The diversity of sensor interface makes a lot of trouble for integration and maintenance of sensor application systems.It was particularly important to open and unify of the sensor interface.Based on research in sensor interface standard,it was discussed how sensor application system supports sensor interface standard.For sensor standardized interface module,an application platform was designed and implemented based on.NET.The platform can identify,configure and calibrate standardized interface module and test sensor data function.The experiment results illustrate the platform can effectively support application integrity of standardized interface module,interchange and plug-and-play of sensors.
