The invention relates to a one-transmitting multi-receiving data transmission method based on a data management service platform CIS interface, and belongs to the technical field of a power system data transmission method. In the one-transmitting multi-receiving data transmission method based on the data management service platform CIS interface, data exchange is carried out between a data sending party and a data using party of a data management service platform by the data management service platform CIS interface. According to the data transmission method disclosed by the invention, one-transmitting multi-receiving data transmission is implemented by the CIS interface; the data sending party firstly sends shared data to a data center for storage, and the data using party takes the data as required, so that cost and resources are saved; and the one-transmitting multi-receiving data transmission method is more convenient, rapid and safe in data transmission.
