Shock-proof method and system of vehicle-mounted mechanical hard disk and vehicle-mounted recording device

Abstract

Provided in the invention is a shock-proof method of a vehicle-mounted mechanical hard disk. The method is applied to a vehicle-mounted recording device containing an electronic storage medium. The method comprises: vibration warning zone information is obtained; if a current vehicle is driven into the vibration warning zone, the vehicle-mounted recording device uses the electronic storage medium to carry out recording and storage; if the current vehicle is driven out of the vibration warning zone, the vehicle-mounted recording device uses a mechanical hard disk to carry out recording and storage. According to the technical scheme provided by the embodiment of the invention, the vehicle-mounted recording device can get vibration zone information in advance and thus switches the mechanical hard disk to the electronic storage medium in advance, thereby substantially prolonging the service life of the mechanical hard disk in the vehicle-mounted recording device. Besides, because the electronic storage medium is only used for buffering, the capacity is low, so that the device cost is increased little.

Description

technical field [0001] The invention relates to the technical field of anti-vibration, in particular to a method and system for anti-vibration of a vehicle-mounted mechanical hard disk and a vehicle-mounted video recording device. Background technique [0002] Vehicle-mounted video recorders, as special video recording equipment on cars, are more and more commonly installed and used on buses and coaches. But at present, the hard disk damage rate of the car video recorder is very high. This is because the hard disk is greatly affected by the vibration of the vehicle during the read and write operation, which may easily cause the failure of the hard disk head hitting the disk. However, vehicle-mounted video recorders are generally placed on the car, which is inevitably affected by the road surface, and vibration is inevitable. [0003] In the prior art, there have been many considerations on the anti-vibration aspect of the vehicle-mounted video recorder. For example, steel...

Problems solved by technology

Although these anti-vibration technologies from the hardware structure can reduce the vibration of the hard disk, they still cannot avoid the vibration during the process of reading and writing the hard disk; in some environments with relatively large vibrations, the hard disk may still be damaged
