Embodiment Construction

[0039] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 1 Shown is a schematic diagram of the internal modules and data flow of a single node of the distributed real-time library of the present invention. It can be seen from the figure that the entire distributed real-time library is composed of multiple stand-alone real-time library nodes. Each node can run independently or together form a distributed real-time library. Multiple real-time library nodes use link layer multicast technology and UDP multicast technology to realize communication between nodes, use the publish / subscribe model to provide access interfaces through the message center, and accelerate access to network data through intelligent caching technology, thus forming a physically distributed mode operation, a logically single distributed real-time library system. Each real-time library node includes memory re...

Abstract

The invention discloses a real-time database data transmission method applied to distributive energy management. The method is implemented based on the distributive real-time database, and the whole distributive real-time database is composed of a plurality of stand-alone real-time database nodes; each node can be independently operated or all nodes can form a distributive real-time database; the plurality of real-time database nodes communicate with each other, and a distributing / subscribing model is operated at a message center to provide an access interface, so as to form a distributive real-time database system which is physically distributively operated and logically stand-alone. According to the method, each real-time database node is at the same level and no key node is provided, so that the reliability of the whole real-time database is improved; the whole real-time database cannot be influenced by the fault of some node; therefore, the problem of inconvenient communication caused by a plurality of intelligent devices, large data acquiring quantity, uneasy allocation of real-time database of single monitoring system of the large-scale distributive energy managing system can be solved.

Description

technical field [0001] The invention belongs to the field of distributed energy management, and in particular relates to a real-time library data transmission method for distributed energy management. Background technique [0002] With the vigorous development of distributed energy, the management of distributed energy has become increasingly important. The use of various smart devices in the distributed energy management system is also increasing, and a large number of smart devices are connected to the system, which brings great pressure to the real-time library. In order to improve the processing performance of the real-time library, one method is to improve the processing capability of the single-machine real-time library by improving the hardware performance, and the other method is to disperse the pressure of the single-machine real-time library through multiple nodes. The former has better performance when the data volume is fixed, but it will cause inconvenience whe...
