OBSTRONICS SYSTEM: MAIN FEATURES OF THE PROJECT

1. Effective in implementation.
2. Low power consumption, and compact size,
3.High reliability, due to the usage of powersemiconductor devices,
4.Greater control range due the usage of Frequency Modulation with a PC.
5.Vehicles monitored from a remote area (no need of ‘line-of-sight’ arrangement).

BLOCK DIAGRAM & ITS DESCRIPTION

In BRIEF: This ‘Smart Zone Sensing System with Automatic Control’ system works like this. Each monitoring zones are fitted with RF Transmitter units with unique Identity Code. All the vehicles must be fitted with RF Receiver and respective circuitry on their vehicle’s number plate. Display will be fitted on the dash board for visual representation of the alert messages sent by respective zone Transmitters.

When vehicle with 70 Kmph speed enters the school zone, it receives the alert message”School Zone, Please go slowly. Speed limit it 30 KiloMeterPerHour”. Also receiver checks the speed limit of the vehicle and found above 30 kmph then reduces it until crosses the School Zone area.

When the same vehicle enters the Hospital Zone, it receives the alert message “Hospital Zone, Please do not blow Horn”, and reduces the supply voltage to minimum level such that horn should blow in low pitch.
