【摘要】：当今，汽车工业和电子工业的正在高速发展，而汽车音响领域同时也不断的完善和创新。汽车上运用最古老的电子产品便是汽车音响，汽车音响不断的升级，已由最早先的汽车收音机变化为娱乐、视听、导航、通讯、多功能相统一的综合性多媒体电子系统，也构成将来汽车上不可或缺的组成部分。日本ALPINE公司作为世界知名汽车音响生产商之一，依靠其非凡的质量保证、优易的性价比在国际市场上占有重要地位。 汽车音响作为汽车的一个不可或缺组成部件，以保证汽车功能正常使用为前提，提供用户以高品质的声音体验是汽车音响的主要任务。现有ALPINE的汽车音响声音处理系统是采用NEC V850SG2系列单片机C语言控制CXD2729Q DSP处理芯片，选取先进的数据多媒体技术，包括数据信号处理、数字声音合成技术，具有优良的可移植性和可靠性。 本文主要讨论ALPINE的DVD，，或称Digital Versatile Disc(数字多用途光盘))模块中童锁模块设计。DVD模块是整体系统中一个非常重要部分，DVD模块直接与各个软硬件和模块相关相结合，运用了ALPINE开发汽车音响软件必要的技术。DVD模块的机制是播放DVD\MP3\CD给用户。APP模块是DVD模块的应用层，用来判断外部来的命令是否能够进行处理，如果可以处理在发给DRVL1模块,在DRVL1模块转换成具体应该做的命令再继续向下一层发命令。程序设计依据SWEPF思想开发。开发语言使用NEC V850SG2系列单片机C语言。
[Abstract]:Nowadays, the automobile industry and electronic industry are developing at high speed, and the field of automobile sound is constantly improving and innovating. The oldest electronic product used in the automobile is the car stereo. The car sound has been continuously upgraded from the earliest car radio to an integrated multimedia electronic system of entertainment, audiovisual, navigation, communication, and multifunction. It also forms an integral part of the future car. As one of the world famous automobile acoustics manufacturers, Japan ALPINE Company relies on its extraordinary quality assurance, and its performance and price ratio occupies an important position in the international market. As an indispensable component of automobile, automobile audio is the main task of automobile audio system, which is based on the premise of ensuring the normal use of automobile function and providing users with high quality sound experience. In the present ALPINE sound processing system of automobile sound, the CXD2729Q DSP processing chip is controlled by C language of NEC V850SG2 series single chip computer, and advanced data multimedia technology, including data signal processing, digital sound synthesis technology, is selected. It has excellent portability and reliability. This paper mainly discusses the design of the child lock module in the ALPINE DVD, (or Digital Versatile Disc (Digital Multipurpose Disc) module. The DVD module is a very important part of the whole system, and the DVD module is directly combined with the hardware and software and the module correlation. The mechanism of DVD module is to play DVD\ MP3\ CD to user. APP module is the application layer of DVD module, which is used to judge whether external commands can be processed. If you can handle the issue in the DRVL1 module, the DRVL1 module is converted to the specific command that should be done before continuing to issue the next command. The program is designed according to the idea of SWEPF. The development language uses NEC V850SG2 series single-chip computer C language.
