Abstract

The invention relates to a wind turbine generator data transmission method and system based on Beidou short messages and a computer storage medium, and belongs to the technical field of Beidou satellite communication. According to the invention, the Beidou short message is utilized to transmit the wind turbine data, if the length of the wind turbine data to be transmitted exceeds the single capacity upper limit of the Beidou short message, the wind turbine data to be transmitted is subjected to subpackaging, each obtained subpackage is transmitted, whether packet loss exists is judged after the subpackage transmission is finished, and the lost packet is retransmitted. When the invention utilizes the Beidou short message to carry out subpackage transmission, only the lost message is required to be retransmitted, all subpackages are not required to be retransmitted, transmission resources are saved to a great extent, and the transmission efficiency is improved to a certain extent.

Description

Wind turbine generator data transmission method, system and computer storage medium based on Beidou short message Technical Field The invention relates to a wind turbine generator data transmission method and system based on Beidou short messages and a computer storage medium, and belongs to the technical field of Beidou satellite communication. Background In order to ensure reliable operation of wind turbines, the wind turbine data need to be reported at regular time (for example, once in 15 minutes), and the wind turbines are mostly distributed in areas with remote positions and lack of reliable public networks, so that the traditional communication mode is high in cost or unstable, the communication range of a Beidou satellite navigation system is wide in coverage, reliable communication can be realized in remote positions, and for this purpose, the transmission of the wind turbine data by adopting the Beidou satellite navigation positioning system is proposed, for example, a Chinese patent application file with the application publication number of CN119421120A is provided, and the file discloses a wind turbine fault transmission system and a method based on Beidou short messages, which relate to the technical field of wind turbine data transmission. Transmitting the wind turbine data to the Beidou transmitting end receiving and transmitting device, receiving the wind turbine data in the short message form by the Beidou transmitting end receiving and transmitting device, transmitting the wind turbine data in the short message form to the Beidou receiving end receiving device through the Beidou satellite, receiving the wind turbine data in the short message form transmitted by the Beidou satellite by the Beidou receiving end receiving and transmitting device, and transmitting the wind turbine data in the short message form to the receiving end gateway server. The maximum length of messages in the first-generation and second-generation short message communication of the Beidou satellite navigation positioning system is only about 120 bytes, the service capacity of the Beidou third-generation short message communication service is increased to 1000 ten thousand times/hour, the single communication capacity is 1000 Chinese characters, the data volume of each transmission of the Beidou short message communication is very limited, the transmission frequency is also greatly limited (one minute or half minute is transmitted), the data of all wind turbines of the whole wind power plant are generally transmitted simultaneously when the wind turbine data are transmitted, and when the number of wind turbines in the wind power plant is relatively large, the transmitted data volume exceeds the upper limit of the single capacity of a Beidou short message terminal, so that the data are required to be packetized, and each packet is transmitted according to the Beidou short message mode.
