Description
Technical Field
The utility model relates to a data storage field particularly, relates to an electronic hard disk for vehicle event data recorder.
Background
The existing automobile data recorder adopts an SD card or a TF card as a storage medium, the SD card and the TF are easy to damage in the long-term reading and writing process, once the SD card and the TF are damaged, the problem is that a video cannot be recorded continuously, meanwhile, the previously recorded video cannot be checked, and the recorder loses the function of recording the video by the initial design.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a be applied to vehicle event data recorder's electronic hard disk, its storage capacity is big, stability is high, read-write speed is fast.
The utility model provides an electronic hard disk for vehicle event data recorder, includes vehicle event data recorder, be equipped with the main control unit in the vehicle event data recorder, the electronic hard disk is including the communication unit that is used for connecting vehicle event data recorder and the memory cell that is used for saving video signal, the communication unit is connected with the memory cell, the memory cell is connected by the communication unit the main control unit to carry out data exchange with vehicle event data recorder.
Furthermore, the communication unit comprises an SDIO communication chip and is connected with the automobile data recorder through an SDIO interface.
Further, the storage unit is a NAND Flash memory or an EMMC chip.
Further, the main control unit is a recorder CPU.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the electronic hard disk adopts a large-capacity NAND Flash memory or EMMC chip as a storage unit to replace an SD card or a TF card, has the characteristics of high stability, high read-write speed and the like, and avoids the problem that the existing automobile data recorder is easy to damage due to repeated read-write by adopting the SD card or the TF card as a storage medium.
2. The original SDIO interface communication protocol of the automobile data recorder is adopted, the automobile data recorder and the electronic hard disk are connected in a mode that an SDIO communication chip circuit is used as a bridge, and the purpose that a control chip of the automobile data recorder reads and writes a large-capacity NAND Flash memory or EMMC chip is achieved on the basis that a software system framework is not changed.
Drawings
Fig. 1 is the utility model discloses a be applied to vehicle event data recorder's electronic hard disk's functional block diagram.
Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1, in a preferred embodiment, the electronic hard disk applied to the driving recorder of the present invention mainly includes a driving recorder 1 and an electronic hard disk 2. The automobile data recorder 1 is internally provided with a main control unit 10, and in this embodiment, the main control unit 10 is a recorder CPU.
The electronic hard disk 2 comprises a communication unit 20 and a storage unit 21, the communication unit 20 is connected with the storage unit 21, the communication unit 20 is used for connecting the automobile data recorder 1 to realize data exchange between the main control unit 10 and the storage unit 21, and the storage unit 21 is mainly used for storing video signals.
In this embodiment, the storage unit 21 uses a large-capacity NAND Flash memory or an EMMC chip, and the communication unit 20 uses a corresponding NAND Flash or EMMC interface protocol to exchange data with the storage unit 21. The high-capacity NAND Flash memory or EMMC chip is used as a storage unit to replace an SD card or a TF card, so that the automobile data recorder has the characteristics of high stability, high read-write speed and the like, and the problem that the existing automobile data recorder is easy to damage due to repeated read-write by using the SD card or the TF card as a storage medium is solved.
In this embodiment, the communication unit 20 includes an SDIO communication chip, and the communication unit 20 is connected to the drive recorder 1 through an SDIO interface. It should be noted that the existing car recorder and the TF card or the SD card mainly communicate with each other through an SDIO interface protocol, and in this embodiment, an SDIO communication chip is used to connect the storage unit 21 and the main control unit 10, so that a control chip of the car recorder can read and write a large-capacity NAND Flash memory or an EMMC chip without changing a software system frame, thereby ensuring software compatibility and system stability.
It should be noted that the SDIO communication chip, the NAND Flash memory, and the EMMC chip may be commercially available chips, which are not described herein.
While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and scope of the appended claims.
