Abstract:

A gas hydrate experimental apparatus generally has the characteristics of numerous test parameters and complex test process. It is necessary to develop measurement and control software to meet the high requirements of automatic operation of the experimental apparatus. Based on the analysis of the functional requirements of the software, a set of measurement and control software for the electrical-acoustic joint detection apparatus was developed with LabVIEW, using the ideas of modular and functional design in software engineering. The software includes start-up and login module, parameter setting module, signal generation module, multi-channel switching module, data acquisition and processing module, data display and storage module, error handling and help information module. Experiments show that the developed measurement and control software is characterized by strong expansibility and maintainability, simple and intuitive human-computer interface, high automation. The adverse effects of excessive manpower cost and manual participation on test results are avoided. The accuracy and reliability of the test results and the efficiency of the simulation tests are improved.
