Design of phase measuring instrument based on FPGA and MCU
Abstract
With the continuous development of science and technology, phase measurement technology has been covered with scientific research, national defense, production, metallurgy and other industries. In order for the phase measurement technology to play a greater role, it is needed to continue to improve its measurement accuracy. The emergence of digital phase measuring instrument is no doubt the industry's feat, its wide range of applications due to its high accuracy of the measurement and a high degree of intelligence.
Firstly,the paper discusses the phase measuring instrument technical background, research significance and now in the domestic and foreign development.Secondly, from the aspects of the design theory, hardware structure and software design were analysis and design. This design by the combination of FPGA and MCU methods to achieve the accurate measurement of phase measuring instrument. In the characteristics of the CIMC FPGA design is rich in resources, fast operation, easy programming and MCU operation ability, strong ability to control. The whole design is pided into four modules: input module, data acquisition module, data processing module and display module, mainly using single-chip data to the FPGA to read, and according to the read data to calculate the measured signal frequency and phase difference. At the same time, the data function of FPGA can be converted, and the frequency and phase difference of two signals to be measured can be clearly displayed by the display module of single chip microcomputer. Finally with Quartus II as the operation platform, complete the design, compile, debug and simulation of the FPGA schematic module.
