Wireless PC Data Logger for Smart Parking System

ABSTRACT

This project is about the new technique for solving parking problems and provide an easy method of parking. In the present scenario, people find it very difficult to park their vehicles in public places like shopping malls etc.

This project considers present parking system issues and provides a solution to develop advanced parking system. This project aims to design a vehicle parking system for the parking lot management. We are using here eight such parking slots.

This enables the car drivers to know the availability of parking space and to park it efficiently and easily with the help of LED Indicator Panel. In this project, we are implementing eight such parking lots. In this application IR transmitter and receivers are used to detect presence or absence of the vehicle. The information is then passed to the microcontroller which is then interfaced with the LED indicator panel to show the status of parking lots. The same information is transmitted to remote end using ZigBee technology. At the receiver, it is received and output is shown in PC terminal software.

A Project on Automatic Lubrication System

Introduction

When lubrication is done on need base and automatically is said to automatic lubrication system. Automatic lubrication is a new concept which Aim’s to improve lubrication process. It is a new step ahead for complete automation of machine tool in industries.

Need

  • In the world, fast growing economy, where mass production is trend machine work for 20-22 hrs human maintenance activity is proved to be very time to consume and insufficient.
  • The quantity lubricant is very difficult to guess for the operator.
  • Improve lubricating and reduce the time required.
  • Insufficient or excessively oiling leads major breakdown reason
  • To eliminate the money spent on maintenance or lubricating personnel.

Construction and Working

The Automatic Lubrication system consists of a sensor, actuator, solenoid valve, battery, reservoir, connecting pipes and the mechanism to be lubricated.

Any rotating or sliding member subjected to friction and wear. This Automatic Lubrication system aims to reduce the friction automatically. A sensor which is capable to sense presence of the lubricant  in the rotating or sliding member is placed close to do so it gives to signal to operate or not, according to the need. Lubricant flow from a reservoir filled with lubricating oil.It aims to keep the optimum quantity of oil in the system.

Advantages

  • No need of human interferences just has to maintain the level of the reservoir.
  • An adequate amount of lubricating oil is supplied hence no chances of excess oiling or insufficient.
  • Reduces the time required to oiling than manual.
  • Increase the quality of performance of the machine and increase the life of the machine.

Application

  • Can be used all types of machines like lathe, milling, drilling, slotting etc.
  • Can be used heavy and fast acting construction types of machinery
  • Can be used in racing cycle.

Conclusion

This is industrial based Automatic Lubrication application project can be of very effectively to improve the performance of a machine.It can indirectly help the society.

Wireless Controlled Digital Score Board Project

Abstract:

Implementation of a digital score board with wireless control is the aim of the project. A digital score board can be used for football, basket ball and volley ball courts.

It consists of Five various display’s. First one for the countdown timer which can be set according to the requirement with a pause and start function. Second and third for the display name of the Team A and Team B, Each display comprises of four alphabet display capability with letter varying from A-Z and 1-9.The fourth and Fifth display are for the respective 2 digit scores of Team A and Team B .

The whole functioning of the digital score board can be controlled with a wireless remote handed over to the referee; The time can be preset in 4 digit timer i.e. with two display’s for minutes and two display’s for seconds, the timer can be paused and started any moment using the remote. The score can be updated by the referee. Score display can be incremented and decremented as per requirements.

The Digital Score board will be powered with AC power supply. It can also be added with a battery backup depending on the requirement.

Model of digital Score Board

Microcontroller based Smart Parking Control System

This Smart Parking Control System project Designed With Microcontroller attempts to cut the time to park the vehicles in the lot and help the motorists to recall the exact parked space. Motorists often spend a significant amount of time to park their vehicles in the parking lots during peak hours. They also may not remember the parked space of their vehicle precisely, while picking up the vehicle.

To solve this problem, an automated vehicle parking system is designed which serves the motorist to find a space for his vehicle within less time. The system displays about the details of freed-up parking spaces. The waiting time to park the vehicle can be reduced by providing this vacant space information to the motorists before he/she enters the system.

The system recognizes the vacant space and displays automatically, this display system can be provided at the entrance of the main gate, so that while entering in to the parking space, the motorist can find his parking place without anybody’s direction.

To sense the vehicle at parking place, infrared sensors are used; the output of the sensors is fed to micro-controller and according to the received information from the sensors, the controller displays, that the particular parking place is vacant or full. For the demonstration purpose three sets of sensors are used to simulate three parking sites.

The system is designed such that, when all parking sites are filled and there is no space for another vehicle, automatically the gate will be closed. To simulate this, stepper motor is used and the controller drives the motor, a small arm of 10″ is coupled to the motor shaft, which simulates either the gate is opened or closed. For displaying the information LCD panel is connected at the output of micro -controller.

Student college simultaneous alert to parent and HOD using GSM, RFID and RF

Aim:  The main objective of this Student college simultaneous alert to parent and HOD project is used to send a message after his son/daughter attended for the college and also the same acknowledge will go to the authority and incrimination of attendance every day.

Description :

This main motto of this Student college simultaneous alert to parent and HOD project is very much longer useful in colleges and also to the parents of the students. The idea behind this project is

1. identification of the student entry at the college in remote LCD display
2. Sending SMS to the parents of their sun/daughter entry at the college
3. Incrimination of the attendance details
4. Showing the student marks on the display by using RFID technology along with their password.

In this Student college simultaneous alert to parent and HOD project we will use 3 ACCESS cards for three students and executes the above points sequentially. The RFID reader which we are going to use for this project uses 125 KHz of frequency. Here in this project we will use total 3 wireless communications 1.GSM , 2. Radio Frequency, and 3. RFID
