Inverter monitoring platform and monitoring method thereof

Abstract

The invention provides an inverter monitoring platform and a monitoring method thereof. The inverter monitoring platform, which is installed in a computer, comprises a foreground human-computer interaction module, a core parameter list and a background communication module. The foreground human-computer interaction module comprises a parameter list display module, a parameter setting module, a parameter classification module, a parameter list input / output module, an oscillograph module, a keyboard module and a communication parameter setting module. The core parameter list contains the parameters of an inverter, is used for controlling the inverter and displaying the operation state of the inverter in real time, and serves as a channel for connecting the foreground human-computer interaction module with the background communication module. The background communication module comprises a data structure initialization module, a communication module and a parameter monitoring module. Configuration files are centrally set to be the core parameter list which serves as a channel between the foreground human-computer interaction module and the background communication module, and the invention can quickly select corresponding configuration files for different inverters, and has quick parameter configuration ability.

Description

technical field [0001] The invention relates to a monitoring platform of a frequency converter. Background technique [0002] With the development of power electronics technology, microelectronics technology and modern control theory, frequency converters have been widely used in the speed control of AC motors. Due to the high-efficiency driving performance and good control characteristics of the frequency converter, it is widely used in various industries such as steel, chemical industry, textile, mechanical power, and papermaking. [0003] At present, there are two ways to control the inverter: one is to monitor through a simple small keyboard displayed on a digital tube or LCD screen, and the keyboard is embedded in the inverter; the other is to use a communication cable to connect the computer to the inverter. Directly control the frequency converter through the monitoring platform on the computer. The first way is extremely inconvenient to control the motor due to the...

Problems solved by technology

There are also many inverter manufacturers in China, but many of them do not have a corresponding computer debugging platform, and usually use a simple small keyboard for debugging operations, which is time-consuming and laborious

[0005] In many computer debugging platforms, there are two storage methods for the core parameters. One is a simple storage method similar to text files, which has poor confidentiality and can be modified by the user at will. The motor failure will seriously endanger the personal safety of engineering personnel; the other is to use a highly secure database storage, but first you need to build a database platform, the configuration is cumbersome, and the storage space of the computer is also quite amazing

These two methods are relatively slow when refreshing parameters on the human-computer interface. It is necessary to query the corresponding parameters from a text file or database first, and then read out the parameter content and display it to the user, which is inefficient.
