Embedded project TitlesEnergy Monitoring System Using Sensor Networks in Residential Houses

AbstractThe energy consumption of consumer electronics has been increasing over the past half century. Due to the growing importance of energy saving, many researches about the energy savings of information and communication technology have been presented. Providing residents with information on their energy use has become a feasible option to promote energy savings in the residential sector. In this paper, a home energy management system, particularly an energy monitoring system using sensor networks, is described. The authors designed and developed a smart power strip sensor network and evaluated its accuracy and energy saving efficiency. The conflict between cooperation in distributed state estimation and the resulting leakage of private state information (competitive privacy) is studied for an interconnected two regional transmission organizations (RTOs) model of the grid. Using an information theoretic ratedistortion-leakage (RDL) tradeoff model, each RTO communicates at a rate chosen to optimize an objective function that is dependent on two opposing quantities: a ratedistortion based pricing function that encourages cooperation, and a leakage function that impedes it. It is shown that strictly non-zero pricing incentives are required to achieve non-trivial target distortions This paper presents user-centric energy efficient lighting control architecture for street lamps. The system utilizes ZigBee technology to implement wireless mesh network of street lamps. The coordinator, serving as gateway between ZigBee nodes and internet, relays information of interests to remote user. The proposed system comprises of LED lamps, gateway node, and management software that offer remote monitoring and control of the lamps. Each LED lamp is integrated with ZigBee

Low cost weather station with Applied This work describes use a PC to control home remote control Machine weather station and visualization measuring data via applications written in programming Intelligence language C# with communications via USB or RS232. Weather station is capable of measure temperature up to five temperature sensors DS18B20, wind speed via measuring turbine with optical encoder, the intensity of illumination via light sensitive element and finally is able to detect an approaching thunderstorm by measuring atmospheric charge. The station also disposing eight galvanic separation switch outputs, whose function in the supplied software set to customer requirements. Visualization is done in the charts for each measured quantity and also in arranged the panel, depicting the actual situation Design optimization of TRIACApplied A LED lighting system becomes a promising dimmable AC-DC converter in Power alternative as a substitute of fluorescent and LED lighting Electronics incandescent lights due to high light efficacy and long lifetime. The proposed AC-DC converter implements TRIAC dimming with smooth brightness control. While controlling TRIAC dimming, LED current is regulated by primary side regulation (PSR) to save BOM cost such as LED current sensing circuit and optocoupler. Compact active damper is also applied to stabilize converter operation during dimmer firing with better efficiency and minimized components. The linear frequency control reduces conduction loss and guarantees DCM operation in the wide range of output voltage, which shows excellent power factor correction in single stage flyback topology. The proposed TRIAC-dimming PSR converter has been experimentally verified in 7W LED lighting system Design for Middle-Way of The narrow of land and large population the Automation Intelligent Energy-Saving System resource of Taiwan mainly depended on import with Embedded System from foreign countries and the ratio reaches to #62, Jeenis Road, 1st Floor, Saidapet, Land Mark: Opp. Post Office Chennai-600015.

ARANHA TECHNOLOGIES99.39% [1], which was 5.38% more than that of last year. According to the 2010 statistics of Energy Bureau of Taiwan Ministry of Economy, [2], the energy consumption inner the island was about, 12.03 billion kiloliter oil, which was 6.40% more than that of last year. Meanwhile the electricity consumption was 10.3 Kilodegree, which was 7.32% more than that of last year [3]. Nowadays Taiwan was stepping forward to WTO and Green Island, and it faced the continue progress of industry and more and more energy requirements, oil price instable, the limitation of electricity consumption in summer, and manage to the green house problem of earth, besides, the cost of developing green energy was too high, so how to get to energy-saving becomes one more important issue. The Design of the Steering Wheel The paper described a design of steering wheel Automation with Anti-fatigue Driving for with anti-fatigue driving function. This design Vehicles Based on Pattern utilizes pattern recognition technology, was set Recognition transformer angular displacement sensor, GPS module and embedded system in the steering wheel. The transformer angular displacement sensor used to collect corner voltage changes of steering wheel. Then the embedded system executes pattern recognition to waveform that consisting by continuously varying voltage, in order to determine the driver fatigue. The system also uses changes of GPS data to determine the state in the vehicle such as stop or action, in order to control the algorithm periods of continuous driving time. Finally, the system provides early warning for fatigue driving combining these two parameters Design of Distributed Greenhouse In this paper, a kind of automatic monitor and Automation Big Awning Monitoring System control system of temperature and humidity Based on Field-bus parameter in greenhouse big awning based on CAN bus communication network and TMS320F2812 is designed, hardware architecture of CAN intelligence node and data acquisition system and software design are introduced.

Design and Development of Mamdani-Like Fuzzy Control Algorithm for a Wheeled Human-

Chock temperature control is an important issue in cold rolling mills. Traditional wired systems don't offer satisfactory results for practical use. Because of very low power consumption using Zigbee (IEEE 802.15.4) wireless technology, temperature sensors (up to 125 C ) suitable for a tandem cold mill environment have been developed. The complete monitoring system includes repeaters, a base receiver with transmission control protocol/Internet protocol (TCP/IP) gateway, and a maintenance software. The results obtained in the tandem mill are collected. According to the characteristics of coal mine environment, in this paper we propose a multiparameter wireless sensor network monitoring system based on Zigbee technology for coal mine tunnel. The system can real-time monitor the underground environment and production parameters and intelligently give early warning by using a variety of sensors and wireless sensor network. It is flexible to add sensors and enhance stability of monitoring computer software through RS-485 communication protocol and hardware modular. Experiments have proved feasibility and good stability of the system. This paper describes the ISRobotCar, an experimental autonomous electric vehicle that integrates Robot Operating System (ROS) and several sensors such as IBEO laserscanner, Inertial Measurement Unit (IMU), RTK-GPS, vision cameras, and magnet detectors for magnetic guidance. The development of a power steering controller and of a fuzzy pathfollowing controller are particularly addressed. Finally simulations and experimental results of autonomous path-following control are presented. A wheeled human-conveyance vehicle (WHCV) with a low-level microprocessor is realized in
