Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The cloud-edge cooperative management and control system for the power distribution network according to the embodiment of the invention is described below with reference to the accompanying drawings.
In an embodiment, a cloud-side collaborative management and control system of a power distribution network is provided, and as shown in fig. 1, the cloud-side collaborative management and control system of the power distribution network may include: the system comprises an internet of things management platform 10, an edge internet of things agent device 20 and a service terminal 30. The edge internet of things agent device 20 performs data interaction with the internet of things management platform 10 and the service terminal 30 by using a RESTful technology and an SNMP technology to manage the service terminal 30 in cooperation with the internet of things management platform 10, and manages and schedules the whole resources of the cloud-side cooperation management and control system by using an Openflow technology.
Specifically, the management platform 10 of the internet of things may also be referred to as a cloud platform, and since cloud computing is good at global, non-real-time, and long-period big data processing and analysis, and can play an advantage in the fields of long-period maintenance, service decision support, and the like, the cloud computing is applied to the management platform 10 of the internet of things to remotely control a service terminal. The edge calculation is suitable for processing and analyzing local, real-time and short-period data, so that real-time intelligent decision and execution of local services can be well supported, and therefore the edge calculation is applied to the edge internet of things agent device 20 to perform local management and control on service terminals. In addition, the internet of things management platform 10 and the edge internet of things agent device 20 cooperate closely to achieve cooperative management and control of the service terminal 30, for example, in order to reduce the pressure on transmission bandwidth and transmission cost, edge computing in the edge internet of things agent device 20 filters and cleans original data and then transmits the filtered and cleaned original data to the internet of things management platform 10 to complete further processing, so that a cooperative manner of "global optimization based on cloud computing + local optimization based on edge computing" is formed.
In cloud-side cooperative management and control, the edge internet of things agent device 20 performs data interaction with the internet of things management platform 10 and the service terminal 30 by using a RESTful technology and an SNMP technology to manage the service terminal 30 in cooperation with the internet of things management platform 10, that is, the internet of things management platform 10 manages the service terminal 30 by using the RESTful technology and the SNMP technology in cooperation with the edge internet of things agent device 20, and meanwhile, the edge internet of things agent device 20 manages and schedules the whole resources of the cloud-side cooperative management and control system by using the Openflow technology.
It should be noted that RESTful is a network software architecture principle, in the RESTful architecture, four request manners of POST, DELETE, add, DELETE, modify, and check may be used to perform an operation of adding, deleting, modifying, and checking a specified URL resource, and an application program interface based on RESTful is applicable to a resource-centralized service, a service with a large access amount and a relatively high access effect, and an open application program interface service facing a public network and having a relatively low security requirement, and at the same time, a service call process may be simplified, and access efficiency may be improved, so that it may be applied to an interface between the internet of things management platform 10 and the edge internet of things agent device 20, and an interface between the edge internet of things agent device 20 and the service terminal 30, so as to improve interaction efficiency between the edge internet of things agent device 20 and the internet of things management platform 10 and the service terminal 30. RESTful is also an implementation based on the HTTP protocol, and may transmit data in the form of HTTP, for example, receive service data sent by the service terminal 30 in the form of HTTP, and send the service data to the internet of things management platform 10 in the form of HTTP after performing edge calculation on the service data to obtain service processing data.
SNMP, a simple network management protocol, is a network management protocol of IETF. Due to the strong convenience and universality, the method can be applied to network management between the internet of things management platform 10 and the edge internet of things agent device 20 and between the edge internet of things agent device 20 and the service terminal 30.
Openflow is a network communication protocol, belongs to a data link layer, and can control a forwarding plane of an on-line switch or router, thereby changing a network path taken by a network data packet, and implement SDN based on Openflow, and can implement separation of software and hardware and virtualization of bottom hardware in a network, so that it can be applied to an edge internet of things agent device 20, so as to manage and schedule the whole resources of a cloud-edge collaborative management and control system in cooperation with an internet of things management platform 10.
That is, the cloud-edge cooperation technology is adopted in the application, the cooperation control of the edge internet of things agent device 20 and the internet of things management platform 10 on the service terminal 30 is realized by combining RESTful, SNMP and Openflow technologies, wherein the RESTful is used for realizing interfaces between the internet of things management platform 10 and the edge internet of things agent device 20 and between the edge internet of things agent device 20 and the service terminal 30, and the SNMP is used for realizing the control of the service terminal 30 between the edge internet of things agent device 20 and the service terminal 30 and between the edge internet of things agent device 20 and the internet of things management platform 10, so that the edge internet of things agent device 20 cooperates with the internet of things management platform 10 on the service terminal 30. Meanwhile, inside the edge internet of things agent device 20, the management and scheduling of the whole resources are performed through Openflow.
In this embodiment, the edge internet of things agent device performs data interaction with the internet of things management platform and the service terminal by using the RESTful technology and the SNMP technology to manage the service terminal in cooperation with the internet of things management platform, and manages and schedules the whole resource of the cloud-side collaborative management and control system by using the Openflow technology, so that unified management of the service terminal can be realized, and the service terminal is cooperatively managed and controlled by using the internet of things management platform and the edge internet of things agent device, thereby effectively reducing transmission bandwidth pressure, improving real-time performance of management and control, improving data utilization rate and service level, and simultaneously, the efficiency and convenience of collaborative management and control can be effectively improved by using the RESTful technology, the SNMP technology and the Openflow technology.
