DETECTION SYSTEM FOR DROPPING OBJECTS

摘要

A system for the detection of fast-moving dropping objects includes a submitting plate, a receiving plate, and a microcontroller. The submitting plate includes a first submitting pipe, a second submitting pipe, and a third submitting pipe. The first, second, and third submitting pipes emit infrared rays in turn. The receiving plate includes a first receiving pipe, a second receiving pipe, and a third receiving pipe. An object passage is defined between the receiving plate and the submitting plate, and the activation of the submitting pipes in turn detects individual objects even if one of a number of the falling objects obscures another falling object.
