Parabolic Trough

Due to the complex design and high costs of production, solar thermal systems have fallen behind in the world of alternative energy systems. Different mechanisms are applied to increase the efficiency of the solar collectors and to reduce the cost. Solar tracking system is the most appropriate technology to increase the efficiency of solar collectors as well as solar power plants by tracking the sun timely. In order to maximize the efficiency of collectors, one needs to keep the reflecting surface of parabolic trough collectors perpendicular to the sun rays. For this purpose microcontroller based real time sun tracker is designed which is controlled by an intelligent algorithm using shadow technique. The aim of the research project is to test the solar-to-thermal energy efficiency by tracking parabolic trough collector (PTC). The energy efficiency is determined by measuring the temperature rise of working fluid as it flows through the receiver of the collector when it is properly focused. The design tracker is also simulated to check its accuracy. The main purpose to design this embedded system is to increase the efficiency and reliability of solar plants by reducing size, complexity and cost of product.

A GPS tracking system utilizing the license-free RF communication is proposed as viable alternative to using the available GSM network for low-cost maintenance. The proposed system is designed based on the popular 8-bit embedded system. It consists of a monitoring unit and a remote unit. Each unit is equipped with, among others, a GPS receiver and an RF transceiver as main components. While there is a need for the remote unit to be small and compact, the monitoring unit is also designed as a portable device. Prototypes are built for design verification.

The discriminative object tracking system for unmanned aerial vehicles (UAVs) is widely used in numerous applications. While an ample amount of research has been carried out in this domain, implementing a low computational cost algorithm on a UAV onboard embedded system is still challenging. To address this issue, we propose a low computational complexity discriminative object tracking system for UAVs approach using the patch color group feature (PCGF) framework in this work. The tracking object is separated into several non-overlapping local image patches then the features are extracted into the PCGFs, which consist of the Gaussian mixture model (GMM). The object location is calculated by the similar PCGFs comparison from the previous frame and current frame. The background PCGFs of the object are removed by four directions feature scanning and dynamic threshold comparison, which improve the performance accuracy. In the terms of speed execution, the proposed algorithm accomplished 32.5 frames per second (FPS) on the x64 CPU platform without a GPU accelerator and 17 FPS in Raspberry Pi 4. Therefore, this work could be considered as a good solution for achieving a low computational complexity PCGF algorithm on a UAV onboard embedded system to improve flight times.

The paper outlines an application of smart solar “photovoltaic” power generation. Solar panels are typically in fixed position. They're limited in their energy-generating ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy system, the solar panel should be able to align with sunlight as it changes during a given day. The present paper examines the design advantages of creating an intelligent solar tracking system like a helianthus flower using microcontroller based embedded system.

Now a days, Vehicle tracking system plays a major role in our daily life. As the technology grows, vehicle thefts are increasing enormously. This paper proposes to design an embedded system which is used to track and position any vehicle by using Global Positioning System (GPS) and Global system for mobile communication (GSM). This helps in monitoring and reporting the status of the moving Vehicle on demand continuously. So, ATMEGA328 microcontroller is serially interfaced to a GSM Modem and GPS Receiver through serial communication protocol RS 232. In this, driver circuit is used to covert TTL voltages into RS 232 voltage levels. Identifying the position of the remote vehicle is done by GPS modem continuously. The current location details like vehicle longitudes and latitudes of the remote vehicle is sent through GSM modem. The output is acquired from GPS modem and displayed on the LCD display. The same data is transmitted to the mobile at the other end from where the position of the vehicle is demanded. Based on the request placed by the user, the position of the vehicle is automatically sent to the corresponding mobile number. So, this project has been implemented to identify lost vehicle, know the status of moving vehicle from remote location and send the information to the user's mobile number.

A solar tracker is a system that is used for the mechanical orientation of solar payloads (collectors and photovoltaic panels) towards the sun. A simple, low-cost, but effective open-loop dual axis solar tracking system was developed in this work. The tracker is an embedded system that consists of a microcontroller integrated with other components in an electronic circuit to coordinate the activities of the circuit in driving out and in the motor shafts of electrically powered linear actuators used to move the payload. The work is divided into two parts: hardware and software. The hardware part consists of two movable (tilting and axial moving) rectangular frames fixed together and used to hold the payload and two electrically powered linear actuators (jacks) used to move the rectangular frames in the tilting and axial directions. The software part was a code written in the C programming language following an algorithm developed from measured parameters of the jacks and the sun’s position and embedded into a microcontroller. The testing of the dual-axis solar tracker was done by measuring a parabolic trough collector’s position with respect to the sun hour angles and solar declination angles and comparing the values with the calculated angles for two days. The results obtained showed that the tracker followed the sun with deviation of ±2o (percentage errors that ranged between 0.01% and 3.26%).
