High -precision synchronization collection system

TL;DR: In this article, a high-precision synchronization collection system for telecommunication is presented, including voltage transformer for voltage signal insertion before the ammeter samples, current transformer for current signal insertion, gear shift control and signal conditioning module for the signal of having sampled to voltage transformer and current transformer carries out automatic gain control, filtering and enlargies.

Abstract: The utility model discloses a high -precision synchronization collection system, including voltage transformer for voltage signal to inserting before the ammeter samples, current transformer for current signal to inserting before the ammeter is sampled, gear shift control and signal conditioning module for the signal of having sampled to voltage transformer and current transformer carries out automatic gain control, filtering and enlargies, the AD chip for the signal of having sampled to voltage transformer and current transformer carries out analog -to -digital conversion, and the data signal that will change conveys to FPGA and handles, the utility model discloses the signal bell of gathering has time mark information, has realized the synchronous high accuracy collection of the signal of telecommunication, through working voltage, current transformer, has guaranteed the sampling precision of installing, has guaranteed simultaneously that forceful electric power and light current separate totally, the outside electromagnetic interference that significantly reduces, the reliability and the security that have improved the device, and these information not only can be in the proscenium realtime application, also can baling sends and carries out various application and assay for the backstage
