中文摘要:
      为了解决工厂设备品牌多样化、通讯协议各不相同、采集难度大等问题,研究了基于.NET Core架构的远程数据采集和监控系统。该系统借鉴了异构的数据存储方式、分布式网络模型和数据分析模型,使用.NET Core框架开发完成。首先将嵌入式工控机和PLC设备通过工业以太网连到同一局域网并进行通信,对可编程逻辑控制器(PLC)设备的运行状态进行实时数据采集,并上传到云端服务器,Web端可以远程查看PLC设备的实时数据,以及对PLC设备的工作参数进行数据分析,当分析结果显示设备出现故障时,云端服务器通过短信通知现场工程师PLC设备出现故障,当现场工程师无法调试设备时,远程工程师还可以通过Open VPN对设备进行远程调试。最后通过实验验证了系统的可行性。
英文摘要:
      In order to solve the problems of factory equipment brand diversification, different communication protocols and collection difficulty, the remote data acquisition and monitoring system based on the .NET Core architecture is studied. The system is developed by using heterogeneous data storage methods, distributed network models and data analysis models. Firstly, the embedded industrial computer and programmable logic controller (PLC) equipment are connected to the same local area network through industrial Ethernet. The operating status of the PLC device is collected in the real-time way,and then is uploaded to the cloud server. Real-time data of PLC devices can be obtained and analyzed remotely from the web side. When the analysis result shows that the device is broken down, the cloud server notifies the field engineer by message. If the field engineer cannot debug the device, the remote engineer can also remotely debug the device through Open VPN. Finally, the feasibility of the system is verified by experiments.
