The students of Vidya Academy of Science and Technology, Thalakottukara, have developed an automatic speed control system for vehicles to reduce the possibility of accidents.
Considering the increased rate of accidents, speed control systems have become need of the hour, say the students - C. Sreyas Kumar; Akshay Gopi; Amjad Alikhan; V.N. Vignesh and A. Erik - who developed the Intelligent Speed Adaptation (ISA) system for vehicles.
In the system speed can be automatically controlled by various techniques, which are based on particular zones and traffic density.
“We have developed an automatic speed control system based on RF (radio frequency) signals for accident prone areas, hospitals and school roads, where the speed control within limit is required,” says Sreyas Kumar, one of the students.
The system consists of voice note, fuel cut off and partial braking system. Once the information is received from the zones, the vehicle’s embedded unit automatically alerts the driver, to reduce the speed according to the zone. It will wait for a few seconds, and otherwise vehicle’s ISA unit automatically will reduce the speed.
A spark ignition monitor is connected to IC engine, which dictates the amount of spark voltage produced in the engine according to the engine speed.
This will be the respective input for the two separate differential units. One differential unit will be used to reduce the speed of automobiles having speed above 70 km per hour to the range of 40 to 70 km per hour with the help of pneumatic partial braking system, while the other differential unit will be used to control the speed up to 40 km per hour by fuel cut-off for vehicles of speed range between 40 and 70 km per hour.
The students developed the system under the guidance of Assistant Professors M.S. Aadars, E. Suneesh, Silan Tharakan, V.S. Rakesh and head of the department T.K. Rajendran.
