基于UML的EtherCAT矿井电力监控系统实时性研究

Research on Real-time Performance of Mine Power Monitoring System Based on UML and EtherCAT

摘要:

针对矿井电力监控系统中存在的实时性差、可靠性不足的问题,提出了采用以太网控制自动化技术EtherCAT为通信网络,搭建煤矿井下供电系统,并利用统一建模语言UML建立电力监控系统模型。实验室条件下,依据模型搭建系统实验平台,对EtherCAT矿井电力监控系统实时性进行分析。结果表明,系统网络报文传输时延极小,且故障切除实时性高,能够为后续EtherCAT矿井电力监控系统开发提供技术支持。

Abstract:

In order to solve the problem of poor real-time and lack of reliability in mine power monitoring and control system,EtherCAT,an Ethernet control automation technology, is proposed as a communication network.UML is used to establish a power monitoring and control system model.Under laboratory conditions,based on the model building system experiment platform, the real-time analysis of the power monitoring system of EtherCAT mine was carried out.The results show that the network packet transmission delay is very small and the real-time fault removal is high.This system can provide technical support for the subsequent development of EtherCAT mine power monitoring system.
