PROCESS CONTROL METHOD AND DEVICE

摘要

microelectronic devices for process control in all engineering arts. SUBSTANCE: method involves use of logic integrated circuits, primarily digital ones, for controlling processes by recording and processing analog signals characterizing these processes. Process control signal is generated by means of integrated circuit K56LA7 when analog signal characterizing state of one of process variables is applied to one of its inputs and signal coming from pulse generator whose oscillating period is at least 1000 times shorter than analog signal variation time, to one of its remaining inputs. EFFECT: enhanced precision of process implementation. 2 cl, 1 dwg
