Description
Technical field
The present invention relates to technical field of video monitoring, relate in particular to a kind of video monitoring system and video storage information recording method thereof.
Background technology
Along with the application of high definition in video monitoring system, to the reliability of monitor video storage, performance etc., require more and more higher.And front end IP encoder device is to the iSCSI(Internet of the Media Stream end to end Small Computer System Interface of IPSAN memory device, the SCSI host-host protocol based on internet) directly the technology of depositing is exactly a kind of good video storage scheme.On the basis of IP network, in IP encoding device, integrated iSCSI module, makes IP encoding device end to end video data to be write to IPSAN(IP Storage Area Network based on iSCSI agreement) in memory device.When the video of control point need to carry out centralized stores, front end IP encoder device is set up iSCSI with IPSAN memory device and is connected, the storage resources of IPSAN memory device is mounted to this locality by iSCSI agreement, then store video stream is carried out to iSCSI protocol encapsulation, directly adopt the mode of data block that media stream data is write in IPSAN memory device.On storage mode, the data management mode that Media Stream is directly deposited has been abandoned media server, in this way, the performance bottleneck problem of effectively having evaded the Streaming Media unloading server of initiation " dumbbell effect ", possesses good extensibility simultaneously, no matter monitoring scale has much, and whole system can not exist performance bottleneck.
And directly deposit in technology at Media Stream iSCSI, how video management server obtains the video storage information of video camera on IPSAN memory device, becomes a key issue.Because front end IP encoder is by the iSCSI agreement IPSAN memory device that writes direct, the video storage information of video camera not on video management server like this.And client is generally to initiate video frequency searching to video management server, if in retrieval, video management server is initiated the video frequency searching of this video camera fixed time section again to IPSAN memory device, will cause retrieval time long, and the search function that affects user is experienced.
The video storage acquisition of information of directly depositing for front end IP encoder device iSCSI at present, generally by data management server (Data Management, DM) video routing inspection of regular (such as every 15 minutes) execution video camera storage resources on IPSAN memory device, by locating the index data of corresponding time, collect the video storage information of video camera, and will patrol and examine result and write in the video routing inspection result table of database of video management server (Vidio Management, VM).
In the video routing inspection process of DM server, for avoiding excessive to the performance hit of IPSAN memory device, generally using some minutes (such as 5 minutes) as the minimum time particle of a video routing inspection, and by bitmap, identify corresponding time particle and whether have video.As long as this time particle has one second video, be designated 1, otherwise be 0.
When client retrieves video, first inquire about the video routing inspection result table of VM database, by checking the data bitmap of section retrieval time, judge retrieval time, whether section existed video.If the time period that exist DM server not yet to patrol and examine in section retrieval time, DM server is directly retrieved the video on IPSAN memory device, and by IPSAN memory device patrol and examine result, with database in video frequency searching result splice, splicing result is returned to client.
The scheme of the video for DM server regular visit front end IP encoder stores on IPSAN memory device, mainly there are the following problems:
In video routing inspection process, need to be according to input time, read on IPSAN memory device the index data of corresponding time period in IP encoder stores resource.For IPSAN memory device, owing to also carrying out directly depositing and write of multitude of video data simultaneously, patrol and examine the random read operation that reading out data is equivalent to disk to carry out pocket.The mechanical hard disk using for memory device, the handling property of random IO is well below order IO performance.So, whenever patrolling and examining while occurring, the IO performance of memory device will seriously reduce, and can cause the new video of IP encoder to deposit in and be a greater impact, and the situation that data are lost in storage even occurs.
Just because the performance impact of patrolling and examining for memory device is serious, therefore substantially cannot accomplish to patrol and examine the video storage information of each second of each IP encoder on IPSAN memory device.The minimum time particle that causes like this patrolling and examining the video storage information of obtaining is thicker, such as the time particle of take 5 minutes is example, as long as this has 1 second video for 5 minutes, video routing inspection result is just thought whole 5 minutes video, causes the video frequency searching result cannot correct response video actual storage situation.
Because the mechanism of patrolling and examining is the mechanism of taking turn periodically afterwards, if the cycle too short (such as the cycle is 1 minute) will produce considerable influence to the performance of DM server, IPSAN memory device etc.; If excessive cycle (such as the cycle is 30 minutes), by causing the lag time of acquisition of information long, impact second level video frequency searching an effect;
In database, be to record each time particle of IP encoder in bitmap mode, when video frequency searching, also need data bitmap to be converted to time data form like this, affect recall precision.
Summary of the invention

Embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further details, following examples do not form limitation of the invention.
The video monitoring system of take is as shown in Figure 1 example, and common video monitoring system comprises headend equipment, IPSAN memory device, data management server (DM server), video management server (VM server), also comprises client, and is used for the video wall that video shows.The present invention is based on Media Stream iSCSI and directly deposit technology, its headend equipment is generally web camera, or adopt analog video camera by IP encoder access IP network, an IP encoder can connect a plurality of analog video cameras, the present embodiment unification is commonly referred to as headend equipment by them, corresponding to a headend equipment, may be connected with multiple cameras, every video camera has the video camera sign (video camera ID) of oneself.
After headend equipment starts storage plan, by iSCSI agreement, video data is write to IPSAN memory device, and according to the response of IPSAN memory device, record the video storage information of each second video.Video storage information comprises video camera ID, video slicing number, video slicing time started and video slicing end time.If a corresponding multiple cameras of headend equipment, take every video camera as information unit, periodically the video storage Information encapsulation of all video cameras of this headend equipment is sent to DM server together; Meanwhile, the video storage information of every video camera can comprise a plurality of video slicings.
Video storage information recording method in a kind of video monitoring system of the present embodiment, as shown in Figure 2, comprises step:
Headend equipment disposes and receives the DM server parameter of its video storage information and T cycle time that reports video storage information.DM server parameter comprises IP address, the port of DM server.Headend equipment is before starting video storage plan, first on headend equipment, configure IP address, the port (can select the unappropriated non-well-known port of other services of arbitrary system) of the DM server that receives its video storage information, and T cycle time that reports video storage information.
Consider that single DM server can only process the video storage information data of some headend equipments, the principle that therefore whole video monitoring system can be based on load balancing, configures many DM servers, and different headend equipments can the different DM server of option and installment.Such as video monitoring system exists 1024 headend equipments, separate unit DM server can only carry the video storage information processing of 512 headend equipments.System can configure two DM servers like this, 1, the 513 to the 1024th headend equipment configuration DM server 2 of the 1st to the 512nd headend equipment configuration DM server.
Headend equipment reports T cycle time of video storage information, and quantity, the DM number of servers of headend equipment that can be based in video monitoring system are dynamically adjusted.For guarantee video storage acquisition of information instantaneity, take into account the performance cost of DM server and headend equipment simultaneously, advise that this Configuration Values is between 10 seconds to 30 seconds, such as 16 seconds.
Particularly, headend equipment encapsulate video storage information process is as follows:
1), headend equipment writes IPSAN memory device by video data, and according to the response record event memory of IPSAN memory device;
After headend equipment starts storage plan, by iSCSI agreement, video data is write to IPSAN memory device, and according to the response of IPSAN memory device, according to recording one-period each second video storage information corresponding to store video in the time cycle time of cycle timer setting.
2), headend equipment is video storage information notice message by video storage Information encapsulation corresponding to the store video in this cycle time according to the event memory of record and mails to data management server after arriving predetermined period.
At periodical timer, arrive after date, it is gap periods time T, the cycle time (such as 16 seconds) being configured as arrived afterwards, it is information unit that headend equipment be take the video camera that each headend equipment was comprised, and is the XML data format of corresponding several video slicings of each video camera by video storage Information encapsulation.
The video storage information format of a typical XML encapsulation format below:
The video storage information that comprises at least one video camera in visible the present embodiment XML data format, this video storage information comprises corresponding video camera ID, the video slicing number of store video in phase this week time T, and the video slicing time started of each video slicing and video slicing end time.
By above-mentioned XML data encapsulation, be the video storage information notice message of Transmission Control Protocol carrying, send to IP address, the port of configured DM server.Then start next cycle timing, according to cycle time, T periodically mails to DM server by video storage information notice message.
It should be noted that, if the network between headend equipment and DM server disconnects, headend equipment will treat that synchronous video storage information first writes in local XML file, and according to same period (such as 16 seconds), the video end time of upgrading this video camera in local XML file.Once network recovery, headend equipment is the data reading in local XML file, and immediately by data notification to DM server;
If certain video camera of headend equipment, within this cycle time, exists the video storage failure scenarios of part-time section, according to the successful time slicing of final storage, in XML, fill a plurality of video slicings (slice) information.
Such as: 1 this cycle memory time of video camera is from 2013-08-2215:03:16, to 2013-08-2215:03:32, finish, but 2013-08-2215:03:23 does not store successfully to video between 2013-08-2215:03:29,, in above-mentioned XML structure, will comprise two following slice:
Time started, the end time of slice1 is " 2013-08-2215:03:16 ", " 2013-08-2215:03:22 ";
Time started, the end time of slice2 is " 2013-08-2215:03:30 ", " 2013-08-2215:03:32 ".
In VM server database, recording the video storage information table record that each video camera is corresponding, every video storage information table record comprises: table record ID, video camera ID, video slicing time started and video slicing end time.The details that are each video slicing are recorded in video management server database, for the continuous video slicing of each video camera, and a corresponding table record, discontinuous video slicing, corresponding different table records.DM management server is loaded into local preservation for use by the up-to-date video storage information table record of each video camera in video management server when starting.
Particularly, as shown in Figure 3, upgrade the video storage information table record in video management server database, DM carries out following steps:
Whether the video slicing end time that video storage information table corresponding to this video camera that preserve step 302, the video slicing time started that judges current video burst and this locality records is continuous, if enter continuously next step, otherwise enters step 307.
The video slicing of the video storage information table record of step 303, local this video camera preserved of renewal ends up being the video slicing end time of current video burst, and the video slicing of cumulative current video camera renewal count value.
Local video storage information table record corresponding to each video camera of preserving, all corresponding one is upgraded count value, this upgrades count value is the statistics of this table record update times, after reaching certain quantity, carries out the renewal of the video storage information in video management server database.Can avoid upgrading frequently like this performance of the system of impact, after the video storage table record in each more new database, this be upgraded to count value clear 0.
The video slicing end time of the video storage information table record of step 307, this video camera of preserving with this locality, upgrade the video slicing end time of the up-to-date video information table record that in video management server database, this video camera is corresponding, the video slicing of current video camera is upgraded to count value clear 0;
After DM server completes above-mentioned data processing, in the video storage information data table of VM database by the video storage information recording forming after the time aggregation of each video camera.Take two video camera Camera1, Camera2 is example, supposes that these two video cameras start recorded video from 2013-08-2211:00:00, at 2013-08-2215:15:16 because network failure interrupts storage.Then at 2013-08-2215:30:00, recover storage, store 2013-08-2217:00:00 always into, video storage information data table record as shown in table 1:
| Table record ID | Video camera ID | The video slicing time started | The video slicing end time |
| 1 | Camera1 | 2013-08-2211:00:00 | 2013-08-2215:15:15 |
| 2 | Camera2 | 2013-08-2211:00:00 | 2013-08-2215:15:15 |
| 3 | Camera1 | 2013-08-2215:30:00 | 2013-08-2217:00:16 |
| 4 | Camera2 | 2013-08-2215:30:00 | 2013-08-2217:00:16 |
Table 1
User during to VM server retrieves camera video, video camera ID, retrieval time started, the retrieval end time of VM server based on user's input, directly in the video storage information table record of VM server database, inquire about the table record of video slicing time started >=retrieval time started, the video slicing time started <=retrieval end time of this video camera, and all table record packings that satisfy condition are returned to user.
Consider that headend equipment directly deposits video in the networking situation of IPSAN equipment, exist the video storage between headend equipment and IPSAN normal, but the situation that between headend equipment and DM server, network disconnects.Therefore, the present embodiment, when video frequency searching, increases headend equipment and the disconnection of DM server network, DM server is failed effectively to upgrade the protection mechanism of video storage information:
For video frequency searching request, the video of " video slicing end time and the retrieval end time <=DM server current time of this video camera the last item video slicing table record in retrieval time started >VM server database video storage information table record ", DM server will directly be initiated retrieval to IPSAN;
For example: the current time of DM server is 2013-08-2217:30:10.The video frequency searching of the time that user initiates video camera Camera1 by client from 2013-08-2216:50:00 to 2013-08-2217:30:00, and in database the video slicing end time of the last item table record of Camera1 be 2013-08-2217:00:16.For 2013-08-2217:00:17, arrive the video during this period of time of 2013-08-2217:30:00, DM server will directly be initiated retrieval to IPSAN.
After the response of receiving IPSAN, VM can splice the video frequency searching result in the result for retrieval on IPSAN and VM server database, and splicing result is returned to client.
A kind of special circumstances of the present embodiment, in video monitoring system, add new video camera, after this video camera start, start capture video, but due to the up-to-date video storage information table record of this video camera not in video management database, in data management server this locality, do not have yet, now before step 302, also should comprise step:
Judge in local video storage information table record and whether have the video storage information table record that current video camera is corresponding, if had, enter step 302, otherwise the video slicing time started based on current video burst, video slicing end time insert a new video storage information table and are recorded in video management server database, the video storage information table record newly inserting is loaded into data management server this locality, proceeds to step 305.
This step can make to add easily new video camera in system, facilitates the work such as dilatation and network optimization maintenance, even if there is new video camera to add, also can realize easily video storage recording of information.
It should be noted that, for iSCSI, directly deposit, when by headend equipment, to each video camera, the video on IPSAN is realized circulation manifolding, in VM server database, video storage information table record needs automatic synchronization cleaning.The video camera that each is carried out to storage plan, can record the video time index data of earliest time in headend equipment this locality.Therefore, can be according to cycle regular hour (suggestion be usingd 24 hours as synchronizing cycle) on headend equipment, the video time index data of local each the video camera earliest time of preserving of retrieval, and carry out data encapsulation by XML, to DM server, report.XML data format is as follows:
After DM receives above-mentioned notice message, remove in the video storage information table record of VM server database, all table records of " the video time index data of the current earliest time of video slicing end time < (such as " 2013-09-2018:00:20 " in example) " of corresponding video camera, thus realize deleting the automatic synchronization cleaning of the index data of video.
