The invention provides an I-type power efficiency management terminal and system. The terminal comprises a terminal shell, a control unit, a power supply module, a storage unit, a data collecting module, a communication module and a display module, wherein the control unit is arranged in the terminal shell, and the power supply module, the storage unit, the data collecting module, the communication module and the display module are connected with the control unit. The data collecting module comprises a DC analog quantity collecting unit. The DC analog quantity collecting unit comprises two independent DC analog quantity sampling circuits and a DC analog quantity isolating circuit. The front ends of the DC analog quantity sampling circuits are provided with a TVS and a zener diode which are connected with current signals, a DC sampling resistor connected behind the TVS and the zener diode, and a dual-channel sampling and measuring chip connected with the DC sampling resistor. The I-type power efficiency management terminal comprises the DC analog quantity collecting unit, and therefore non-electric quantity information, namely, DC analog quantity data, such as flow, pressure, temperature and humidity detected through sensors can be collected, and then the electric power environment can be detected and managed.
