针对传统监控与数据采集(SCADA)系统处理海量信息的局限性,提出一种异步调用的SCADA处理模式,将SCADA数据处理服务的提交和处理请求设计为一个异步过程,未处理的数据以先进先出的方式存储在缓存中等待处理,确保处理海量信息时不丢失事项。系统基于公共信息模型(CIM)建模并在Net平台上实现。大容量数据的雪崩测试及现场试运行表明异步调用模式的SCADA系统处理的可用性和优势。 In view of the limitation of traditional supervisory control and data acquisition (SCADA) system to deal with massive information, a asynchronous SCADA processing mode is proposed, the submission and processing request of SCADA data processing service is designed as an asynchronous process, the unprocessed data is advanced Out of the way stored in the cache waiting to be processed, to ensure that the handling of massive information without losing items. The system is modeled on the Common Information Model (CIM) and implemented on the Net platform. Avalanche testing and on-site commissioning of high-volume data indicate the availability and benefits of asynchronous call-mode SCADA system processing.
