Data acquisition system, control method, device and equipment thereof and medium

Abstract

The invention discloses a data acquisition system, a control method, device and equipment thereof and a medium, which are used for prolonging data acquisition time and data processing acquisition timeand realizing high-speed data acquisition. The data acquisition system comprises a signal transmission line, acquisition units, and a processing unit. The signal transmission line is connected with aplurality of signal delay units in series, and the output end of each signal delay unit forms an acquisition point; the acquisition units are in one-to-one correspondence with the signal delay units,and the acquisition units are connected with acquisition points of the signal delay units so as to acquire signals at the acquisition points between each pair of acquisition units and signal delay units which correspond to each other; and the processing unit is connected with the acquisition unit and is used for reading the signals acquired by the acquisition units.

Description

technical field [0001] The present invention relates to the field of data acquisition, in particular to a data acquisition system and its control method, device, equipment and medium. Background technique [0002] As data acquisition requires higher and higher speed performance indicators, high-speed data acquisition systems are widely used in automation control, electrical measurement, and aerospace engineering practice. [0003] A high-speed acquisition system is generally divided into two parts: data acquisition and data processing. During data acquisition, data will be collected at a high speed, and the collected data will be stored in the buffer. The processing unit will extract the data from the buffer for processing, and After processing the data collected last time, the control acquisition system collects data again. [0004] Since the speed of collecting data in the high-speed data acquisition system is very fast, and the cache time and storage capacity of the buff...

Problems solved by technology

[0005] And because the processing speed of the existing processing unit is limited, when the data processed by the processing unit is too much and the processing time of the processing unit is too long, a large amount of data collected last time is stored in the buffer, which makes it impossible to collect the next data, leaving The time for the next data collection is shortened

[0006] To sum up, the current data acquisition system, when collecting data at high speed, may have insufficient processing time and data acquisition time of the processing unit
