RF ID BASED CHILD KIDNAP PROTECTION

project center in Tirunelveli 

Child kidnap or abduction is the unlawful taking away or transportation of a child against that child's will, usually to hold them unlawfully. This may be done for ransom or in furtherance of another crime. The most child abductions are executed during those who returning from school to home. The school van may lost a child without correctly knowing about his/her target place. Especially a new van driver does not know each child’s step off location. The child may feel sleepy when his/her step off location crosses. These instants are leading to child abduction and the main reason for this kind of unlawful activities is not having the adequate knowledge about the current location. This project proposes a novel child kidnap protection system with the help of RF ID tag arrangement and GPS facilitated school van. In this novel technique, the child can hold & swipe RF ID tag on the school van while he/she hires the school van. After swiping the tag, the stored database information about the child’s residential address and its landmarks can be retrieved. While the school van starts, the GPS system starts recording the position of the school van and also alerting the location of school van to the each parent as a SMS. By the way of doing this alert, the parents can vigilantly note down the current location of the school van. The embedded system inside the van can display the name of the child with an alarm while the van reach the child’s step off location. This will help the new driver to alert the child without fail. The proposed system is a real time application based on RF ID, GPS and embedded system technology and this reliable system can avoid the child abduction effectively.

ACCIDENT PREVENTION IN BLIND CURVE USING ZIGBEE PROTOCOL

project center in Tirunelveli 

As the number of vehicle in transportation system are widely increasing; so it has been a major concern for highway authorities to facilitate effective control of traffic for collision avoidance. For various highways, these rising demands cannot be counteracted by further extending the existing road infrastructure giving a special importance to the efficient use of the existing network. In this aspect, this project proposes a novel approach for alerting the vehicle during blind curve spot. This system mainly depends upon the piezo electric sensor arrangements on both side of the blind curve road and along with the danger light system with display units. Depending upon the pressure applied on one side the danger light (red light) is activated on the other side and also display unit also intimating with the string “STOP & WAIT”. The aforementioned operation can be applicable to either side of the blind curve road.This advanced & automated system is boon for the transportation system that can lead to human safety on the critical scenarios.

DEVELOPMENT OF A BLOOD LEAKAGE MONITORING SYSTEM FOR THE APPLICATIONS IN HEMODIALYSIS THERAPY

project center in Tirunelveli 

A commercial blood leakage detector, specific for hemodialysis therapy is currently available, which requires the sensing sensitivity of less than 1 ml of blood, and the blood leaking condition can be detected in 1 ∼ 2 seconds. The sensing method is basically based on the changes of the voltage signal in the sensor.  The main aim of our project is to inform the doctor about the patient conditions through voice and wireless communication. In this project Bio- system parameters namely heart beat, patient temperature and presence of the blood leakage. Abnormality in any one of the parameters will be send voice message to hospital staff and monitor through doctor.

                               Bio technique is that biomedical signal transfer a link between the patient and the physician. By using a miniature transmitter attached to the patient to inform over a range. The physician study and resets the subject with his full mobility. This technique provides the best method of isolating the patient from the recording equipments. 

 Heart beat is sensed by the electronic sensor unit. It gives current outputs directly proportional to absolute pulse variations. This is amplified using Instrumentation amplifiers and feed to embedded controller. The embedded controller wills continuously receiving these signals through sensor circuits and further do the work of displaying and inform to doctor through wireless communication. Temperature is sensed by the LM35. It gives current outputs directly proportional to absolute temperature variations. This is amplified using Instrumentation amplifiers and feed to ADC. The blood leakage can be sensed by Opto sensor. It is fixed at an appropriate location Presence and absence of blood variations of opto sensor. Above mentioned sensing circuits are connected to embedded through interface card. It will continuously receiving these signals through sensor circuits and further implement the communications. The RF transceiver is used continues monitoring of patient condition through wireless connectivity. As a primary function, the proposed work is successfully implementing blood leakage detection where if the blood leakage is detected, then the vacuum pump is suck the blood. And the voice processor is informing the patient condition to the hospital staffs.   

AN ANDROID APPLICATION BASED EMERGENCY OVERHEAD LINE DEACTIVATING SYSTEM FOR THE PROTECTION OF POWER SYSTEM COMPONENTS

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 mentioned parameters 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 alerting the control room. The control room technician may use the android application to on/off the circuit breaker. The control signal is recognized and then transmitted through the wireless communication. The circuit breaker on the field is responsible to trip off the concern line. Thus the proposed system is fully utilizing the embedded system as well as wireless communication protocol to safeguard the whole power system network from the serious accident. This system is dipping the man effort by means of android application interface.

Vehicle Safety features are designed to avoid collisions and accidents by offering technologies that alert the driver to potential problems. This project is addressing an advanced vehicle assistant system (AVAS) by integrating RADAR, IR sensor units and GPS location finder applications. The main aim of this project is to assess the driver by intimating the left and right side postures of the vehicle and also alerting the driver during critical touching to the vehicle before to it. This proposed technique implemented with RADAR system that continuously transmitting a low frequency signal and according to the RADAR principle it is easy to find out the distance between the RADAR source to the obstacle. So the same principle is applied here to intimate the driver when the vehicle exceeds the predefined threshold distance between the vehicle and the vehicle before to it. The system also handling the left & right side posture monitoring in order to avoid the collisions and this is designed with the two IR sensors on the two sides. This proposed system is locating the accident spot with the help of GPS location finder and sending the location information to predefined person ie. May be a family member, as an urgent.
