DATA INTERPRETATION NETWORK

摘要

The outputs of four data interpretation circuits connect through a first and second OR gate to either a first or second monoshot circuit. The data interpretation circuits each receive two 90 DEG phase displaced signals and their inversions from a position transducer attached to a numerically controlled machine. As the machine moves, these interpretation circuits detect voltage shifts in the position transducer signals and alternately fire the first and second monoshot circuits to generate a train of pulses at the output of the network as the machine moves. Each data interpretation circuit has two flip-flops each triggered by the output of one of two NAND gates. An output of each flip-flop is connected to an input of the NAND gate connected to the other flip-flop. This inhibits the actuation of one flip-flop after the other flip-flop is triggered and the machine remains within predetermined limits such as occurs during vibration.
