基于OpenWrt的机床数据监控网关设计

摘要

随着物联网技术的不断发展,传统的工业现场数据采集与互联网相结合已成为发展的必然趋势. 文章提出一种基于OpenWrt的机床数据监控网关设计,该网关可直接与CAN设备、网口设备相连,对采集的数据进行处理存储,网关上部署了Web服务器,方便手机、平板电脑等智能终端对生产现场数据进行监视与控制. 实际应用表明该系统具有成本低、实用性强、易于维护等优点.%With the continuous development of Ethernet, it is an inevitable development trend to combine traditional industrial field data collection with Internet. In this paper, a design of machine data gateway based on OpenWrt was proposed. The designed gateway can be directly connected with the CAN and net-work interface devices, to process and restore collected data. The designed gateway, with Web server e-quipped, makes it convenient to monitor and control the data on the Spot of Production by smart terminals such as cellphones and Tablet PC. Practical application shows that the proposed system has advantages such as costs, practicability, and maintainability.
