Description

Catches through wireless data link reportedly send

Technical field

The present invention relates to data and transmit the field.More specifically.The present invention relates to send the data of catching from remote equipment through wireless data link.

Background technology

Data capture device comprises camera, recorder, data logging machine and video camera.These equipment are used the analog storage media such as film, paper or tape to hold usually and are caught data.The information that the data of catching can be expressed as follows and so on: the record of static or mobile image, the sound that is write down or some other observation phenomenons such as seismic activity or meteorological condition.

A problem using above equipment to occur is the finite capacity of storage medium.Therefore, want that the user who writes down memories such as journey, vacation, party, graduation must obtain and carry the photosensitive film of multireel (under the camera situation) or a large amount of tape (under the video camera situation); Otherwise the user understands the danger of using light memory capacity.In many cases, can not accurately know to need how many storage mediums to write down particular event in advance.And, in case will contain in media (for example film or the tape) slave unit of catching data and take out, make media (and data of holding) suffer to lose irretrievablely or damage probably for renewing media.

In many cases, can use digital media to hold the data capture device of catching data.For example, Fig. 1 illustrates the block diagram of digital camera.Imageing sensor can be charge-coupled device (CCD) or CMOS (Complementary Metal Oxide Semiconductor) (CMOS) transducer.Imageing sensor also can comprise the support circuit of Signal Regulation (as: automatic exposure control, anti-control, black and white balance and so on of defocusing).Signal is sent to processor coding, and the task of this processor can comprise the compression scheme of application such as JPEG (Joint Photographic Experts Group, ISO/IEC standard I S 10918-1,10918-2,10918-3:ITU-T T.81,7.83,7.84) and so on.The digitlization that betides the preceding picture signal of coding can or be inserted digitizer and finish by transducer, processor.

Except that these Processing tasks, processor is also carried out the storage administration task relevant with picture signal being stored to memory element.To capacity applications in low (as: picture that the consumer uses), memory element be as memory stick (Sony of Tokyo), smart media (as, as the web edition defined of date smart media electronics, physics, physical format and logical format specification that to be on May 19th, 1999 published by Japanese SSFDC forum) or the flash RAM equipment of compact flash memory (being positioned at the CF+ of compact flash memory association of Palo Alto of CA and the revised edition 1.4 of compact flash memory specification) specification.To volume applications (as: picture of professional application), can use small-sized Winchester hard disk (by IBM Corporation's exploitation of the White Plains that is positioned at New York).

FPDP is supported the serial link under RS 1 or USB (USB) the association instrument.The data of this port carrying from memory to external personal computer are to browse, file, to duplicate etc.As discussed below, FPDP also can be from carrying out application program receiving control information on the PC externally to revise the camera parameter such as compression ratio or to wipe memory element.

Camera user is by user interface and camera reciprocation, and user interface provides control information to processor.For example, user interface comprises that typically shutter discharges the information that is received by imageing sensor to catch.In some cameras, but user's input pickup or processing parameter are to revise camera operation.For example, the user can change compression ratio (with picture quality is that cost exchanges maximum image memory capacity for, and vice versa), or checks captured images (if camera comprises image viewer) or regulate photoflash operation or other exposure values.In many cases, these parameters can be imported by external personal computer, because user interface generally includes the software application that runs on the PC and communicate by letter with camera through FPDP.

Be subject to the capacity of analog storage media as the analogue data capture device, digital data capture device also is subject to the capacity of memory element.In case existing media does not have the space, unless the user must cover available data or off-stream unit until can unload these data have extra media can with or have the adaptive PC of putting of ECDC to can be used to unload the data of storage.Even have extra media or such computer to use, the user must stop record data and finish until changing media or data download and so on cumbersome task.As the analog storage media, in case digital storage elements is taken out from camera, this media and the data of holding thereof will be easy to lose or be impaired.

Summary of the invention

In the equipment as one embodiment of the invention, configuration and assembling control logic piece are to receive the data of being caught.The data of catching can mainly comprise the Any Digit data flow that needs record.Configuration and assembling storage element stores are caught data, and configuration and assembling transmitter are caught data to send by wireless data link.Further configuration and assembling transmitter begin such emission to respond at least one judgement, judgement relate at storage threshold and to small part whether exist between the value of catching data volume that is stored in the memory element predetermined relationship (as less than, equal and/or greater than).

Embodiment

As shown in Figure 2, establishing each and 100 comprise and receive the control logic piece 110 catch data according to one embodiment of the invention.Control logic piece 110 can comprise one or more microprocessors, microcontroller or other such as application-specific integrated circuit (ASIC) (ASIC) array of logic elements and/or carry out in a such array or the one or more processes on a plurality of array.Be derived from the application of above-mentioned imageing sensor and image processor catching data, control logic piece 110 and image processor can be used as and be executed in the process that (as: is executed in different time and/or the varying environment) on the identity logic element arrays and realize.

Attention: catch data and be not necessarily limited to view data.For example, catch data and can comprise digital audio-frequency data.And, catch data and can comprise arbitrarily other data flow: as, by the data that a testing equipment (as: spectrum analyzer, seismic detector etc.) produces, these equipment records the data of information of at least one relevant observation phenomenon.Such phenomenon can relate to natural conditions (the one or more weather conditions such as temperature, humidity or cloud density) or artificial condition (such as the decline performance of radio communication channel).Summary is got up, the data of catching can comprise the Any Digit data flow of needs record, and this digital data stream has the characteristic (as: timing value consistent with the characteristic of memory element 120 and the signal of one or more voltage levels are arranged) that is suitable at least temporarily being stored in the memory element 120.

In the application of catching data one or more processing operations of experience (such as digitlization, coding and/or compression) before being received by control logic piece 110, control logic piece 110 and data processor can be used as the process that is executed in (as carrying out in different time and/or varying environment) on the identity logic element arrays and realize.Providing buffering between transducer and processor and/or between the processing stage of one or more.It is desirable to, control logic piece 110 is from buffer but not directly from providing transducer, converter or the processor reception of catching data to catch data.

Control logic piece 110 is also controlled and is caught the storage of data to memory cell 120.For example, control logic piece 110 can make as required and catch data and obtain buffering or reconfigure (for example, flowing to parallel data stream from serial data) so that catch the characteristic of characteristic (such as data rate and/or highway width) the coupling memory element 120 of data-signal.Control logic piece 110 also can with catch data be formatted as be suitable for being stored in the memory element 120 also/or be convenient to file, bag or other type of data structure of later retrieval.For example, control logic piece 110 can make catch data as file storage in the readable bibliographic structure of operating system such as MS-DOS (being arranged in the Microsoft of the Redmond of WA), EPOC (being positioned at the Symbian of London) and/or Linux.Perhaps, control logic piece 110 can make and catch data and store as the bag that fixing or variation length are arranged that is suitable for according to the transmission of predefined communication protocol such as Internet protocol (IP).In another example, control logic piece 110 can to catch data add markers or other information also/or can be before data be caught in storage to its encryption, encode or mark.

Memory element 120 can be any non-volatile random access storage (RAM) equipment.In example embodiment, memory element 120 is the flash RAM equipment that meets specification such as CompactFlash, SmartMedia or MemoryStick.That other non-volatile rams that can be elected to be memory element 120 comprise is magnetic resistance, magnetic, magnetic tunnel-junction (tunneling junction) or ferroelectric RAM.Perhaps, memory element 120 can be miniature Winchester (being a hard disk) driver.Memory element 120 even can be volatibility RAM equipment, for example semiconductor equipment such as dynamic or static RAM (SRAM).In general, memory element 120 can be the memory element that allows arbitrary access arbitrarily and meet the size, speed and the power consumption constraints that can be applicable to particular implementation.

In another embodiment, memory element 120 can be that SIM (subscriber identity module) blocks or other have the RAM part of " smart card " of additional storage and/or disposal ability.In the case, all or some smaller portions of control logic piece 110 also can be integrated on the smart card.Such configuration can save in the handheld device the space also/or reduce producing cost by being combined as single card to the support of multi-functional (as: User Recognition and/or checking, telephone service configuration).In addition, such interface can provide a kind of software easily and/or firmware upgrade mechanism.

Catching in the equipment of data by cellular phone link transmission as described below, the one or more telephone numbers (and the relevant parameter such as access code or password) that such configuration also can utilize the telephone service tenability of smart card will be used for data and transmit are pre-programmed into card.For being easy to programming, can be stored in information on the smart card according to the document directory structure tissue.

The other function that control logic piece 110 provides is protection " pending data " (is stored in the memory element 120 but do not transmit as yet catch data).For example, control logic piece 110 can prevent that data from writing the zone of the memory element 120 that contains pending data.Such protective capability can be used such as realizing with the signal lamp of each part correlation of memory element 120 or the mutual exclusion the mark (or be expressed as " mutex ") mechanism.In another example, can in memory element 120, realize this ability at least in part.

In example embodiment,, set (or " locking ") mutex when catching data when being stored to the counterpart of memory element 120.When transmitting data subsequently when being used to transmit (or retrieve data), (or " opening " or " the removing ") mutex of resetting.When having set mutex, data just cannot be stored to this part of memory element 120.

Fig. 3 illustrates the use operation of the suitable mutual exclusion mechanism of the flow chart of the part of a method according to an embodiment of the invention.In task P110, receive the data block (for example :) of catching from transducer or converter, processor or buffer.(can select the data block size according to following factors: the one or more parameters of the architecture of memory element 120 or form, the capacity in intermediate storage stage, compression algorithm or other data processing tasks, and/or the structure of used host-host protocol on the wireless data link).In task P120, obtain the element address of memory element 120 stored pieces.This address obtain can be by the discrete cell in the access indication memory element 120 (for example, initial cell or catch the unit that data are stored to recently after that unit) pointer, table or similar storage administration structure realize.In task P130, check the state of the mutex of corresponding selected memory element.If mark is open (that is: do not exist in this unit the data that do not transmit), then catches data block and be stored in task P140.If mark is inaccessible, then suspend (maybe may cancel) storage operation.In the example of Fig. 3, it no longer is inaccessible until mutex that task P130 repeats (suspended task P140).In task P180, set mutex, thereby protect pending data.

Task P140 or P180 also can comprise the renewal to the pointer or the table of access among the task P120.In addition, task P140 can differently with the example of Fig. 3 provide suitable protection to treat deal with data with P180.For example, task P140 is limited to only appearance when obtaining permission (giving) by control logic piece 110 and/or memory element 120.In this case, it is desirable to before the storage data, set mutex, (as: make and allow to surmount mutex).

One suitable construction of memory element 120 is round-robin queue or " loop buffer ".Above-mentioned mutual exclusion mechanism can be included in such enforcement.In example arrangement, keep at least two pointers in formation: 1) " the storage pointer " and 2 of next memory cell that data can use caught in the indication storage) indication remains " the transmission pointer " of next memory cell of deal with data.

But control logic piece 110 also the two memory buses of ruling simultaneously data being deposited to memory element 120 with from memory element 120 retrieve data.In this way, the data that transmitted by transmitter 130 can be with a memory bus (by control logic piece 110 and/or transmitter 130) retrieval, and while control logic piece 110 is deposited data to memory element 120 by another memory bus.In optional embodiment, memory element 120 can have two or more ports, and control logic piece 110 and/or transmitter 130 can be through a port directly from memory element 120 retrieve data like this, and control logic piece 110 is through another port storage data simultaneously.Such structure can be used to make retrieval and store tasks to carry out in fact independently of each other.

Transmitter 130 transmits this information from memory element 120 reception information and by wireless data link.Data link can be a dedicated wireless link, for example, and satellite uplink or down channel.In another embodiment, data link can be the part such as the commercialization net of cellular radio network.In another embodiment, data link can be the Radio Link in the WLAN, or meet Bluetooth protocol ( Www.bluetooth.comOn the specification of its 1.0 version is arranged) or the Radio Link or the infrared link of other agreements.In the example application of such embodiment, catch data and can be sent near PC by data link.

Can select one or more incidents to start from memory element 120 retrievals from several incidents catches data and is transmitted this task by wireless data link.In one implements, this task is to cause according to the use level of memory element 120: for example, pending data volume in being stored in memory element 120 (perhaps, the memory space in the current memory element 120 that can be used to store pending data) is when reaching predetermined threshold or " watermark ".Definition that this watermark can data unit (as: 10 megabits, 400 etc.), or the percentage (as: 75%) of press the total capacity of memory element 120 defines.Perhaps, when idle (as: the log-on data is not caught) scheduled time slot of equipment and the place's for the treatment of data and before when being stored in the memory element 120, but the retrieval of solicited message and transmission.Perhaps, the retrieval of information and transmission can take place according to scheduling (as: during the period is used on the non-peak of commercial data link) at least in part.Perhaps, according to judging that the current data link-quality reaches or exceeding predetermined threshold and the place's for the treatment of data are stored in the memory element 120 at present, can start retrieval and this task of transmission information.

Except that above-mentioned task, control logic piece 110 can be carried out from memory element 120 retrievals and catch data and be sent to reflector 130 subsequently to send this task by wireless data link.Perhaps, control logic piece 110 can participate in this task than restricted manner (as: allowing transmitter 130 access memory elements 120 by the two memory buses of ruling).Or transmitter 130 can be carried out from memory element 120 and retrieve participate in directly (as: the above-mentioned dual-port storage system) of catching the task of data and need not control logic piece 110.

Fig. 4 illustrates the flow chart according to a method of one embodiment of the invention.As above-mentioned, in task P110 and P120, receive the address of catching data block and obtaining memory cell respectively.In task P150, the use level of check memory element 120.If judge to use level to be high (as: data volume to be located reach or exceed predetermined threshold or watermark), judge in task P160 then that the transmission task is current whether carrying out.If the task that do not send is being carried out, then in task P170, start the transmission task.After this, if or judge to use level be low, then in task P130 and P140 according to the mutex state storage data block of correspondence, and in task P180, set mutex.

Fig. 5 illustrates the flow chart of the transmission task that starts among the task P170 for example.In task P210, obtain and contain the address that waiting of will transmitting located the memory cell of data.This address obtain be by the discrete cell in the access indication memory element 120 (for example, initial cell, or retrieval recently wait to locate that unit behind the unit at data place) pointer, table or similar storage administration structure.In task P220, treat data from selected memory cell retrieval, and in task P230, transmit these data.In some implementations, institute's data retrieved can obtain mark, timestamp and/or encryption or coding before transmission.For example, digital signature can be attached to each image or frame of video with verification reliability and/or capture time.

In task P240, remove the mutex of corresponding selected memory cell.In exemplary application, the success that task P240 is delayed to the transmission in task P230 has obtained verification.Task P230 or P240 also can comprise the renewal to the pointer or the table of access among the task P210.

In task P250, the use level of retrieve stored element 120.If judge to use level to be high (as: data volume to be located reach or exceed predetermined threshold or watermark), then iterative task P200, it is desirable to, by in task P150 and P250, using different watermarks to introduce degree of hysteresis.For example, the repetition of task P200 can proceed to memory element 120 and no longer remain to be located data.

The speed of the wireless data link that uses according to the speed of catching data that is received by control logic piece 110, by transmitter 130 and/or the speed of control logic piece 110 and memory element 120 just may use equipment 100 realizations to catch and transmit the continuous data stream that size exceeds the capacity of memory element 120 at least in part.

Figure 19 illustrates an example of the protocol scheme of the operation that is used to carry out system shown in Figure 180.Set up the FTP link, an end of storehouse (stack) runs on the modulator-demodulator 172 in the equipment 500, and the other end runs on the interconnect function (IWF) in the storage facility 810.The reliable protocol link that equipment 500 and cellular radio network are 700 is supported the FTP link.One suitable reliable protocol is radio link protocol (RLP), such as in February, 1998 issue, title be in the IS-707.2 standard of " Data Service Options For Wideband Spread Spectrum Systems:Radio Link Protocol " definition and issue in March, 1999, defined in the IS-707-A.2 standard of title by " DataService Options For Spread Spectrum Systems:Radio Link Protocol ".In another was implemented, the transportation protocol link can for example, allow lost package to retransmit so that the different SDL carrying of reliability to be provided by passing through.

Attention: for the application (as: audio or video application) of the sequence of events of catching the data representation long-time continuous, what it is desirable to allow to wrap loses once in a while to avoid making memory element saturated.Also it is desirable to, change the loss of Signal Compression according to the quality of data link or reliability, because less compressed format is very effective to reducing packet loss.

In an example was implemented, data link obtained the support of the wireless channel under one of IS-75 standard or the CDMA-2000 standard (being positioned at the telecommunications industry association of the Arlington of VA).Perhaps, radio link can obtain the support of HDR (high data rate) channel, as shown in figure 19.Be that equipment just may comprise that equipment 500 is to provide a plurality of concurrent services (as: Speech Communication ability) on the different subchannels of same channel under the situation of cellular telephone channel of a number of support subchannel in data link.

The FTP link is further supported by the media such as the T1 line at

cellular radio network

700 and 810 of facilities of storage.Support that the physical layer of FTP stack can be PPP(Point-to-Point Protocol), Ethernet (CSMA/CD) or other physical layer protocol.Can run on above-mentioned any media (PSTN.ISDN etc.) at

storage facility

810 and 900 IP of PC (IP(Internet Protocol)) stack (or FTP as shown in figure 19 or SMTP (simple message transfer protocol (SMTP)) stack).If by semipermanent connection (for example: as being supported by cable modem or DSL modulator-demodulator), PC 900 connects storage facility 810 directly or indirectly, then equipment 500 may be set up the FTP link that always extends to PC 900.

In a related embodiment, available electron or optical data link replace wireless data link.In such enforcement, the control logic piece connects the standard telephone jack by wire line MODEM.(as: when sealing the user is in inner room in the building or screening-off position) just needs such ability in the time can not setting up the Radio Link with acceptable quality.
