| Abstract: | The basic principle of testing cable faults with narrow-pulse equidistance sampling is described.Pulse characteristics and processing requirements are analyzed.The single-line repeated low-speed data acquisition system is designed with FPGA and MSP430F149 as main control chips.Main control procedures are programmed in Quartus II and simulated in Modelsim.Experimental result shows that the system is practical,and the problem of high-precision data acquisition in the process of cable fault location is resolve... |
