Distributed remote automatic frequency-conversion device method for diagnosing faults
The present invention relates to Fault Diagnosis Technology of Frequency Converter, a kind of specifically distributed remote automatic frequency-conversion device failure is examined
Since frequency converter becomes increasingly complex, the probability that frequency converter breaks down is also increasing, Accurate Analysis failure cause,
Mass data is generally required, it is more and more difficult for those skilled in the art or computer, with data volume sharp increase,
The method of traditional handling failure data has been not suitable with.
Remote failure diagnosis system is will to diagnose scene and remote fault diagnosis center by network to connect, to realize
A system for the purpose of immediate reaction, resource-sharing, collaborative work, long-range monitoring and remote diagnosis, operation principle be,
Sensor is installed in the engineering machinery to work at the scene, establishes status monitoring point, collecting device status data, as remote failure
The foundation of diagnosis；And establish remote fault diagnosis center in stronger R＆D institution of technical force or enterprise.When field device goes out
When existing failure and Field Force or local fault diagnosis system cannot make diagnosis to it, it will reflect the data of field equipment state
Pass through field monitoring central computer（Client computer）Be sent to remote fault diagnosis center via network, and submit to fault diagnosis and
The services such as remote information consulting.Remote fault diagnosis center is after purview certification, you can starts the phase on long-range server
Function module is answered, real-time information interaction is carried out with user terminal.
Failure is handled by distributed task scheduling mechanism, after frequency converter failure data are collected into, is opened distributed
Accident analysis task, in distributed task scheduling distribution, main part is task distributor.Task-set is by outer input, into task
In distributor.Task distributor is made of multiple queues, and task enters some queue in task distributor.Multiple queues
Weights are different, weights height represent task distribution number, the task from task distributor out enters in node.
The content of the invention
Part in view of the shortcomings of the prior art, the present invention provide a kind of distributed remote automatic frequency-conversion device fault diagnosis
Distributed remote automatic frequency-conversion device method for diagnosing faults of the present invention solves the technology that above-mentioned technical problem uses
Scheme is as follows：The Converter Fault Diagnosis method, by the remote failure diagnosis system based on traditional B/S frameworks, by frequency converter
It is added in distributed system, by C/S frameworks, the fault data of frequency converter is passed into distributed system by network, most
Distance host opens fault restoration program afterwards, and fault restoration program is passed to frequency converter by RPC modes, realizes automatic fault
Detection and reparation.
Preferably, taxonomic revision is carried out to frequency converter failure data first, then, fault parameter number is set on frequency converter
According to transmission program.
Preferably, the setting data receiver program on distance host, the fault data that real-time reception frequency converter sends over,
When detecting fault data, real-time turn-on data analysis program.
Preferably, it if frequency converter generates external fault, can not repair automatically, open and send alarm task；If frequency converter
It can repair automatically, then open fault restoration task, reparation parameter is passed to the control module of frequency converter by RPC modes.
The distributed remote automatic frequency-conversion device method for diagnosing faults of the present invention has the advantage that compared with prior art
It is：Frequency converter based on the remote failure diagnosis system of B/S frameworks, is added to distributed system by the Converter Fault Diagnosis method
In system, frequency converter failure is passed to by distributed system by network, last distance host opens fault restoration program, by failure
Repair procedure passes to frequency converter, realizes the automatic fault detection of frequency converter and repairs；Overcome traditional frequency conversion device fault diagnosis
Present in various drawbacks, improve fault diagnosis efficiency, while improve fault restoration efficiency, have and preferably promote the use of
Description of the drawings
Attached drawing 1 is the flow chart of distributed remote automatic frequency-conversion device method for diagnosing faults.
Understand to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and refer to
Distributed remote automatic frequency-conversion device method for diagnosing faults of the present invention is further described in attached drawing.
Distributed remote automatic frequency-conversion device method for diagnosing faults of the present invention, based on traditional B/S frameworks（Browser/
Server, Browser/Server Mode）Remote failure diagnosis system, frequency converter is added in distributed system, passes through C/
S frameworks（Client/Server frameworks, client-server）, fault data is passed into distributed system by network, most
Afterwards, distance host opens fault restoration program, and fault restoration program is passed through RPC modes（A kind of interprocess communication mode）It transfers
To frequency converter, realize automatic fault detection and repair.In the method for the invention, the stability and reliability of distributed system
It is the key that realize automatic trouble diagnosis technology.
Distributed remote automatic frequency-conversion device method for diagnosing faults described in the present embodiment first carries out frequency converter failure data
Taxonomic revision, as power failure, DC link failure, rectifier fault, fault of converter, control system failure, load faulty,
Motor fault, fuse melting fault lamp；In this process, the various parameters of frequency converter are arranged as far as possible accurate.
Then, fault parameter data sending program on frequency converter is set, when frequency converter breaks down, using C/S frameworks, passes through net
Fault data is sent in distributed type assemblies by network.
The method through this embodiment finally sets data receiver program, real-time reception frequency converter on distance host
The fault data sended over, when detecting fault data, real-time turn-on data analysis program.Such as run into power failure, insurance
When external faults, frequency converter can not be repaired automatically for silk fusing, open task, send the warning informations such as power failure；If become
Frequency device inner parameter goes wrong, and frequency converter can be repaired automatically, can open fault restoration task, will repair parameter and passes through RPC side
Formula passes to the control module of frequency converter.If voltage is excessive, adjustable small resistor etc. realizes the detection of frequency converter automatic fault with repairing
Multiple, external fault and internal part damage then need staff to safeguard.
Attached drawing 1 is the flow chart of the distributed remote automatic frequency-conversion device method for diagnosing faults, as shown in Figure 1, works as change
When frequency device generates failure, by connecting network（If network cannot connect, suspension warning is sent, is attached network）, open
Fault message is sent to distributed system and monitored by data sending program；Distributed system receives number by data receiver program
According to, line number of going forward side by side it is judged that, according to data characteristics（Fault message feature）If frequency converter can be repaired automatically, turn-on data is repaiied
Multiple task if frequency converter can not be repaired automatically, opens and sends alarm task, and the result data of both of these case is sent to
Frequency converter；Can frequency converter progress repair judgement automatically, if cannot repair automatically, manually be repaired, otherwise frequency converter is opened
Control module is opened, performs alarm or self-regeneration program.
Above-mentioned specific embodiment is only the specific case of the present invention, and scope of patent protection of the invention includes but not limited to
Above-mentioned specific embodiment, any person of an ordinary skill in the technical field that meet claims of the present invention and any
The appropriate change or replacement done to it should all fall into the scope of patent protection of the present invention.
