| Abstract: | Most Traditional transmitters adopt analog signals to realize communications between among various devices,and thus the power consumption is very huge.In this condition,signals are easily interfered.However,HART protocol could realize the transfer of digital signals over analog circuit.This paper presents the functions and features of HART protocol,including the hardware and software design of low power-consumption intelligent transmitter based on the HART protocol.Meanwhile,for the ultra-low power-consumpt... |
