Traffic accident recorder and recording method

Abstract

The invention discloses a traffic accident recorder, which comprises an embedded processor, a system interface module, a sensor, an internal storage, a memory controller, an external storage, an ATA bus, a PCI bus and a video recorder. The video recorder transmits video data recorded to the internal storage through the PCI bus; the internal storage is connected with the embedded processor, the ATA bus, the PCI bus through the memory controller respectively; the sensor is connected with the embedded processor through the system interface module to output environmental information collected to the embedded processor through the system interface module so as to judge unexpected accidents; when an accident happens, the corresponding video data in the internal storage is stored in the external storage by the embedded processor through the ATA bus. The invention can record the occurrence process of the accident timely and promptly when the traffic accident happens.
