The invention provides a graphical interface generating method for an embedded supervisory control and data acquisition (SCADA) system. The method comprises the following steps of: designing a graphical interface of the SCADA system in a personal computer (PC) machine by using a graphical interface development tool, generating a graphical interface file, transmitting the graphical interface file to the embedded SCADA system through a communication interface, and transmitting the graphical interface file to a corresponding interface processing module through a corresponding protocol template; establishing an information point table template, and establishing a memory bank according to the information point table template; and transmitting data in the memory bank and data processed by the interface processing module to a graphical adapter through a memory bank interface, associating the graphical interface data and the data in the memory bank by the graphical adapter, and thus generating the graphical interface of the embedded SCADA system. By establishing the protocol template and the information point table template, multi-device, multi-medium and multi-protocol device interconnection and integration can be easily realized, and the interface is generated only by simple interface configuration; and the development period is greatly shortened, the development cost is greatly reduced, and stability, reliability and robustness are greatly improved.
