Formula and the beneficial effect that should be able to reach is set forth in.
Embodiment one
As it is shown in figure 1, be the video data storage method flow chart in the embodiment of the present invention one, it is specifically located
Reason flow process is as follows:
Step 11, is cached in buffer memory device successively by the video data collected, and wherein, described caching sets
For comprising each data block, the duration of the video data of each data-block cache is preset duration.
For convenience, the executive agent of the video data storage method in the embodiment of the present invention one is referred to as
Video monitoring apparatus.Video monitoring apparatus can be arranged in video monitoring equipment, it is also possible to is separately provided.
In order to ensure the effectiveness that video data stores, the embodiment of the present invention one proposes, and video monitoring apparatus can
Carry out Segment-based caching with the video data that will collect, pre-set the duration of every section of video data, then will
The buffer zone of buffer memory device is divided into each data block, and one section of video data of each data-block cache is the most each
The duration of the video data of data-block cache is the above-mentioned duration (being properly termed as preset duration) pre-set.
Such as, above-mentioned preset duration is 15 minutes, as in figure 2 it is shown, drawn the buffer zone of buffer memory device
It is divided into N number of data block, the duration of the video data of each data-block cache to be 15 minutes.
When video monitoring apparatus is started working, starting caching thread, caching thread is by video monitoring apparatus collection
To video data be cached to successively in buffer memory device.Wherein, caching thread is with N number of data block as circulating cycle
Phase, the video data sequential loop collected by video monitoring apparatus is cached in each data block, concrete,
As it is shown on figure 3, the caching first paragraph video data that first collected by video monitoring apparatus of thread is cached to the
In 1 data block, the collect the 2nd section of video data is cached in the 2nd data block ..., depend on
Secondary analogize, the N+1 section video data collected is cached in the 1st data block, covers the 1st section and regard
Frequency evidence.Wherein, the duration of every section of video data that video monitoring apparatus collects is preset duration.
Step 12, after receiving the fault alarm signal that monitored target device sends, determines and receives institute
State the data block at video data place corresponding to the time point of fault alarm signal.
When the target device (such as wastewater treatment vehicle) that video monitoring apparatus is monitored breaks down, this mesh
Marking device can send fault alarm signal to video monitoring apparatus, to indicate video monitoring apparatus to carry out video counts
According to storage.Video monitoring apparatus can be using the time point receiving fault alarm signal as the mesh monitored
The time point that marking device breaks down.
In prior art, when video monitoring apparatus is started working, start caching thread and storage thread, caching
Video data is cached in buffer memory device by thread successively, and meanwhile, storage thread is by the video in buffer memory device
Data store in storage device successively.And the embodiment of the present invention one proposes, video monitoring apparatus is started working
Time, starting caching thread, do not start storage thread, storage thread is to be triggered by fault alarm signal to open
Move, after video monitoring apparatus receives the fault alarm signal that monitored target device sends, confirm
Target device now there occurs fault, and therefore video monitoring apparatus starts storage thread, performs storage video counts
According to flow process, i.e. the storage of video data is to be triggered by the fault of target device.
In the embodiment of the present invention one, when video data is cached in buffer memory device by video monitoring apparatus successively,
Current video file control information can be recorded, wherein, the current video file control information of record comprises
The mark of the data block at the video data place of current cache, such as, video monitoring apparatus will gather the 1st
When section video data is cached in the 1st data block, the data block at the video data place of current cache is
1st data block, just comprises the mark of the 1st data block in current video file control information.
After video monitoring apparatus receives fault alarm signal, starting storage thread, storage thread first obtains works as
Front video file controls information, the mark institute of data block that then will comprise in current video file control information
Corresponding data block, confirms as receiving the video data place that the time point of described fault alarm signal is corresponding
Data block.Such as, current video file control information comprises the mark of data block 1, therefore can be true
Think that the data block receiving video data place corresponding to the time point of fault alarm signal is data block 1.
Wherein, the data block at video data place corresponding to the time point of described fault alarm signal is received also
It is properly termed as current data block, in the following description, all represents the data determined with current data block
The data block at the video data place of block, i.e. current cache.
Step 13, in the data block that will determine, the video data of caching stores in storage device.
In the embodiment of the present invention one, video monitoring apparatus can also be further at current video file control information
The video initial time dot information that middle record current data block is corresponding, such as, video monitoring apparatus is by collection
When 1st section of video data is cached in the 1st data block, current data block is the 1st data block, the 1st
Video start time point corresponding to individual data block is the start time point of the 1st section of video.
Video data in the time period that target device breaks down may be buffered in a data block, now
In the data block that video monitoring apparatus will be determined, the video data of caching stores in storage device.
Additionally, the video data in time period of breaking down of target device is likely to be buffered in two data blocks
In, in order to ensure the integrity of the video data of storage, the embodiment of the present invention one proposes, at storage video counts
According to time, can first judge to receive time point and the current video file control information of described fault alarm signal
In time interval between time point corresponding to the video initial time dot information that comprises whether more than setting
Time interval threshold value, if judging more than the time interval threshold value set, then to show that target device breaks down
Time period in video data may be buffered in current data block and next data block, therefore ought
In front data block and next data block, the video data of caching stores in storage device, if judging not
More than the time interval threshold value set, then show that the video data in the time period that target device breaks down can
Can be buffered in current data block and a upper data block, therefore by current data block and upper data
In block, the video data of caching stores in storage device.
Such as, the video data of each data-block cache time a length of 15 minutes, the time interval threshold of setting
Value is 7 minutes, say, that if the time point receiving fault alarm signal is delayed at current data block
In first 7 minutes of the time period that the video data deposited is corresponding, then storage current data block and a upper data block
Interior video data, receives the video data that the time point of fault alarm signal is cached at current data block
In latter 8 minutes of corresponding time period, then storage current data block and the video data in next data block.
During above-mentioned storage video data, the video data that target device is cached at current data block
It may happen that repeatedly fault in the corresponding time period, in order to avoid video data repeats the situation of storage, joint
Saving the memory space of storage device, the embodiment of the present invention one proposes, and video monitoring apparatus can also exist further
Current video file control information records the preposition storage mark of video and the rearmounted storage mark of video, now when
It is as shown in table 1 that front video file controls information:
Table 1
| The video initial time dot information that current data block is corresponding |
| The mark of current data block |
| …… |
| The preposition storage mark of video |
| The rearmounted storage mark of video |
If video monitoring apparatus judges the time point receiving fault alarm signal and current video file control
Time interval between the time point that the video initial time dot information that comprises in information processed is corresponding is more than setting
Time interval threshold value, the most first check the rearmounted storage mark of the video comprised in current video file control information
Set the most, if non-set (value of storage mark is 0), then shows the frequency that current data block is cached
There is not fault according in the corresponding time period, therefore can perform current data block and next number
Store the step in storage device according to the video data of caching in block, and rearmounted for video storage mark is put
Position, if set (value of storage mark is 1), then shows at the video data pair that current data block is cached
Fault was had occurred and that, say, that video monitoring apparatus has indicated storage thread in the time period answered
The operation of the video data cached in performing storage current data block and next data block, the most now may be used
No longer to perform to store the operation of video data.Such as, the time point of fault alarm signal is received currently
In latter 8 minutes of the time period that video data that data block is cached is corresponding, if the rearmounted storage mark of video is not
Set, then storage current data block and the video data in next data block, if the rearmounted storage mark of video
Set, does not the most perform to store the operation of video data.Such as, the time point of fault alarm signal is received
In latter 8 minutes of the time period that the video data that cached at current data block is corresponding, if the rearmounted storage of video
The non-set of mark, then storage current data block and the video data in next data block, deposit if video is rearmounted
Storage mark set, does not the most perform to store the operation of video data.
If video monitoring apparatus judges the time point receiving fault alarm signal and current video file control
Time interval between the time point that the video initial time dot information that comprises in information processed is corresponding no more than sets
Fixed time interval threshold value, the most first checks the video comprised in current video file control information preposition storage mark
Will set the most, if non-set, then shows the time that the video data that cached at current data block is corresponding
There is not fault in Duan, therefore can perform caching in current data block and a upper data block
Video data stores the step in storage device, and by preposition for video storage mark set, if set,
Fault was had occurred and that, the most just in then showing the time period that the video data cached at current data block is corresponding
Being to say, video monitoring apparatus has indicated storage thread and has performed storage current data block and upper data
The operation of the video data of caching in block, the most now can no longer perform to store the operation of video data.Example
As, receive the time that video data that the time point of fault alarm signal cached at current data block is corresponding
In first 7 minutes of section, if the non-set of the preposition storage mark of video, then storage current data block and a upper number
According to the video data in block, if video preposition storage mark set, the most do not perform to store the behaviour of video data
Make.
The embodiment of the present invention one proposes, if current data block changes, then and current video file control information
Needs are updated, wherein, update current video file control information time, can by update before current
The value of the rearmounted storage mark of video comprised in video file control information is assigned to the current video literary composition after updating
The preposition storage mark of video comprised in part control information such that it is able to avoid video data to repeat the feelings of storage
Condition, saves the memory space of storage device further.Such as, the 1st section gathered is regarded by video monitoring apparatus
Frequency is according to when being cached in the 1st data block, and current data block is the 1st data block, at the 1st section of video
Latter 8 minutes in, target device there occurs fault, therefore video monitoring apparatus store the 1st data block and
The video data of caching in 2nd data block, and by rearmounted for video storage mark set (storage mark
Value is 1), when the 2nd section of video data gathered is cached in the 2nd data block by video monitoring apparatus,
Current data block is the 2nd data block, and current video file control information needs to be updated, now, and can
With replicate update before current video file control information in the rearmounted storage mark of video value to renewal after
Current video file control information in the preposition storage mark of video, say, that work as forward sight after renewal
In frequency file control information, the value of the preposition storage mark of video is 1, then target device was sent out at first 7 minutes
