More than, sketched the present invention.Further, through come following explanation embodiments of the invention with reference to accompanying drawing, the details of invention will be more obvious.
Description of drawings
Through describe preferred illustrative embodiment of the present invention in detail with reference to accompanying drawing, above purpose of the present invention and advantage will become more obvious, wherein:
Fig. 1 be illustrate according to the operation of the Tachographs of the embodiment of the invention outline flowchart.
Fig. 2 illustrates the synoptic diagram that storage area is distributed in the instance on a plurality of storage mediums.
Fig. 3 is the block diagram that illustrates the Hardware configuration instance of Tachographs.
Embodiment
To the specific embodiment about the vehicle according to the invention information-recording apparatus be described with reference to accompanying drawing.
In the present embodiment, suppose said invention is applied to the Tachographs 100 that for example has structure shown in Figure 3.Yet the present invention is not limited to Tachographs, but can for example be applied in the car that digital revmeter or similar has the identical data writing function on the recording unit.
In view of the above, microprocessor 11 can be visited a plurality of storage cards 21 and 22 that are installed in the storage card reader 12 one by one, and can carry out reading and writing data.
Output was called the electric signal of velocity pulse when speed pickup 32 reached the reservation amount in the transmission output shaft rotation of vehicle.Speed pulse signal by speed pickup 32 outputs is imported in the microprocessor 11 through interface 15.Through the generation state of monitoring velocity pulse, can grasp the translational speed (speed of a motor vehicle) or the amount of movement of vehicle.
Under the situation of the Tachographs of reality, can increase the number of components that is connected to main body 10 in the car and collect various information.For example, camera can connect and is main body 10 in the car in a plurality of cars, so that take outer scene with one, and with another shooting vehicle interior situation.Further, can GPS (GPS) receiver be connected in the interior main body 10 of car to obtain the positional information about vehicle.Further, can obtain the various information of vehicles that show transport condition, for example, about the information of the ON/OFF state of engine speed, brake, the gear of variator etc.
Yet, for example, because it is big to take the view data capacity that obtains through camera in the car 31, thus if trigger is repeated to start, needs are write down a large amount of view data, thereby, the storage area of labor in order to store a large amount of view data.Further, with respect to by the information that conventional recording operation obtained, less relatively by the quantity of information that instance obtains.Yet, As time goes on and the record great deal of information, therefore, storage area that will labor.
On the other hand, about storing the Nonvolatile memory card of recorded data, the capacity that each storage card can write down all is limited.Therefore, if trigger repeated priming or recording operation continue in long-time, the clear area of storage card can disappear, and therefore, with the recording operation that can not allow subsequently, perhaps can delete old significant data.
For example, under the situation of taxi company or traffic company, need to be grasped the actual travel state that each drives the driver of commercial vehicle, carry out safety traffic with driver instructor.In order to grasp this transport condition, can use by institute's information recorded such as Tachographs.Yet under the situation of the in-vehicle device that is installed in the for example Tachographs on the commercial vehicle, owing to continuous recording bulk information every day, the capacity of the storage card of storage data is easy to exhaust.
For example, when routine work finishes, under the situation that each driver pulls up the storage card of in-vehicle device and give back, can data be transferred to the management computer of installing in the office of company from storage card.In this case, when routine work finishes,, can on storage card, create new clear area through from the storage card deleted data.Yet data were transferred to the management computer from storage card before, storage card possibly be in the state of off-capacity.If the state of off-capacity takes place, can not write down significant data again, perhaps may delete the important information of noting.
Therefore, in Tachographs shown in Figure 3 100, a plurality of draw-in groove 12a and 12b offer storage card reader 12, make two or more individual memory cards 21 and 22 can be installed in the main body 10 in car.Further, main body 10 inner microprocessors 11 have the function of using a plurality of individual memory cards 21 and 22 of installing to guarantee record destination desired zone in the car.
Below, the concrete operations about data recording of Tachographs 100 will be described.The summary of the characteristic manipulation of Tachographs 100 shown in Figure 3 is shown in Fig. 1.Operation shown in Fig. 1 realizes through the processing of microprocessor 11.In addition, Fig. 2 shows a plurality of storage cards 21 and 22 is carried out the example that posting field distributes.
In the S11 step, microprocessor 11 reads the state of storage card reader 12 and discerns whether a plurality of storage card 21 and 22 is installed on draw-in groove 12a and the 12b.Under the situation that a plurality of storage cards 21 and 22 are installed, process proceeds to step S12, and under the situation of having only a storage card to install, process proceeds to step S15.
In step 12, microprocessor 11 carries out the distribution of master record media and secondary recording medium for a plurality of storage cards 21 and 22 that are installed on the storage card reader 12, the distribution of the stepping row major level of going forward side by side.
That is, one in a plurality of storage cards 21 and 22 will be assigned as the master record media, and wherein another will be assigned as secondary recording medium.In order to select in a plurality of storage cards 21 and 22 which will be the master record media, and for example, draw-in groove 12a that storage card is installed and the position of 12b can be used for identification, and the value like the information of card ID etc. that perhaps writes in advance on storage card 21 and 22 can be used for discerning.About the distribution of priority, for example, the priority of master record media is high, and the priority of secondary recording medium is low.
In step S13, but microprocessor 11 is respectively the kind that a plurality of storage cards 21 and 22 distribute recorded information.
In the present embodiment, microprocessor 11 will be divided into two set types and handle as the data of record object.One group corresponding to according to the triggering that when detecting unusual big acceleration, produces and irregular data recorded, another group then corresponding to the constant time interval often and the data of periodic logging.
In the instance of Fig. 2,, can and can both guarantee for the zone of the data allocations of trigger recording group for the zone of the data allocations of periodicity record group about the master record media.In addition, about secondary recording medium, can only guarantee zone for the data allocations of periodicity record group.That is, distribute and make that periodically the data of record group can be recorded on master record media and the secondary recording medium, and the data of trigger recording group are merely able to be stored on the master record media.
In step S14, microprocessor 11 is the maximal value of every kind of information type assignment record capacity or the capacity ratio that distributes master record media and secondary recording medium.
For example; In example shown in Figure 2; Among the whole zone on the master record media (its capacity is C1max), can distribute to the max cap. of the data of trigger recording group in this zone and confirm as Ca, confirm as Cb and can distribute to periodically the max cap. of the data of record group in the zone.In addition, the whole zone on the secondary recording medium (its capacity is C2max) confirmed as this zone and can be distributed to the periodically max cap. of the data of record group.Max cap. can be formulated and make the ratio of Ca and Cb remain unchanged.
In step S15, whether microprocessor 11 identifications produce the recording instruction to recording medium.That is, think that recording instruction produces when the data that obtain along with triggering for generating are in state to be stored, perhaps produce when place's data are in state to be stored that then, process proceeds to step S16 in the regular moment of conventional recording operation.
No matter the generation of recording instruction through obtaining the for example new data of image constantly, and deposits the data that this obtains in the impact damper of volatile memory 17 for example in, when producing when triggering, still can be on storage card 21 and 22 with the data storage that obtains in the past.
In step S16, the state in the zone on the above-mentioned master record media of microprocessor 11 inspections, whether identification then exists enough clear areas to preserve the data as the record object.For example, under state shown in Figure 2, when generating recording instruction along with triggering for generating, can whether enough among the max cap. Ca in the said zone of microprocessor 11 identification for the size of the clear area of the data allocations of trigger recording group.
Having a storage card 21 to be installed under the situation in the storage card reader 12, storage card 21 is considered to the master record media, and can assert that secondary recording medium does not exist or its capacity is 0.
In step S17, microprocessor 11 is about the zone of the record object data that the has been endowed recording instruction assignment record destination, clear area from the master record media.
In step S18, whether the record object data that microprocessor 11 identifications have been endowed recording instruction is the information that can be stored on the secondary recording medium.That is, in instance shown in Figure 2, can be the zone of the data allocations of periodicity record group because in secondary recording medium, only exist, microprocessor 11 identifications can be write down the periodically data of record group, and can not write down the data of trigger recording group.
In step S19, the state in the zone on the secondary recording medium of microprocessor 11 inspections, and whether identification exists enough clear areas to come the keeping records object data.For example, under the state shown in Fig. 2, when produced recording instruction conventional writing time down, whether microprocessor 11 is discerned among the max cap. C2max in said zone can enough for the size of the clear area of the data allocations of periodicity record group.
In step S20, microprocessor 11 comes the zone of assignment record destination from the clear area on the secondary recording medium about the record object data that has been endowed recording instruction.。
In step S21, in order to guarantee new zone, microprocessor 11 is searched for the recorded information of legacy data on master record media or secondary recording medium, and the data that arrive of Delete Search automatically.Further, microprocessor 11 distributes the new clear area of guaranteeing through deletion to be used as writing down the zone, record destination of object data.
In step S22, microprocessor 11 will be through S17, and the record object data in the zone, storage purpose ground that operation distributed of S20 and S21 is written on master record media or the secondary recording medium.
Think that a plurality of storage cards 21 and 22 in fact cut apart according to for example following mode.That is, a storage card 22 distributing to secondary recording medium is installed in the car on the main body 10 for a long time, another storage card 21 of distributing to the master record media then in the car main body 10 separate and after routine work, take back by the driver.Then, data recorded on the storage card 21 is transferred in the management computer in the office, and deleted the data that shift from storage card 21.Further, the driver is installed in storage card 21 in the car in the main body 10 when second day work begins once more.About distributing to the storage card 22 from recording medium, the corporate manager can be in needs, for example because the generation of traffic hazard and storage card 22 main body 10 in the car is separated, and obtain and are recorded in data on the storage card 22.
Under any circumstance, a plurality of individual memory cards 21 and 22 can be used simultaneously, therefore the data that surpass single storage card memory limitations can be write down and preserve.That is, can in very long a period of time, write down the mass data of image for example or often and the data of periodic logging continuously.Therefore, even in every day record business practice about the various information of vehicle operating, the also state of rare off-capacity.
Further, because the deletion legacy data automatically guarantees new zone under the situation of off-capacity, so the situation that the data that can avoid newly obtaining can't write down.Further,, perhaps want the data recorded kind to come the management accounts destination, can use a plurality of storage cards 21 and 22 rightly through dividing through being that a plurality of storage cards 21 and 22 distribute priority.That is,, make when the work of every day begins and finishes, dismantle and install only card by the driver even under the situation of using a plurality of storage cards 21 and 22, also can manage.
In the above-described embodiments, suppose that two storage cards 21 and 22 are installed in the car in the main body 10, but three or multi-memory card more also can be installed.Use three or more under the situation of multi-memory card at the same time, for example, can distribute a recording medium, and can to distribute the residue recording medium be secondary recording medium as the master record media.
As stated, can be applied to according to information-recording apparatus of the present invention and to obtain automatically and the equipment of store car information, as be installed on the vehicle Tachographs or digital revmeter as in-vehicle device.Especially, even be installed under the situation of the in-vehicle device on the commercial vehicle, also can suppress off-capacity and in very long a period of time, continue to carry out recording operation.
Although illustrated and explained the present invention, it will be apparent to one skilled in the art that and to carry out variations and modifications based on instruction of the present invention for special preferred embodiment.Within spirit of the present invention, scope and intention that accompanying claims limited, this variation and modification are conspicuous.
