Title:
DEVICE FOR DIAGNOSING FAILURE
Document Type and Number:
Japanese Patent JPH04260902
Kind Code:
A
Abstract:
PURPOSE:To judge the existence of a true failure when a practical state is different from set operation condition data and to judge the sort of the failure. CONSTITUTION:A failure judging part 107 compares the control operation of a control part 104 monitored through a monitor part 105 with operation control data stored in a storage part 106 and judges whether a failure is generated or not. When the judging part 107 judges the generation of a failure, a failure inferring part 108 infers the sort of the failure and the validity/invalidity of the failure judgement based upon a rule (inference data) stored in a rule storing part 109.
