Distributed-cache-based acquisition task scheduling method in purchase, supply and selling integrated electric energy acquiring and monitoring system

Abstract

The invention relates to a distributed-cache-based acquisition task scheduling method in a purchase, supply and selling integrated electric energy acquiring and monitoring system. The distributed-cache-based acquisition task scheduling method comprises the following steps of: creating acquisition tasks by a task manager according to a task template, storing the acquisition tasks in a task data area of a distributed cache, distributing tasks by the task manager in a balanced manner according to load situations of all acquisition nodes in a preposed acquisition cluster, enabling the acquisition nodes to get the tasks through a message bus, starting corresponding task executing flows and updating executing states of the tasks back to the distributed cache after completing the execution of the tasks. The distributed-cache-based acquisition task scheduling method disclosed by the invention has the benefits of well solving a task scheduling problem of bulk data, fundamentally solving the bottleneck problems of a great deal of types of data and large data quantity of the purchase, supply and selling integrated electric energy acquiring and monitoring system and realizing high-efficient, balanced and stable scheduling of the acquisition tasks.

Description

technical field [0001] The invention relates to a method for scheduling collection tasks based on distributed cache in an integrated electric energy collection and monitoring system for purchase, supply and sale. The method is also applicable to traditional electric energy collection and monitoring systems. Background technique [0002] Traditional electric energy collection and monitoring systems are independent and decentralized systems. Generally, there is one system for power collection at substations and power plant gateways, and another system for power user information collection. Because the data is scattered, as long as the general system based on The task scheduling controlled by the acquisition program between the acquisition nodes can satisfy the function of task scheduling. [0003] The new type of integrated electric energy collection and monitoring system for purchase, supply and sale needs to integrate power plant substations and power users into one platfor...

AI Technical Summary

Problems solved by technology

[0006] When the state of some nodes in the collection cluster changes, the collection service will be interrupted for a period of time. The above task scheduling method will cause some tasks to be lost due to the frequent start and stop of the collection nodes in the collection cluster; there is no effective monitoring of task execution. , it is not easy to recycle failed tasks, and it is difficult to achieve load balancing, etc.
