drunken driving vehicle detection

The purpose of this project work is to detect the drunken driving vehicles through remote monitoring system. The receiver can be installed at police stations or check posts. Whenever the drunken driving vehicle reaches to a particular zone where the receiver is installed, immediately the alarm in the receiver energizes automatically and displays the vehicle data including its number. To prove the concept practically, each and every vehicle must be installed with Alcohol sensor at steering wheel. All the vehicles transmitters must be tuned with single receiver; the synchronized receivers can be installed at everywhere can communicate with each and every vehicle and there by wherever the vehicle goes it is detected. Since it is a prototype module for demo purpose, the system is constructed with one set of RF module operates at 433 MHz. TGS813 used as Alcohol sensor is wired with voltage comparator, which generates a high signal for the controller and based on this signal the controller transmits the information about the drunken driving vehicle. The information contains a) type of vehicle, b) color, and c) vehicle registration number. This is the information already stored in the data-transmitting controller and whenever the sensor is affected same information is transmitted and it is displayed in the receiver unit. The system is quite useful at highways
