| Abstract: | Realized the measurement of different physical quantities by serial communication.To solve precision problem of power when the power factor is lower,ATT7022 is used as the core to gather AC quantities to make the precision of real power meet 0.5 s and the one of reactive power meet the second-level.The optimization of test procedure makes the system finish parameter and characteristic measurement in a short time.Use median and arithmetic mean filters to do removal of the pulse and random disturbances.Adopt least square as the method of different characteristics fitting.The test results are identical to the theoretic analysis,which verifies feasibility of this system further.Research achievements can be popularized and applied to delivery test of the midand small-scale induction motor. |
| Keywords: | induction motor test system serial communication curve fitting |
