Processing plant and control system thereof
First Claim
1. A control system for a processing plant which operates to control the operation of the plant in response to output signals representing the state of various elements of the processing plant wherein the control system comprises means which is operative to generate sound output signals representative of the condition of the machine elements of the plant during operation thereof.

Abstract
A processing plant comprises a control system to control and monitor operation of the machine elements of the plant. The control system comprises a plurality of detecting means each positioned proximate to one of the machine elements of the plant, and which is operative to generate an output signal representative of the condition of operation of the machine element, and to feed such output signal to a central processing unit. In turn, the central processing unit generates an audible output signal which is representative of the sound generated by the machine element during operation thereof, enabling a controller supervising operation of the plant to “hear” the way in which the machine elements are performing.

9. For use with a control system for a processing plant which operates to control operation of the plant in response to output signals representing the state of the various elements of the processing plant,
a supplementary input system operative to generate sound output signals analogous to the sounds produced by the plant during operation thereof.
-
10. A method of controlling a processing plant of the kind utilising a computer to which input signals, representing the state of various machines of the plant and/or representing various stages in a processing operation, are supplied, and from which the computer produces output signals in the form of one or more visual displays and one or more aural displays representing the condition of the plant,
characterised in that the output signals produced by the computer include one or more audible signals analogous to the sound produced by elements of the plant during their operation.

11. A processing plant comprising:
-
a) a plurality of machine elements;
b) a plurality of detecting means each located proximate to one of the machine elements and which is responsive to the condition of operation of the machine element to produce an output signal which is functional of the operating condition of the machine element;
c) a central processing unit to which the output signals from the detecting means are applied; and
d) a plurality of sound generation means each operative under the control of the central processing unit and in response to an input to the central processing unit from the detecting means to generate an audible output signal representative of the operating condition of the machine element to which it is proximate.
