摘要：Each item of sensory information is effectively integrated by Internet of things (IoT) system. However, due to different framework and interface, software and hardware platform and communication protocol are mutually independent, which makes distributed IoT system unable to fulfill uniform operation and management. By aiming at issues difficultly fulfilled by IoT system, a kind of framework model of IoT system based on Web Service is put forward. Firstly, function and framework analysis is conducted for local sensor service system, integrated sensor service system and integrated application service system required by model; next, an introduction about design of Web Service interface is made; finally, services and functions are abstracted to normalize the relation among three varieties of service systems of model. This scheme is proved to be with good applicability, flexibility and expansibility in cases.
