Automation of the process is having its own significance with the advancement of science and technology. Human interpretation may influence to produce faulty results. Now-adays the cost of time is also influencing on the schedule of the human being. This paper focused to develop a methodology implemented as prototype working model. Conveyor belt mechanism is introduced to transfer the car from entry point to the work station. IR sensor technology is used to sense the entry level detection of the car to be washed and at the workstation to initiate the washing process. A circular disc mounted to the shaft of the Johnson geared motor used as base to hold the car for washing. The washing process is enabled by using sprinkler and dryer mechanism. A dust particle detection sensor used to trace the dirty surface on any location of the car. The Zero signal from the sensor causes to open the exit level of the car. An RFID-GSM technology is incorporated to dispatch the car for delivery and the washing status completion is informed to the car owner using GSM technology. The results obtained with the proposed methodology enabled to meet the challenges in car washing system.
This paper considered the secured level crossing Signaling system and Train tracking system. This paper adopted a switching logic methodology to meet the challenges of the tracking system. This work also focused to map the train on the display screen. If the train moving close to the level crossing system the signaling system causes to release the green signal that causes to close the rail gate to avoid the unauthorized entry on the rail track. The open state of the gate is influenced by the signaling system by means of a 'Red'colour signal. The train is allowed to move on the track only by considering the green signal. The rail track is organized with four stop positions. Stop 1, stop 2, stop 3 and stop 4. The locations of the train at various stop positions are sensed by using IR sensors. The detected signal is transmitted to the control room using RF transmitter operating at 433 MHZ. An Atmel micro controller is used to regulate the entire process to meet the desired state of the work. This proposed methodology had been successfully implemented on the 30 feet length of the scaled model of the rail track in the laboratory. The system results progressive response while tracking the position of the train. The results are recorded and analyzed. The proposed system may keep alert the monitoring mechanism. So, the collision of the train and unexpected human errors can be minimized.
