The invention provides an electric energy meter and acquisition terminal product operation live simulation device, a commercial power access part employs a two-stage transformer isolation design of afirst transformer and a second transformer, and is used for purifying commercial power and providing a clean 220V voltage for a rear stage; the input end of the terminal or the meter reading controller is connected to the output end of the mains supply access part, and the output end of the terminal or the meter reading controller is connected to a power line and used for injecting meter readingcommand information into the power line; a shielding box adopts an electromagnetic shielding shell; functional ports are reserved, the functional ports and the electromagnetic shielding shell are reinforced through a seamless process, a strong current attenuator is installed in the shielding box, the power line enters the shielding box through the line inlet port and is connected to the input endof the strong current attenuator, and the output end of the strong current attenuator is led out through the line outlet and then is connected to the single-phase electric energy meter access port andthe three-phase electric energy meter access port. Through the device, an electric power signal conduction influence mechanism can be deeply researched, and data support is provided for ubiquitous electric power Internet of Things construction.
