Abstract: This paper described the development platform of testing system for geotextiles by using VB and neuro-fuzzy algorithm,and elucidates the design idea and model with focuses on the software and hardware for testing,establishing data bank,network security and driving fuzzy-logic controller et al.An exemplum is given of testing the volume of water flow on a given plane of geotextiles.It is proved that the development platform helps the intellectualization and networking of testing instruments for geotextile and shortening their design cycle.It has better practical value.
