AI Technical Summary

Technical Problem

In the existing technology, the waveform data transmission method of frequency converters fails to adaptively adjust according to the relationship between communication transmission time and error rate and waveform sampling time interval, making it difficult to balance the timeliness and completeness of waveform data acquisition.

Method used

By using an adaptive inverter oscilloscope method and system, and with the cooperation of a host computer and an inverter controller, the system dynamically selects between real-time transmission mode and batch transmission mode based on communication transmission time parameters and error rate. This ensures that the waveform data transmission method adapts to the communication link status, thereby achieving the timeliness and integrity of the waveform data.

Benefits of technology

It achieves adaptive adjustment of waveform data transmission mode, taking into account both the timeliness and completeness of waveform data acquisition, and improves system stability and real-time performance during the development and debugging of frequency converters.

Abstract

The application discloses a kind of adaptive frequency converter oscillography method and system.Therein, host computer obtains communication transmission time-consuming parameter and communication error rate according to the communication data between it and frequency converter controller in preset time window, and obtains waveform collection information including waveform sampling time interval and total point number of sampling data;When communication transmission time-consuming parameter is not greater than waveform sampling time interval and communication error rate is less than preset error rate threshold, it is determined as real-time transmission mode, otherwise it is determined as batch transmission mode;In real-time transmission mode, frequency converter controller sends waveform data by sampling time point;In batch transmission mode, waveform data collection and storage are completed first, then sent to host computer.The application can adaptively select waveform data transmission mode according to communication link state, and give consideration to timeliness and integrity of waveform data acquisition.
