Description
Technical field
The present invention relates to areas of information technology, the specifically a kind of audio signal based on generalized information system transfers method.
Background technology
The sense of hearing is the most important approach in the human perception external world, is the most naturally most common behavior of the mankind, the mankind are recognized
Know the world activity for be irreplaceable.By the cognitive external world of various audio-visual apparatus sense organs, " listening " be it is most natural,
Most directly, it is also most important means.Sense organ function based on vision and the sense of hearing carries out mesh by sensory channel to things
Target locking, the extraction and integration of information, are formed to features, are carried out overall, accurate description and are judged, are finally completed people
The cognitive function of class.Audiovisual can provide object of cognition, most objective informations in the cognitive world, and its cognitive features is most can be according to
Bad." seeing " and " listening " of the mankind is not only natural physiological behavior, and even more social action is even more embodied in the day of " audiovisual combination "
Chang Hangwei.
In recent years, with China's expanding economy and the continuous improvement of overall national strength, constantly lifted in China's international status
While, domestic social contradications are also increasingly highlighted, and particularly global anti-terrorism situation is still abnormal severe, although various countries' high pressure is beaten
Hit, but threaten and still spreading.Therefore the anti-terrorism of China, stability maintenance situation allow of no optimist, and the threat of terrorism faced tends to be tight
It is high.Seat of government, crowded place (square, railway station, high ferro station, passenger transport central station and airport), water, electricity, gas, heat
The facility for being related to the people's livelihood is all that we want emphasis prevention and control " keypoint part ".Keypoint part three-dimensional live solid prevention and control system is with three
Tie up based on outdoor scene system, fully integrate GIS-Geographic Information System, video monitoring system, face bayonet socket, vehicle bayonet socket, electronics and enclose
Multiple systems such as column, GPS location.So that the multiple element such as police strength distribution, video image, alarm signal is intuitively in three dimension system
In shown, many problems such as system can solve intelligent discovery, quick disposal, track is searched, evidence is fixed, effectively
Improve the prevention ability of keypoint part and the disposing capacity of accident.
At present, all it is to occupy directly invoking for Audio Matrix and audio server for calling for audio, for audio
Sound pick-up on the particularly avenue of outdoor of covering position is not shown intuitively, it is impossible to reach that " audiovisual combination " is complete anti-
Features are reflected, the purpose that people can accurately perceive.In large-scale safety and protection system and smart city system, into
Fast selecting is to the audio of relevant position, it is necessary to which operating personnel are distributed to geographical and each sound pick-up in thousand sound pick-ups up to ten thousand
It is well understood by, current people not yet work out method and reach this purpose.
The content of the invention
Method is transferred it is an object of the invention to provide a kind of audio signal based on generalized information system, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of audio signal based on generalized information system transfers method, comprises the following steps that：
Step one, sound pick-up is set up in front end, and microphone signal is transmitted to audio server or Audio Matrix；
Step 2, sets up the figure layer of video covering domain in generalized information system, is picked up in audio covering domain figure layer, according to pickup
The gps coordinate of device installation site and the technical indicator of sound pick-up mark out position and the pickup scope of each sound pick-up, will be each
The covering domain of sound pick-up and the output of audio server or Audio Matrix are corresponded, and are used as correspondence audio signal in generalized information system
The foundation transferred；
Information according to audio covering domain figure layer is judged current generalized information system by step 3, when the switch is opened, device
Whether there is audio to cover and the quantity containing audio in the range of viewpoint, when only containing audio all the way, directly export；When containing many
During the audio of road, MCVF multichannel voice frequency is first subjected to audio mixing, then using after audio mixing when audio is used as output；
Whether step 4, the viewpoint for observing current generalized information system produces change, and new regard is transferred in the action of repeat step three
Point is corresponding to work as audio.
It is used as further scheme of the invention：The technical indicator of sound pick-up includes the effective pickup distance and pickup of sound pick-up
Angle.
Compared with prior art, the beneficial effects of the invention are as follows：The method that the present invention is used has suitable for large scale system
What is imitated solves under a wide range of scene to audio signal the problem of transferring, and has been obviously improved speed and prison to target detection
The operating efficiency of control system；By the linkage of the present invention and video monitoring system, it can efficiently solve because video covering domain is remote
The unsharp problem of audio ＆ video correspondence caused much larger than effective covering domain of audio, is the command scheduling of love scene
Evidence afterwards, which is fixed, provides effective technical support, is that city management or social security integrate command scheduling platform, solves
Certainly basic audio resource access-in management and application, can under battle conditions command for sound, video visualization and provide support；It is vertical in social security
Body prevention and control application system, can be achieved voice data, video data, GIS-Geographic Information System and the integrated application of three-dimensional scenic, realize mark
Standardization, synthesization and the integrated prevention and control of three-dimensional.
