Vehicle Accident Alert and Tracking System Project using 8051 Microcontroller

Vehicle Accident Alert and Tracking System Project using 8051 Microcontroller

In the present day, lots of vehicle accidents happen on highways due to the many reasons like an increase in traffic and also due to rash driving of the drivers. And in many situations, the family members of the victim or the ambulance or police authority are not informed in time. This result in delaying the help reached to the person who suffered due to an accident.

So this problem is solved by Vehicle Accident Alert and Tracking System by fitting device into the vehicles. in case suppose the cars meet with an accident then vibration Sensor will detect the accident then Our System gets activated which will track vehicle locations and send the message to the particular number which is predefined in the program. So the person can get help as immediately as soon as possible.

Block diagram:-

Basically, the GPS continuously takes input data from the satellite and stores the latitude and longitude value in AT89S52microcontroller's buffer & show Data on LCD Display.

In this system having a GPS device which is used to tracking the location of vehicle, it also gets deactivated by detecting an accident on the vibration Sensor connected to the vehicle. Parallel activates GSM.

Once System gets activated it takes the last received latitude and longitude positions values and sends a message to the particular mobile number which is predefined in the program in the form of longitude and latitude in the Google map link.

Suppose in some cases the accident is minor so the driver or user don’t want to send an emergency message then he can press the System Switch which sends the signal to the AT89S52 microcontroller will not send any message in case of a minor accident.

But In case of Major Accident Then user or Driver is not in a condition to press any switch so, after 10sec time interval system will automatically send a message with Google map link of Car location.

DTMF Controlled Robotic Vehicle Project

DTMF Based Robotic Vehicle

Previously we have robotic vehicles use RF circuits, which have the drawbacks of limited working range, limited control and limited frequency range. To solve this problem we provides DTMF based robotic vehicle system It provides the advantages of robotic control, intrusion free controllers and also robust control, minimal interference and a large working range.

This system involves four different phases: perception, action, processing and detection. In the perception stage if the mobile attached to the vehicle receives a call, then the pressing key on the mobile decodes the generated DTMF tone. Then, the decoder chip receives the audio signal from the mobile, and then converts the DTMF tone into a binary code, which is then fed to the microcontroller.

Block diagram:

The major building blocks are microcontroller, mobile, DTMF Decoder and DC-Motor-driver circuit. The entire system works and is activated by the mobile that makes a call to the mobile attached to the robotic vehicle. If any button is pressed, then DTMF (dual tone multi frequency) receives the input signal from cell phone and decode it. Then generates 4-bit-digital output of the 8051 microcontroller.

Microcontroller depends upon the code which is generated by the DTMF decoder to move the rover right or left and forward or backward by rotating both DC motors. The DC motor driver receives activating signals from the microcontroller in terms of low or high logic, then it amplifies and rotates two motors in both directions. The output of the microcontroller is not enough to drive the DC motors, so current drivers are necessary for motor rotation.

DTMF Based Load Home Automation Project

DTMF Based Load Home Automation

We know that in industries, loads are distributed over large distances, and it is not convenient to operate all those equipment time to time and it is also time to consume. Into day’s highly developing world most of peoples wants their homes are automated as per increased level of affordability, simplicity and comfort through the integration of home appliances with smart phone and tablet connectivity.

This project we propose DTMF based Home Automation system that provides the wireless controls various home appliances such as a fan, bulb, AC, TV etc. In DTMF based load control system a mobile is connected to the circuit and each key on cell phone correspond to the device that needs to be activated. The key must be authenticating with desire function. The DTMF decoder is used to identify the user choices and appropriate action is performed.

Block diagram:

This project includes DTMF {dual tone multi frequency} tones are composed of a series of low frequencies for each column of keys and a series of high frequencies for each row of keys. Each pressed key creates a signal that is equal to the sum of the column’s low frequency and the row’s high frequencies. When the signal is sent over the telephone line to the telephone company’s switching center, a DTMF decoder separates the signal back into the two frequencies and passes it along to the recipient’s phone. The DTMF decoder is responsible for doing this for all telephone numbers entered by all callers in its designated area every day.

Here, microcontroller is used as a control unit which gets inputs (instructions, commands) from a mobile keypad to control one appliance. Same key will be used to turn on and off the appliance. Each time we press the same key, the appliance changes its status. After the appropriate tone and password is entered, it is decoded via the DTMF decoder which further translates it into binary values this values are the input to the microcontroller which verifies each tone individually and corresponding output is given at the output terminal. Thus, when the relay drive is activated by the microcontroller, the device either gets ON or is switched OFF as per the requirement.
