The invention discloses a power consumption information acquisition terminal software comparing testing device and a method thereof. The device comprises an upper computer, a testing table, a local comparing testing device and a remote comparing testing device. The upper computer is connected with a tested power consumption information acquisition terminal mounted on the testing table through the local comparing testing device, or the upper computer is connected with the tested power consumption information acquisition terminal mounted on the testing table through the remote comparing testing device or directly connected with the tested power consumption information acquisition terminal. The local comparing testing device comprises a three-phase power source and a router. The three-phase power source is connected with the testing table and supplies working voltage with adjustable magnitude and adjustable working manner to the tested acquisition terminal. The remote comparing testing device comprises a communication frontend processor. The power consumption information acquisition terminal software testing device and the method thereof realize a multiple-meter-position mixed manner and can perform simultaneous controlling on a plurality of meter positions, thereby improving working efficiency, realizing comparing between a local end and a remote position, and realizing flexible application.
