Car Parking Guard Circuit Using Infrared Sensor

While parking the car the driver should be more careful because he cannot see the back of the car while parking or taking reverse, if there is any obstacle and ran over it might be get damage to the car. Our project will help the person in the driving seat and give alarm if there is any obstacle or a wall while parking or while driving in reverse.

Block Diagram of Car Parking Guard:

The IR sensor will detect the obstacle with in 100cm, if there is any obstacle it will sense and give information to the tone detector which will enable the LM555 timer to generate a PWM for the buzzer. The LM555 will generate the pulse which helps to buzz the buzzer so driver can understand that there is an obstacle.

Main Component Explanation:

LM567: is a tone detector which can interpret the frequency generated by the other component and give the output according to the application designed by the engineer. For example if a component is attached to the input of LM567 which can generate a 40 kHz signal , but we to function the following circuit when the component has reached to the 40KHz. At this decision making we will use tone detector. The tone detector is mainly used in touch tone decoders, ultrasonic controls, frequency monitoring and control etc.

LM555: is a timer which can generate a PWM signals in various width and duty cycles. The 555 timer is mainly used to control the other peripherals like motors, detectors, regulators etc.

IR Sensor: the main function of the IR sensor is to produce a beam for certain distance (the distance of the beam is always depends on the IR sensor, different IR sensor have different range of beam distance) if the there is any obstacle in the beam it will conduct and give signal.

Photo Darlington Transistor: the photo darlington transistor will act as a photo detectors. They will conduct to the light or electro magnetic signals. The main function of this transistor is to amplify the input signal of the transistor. But it will work slowly when compared to the other transistors. It is having a maximum frequency of 20 KHz.

You are to modify the Car Park Guard Circuit of Figure 1 by including two more IR LED3 and IR LED4 detectors, which will detect obstacles at the left and right rear of the car.

- If an obstacle reached and the warning alarm should stay ON until the obstacle is far enough for it to stop.

Any changes to an installation must be documented. It is always a good idea to record the original connections or circuit design so that you could retreat to that point if things don't work out the way you expected. Recording simple things such as time delay settings and switch positions, for example, could save you considerable time when commissioning the circuits.

Safety is of paramount importance. You should never take short cuts when testing. It is sometimes very tempting to operate equipment with safety guards removed or limits bridged out during the initial testing phase of the new design. You should have a very good reason to operate any equipment with part of the safety controls disabled.

Your project consists of three assessment events:

1. Electronics and Communications Engineering specifications encompassing
2. Dealing with suppliers and manufacturer's encompassing
3. Research skills encompassing Should also include:

- Establishing the scope and parameters of the projects
- Determine the impact of other related works.
- Developing design brief incorporating scenarios and all requirements.
