The overload indicator is built around the operational amplifier CA3140 (IC1). Set the reference voltage (depending on the desired speed) by setting the VR1 preset on pin 2 of IC1. When the voltage developed at the pin 3 of IC1 is greater than the reference voltage at the pin 2, the output pin 6 of the comparator IC1 rises to the sound pickup PZ1 and illuminates the LED 3. The rotation indicator circuit is built around Of the AND gate 74LS08 (IC2). The pin 2 of the gate N1 rises as the motor rotates in the forward direction, whereas the pin 1 o ....etc

Abstract:

The Object of this project is to detect the speed of the vehicle and cutoff the fuel if it exceeds set speed. This project is designed with micro controller, Proximity Sensor asspeed sensor and driver circuit with Relay and keypad.In this project we are using Proximity sensor as a speed detector. A Proximity sensor can detect objects without physical contact. A proximity sensor often emits an electromagnetic field or beam and look for changes in the field. The object being sensed is often referred to as the proximity sensor's target ....etc

OVERSPEED DETECTOR FOR VEHICLE CONTROL SYSTEM
Abstract:
The Overspeed Detector for Vehicle Control Systems comprises a pair of high pass filters, having inputs governed by the actual vehicle speed signal, which deliver outputs only provided that the frequency of the inputs is above the frequency for the high pass filters, and the checking means includes an oscillator which generates a check signal with a frequency higher than the frequency of the high pass filters. The switching means alternately applies the check frequency to ....etc

Abstract

Our proposed project aims to develop a system that detects cars driving at speeds over specified limit and inform concerned authorities immediately. Road accidents occurrences have increased recently so there needs to be a system that allows to detect over speeding cars. Current speed detection systems are handheld guns held by police personnel that allow them to check car speed and then manually inform authorities about the vehicle. Whereas this proposed system does not need any human interception and records car speed as well as wir ....etc
