Real-time Ethernet-based data acquisition system and data acquisition method for wind-driven generator

Abstract

The present invention provides a real-time Ethernet-based data acquisition system and a data acquisition method for a wind-driven generator. The real-time Ethernet-based data acquisition system for the wind-driven generator comprises a fan controller, a protocol converter, a data acquisition unit, a data server and a database. The fan controller is used for sending to-be-acquired data to the protocol converter based on the TCP protocol. The protocol converter is connected with the fan controller and is used for converting the TCP protocol of the fan controller into the real-time Ethernet protocol, and then sending the real-time Ethernet protocol to the data acquisition unit. The data acquisition unit is used for storing acquired data into a file at a certain time interval. The data server is used for acquiring a data file from the data acquisition unit. The database is used for storing the data file acquired by the data server. According to the technical scheme of the invention, the real-time Ethernet-based data acquisition system and the data acquisition method for the wind-driven generator are good in real-time performance and excellent in stability.

Description

technical field [0001] The invention relates to a real-time Ethernet-based wind power generator data collection system, and also relates to a real-time Ethernet-based wind power generator data collection method, which belongs to the field of industrial control. Background technique [0002] At present, there are mainly the following methods for wind turbine data collection: [0003] 1. Collect data through wind field SCADA system. The frequency of this data collection method is relatively slow, generally at the level of seconds. Since the execution cycle of the wind turbine control program is generally at the level of 10 milliseconds, this data collection method will miss a large amount of valid data. [0004] 2. Through a dedicated data acquisition machine. The communication mode of the dedicated data acquisition machine is generally as follows: the physical layer adopts the network cable of RJ45 connector; the medium access control sublayer in the data link layer adopts ...

AI Technical Summary

Problems solved by technology

Due to the large number and variety of devices connected to the wind farm network, there are problems such as delay, jitter, and load imbalance in the network, and the network environment is complex, and because the TCP protocol itself does not have real-time performance, the packet loss and retransmission of the TCP protocol is reliable. The performance guarantee mechanism will take up a lot of resources during the execution process, so it is difficult to guarantee real-time performance in this data collection method
