Wherein, warning time information preservation scheme is a link in the intelligent video monitoring system overall plan, is used for the search of alert event afterwards and recalls.The data of report to the police preserving are complete more, and the device memory that needs when then preserving is big more, and the data volume that the supervisor need browse when recalling is also big more, and this means that also the invalid data information that comprises in the warning message is many more; The data that warning is preserved are very few, though memory device pressure diminishes, might not preserve down effective information, can't supply to search for afterwards and analyze use.
Summary of the invention
Technical matters to be solved by this invention provides a kind of alarm event information store method based on the graphical analysis alerting signal, and it has guaranteed the completeness of alarm event information, also guarantees the validity of warning message simultaneously.
The present invention solves above-mentioned technical matters through following technical proposals: a kind of alarm event information store method based on the graphical analysis alerting signal is characterized in that it may further comprise the steps:
Step 1, when video analysis, the video/audio in buffering monitored picture the first five second is preserved the video recording alert files that first three second takes place of reporting to the police and is used when supplying to report to the police;
Step 2, when alert event takes place, the image information constantly of directly grasp reporting to the police saves as the JPG picture, and is uploaded in the ftp server;
Step 3, when alert event takes place, the intercepting video in first three of reporting to the police continues the video recording five seconds in second from the video analysis buffer memory, preserves video file and also is uploaded in the ftp server.
Preferably, preserve video file in the said step 3 simultaneously, related warning video file, warning picture and other warning messages, and upload in this warning message to the ftp server and preserve.
Preferably; When intercepting video video in first three, be timeorigin at first in the said step 3 in second, search for first video hardwood forward with first three second of reporting to the police; If first video hardwood exists, be that initial hardwood is preserved all the other hardwood data successively in proper order with this first video hardwood; If do not search first video hardwood forward, be timeorigin then with first three second of reporting to the police, search for first video hardwood backward, if first video hardwood exists, be that initial hardwood is preserved all the other hardwood data successively in proper order with this first video hardwood; As do not search the information of first video hardwood in five seconds in the data in buffering, then preserve the video file failure.
Positive progressive effect of the present invention is: the present invention has preserved and has supplied to watch complete alarm content use as video file eight seconds that effective information was the highest when alert event took place afterwards; Preserve the image constantly of reporting to the police, supplied the simple queries warning message to use; Preserved the warning retrieving information, the search that supplies to report to the police is used.
Description of drawings
Fig. 1 is the process flow diagram that the present invention is based on the alarm event information store method of graphical analysis alerting signal.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
As shown in Figure 1, the alarm event information store method that the present invention is based on the graphical analysis alerting signal may further comprise the steps:
S1, when video analysis, the video/audio in buffering monitored picture the first five second is preserved the video recording alert files that first three second takes place of reporting to the police and is used when supplying to report to the police.
S2, when alert event takes place, the image information constantly of directly grasp reporting to the police saves as the JPG picture, and is uploaded in the ftp server.
S3, when alert event takes place, the intercepting video in first three of reporting to the police continues the video recording five seconds in second from the video analysis buffer memory, preserves video file and also is uploaded in the ftp server.When intercepting video video in first three in second, be timeorigin at first with first three second of reporting to the police, search for first video hardwood forward, if first video hardwood exists, with this first video hardwood be initial hardwood successively order preserve all the other hardwood data.If do not search first video hardwood forward, be timeorigin then with first three second of reporting to the police, search for first video hardwood backward, if first video hardwood exists, be that initial hardwood is preserved all the other hardwood data successively in proper order with this first video hardwood.As do not search the information of first video hardwood in five seconds in the data in buffering, then preserve the video file failure.In actual use, the continuous phenomenon of not having first video hardwood in two seconds never takes place.Preserve video file simultaneously, related warning video file, warning picture and other warning messages, and upload in this warning message to the ftp server and preserve.
