Abstract
Abstract The effectiveness of a RIC remote diagnostics system is improved by reducing the quantity of data required to perform diagnostics. More specifically, a machine (10) being remotely monitored acquires a data summary of key performance parameters and transmits the data summary to a remote server (95). The remote server analyzes the data summary and can query for more specific non- volatile memory data in specific areas if the remote server determines that further information is needed to complete the diagnostics. The system involves interaction between low level diagnostic software (120) associated with the machine and high level diagnostic software (140) located at the remote site (70).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
A system for collecting and transmitting diagnostic physical data of a machine to a remote site for monitoring and analyzing machine operation, the machine having plural operating components, control software for operating said components, and a memory for storing said control software; the system comprising: means for periodically collecting physical data relating to said machine in said memory; a communication channel coupling said machine to said remote site; non-volatile memory means for storing optimum operating parameters for said machine; software control means for performing preliminary diagnostic analysis of said physical data stored in said memory to derive a data summary containing key diagnostic parameter data relating to operation of said machine, said key diagnostic parameter data comprising only a portion of all of said physical data; data transfer means for transmitting said summary data over said communication channel to a remote site; and a remote diagnosis expert system at said remote site for further diagnostic analysis of said transmitted data summary.
Claim 2
Dependent Claim
29 words
A system as claimed in claim 1, further comprising a memory at said remote site for storing at least a portion of said data summary to form a log.
Claim 3
Dependent Claim
36 words
A system as claimed in claim 1 or claim 2, further comprising a termination means for terminating communication with said machine if all parameters within said data summary are determined to be in a normal range.
Claim 4
Independent Claim
44 words
A system as claimed in any one of the preceding claims, further comprising a query means for querying said software control means of said machine for transmission of more specific physical data relating to specific parameters determined not to be in a normal range.
Claim 5
Independent Claim
63 words
A system as claimed in any one of claims 1 to 3, further comprising a query means for initiating bidirectional communication with said software control means through said communication channel, said query means querying requests for further specific physical data regarding parameters analyzed as abnormal, said expert system utilizing said further specific physical data to further analyze and diagnose operation of said machine.
Claim 6
Independent Claim
21 words
A system as claimed in any one of the preceding claims, wherein the remote diagnosis expert system includes a knowledge base.
Claim 7
Independent Claim
175 words
A method of monitoring and diagnosing operation of a machine from a remote site, the method comprising the steps of: (a) periodically collecting physical data relating to operation of a machine and storing said physical data in a memory associated with said machine; (b) performing preliminary diagnosis of said physical data by diagnostic software associated with said machine to derive a data summary of key parameters of said physical data; (c) transmitting said data summary over a communication channel to the remote site; (d) performing additional diagnostic analysis of said machine by analyzing said data summary using further diagnostic software to determine if said machine is operating within a normal range; (e) querying said diagnostic software of said machine for further specific physical data if any parameters of said data summary are not in a normal range, said further specific physical data pertaining only to specific areas related to parameters of said data summary diagnosed as not in a normal range; and (f) conducting more detailed diagnostic analysis based on said further specific physical data.
Claim 8
Dependent Claim
24 words
A method as claimed in claim 7, further comprising the step of predicting a corrective action to return said machine to a normal operation.
Claim 9
Dependent Claim
25 words
A method as claimed in claim 8, further comprising the step of automatically remotely adjusting said machine to return said machine to a normal operation.
Claim 10
Independent Claim
28 words
A method as claimed in any one of claims 7 to 9, wherein step (b) includes converting said physical data into linguistic labels which describe said physical data.
Claim 11
Independent Claim
33 words
A method as claimed in any one of claims 7 to 10, wherein step (b) derives said data summary in a common format which accommodates diagnostic analysis of a multiplicity of different machines.
