摘 要：设计一种基于lin总线的语音控制智能家居系统，该系统采取分布式控制方式，即一个中央处理器，多个从机组成控制网络。在本系统中，我们采取凌阳SPCE061A作为中央处理器，51单片机作为从机。由凌阳SPCE061A对语音命令进行识别，识别结果通过LIN总线传给特定的从机，再由从机执行对家电操作。语音识别部分采用特定人识别和命令分层技术，系统对家庭的各个成员语音命令进行采样，存储，从而实现家庭各个成员的语音识别。

Substract: Design a speach recognition intelligent household system which is base
on LIN bus, this system use control of distributing, it means one central processor and other subordinate processors make up the control net. In this system, We use SPCE061A as the central processor, 51 MCU as the subordinate processor .The main task of central is speach recognition, then pass the result to subordinate processors by LIN bus, the subordinate processors carry out the handle. In the speach recognition, we use the specified people recognition and command layered technology, the system carry out the sampling of sound command, storing, and then achieve the speach recognition of the home people.
KEY WORDS: Intelligent household system Distributing control
Sound recognition LIN bus Specified people Layered command
