The Java language exploitation is selected in the concrete realization of the algorithm of software section, agreement, framework for use, thereby the assurance system can be cross-platform, increases stability and standardization.
1, system's composition proposal
As shown in Figure 1, livestock and poultry cultivation process mass data automated processing system of the present invention comprises: acquisition module, and it comprises: environmental variance acquisition module and graphics/audio synchronous acquisition module are respectively applied for and gather environmental variance data and graphics/audio data; Data processing/memory module is used for the data of said acquisition module collection are handled and stored, and it comprises: database and file system; The data sync recovery module is used for said data processing/memory module is carried out the synchrodata scheduling; Inquiry and display module are used to accept the request of the data of a certain moment of user inquiring or time period, and submit to said data sync recovery module; Behind the said data sync recovery module return results, supply the user to check.Wherein inquiry and display module adopt web inquiry and display module.
The environmental variance acquisition module is regularly gathered the data that comprise sensors such as temperature, humidity, carbon dioxide, ammonia, wind speed, illumination automatically, is that index deposits database in the acquisition time; This research is based on the idea that makes image and audio-frequency information collection and particular hardware platform independence; Thereby do not use the SDK kit of video camera; (Java Media Framework JMF) comes constructing system obtaining media data as main model but chosen the Java media framework with advanced media processing capacity; With the media file stored in form, and associated description information is synchronized and stores in the database after image that obtains and the voice data processed compressed; Web inquiry and display module are accepted the request of (or constantly) production data information of a certain date of user inquiring, and submit to synchronous recovery module; The query requests of recovery module response is synchronously carried out the synchrodata scheduling to data processing and memory module, and is returned the result, supplies user web mode to check.
2, image and audio collection and compression scheme
In the whole culture-cycle of livestock and poultry, it is not high that the ground that is left intact directly keeps all video information feasibilities: (1) required storage space is big, and the storage fund cost is high; (2) on the same day different periods, livestock and poultry activity frequent degree significant difference.For example livestock and poultry are very tranquil at night, and the feed stage by day is movable frequent, and continual recording there is no need in one day 24 hours; (3) media file too conference cause inquiry inconvenient, access to netwoks speed is slow.Recording a video file for a long time, breaks down and causes video data damage or losing probability also can raise in the centre.
Based on above analysis, native system is taked following acquisition scheme:
(1) drainage pattern of employing timesharing frequency conversion, the frequency acquisition of AV changes with livestock and poultry activity frequent degree.21 of nights to 5:00 AM was gathered 1 minute in per 1 hour; Daytime the critical activity time point (the crucial frequent activities time of livestock and poultry is relevant with concrete breeding technique, feeding time for example, morning lighting time etc.) gathered 20 seconds data (2 hours altogether) in per 1 minute; Daytime, non-key time point was gathered 1 minute data in per 10 minutes.
(2) audio frequency continuous acquisition, image spacing is captured, and separately preserves in order after audio frequency and the compression of images.Acquisition phase in continuous recorded voice, was whenever captured a pictures at a distance from 2 seconds, further reduced required storage space significantly.Each data file of gathering is named with timestamp, and rationally the compression back is saved in file server corresponding stored path respectively.
(3) compress technique and the compressibility of selection suitable audio and image file.In order on web, to play image and the audio file of gathering glibly, save storage space, media file must be enough little, and still, image after the compression and audio quality also must reach further animal behavior Study of recognition demand.Main flow and compression algorithm have efficiently been chosen on the present network in this research.
Audio compression techniques is selected MP3 (MPEG Audio Layer3); It can be lost under the very little situation in tonequality and be compressed to littler degree to audio files; And also very well kept original tonequality, exactly because the characteristics that volume is little, tonequality is high make MP3 become the synonym of online music.Standard of image compression has been selected JPEG (Joint Photographic Experts Group); It removes redundant view data with the lossy compression method mode; When obtaining high compressibility, can represent and enrich lively image; Though it has lost a part of high frequency spectral line of image, most useful informations can be preserved.
Suppose that the JMF video acquisition parameter that is provided with is following: resolution is 640x480; Use the RGB pattern; The coded format of 24-bit extracts and is about (the different images size according to camera specification, bedding and padding, illumination, livestock and poultry is slightly variant) about 20KB-40KB through ffmpeg instrument compressed images size.The audio sampling frequency that is provided with is 44100Hz, and sound channel is stereo, and sample size is 16bit, and via the ffmpeg compression, the mp3 audio file size that generate 20 seconds is about 370KB.The required storage space of audio frequency that the single audio frequency single camera collected in 1 day and view data is approximately: 226MB-384MB, the data volume in 1 year also only is about about 83-140GB.
3, the synchronous preservation scheme of image and sound
Timesharing frequency conversion drainage pattern as described above; 1 livestock and poultry house (is supposed single camera; Single Mike's situation) image that was collected in 1 day and the quantity of audio files are 4384; The quantity of documents that then gather to generate in 1 year surpasses 1,600,000, and along with increasing of time, hen house quantity, collecting device quantity, the growth of quantity of documents is considerable.If be deposited in all image data in the same catalogue, opening catalogue speed can be very slow.Native system data processing module design acoustic (comprising the xml file) and the image separately multistage catalogue of also automatic realization are deposited, and storage directory is respectively (being example with windows):
E: < year>< month>day>and < hen house number >
E: < year>< month>day>and < hen house number >
What <>lining was represented is the implication of current directory representative.For example: the audio files of No. 2 hen houses that on August 1st, 2011 collected (and gathering the xml file that is generated each time) is saved under the E: catalogue automatically, and image file is saved under the E: catalogue automatically.
According to gathering sequencing, for example generate successively: the single acquisition image file series of 201108111402-001.jpg, 201108111402-002.jpg....
In collection and processing module program process; Designing program generates synchronously a record of having preserved several key messages such as gathering date, hen house number, xml filename, mp3 filename, acquisition time, amount of images, IMAQ interval in the acquisition and recording table of database, with quickening web inquiry velocity.
4, the synchronous web display design of audio frequency picture and environment multi-source data
Native system uses special-purpose flash player to realize the web synchronous playing of image and audio frequency, and what select for use is the imagerotator player among the jw flv player.The each collection and play sequence of the automatic generation of processing procedure meeting: the mp3 audio file of background music for gathering, set of image files and playing sequence are then defined according to the xml file that the imagerotator prescribed form is generated by data processing module.The reproduction time that image sequence only need be set when web calls is consistent with the time interval of images acquired at interval, then can realize the synchronous playing of image and voice data.At broadcast interface, also show the ambient parameter data of corresponding time synchronously.Slow relatively because of the variation of environmental parameter, program provides can regulate acquisition time function at interval as required.Native system is provided with at present whenever gathered an environmental data at a distance from 3 minutes.In the web query display, according to the timestamp of the audio file of playing, system can search the environmental data that the minimum moment of time difference gathers in the database and show synchronously as environmental data.
As shown in Figure 2, image and audio sync collection and treatment scheme in the livestock and poultry cultivation process mass data automatic processing method of the present invention comprise step: S1: the production time stabs; S2: acquisition module initialization; S3: synchronous acquisition audio, video data; S4: judge whether the timer thread time arrives; If then generate video file and close acquisition module, otherwise get back to step S3; S5: compression is preserved to the audio file in the video file, and the abstract image compression is preserved at interval; S6: produce synchronously playing audio frequency and the required xml document of video; S7: acquisition and recording writes database; S8: deletion video file.
Camera and microphone insert acquisition server respectively, as the image of JMF and the capture device of audio frequency.The emphasis of audio frequency acquiring and image is the synchronous acquisition that realizes both.
When each collection began, program at first generated the index timestamp according to current system time, in order to mark audio frequency and image file.For example certain time that begins to gather is: 2011-08-11 14:02, then according to the defined time format of program, timestamp variable timeformat is assigned: 201108111402.
Process flow diagram is realized full automation, and each the collection can be carried out in order: gather, ffmpeg extracts desired data and compression is preserved, the deletion intermediate file, close flow process such as collection, without human intervention.It can periodically be automatically performed according to disposing the acquisition interval that is provided with by task scheduling (windows platform) or crond finger daemon (linux platform) respectively according to the platform difference of disposing.
The cross-platform audio frequency and video scheme of increasing income ffmpeg can realize the synchronous acquisition (reduction synchronously) and the compression preservation of AV.Ffmpeg has comprised the total solution of format conversion and compression audio frequency and video, has comprised advanced audio/video encoding and decoding storehouse libavcodec.What system at first obtained is video, extracts at interval through routine call ffmpeg specialist tools and obtains pictures, and this kind collection is more accurate synchronously than timing pictures that individual images acquired obtained and sound, and realizes compression synchronously easily.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and replacement, these improvement and replacement also should be regarded as protection scope of the present invention.
