Vehicle data black box with reflective properties and working method thereof

Abstract

The invention discloses a vehicle data black box with reflective properties and a working method thereof, relates to the technical field of intelligent transportation, Internet of vehicles, cloud computing and mobile Internet, and has the following technical key points: the vehicle data black box with reflective properties includes a sensing part for monitoring and transmitting vehicle data, a data part for storing vehicle data information and a power source part for providing electric energy; the data part includes a protective storage module having high temperature resistance, and the protective storage module includes a nano-thermal insulation material, a phase change housing and a phase change liquid; and a housing is arranged outside the black box and a reflective layer is arranged outside the housing. According to vehicle driving data, the vehicle data black box with reflective properties can determine a vehicle driving state comprehensively in real time. The data sensing part independently stores and uploads data information of a vehicle in an abnormal driving state monitored by the sensing part during a period of the occurrence of the abnormal driving state and during a period of after the occurrence of the abnormal driving state to a platform server. Meanwhile, a backup power source of the power source part provides emergency power in a state of a power failure. The vehicle data black box with reflective properties and the working method thereof have the characteristics of well protecting and conveniently searching vehicle stored data.

Description

technical field [0001] The invention relates to the technical fields of intelligent transportation, Internet of Vehicles, cloud computing and mobile Internet, more specifically, it relates to a vehicle-mounted data black box with reflective properties and a working method thereof. Background technique [0002] The black box is generally suitable for the aircraft field. It has strong fire resistance, pressure resistance, impact vibration resistance, sea water (or kerosene) immersion resistance, and magnetic interference resistance. Even if the aircraft is completely damaged, the recorded data in the black box can be preserved intact. . The causes of most of the air crashes in the world are found out through black boxes. In fact, the core of the "black box" lies in the protection of its data. Generally, all kinds of data collected are recorded through the hard disk. The hard disk mentioned here can be a mechanical hard disk or a solid-state hard disk, and a flash memory, etc....

Problems solved by technology

[0003] Driving recorder There are two common types of driving recorders, one is common and can only be used to record driving video, and has no other functions; the other can record driving data of the vehicle itself in addition to recording driving video; but they Most of the recorded data is stored in the hard disk or TF card, which does not protect the data security very well. If a serious accident occurs to the vehicle, the driving recorder itself and its storage are easily damaged.

[0004] In addition, there is no special mark on the appearance of the current driving recorder. Once a serious accident occurs, it may be wrapped inside the vehicle, which is not easy to find, or the vehicle falls into deep water after an accident. If there is no salvage vehicle operation in a short time conditions, then divers need to salvage the vehicle data black box out of the water first, and the driving recorder without special identification is not conducive to divers' underwater search.
