Frequency converter monitoring method and system

Abstract

The invention discloses a frequency converter monitoring method. The frequency converter monitoring method comprises the steps that a CSV parameter file is called from a CSV parameter file database according to a calling instruction and is analyzed, data information obtained after analysis is stored to an internal storage chain table and displayed in a catalog mode, communication with a frequency converter is carried out through a modbus protocol according to the data information in the internal storage chain table, the working condition information of the frequency converter is obtained, and the data information in the internal storage chain table is updated. Due to the fact that the CSV parameter file is an editable file, when the functions of the frequency converter are modified according to needs of a user, a developer only needs to edit the original CSV parameter file again and modify or add or cancel data content in the original CSV parameter file according to the modification of the frequency converter and does not need to develop or compile the whole CSV parameter file, and therefore field debugging and the integrated development progress are improved.

Description

technical field [0001] The present application relates to the technical field of power equipment monitoring, in particular to a method and system for monitoring frequency converters. Background technique [0002] The main function of the frequency converter monitoring system is to monitor the running state of the frequency converter. The running state of the frequency converter mainly includes: the operating parameter information of the frequency converter, the fault information of the frequency converter and the waveform display of the frequency converter running. These pieces of information are obtained through data interaction with the frequency converter. [0003] In the prior art, when the frequency converter monitoring system is used to monitor the frequency converter, the frequency converter monitoring system generally communicates with the frequency converter based on fixed hard-coded communication data, and the communication data contains fixed hard-coded frequency ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, this application provides a method and system for frequency converter monitoring, which is used to solve the problem of communication with the frequency converter based on the fixed fixed communication data generally used in the frequency converter monitoring system in the prior art. When the function is modified, developers need to develop and compile the communication data as a whole, which will affect the on-site debugging and the overall development progress.
