Application of FPGA in motor speed measurement
Abstract
This topic design is the application of FPGA in the motor speed, the Quartus II software as a platform, using Verilog HDL language and schematic diagram design, the 7 bit digital tube display function of dynamic circuit can be realized. The design of the system can measuring the amount of the speed signal, and carries on the analysis regarding this, and obtains a motor speed results through the operation part, through the digital tube display. The design principle of FPGA as the core by FPGA chip as the carrier, through the design method of software programming, simplify the hardware circuit design, the hardware circuits are integrated in FPGA The chip, the hardware circuit of a highly integrated. Through the software on the design of the logic circuit, the logic circuit is composed of a specific function of a combinational logic circuit can be achieved compiling the final simulation, download the test. Consistent with the goals of the design results and ideas, and the system is running stable, high reliability, easy to use.
At the same time, this paper also introduces the process of FPGA of domestic and foreign research status, working principle, structure, function and features a brief introduction to the photoelectric encoder and the principle of photoelectric coupler, Quartus II software design process. Design process includes the acquisition of motor signal, then the signal acquisition is doubled, learning to count, latch, operations, decoding display, finally found the data through the digital tube dynamic display.
The paper has 29figures, 29 references.
Key words: FPGA motor speed dynamic display digital tube
