Embodiment
The present invention proposes a kind of data capture method based on video file, and this method is applied in the supervisory control system, comprises watch-dog (as encoder etc.), memory device (as IP SAN etc.), management server and VC in this supervisory control system at least.This management server is used to realize current VM (Video Management, video management) server and DM (Data Management, data management) function of server, demand according to actual networking, can also directly dispose VM server and DM server, with Fig. 1 is grid of reference model schematic diagram of the present invention, directly disposes VM server and DM server in the supervisory control system.
Among the present invention, in order to realize the data capture method based on video file, can also dispose indexing apparatus in supervisory control system, this indexing apparatus can be functional module (as index module), and is integrated on the equipment of current supervisory control system; Be integrated on the DM server or be integrated on the VM server or be integrated on the memory device as function index module; For convenience of description, be that example describes with independent indexing apparatus among the present invention.
As shown in Figure 2, should may further comprise the steps based on the data capture method of video file:
It should be noted that watch-dog is that unit sends monitor data to memory device with the frame, promptly memory device is that unit receives monitor data with the frame.
The starting position (be physical address) of memory device by obtaining video file, when video file is sky, for the first frame monitor data (data 1) that receives, these data 1 are written to the starting position of video file, for after the monitor data (data 2 that receive ...), be written on the video file successively.
For example, X is the beginning physical address of video file, and data 1 are written to address X, and to upgrade next writing position be X+Y (Y is the size of data 1), when receiving the data 2 of next frame, directly data 2 is written to address X+Y, by that analogy.
Identification information, monitor data time information corresponding, the monitor data that step 203, indexing apparatus are obtained the watch-dog that sends this monitor data is written to the stored position information of memory device.
At this monitor data, indexing apparatus can obtain the identification information of the watch-dog of monitor data correspondence from monitor data.
When memory device was stored this monitor data by video file, this stored position information can be the physical location information of this monitor data in memory device.With data 1 is example, if data 1 are written to address X, this address X is the physical location of memory device, can uniquely inquire corresponding monitor data by address X.Perhaps,
This stored position information can also for: this monitor data is at the relative position information (being the positional information that monitor data is written to video file) of video file and the routing information of video file.With data 2 is example, if data 2 are written to address Y, this address Y is the relative position information of video file; In addition, for the video file of storage data 2, indexing apparatus can be known the routing information of this video file; Path by address Y and video file can uniquely inquire corresponding monitor data.
This monitor data time information corresponding is: watch-dog sends the time of this monitor data, and perhaps, memory device receives the time of this monitor data.
Consider the time-delay situation of transmission data between watch-dog and the memory device, temporal information can send the transmission time information of data for watch-dog, in this case, portability temporal information in the data, indexing apparatus are obtained the transmission time information of data by the temporal information of carrying in the data.
Concrete, memory device can extract the transmission time information in the data, and sends to indexing apparatus; This transmission time information can be absolute time (as 2011-01-0 110:00:00), and indexing apparatus determines that this absolute time is a transmission time information; This transmission time information can be relative time (being the side-play amount of relative previous frame data), as time of previous frame be 2011-01-01 10:00:00, relative time is 1s, then indexing apparatus determines that transmission time information is 2011-01-01 10:00:01.
Consider the transmission strategy of watch-dog, can not carry temporal information in the data, in this case, temporal information can receive the receiving time information of data for memory device; The receiving time information that memory device directly will receive data sends to indexing apparatus.
Be provided with contingency table in the database of DM, this contingency table is used to write down the temporal information of monitor data, the stored position information that monitor data is written to memory device, the identification information that sends the watch-dog of this monitor data; With the stored position information is that monitor data is an example at the relative position information of video file and the routing information of video file, then when satisfying write-in policy, indexing apparatus can be written to the information (being time information, relative position information, routing information, identification information) of monitor data correspondence in the contingency table of database of this DM.
Mode one: if current monitor data time information corresponding and the interval that write in contingency table last time between the temporal information of monitor data are not less than the scheduled time (as 1s), then indexing apparatus determines to satisfy write-in policy.
For example, write the information of data 1 last time in contingency table, the temporal information of data 1 is time A, and the temporal information that then write monitor data last time in contingency table is time A; When receiving data 2, the interval of the temporal information of data 2 and time A is less than 1s, then the information of data 2 is not written to contingency table; By that analogy, when receiving data 10, the temporal information of data 10 (time B) is not less than 1s with the interval of time A, then the information with data 10 is written to contingency table, at this moment, the temporal information that write monitor data last time in contingency table is time B, by that analogy.
Mode two: if the data bulk that writes in contingency table current monitor data and last time between the monitor data is not less than predetermined value (as 100 frames), then indexing apparatus determines to satisfy write-in policy.
For example, write the information of data 1 last time in contingency table, data 1 are the 1st frame data, and then writing monitor data last time in contingency table is the 1st frame data; When receiving data 2, data 2 are the 2nd frame data, and the data bulk between the 2nd frame data and the 1st frame data is less than 100 frames, and the information with data 2 is not written to contingency table; By that analogy, when receiving data 101, data 101 are the 101st frame data, and the data bulk between the 101st frame data and the 1st frame data is not less than 100 frames, the information of data 101 is written to contingency table, write monitor data last time this moment in contingency table be the 101st frame data, by that analogy.
Need to prove,, need the information of these data is written in the contingency table,, then adopt above-mentioned strategy to judge whether the information of current data is written in the contingency table for follow-up data for first frame data that are stored in video file.
As shown in table 1, the signal situation of the contingency table when the scheduled time is 1s in the mode one, and stored position information is that monitor data is at the relative position information of video file and the routing information of video file.
Table 1
By the situation of table 1 record, when needs are checked appointment watch-dog, the video recording data of fixed time, then can retrieve the position that monitor data write in the 1s, thereby can obtain the video recording data of fixed time accurately.
The contingency table that writes down in the database based on above-mentioned DM when VC need check appointment watch-dog, the monitor data of fixed time, can also may further comprise the steps:
For example, identification information in the request is video camera 1, when temporal information is 2011-01-01 10:00:01, DM is by the contingency table shown in the question blank 1 (stored position information is relative position information and routing information), the routing information that can know video file be HD1 Camera01.video, relative position information is X+1000, afterwards, DM can by VM with HD1 Camera01.video and X+1000 send to VC.
For example, VC by routing information HD1 Camera01.video find video file from memory device, and from video file, obtain data to be checked, and watch video recording by positional information X+1000.
Among the present invention, when the path of video file changed (position of having moved video file as the user) or need the deletion video file, then indexing apparatus upgraded corresponding record in the database of DM.
Concrete, when the path of video file changed, indexing apparatus obtained the path of the video file after the variation, and replaced the routing information of the video file that writes down in the contingency table by the path of the video file after changing.For example, when the position of video file A became FilePathB, then indexing apparatus upgraded the record of video file A correspondence in the contingency table, is FilePathB with the current path information updating.
When needs deletion video file, the record of video file correspondence in the indexing apparatus deletion contingency table.For example, when needs were deleted the video file A of appointment, then the routing information with video file A was the condition query contingency table, with the relative recording of deletion video file A.
Based on the inventive concept same with said method, the invention allows for a kind of management server, be applied in the supervisory control system, when the memory device in the described supervisory control system receives monitor data from watch-dog, described memory device is stored described monitor data by video file, as shown in Figure 3, this management server comprises:
