Mechanical system includes mechanical structure design of exploring head, measuring and controlling box. Circuit system includes the least system of S3C44BOX automatic gathering system、 man- machine vision system、 circuital schematic diagram and PCB design of communications system. and completion of correlative function drive software.
Data accumulation and processing is carried out by a personal computer to which the data acquisition system is connected via an RS-232 channel and high-speed synchronous channel.
A data acquisition system containing up to four multichannel galvanically insulated modules capable of recording the shapes of single pulse signals is described.
This paper introduces the principles for pulse swallowing,the decimal frequency synthesismethod based on that and analyses its application in the 5386 Telmetry Seismic Data Acquization System.Thephase compensation for the decimel frequency synthesizer is discussed.A method of the phase compensation isanalysed which may be implemented by a system made of a microprocessor and a D/A converter'
The performance of the seismic data acquisition system function directlyon increaing amount of visibleinformation heightening resolution and quaranteeing highfidelitv of the seismic data.This paper discusses thesequestions and proposes a practicalstep to improve the performance.
This paper presented the design, performance feature and application results of Model MD-2 data acquisition system which was connected to the Quartz photoelectric variometer made in Russia.The data acquisition system for the variometer achived digitalized record at Beijing Geomagnetic Center Observatory.
