Problems solved by technology

[0003] Although wind power has the advantages of being clean, renewable, and low-cost, it also has defects such as high geographical requirements and being distributed in the wild. Therefore, how to collect data from wind power equipment is the basis for automatic management and data monitoring
In the prior art, the wind power equipment data is sent to the remote early warning and diagnosis center, but the network structure of this structure is very simple. Once the network or any link in it fails, the data will be lost. Therefore, the existing wind power unit data interface poor reliability

Embodiment Construction

[0028] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0029] An embodiment of the present invention provides a wind turbine data interface caching method, the process of which is as follows figure 1 shown, including:

[0030] Step 1. Determine whether the communication with the remote early warning and diagnosis center is normal; if not, then jump to step 2;

[0031] Step 2, dividing the cache area in the locally preset storage module;

[0032] Step 3, cache the real-time operation data of the local wind turbine in the cache area;

[0033] Step 4. Judging whether the communication with the remote early warning and diagnosis center is back to normal, if yes, sending the real-time operation data in the buffer area to the remote early warning and diagnosis center; otherwise, return to step 3.

[0034] The m...

Abstract

The invention provides a caching method and system for a data interface of a wind turbine generator. The method comprises the following steps: step 1, judging whether the communication with a remote prewarning diagnosis center is normal or not, and if not, jumping to step 2; step 2, marking out a caching region in the locally preset memory module; step 3, caching real-time service data of the local wind turbine generator in the caching region; and step 4, judging the communication with the remote prewarning diagnosis center gets back to normal or not, if yes, sending the real-time service data in the caching region to the remote prewarning diagnosis center and if not, returning to the step 3. The method and the system, provided by the embodiment of the invention, adopt the dynamic memory data storage technology to send the real-time service data from the wind turbine generator and data of an equipment vibration state monitoring system to a remote data center through a caching interface, thereby, improving the system reliability and preventing data loss.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data interface caching method and system for a wind turbine. Background technique [0002] With the increasing depletion of energy and increasing pollution, renewable energy and clean energy are getting more and more attention. Wind power generation or wind power generation is a clean renewable energy, and the operating cost of wind turbines is low. Therefore, wind power technology and equipment is an important part of the wind power industry, and it is also the foundation and guarantee for the development of the wind power industry. [0003] Although wind power has the advantages of being clean, renewable, and low-cost, it also has defects such as high geographical requirements and being distributed in the wild. Therefore, how to collect data from wind power equipment is the basis for automatic management and data monitoring. In the prior art, the wind power eq...
