MULTISTORIED CAR PARKING
Introduction:
Automatic multistoried car parking system helps to minimize the car parking area. In the modern world, where parking-space has become a very big problem and in the era of miniaturization, it is becoming a very crucial necessity to avoid the wastage of space in modern, big companies and apartments etc. In places where more than 100 cars need to be parked, this system proves to be useful in reducing wastage of space. This Automatic Car Parking System enables the parking of vehicles, floor after floor and thus reducing the space used. Here any number of cars can be parked according to the requirement. These makes the systems modernized and even a space-saving one. This idea is developed using 8051 Microcontroller. Here program is written according to this idea using 8051.
Aim of the project:
To implement a prototype system, this is meant for parking number of vehicles in a multi-stored building. This design is based on 8051 microcontroller which plays a major role in the area of Embedded Systems. Embedded System is a combination of H/W & S/W, which has specific requirements and performs pre-defined tasks. It is expected to function with minimal human intervention. It is a time-constrained and often resource-constrained. It can be existed from aerospace to earth.
Embedded Systems characteristics are,
1) Single function.
2) High performance.
3) Safety.
4) Size.
5) Real time oriented.
6) Operated at harsh environments.
7) Easy handling.
OVERVIEW OF CAR PARKING SYSTEM
CRITERIA FOR CHOOSING 8051 MICROCONTROLLER:
The criteria for choosing a Microcontroller.
1) It should meet the task at hand efficiently and cost efficiently. We must 1st see whether an 8bit, 16bit or 32bit can handle our project task. For this we have to consider its speed, packaging i.e., if it is a DIP(dual in line) or QFP(quad flat package) or some other, power consumption, amount of on chip ROM & RAM, number of I/O pins & timer on chip, cost per unit(i.e., total kit cost).
2) Availability of software development tools such as assembler, debugger, compiler, emulator and technical support to the Microcontroller both on in-side and out-side expertise.
3) Wide availability of Microcontroller which fulfill needed quantities or sources of both now and in future.
In case of 8051, in leading 8-bit Microcontrollers it satisfies all the above mentioned criteria as there are multiple suppliers with same code compatible.
AT89C51 Series:
The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers (µCs) manufactured by the Atmel Corporation.
Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, and low unit cost. This allows a great amount of legacy code to reuse without modification in new applications. While considerably less powerful than the newer AT90 series of AVR RISC microcontrollers, new product development has continued with the AT89 series for the aforementioned advantages.
Of more recent times, the AT89 series has been augmented with 8051-cored special function microcontrollers, specifically in the areas of USB, I²C, SPI and CAN bus controllers, MP3 decoders and hardware PWM.
It is a programmable IC. Here we are using one of the version of 8051 microcontroller i.e., AT89C51 which is Flash Programmable IC. AT represents the Atmel Corporation, C represents CMOS technology is used for designing the IC. This IC is programmed in EmbC language.
