Speed Checker On Highways

Speed checker For HighwaysAbstractAim of this project is to develop a device to detect rash driving on highways and to alert the traffic authorities in case of any speed violation.ComponentsMicrocontroller 8051 is the heart of this project.There are many more important part of this project:A pair of IR sensorsSeven Segment DisplayBuzzerMicrocontrollerIn this project, main work of 8051 is to control entire operation through a coding which is burned inside it manually.

IR SensorsIt simply sense the vehicles and inform the controller, 8051 complete rest of the work.

Seven Segment DisplayIt is used to display the speed of the vehicle.

BuzzerIt beeps Whenever any vehicle crosses the speed limit.

WorkingA timer is started inside the microcontroller whenever a low pulse is received on the first sensor. Then microcontroller waits for pulse from second sensor. Timer is stopped whenever low pulse is received on second receiver. Speed = Distance/TimeDistance between sensors are known.Time is calculated by C.Block Diagram

Future ScopeA CCTV Camera can be placed on the highway. If any vehicle has crossed the maximum speed limit then this camera will be triggered to take a picture of the vehicle.We can add voice announcement system. It will intimate the driver that he/she has crossed the over speed condition.We can implement the GSM technology. So that the nearest highway security authorities will be informed about the vehicle which has over speed.
