Built-in automobile data recorder architecture of intelligent terminal and implementation method

Abstract

The invention discloses a built-in automobile data recorder architecture of an intelligent terminal and a realization method, and the architecture comprises an application layer which is used for realizing logic control of a built-in automobile data recorder in an APP form; the Native layer is used for processing data acquired by a camera of a built-in automobile data recorder in a service form; the application layer sends a request to the Native layer through the agent layer after obtaining an instruction, and the Native layer obtains data collected by a camera through a system API after receiving the request and correspondingly processes the data according to the request. According to the method, the development efficiency can be effectively improved, and a developer only needs to pay attention to the development of business logic and does not need to pay attention to implementation details of a bottom layer by utilizing system functions supported by the Android system. According to the automobile data recorder, higher-definition camera picture transmission can be realized under the condition that the cost is not increased, and the switching between reading and writing of the USB is much faster than that of an external device due to the fact that a signal transmission link is omitted.

Description

technical field [0001] The invention belongs to the technical field of intelligent cockpits, and more particularly relates to a structure and an implementation method of a built-in driving recorder of an intelligent terminal. Background technique [0002] "Driving Recorder System" Patent No. CN201821643327.0 [0003] "Driving recorder audio and video playback system and driving recorder" patent number CN201220075180.6 [0004] The driving recorder is a device that records relevant information such as images and sounds on the way of the vehicle. The driving recorder stores the video images and sounds of the entire driving process of the car, which can provide evidence for traffic accidents. The dash cam can also be used to record the process of conquering difficult obstacles. While driving, I recorded video while walking, and recorded the time, speed, and location in the video at the same time, which is quite a "black box". It can also be used for DV shooting at home for f...

Problems solved by technology

As an important function of the in-vehicle system, the solution of the external box is particularly obvious. On the one hand, the hardware cost is high; , Interface switching, video playback, and video browsing will all have a large delay, which can be clearly felt by users in operation, and the complaints are relatively large
