Abstract
A process, such as for instance the operation of a machine, is automatically supervised by monitoring at least two of the operational parameters which are desired to have a prescribed relationship to each other. A curve is formed which graphically represents the actual monitored relationship of the parameters, and it is compared to a standard curve representing the desired relationship of the parameters. In the event of a deviation between the curves, a signal is produced to indicate such deviation. An apparatus for carrying out the method is also disclosed.
Claims10
A method of monitoring a process which involves a plurality of parameters, comprising the steps of monitoring at least two of the parameters of said process which are desired to have a prescribed relationship to each other;
- forming a curve which graphically represents the actual relationship of said parameters to each other;
- comparing the thus obtained curve to a standard curve which represents the desired relationship of said parameters;
- and producing a signal in the event of a deviation between said curves.
A method as defined in clain 1, wherein said standard curve is obtained empirically.
An apparatus for monitoring a process which involves a plurality of parameters, comprising first means for monitoring at least two of the parameters of said process which are desired to have a prescribed relationship to each other;
- second means for forming a curve which graphically represents the actual relationship of the monitored parameters;
- third means for comparing the thus obtained curve to a standard curve which represents the desired relationship of said parameters;
- and fourth means for producing a signal in the event of a deviation between said curves.
