Expansion of Space of the Choice of Tone Signals for the Technological Alarm System on the Basis of Industrial Controllers
O.L. Akhremchik, I.I. Basulev

Expansion of number of tone signals in PLC with the firmware sound speakers is offered. Frequency of an audio signal is defined by requirements of standard documentation at operation of the notifying, preventive and emergency alarm systems. In case of excess of the value of a run time of the sequence of actions for elimination of the reasons of operation of the alarm system established for group of users or realization of the irregular actions there is an operation of the alarm system to change of frequency of an audio signal. For formation of additional audio signal impulses of the increasing frequency, effects of an echo and change of a form of a signal with sinusoidal on sawtooth are used. The research of the action sequence realization by the operator at control of the multi-engine drive after operation of the alarm system showed that variation of a run time of actions when using additional audio signals decreases in the absence of mistakes.
Keywords: time; action; audio signal; user; properties; alarm system; control, frequency.
