The utility model provides a 1-type electric power efficiency management terminal and a system. The terminal comprises a terminal housing and a control unit arranged in the terminal housing. The terminal also comprises a power supply module, a memory unit, a data acquisition module, a communication module and a display module which are separately connected to the control unit. The data acquisition module comprises a direct current analog quantity acquisition unit which further comprises two direct current analog quantity sampling circuits which are independent from each other and a direct current analog quantity isolation circuit. The front end of the direct current analog quantity sampling circuit comprises a TVS and a zener diode in signal connection with currents. The front end of the direct current analog quantity sampling circuit further comprises a direct current sampling resistor which is connected behind the TVS and the zener diode and a binary channel sampling measurement chip connected to the direct current sampling resistor. The 1-type electric power efficiency management terminal is with the direct current analog quantity acquisition unit which can carry out acquisition on non-electricity quantity (such as the flow, the pressure, the temperature and the humidity) information (i.e., direct current analog quantity data) detected by sensors so as to realize detection and management of electric power environments.
