A DSA composite operating room intelligent control system comprises a center server, a network switch, a DSA image data collecting subsystem, an operating room rebroadcasting / showing subsystem, an operating room environment monitoring subsystem and an operating room equipment control subsystem. The center server is connected with the DSA image data collecting subsystem, the operating room rebroadcasting / showing subsystem, the operating room environment monitoring subsystem and the operating room equipment control subsystem through the network switch respectively. The technical problems that information resources of a traditional medical teaching system cannot be stored in a unifying mode, and operation long-distance showing and medical image concentrating displaying cannot be achieved are solved, system interactivity is greatly improved, accordingly, real-time dynamic cooperating is achieved, the functions such as long-distance showing and digital image transmission are achieved, and high-quality transmission of high-definition digitization images between an operation image rebroadcasting system, a teaching system, an academic report communication system and a specialist consultation system is achieved.
