Problems solved by technology

[0006] The disadvantage of this solution is that it cannot record continuously, and the data can only be sent to the monitoring software after the frequency converter fills the recording buffer, and the serial port is used to transmit data, which takes a long time
At the same time, the time accuracy recorded by this recording method is not high.

Abstract

The invention discloses a real-time record method and device of data curves of a frequency converter. The method includes the steps that data of all channels of the frequency converter and description information of the data are recorded into a first cache region; data stored in a second cache region are transmitted to external equipment, so that the external equipment conducts related processing on the data; after data reading commands of the external equipment are received, the first cache region and the second cache region are switched, the data of all the channels of the frequency converter and the description information of the data are recorded in the second cache region, and the data stored in the first cache region are transmitted outwards. By the adoption of the method and device, the data curves of the frequency converter can be continuously recorded and checked in real time.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a method and device for real-time recording of data curves of frequency converters. Background technique [0002] Due to its excellent performance and energy-saving features, frequency converters are widely used in modern industrial production processes. In some high-end applications of inverters, such as metallurgical rolling mills, papermaking, and servo drives, in order to meet the needs of actual production and process equipment, there are high requirements for the dynamic response and static accuracy of inverters. Debuggers need to quickly record data curves in real time for analysis, and finally complete the debugging task. At the same time, the real-time data curve record analysis is also of great help to the fault diagnosis of the frequency converter. [0003] One implementation scheme of the existing frequency converter real-time data curve recording funct...
