Converter station data security protection method based on data encryption and trajectory tracking technology

The invention provides a converter station data security protection method based on a data encryption and trajectory tracking technology, and the method comprises the steps: collecting the data information of each subsystem and auxiliary equipment of a converter station in a security region, uploading the data information to an edge Internet-of-Things agent module, monitoring and collecting the power-on operation state of a terminal, and carrying out the data encryption and trajectory tracking. A unique communication identifier is distributed to the new acquisition terminal; the cloud server scans the running edge Internet of Things agents, and finds whether a new edge Internet of Things agent is online or whether an edge Internet of Things agent quits running; analyzing the use state and the potential safety hazard of each subsystem and auxiliary equipment in the converter station to obtain a corresponding solution, and transmitting the solution to the information management subsystem; and the information ma
