Design And Implementation Of Distributed Power Measurement System

With the development of industry, in the production process, often need to measurecurrent and voltage at the same time more than one motor is within the normal operatingrange, often due to staffing problems, collect consumption data difficult. Thus, the need todesign both the test multiple motors, but also at the same time collecting intelligence testinstrument data. Distributed power measurement system application and Health, theinstrument has a number of detection module, capable of simultaneously measuring multiplecircuits, each detector through a wireless transmitter module communicate with the host, sothe host control multiple detection module, to break barriers of time and some space. Toachieve the same motor data acquisition requirements in different locations in the same pointin time.Design of this project is a distributed power measurement system, which uses the powermeasurement module, memory module, wireless transmission module and control chips.When the sampling probe distributed power wireless measurement system operation, thetransformer collected current and voltage signals into electric energy metering chipATT7022B processing, control chip for processing the input data via the serial interface SPIchip metering data read out, thereby completing the measurement function according to needfor communication transmitted through the wireless communication module, themicroprocessor module via the wireless transmission of the signal transmitted to thecollection host, the host treated, the display screen shows the operation of the data acquisitionis completed and monitoring parameters, record store various data. Finally, the basicfunctions of distributed power measurement system, the experimental results show that thedesign of the instrument standard measuring instruments.Distributed power measurement system with multiple measuring points wereindependent sampling, analog-to-digital conversion, the distributed features for PV grid-connected inverter performance tests also have a good effect.
