Method for realizing plug and play of traditional spaceborne device/load

The invention discloses a method for realizing the plug and play of a traditional spaceborne device/load. The method comprises the following steps: firstly, selecting a common bus, designing an intelligent interface module for the spaceborne device/load, defining self-describing file xTEDS (Transducer Electronic Data Sheets), and providing device information, input and output interfaces, input and output interfaces and the like; downloading an xTEDS file, and accessing a plug and play node into the common bus; periodically polling and sending a broadcasting signal handshake frame through a satellite house-keeping computer; and after the IISD (Intelligent Interface for Spaceborne Device) of a new on-line device obtains a registration response, sending the xTEDS file to the satellite house-keeping computer to finish the registration of the spaceborne device/load, carrying out identification control on the new device/load, sending response information to the satellite house-keeping computer after the request inf
