Research And Development Of Power Distribution Equipment Condition Monitoring System Based On Restful Web Service

Power distribution equipment condition monitoring is the basis work for power distribution equipment condition evaluation and condition maintenance.The power distribution equipment condition monitoring is referring to collect and upload the operational data of the field equipment to primary platform based on the information and communication technology.The online monitoring of the operational status of power distribution equipment is provided by analyzing,storing and processing the data to ensure the power distribution equipment safety and stable.At present,the power distribution equipment condition monitoring is still in its infancy and development stage.There are relatively few researchs and applications in power distribution equipment condition monitoring,in which most of the application scenarios are concentrated in power grid enter:prises rather than the user side scene such as the campus,industrial park and community.The thesis is based on the power distribution equipment condition monitoring system.It introduces the Internet of Things technology into the research and design of the system.In view of the problems existing in the longterm use of SOAP protocol to build a web application,the difference of two ways to implement web services,including the rmote procedure call(RPC)based web services and resource oriented architecture(ROA)based RESTful web services are discussed and compaired in technical characteristics,distribution equipment condition monitoring system basdevelopment trends and service performance.The overall architecture of power ed on RESTful web service is proposed because of its advantages in building a lightweight web application.Besides the system database and data interfaces are designed at the same time.The data acquisition and communication scheme of the system substation platform is elaborated,and the pre-analysis of the operation data of the power distribution equipment is realized based on the Modbus communication protocol.A single page web application of power distribution equipment condition monitoring system pr:imary platform is developed by the way of front-end separation when the development integration and deployment of the projects is explained.The power distribution equipment condition monitoring system proposed and developed in the thesis is combined with the implementation of a smart campus power distribution system capacity expansion project,which can provide panoramic monitoring,operation monitoring,asset management and other functions for power distribution equipment within the campus,which constitutes a typical"Internet of Things + Smart Campus"application.
