摘　　要：为了使照明系统的智能化控制更加满足人们的多样化需求,设计了一款以语音控制为基础的智能家用情景照明系统,并以此为例分析基于LD3320的语音控制系统。智能家用情景照明系统以STC11L08XE为核心、以语音信号作为操作指令,可实现自动调光模式和情景模式两种模式的转换。自动调光模式综合考虑自然光亮度和用户实际需求,采用脉冲宽度调制(PWM)技术动态设置灯组的照度,充分利用自然光节约能源,达到当前环境下最舒适的室内照度。情景模式则根据情景需求设置灯光亮度和颜色,从而营造氛围、提高用户生活品质。仿真结果表明,该系统与市场上大部分光照系统相比,造价低廉、实用性强。该系统但仍存在集成度不高的问题,未来发展考虑硬件模块化。To make the intelligent control of lighting system more meet people’s diversified needs, voice control has become a necessary means to facilitate people’s life. An intelligent home lighting system based on voice control is designed, and the voice control system based on LD3320 is analyzed as an example. This intelligent home scenario lighting system uses STC11L08XE as the core and voice signal as the operation command, which can realize two modes of automatic dimming mode and scenario mode conversion. The automatic dimming mode takes into account the natural light brightness and the actual needs of users, and uses pulse width modulation(PWM) technology to dynamically set the illumination level of the lamp set, making full use of natural light to save energy and achieve the most comfortable indoor illumination level in the current environment. The scenario mode sets the light brightness and color according to the scenario needs to create an atmosphere and improve the quality of life of users. Simulation results show that the brightness requirements of the light set in various scenario modes reach the expected level. The system is inexpensive and practical compared to most lighting systems on the market. However, there is still the problem of low integration, and future development considers hardware modularity.
