Study And Implementation Of Intelligent Management System For Community Water Supply Based On Iot

With the arrival of Internet of things,different kinds of sensors and intelligent hardwares have been widely used in many areas such as medical health and industrial production,which prompts an increasing number of applications combinding the traditional information system with the smart hardware device.In the existing application development way,the high coupling of the communication with different devices and the business codes makes the application development and maintaince have more cost and complexity.In addition,existing applications regarding smart devices as discrete individuals rely much on the operators to manually monitor,analysis,make decisions and get feedback from information collecetted from devices.This way of operation will not only spend a lot of human resource but also take the risk of failing to respond timely to various events.Therefore,how to implement the flexible and loosely coupled device integration and provide support for intelligent operation,becomes a big challenge faced with during the development of application.To solve these problems,considering the specific case of the secondary water supply in the residential community,this paper proposes an intelligent water supply system for smart equipments.We generate RESTful services according to smart devices,then dynamically bind business functions with device operations through a flexible combination of device services,present the model description of the secondary water supply scenario and finally implement the perception and process of events based on ECA rules,to provide support for the operation of secondary water supply for the community.The main researches are as follow:(1)Proposing the overall frameworkThis paper proposes overall design of intelligent water supply management system,involving the equipment access and interactive,scenario modeling and event respond handling,which not only helps to rapidly develop application,but also provides support for intelligent management.(2)Presenting the method of equipment-oriented service combinationThis paper proposes the method of smart equipment-oriented service combination.For those devices interacting by OPC,we generate RESTful service interfaces for data and operation resources of devices,and then use mashup to achieve service flexible combination,making developers pay more attention on business logic in application layer,to effectively improve the flexibility of development.(3)Proposing the management of secondary water supply scenarioThis paper provides the complete model description for structures,devices and states in secondary water supply scenario,which combines discrete resources together.We also propose rule driven event handling mechanism based on ECA rules so as to find,judge and deal with events,to implement the intelligent management.(4)Implementing and verifying the prototype systemThis paper designs and implements the prototype system for smart water management,to provide effective support for device management,device and state monitoring,information statistics.The prototype system uses B/S architecture,uses Java to develop the server and uses HTML+JavaScript to develop the website.To summarize,this paper researches on intelligent water supply system in community,designs and implements the prototype system,and verifies the validity by applying it to the case of a community of secondary water supply.
