Electronic rail waggon counting system - has two pedals spaced at 2600 mm on one rail and third at 3700 mm from furthest on other rail

摘要

The system is for counting railway waggons and comprises three electronic pedals of which two are arranged on one rail at a distance of 2600 mm whilst the third is on the other rail at a distance of 3700 mm from the farthest pedal. The system for logic discrimination of goods waggons uses two electronic pedals at a distance of 2600 mm which activate two sets of bi-stable circuits whose symmetrical states of the OR-exclusive connections can be compared and whose outputs activate the bistable circuit via the OR-connection. This circuit may operate a waggon counter via an amplifier.
