High temperature protection method and system for audio system and automobile

Abstract

The invention discloses a high temperature protection method of a sound equipment system. The method comprises the following steps of detecting a current temperature in a sound equipment component; comparing a current temperature value to at least two preset temperature intervals corresponding to cooling measures with different cooling efficiency respectively; determining the preset temperature interval where the current temperature value belongs; and executing the cooling measures corresponding to the preset temperature interval where the current temperature value belongs. By using the high temperature protection method, according to a heatproof capability and a temperature influence degree in the sound equipment component, the preset temperature intervals are divided; and after the preset temperature interval where the current temperature value belongs is determined, the corresponding cooling measures are executed. An internal portion of the sound equipment component is cooled in a targeted mode. Under the condition that the sound equipment system is prevented from high temperature damages, cooling control precision and a passenger experience are increased. The invention also discloses a high temperature protection system of the sound equipment system and an automobile including the high temperature protection system of the sound equipment system.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a high temperature protection method for an audio system. The invention also relates to a high temperature protection system of an audio system and an automobile. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] As a pillar industry of the machinery industry, the automobile industry has matured day by day. There are various parts, mechanisms and assemblies in a car, and the number of parts can reach tens of thousands. According to the different working methods and working environments of various parts, they are generally divided into multiple systems, such as starting system, ignition system, lubrication system, cooling system and fuel supply system, etc., and the main services for passengers in the car are audio systems, etc. . [0004] The audio system mainly in...

AI Technical Summary

Problems solved by technology

Although this high temperature protection method can effectively prevent damage to the audio system, the cooling method is too general, single and rough, ignoring the heat resistance of the audio components themselves and the cooling of each component

And the sound system was suddenly turned off during operation, resulting in a poor experience for the occupants
