Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] The invention discloses an object passing detection system that uses a reflector to realize W-shaped light rays, and is used for detecting whether there is an object passing through in a region. The detection system includes a photoelectric switch and a reflector correspondingly arranged on the opposite side frame of the detection region The light emitted by the transmitting end of the photoelectric switch is reflected back and forth by the corresponding reflective mirror to form multiple light rays covering the detection area and received by the receiving end of the photoelectric switch. When an object enters the detection area and blocks at least one of the multiple light rays By triggering the photoelectric switc...

Abstract

The invention discloses an object passing detecting system and a method thereof. The object passing detecting system comprises a photoelectric switch and reflectors which are correspondingly arranged at opposite-side frames of a detecting area. The light which is transmitted from the transmitting end of the photoelectric switch is repeatedly reflected through the reflectors that are correspondingly arranged, thereby forming W-shaped light which covers the detecting area and is received by the receiving end of the photoelectric switch. The object passing detecting system can improve accuracy in object passing detection. The object detecting system has advantages of simple structure, low cost, least number of photoelectric switches, and stable and reliable detecting signal.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to an object passing detection system and method. Background technique [0002] In industrial automation production equipment or monitoring systems, it is often necessary to detect whether an object passes through a fixed area. The common method is to use a photoelectric switch. Usually, the through-beam photoelectric switch is arranged in a fixed area, and the measuring light 3 emitted by the transmitting end 1 of the photoelectric switch passes through the detection area 4 from the cross-sectional direction of the object, and the light is received by the receiving end 2 of the photoelectric switch. When no object passes through the area, the receiving end 2 of the photoelectric switch can receive light, which means that no object passes through, such as Figure 1a As shown; when the passing object 5 passes through the detection area 4 longitudinally, it will block the measurin...
