Synchronous data acquisition system

Abstract

This paper describes a complex that implements synchronous data collection from geophysical equipment. It includes several blocks. Each of them, in turn, consists of a data acquisition unit and a micro-switch unit. The communication between the blocks is carried out using the UDP protocol over a twisted pair of category 5 EIA-568. The data transmission channel is used to power the system and transmit clock signals. The micro-switch unit transfers data from the data collection unit to the local processor. The data collection unit converts analog signals from target loads (magnetometer, geophone) into digital form. Also, this block can adjust the level of the analog signal. The article presents the architecture of the complex and the structure of each of the blocks, presents the results of measurements and notes the features of the operation of the complex.
