Abstract:
Automatic parking system is a very good substitute for parking area management. Since in the modern world, where space has become a very large problem and in the age of miniaturization has become a very crucial need to avoid wastage of space in modern, large companies and apartments, etc. In The space where more than 100 cars should be Parked, it is a very difficult task to do and also to reduce the waste of area, this system can be used. This automatic parking allows the parking of vehicles-floor after floor and thus reduce the space used. Here any number of cars can be park according to requirement. This makes the systems modernize and even save space. Automatic parking system here we work on the idea of showing the parking number available on the parking site. In this when you at the parking site, you see the number of parking slots and available parking slots at the entrance door. If parking is available, the door is open for a few seconds and that particular slot is marked unavailable. When leaving this same process is followed and particular slot is made available to the next customer.
Functional description:
This project can be implemented using the following blocks. To facilitate the understanding of the blocks are mentioned below:
Proximity sensors: These are placed inside the parking slot to detect the presence of the vehicle in the slot, which will be used to process when a new vehicle requests parking slot which also consists of IR diodes and phototransistors.
IR Light Emitter: It consists of a pair of red IR lights that continuously emit long directed IR lights. This light falls on a pair of LDRs.
IR Light Receiver: Consists of a pair of LDR (Light Dependent Resistance). The LDR consists of special materials whose resistance depends on the amount of light that falls on it. This means that while the IR light falls on it its resistance is low almost 1k. As soon as this light is obstructed, the resistance of these sensors increases (up to almost 8k) indicating the presence of something between the emitter receiver pair.
Comparator block: It consists of a comparator circuit made of op-amp LM358. Its task is to convert the state of resistance of LDR into the state of tension understood by the microcontroller.
Microcontroller Block: The microcontroller takes the data from the comparator block. Based on these data interprets the number of people who have crossed from one side to the other and vice versa. To build this system we are going to use 8051 variant.
Display unit: It is 16 * 2 LCD that shows the number of people in the room at any particular time. It also shows which device is being used and how much power is being used.
Appliance Block: This block consists of DC motor outlets. The DC motor is powered in a specific direction for 10 sec. And then ON in the opposite direction for the same time interval of 10 seconds to open and close the gate.
Power Supply Block: This consists of a downstream transformer that converts 220V AC to 15V AC.
