The Research of HART Sensor System Based on ARM

Abstract:

This paper discusses the design method of economical and practical HART protocol communication system, and describes the research scheme in detail, according to the hierarchy of the system protocols: the physical layer, data link layer and application layer. This scheme includes the design of ARM embedded controller module, modulation and demodulation module and USB interface module and other components. According to the effect of the final product used in the field bus network, it is proved that the operation is stable, accurate, simple and easy.
