摘要本文为基于声波识别技术籍以实现开关控制。声控是一个新颖却又经典的控制切入点，本文拟通过声波识别模块识别特定的声音频段来产生响应，进而控制不同的开关进行不同的动作。此技术符合“智能家居”理念，尤其适用于家中有老年人、孕妇等不方便行动的人群使用，发展前景十分明朗。86107

本设计包含架构设计和实现调试两部分。其中架构设计部分为利用protel99 se软件设计出符合要求的操作软件和硬件电路，主要包含有声波识别转化模块、降压电路模块，继电器模块；实现调试部分为焊接硬件电路设计和调试控制软件两步，并做出适当改进。

本文从声波匹配识别响应入手，通过理论研究和硬件搭建实现目标，设计出了能够识别依靠手机发射的特定音频信号来引起响应的开关，实现了楼宇内的智能声控，为给用户带来更智能的居家生活做出了卓有成效的探索。

Abstract This paper is based on the technology of acoustic wave identification to realize the switch control。 Voice control is a novel and classical control point and this paper intends to identify the specific sound frequency band through the acoustic recognition module to make the response, then control the different switches to carry out different actions。 This technology is in line with the concept of Smart Home, especially for the elderly, pregnant women and other people in the home is not easy to use, the development prospects are very clear。

This design includes two parts of the architecture design and implementation。 The part of the architecture of using Protel99 se software design that meet the requirements of the operation of the software and hardware circuit which mainly comprises a sound wave identification conversion module, the step-down circuit module, relay module; debugging part for welding hardware circuit design and debugging of software control step and make appropriate improvement。

This paper from the acoustic matching recognition response which through the theoretical research and the hardware structures to achieve the target design to specific audio signal identification depends on the phone was launched to make the response of the switch, the premises of the intelligent voice to give users a more intelligent home。
