Design And Implementation Of IOT Gateway

With the rapid development of the Internet of things technology,embedded systems are more widely used in the Internet of things technology,and the equipment also presents complex and diverse.The Internet of Things,as an important equipment to connect sensor network and traditional communication network,plays a vital role in the development of Internet of Things.However,the complexity and broadness of the network require the Internet of Things to have software and hardware requirements to adapt to the complex environment.To this end,this paper discusses a low-power,multi-function,multi-communication protocol gateway of the design and implementation of things.In this paper,the Internet of things operating system is embedded Linux,and the main hardware chip is TMS320DM365.It has completed the gateway system structures,and put forward the design requirements of network convergence.Firstly,according to the system requirements,this paper designs the hardware circuit,transplanted the Wi Fi driver,4G driver,transplants the Zig Bee and Bluetooth protocol stack,designs the network access point suitable for this gateway,and realizes the network access function of different network.Secondly,through the research of gateway application technology,the design structure of application layer software is put forward.By using the function division of the module,this paper designs the detailed communication software,and defined the data structure.At the same time,the protocol conversion between heterogeneous networks is realized.At last,the paper describes the testing method of the module of the gateway system and the method of capturing the data,analyzes the test results,and puts forward the improvement method for the problem.The results show that the Internet of Things system can meet the design requirements and achieve the expected results.
