摘要： A vehicle speed monitoring system has a pair of parallel piezoelectric sensors or pressure transducers carried in closely spaced relation by a common elastomeric carrier such that the distance D between the sensors is maintained constant. A time measuring circuit connected to the sensors measures the time between peak voltages induced in the piezoelectric sensor transducers which is used to calculate and display vehicle speed. A weight is secured to or embedded in the carrier to cause the carrier to hug the roadway and be immune to lifting because of air currents and turbulence.

摘要： A vehicle detector for detecting a moving vehicle traversing a predetermined roadway includes a coil antenna for detecting electromagnetic radiation inherently generated and emitted by the vehicle as it traverses the predetermined path and producing a first signal. A low noise amplifier receives and amplifies the first signal and outputs an amplified first signal to a differential full wave amplitude modulation envelope detector and produces a second signal. A high pass filter having a predetermined cutoff frequency is connected to receive the second signal and output only third signals having a magnitude proportional to the electromagnetic signal being detected. A converter circuit converts the third signals to a digital signal, the converter circuit including a switching comparator having a source of a stable voltage reference level and outputting a fourth signal. A hysteresis detector causes the comparator to switch upon detection and thereby prevent output switching due to slower or noisy input signals, and a utilization device is connected to receive and be actuated by the fourth signal.
