Description
Technical field
The present invention relates to a kind of methods of diagnostic machinery equipment.
Background technique
The diagnostic device of mechanical equipment is when mechanical equipment produces abnormal transition events, accident etc., based on coming from
The measurement data of mechanical equipment detects the generation of the exception, accident.
Disclosed in patent document 1 using adaptive resonance theory (Adaptive Resonance Theory:
ART diagnostic device).There is the function that multidimensional data is categorized into classification according to its similar degree using the diagnostic device of ART
Energy.In the technology of patent document 1, measurement data when first will be normal using ART is being categorized into multiple classifications (just
Normal classification).Secondly, current measurement data is categorized into classification using ART.It can not be categorized into normally in the measurement data
When classification, new classification (new category) is generated.The generation of new category means that the state of mechanical equipment is changed.
Therefore, abnormal generation is judged using the generation of new category, diagnose in the case where the generation rate of new category has been more than threshold value
For exception.

Patent document 1: Japanese Unexamined Patent Publication 2005-165375 bulletin.
Summary of the invention
(problems to be solved by the invention)
In patent document 1, based on " current measurement data can not be categorized into normal category when, i.e. mechanical equipment
State generates new category when variation has occurred " this premise, and it is judged as abnormal.
However, the state of mechanical equipment not only just changes when producing exception,
Can also it change when timeliness deterioration (aging degradation), operating condition variation.Also, it can also generate at this time new
Classification.Thus, it must not believe that at this time and produce new category, produce the exception of mechanical equipment.
Herein, operating condition refers to environmental condition (atmospheric temperature, the humidity etc. in place set by mechanical equipment
), the amount (mechanical equipment generated energy generated) that is determined by the operation of operator etc. it is not straight with instrument characteristics
Connect the outside environmental elements of relationship.Also, with the presence or absence of be abnormal unrelated, the various measurements if operating condition changes
The value of data also changes.
Although timeliness deterioration, operating condition variation are not exceptions, can be diagnosed in the method for patent document 1
For exception.That is, normal condition can be diagnosed as to exception, as a result become the reason of generating wrong report.
It is an object of the invention to by difference as state change will because timeliness deterioration, operating condition change, it is different
The normal generation rate to reduce wrong report.
(means for solving the problems)
A kind of diagnostic device of mechanical equipment of the invention detects diagnosis according to the measuring signal of diagnosis object mechanical equipment
The exception of object mechanical equipment simultaneously reports exception, and the diagnostic device of the mechanical equipment includes: state change test section, will
The measuring signal of diagnosis object mechanical equipment is categorized into classification to be stored, and sentences in the case where being not belonging to classified classification
It is set to state to be changed；Abnormality determination unit, by signal one as input from state change test section
Divide and is judged to producing exception in diagnosis object mechanical equipment；Generate Alert block, by the defeated of the abnormality determination unit
Outside is arrived in report out；With wrong report blocking portion, detection diagnoses the event other than the exception of object mechanical equipment, and exception is prevented to sentence
Determine the output in portion.
Additionally, it is preferred that wrong report blocking portion includes timeliness degradation portion, which uses diagnosis object machine
The measuring signal of tool equipment finds out weight coefficient, is judged to taking off in the case where the variable quantity of weight coefficient has been more than maximum value
Range from timeliness deterioration, timeliness degradation portion prevent the defeated of abnormality determination unit in the range of no disengaging timeliness deterioration
Out.
Furthermore it is preferred that wrong report blocking portion includes operating condition variation test section, which, which will change test section, to diagnose
The operating condition data classification of object mechanical equipment is stored at classification, is determined as in the case where no generation new category
There is no variation, operating condition variation test sections, and abnormality determination unit is prevented when variation has occurred in operating condition for operating condition
Output.
Additionally, it is preferred that as operating condition variation test section input operating condition data by with constitute diagnosis object machine
The outside environmental elements that the characteristic of the instrument of tool equipment is not directly dependent upon are constituted.
A kind of diagnostic device of mechanical equipment of the invention is examined according to the measuring signal of diagnosis object mechanical equipment to detect
The exception of disconnected object mechanical equipment simultaneously reports exception, and the diagnostic device of the mechanical equipment includes: state change test section,
The measuring signal for diagnosing object mechanical equipment is categorized into classification to store, the case where being not belonging to classified classification
Under be determined as that state is changed；Timeliness degradation portion is asked using the measuring signal of diagnosis object mechanical equipment
Weight coefficient out is determined as the range deteriorated departing from timeliness in the case where the variable quantity of weight coefficient has been more than maximum value
；Operating condition changes test section, and the operating condition data classification for diagnosing object mechanical equipment is stored at classification,
Being determined as operating condition in the case where no generation new category, there is no variations；Abnormality determination unit becomes by state
Change test section be determined as state have occurred variation and by timeliness degradation portion be determined as departing from timeliness deteriorate range and
Being determined as operating condition by operating condition variation test section, there is no being judged to diagnosing object and produce exception when variation
；And Generate Alert block, by the output report of abnormality determination unit to outside.
A kind of diagnostic device of mechanical equipment of the invention, has: measuring signal database, saves diagnosis object machine
The measuring signal of tool equipment；Data extracting unit is handled, is extracted from measuring signal database in order to diagnose diagnosis object
The state of mechanical equipment and the diagnostic signal used；Reference signal data library saves diagnostic signal；Taxon, will
The data classification saved in reference signal data library is at classification；Classification results database, using classification as normal category into
Row saves；Diagnosis unit, using the newest diagnostic signal extracted by processing data extracting unit and in classification results
The information of the normal category saved in database, the state of diagnosis diagnosis object mechanical equipment belong to normal, exception, operating item
Which kind of situation of part variation, timeliness deterioration；Diagnostic result database saves the diagnostic result of diagnosis unit；With to image
The unit of information that display device output saves in diagnostic result database, wherein diagnosis unit have abnormality determination unit,
State change test section, timeliness degradation portion and operating condition change test section, and state change test section has following function
Can: it is not belonging to save in classification results database in the newest diagnostic signal extracted by processing Data extracting section normal
It is determined as that state is changed in the case where classification, timeliness degradation portion has following function: when export normal condition
