Description of the project:

Nowadays in many multiplex systems, there is a severe problem for car parking systems. There are many lanes for car parking, so to park a car one has to look for all the lanes. Moreover, there is a lot of men labor involved in this process for which there is a lot of investment. So the need is to develop a system which indicates directly which parking slot is vacant in any lane. The project involves a system including an infrared transmitter and receiver in every lane and an LED & LCD display outside the car parking gate. So the person entering the parking area can view the LED display and can decide which lane to enter so as to park the car.

Conventionally, car parking systems do not have any intelligent monitoring system. Parking lots are monitored by human beings. All vehicles enter into the parking and waste time searching for a parking slot. Sometimes it creates a blockage. The condition becomes worse when there are multiple parking lanes and each lane has multiple parking slots. The use of automated systems for car parking monitoring will reduce human efforts. The display unit is installed on the entrance of the parking lot which will show LEDs for all Parking slots and for all parking lanes. An empty slot is indicated by the respective glowing LED.

Description in detail:

We are going to use Infra-Red transmitters and Receivers for each parking slot. The IR Receivers are connected to 8051 microcontrollers. IR rays are obstructed when a car is parked in any parking slot. Thus AVR will come to know which slot is empty and which slot is full.

We have chosen the IR module instead of an RF module because we want a receiver having a line of sight communication with the transmitter. But RF does not require line of sight communication. And in the case of LDR, there is scope for false triggering due to sunlight or headlight of a car. So considering all these points we have finalized to use the IR module.

For the transmitter section, we are going to use IR LEDs driven by a 555 timer IC. Timer IC will generate a frequency of 38 kHz, which will be given to IR LEDs.

Applications, Advantages and future development of the project:

1. This project can be used for the parking system in any shopping mall, multiplex
2. It can be used for industries, commercial offices, and educational institutes.
3. This can be expanded in the sense of security. Using metal detectors and CCTV cameras security of the parking area can be enhanced.
4. We can add the Pick and Place facility to park the cars automatically.

Question and answers about this project:

Question: What is the maximum number of parking slots that can be connected to this project?

Answer: This depends on the number of pins of the microcontroller. We can connect 16 slots to the microcontroller. 89s51 microcontroller has a total of 32 pins, out of which 11 are required for LCD. For LED display we can 4:16 decoder, so it will need 4 pins and then we can connect 16 slots to the remaining pins of the microcontroller

Question: Do you have an automated parking lot with a robotic arm added to it to place the car into the available parking slots?

Answer: That's a kind of Electro-Mechanical project. Sorry, we don't have a pick and place facility for car parking.

Question: Can we use this project for multiple level parking like using Elevator or something like that?

Answer: We can place the 2 slots on the ground floor and 2 slots on the first floor. However, we can not implement the elevator section.
