Fault finding in an industrial installation by means of a computer
First Claim
1. A method of determining the location of a fault in an industrial installation in whichprior to the fault occurring in the installation, information corresponding to each component part of the installation, including a block diagram thereof, and the correct operating parameters of each component part are stored in a memory device;
- subsequent to the fault occurring in the installation, the operator causes a computer to produce on a visual display unit a block diagram of at least part of the installation and to indicate tests which are to be carried out;
the operator conducts the indicated tests on said part of the installation without removing said part of the installation from the industrial installation,the operator obtains results of said indicated tests and introduces the results into the computer;
the computer compares said results with the corresponding stored information and, as a result of the comparison, indicates on the display device either the component in which the fault lies or further block diagrams and indicated tests which are to be carried out systematically to locate the component in which the fault lies.

Abstract
In a complex industrial installation, it is usually very difficult to locate the position of a fault when one occurs.
In a method of determining the location of a fault, information corresponding to each component part of the installation and the correct operating parameters of each component part is stored in a memory and a computer is used to produce on a visual display unit schematic diagrams of at least part of the installation and indicates tests which are to be carried out, the operator causes the test results to be supplied to the computer and, after comparing the results with the stored information, the computer indicates on the display either where the fault lies or further schematic diagrams and tests which are to be carried out to locate where the fault lies. Apparatus for carrying out the fault location is also described.
