Power supply terminal 6 is being connected with control device 5 in being arranged on enclosure body 10.Control device 5 is connected with video camera 2, acceleration transducer 3, card connector 32, display part 17 and action button 18 through not shown interface, and power supply terminal 6 can be supplied power to video camera 2, acceleration transducer 3, card connector 32, display part 17 and action button 18 through control device 5.

And control device 5 is for example shown in figure 11, is provided with: CPU (CentralProcessing Unit) 51; The RAM (RandomAccess Memory) 52 of memory block is provided to above-mentioned CPU51; Interface 54, this interface 54 is connected with video camera 2, acceleration transducer 3, display part 17 and action button 18; ROM (Read Only Memory) 55, this ROM55 stores CPU51 carries out application program that required processing implements or operating system etc. for the function of controlling video camera 2, acceleration transducer 3 and memory storage 4 performance drive recorder D program; With the bus 53 that is connected CPU51, RAM52, ROM55, interface 54 and card connector 32.And memory storage 4 is provided with card connector 32 and SD storage card 33, and storing mechanism is made up of control device 5 and memory storage 4.

Then; Acceleration transducer 3 is basically so long as can detect 2 acceleration all around just passable of housing 1; In the occasion that will obtain more to add velocity information, also can use 3 acceleration transducer of the acceleration of the above-below direction that can detect housing 1.And acceleration transducer 3 specifically, for example can adopt piezoelectric type, semiconductor piezoelectricity (ピ ア ゾ) resistance-type, electrostatic capacity type, other various acceleration transducers.

And; Acceleration transducer 3 is by the sample period of regulation; For example 2 the acceleration all around of the cycle detection housing 1 of 10ms (microsecond) is exported the acceleration signal as analog voltage signal, converts this acceleration signal to digital signal input control device 5.

On the other hand, video camera 2 continues photography at this camera coverage always, becomes the image transitions of being taken the photograph electric signal to control device 5 outputs.Image has been done the explanation of broad sense, and image also comprises animation except rest image.

Shown in an example of the flow chart of Figure 12; Video camera 2 continues to photograph, acceleration transducer 3 continues sense acceleration (step S1); When control device 5 obtains from the acceleration information of the image information of video camera 2 and acceleration transducer 3 detections; The acceleration information in the moment of obtaining this image information, date and time are marked Seki relatedly connect a pair け) at this image information (step S2); In case it is stored in RAM52 or the SD storage card 33, has accumulated the image information of predefined photography time amount; Then all images information of accomplishing related mark and in above-mentioned photography time, obtain is summed up and generated a file (step S3, S4) together, it is stored in (step S5) in the SD storage card 33 by card connector 32.After this, after the image information of having accumulated the photography time amount, generate new file according to identical order.Like this, control device 5 is spanned file in order, and is stored in the SD storage card 33, and after being filled with above-mentioned file in the SD storage card 33, new file is deleted and stored to the ancient deed outside the file of forbidding covering in order.

Said operation in the accessory power supply connection of cart and when power supply terminal 6 drops into electric power, till the acceleration that accessory power supply cuts out or acceleration transducer 3 detects surpasses threshold value, is proceeded times without number.

And; In detail; Follow at the micro universal universal serial bus socket 24 of register side electric wire C1 and to be connected with vehicle power supply and the micro universal serial bus connector 25 of the mains side electric wire C2 of input voltage signal connects in ID pin 25d occasion; When accessory power supply was connected, control device 5 detected an input with voltage signal in the pin of the power supply terminal 6 that is connected with the ID pin 25d of micro universal serial bus connector 25 through register side electric wire C1, began to photograph and with acceleration transducer 3 sense acceleration with video camera 2; Spanned file also stores in the SD storage card 33, and each one is played a role as drive recorder D.

To this; The occasion that connects with the micro universal serial bus connector of the USB lines that are connected with not shown external units such as microcomputer at the micro universal universal serial bus socket of register side electric wire C1 24; Because do not have input voltage signal on the ID pin of the micro universal serial bus connector of external apparatus; So, even on power supply terminal 6, exist electric power to supply with, owing on of the pin of the power supply terminal 6 that is connected with the ID pin 24d of micro universal universal serial bus socket 24, there is not the input of voltage signal; So; Control device 5 does not make any work in video camera 2, the acceleration transducer 3, and the external memory that makes SD storage card 33 be used as PC carries out work, thereby can the external apparatus side be operated by the file in the SD storage card 33.

Promptly; Drive recorder D according to this embodiment; Can judge drive recorder D self to carry on vehicle and be in the state that needs photography and acceleration detection; Still is connected with external unit such as PC and is in and need not photograph and the state of acceleration detection, corresponding behaviour in service is moved.

Therefore, can not upgraded such state of affairs by new file, when carrying on vehicle, can begin photography automatically, and can avoid photography to pass out of mind because of be connected the file that causes beginning photographing, comprise important images information with external unit.

Like this, drive recorder D self and behaviour in service are moved adaptably, thereby the user need not specially through manual operation the action of drive recorder D to be selected or controlled, and has the advantage that alleviates user's burden.

In addition, generate the photography time of a file, the user can be by need the selecting in the photography time span of certain degree of user, for example, can set for the photography time of a file be appointed as 15 fens, 30 minutes, 60 minutes, 120 minutes.Promptly; For example; In the occasion of setting photography time for 15 minutes; Control device 5 is being accumulated 15 timesharing to the image information of video camera 2 photographies, sums up the image information of attaching the photography time amount that acceleration information, time on date etc. are arranged explicitly and generates a single file together, and store in the SD storage card 33.

Owing to can so change the photography time that generates a file, therefore, can specify and the running time corresponding photographic time, can obtain the required image information of user.And, owing to can specify and the running time corresponding photographic time, so the user can obtain accommodating the file of the image information that does not have seam midway.

In addition, shown in an example of the process flow diagram of Figure 13, control device 5, two the acceleration all around of the cart of acceleration transducer 3 outputs with correspond respectively to this each acceleration preset threshold in advance and compare (step S6); Surpass above-mentioned threshold value as condition with the side in the acceleration all around of acceleration transducer 3 detections; When condition is reached; From the moment that condition is reached; Be to begin to continue the stipulated time under this occasion, for example continued for 10 seconds and photograph and acceleration detection (step S8) from the moment of above-mentioned acceleration above threshold value; No matter the photography time of setting how, file is generated (step S9); The file storage (step S10) in SD storage card 33 that generates, the processing (step S11) of forbidding covering this document simultaneously; Above photography, acceleration detection and file generate the power supply (step S12) that whole processing among such drive recorder D are over and close drive recorder D.Control device 5 shows not fluctuating acceleration, judges that in step S6 acceleration surpasses the occasion of threshold value, implements processing thereafter as relay process.And, having been implemented to forbid covering the file of processing, can not upgrade automatically because of the use of thereafter drive recorder D, forbid that the processing that covers, drive recorder D self are the files that can it be replaced into other only if remove through manual operation.Specifically; For example; When SD storage card 33 writes new file, in SD storage card 33, do not use off-capacity when being used for storing this new file, as long as confirm file attribute; The file that deletion is not forbidden covering, be the file of old rise time, store above-mentioned new file and get final product.

Therefore;, cart has an accident in going and when detecting the acceleration above threshold value; Exist produced before the accident by the occasion of the image information before the documentation; The image information that control device 5 obtains photography in the 10 second time after the accident from the accident adds together with said image information by before the documentation of being produced before the accident, with they as a blanket file storage in SD storage card 33.Therefore; Be retained in the image information of production in long-time after the accident before from the accident in the memory storage 4 as a file; Can confirm a part of reason of accident, not only be easy to confirm culprit, and can not lose the important images information that to confirm culprit.

In addition; Be included in the above-mentioned file of image information that acceleration surpasses the moment production of threshold value owing to forbid covering, therefore, when restarting after the accident to photograph etc.; Above-mentioned file can not be capped and lose, and can reliably stop the loss of the important image information that is used for confirming culprit.

And then because the image information in storing mechanism, also having stored when taking place except that accident, therefore, the user can be with reference to accident image information in addition, can be used to improve the peripheral scenery of road that oneself driving technology or appreciation were gone.

And; After the photography of stipulated time after accident takes place; The power supply of drive recorder D is cut off; Can not photograph, acceleration detection, file generate and all processing such as file storage, therefore, can in storing mechanism, reliably keep the file of the image information of a part of reason that comprises the accident of having produced.

And; In the drive recorder D of this embodiment; The judgement that whether surpasses threshold value for acceleration in the control device 5 is; Surpass the occasion of threshold value at acceleration transducer 3 with the continuous stipulated number of the acceleration ground of the sample period sampling of regulation, be used as acceleration above threshold value and spanned file with file storage in memory storage 4.Promptly; Acceleration accumulative total stipulated number and surpass threshold value in set time of obtaining in the sample period as condition; To comprise the file that carries out the image information after the stipulated time photography from the moment that this condition is reached and generate, and with file storage in memory storage 4.Like this, the condition that file generates when not only being used as accident to acceleration above threshold value also can be the acceleration condition that file generates when the set time surpasses threshold value as accident.In addition; The said fixing time is not that expression is unalterable, immutable, and only be for reach as condition after stipulated time of photography time distinguish and be called " set time " easily; As after state, setting change that can be through the user.

Once also be used as condition if surpass threshold value to acceleration merely; During the interference in detecting noise or going causes suddenly big acceleration; Will judge by accident and be decided to be accident; But, such surpass the occasion of threshold value to acceleration in the set time above-mentioned as condition, have the false judgment that can eliminate noise or interference and cause, the advantage of ability high Precision Detection accident.

And, have the upper limit on the balance of sample period and set time, and afore mentioned rules number of times and threshold value can be set by the user.Like this; Condition of road surface, pavement behavior, the pattern that the vehicle of drive recorder D is set, the custom of going that after this user can corresponding go; Stipulated number and threshold value are changed; Therefore, can by control device 5 be provided with the pattern of the vehicle of drive recorder D, the custom of going, travel situation, pavement behavior and correspondingly judge.

And then; The drive recorder D of this embodiment; As above-mentioned, housing 1 when handle H etc. installs, through the operation of user to action button 18; The attitude that acceleration transducer 3 in stopping by Straddle riding type vehicle is installed towards vehicle is by the initial value of acceleration transducer 3 sense acceleration; And it is stored in the control device 5 as offsetting (オ Off セ Star ト) acceleration, remove in the acceleration that detects by acceleration transducer 3 hereafter and offset acceleration, the influence that exists with ... the gravity in sense acceleration attitude, that be included in acceleration transducer 3 that acceleration transducer 3 installs towards vehicle is got rid of.

Therefore, the drive recorder of this embodiment can not exist with ... the installation attitude of acceleration transducer 3, and precision detects the acceleration that exists with ... the vehicle that going of vehicle produced well, generation that can precision detection accident well.

In addition; Even owing to when the detection axle of acceleration transducer 3 is two, does not correctly install, when the detection axle of acceleration transducer 3 is three, correctly do not install towards the above-below direction all around of vehicle towards the direction all around of vehicle; Also can correctly detect the acceleration of all directions of vehicle; Therefore, being easy to a drive recorder D is arranged on the vehicle.

And then; In this drive recorder D, in housing 1, be provided with auxiliary power 35, shown in an example of the process flow diagram of Figure 13; In driving, supply with (step S7) when interrupting from the electric power of vehicle power supply; Even acceleration surpasses threshold value, control device 5 is also accepted electric power from auxiliary power 35 and is supplied with, identical action when photography, acceleration detection (step S8) and the file that carried out for 10 times in second generates (step S9) and store (step S10) etc. to SD storage card 33 and take place with accident.Promptly; In the drive recorder D of this embodiment; Acceleration transducer 3 detected acceleration surpass threshold value or acceleration surpasses threshold value in the set time satisfying; And supply with any situation of interrupting wherein as condition, when condition is reached, in the stipulated time in the moment of reaching from condition from the electric power of vehicle power supply; Be during 10 seconds, to continue to photograph and acceleration detection under this occasion; Though the photography time that sets how all spanned file and the file storage that generates in SD storage card 33, forbid covering the processing (step S10, S11) of this document simultaneously, the power supply (step S12) that the whole backs of finishing dealing with among the drive recorder D such as above photography, acceleration detection and file generation are cut off drive recorder D.

In detail; Even acceleration does not surpass threshold value; When cart comes in contact with something or overturning and causing is connected with vehicle power supply register side electric wire C1 or mains side electric wire C2 broken string or accessory power supply are closed, supply with from the electric power of vehicle power supply and to be cut off, therefore; Exist from produce before the state of affairs takes place, by the occasion of the image information before the documentation; Control device 5, during 10 seconds thereafter that beginning takes place from this state of affairs in the image information of production, add this from produce before the state of affairs takes place, by documentation image information before; With they as a total file storage in SD storage card 33, with the power-off of drive recorder D.

Therefore; Not only according to the acceleration detection accident; And; Causing electric power to supply with even certain abnormal conditions take place vehicle interrupts such state of affairs, also can be retained in the image information of production before and after this state of affairs takes place in the memory storage 4 as a file, can confirm a part of cause of this state of affairs.

And; Even supply with the occasion of interrupting at electric power; Also file is generated and stored, so, even in the occasion that can not carry out based on the accident detection of acceleration; Also improved the possibility that can detect, the image information when generation that can high precision understanding accident, storage accident to the overturning or the contact accident of cart.

In addition, because coverings that be under an embargo of above-mentioned file, so, supply with when electric power when recovering, recovering to photograph etc., can not occur being capped and make the situation of information loss, can be really the loss of the image information that might take place for accident be stoped.

And then; After the photography of the stipulated time of in electric power is supplied with, having no progeny; The power supply of drive recorder D is closed; All processing such as photography, acceleration detection, file generation and file storage are not all implemented, and therefore, the file that includes the image information of accident possibility occurrence can reliably be retained in the storing mechanism.

Auxiliary power 35 has been accumulated video camera 2 and has been carried out above photography in 10 seconds, acceleration detection and file generation and store needed electric power to SD storage card 33.So can be retained in the file of the image that comprises a part of cause that to confirm accident of production before and after accident reliably in the memory storage 4.

And then; In driving, supply with when interrupting, file is generated and stored in the SD storage card 33, therefore from the electric power of vehicle power supply; Even from once after the storage of SD storage card 33 ends, supply with the quantity of information of the image information of producing till interrupting to electric power less; Photography time does not have under the occasion of spanned file less than the photography time of as above-mentioned, setting, and when the user is stopped Straddle riding type vehicle and when closing accessory power supply, supplies with from the electric power of the vehicle power supply in driving to be interrupted; Thereby; Control device 5 with describe likewise before, accept to supply with from the electric power of auxiliary power 35, carry out photography in 10 seconds, acceleration detection and spanned file and action such as store to SD storage card 33.Therefore, even in the not enough occasion of file size, the user just need not operate and can file be generated and stored in the memory storage 4 going at the end, the preservation that conveniently can not omit the image of being produced.

In addition; Can sign in to the threshold value of drive recorder D with respect to each acceleration of two; Have two respectively, one is the threshold value that is used for the generation of detection accident, the photography that stops video camera 2, spanned file and stores to SD storage card 33, although and another is lower than this threshold value; But can set the desirable value arbitrarily of user for as the acceleration of the unlikely degree of causing accident threshold value by way of caution.

Surpass the occasion of this warning threshold at the acceleration of correspondence, control device 5 makes loudspeaker 20 sound that gives a warning, and informs to the user of steering vehicle to have detected dangerous acceleration.Therefore, among the drive recorder D in this embodiment, when surpassing warning threshold; Make loudspeaker 20 that warning take place; Therefore, the user hears that warning will discover the situation that the driving variable of self gets roughly or speed becomes too fast, can preventing trouble before it happens accident.

Owing to judging acceleration whether during above this warning threshold, carry out above-mentioned judgement after as above-mentioned, getting rid of the influence of gravity of the installation attitude that exists with ... housing 1, therefore, can irrespectively accurately the user be given a warning with the installation attitude of housing 1.

And; As above-mentioned; Drive recorder D according to this embodiment; In housing 1, accommodated all hardware such as the needed video camera of the function that is used for bringing into play drive recorder D 2, acceleration transducer 3, memory storage 4 and control device 5, can make being provided with of vehicle carried out easily, can improve lift-launch property to vehicle.
