The utility model relates to a portable water pump test system, which belongs to the technical field of automation measurement and control. An industrial computer USB (universal serial bus) serial port is connected with an RS485 external bus for realizing the wireless communication, and the intelligent measurement and control of a three-phase alternating current motor can be realized. The portable water pump test system comprises a parameter detection unit, a direct current resistance measuring unit, an intelligent control unit, a virtual instrument display unit and a control early warning unit, wherein the intelligent control unit is a computer, an external bus of the intelligent control unit is communicated with the intelligent instrument respectively connected with the parameter detection unit and the control early warning unit, the virtual instrument display unit schematizes an instrument to an industrial computer display screen, and various kinds of sensors and various kinds of test instruments of the parameter detection unit, and RS485 communication interface chips are sequentially connected. The portable water pump test system has the advantages that each signal type can be collected and displayed by the instrument, the test requirement can be met, the real-time monitoring on the motor can be realized, and the real-time and effective protection can be realized on the current, the voltage and the temperature of the motor.
