Home energy management leveraging open IoT protocol stack

Abstract: The demand for energy is ever increasing thanks to population growth and industrial development. Efficient energy management at home will be possible provided there is an increased awareness among consumers on their consumption patterns and effective use of their appliances. In India, utility companies continue to gather much of the energy utilization data manually and the automation in home energy metering is yet to be achieved as the smart meter adoption is still in its early stages. While addressing automation in home energy management, it is important to consider solutions that meet country-specific needs like energy costs, fair billing, electricity thefts, system scalability and reliability. In this paper, we present a prototype implementation for home energy management and control, leveraging Internet of Things protocol stack comprising emerging IETF standards such as 6Lo WPAN, RPL and CoAP. The open standards based approach enables seamless integration of the appliances at home to the existing internet infrastructure making remote monitoring, control and data collection over the web possible. Further, enabling IPv6 connectivity to the energy meter leads to better integration of the Data Management Systems of utilities unlike some of the existing proprietary solutions. In our IoT based and IPv6 network connected system, we have a PV panel to generate electricity for DC appliances apart from the main 230V AC supply. Considering the fact that energy supply from renewable sources is intermittent, we provide users with an option of choosing either of the energy sources over the internet. Wireless node based on CC2538 System-on-Chip is interfaced with an energy meter connected to the main AC supply, providing 2 way communications between the utility and the consumer over the internet. The sensor nodes are also used to measure the power consumed by the DC appliances and remote actuation control. Further, a timing based approach is provided for consumers to "turn on" appliances at preset time periods. All the data collected by the sensor nodes are communicated in real time over the internet to the utility and consumer via a border router.

Power consumption management control system and method

Abstract: The invention provides power consumption management and control system and method, used for controlling the total power consumption of an electric system at a time point to be lower than a threshold value A user works out a reasonable power meter readings or power consumption in a unit cycle and sets the reasonable power meter readings or power consumption to a power consumption management and control module; and then, the power consumption management and control module carries out dynamic adjustment and distribution of the power utilization structure of the user in one unit cycle according to the set budget of power meter readings or power consumption

Front entry electric meter lock

Abstract: This device provides greater ease in locking and unlocking the means provided in my prior U.S. Pat. No. 3,867,822 for securing electric meters from tampering. The key enters from the front of the meter box instead of from the side.

Low-voltage power line communication network constructing method for power meter reading system

Abstract: The invention discloses a low-voltage power line communication network constructing method for a power meter reading system. A constructed low-voltage power line communication network comprises a concentrator, a carrier power meter and a collector; wherein the collector and the carrier power meter are used as terminals for each level; the low-voltage power line communication network construction is completed in three steps: logical layering, communication topology construction and communication routing selection; the logical layering comprises establishing logical layers according to the length of the electrical distance between the terminals in each level, and respectively marking and attributing the collector and the carrier power meter into different levels; and the communication topology construction comprises storing the IP of the two terminals and the electrical distance into the concentrator under the condition that the electrical distance of the two terminals between the upperlevel and the lower level is less than or equal to L, thereby optimizing the network topology. In addition, the invention adopts a communication routing reconstruction method for the carrier power meter with failure, thereby realizing the timely updating and troubleshooting of the network topology.
