| 摘要 |
<p>The invention relates to a method for detecting the presence of moving objects. According to the invention, a detection system is used to: emit a series of electromagnetic radiation beams using emitting devices (De) belonging to an emitting unit (1), which are aligned to form at least one emitting column (E1); receive the electromagnetic radiation beams at receiving devices (Dr) belonging to a receiving unit (2), which are aligned to form at least one receiving column (R1) facing the emitting column (E1); detect the interception of said beams by detection of the absence of electromagnetic radiation reception by at least one of the receiving devices (Dr) and generate a signal indicating the detection of a moving object when the number of receiving devices (Dr) that detect the absence of electromagnetic radiation reception is above a pre-determined number greater than two.</p> |
