摘　　要：数据交换平台是国家电网公司"SG186工程"重要组成部分。由于数据交换平台所面对的用户广泛、业务复杂,所以在数据交换平台中需要满足自动/手动2种发送方式,在实现自动发送功能的过程中,需要平台提供完善的任务调度模型和实现方法。针对数据交换平台中任务调度的实际情况,在分析比较了现有的任务调度模型、方法的基础上,引入了任务优先级的概念,提出了基于任务优先级的调度模型。该模型充分考虑了数据交换平台调度过程中不同任务的优先级关系,使得数据交换平台可以充分保证优先级较高任务的任务顺利完成,从而提高了数据交换平台的稳定性和可靠性。Data exchange platform is a important part of the State Grid Corporation ＂SG186 project＂, because the users are extensive and the business is complex, the data exchange platform has the need to meet the way of automatic / manual sending, in the process of the implementation of the automatic sending, it is necessary to provide the task scheduling model and the method. According to the demand of task scheduling, on the basis of the research and analysis of the existing scheduling method, the concept of the task priority was introduced, a priority-based task scheduling model was designed, due to the priority of different tasks was considered sufficiently in the platform, the task with higher priority can be finished all right, the stability and reliability of platform were also improved.
