Thus it came to our notice that theft the vehicles and reduce malpractice on the number plates road accidents especially in India are increasing at a faster rate. This lead us to think about the various causes of road accidents. We find out a number of reasons including driving while drunk, over speed, improper traffic controls, disobedience of traffic rules, substandard roads, mental stress, carelessness and usage of mobile phone while driving. that times number plates are identified is main thing. When we consider each of the above cases separately, for example over speed, there are already existing preventive measures to detect speed of vehicles. Likewise in the case of remaining factors also there are preventive measures or awareness can be done to an extent. But in the case of usage of mobile phone while driving, even though it is against law, there is a tendency among people to fake number plate. A brief comparison of the functional architecture of the microprocessor and microcontroller are explained below. The basic components of the microprocessor are CPU and external interface. The CPU consists of Arithmetic and Logic Unit and the instruction execution and decoding unit. In addition memory management, floating-point arithmetic instruction and data cache are also incorporated. External co-processor interface is provided for floating point arethmatic operation. The microcontroller is an I/O oriented single chip microcontroller. It is a subset of microcomputer with ALU, input, output, and memory and control unit. The microcontroller normally consist of CPU, internal RAM, internal EEPROM ,main memory, I/O port, DMA controller, interrupt handlers, timers, watchdog timers, ADC and DAC. Microcontrollers are widely used in control applications since the on-chip peripheral provided on them makes the system design simple and economical. The instruction set of microcontroller is versatile and suited for control applications. Thus it came to our notice that theft of the vehicles and reduce malpractice on the number plates road accidents especially in India are increasing at a faster rate.
