A pneumatic experiment platform based on LabVIEW virtual simulation technology is developed. The whole platform consists of pneumatic loop system and LabVIEW test control system. The pneumatic loop system is designed and simulated according to the working principle of the air tank charging system. The LabVIEW test control system is designed and simulated according to the air pressure control principle of the air tank charging system. The switch value of the circuit adopts solid state relay, and the control program is written through LabVIEW as the virtual controller. The experimental platform has been put into use. Practice has proved that the experimental platform is easy to build, and the operation steps and knowledge points are easy to understand and master. It is suitable for mechanical majors to learn. Through programming control of pneumatic equipment, the interest and innovation of the experiment are increased, and the enthusiasm and initiative of students are mobilized.
