摘要 监控系统在现场一次设备发生故障时应推出相关画面 ,而运行人员也时常需要显示指定的画面 ,这势必造成对显示资源的竞争。介绍了一种解决方案 :根据现场运行工况 ,给各种画面按优先级分类。利用队列和底牌这种数据结构 ,在图形竞争显示资源时 ,对图形进行相应的排队操作 ,即插入操作、删除操作、设置正常画面操作和取队画面操作。采用排队选择机制 ,选出某一时刻最为紧迫的一幅画面加以显示 ,而其余的画面则进入相关队列或底牌。 The relevant picture should be displayed on monitoring system when the fault of primary devices occurs, but the operator may be calling another picture display at the same time, in order to solve this problem, a picture display dispatch strategy for monitoring system used in power system is introduced. Every picture is assigned a priority based on the real operation conditions. When picture display conflict happens,the queuing operations are proceeded by applying a special data structure, queue and base. The operations are insertion, deletion, normal picture setting and front picture fetch. The most urgent picture is selected and displayed on CRT, the others are arranged into queue or base.
