There is a problem of unbalanced load of information resources in the transmission of hydropower unit state information, resulting in low transmission speed. The transmission model of hydropower unit state information is constructed based on the data distribution strategy. The unit status information of hydropower station includes the "remote signaling and telemetry" data for monitoring and the interactive data of multiple status detection modules and fault diagnosis modules. The unit status information is extracted by means of periodic acquisition, random acquisition and call acquisition. The time alignment processing method based on asynchronous event driven mechanism is adopted to update all kinds of data received in real time and respond to the network connection and data transmission requests sent by the master station. The data distribution strategy is used to allocate the state information resources of hydropower units to realize the resource collaborative control. Through the response of the data distribution center to the data request, the information transmission is completed according to the size of the data obtained by the data query service. The test results show that the hydropower station unit state information transmission model based on data distribution strategy can improve the transmission speed and provide high-speed and high broadband communication services.
