Embodiment
[0015] The distributed remote automatic frequency converter fault diagnosis method described in this embodiment first classifies and sorts the fault data of the frequency converter, such as power supply fault, DC link fault, rectifier fault, inverter fault, control system fault, load fault, motor fault , Fuse blown fault light; in this process, the various parameters of the inverter should be sorted out as accurately as possible. Then, set the fault parameter data sending program on the frequency converter. When the frequency converter fails, use the C / S structure to send the fault data to the distributed cluster through the network.
[0016] Through the method described in this embodiment, a data receiving program is finally set on the remote host to receive the fault data sent by the frequency converter in real time, and when the fault data is detected, the data analysis program is started in real time. In case of external faults such as power failure and fuse blown, the inv...

The invention discloses a distributed remote automatic frequency converter fault diagnosis method, and relates to a frequency converter fault diagnosis technology. Through a remote fault diagnosis system based on a conventional B / S architecture, a frequency converter is added to a distributed system, through a C / S architecture, fault data of the frequency converter is transmitted to the distributed system through a network, and finally, a remote host starts a fault restoration program to transmit the fault restoration program to the frequency converter through an RPC mode so as to realize automatic fault detection and restoration. According to the invention, the various disadvantages existing in conventional frequency converter fault diagnosis are overcome, the fault diagnosis efficiency is improved, and the fault restoration efficiency is enhanced at the same time.
Description
technical field [0001] The invention relates to a frequency converter fault diagnosis technology, in particular to a distributed remote automatic frequency converter fault diagnosis method. Background technique [0002] As the frequency converter is becoming more and more complex, the probability of failure of the frequency converter is also increasing. Accurate analysis of the cause of the failure often requires a large amount of data, which is becoming more and more difficult for ordinary technicians or computers. With the rapid increase in the amount of data, The traditional methods of dealing with fault data are no longer suitable. [0003] The remote fault diagnosis system is a system that connects the diagnosis site and the remote fault diagnosis center through the network to achieve instant response, resource sharing, collaborative work, remote monitoring and remote diagnosis. Install sensors on machinery, establish status monitoring points, and collect equipment sta...
