工业以太网将取代传统现场总线传输

Category : 技术相关

工业以太网的传输线与一般PC所使用的以太网络线相同。传统的工业传输线路,包括地址线、数据线与控制线等,必须采用一大捆的并行线路,但透过工业 以太网,只需要一条线就可以传送命令来控制数据,不需要使用数量庞大的线材。而工业以太网也拥有工业应用所需要的容余、以及时间定时管理等功能,尽管工业 以太网与家用的PC以太网并非完全相同,然而其精神是一致的。

在工业网络市场不断挑战现场总线的主导地位。流程产业中的工业以太网节点2016年出货量有望达到870万个,比2011年的440万个大增 96%。这意味着2016年工业以太网将占到流程产业中的网络节点的45%,高于2011年的39%。现场总线将为此付出代价,同期内的增长率预计为 51%.

工业物联网将为制造业带来一场变革

Category : 其他

随着智慧行业的发展,制造业效率提升是智慧行业里的一个重要议题。工业互联网可以看成是复杂的物理机械与网络传感器以及软件相集成的一个产物。但是在工业互联网能被制造业普遍采用之前,它将会面临一些严重的挑战。首先,把一家传统工厂转变为一家智慧工厂,需要大量的投资,并采用新的工作方式;还 需要有大数据标准和生态系统来确保不同的工业企业之间能够平滑地运营,在这方面还没有什么进展。当然,各类机械中的大量传感器将会产生海量的数据,会让我 们很快就进入波字节(brontobytes,一千亿亿亿字节)时代。这就要求有能够处理海量数据的强有力的分析工具。此外,所有数据的安全也会成为工厂 能否持续经营的一个生死攸关的问题。当然,物联网将一一解决。

采用工业互联网的好处:1 优化运营效率。2 优化供应链。3 节约成本。
