AI Technical Summary

Benefits of technology

This technology allows for simultaneously acquiring multiple channels with different frequencies from one another by creating a special circuit called a sample and hold (S&H) module. These modules help keep track on what has been captured accurately during processing while also improving image quality through enhanced sensitivity or increased dynamic range.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the speed and accuracy with which different types of analog or digital electrical devices communicate over networks such as wireless communications (WC), satellite broadcasts, space exploration missions, etc., particularly for applications that require real-time analysis capabilities like radio astronomy.

Abstract

The invention discloses a multipath data acquisition system, comprising a plurality of sensors, a plurality of amplifiers, multiple paths of analog switches, a sampling maintaining module, an A/D converter, a pre-processing unit, and an industrial personal computer; each sensor is connected to the corresponding amplifier; the amplifiers are connected to the multiple paths of analog switches; the multiple paths of analog switches are connected to the sampling maintaining module which is connected to the A/D converter; the A/D converter is connected to the pre-processing unit; and the pre-processing unit transmits data to the industrial personal computer. The multichannel synchronization data acquisition system can collect signals of various channels at the same moment and has high data collection efficiency. The arrangement of the sampling maintaining module guarantees that the digital signal converted through the A/D converter can accurately reflect the original simulation signal.
