Embodiment

[0045] combined with figure 1 , the present embodiment discloses a civil aviation surveillance source video playback analysis system, which communicates with Asterix radar signals, and includes a video display module and a playback analysis module; the video display module includes:

[0046] The message receiving unit, the message receiving unit obtains the network message data of different devices through the Asterix radar signal, and monitors the communication status of the Asterix radar signal. When it is judged that the data has not been received for a long time within the message or the network connection is abnormal, a warning prompt will be displayed , wherein, the network message data collected by the message receiving unit includes UDP messages, UDP broadcast messages, UDP multicast messages, and TCP client or server messages, and the message receiving unit has the function of multi-channel reception , able to receive data from multiple different IP sources of Raytheo...

Abstract

The invention discloses a civil aviation surveillance source video playback analysis system, which comprises a video display module and a playback analysis module, and is characterized in that the video display module comprises a message receiving unit, a file storage unit, a format decoding unit, a target display unit, a map library file unit, a map selection unit and a target screening and statistical display unit; the playback analysis module comprises a video playback unit, an all-target display unit, a mirror image false target display unit and an all-drop-point target display unit, and the system can collect all paths of signals and collect signal data so as to facilitate later playback analysis; meanwhile, the receiving unit also has a real-time analysis function and can judge whether the radar source signal has data or not; and the playback analysis module can be used for playing back and analyzing the monitoring sources, so that a technical support department can conveniently know the monitoring strength and weakness of each monitoring source.

Description

technical field [0001] The invention relates to the field of civil aviation surveillance systems, in particular to a civil aviation surveillance source video playback analysis system. Background technique [0002] In 2015, radars in Shanghai encountered radio interference incidents. In order to facilitate the daily work of statistics on flight route drop points, the staff of the Technical Support Center designed a set of analysis and processing tools for daily video files based on radar principles and computer knowledge. Through this The tool can easily find the location of the radar drop point. First, it can reduce the number of on-duty personnel to visually analyze the drop point and increase work efficiency. Second, it can facilitate statistics and help the radio agency quickly find out the source of interference. [0003] However, in later work, I found that the playback speed and efficiency of the recording and playback tools in daily work are slow, low in efficiency, a...
