| Abstract: | To solve the long-distance transmission problem of data acquisition system,a kind of tele-acquisition system for current data with semiconducting magnetoresistive current sensor(MRCS) and PLC-chip LM1893 is introduced.Its hardware circuit is mainly constituted by three units: AT89C2051 single-chip microcomputer control unit,data acquisition unit and LM1893 Power-Line-Carrier transmission unit.Its software is programmed with MCS-51 assemble language,and the flow chart of software design is also given.With the application of the Power-Line-Carrier(PLC) technology,the system is suitable for the measurement and transmission of remote signal,and has high practicality. |
