The Research And Design Of Networked Smart Sensors General Platform

With the continuous development of computer technology, communication technology, electronic technology and other related technologies, the Internet of Things (the Internet of Things, IOT) will be a clear direction of development of the IT industry in the new era with the challenges. Based on the Internet, it expands the scope of mutual communication, and implement free communication between matters. Internet of Things architecture from bottom to up can be divided into four layers:the perception layer, network layer, intelligent data processing layer and application layer. Sensor interface standardization and openness requirements of the perception layer that will be an urgent problem to breakthrough. This paper focuses a series of studies in networking smart sensor platform based on key technologies of the Internet of Things.Around the Internet of Things, introduces the concept of Internet of Things, the general architecture and key technologies, and research background and development in the world; Research sensors "intelligent" key technologies and implementation methods, focus on LMS-based adaptive filter algorithms and PCA-based multivariate linear regression data fusion algorithms, and implement MATLAB simulation; the need for standardization of sensor interface, open and standardized interface module design ideas based on the IEEE1451series of standards; In accordance with the design ideas of modularity and versatility, the paper gives the design of the sensor platform based on Internet of Things, respectively, from hardware and software of the smart transducer interface module (STIM) and network processor (NCAP) design.In the end, this paper carry out part of the testing of the sensor platform and application experiments, using the idea of hardware and software collaborative testing to verify the reliability and applicability of the platform. Give the applications of the platform to facilitate the use of the user and secondary development.
