Abstract:

Aiming at the problem of test procedures low degree of automation and pulse countings bad accuracy, this paper adopts the technology of finite state machine and realizes the function of threshold filter on FPGA platform, and uses direct pulse counting method and FIFO storage technology, solving the problem of pulse counting and inconformity of transmission rate inside measuring system. Adopting the technology of virtual instrument, the paper realizes the function of automatic data processing on the LabVIEW platform. Going through the experimental verification, the measuring system can make true that pulse counting, controlling the error of pulse counting within  . And achieving automatic data processing, the design can improve the degree of automation of measuring system.
