OBJECTS COUNTER

摘要

The invention relates to a flow sheet object counter. In accordance with the invention, the counter has, for each counting location, two optical transducers consisting of a light source and an optical receiver, equipped with a lens focusing the light beam on a photosensitive element. The photosensitive element generates a signal, which is amplified and shaped by an operating amplifier, and transmitted to a line receiver. Another line receiver receives a reset pulse that cancels a counter, validated by a logic gate. A warning counter generates an acoustic warning signal whenever five empty hooks pass in front of the optical transducers. A seven-element LED screen ensures the display of the bird number by means of decoders.
