The utility model relates to an intelligent measurement and control system for a three-phase AC motor, belongs to the technical field of automated monitoring, and particularly relates to the monitoring of the working condition of the three-phase AC motor. In the measurement and control system, an industrial computer USB serial port and a MODBUS communication protocol are employed, the computer serial port achieves communication with and control to an intelligent detection instrument and a control early warning unit which are respectively provided with an RS485 series interface chip of a wireless communication chip through an RS485 external bus, and intelligent measurement and control of the three-phase AC motor is achieved. The intelligent measurement and control system for the three-phase AC motor comprises a parameter detection unit, a DC resistor measurement unit, an intelligent control unit, a virtual instrument display element and the control early warning unit; and the virtual instrument display element makes the instruments of the parameter detection unit and the control early warning unit graphical and graphical instruments are displayed on an industrial control computer display screen. The DC resistor measurement unit is connected with an A phase, a B phase and a C phase of the three-phase AC motor, a reliable strong/weak electrical isolation technology is employed, and automatic measurement of a motor DC resistor is achieved.
