Design And Implementation Of Sensing Devices' Driving Frame In IOT

IOT,the Internet of Things is the Internet conecting things and things.It can also be considered as a extension of the Internet.The development of IOT is no doubt the hottest area of researching and applying.When it comes to the development of an IOT application,the sensing devices'accessing to IOT is a very improtant thing.As usual,most sensing device's driver provided by manufacturer are different.They do not follow the same API standard and have a limit on the operation system.But the development of IOT needs a lot of sensing devices,it is unrealistic to develop an adapting program and provide a operation system environment every time.So it is necessory to design and develop a sensing devices' driving frame.With driving program frame,the devices' manufacturer and the driving programers can write codes more efficient,based on the structure and driver model mentioned by the driving frame.And the codes will have a clearer structure.The reusability,the transplantability and the quality of the codes will be greetly improved.In this paper,I designed a sensing devices' driving frame,which adapted to the IOT environment,and a efficient devices accessing method combined with my graduated work after the research of Windows CE and Linux driving program frame.The details are as follows:First this paper analyzed Windows CE and Linux driving program frame.Windows CE and Linux are two of the most popular embedded operation system.And the accessing layer of the IOT is realized by IOT gateway.So it is very meaningful to analyze the two driving program frame.Then this paper designed a sensing devices' driving frame in IOT.Refered to the advantages of the two driving program frame,and conbined with the IOT environment,this paper designed a layered driving frame,which divided the driving program into hardware driver and adapting program,and designed a driving model.This paper also designed a unified APIs according to the types of the sensing devices which greatfully helped the developing of driving programs and the accessing of the sensing devices.After that,this paper designed a efficient sensing devices' adapting method in IOT.In order to helping the realizing of the sensing devices'driving frame,combined with project experience,this paper desined a efficient sensing devices' adapting method.The core of the method is the adapting programs' autogeneration in according to the actual conditions,and the efficient accessing flow.At last,this paper use RFID and sensor to verify the usability and realized the sensing devices' driving frame.On the basis of the research and design,this paper verified the suability by access a RFID and sensor device.Then the paper also realized a patrol system based on the sensing devices' driving frame,the efficient adapting method and an IOT platform,which proved the feasibility of the plan.
