Abstract

In order to solve the problem of wide-range and high-precision angle measurement, a kind of grating-angle measurement system was designed. The grating sensor was used as output part of angle measurement signal, and the grating signal hardware decoding programme was designed applying CPLD, which achieved signal division and direction discerning and counting. The MSP430 MCU was used as control unit to achieve angle number calculation and display, communicating with CPLD by parallel bus. The design was verified its actual working effect by experiment tests, and the experiment data was finally analysized. The result showed that the system could reach 0.25mil measuring accuracy, working stably with quality of low-power and high-precision.
