Fig. 2 is the functional block diagram of main frame 1 of the present invention, we can see that main frame 1 comprises central processing unit 11, internal memory 12, gps satellite locating module 13, warning sensing module 14 and can insert the wireless communication module 15 of SIM card, also comprises a picture processing module 16 among the figure.Picture processing module 16 includes jumbo picture storage module 161, center picture processing module 162, described picture storage module 161 includes the pictorial information memory module 1611 that grouping is stored, image cache module 1612 in order to the pre-pictorial information of deleting of interim storage, described center picture processing module 162 be provided with can retrieving image information picture retrieval module 1621, described picture processing module 16 is connected with central processing unit 11 pictorial information of needs transmission is transmitted by wireless communication module 15, and described wireless communication module comprises that the transport layer of GPRS module 151 and CDMA module 152 and above-mentioned module adopts UDP or Transmission Control Protocol to transmit.Described camera head shot picture information with according to the mode packet memory of date classification in picture storage module 161.
More than be the hardware components of system, tell about in detail how to carry out high capacity storage and management during system works below in conjunction with embodiment.With the system that is arranged on the taxi is example, takes pictures when turning under the taxi empty wagons board, takes pictures when perhaps being used for the passenger vehicle on-board and off-board and carries out the passenger flow management.The photo that camera head takes can store pictorial information memory module 1611 by date into.The method of the preservation of picture is to preserve according to the date, i.e. picture within a period of time is kept in the sub-directory, and directory name is based on the date name.Preserving a sub-directory with one day is example, if subdirectory name is " 070927 ", then represents on September 27th, 07.All picture sub-directory unifications are placed under the picture composite catalog, do not have alternative document under the picture composite catalog, have only each date sub-directory.Like this camera head picture shot every day can be kept at automatically with the corresponding sub-directory of shooting date under.
In addition, picture storage module 161 also stores the information relevant with pictorial information, as excites the event type of the action of taking pictures, the moment of taking pictures, positional information, the resolution of photo, quality are taken passage (during multi-cam), and are recorded on the filename of pictorial information in the mode of coding.Below be that example describes with the name of certain picture.
For example: picture name " 0056301d_192105_E118054627N24561234_1_212.jpg ", be explained as follows: the index number of " 0056301d " expression photo, here show with 16 system numerical tables that maximal value is the ffffffff (promptly 4294967295 of 10 systems) of 16 systems.Every take finishes a photo, the print reference value of progressively increasing a time.Print reference arrives after the maximal value, recycles from 1 open numbering again.If calculate with every photo 3K byte, it is G more than 10,000 2 thousand that 4294967295 photos take up space, obviously for the such embedded device of car-mounted terminal, so big space can not be arranged for storage, so, can be because of not the recycling of index number, cause photo in the terminal situation of same index numbering to occur, because when storage space is full, terminal will be old photo deletion." 192105 " expression is taken pictures constantly, is 19: 21: 05 here.Positional information when " E118054627N24561234 " expression is taken pictures is 118.054627 ° of east longitudes here, 24.561234 ° of north latitude." 1 " expression event type of taking pictures, be decided to be approximately here " plunder and report to the police " (other types are: 2, burglar alarm; 3, turn under the empty wagons board; 4 ...)." 212 " represent channel number, photo size, photographic quality respectively.Channel number is decided to be 1～4 approximately, represents 4 different passages; Photo size is decided to be 1～3 approximately, represents that respectively resolution is 176 * 144,352 * 288,720 * 576; Photographic quality is decided to be 1～3 approximately, represent respectively low (Jpeg compression quality coefficient 30), in (quality coefficient 50), high (quality coefficient 80)." .jpg ": expression is the picture of jpeg format.Like this we are just clear all to pictorial information.
The car-mounted terminal long-time running must have been preserved a large amount of photos, and untimely deletion is just easy of capacity limit, and can not preserve the photo of new shooting, so must the comparison film catalogue manage, in time deletes old photo, reclaims the space.Therefore an image cache module 1612 is set is used for storing the pictorial information of pre-deletion.System sets a photo total space predetermined value for the memory capacity of pictorial information memory module 1611, such as the 100M byte.Before taking pictures at every turn, it is the memory space that center picture processing module 162 detects the picture composite catalog, when the memory space that detects described pictorial information memory module 1611 when center picture processing module 162 surpasses this predetermined value, automatically the pictorial information under the oldest catalogue of described 1611 following dates of catalogue of pictorial information memory module is moved to described image cache module 1612, reexamine after the deletion, if taking up space, picture still surpassed predetermined value, then continue catalogue the oldest of deletion, detect the low memory of pictorial information memory module 1611 in predetermined value up to center picture processing module 162.Content in the image cache module 1612 can be set the time limit, and overstepping the time limit is deleted automatically, deletes All Files automatically if has expired in the space of image cache module 1612.
In general, photo under date sub-directory all can have much, turn over the empty wagons board with taxi takes pictures and is example at every turn, probably have every day about 100 times, during shooting if use the photo of inferior quality, minimum resolution, file size uses 2 passages to take pictures simultaneously about the 3K byte, and then the photo capacity under sub-directory is 3K * 2 * 100=600K.When reclaiming the space, whole photos of a sub-directory of disposable deletion, the space that can reclaim about 600K just, so next recovery space, will wait until about 1 day after.Like this, the action of deletion is not frequent, simultaneously the photo files of having preserved yet as much as possible.
Because photo is to divide sub-directory to preserve on the branch date, and the photo name write down the information such as event type of photo, therefore, can retrieve needed picture according to the date of pictorial information and the relevant information of pictorial information by picture retrieval module 1621.According to time or event condition retrieval photo, such as, retrieval time section 07.09.258:00:15 ~ 07.09.2615:20:00, event type is the photo of " plunder and report to the police ", the method of retrieval is exactly at " 070925 " and " 070926 " 2 sub-directories, searches the photo that event type character in the photo name is " 1 ".So just can retrieve our needed pictorial information.
Below we say in conjunction with the embodiments, describe high capacity in detail and how to transmit by wireless communication module 15 as sheet.Transmission network can utilize existing civilian GPRS network, or cdma network carries out data communication.During communication, debit both sides use Socket to communicate, and transport layer protocol can use UDP, also can use TCP.Consider the GPRS network transmission quality not as cable network, the image data that data volume is bigger is easy to generate the packet loss phenomenon when transmission.If use TCP communication, in case certain bar tcp data can not correctly transmit, because the affirmation of TCP-re-transmission controlling mechanism, can retransmit always, cause follow-up data to transmit, occur stopping up, thereby reduce networks efficiency, influence the communication of other business datums, therefore suggestion uses UDP to communicate.
In the transmission course, the pictorial information data are carried out the subpackage transmission.The subpackage here is not meant the datagram of IP layer, and is meant in application layer the picture data subpackage is transmitted.The photo files minimum a few K bytes are also arranged, maximum have tens K bytes, is subject to the general characteristic of network, can not be encapsulated as a data frame transfer.Therefore, photo can be divided into plurality of data bag (last bag of photo allows to be less than fixed value certainly) by fixed byte, be 512 bytes to the maximum such as bag of regulation, the photo of such 3072 byte-sized just is divided into 6 bags, and the photo of 3272 byte-sized just is divided into 7 bags (size of noting last bag of this photo this moment just has only 200 bytes).Photo subpackage transmission facilitates and transmits control.
When terminal system sent pictorial information to service centre, transmit leg sent photo, and the take over party must reply, and to prevent loss of data, causes the imperfect of photo.But transmission is replied, and does not need every transmission 1 bag all to require the take over party to be replied, and efficient is too low like this, but transmits a collection of bag, just requires the take over party to reply.This mode of in batches replying is exactly the windowing mechanism of picture transmission.What adopt here is fixed window size, such as window fixed of regulation comprise 16 bags (certainly, if last window of photo, or because of receiving the imperfect window that retransmits, wrap number and allow to be less than the window fixed size).
Be the example and the detailed description thereof of host-host protocol below.
