分布式流量积算云服务系统设计与实现

Design and Implementation of a Distributed Cloud Service System Flow Totalizer

针对传统制造行业生产现场数据点分散、仪器仪表智能化程度低、远程通信能力差、操作复杂、造价及维护成本高等问题,结合当前最前沿的分布式云计算技术和物联网技术,通过将现场硬件设备与云端服务程序无缝集成而建立一套网络化的管控集成系统。对现场采集控制设备和云服务中心的组成结构和功能特点进行了详细描述,深入论述了系统各个部分的实现过程,包括分布式实时数据服务器和嵌入式远程终端服务器的开发、流量补偿与积算算法的实现、云端数据归档程序和显控平台的搭建,以及基于TCP Socket连接的XML数据通信的建立等。

In view of the problems of the scattered production field data points of the traditional man-ufacturing industry, the low degree of intelligent instruments and meters, the poor remote communication ability, complex operation, high construction and maintenance costs, etc. , in combination with the current cutting - edge distributed cloud computing technology and Internet of things technology, through the seamless integration of field hardware devices and the cloud service programs, a set of networked management and control integrated system is established. The field acquisition control equipment and the composition structure and function characteristics of the cloud service center are described in detail. The realization process of each part of the system is deeply discussed, including the development of distributed real - time data servers and embedded remote terminal servers, the realization of flow compensation and integrating algorithm, the construction of the cloud data archiving procedures and the display control platform, and the establishment of the XML data communication based on TCP Socket connection, etc.
