Abstract

Abstract A method is provided of designing a monitoring and control system for laboratory and industrial process applications. The method consists of specifying the instruments and controllers to be used for monitoring and control using a graphics and natural language interface, linking the graphical description of the instruments and controllers to the external instruments and controllers through an electronic interface, building an expert system knowledge base for supervising the control of the process or laboratory experiment, defining the inference engine which actually runs the process or experiment, and using the graphics and natural language interface to query the system in real time. Apparatus incorporating this method is also provided.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 97 words
A method of designing a monitoring and control system for laboratory and industrial process applications comprising the steps of: specifying the instruments and controllers used for monitoring and control using a graphics and natural language interface, linking the graphical description of the instruments and controllers to the external instruments and controllers through an electronic interface, building an expert system knowledge base for supervising the control of the process or laboratory experiment, defining the inference engine which actually runs the process or experiment, and using the graphics and natural language interface to query the system in real time.
Claim 2
Independent Claim 97 words
A method of designing a monitoring and control system for laboratory and industrial process applications comprising the steps of: specifying the instruments and controllers used for monitoring and control using a graphics and natural language interface, linking the graphical description of the instruments and controllers to the external instruments and controllers through an electronic interface, building an expert system knowledge base for supervising the control of the process or laboratory experiment, defining the inference engine which actually runs the process or experiment, and using the graphics and natural language interface to query the system in real time.
Claim 3
Dependent Claim 16 words
The method of claim 1 on which the graphics and natural language interface is in Prolog.
Claim 4
Dependent Claim 30 words
The method of claim 2 wherein the graphics include ICONS and the functional characteristics of the ICONS include procedures written in a procedural language such as C or assembly language.
Claim 5
Dependent Claim 21 words
The method of claim 1 wherein a window facility is used to draw variants of the process or laboratory experiment schematics.
Claim 6
Dependent Claim 52 words
The method of claim 2 in which the interface permits constructing the elements of the process or laboratory control system by specifying the functional characteristics of the elements without setting out the order in which they are to be used, the order of operation is being automatically inferred by the inference engine.
Claim 7
Dependent Claim 14 words
The method of claim 5 in which the inference engine is programmed in Prolog.
Claim 8
Dependent Claim 34 words
The method of claim 1 wherein the interface permits the user to specify the functional characteristics of the process control elements using the graphics and natural language interface via a mouse and keyboard respectively.
Claim 9
Dependent Claim 23 words
The method of claim 1 wherein the linking between the graphics and the external instruments and controllers is implemented using a frame structure.
Claim 10
Dependent Claim 14 words
The method of claim 8 wherein Prolog is used to implement the frame structure.
Claim 11
Dependent Claim 36 words
The method of claim 1 wherein the inference engine is defined into a first part which enables the monitoring of processes and instruments, and a second part dealing with the control of the process or instruments.
Claim 12
Dependent Claim 13 words
The method of claim 10 wherein the inference engine is implemented in Prolog.
Claim 13
Dependent Claim 33 words
The method of claim 1 wherein the expert system knowledge base uses expert knowledge in the form of heuristics to make control decisions based on data input from the laboratory experiment or process.
Claim 14
Dependent Claim 34 words
The method of claim 12 wherein the user is able to modify the knowledge base of the expert system by adding and deleting Prolog facts and predicates using the graphics and natural language interface.
Claim 15
Dependent Claim 102 words
Apparatus for designing a monitoring and control system for laboratory and industrial processes comprising: instruments and controllers positioned in the process for reading and controlling process data; a graphics and natural language interface for specifying the instruments and controllers used for monitoring and control; an electronic interface linking the graphical description of the instruments and controllers to the external instruments and controllers; an expert system knowledge base for supervising the control of the process or laboratory experiment; an inference engine which actually runs the process or experiment; and the graphics and natural interface including means to query the system in real time.
Claim 16
Dependent Claim 102 words
Apparatus for designing a monitoring and control system for laboratory and industrial processes comprising: instruments and controllers positioned in the process for reading and controlling process data; a graphics and natural language interface for specifying the instruments and controllers used for monitoring and control; an electronic interface linking the graphical description of the instruments and controllers to the external instruments and controllers; an expert system knowledge base for supervising the control of the process or laboratory experiment; an inference engine which actually runs the process or experiment; and the graphics and natural interface including means to query the system in real time.
Claim 17
Dependent Claim 17 words
Apparatus as claimed in claim 14 in which the graphics and natural language interface is in Prolog.
Claim 18
Dependent Claim 31 words
Apparatus as claimed in claim 15 wherein the graphics include ICONS and the functional characteristics of the ICONS include procedures written in a procedural language such as C or assembly language.
