2 Energy consumption in Japan Can be divided into 3 sectors Have been increasing over the past half century Mainly due to increasing population and economic development Although development of new low-consumption appliances contribute in no small part to reducing the emission of greenhouse gases, remember the recent rapid growth in comfort services is resulting in high power consumption. 1

3 EMS (Energy Management System) Although there has been research, integrating a new device and developing an appropriate system are not easy. Difficult to satisfy those who have different lifestyles Key feature of next generation EMS is Adaptability If several multi-vendor sensors/actuators in heterogeneous networks are able to communicate, information could be extensively used by various devices. HEMS -Green by ICT - Solar panel Electric power plant Electricity Remote maintenance/control LED lighting f Flat panel Adiabatic wall Double paned window Hot water Control panel Low-consumption appliances City gas, LPG Natural gas pipeline Floor heating Fuel cells 2

4 Adaptive HEMS/BEMS (A-HEMS/BEMS) Dual mode cellular Power line ZigBee A-HEMS unit Controlling energy consumption by convergence of heterogeneous networks PLC, Wi-Fi, Echonet, DLNA, cellular, sensor networks, Although several standards model devices from various perspectives by focusing on different aspects, we used the PUCC specifications. An advantage in discovering services/devices through a structured P2P network If the sensor gateway of another domain Circuit breaker box network acts as the P2P node, the PUCC Sensor / Actuator P2P network allows nodes to access the networks connected network adaptively.

5 Mutual complementary overlay sensor network Home network needs to maintain a communication infrastructure The best way to construct a new home network is to use existing cables or wireless However, the PLC signals are attenuated by different phases and the wireless communication quality is degraded by obstacles, transmission distance, and noise. To solve these problems, we have proposed a mutual complementary overlay sensor network improves the arrival rate by using two different types of media. Many combinations, but we developed one using PLC/ZigBee as prototype Subnet-1 Subnet-2 Subnet-3 Inter-subnet routing Router Router ZigBee PLC ZigBee Intra-subnet routing 0x02 0x01 ZigBee PAN1 0x03 0x01 0x02 PLC Network 1 0x01 0x02 ZigBee PAN2 Heterogeneous networks 4

6 Prototype hardware platform a) Main application board b) Enhancement interface board c) ZigBee sensor node Various evaluation boards and several enhancement modules to deploy mutual complementary overlay sensor network for A-HEMS/BEMS Temperature, illuminance, and motion Enhancement modules that can be connected through enhancement board Humidity sensor, infrared remote control module, smart meter, smart switch Enable conventional appliances without telecommunication capabilities to connect Allows users to construct a control environment easily, cheaply, and without the need for information appliances 5

7 Prototype implementation Mutual complementary sensor/actuator overlay sensor network Sink node Sensor gateway Sensing data recorder PostgreSQL Cordinator node Actuator controller Web server Sensor node - temperature - humidity - illuminance - power meter - motion Actuator node -Infrared remote control Web browser Mobile phone Event Action settings Although the PUCC P2P nodes are the sensor gateway and the mobile phone, we can freely configure the cooperative behavior of sensors and actuators from a mobile phone. Easy to integrate other new vendor devices after deployment and to develop an appropriate system for those who have different lifestyles 6

8 Example of user interface Cellular phone Start screen Event definition Select the sensors the user wants to set a event Action settings Select each element (to generate a event condition) ex) illuminance > 300 lx BRIGHT!! Send subscribe message Sensor gateway Event parsing module Parse a event condition sent from the client, and determine whether the event occurs. Condition1 App & Use event-tree Condition2 The event occurs Generate GUI based on metadata gateways have Gateway Device metadata Service metadata Select the event you defined Send subscribe message Condition1 App & Condition2 Determine whether the event occurs based on the event-tree generated by this module. 7
