工业4.0与智能制造时代面临的第一个问题将是互联与互通问题,互联解决物理性连接的基础条件,而互通则解决数据间的交互,而对于新的时代,互操作性—即在不同网络里的数据透明访问能力,互联是基础,互通是手段,而互操作是目的。1通信需求是智能时代第一步在4.0时代,我们将这些通信的需求分为:M2M:机器到机器的通信,包括实时数据的交互,如机器人与包装线的互联,灌装设备与旋盖等,往往要求较高的实时 Industry 4.0 and the era of intelligent manufacturing will face the first problem interconnection and interoperability issues, the Internet to solve the basic conditions of physical connection, and interoperability is to solve the interaction between data, and for a new era, interoperability - that is different Transparent access to data in the network, the Internet is the basis for interoperability is the means, and interoperability is the goal. 1 Communication requirements are the first steps in the smart era In the 4.0 era, we divided the needs of these communications into: M2M: Machine-to-machine communication including real-time data interaction such as robotics and packaging lines interconnection, filling equipment and capping Etc., often require higher real-time
