The invention discloses a dual mode heterogeneous local communication unit module performance detection system, which comprises an industrial computer, an integrated tester, a multi-function electromagnetic wave chamber, a V-type artificial power network and two standard protocol signal sources. The integrated tester, the multi-function electromagnetic wave chamber, the V-type artificial power network and the two standard protocol signal sources are all connected with the industrial computer respectively. The multi-function electromagnetic wave chamber, the integrated tester and the V-type artificial power network are networked. And the integrated tester is connected with the two standard protocol signal sources through a first single-pole-double-throw switch. The dual-model heterogeneous local communication unit module performance detection system adopts a virtualized tool testing mode, provides a standardized testing environment, and can test the radio frequency performance, the protocol consistency and the performance of a carrier wave. The entire system, in strict accordance with the industrial or national power grid standards and norms, ensures the reliability and stability of testing results. The modular and structural designs achieve not only automatic testing, but also facilitate the installation and maintenance of the system, therefore, greatly reducing the difficulty with operations while increasing the use convenience.
