A universal virtual experiment real object equipment access system comprises a hardware interface protocol converter, a virtual experiment proxy node and a configurable automatic real object equipment access gateway generator. The hardware interface protocol converter comprises a protocol conversion unit and a bus interface. The universal virtual experiment real object equipment access system has the advantages that on the basis of user software interface configuration, a virtual experiment access gateway matched with a real object equipment transmission protocol is automatically generated, the heterogeneity problem of the transmission protocols and the transmission interface is solved, and rapid and seamless linkage of real object equipment and virtual equipment middleware is achieved. According to the universal virtual experiment real object equipment access system, on the basis of flexible protocol configuration, rapid and seamless integration of a real object virtual experiment verification platform is achieved, the heterogeneity problem of the various transmission protocols is solved, user zero-code compiling is achieved, and the development period of the virtual experiment verification application is shortened.
