Abstract

The invention relates to the field of experiment detection equipment, in particular to a distributed data acquisition system and a distributed data acquisition method suitable for large-scale multi-field coupling test equipment. The distributed data acquisition system comprises a main control system and a plurality of sensor sub-modules with different functions, wherein hardware of each sensor sub-module is connected with the main control system by means of a gateway module. The distributed data acquisition method comprises the steps of: classifying the sensor sub-modules with different functions into four types according to the conditions of an upper computer software development language type of each sub-module, whether a source code is opened or not and whether a sub-module sensor reading and control system supports command standard of a program control instrument or not; and additionally arranging a data reading and control interface matched with each type of sensor sub-module in the sensor sub-module according to the characteristics of each type of sensor sub-module, and additionally arranging a corresponding data communication interface in software of a main control system torealize data exchange. The distributed data acquisition system and the distributed data acquisition method have the advantages when more sensor sub-modules with different functions are researched, developed, changed/increased or decreased in an equipment system, and facilitate the unification of data formats of transmission, processing and storage of multi-sensor data.

Description

technical field [0001] The invention relates to the technical field of multi-sensor test equipment, in particular to a distributed data acquisition system and method in large-scale multi-field coupling test equipment. Background technique [0002] Multi-field coupling test equipment in large-scale engineering, especially civil engineering, needs to comprehensively monitor multiple parameters such as temperature, moisture, salinity, stress, and strain in geological open systems. The joint action mechanism of the effects is supported by a large amount of data. It plays an important role in deeply understanding the causes of geological disasters and improving the prevention and control system. At present, advanced engineering multi-field coupling test equipment and related technologies have become one of the major needs of the country. [0003] In the prior art, a large-scale soil boundary value method is currently a feasible test method, that is, arranging more sensors of di...
