In the case of a relatively small number of operators in the central control room of the crushing workshop,in order to enable the operators to timely obtain equipment fault alarm information,a unified voice alarm system is established for fault alarm.The voice alarm system can timely broadcast equipment alarms and fault information through voice,and store the corresponding alarm and fault information for later retrieval and summary.The application of the voice alarm system in the automated control system of the crushing workshop can avoid accidents caused by the untimely discovery and handling of equipment faults by the operators in the centralized control center,effectively improving the alarm processing rate of the crushing workshop and ensuring safe production.The practical application effect is good.
