摘要
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.
