The Method And Realization Of Plug And Play In The Platform Of Sensing And Control

In recent years, with the rapid development of computer and communication technology, Internet is growing at an alarming rate in the whole world, Internet technology has been widely penetrated into various fields. The network of virtual world has failed to meet the needs of people for intelligent life; the development of the Internet of things(IOT) has got the good opportunity. IOT as an extension of Internet, which is widely used in network convergence by using the intelligent perception, recognition technology and pervasive computing.It is also called the third wave of world information industry development after the computer and Internet.Firstly, this thesis does some research on the status of IOT at home and abroad, IOT involves too much technology and industry. At present, there are still no relevant standards, so relevant technical standards play an important role in the development of IOT. This thesis does some deep research on the platform of sensing and control, which realizes the method of plug and play, and illustrates the necessity and practical value of the study.Secondly, on the basis of analyzing the existing physical devices and virtual sensing data, this thesis abstracts them, then establishes processing and storage rules; and designs the adaptation totally, to make the sensor data access to the platform quickly.Moreover,this thesis researchs on the technology which used by the platform in each level, including the design of wireless networking global ID in the cognitive layer,the design of data frame format in the network layer and the design of data receiving module, processing module in the application layer.Finally, a simple platform system of sensing and control has been designed and accomplished, the sensing data which is sent by the sensors that have different standards, different technology, different sources, different format must be able to access to the platform, to achieve the effect of plug and play,and the platform can provide sensing service.
