ONLINE MONITORING OF SOLAR BASED STREET LIGHT AND GPRS BASED FAULT AUTOMATIC FAULT INTIMATION

project center in Tirunelveli 

Badly lit roads lead to vehicle accidents and encourage crime. Therefore, it is important to rapidly detect and report faulty streetlights (FSLs) to the relevant authorities to keep roads safe. Currently, communities primarily depend on electrical inspectors to check streetlights regularly, which may result in long and unnecessary delays prior to repair. Recent studies have focused on adding a networking capability (i.e., a wireless sensor network) into street light poles to enable real-time status reports. However, a smart system that would incorporate sensors and network modules into every streetlight would be expensive; therefore, it would be nearly impossible to realize this system quickly. In this project, we propose a noninvasive method for detecting faults on the solar based street lights that involves with the collection of information about streetlights’ intensity. The collected data would be used to intimate the authorized person in the corporation about the fault. The GPS system in our module can recognize the exact position and also send sms through GPRS facility on it. This effective system can intimate the fault occurred on the particular solar power street light without fail. This system is not required any manual checking or else any manual intimation during the fault occasions. The embedded controller will be a brain of this system that will coordinates all the operations such as fault detection, GPS and GPRS activities.

project center in Tirunelveli 

GSM based LPG weight and LPG leakage detection system has application in Home, Hotels, Restaurants, as well as in industries. This Project is used to monitor the weight of LPG gas cylinder. In our home we observe whenever LPG gas cylinder is empty. We give request for new cylinder at the office of gas cylinder provider. Many times it happens that because of the Rush or due to the shortage of cylinder, there is a delay in providing the gas cylinder. Main reason behind this is delay in informing to the gas provider or we inform the gas provider at the last moment when the gas is empty. One more example in hotels or sometimes in industry also the LPG gas is also used. In home or in hotels the main purpose of LPG gas is for cooking. But in the industry sometimes, LPG gas or some other combustible gas is used for some other purposes like welding or cutting or for some other use. In these places if the LPG gas inside gas cylinder was finished at that time request for new gas cylinder is sent to the storage department but if there is shortage in stock then there is delay in providing new gas cylinder. To avoid all such situations, we have implemented a project called SMS based LPG gas weight detection system using GSM technology with gas leakage detection also.

Wireless internet and cellular mobile services are essential part of our life infect modern world fully relies on wireless communication. Due to increase of users all around the world and rapid developments in different wireless technologies we may face crisis in future because continues increases in demand of data transmission could not be full fill in future keeping in mind the lack of radio frequency bandwidth . This project aims to demonstrate that Li-Fi which is an emerging branch of optical wireless communication can provide us matured solution of this fundamental problem. Professor Harald Haas who is recognized worldwide as a creator of Li-Fi technology gives his concept of transmission of data with the help of illumination .This procedure consists of sending bundles of information through visible light spectrum via LED light bulb .Now a day’s Wi-Fi (Wireless Fidelity) is most commonly use for Wireless indoor communication, which require 2.4 - 5 GHz Radio Frequency to deliver wireless Internet access around our homes, schools, offices and in public places. Li-Fi by using visible light as transmission medium can provide us faster, efficient and secure communication as compare to Wi-Fi with high capacity as its spectrum Bandwidth is much broader than the Frequency of Radio spectrum.

GPS BASED BLIND NAVIGATION SYSTEM FOR INDOOR

project center in Tirunelveli 

Objective of this project is helping the blind/old persons travelling easy and illiterate people as well as pedestrian people using an interactive embedded Wireless Sensor Networks. The term blindness refers to the people who have no vision at all or people who have less vision. Most of the blind people take support from guide dogs to walk. We are explaining about the GPS and voice navigation system for blind people.

In this blind people issues the commands and then receive the response using audio signals. GPS receiver is used to receive the values of the latitude and longitude continuously. With the advancement in technology usage of voice recognition is easier to send commands regarding directions to the blind people. As an application of this GPS technology here GPS based voice alert system for the blind persons are very useful, compact and simple system to handle. Today the increase in traffic cause pedestrian to the road harder. The thing is worse if a blind need to cross the road. There are many technologies developing rapidly, but for physically challenged there is not greater development. This project is developed to make the blinds cross the road safely. It consists of a micro controller and Voice controller to show the status of the signal through voice and GPS. This project is very useful for blind people in order to find the traffic signal during their travel. By using this project blind people can walk without human help.

FLIGHT COLLISION AVOIDANCE USING GPS BASED INTELLIGENT BEACON SYSTEM

project center in Tirunelveli 

Collision in Aviation is an unexpected accident in which two or more flights come into unplanned contact during flight. Owing to the relatively high velocities involved and the likelihood of subsequent impact with the ground or sea, very severe damage or the total destruction of at least one of the aircraft involved usually results. The potential for these collisions is increased by deviations from flight paths and the lack of collision-avoidance systems. Although a rare occurrence in general due to the vastness of open space available, collisions often happen near or at airports due to communication towers or any ancient tall buildings. The project is proposing a collision avoidance system for the aviation system. The Global position system (GPS) is responsible to locate the longitude and latitude of the accident zones like communication tower or tall buildings nearby. The embedded controller is casting as a brain for the proposed beacon system inside the flight. The beacon system can intimate the pilot while crossing the dangerous zone. The system also able to recognize the flight-to-flight collision with the help of sensors array fixed on the each flight body. This arrangement can alert the beacon system if there are any symptoms detected for collision. This intelligent beacon system is alerting the pilot by means of voice or alarm.  Thus the proposed collision avoidance is profitable vigilant system for avoiding the unnecessary flight collisions. 

VISION BASD RESCUE METHOD BY USING RCR ROBOT

project center in Tirunelveli 

Children often fall down in the bore well which have been left uncovered and get trapped. The rescuing of this trapped child is not only difficult but also risky. A small delay in the rescue can cost the child his or her life. To lift the child out the narrow confines of the bore wells is also not very easy. The child who has suffered the trauma of the fall and is confined to a small area where, with a passage of time the supply of oxygen is also reduces. This project genesis a robotic based child recuing in particular for the latter accidents. Robots can only offer a solution for bore well rescue because it is fast, Economical and safe. Moreover, it has the facility to monitor the trapped child and provide a supporting platform to lift up the child. Borehole robot consists of 3 wheels with rubber grip for which motors are connected and these wheels have spring suspension also. So that, the wheels will exact fit to the walls of the hole which make the robot to travel down without any sliding and also this robot consists an arm which is used to pick up the child from the borehole. This aids to recover the child from the bore well without any danger of the victim. The sensor systems are interfaced with the brain of the robot called “Arduino”. A camera along with an LED light is used to visualize the victim as well as it helps to operate the system by control unit. The robot Hand movement is used to adjust the child position while lifting. The arm movement of the robot is controlled by DC motor. Once child is perfectly picked by robot, DC motor is used to lift up the child from borewell. The ZigBee plays a vital role of data transferring between the victim in borewell and the recovery team in earth surface with monitor.

project center in Tirunelveli 

In a power system network the overhead lines are playing the vital roles to transmit the power to the consumers and also it should treated very precisely. Because the serious damages on these overhead lines may create the voltage, current surges and moreover it may spread the arc waves through the lines. These disturbances may travel into other healthy feeders as well as connected load.This project is proposing a novel inspection and control embedded system for the overhead power lines. This project is individually monitoring the voltage, current, temperature and humidity of the transmission line of concern. The above mentionedparameters are the key factors for the transmission line faults (either short circuit (or) insulation failure) so the proposed system is closely monitoring the above parameters. If there any violation in these parameters, the system immediately response to open the particular unhealthy line and also alerting the wireman through sms. Thus the proposed system is fully utilizing the embedded system as well as GSM communication protocol to safeguard the whole power system network from the serious accident.
