Abstract

The invention discloses a high-reliability vehicle-mounted video storage device and a video storage method. The high-reliability vehicle-mounted video storage device comprises a storage unit and a video coding unit, wherein the storage unit comprises a mechanical hard disk storage unit and a flash medium storage unit; and the video coding unit is used for coding a video source to generate a video data stream and respectively storing the video data stream into the mechanical hard disk storage unit and the flash medium storage unit. When a vehicle normally operates, the mechanical hard disk storage ensures that an evidence is taken from an event before a longer time. After malignant accidents such as strenuous vibration occur in the vehicle, if the mechanical hard disk is not used for completely recording the whole process of the event, the flash medium storage can also provide picture recording in the latest period, therefore, the whole process of the malignant accidents is reduced. Meanwhile, the invention can prevent data from synchronously being stored in the storage unit during accident outage.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted video, in particular to a vehicle-mounted video device capable of ensuring effective data recording and a video storage method thereof. Background technique [0002] In the transportation industry, especially the public transportation industry, vehicles are often equipped with vehicle-mounted video devices (that is, vehicle-mounted video recorders) to record video of the inside and outside of the vehicle while driving. In order to achieve the purpose of evidence collection after accidents, disputes, violations of laws and regulations and other abnormal events. In the public transportation industry, the industry standard requires video recording to be stored for a period of time, and generally requires at least 30 days of video data storage. Because the video data of 30 days is relatively large, a large-capacity mechanical hard disk is used as a storage medium for the vehicle-mounted v...
