Ultrasonic displacement sensor using digital signal processing detection |
摘要 |
An apparatus and method is provided for detecting motion or displacement of an object in a monitored zone. The apparatus is disposed between a load and a power source and comprises a transmitter for providing a pulsed signal within a monitored zone. The pulsed signal interacts with objects in the monitored zone and provides a return signal. A receiver receives echoes from a return signal of the pulsed record signal, and a microcontroller circuit processes the echoes. The processing involves extracting a kernel from the return signal and multiplying the kernel by the stored return signal.
