Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a mechanical hard disk shockproof device, comprising: a first acceleration sensor, a second acceleration sensor and a control unit;
the first acceleration sensor is arranged on the hard disk damping box;
the second acceleration sensor is arranged on the equipment mainboard;
the control unit is respectively connected with the first acceleration sensor and the second acceleration sensor and used for determining whether to close the mechanical hard disk according to the numerical values acquired by the first acceleration sensor and the second acceleration sensor.
Specifically, a vehicle-mounted video recorder using a mechanical hard disk as a memory is taken as an example to explain the mechanical hard disk shock-proof device provided by the present invention, fig. 1 is a schematic structural diagram of the vehicle-mounted video recorder provided by the present invention, as shown in fig. 1, an equipment main board 105 and a hard disk shock-proof box 104 are arranged inside the vehicle-mounted video recorder, and the equipment main board 105 and the hard disk shock-proof box 104 are in communication connection. The hard disk damping box 104 is internally provided with a damping mechanism and a mechanical hard disk 106, and the damping mechanism provides a damping function for the mechanical hard disk 106.
The invention provides a mechanical hard disk shockproof device, comprising: a first acceleration sensor 101, a second acceleration sensor 102 and a control unit 103. The first acceleration sensor 101 is disposed on the hard disk shock-absorbing box 104, and the second acceleration sensor 102 is disposed on the device motherboard 105. The control unit 103 is connected to the first acceleration sensor 101 and the second acceleration sensor 102, respectively.
Since the device main board 105 and the hard disk damper 104 are connected by a signal line, there is no mechanical connection relationship. The first acceleration sensor 101 is disposed on a hard disk bracket of a hard disk damping box, and measures vibration data softened by a damping mechanism. And the second acceleration sensor 102 is arranged on the equipment main board 105, and directly detects the vibration data of the vehicle-mounted video recorder.
Compared with the vibration data acquired by the second acceleration sensor 102, the vibration data acquired by the first acceleration sensor 101 has lower vibration amplitude and frequency, a certain phase difference exists, and the acquired vibration data has a certain delay.
Based on the above characteristics, the control unit 103 determines whether the vibration impact borne by the mechanical hard disk 106 affects the mechanical hard disk according to the vibration data collected by the first acceleration sensor 101 and the second acceleration sensor 102. If it is determined that an impact is generated, the mechanical hard disk 106 is turned off so that no read/write operations are performed in a vibration region (a region where a vibration impact may cause damage to the mechanical hard disk).
Since there is a correlation between the difference in the vibration amplitude of the vibration data collected by the first acceleration sensor 101 and the second acceleration sensor 102 and the difference in the vibration time, the internal structure of the vehicle-mounted video recorder, and the shock absorbing mechanism mounted thereon, it is determined that the data used for closing the mechanical hard disk needs to be set according to the actual situation, which is not limited in this embodiment.
It should be noted that the present invention is described as a specific example of the vehicle-mounted video recorder, and besides, the mechanical hard disk shock-proof device provided by the present invention can also be used in other systems that need to use a mechanical hard disk. Secondly, the specific mechanism used by the damping mechanism in the hard disk damping box can be selected according to actual requirements, which is not limited in this embodiment.
According to the mechanical hard disk anti-vibration device provided by the invention, the time difference and the vibration amplitude difference of vibration are detected by the two acceleration sensors, and the mechanical hard disk can be closed before harmful vibration (the vibration exceeds a safe working condition threshold) is transmitted to the mechanical hard disk, so that the mechanical hard disk does not perform read-write operation in a vibration area, and the mechanical hard disk is prevented from being broken down due to overlarge vibration.
Optionally, the mechanical hard disk shock-proof device further includes: a storage unit;
the storage unit is connected with the mechanical hard disk through the control unit;
the control unit is also used for selecting a storage mode of the data information.
Specifically, the mechanical hard disk shock mounting still includes: and a memory unit. The storage unit is connected with the mechanical hard disk through the control unit, and the control unit is also used for selecting a storage mode of the data information.
A vehicle-mounted video recorder using a mechanical hard disk as a memory is taken as an example to explain the shock-proof device of the mechanical hard disk provided by the invention, fig. 2 is a schematic flow chart of a data storage control method provided by the invention, and as shown in fig. 2, the vehicle-mounted video recorder is provided with a multi-channel audio and video encoder for processing collected video and audio.
The control unit receives vibration data acquired by the first acceleration sensor and the second acceleration sensor, determines the real-time working condition of the current mechanical hard disk, and judges the storage mode of data information according to the real-time working condition.
When the control unit determines that harmful vibration does not exist, the control unit-cache control logic controls the storage unit to cache the processed video and audio data information, and the control unit-unloading control logic controls the mechanical hard disk to unload the video and audio data information from the storage unit into the mechanical hard disk according to a first-in first-out principle, so that unloading circulation of the data information is realized.
When the control unit determines that harmful vibration exists, the control unit-cache control logic controls the storage unit to cache the processed video and audio data information, and the control unit-unloading control logic controls the mechanical hard disk to stop unloading operation immediately and close the mechanical hard disk, so that a magnetic head of the hard disk is reset, and the recording surface of the magnetic disk is prevented from being damaged due to vibration.
In the mechanical hard disk shock-proof device provided by the invention, the storage unit is not sensitive to shock, and can be a solid state disk or a storage chip such as an SD, TF, MMC, eMMC and the like. The specific type and capacity of the storage unit can be selected according to actual requirements, which is not limited in this embodiment.

The mechanical hard disk shockproof device provided by the invention can cache data information into the storage unit and then transfer the data information into the mechanical hard disk in the data storage process by arranging the storage unit insensitive to the shock, can ensure that the data information is not lost on the premise of avoiding the mechanical hard disk failure caused by overlarge shock when the mechanical hard disk is closed by harmful shock, and can recover the data recording function of the mechanical hard disk when the shock is gentle or static to continuously transfer the data information from the storage unit.

and step S3, if the first vibration difference value is larger than a first preset vibration threshold value, closing the mechanical hard disk.
Specifically, in step S1, a first acceleration value and a second acceleration value are acquired from the first acceleration sensor and the second acceleration sensor, respectively.
In step S2, the first acceleration value and the second acceleration value obtained in step S1 are processed to determine a first vibration difference value, using the characteristics that the vibration amplitude and frequency of the vibration data collected by the first acceleration sensor are lower than those of the vibration data collected by the second acceleration sensor, and the vibrations have a certain phase difference.
It should be noted that, because there is a correlation between the difference in the vibration amplitude of the vibration data acquired by the first acceleration sensor and the second acceleration sensor and the difference in the vibration time, the internal structure of the vehicle-mounted video recorder, and the shock absorbing mechanism mounted on the vehicle-mounted video recorder, the size and the calculation mode for determining the first vibration difference value used for closing the mechanical hard disk need to be set according to the actual situation, which is not limited in this embodiment.

Specifically, in the vehicle running process, if the current mechanical hard disk is in a closed state, a first acceleration value and a second acceleration value are collected in real time, and a second vibration difference value is determined according to the first acceleration value and the second acceleration value.
If the second vibration difference value is smaller than the second preset vibration threshold value, it is indicated that the vibration does not affect the mechanical hard disk at the moment, and the mechanical hard disk is started to perform normal read-write operation.
It should be noted that, in the method for preventing vibration of a mechanical hard disk provided by the present invention, both the first preset vibration threshold and the second preset vibration threshold need to be set in advance according to an actual situation, and the first preset vibration threshold and the second preset vibration threshold may be the same or different in size, which is not limited in this embodiment.
According to the mechanical hard disk anti-vibration method provided by the invention, the time difference and the vibration amplitude difference of vibration are detected by the two acceleration sensors, and the automatic switching of the state of the mechanical hard disk can be realized by setting the first preset vibration threshold and the second preset vibration threshold.

and if the first vibration difference value is larger than a first preset vibration threshold value, the control unit controls the mechanical hard disk to be closed, and data information is stored in the storage unit.
Specifically, after a first vibration difference value is obtained, if the first vibration difference value is determined to be greater than a first preset vibration threshold value, it is indicated that harmful vibration occurs, the control unit controls the mechanical hard disk to be closed, and data information is stored in the storage unit to achieve caching of data.
