Abstract

The invention relates to the field of experimental detection equipment, a distributed data acquisition system and method suitable for large-scale multi-field coupling test equipment, which consists of a main control system and a variety of sensor sub-modules with different functions, and each sensor sub-module hardware passes The gateway module is connected with the main control system. According to the language type of the host computer software development of each sub-module, whether it is open source code and whether the sub-module sensor reading and control system supports the program-controlled instrument command standard, the sensor sub-modules with different functions are classified into 4 types; The characteristics of the sensor-like sub-module add a matching data reading and control interface to it, and add a corresponding data communication interface in the software of the main control system to realize data exchange. It has advantages when developing, changing / adding or removing more sensor sub-modules with different functions in the equipment system, and it is also convenient to unify the data format for the transmission, processing and storage of multi-sensor data.

Description

[0001] The invention relates to the technical field of multi-sensor test equipment, in particular to a distributed data acquisition system and method for 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 different types in t...
