适用于自动需求响应的分体式智能用电测控终端

能源互联网中自动需求响应(Automated Demand Response, ADR)的实现离不开对终端用电设备的准确测控。为解决目前智能用电终端控制方式缺乏灵活性及数据采集处理能力偏弱的问题,研制了具备数字信号处理与红外精准控制功能的分体式智能用电监测控制终端。装置由装置本体和红外控制器两个分立的部分组成,其中装置本体包含DSP芯片、电气采样电路、ADC芯片、WiFi模块、ZigBee模块和温湿度传感器,红外控制器包含单片机、ZigBee模块、红外编码与收发模块以及锂离子电池。装置本体根据采集的用电和环境信息、综合需求响应要求向红外控制器下达指令,进而准确调整负荷电器运行状态。得益于分体式与可充电设计,此终端可适应复杂家居环境,为实现有效的家庭能量管理、推动家庭负荷参与需求响应(尤其是ADR)打下硬件基础。

Split-type smart power measurement and control terminal for automated demand response

The implementation of Automated Demand Response (ADR) in Energy Internet is inseparable from accurate measurement and control of the terminal electrical appliances. To resolve the shortcomings of current intelligent power terminal control methods, such as lack of control flexibility and weak data acquisition and processing capabilities, a split-type intelligent power measurement and control terminal with digital signal processing and infrared precision control functions is developed in this paper. This device contains two separate parts:the device body and the infrared controller. Among these, the device body comprises a DSP chip, an electrical sampling circuit, an ADC chip, a WiFi module, a ZigBee module and a temperature-humidity sensor. The infrared controller includes a MCU, a ZigBee module, several infrared encoding, receiving and transmitting modules, and some lithium-ion batteries. The device body provides commands to the infrared controller according to the collected power and environmental information and the comprehensive Demand Response (DR) request, thereby accurately adjusting the operating status of the power load devices. Due to the split and rechargeable design, this terminal can adapt to a complex home environment, laying the hardware foundation for effective home energy management and household loads participation in DR, especially ADR.
