Data processing system suitable for thermal power plant multi-protocol data acquisition and data write-back

The invention discloses a data processing system suitable for multi-protocol data acquisition and data write-back of a thermal power plant, and the system comprises a protocol converter module which is used for converting a standard industrial protocol of a production system into a message protocol in a unified subscription publishing mode; the real-time data collected from the production system is sent to the data gateway module, and the write-back data received from the data gateway module is sent to the production system; the data gateway module is used for receiving the real-time data sent by the protocol converter module and storing the real-time data to a specific position of the tree structure database; receiving a data value sent by a third-party application, acquiring write-back data according to the data value, and sending the write-back data to the protocol converter module; and the tree structure database is used for storing real-time data. The data processing system provided by the invention real
