Description
Technical field
The present invention relates to intelligent acoustics to monitor field, and in particular to a kind of emergency event monitoring system of acousto-optic linkage and
Method.
Background technique
Large-scale public place or important communal facility, such as: Metro hub, large-scale stadium, walking shopping street,
Airport station etc. is that the place of crowd's high concentration and public safety critical incident most easily occur, prevention and control and emergency disposal
It is most difficult, most it is also easy to produce the place of extensive casualties.As Chinese society, economic development enter critical stage, sponsor and
The various large-scale activities undertaken are more and more, and the safety problem faced and challenge are also more severe.
Currently, municipal public safety monitoring mostly uses video system, the anomalous event monitoring calculation amount based on video image
Greatly, the real-time processing of Yao Shixian massive video data, calculating is with high costs, therefore mostly uses manually check mode at present, thus
It not can guarantee real-time and be easy false dismissal.Acoustic monitoring method has the characteristics that round-the-clock, real-time, low-power consumption, is military, peace
A kind of effective monitoring and warning means in anti-and anti-terrorism application.
Summary of the invention
The main object of the present invention is overcome at present using drawbacks described above existing for video system detection emergency event, is examined
Consider: crowded place, such as airport, subway, railway station, bus station, hospital hall, gymnasium, music hall place sound

The camera, the orientation estimated information that processing module issues for receiving data turn to corresponding region and are regarded
Frequency is checked；
The data processing module, the acoustical signal for sending to data collection host carry out detection identification, when detecting
When emergency event, estimate based on database identification events type and to emergency event orientation, is then sent to monitoring personnel
Alarm sends orientation estimated information to camera and checks emergency event by the video information of acquisition；And it is based on event type,
Emergency event is guided and is intervened；
The alarm loudspeaker intervenes emergency event for issuing warning information.
Based on above system, the present invention also provides a kind of emergency event monitoring method of acousto-optic linkage, the method packets
It includes:
Acoustical signal in step 1) the microphone array acquisition monitoring area, acoustical signal are transmitted through data collection host
To data processing module；
Step 2) the data processing module detects acoustical signal, when signal energy is more than given threshold, the number
Alarm is sent to monitoring personnel according to processing module, while orientation is occurred based on microphone array column data estimation event, and issue
Turn the instruction of camera to the orientation zone, carries out video acquisition, be transferred to step 3)；Otherwise, it is transferred to step 1), is continued
Monitoring；
Step 3) identifies the acoustical signal of acquisition, if certain malignant event class in the event type and database of identification
Type is consistent, while checking emergency event according to the video content of camera, then the event type according to identification, starting pair
4) the emergency preplan processing answered, enters step；If certain malignant event Type-Inconsistencies in the event type and database of identification
When, emergency event is checked according to the video content of camera, then indicates that related personnel enters emergency event scene and shows
Field processing, is transferred to step 4)；
Step 4) monitoring personnel calls alarm loudspeaker to be alerted according to the live event developing state of video monitoring,
Emergency event is guided and is intervened.
As a kind of improvement of the above method, in the step 3), if certain in the event type and database of identification is pernicious
When event type is inconsistent, the corresponding acoustical signal of the event is imported into database, and handmarking's data type.
Present invention has an advantage that
1, system of the invention can be realized shot in round-the-clock real-time automatic monitoring identification social environment, explosive sound,
The emergency events such as personnel's shriek, traffic accident；It supports networking audible alarm, intervenes control impact development in time；
2, system of the invention supports the real-time positioning of the malignant events such as shot, explosive sound, acoustic monitoring positioning result connection
Dynamic video system, quasi real time shows event video image；
3, monitoring system through the invention can quick and precisely identify the acoustic target characteristic of different event, realize prominent
The automatic quick examination and positioning of hair event can provide Information base for the quick reply of emergency event；Monitoring system is being examined
Directional information can be provided while surveying identification events, so that matched video monitoring system is called to be checked automatically, event
Broadcast system is equally supported to intervene and guide event after confirmation, to realize to crowded place emergency event
The audio-video of round-the-clock real time monitoring and quick response, event whole process is automatically stored, convenient for investigating and collecting evidence；
4, system and method for the invention can be realized at the real time monitoring and guidance of crowded place emergency event
Reason, provides effective means for urban safety management and anti-terrorism early warning.
