| 针对“信息孤岛”、采集软件开发难度大和设备维护成本高等问题，本文设计了基于OPC UA协议的工业网关系统。该系统基于.NET Core框架进行搭建，使用ZooKeeper分布式集群对配置文件进行高效管理，设计了公共驱动接口开发设备驱动，通过线程池对不同设备的读写线程进行动态分配，实现同时对不同设备进行数据采集等操作。首先将工业网关、数控（CNC）机床、可编程逻辑控制器(PLC)和机器人等工业设备通过工业以太网进行连接，远程配置界面动态生成工业网关配置文件，并使用ZooKeeper对配置文件进行分布式集群管理。然后工业网关初始化并启动数据采集线程。客户端和工业监控平台均可实现数据显示、设备预测性维护和现场设备异常报警等功能。最后通过实验验证了所设计的工业网关系统的可行性。 |

| In order to solve the problems of ‘information island’, difficulty in acquisition software development and high cost of equipment maintenance, the industrial gateway system based on OPC UA protocol is studied in this paper. The industrial gateway system is built based on. NET Core framework. The configuration files are managed efficiently by using distributed cluster of ZooKeeper. The common driver interface is designed to develop device drivers. The reader and writer threads of different devices are dynamically allocated through the thread pool, which can realize the data acquisition of different devices at the same time. Firstly, industrial control equipment such as industrial gateway, computerized numerical control (CNC) lathe, programmable logic controller (PLC) and robot are connected through industrial ethernet, and the industrial gateway configuration file is dynamically generated in the remote configuration interface. The ZooKeeper is introduced to manage the configuration file generated by remote configuration interface. Subsequently, the data acquisition thread begins to work after initializing industrial gateway. The main functions of client and industrial monitoring platform are the display of history and real-time data, remote controlling and abnormal alarm of the field equipment. Finally, the experiments are presented to verify the feasibility of the industrial gateway system. |
