ABSTRACT: The objective of this research was to increase the independence and safety of the sight impaired by developing an enhanced travel aid in the form of a sensor embedded long cane to reduce the risk of injury from walking into suspended or overhanging objects while providing the sight impaired community with a familiar and well accepted tool. Prior research at the Electromechanical Systems Laboratory had established a theoretical framework for ultrasound-based ranging and spatial obstacle localization from the moving reference frame of a long-cane. A prototype was implemented using analog threshold detection techniques. This research focused on a new approach. A coded pulse was transmitted and correlation techniques were used to identify echoes and determine time of flight. Compared to the prior effort this new approach was more sensitive, had greater noise immunity, and provide greater spatial resolution for obstacle detection. The first step in the coded pulse approach was to generate a transmit pulse with an embedded binary code that is highly distinguishable. A transmit pulse generated by phase modulating a 40 kHz carrier signal with a 13-bit Barker code word, with each bit consisting of 4 cycles of the 40 kHz carrier was used. Digitized representative echoes were used as reference vectors for correlation to account for the effect of the impulse responses of the transducers, the air, and the reflection, on the transmitted pulse. In a detection cycle, the coded pulse was transmitted; the A/D converters took 2600 samples at the 150 kHz sampling rate to capture any echoes from objects between 1 and 4 meters in front of the cane. The receiver data was cross-correlated with the stored echo image to find echoes in the received signal. The correlation peak positions from the upper receiver were then compared to the peak positions from the lower receiver and if they collaborated within the synthetic aperture, the range and height were calculated annunciation was made by a synthesized voice. The new obstacle detection system described above was designed and a prototype was constructed and embedded into the shaft of an 18 mm diameter body of a long cane. Introduction

Abstract- The aim of this paper is to design a poly house monitoring based on the IoT. A poly limits, a message will be sent on mobile app through wifi router. Temperature and humidity are controlled by humidity and temperature sensors and a fogger used to control the same. The irrigation of agriculture field is carried out using automatic drip irrigation, which house is a covered area where plants grow and cultivate. There are some important parameters to be monitored inside the poly house are temperature, relative humidity and soil moisture. The temperature, humidity and soil moisture are sensed by NOD MCU. If any condition crosses certain operates accordingly so as optimal amount of water is applied to the plants.

 Abstract

Abstract This paper presents a modelling method of photovoltaic systems (SPR305E-WHT) and an implementation and comparison of three MPPT techniques ,fuzzy logic control, incremental conductance ,perturb observe method for maximum power point tracking (MPPT) algorithm. The method is used to study the influence of rapidly changing irradiance level concerning performance of 10KW photovoltaic systems. A simple circuit model of the boost converter connected to the photovoltaic systems is used to easily simulate the incremental conductance MPPT method. The model has been implemented in MATLAB / Simulink 2013 . The simulation results are presented and analysed to validate that the proposed simulation model is effective for MPPT control of the photovoltaic systems at rapidly changing irradiation condition.

Abstract-In this paper, the realization of the energy management and control subsystem of a grid-connected wind/solar hybrid power system has been introduced. The hybrid power system is based on multi-agents theory, so the control subsystem is regarded as an agent. It is composed of programmable logic controller (PLC), human-machine interface (HMI), grid-connected control module, AC multi-function electric power meters, DC electric power meters, RS485/TCP converter etc., to control and manage the operation of multi-source, such as power grid, wind turbine generation, solar photovoltaic, storage batteries and loads, also to acquire data and communicate with others. In this paper we put the emphases on its hardware, communication and how to meet its requests and functions. Experiments show that this system is competent for both grid-connected mode and stand-alone mode.

 Abstract

Abstract Wind energy has gained an increasing worldwide interest due to the continuous increase in fuel cost and the need to have a clean source of energy. The main objective of most of the wind energy systems is to extract the maximum power available in the wind stream. In order to achieve maximum power point tracking (MPPT) for wind power generation systems, the rotating speed of wind turbines should be adjusted in the real time according to wind speeds. In this paper, we will be focusing on some of the revolutionary changes that took place in the control scheme of wind energy which has got enough potential to meet the energy requirements of the world in the present scenario. When we are deficit of the natural resources like coal, water etc. Thus presently it serves as the most reliable source of energy for our future generations.
