Abstract

The objective of this paper is to illustrate a method for design and implementation of a room heating system which maintains a constant preset temperature across the given room. Temperature control of room heating system has drawbacks related to repeated ON/OFF switching, longer settling time, large time constants, and overshoot. The temperature of the room may vary over a different range in accordance with the variation in the atmospheric condition. The system is designed with two controllers-GA and PID. GA-PID system has resulted in more percentage saving in power, lower settling time, less overshoots and lower cost in comparison with conventional heater without the facility of wireless dimming. Heater will receive the information about the room temperature and set temperature through remote and constant temperature is maintained by automatic adjustment of control parameters K_P, K_I, K_D using PID tuner and optimization of these parameters with GA. Optimized values has been implemented on real time heater node which comprises of dimmer, processing unit, RF modem and remote control consisting of switch array, RF modem, LCD display, temperature sensor and processing unit. The setup is simulated using Proteus and the control method is simulated using MATLAB. It is observed through experimental set up that the energy saving is upto12.11% as compared to conventional heater. The application will be in household, office premises, shopping complex/malls.

Abstract

High death rates are observed after accidents due to non-wearing helmet of driver with two-wheeler. Many studies on statistics data for various parts of world had been carried out which clearly supports this statement. A new approach to address this issue along with the authentication of ownership of vehicle is proposed, which is designed in such way unless an authorized person with RFID tag wears the helmet the vehicle will not be ignited. The paper focuses on the chip design and implementation of hardware system on FPGA for vehicle. The high speed controller is designed Xilinx 14.2 ISE software with the help of VHDL programming language and synthesized on Virtex-5 FPGA. Modelsim 10.1b is used for the function simulation to test the different test cases. The developed system supports the frequency of 781.250 MHz, which is proposed as optimal solution for the intelligent system.

Abstract

An unmanned aerial vehicle is an aircraft with its crew removed and replaced by a computer system and radio link. This paper describes the use of a multi-rotor unmanned aerial vehicle which includes a system for real time video transfer, temperature sensing and also a smoke detecting unit. The multi-rotor described in this paper is a quad-rotor, which is capable of flying autonomously and transmitting the collected data in real time along with a video feed. The control of multi-rotor is done using graphic user interface, video is received and recorded on a laptop and the data is displayed over another graphic user interface designed on lab-view software. This multi-rotor with the described set of sensory nodes helped in real time monitoring of environment. The use of these unmanned aerial vehicles can be extended to various other fields such as data collection, object delivery, surveillance, research etc.

Abstract

Objectives: This paper provides solution for home automation, in terms of an energy efficient system. The objective is to design a device in the form of an intelligent remote control, to control the ambient condition of a house. Methods: An intelligent RF based remote control is developed which is capable of controlling in two modes- autonomous and semiautonomous. The dimming levels of appliances are tuned with optimized PID controller. A real hardware prototype is developed to control two parameters- light intensity and humidity level of the room. The tuning parameters of PID controller are calculated with the help of overall transfer function of the system, which includes the feedback signal from sensor, objective function of optimization algorithm and transfer function of the appliance (which is used to control the ambient conditions of room). Particle Swarm Optimization algorithm is used to optimize the tuning parameters for PID and results shows more energy efficiency with proposed system, when compared to conventional systems. Findings: The experimental results show prominent saving of energy by using proposed PSO-PID algorithm for designed system. It is calculated as 37.49% for light intensity control system and for humidity control saving comes out 36.9%. Novelty of the proposed system is new approach in terms of intelligent hybrid remote control
