Vehicle-mounted multifunctional device and method for making embedded operating system thereof

Abstract

The invention relates to a vehicle-mounted multifunctional device and a method for making an embedded operating system thereof. The invention designs a vehicle-mounted recreational and reversing monitoring multifunctional information system. The vehicle-mounted multifunctional device comprises a video-audio information receiving unit, a camera shooting monitoring unit, a microprocessing unit and a display control unit; and in the method, the microprocessing unit and a computer are used for building the embedded operating system through programs and programming the embedded operating system ona flash memory of the microprocessing unit. The invention simultaneously has the functions of video-audio recreation and real-time video monitoring on images behind the vehicle, the operation is realized through a touch screen; the operating mode is simple, convenient and visual; the functions and operations to be finished can be clearly and directly displayed, thus increasing simplicity and comfort of the operation; and the invention can be widely applied to various vehicles, especially applicable to passenger cars and small cars, thus being an ideal device for guaranteeing traveling safety and recreation enjoyment.

Description

technical field [0001] The invention belongs to the technical field of vehicle information systems, and in particular relates to a multifunctional information system for vehicle entertainment and reversing monitoring. Background technique [0002] With the development of the national economy and the continuous improvement of people's living standards, the utilization rate of automobiles as a means of transportation and means of transportation continues to increase, and people's requirements for automobiles are also increasing, not only requiring the safety of driving and reversing on increasingly crowded roads , effectively avoid accidents, and require rich audio-visual audio-visual enjoyment in the boring driving process. At the same time, with the continuous development of automobile technology and information technology, people's demand for multifunctional vehicles is increasing day by day, so it is of great significance to develop a multifunctional information system for...

AI Technical Summary

Problems solved by technology

The main disadvantages of this device are: ①You can only choose one after watching TV or monitoring the car, and you can’t realize the two functions of audio-visual playback and reversing monitoring at the same time

②Audio and audio playback can only play the audio and video information stored on the disc, and it needs to be equipped with a disc box on the vehicle and needs to carry a large number of discs. On the other hand, playing audio and video discs for a long time will cause disc wear and damage to the movement serious consequences

The main disadvantages of this player are: ① It can obtain video and audio files from the computer network and mobile storage devices to meet people's audio-visual audio-visual needs, but it cannot monitor the situation behind the car and cannot determine driving safety.

② It needs to be used with multimedia equipment, such cumbersome connections occupy the original space and increase the cost of the equipment
