Abstract

Aiming at remote visualization measurement problem of multiphase flow

an industrial electrical resistance tomography（ ERT） system with remote high-speed communication function is designed. The system uses optical fiber high-speed transmission to connect field unit and main control unit

by designing fiber-optic transceiver circuit and high-speed transmission protocol logic

high-speed remote communication function is realized. Through circuit design of serial acquisition scheme in field unit

structure of system is more compact and reliable. Through FPGA digital signal processing and logic design of asynchronous cache

remote data acquisition of system is more complete and accurate. System performance is verified throug

h test experiment and image reconstruction

transmission rate of optical fiber is 625 Mbps and bit error rate is lower than 10

-12

measurement repeatability and imaging rate of system meets industrial application requirement

and the system has remote visualization measurement function.
