Abstract

The embodiment of the present invention provides a communication data frame structure of a wind power generating set. The data frame structure includes a frame header and data, and is characterized in that the frame header includes: a start flag, which is used to indicate the start of a data frame and a process frame; Sequence, used for data splitting and combination; effective data length, used to confirm the buffer length; data includes: fan attribute data group, used to record the attribute data of the fan itself; and fan collection data group, used to record the fan The component collects data. Through the present invention, both the efficiency and the amount of data transmission of fan data can be taken into account.

Description

technical field [0001] The invention belongs to the field of industrial Internet data communication, and in particular relates to a data frame structure suitable for data transmission of wind power generating sets. Background technique [0002] As a renewable and non-polluting new energy power generation technology, wind power has been widely used, and a large number of wind power generating units have been put into production. The necessary real-time data collected by each wind turbine needs more than 300 pieces, and these data need to be sent to the headquarters. However, the wind power plant is located in a remote area, and the coverage of wired and wireless communication is insufficient, and the problem of low communication bandwidth is common. In order to adapt to low bandwidth conditions, such as the NB system (narrow Internet of Things system) with a bandwidth of only 200kb / s, and to transmit real-time data of wind turbine operation to the big data cloud or data serv...
