Fig. 1 is data from multiple sources treatment system structural representation in Vessels Traffic System of the present invention, and as shown in Figure 1, the present embodiment system comprises:
Data memory module 101, for data from multiple sources timing acquiring, and described data from multiple sources is converted to stream format data, search index file is set up according to described stream format data, described stream format data stored according to stream media format, described data from multiple sources comprises radar video data, merges track data, system alarm event data and voice data;
Further, described data memory module, comprising:
Data receipt unit, for resolving data from multiple sources packet head, determining the type of described data from multiple sources, determining corresponding memory according to described data from multiple sources type, resolve described data from multiple sources bag content, and described data from multiple sources bag is stored in the buffer;
Data saving unit, for reading in described buffer memory the described packet stored, and generates data block, by described data block write respective file, changes the index information that described data block is corresponding, empties in described buffer memory the described packet stored.
Specifically, data memory module is divided into two parts: data receipt unit and data saving unit.As shown in Figure 2, data receipt unit, after receiving data from multiple sources, resolves this data from multiple sources packet head, the type of this data from multiple sources is determined with this, and determine corresponding memory according to the type, then resolve this data from multiple sources bag content, and this data from multiple sources bag is stored in the buffer.
As shown in Figure 3, data saving unit is that hard disk reads this data from multiple sources by timer clocked flip from buffer memory, and can setting-up time threshold value, judges whether the time that this packet is corresponding exceedes this time threshold, as exceeded, then unlatching asynchronous thread deletes the data between this time threshold, if do not exceed, then and reading cache data, generate data block, by this data block write respective file, change the index information that this data block is corresponding, and empty the packet stored in this buffer memory.The present embodiment data memory module supports the data memory format that multiplex data stream is play, and supports the playing function of similar DST PLAYER class.
Data retrieval module 102, for the playback request quick-searching index file according to client, searches data storage location according to described index file and described playback request, and rapid extraction data message;
Further, described data retrieval module, specifically for:
Receive playback command, and according to described playback command determination data block search argument;
Judge whether the time corresponding to data cached bag meets threshold time, if so, then in described data cached bag, retrieve described data block, if not, then retrieve described data block again after being loaded into by described data cached bag;
The described data block retrieved is sent to data transmission blocks.
Specifically, as shown in Figure 4, the data retrieval module of the present embodiment achieves quick-searching, and rapid data collection sends fast, and the playback request sent from client returns time of delay to data can in 2S.

Data memory module achieves scene writing function, and this scene writing function is as follows:
Radar video data record: receive from MULTISENSOR INTEGRATION processing server send radar video data, according to information such as radar station numberings, separately store the video data of each radar station, storage be radar scanning line pressure contracting after data.
Merge track data record: the track data receiving the fusion sent from MULTISENSOR INTEGRATION processing server, the data content of storage should be that the track of fusion is by the binary stream after protocol buffer serializing.
System alarm logout: receive the alert event sent from MULTISENSOR INTEGRATION processing server, the content of storage is send to embrace the binary data stream of alert event after protocol buffer serializing.
Audio data recording: receive the voice data exported from audio collection card, convert wav form to, store according to wav form.
Data retrieval module, data transmission blocks achieve scene playback function, and this scene playback function is as follows:
Radar video data readback: retrieve radar video data according to the playback duration section that client sends from local radar record data, obtain radar scanning line data according to result for retrieval timing to send to request playback client, send the radar scanning line data that data are compression.Scan a UDP message bag according to every bar during transmission to send.
Merge track data playback: record from this locality note track the track data retrieving fusion data according to the playback duration section that client sends, track data binary stream is obtained according to result for retrieval timing, multiple track binary data stream forms a UDP bag and sends, and track data per second carries out UDP transmission several times.
System alarm event replay: retrieve alert data according to the playback duration section that client sends from local alarm logging data, timing obtains alert data binary stream, because alert data is less, the data that timing obtains can use a UDP bag to deliver.
Audio data playback: the playback duration section retrieve audio data from local audio record data sent according to client, timing obtains the audio data stream of fixed length size, audio data stream is delivered according to a UDP message bag per second.
Playback controls mainly comprises beginning, time-out, stopping, acceleration, deceleration, the dragging of playback progress.
Start playback: the initial time sent according to client, carry out data retrieval process, send playback of data to client.
Suspend: the time-out request sent according to client, suspend data retrieval, playback of data wouldn't be sent to client.
Stop: the stopping request sending according to client, cancel data retrieval process, stop the process sending data to client.
Accelerate: the acceleration request sent according to client, according to acceleration speed, interval obtains data and carries out data transmission, does not carry out acceleration process for voice reproducing.Acceleration is respectively 1,2,4,8,16,32,64X.
Slow down: according to the deceleration request of client, lower interval data and obtain process, slowing down minimumly is kept to 1 speed, can not decelerate to below 1 speed.
Playback progress drags: the schedule variance request sent according to client, according to NEW BEGINNING time point, re-start data retrieval and process of transmitting, the data of transmission are the data of new setup times point.
Change played data type: the change data playback type requests sent according to client, open or close the playback operation of a certain class data.
Change audio frequency and play passage: play passage change request according to the audio frequency that client sends, determine play the voice data of which passage or close the voice data of which passage.
The embodiment of the present invention, achieves the data memory format supporting that multiplex data stream is play, can support the playing function of similar DST PLAYER class.Adopt data retrieval mechanism, realize quick-searching, rapid data collection, send fast, send playback request from client and return time of delay within 2s to data.Client can be carried out similar streaming media playing and be carried out playback controls, and playback operation is without delay, and user just can check playback of data fast without the need to waiting as long for.After client selectes playback duration section, can playing at once, without postponing, not needing to wait for.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
