The invention relates to a broadband micro-power multi-network comprehensive test system for an electricity utilization information acquisition system, which belongs to the field of electricity utilization information acquisition of power consumers and comprises a system configuration module, a test case module, a data analysis module, a test report module, an adaptation module, an adjustable attenuator, a signal isolation box, a simulation ammeter module and a base. An external multi-network environment is built through the concentrator, the electric energy meter, the adjustable attenuator, the signal isolation box and the like, so that multi-level multi-network can be conveniently realized, and an actual application scene is met. In order to realize full coverage of a multi-network test, a plurality of communication modules are placed through a base, and an electric energy meter which is in one-to-one correspondence with the base communication module is simulated at a PC end, so that a tester can easily control a tested object, and the simulated electric energy meter can make up some processes that a real electric meter cannot be tested in a laboratory environment.
