DEVICE FOR SIGNALING DEVIATIONS OF PARAMETERS FOR TOLERANCE CONTROL Russian patent published in 2017 - IPC G08B23/00 

FIELD: radio engineering, communication.

SUBSTANCE: device parameter deviations alarm for limit test consists of: "Start" button; RS-flip-flop; three AND gates and one OR gate; two blocks and elements; Counting frequency generator; two pulse counters; encoder and decoder; switch; Sensor-controlled channels; shapers of signals "a deviation upward" and "downward deviation"; period pulse sequence generator; two pulse generators; two single pulse generators; a shift register; memory units, display, reverse registers, a reset state, an alarm identification, analysis, the two-step search signal; controller. The new device is a controller for periodical monitoring of the observed variable for controlling the parameters of objects and consisting of a divider, counter, memory element, an element of comparison, coefficients setting element, the multiplication element, clock generator controlled by a divider, as well as the aggregate of new connections.

EFFECT: device will increase the speed of a two-stage Search alarm system in a multi-channel control by controlling the parameters of the frequency depending on the speed of change and adaptive change preview channel length in the first phase Search alarm.
