Research and Design of Intelligent Wireless Power Parameter Detection System

To assure electric power system and used in safe state, we urgent need to monitor, analyze, and measure various electric power parameter, which can provide rectifying and reforming scheme effectively, strength preventive measures, and assure electric power operation in safety, reliable, and economic. SO, electric parameter monitoring technology emerges. Aiming to disadvantages of present electric parameter monitoring, we design a kind of wireless power electric parameter detection system based on single chip microprocessor (SCM) technology, wireless communication technology, and visual instrument (VI) technology, etc. System is composed of upper PC and lower PC, lower PC module acts SCM as core of processor, and uses voltage/currency transformer module, signal processor module to realize electric network signal conversion, which can be recognized by MSP430F149 and completes signal A/D transfer by itself ADC12 module, as well as controls nRF905 wireless transceiver module to realize signal transmitting between lower PC and upper PC's wireless receiving module in real time. Wireless receiving module is connected with Upper PC installing of LabVIEW through serial interface RS-232, which power electric parameter detection system is carried out. This paper mainly introduces system's structure, part of hardware and software design in detail.
