智能家居控制装置的设计与实现

针对现有智能家居控制系统存在人机交互不便、便携性与兼容性比较差等缺点,设计一种以STM32微控制器为控制核心的智能家居控制装置。该装置采用主机与执行模块分离,通过无线WiFi进行通信;执行模块利用红外线与继电器实现对家居的控制;主机采集家电的遥控器发出的红外线波形,再把原样波形的数据传输给执行模块来控制家电设备;采用PWM等效电压控制方法来调整PWM信号占空比,实现光立方的立体动态显示;使用语音识别与光立方模块进行立体动态显示和语音反馈。经实验测试表明,该装置实现了对智能家居的有效控制,具有较好的兼容性与便携性,克服了现有装置的缺点。

Design and realization of Intelligent Home Control Device

According to the existing Intelligent Home Control System,there are disadvantages such as inconvenience of man-machine interaction,poor portability and compatibility.a type of Intelligent Home Control device adopting STM32 microprocessor as the control center is designed.The host and execution module are separated,and communicate through WiFi.The Infrared ray and relay are used to control the Intelligent Home by the execution module.The host collects the infrared wave emitted by the remote control of the home,and then transmits the data of the original waveform to the execution module to control the home appliances.The PWM equivalent voltage control method is used to adjust the duty cycle ratio of PWM signal to realize the stereo dynamic display of light cube.Speech recognition and light cube module are used for stereo dynamic display and speech feedback.The test results show that the device can effectively control the household,and has good compatibility and portability,and overcomes the shortcomings of the existing devices.
