摘要：PURPOSE:To improve diagnostic accuracy by comparing a predictive information

value being generated by a group-control means with an information value by a group-

control information measured means, and from the difference, diagnosing the presence

of trouble and the extent of predictive accuracy. CONSTITUTION:A group-control means

12 generates group-control predictive information with external equipment information

on a hall call or the like out of an input unit 14 and each cage information out of an

elevator control means 13, and it outputs a control command for group-control to

external apparatuses 18, 20, while the information is stored in a storage means 23. A

measured means 24 measures a value corresponding to the group-control predictive

information, comparing this value with the group-control predictive information stored

by a diagnostic means 25, and it diagnoses the extent of accuracy for the predictive

information and judges the presence of any trouble, thereby outputting it to a

maintenance apparatus 22 via an output means 28 and an input-output unit 21. Thus, it is

accurately diagnosable even against such phenomena as only resulted as a deviations or

the like in the predictive accuracy due to errors of specification selection and equipment

arrangement, building traffic and trouble in equipment.
