Design And Implementation Of Open IoT System Architecture Based On Microservice

With the rapid development of the current software architecture and the rapid improvement of computing capability,IoT has the necessary development foundation,especially for the open-IoT system architecture.At present,the micro-service architecture is a more advanced software architecture design,and the core design of its architecture is the modular design of the whole system according to the business function.Each module completes the same type of business function.The module has the characteristics of high cohesion and low coupling,which can be used in a completely different technology stack to achieve business function,and the business interaction between modules is done by a unified interface call.This paper is based on the design of micro-service and developed a system platform,which can complete access and adapt to various types of independent IoT system.To achieve the unified management and control of the material networking equipment for the access system platform.The main work is as follows:Research aspects of platform modules,this paper analyzes the access and management of the Internet of things,and abstracts the most critical equipment access,equipment management and capability registry module in this system.According to the function requirements of the open Internet of things,each sub module of the above modules is implemented,including the rule engine,timing database and other modules in the device access module,and the device group management,authorization check and capability evaluation module in the device management module.The mechanism of a variety of device access protocols is studied,and the support of the device access module to a variety of equipment access protocols is realized based on the Netty and the Spring framework.Research aspects of algorithm,the negotiation and selection model of multi object common ability is studied and designed.The shortcomings and shortcomings of traditional QoS based capability selection mechanism are analyzed.A parallel negotiation based capacity selection model and corresponding simple negotiation strategy are put forward.The algorithm of equipment capability evaluation is studied and designed,and a hierarchical structure model is proposed for equipment capability.Based on the weight value of evaluation index,the Cost value of equipment capacity is calculated,and the evaluation value of equipment capability is obtained.Access equipment,laboratory equipment Home Furnishing existing intelligent system based on the completion of third party system equipment and the system's adaptation of access to work,in the process of the adaptation middleware technology for third party system equipment data acquisition and intelligent control.
