Radio Frequency Identification (RFID) is one of the automatic identification and non line of site technology. In this technology communication is in between the tag and reader. The tag is movable object like a smart card and any type of material object. Each tag have magnetic strip with the specific code and tag is read by RFID reader module. One RFID reader module is simultaneously communicate with the number of tag but one tag is not communicate with the number of RFID reader module. In this project provide the car parking area security with the help of RFID technique. When user show his RFID tag to the RFID reader. Reader read the code information which available on the tag and with the help of microcontroller program memory, display required comment on LCD. If the code is match then open the door of parking and if code is reject by the reader then closed door of parking as well as buzzer ON. In the project, alcohol detection system also required for the safety of human and cars in parking area. Alcohol sensor MQ-3 is gas sensor which is more sensitive about alcohol and lower conducting in atmospheric clean air.
Leakage current monitoring associated with the method for measuring the pollution levels on High Voltage insulator of overhead transmission line. This paper describes the various pollution monitoring techniques of High Voltage insulator such as frequency characterization, patternrecognition, optical detection of partial discharge, sensor system with satellite communication link etc. By using the combinations of sensors, processing techniques & electronics set up, the characteristics of the leakage current can be evaluated. Frequency characterization investigated with artificial contamination tests & field tests. Pattern recognition technique classifies the state of insulation structure in online application. The system comprises a fiber-optic sensor, directly connected to one insulator of the string that emits a sample of the leakage current waveform to a processing module via an optical link. Satellite based monitoring along with the Important results were achieved during the field implantation, mainly related to system design & features that need to be applied during the building of tower with transmission line of High Voltage. Experimental activities & field system records the relevant status of pollution level.
Phase, frequency, and amplitude of phase voltages are the most important and basic parameters need to be controlled or grid-connected applications. The aim of this paper is to present a review of various synchronization techniques for pulse width modulated voltage source inverter. This paper describes the estimation method and verifies its usefulness by extensive numerical experiments. Various synchronization algorithms are described here. The primary application of the proposed synchronization methods is for the distributed generation units with renewable energy sources, which utilize power electronic converters as an integral part of their systems. The synchronization is usually carried out with respect to the voltage, frequency and phase angle of voltage (or current) signal(s) of the utility system. The paper also describes the issues, challenges & solutions for.
