Research And Implementation Of Attribute-based Cryptosystem Based On Outsourcing

In order to speed up the construction of new energy,realize the unified operation monitoring,unified dispatching command,unified data management of photovoltaic power station,realize the small number of people on duty and unattended,master the operation status information of photovoltaic power station equipment,guarantee the safety of equipment,and improve the remote control ability of photovoltaic power station operation,a unified intelligent platform is urgently needed.Considering a large number of components and equipment in the photovoltaic power station,the photovoltaic power station needs to conduct real-time monitoring on the surrounding environment,and troubleshooting can only be carried out manually.In the specific environment of the power station,due to the limitation of space and time,it is very difficult to carry out all kinds of work.This thesis analyzes and investigates this,develops and designs the operation and maintenance platform of the photovoltaic power station equipment,and carries out unified management.Its main functional modules include: equipment information module,operation and maintenance information module,fault management module and maintenance and repair module.Equipment information is mainly for the unified management of all components of photovoltaic power station,not only for the management of various parameters and the number of components generated by components,but also for the real-time display of the operation status of components;operation and maintenance information module is mainly some non component information,including user information,basic information of power station,environmental information and electricity information;The intelligent early warning algorithm is used in the fault management module,which can not only monitor the fault of battery and power station,the maintenance and repair module can view the historical maintenance records and the maintenance application.Due to the large number of components and devices in photovoltaic power station,the amount of data generated is various,and the data format is different,so it is necessary to collect data from different devices.After data collection,it needs to be transmitted to the data center through the network.The data center analyzes and processes a series of data,and finally displays it in the interface in real time.Starting from all the functions of the operation and maintenance platform of photovoltaic powerplant equipment,this paper adopts the MVC design mode to separate the model layer,view layer and control layer of the platform,which not only reduces the cost budget,but also improves the scalability of the platform.Once the demand of the power plant changes,the system functions can be adjusted in time.
