Design of Mine-used Signal Converter Based on HART Transducer

The paper introduced hardware and software design of a mine-used signal converter based on HART transducer. The converter takes C8051F040 single-chip microcomputer as central processor, which achieves communication with sensors with HART transducer and can display measured signal of sensor through digital tube, and has functions of range set, alarm value set, frequency output and CAN bus output.
