Design of Intelligent Transmitter Based on HART Protocol

In this paper, on the HART (Highway Addressable Remote Transducer) protocol and the system project gives a brief introduction, and then expatiates the hardware and software design of the intelligent transmitter based on HART protocol. Proposed a set of practical intelligent transmitter solution. The ultra-low-power consumption microcontroller is adopted as the control core of the system. The power consumption demand is considered continuously during device selection, circuit design and program design process. The system low power consumption design is realized, and meet the demand of the loop powered intelligent transmitter, while the system realized all of the common commands and part of the special commands of the HART protocol, matched the general characters of the HART intelligent transmitter.
