Multi-system audio resource management method

Abstract

The invention discloses a multi-system audio resource management method. The method is realized through the following steps: A, initializing a system; b, designing any system as a first system, wherein the first system carries out initialization operation on the hardware; c, outputting the hardware by the first system, and outputting the hardware by other systems through the first system; d, if the system for outputting the hardware is abnormal, assigning any other normal system to output the hardware according to a certain sequence rule; and E, if the system for outputting the hardware is abnormal, restarting the system, and outputting the hardware through the newly specified system in the step D after restarting. Compared with the prior art, the method has the advantages that multiple systems do not need to be limited to be a unified kernel, a certain system does not need to be limited to be a main system, any system is abnormal, audio management and output cannot be affected, software is used for dynamically conducting audio management switching, seamless switching can be achieved, the user experience is better, hardware switching is not used, and the hardware cost is reduced.

Description

technical field [0001] The present invention relates to an intelligent Internet of Vehicles or a home entertainment system, and more specifically to a multi-system audio resource management method. Background technique [0002] The Internet of Vehicles covers mobile Internet, Internet of Things, manufacturing vehicles, intelligent transportation and other fields, that is, the Internet of Vehicles integrates many of the above-mentioned technical fields. The Internet of Vehicles should be the networking and intelligence of people, vehicles and roads. The Internet of Vehicles helps to make cars safer, more comfortable and smoother during driving. At present, the main service provided by the vehicle network to car owners is a comprehensive service system integrating navigation, safety, communication, life information and entertainment. The Internet of Vehicles can also provide services such as remote diagnosis and emergency diagnosis, and the in-vehicle communication can provi...

Problems solved by technology

[0003] The audio management of a single system cannot meet the growing entertainment needs of today's users. Using a hardware switch is not convenient enough to allow users to seamlessly switch between multiple systems. Among the existing solutions, Kernel is the most The core part of an operating system, which consists of those parts of the operating system that manage memory, files, peripherals, and system resources. The operating system kernel usually runs processes and provides inter-process communication

[0004] There are already some solutions on the market. All the operating systems in the multi-system must rely on the same kernel. If the kernel is abnormal, the sound output system will not be able to output sound, and the traditional design limits that all systems must be An operating system limited to the linux kernel
