城镇化进程加快和居民生活水平提升,智能厨电系统在节能、环保与智能化方面的需求将日益增强。针对传统厨电控制系统存在的能耗高、响应慢及智能化程度不足等问题,提出一套以智能触控模块、变频驱动模块与智能感知与通信模块为核心架构的智能厨电控制系统。该系统融合多项前沿技术,首先,将电容式触控技术与红外挥手感应进行交互,为精准、耐用的非接触控制奠定基础;其次,基于智能功率模块(intelligent power module,IPM)构建高效的交-直-交变频驱动电路,通过空间矢量脉宽调制(space vector pulse width modulation,SVPWM)与模糊控制算法,实现电机的软启动、无级调速与按需供能,以降低系统运行能耗;然后,将多种环境传感器与语音识别模块进行集成,并借助物联网技术,以实现对环境状态的实时监测、多模态用户意图的协同判断与冲突消解,及设备间的智能联动,为主动安全防护闭环的建立提供保障。最后,对各模块进行软硬件设计、加工,建立系统样机并进行主要性能测试。实验结果表明,该系统输出效率、响应时间、待机功耗及触控准确率等性能指标良好,具备较好的实用性与推广价值。
With the acceleration of urbanization and the continuous improvement of residents′living standards,the demand for smart kitchen appliance systems in terms of energy saving,environmental protection,and intelligence is increasingly enhanced.To address the issues of high energy consumption,slow response,and insufficient intelligence in traditional kitchen appliance control systems,a smart kitchen appliance control system with an intelligent touch-control module,a variable-frequency drive module,and an intelligent sensing and communication module as its core architecture is proposed.Multiple cutting-edge technologies are integrated into this system.Firstly,capacitive touch technology and infrared gesture sensing are integrated for interaction,laying the foundation for accurate and durable noncontact control.Secondly,an efficient AC-DC-AC variable-frequency drive circuit is constructed based on an intelligent power module(IPM).Through the application of space vector pulse width modulation(SVPWM)and fuzzy control algorithms,soft starting,stepless speed regulation,and on-demand power supply for the motor are realized,thereby reducing the operational energy consumption of the system.Subsequently,various environmental sensors and a voice recognition module are integrated.Leveraging IoT technology,real-time monitoring of environmental status,collaborative judgment and conflict resolution of multi-modal user intentions,and intelligent linkage between devices are achieved,thereby establishing a proactive safety protection loop.Finally,the hardware and software for each module are designed and processed,a system prototype is established,and main performance tests are conducted.Experimental results demonstrate that key performance indicators such as system output efficiency,response time,standby power consumption,and touch accuracy are significantly improved,indicating good practicality and value.
