Here in this paper we have proposed to control the traffic issue presently observed in cities dealing large population and inadequate infrastructure. Now a days road safety enforcement and traffic regulation is very difficult. To overcome this problem the interface is designed in this paper is cost effective, efficient and easy to implement on already existing vehicles. Consider a city or town, which is divided into physical zones, which are classified according to different speed ranges. A transmitter is placed at all exit and entry points of the interface of zones that transmits a message signal at carrier frequency, indicating the upper limit value of the zone speed range into which the vehicle is entering at that moment. The receiver, which gives the message as an input to a preprogrammed microcontroller, embedded within the automobile, which compares the speed of the vehicle measured by a sensor at the maximum allowable speed and automatically regulates the speed of the vehicle. The speed of the vehicle can be varied by varying the “duty cycle” of the pulse input. The entire system is a low cost variable electronic speed governor, small and easy to assemble onto an existing vehicle without disturbing its present arrangement. Keywords: Zones, Microcontroller, transmitter, receiver, speed. by using a suitable capacitive filter. The constant voltage is provided using a voltage regulator 7805 for +5V and 7812 for +12V. II.

INTRODUCTION In this paper, we are concerned of providing a Tracking and breaking system for vehicles with the help of some obstacle detecting sensors used to detect the vehicle. It detects the vehicle when it enters the zone and automatically controls the speed of the vehicle. This paper consists of two sections. The transmitter section consists of an IR sensor, a motor a micro controller and a RF encoder, RF transmitter module. IR sensor, which is used for detecting the vehicle. If any vehicle enters the zone, IR sensors present at the zone section detects the vehicle and controls the speed until it leaves the zone. This system can be implemented on an already existing vehicle. Present paper is designed using AT89S52 microcontroller to develop an anti-theft system for museums and jewelry shops [1]. The incoming 230V A.C (Alternate Current). power is step down to 12V using a transformer. The A.C power is converted into pulsating dc using a bridge rectifier. The pulsating components or ripples are removed FIG1:BLOCK DIAGRAM OF ZONE SECTION B.VEHICLE SECTION The vehicle section is described in figure2and Figure3. ISSN: 2231-5381 http://www.internationaljournalssrg.org Page 430 International Journal of Engineering Trends and Technology- Volume4Issue3- 2013 Microcontroller is a microprocessor designed especially for controlled applications and is equipped with ROM, RAM and I/O on a single chip. Encoder simply HT12E Converts parallel inputs in to Serial outputs. It encodes 12-Bit parallel data in to serial for transmission through RF transmitter. These 12-bits are divided in to 8 address bits and 4 data bits. LCD Display LCD Modules can present textual information to user. It’s like a cheap “monitor” that you can hook in all of your gadgets. They come in various types [3]. The most popular one is 16x2 LCD Module. It has 2 rows and 16 columns. RF Transmitter The RF module, as the name suggests, operates at Radio Frequency. The corresponding frequency range varies between 30 kHz & 300 GHz. infrared light of the transmitter strikes the object to be detected and is reflected in a diffuse way. Part of the reflected light strikes the receiver and starts the switching operation. FIG3 : IC- PIN DIAGRAM FIG2: B LOCK DIAGRAM OF VEHICLE SECTION Power Supply: This paper uses regulated 5V, operating frequency 11.09MHz,500mA powersupply,7805 three terminal voltage regulator is used for voltage regulation. IR Transmitter And Receiver: Infrared (IR) radiation is part of the electromagnetic spectrum.IR wavelengths are usually expressed in microns, with the lR spectrum extending from 0.7 to 1000microns. Transmitter and receiver are incorporated in a single housing. The modulated infrared light of the transmitter strikes the object to be detected and is reflected in a diffuse way. Part of the reflected light strikes the receiver and starts the switching operation RF Receiver: Transmitter and receiver are incorporated in a single housing. The modulated Decoder: In simple terms, HT12D converts the serial input into parallel outputs. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins Motor Driver: A system consists of elector motor and accessory parts, used to power supply . In this case we use 12 V range. Pin Diagram: The AT89S52 is a 40 pin IC with Dual In line package. There are 4 ports P0,P1,P2 and P3 with 32 I/O Pin as shown in the figure 3. Pin description: - VCC: Supply voltage, GND: Ground. Port 0 is an 8-bit open-drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When one’s are written to port 0 pins, the pins can be used as high impedance inputs. Port 0 may also be configured to be the multiplexed low order address/data bus during accesses to external program and data memory. In this mode P0 has internal pullups. Port 0 also receives the code bytes during Flash programming, and outputs the code bytes during program verification. External pull-ups are required during program verification [2]. Port 1 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 1 output buffers can sink/source four TTL inputs. When 1s are written to Port 1 pins they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups. Port 1 also receives ISSN: 2231-5381 http://www.internationaljournalssrg.org Page 431 International Journal of Engineering Trends and Technology- Volume4Issue3- 2013 the low-order address bytes programming and verification. during Flash Port 2 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 2 output buffers can sink/source four TTL inputs. When 1s are written to Port 2 pins they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memories that use 16-bit addresses (MOVX @DPTR). In this application, it uses strong internal pull-ups when emitting 1s. During accesses to external data memories that use 8-bit addresses (MOVX @ RI), Port 2 emits the contents of the P2 Special Function Register. Port 2 also receives the high-order address bits and some control signals during Flash programming and verification. Port 3 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 3 output buffers can sink/source four TTL inputs. When 1s are written to Port 3 pins they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current (IIL) because of the pull-ups. For example a 5V regulated power supply system is shown in the figure 4. The transformer shown in the figure5 is an electrical device which is used to convert electrical power from one Electrical circuit to another without change in frequency. Transformers convert AC electricity from one voltage to another with little loss of power. Transformers work only with AC and this is one of the reasons why mains electricity is AC. Step-up transformers increase in output voltage, step-down transformers decrease in output voltage. Most power supplies use a step-down transformer to reduce the dangerously high mains voltage to a safer low voltage. The input coil is called the primary and the output coil is called the secondary. FIG 5: ELECTRICAL TRANSFORMER Rectifier: As shown in figure 6 a circuit which is used to convert a.c to dc is known as Rectifier. The process of conversion a.c to d.c is called “rectification” FIG 4 :COMPONENTS OF A TYPICAL POWER SUPPLY The power supplies are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronic circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function. A d.c power supply which maintains the output voltage constant irrespective of a.c mains fluctuations or load variations is known as “Regulated D.C Power Supply” FIG 6: RECTIFIER Filter: A Filter is a device which removes the a.c component of rectifier output but allows the d.c component to reach the load. Regulator: Voltage regulator, shown in the figure 6. ICs is available with fixed (typically 5, 12 and 15V) or variable output voltages. The maximum current they can pass also rates them. Negative voltage regulators are available, mainly for use in dual supplies [4]. Most regulators include some automatic ISSN: 2231-5381 http://www.internationaljournalssrg.org Page 432 International Journal of Engineering Trends and Technology- Volume4Issue3- 2013 protection from excessive current ('overload protection') and overheating ('thermal protection'). Many of the fixed voltage regulator ICs have 3 leads and look like power transistors, such as the 7805 +5V 1A regulator shown on the right. The LM7805 is simple to use. You simply connect the positive lead of your unregulated DC power supply (anything from 9VDC to 24VDC) to the Input pin, connect the negative lead to the Common pin and then when you turn on the power, you get a 5 volt supply from the output pin, shown in figure 7. FIG7: A THREE TERMINAL VOLTAGE REGULATOR III. IMPLEMENTATION The design tools and programming software used for the implementation are as follows. -Design tool – Proteus -Software programmer – Keil software The program is written in the embedded c language. It is stored in the internal memory of the microcontroller. The KEIL compiler is used for the execution of the program. It will be tested on proteus software by dumping program into microcontroller. The steps included in this are This paper is mainly concerned with tracking the zone and breaking the vehicle speed with the help of microcontroller, IR sensor, lcd display, RF transmitter and receiver. It deals with two sections. One is zone section and the other one is vehicle section [4]. To employee this system we have to place a vehicle section inside the vehicle. This should be done during manufacturing of vehicle. However this can be implemented on an already existing vehicles. The IR transmitter detects the vehicle when entered and stops transmissions to receiver which indicates that the vehicle has been detected. Thus limits speed of that vehicle to fixed range. when the vehicle leaves the zone it automatically gains its previous speed. The lcd display at the transmitter section are employed to display the mode in which it operates. Algorithm for Zone Section Step 1: Assign the header files reg51.h and lcd.h Step 2: The single bits are assigned to the ports by the IR sensors. Step 3: The LCD commands are assigned for displaying purpose and a delay is 1000ms is assigned. Step 4: The conditions are verified by using while statements as if(ir1==0 && ir2==1 && ir3==1 && ir4==1). If the statement is true then LCD displays zone1 entered. Step 5: Similarly the while conditions are verified as else if(ir1==1 && ir2==0 && ir3==1 && ir4==1 &&\ f1==0) LCD displays as zone1 exit else if(ir1==1 && ir2==1 && ir3==0 && ir4==1) LCD displays as zone2 entered else if(ir1==1 && ir2==1 && ir3==1 && ir4==0 && f2==0) LCD displays as zone2 exit. else if(ir1==1 && ir2==1 && ir3==1 && ir4==1 && f1==1&&f2==1)LCD. displays as normal mode.

B. Testing The components power supply, microcontroller, IR sensor, lcd display, RF transmitter and receiver, door control system and switch are placed on a PCB and the connection are made as per the circuit diagram. Now if we place the vehicle between IR sensors it detects the vehicle presence and sends data to the microcontroller. The microcontroller sends the data to the RF encoder, it then encodes the message and transmits through the RF transmitter to the receiver section [5]. The RF receiver receives the information through RF communication, then decodes the message using the RF decoder and then gives it to the microcontroller. It then send the data to vehicle section and lcd display. C. Result of Implementation Whenever we place the vehicle before the IR sensor, it detects the vehicle presence and sends the data to the microcontroller, which in turn sends it to the RF encoder. The RF encoder encodes the message and sends it to the RF transmitter. The RF receiver receives the data through RF communication, then it decodes the message and sends it to the microcontroller. The microcontroller passes it to the vehicle section and the lcd display. Finally the vehicle section and lcd display responds to the message transmitted to them and limits speed [6]. #3. P.
