Abstract
Prevent data card from missing plug-in system in drive recorder the invention discloses one kind,It is characterized in that,Increase a neck hatch before neck,The switch of a hard contact is provided with the neck hatch,Hard contact can be interrelated with the switch of neck hatch,Hard contact is equivalent to a touch-switch,One of contact is grounded,The other end of contact is connected to the I/O of drive recorder main control chip,So,The unlatching of small neck hatch and closure state before neck,Interrupted by I/O and pass to main control chip,When master control detects that small neck hatch is opened,Master control can actively stop the operation making video recording,Current dossier is complete and close the archives,The invention enables current archives and the significant data of file system it is reliable with it is complete,Simultaneously,Because sensed in advance pulls out the action of card,And the action of perfect closing archives is done,Any bosom gear or file system corruption will not also be caused by pulling out card even if execution.
Description
Technical field
Prevent data card from missing plug-in system in drive recorder the invention belongs to one kind.
Background technology
The good design of drive recorder power-supply system can handle what abnormity of power supply power down be able to may be brought to data card
Damage, but can not prevent from artificially mispluging caused damage when pulling out data card.
Among drive recorder product design, no matter SD card or TF card（MicroSD cards）Eject card will be used
Groove.It can be automatically locked at when card insertion is fashionable among neck, then firmly one push away neck meeting automatic unlocking, data can be ejected automatically
Come, facilitate user to take out.
The neck for necessarily requiring selection to have good quality among product design, so just ensures that data card can reliably connect
It is connected among master chip, even adverse circumstances, even the traffic abnormities such as severe crash occur, data card can also be kept can
It is abutted against phenomenon that is tactile, and being unlikely to cause the electrical connection of the generation essence between external memory and product to disconnect.
It should first pass through UI interfaces to stop current behavior of making video recording correctly to pull out card operation, do again pull out the dynamic of card afterwards
Make.
Even if using reliable Power Management Design, even if being used for high-quality neck；If user is not according to correct
Flow operates, then artificially extracts the data card in the state of making video recording.It is similar with abnormal power-down, it can equally produce following two
The exception of kind data card：
A) the very big probability of the current document recorded forms bad shelves due to lacking index data, subsequently can not positive frequentation
Ask；
B) critical data such as file allocation table and file linked list etc. on data card, it is also possible to lose or damage；So as to not have
There is method in this data cards of follow-up normal use, it is necessary to be formatted to this data cards or repaiied by special instrument
Multiple file allocation table and file linked list etc., can just recover normal use.
Among the use environment of reality, because scope is big, terminal client numerous types；It is difficult to require that final user is complete
The full operation for strictly according to operational procedure pull out card.A new design is needed just to ensure that any plug of client will not be led
Cause the data reliability problem of data card.
The content of the invention
The technical problems to be solved by the invention are to provide one kind prevents data card from missing plug-in system in drive recorder.
It is as follows that the present invention solves the technical scheme that above-mentioned technical problem is taken：
One kind prevents data card from missing plug-in system in drive recorder, it is characterised in that increases a card before neck
Groove hatch, is provided with the switch of a hard contact on the neck hatch, hard contact can and the switch of neck hatch mutually close
Connection, hard contact are equivalent to a touch-switch, and one of contact is grounded, and the other end of contact is connected to drive recorder
The I/O of main control chip, so, the unlatching of small neck hatch and closure state before neck, interrupted by I/O and pass to master control
Chip, when master control detects that small neck hatch is opened, master control can actively stop the operation making video recording, and current dossier is complete
And close the archives.
Preferably, the neck hatch for preventing that data card from missing plug-in system in drive recorder also includes：Move with the hand
The neck hatch of switch or the neck hatch of cover-lifting type.
Preferably, during the I/O of the main control chip for preventing data card from missing plug-in system in drive recorder has
Disconnected function.
After such scheme, so that current archives and the significant data of file system is reliable
With complete, simultaneously as sensed in advance pulls out the action of card, and has done the action of perfect closing archives, even if performing
Any bosom gear or file system corruption will not also be caused by pulling out card.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
Obtain it is clear that or being understood by implementing the present invention.The purpose of the present invention and other advantages can be by the explanations write
Specifically noted structure is realized and obtained in book, claims and accompanying drawing.
Brief description of the drawings
The present invention is described in detail below in conjunction with the accompanying drawings, to cause the above-mentioned advantage of the present invention definitely.Its
In,
Fig. 1 is that the present invention prevents data card from missing the structural representation of plug-in system in drive recorder；
Fig. 2 is that the present invention prevents data card from missing the circuit realiration schematic diagram of plug-in system in drive recorder.
Embodiment
Embodiments of the present invention are described in detail below with reference to drawings and Examples, and how the present invention is applied whereby
Technological means solves technical problem, and the implementation process for reaching technique effect can fully understand and implement according to this.Need to illustrate
As long as not forming conflict, each embodiment in the present invention and each feature in each embodiment can be combined with each other,
The technical scheme formed is within protection scope of the present invention.
One kind prevents data card from missing plug-in system in drive recorder, it is characterised in that increases by one before neck
Individual neck hatch, is provided with the switch of a hard contact on the neck hatch, hard contact can and neck hatch switch phase
Mutual correlation, hard contact are equivalent to a touch-switch, and one of contact is grounded, and the other end of contact is connected to driving note
The I/O of device main control chip is recorded, so, the unlatching of small neck hatch and closure state before neck, is interrupted and passed to by I/O
