link or terminal, so that fast and accurately to causing the fault that document quality is lower to remove, thereby ensure that the file that user receives has higher quality.
The monitoring and surveying result of frequency spectrum purpose monitoring device of the present invention can directly reflect the spectrogram of the signal of down link Satellite transmission, and whether purpose monitoring signal has interference signal to exist around and the type of interference signal, according to the type of the interference signal analyzing, the source of location interference signal fast, thus in time interference signal is removed.
Before satellite pushes, picture purpose monitoring subsystem of the present invention can be treated the mode that the video and audio index of the video file in the described file of propelling movement shows with a speed or multiple velocity by many pictures and carry out purpose monitoring, thus in source to the quality of video file in addition control.
