Embodiment 1
[0026] Such as figure 1 and image 3 As shown, this embodiment includes: a device power consumption acquisition device with multiple interfaces, including: several interfaces arranged on a circuit board connected to the sampling amplifier circuit through the sampling signal line, connected to the output terminal of the sampling amplifier circuit An oscilloscope and a microcontroller connected to the interface through a data control line, wherein: a relay is provided between the interface and the sampling amplifier circuit to output the analog signal information from the interface to the sampling amplifier circuit, and a GPIO port of the microcontroller It is connected to the gate of the isolation MOS transistor, and the GPIO port of the microcontroller controls the isolation MOS transistor to be turned on and off. The drain of the isolation MOS transistor is connected to the first ground line, and the source is connected to the second ground line.
[0027] The interface is us...
