ABSTRACT

In order to improve the speed detection accuracy of coal mine belt motor, this paper introduces the principles of digital signal processor (DSP) and photoelectric encoder in detail, and designs the speed monitoring system of coal mine belt motor by using the internal orthogonal coding pulse unit module of DSP, with emphasis on the interface circuit between DSP and photoelectric encoder.
