Exploration of Sensor Experiment Based on Virtual Instrument Technology

Taking the "sensor" experiment as the starting point, this paper introduces the use of virtual instrument technology to build an experimental platform and software design for electronic course experiments. It includes the sensor experiment, electronic circuit experiment and the operation interface of simulation experiment developed by virtual instrument technology. The experiments are divided into virtual and real combination experiments and virtual simulation experiments. The platform has functions such as automatic data collection, data storage, data processing, rapid curve drawing, automatic generation of experimental reports, and click-to-send emails. The optical fiber sensor experiment, frequency characteristic experiment and PID DC motor speed control experiment were carried out using the platform. The results show that the experiment is automated, paperless, and networked, creating a "student-centered" teaching platform, allowing students to have more time. Self-directed learning; experimental resources are networked, and experimental reports are standardized, which solves the problem of insufficient expensive experimental resources and improves the work efficiency of experimental teachers.
