Abstract
In order to achieve the accurate measurement of PLC of power line communication (PLC), module power and solve the inaccuracy in common power measuring instruments and the complexity in operation, a PLC module power measurement system is designed based on LabVIEW that is user-friendly, highly-operable and adjustable in sampling rate and sampling period.The operating principle of the measurement system is introduced and the algorithm is analyzed in detail.Meanwhile, a variety of systems for measurement are compared to prove the high efficiency and accuracy of the current system.The causes of large errors in different types of measuring systems are later discussed and the necessary conditions to ensure high precision and sensitivity are summarized.关键词
