Abstract

The invention provides a multi-channel temperature and stress-strain online measurement integrated system, which includes a data acquisition module with multiple data acquisition boards for simultaneously collecting temperature and stress-strain data signals of parts to be measured; a data processing module for Control the switching of the data acquisition of the data acquisition board, simultaneously receive the temperature and stress and strain data of the corresponding switched data acquisition board, and preprocess the collected multi-channel temperature and stress data; the calculation processing platform is used for the preprocessing The temperature and stress and strain data are analyzed, calculated, judged and warned, and control commands are sent to the data processing module, so that the data processing module can switch and switch the data collection module for the data collection module. The present invention can simultaneously / separately carry out temperature and strain data collection, analysis, calculation, display, storage and various control functions online, and analyze the temperature field and stress state through data analysis and calculation.

Description

technical field [0001] The invention relates to the technical field of temperature and stress-strain measurement and monitoring integration, in particular to a multi-channel temperature and stress-strain online measurement integration system and method. Background technique [0002] In the process of industrial production, it is often necessary to measure, monitor and record process parameters such as temperature, stress and strain. During the welding process, the welding temperature field and welding stress and strain directly affect the product quality. [0003] There are a wide variety of conventional temperature measuring equipment on the market, such as thermometers, temperature measuring pens, thermocouples, thermistors, infrared rays and other sensors for temperature measurement. Thermocouple temperature measurement is a temperature measurement method with simple structure, economy and convenience, and a complete range of models. It is widely used in welding, metal p...
