In regional information collection, in order to avoid network congestion or server downtime due to centralized uploading of file information by a large number of local information collection nodes, time-sharing polling is adopted to allow edge computing platforms to gradually access the sensor information under their jurisdiction collector. As a network site, the edge computing platform provides a data channel interface to the sensor information collectors in the area under its jurisdiction through Web services, and uses the Http protocol for information interaction. During the data receiving process, the edge computing platform will respond to the detected fault signals in a timely manner to the relevant monitoring equipment and maintenance personnel; for the detected routine information, it will perform file compression and temporary storage processing, and wait for the timing to complete before proceeding Data upload.
全局信息采集的实现在于云计算平台作为整个工业网络的信息枢纽中心，通过Web服务提供数据通道接口与边缘计算平台进行信息交互。云计算平台负责将所接收到的压缩文件进行解压分析，通过遍历数据的方式及结合数据挖掘技术来挖掘数据产生的周期、预测工业事件发生概率与时间段、以及实现工业生产全局信息的整理和分析等。The realization of global information collection lies in the fact that the cloud computing platform, as the information hub of the entire industrial network, provides data channel interfaces through Web services to interact with the edge computing platform. The cloud computing platform is responsible for decompressing and analyzing the received compressed files, mining the cycle of data generation by traversing the data and combining data mining technology, predicting the probability and time period of industrial events, and realizing the collation and processing of global information of industrial production. analysis etc.
