Abstract

Efforts to provide coherent support for interoperability for devices using new technologies remains an ongoing process. Those involved in standards development know this all too well. The challenge remains: How best to keep up with rapidly evolving paradigms such as the IoT, IIoT, Industry 4.0, and similar major shifts? Recent work as part of the IEEE P1451.x standards development looked backwards to identify standards that are mature and extensible, offering a rich functional suite adaptable to new devices and architectures. Standard Commands for Programmable Instruments (SCPI-1999) is one such industry standard, which long ago solved the problem of communicating with devices from many manufacturers. SCPI was an elegant solution for converting unreadable vendor-specific commands to a universal set adaptable by all. Developing interoperability between IoT devices could benefit from a similar SCPI-like approach. To investigate this potential, a typical IoT scenario was developed. Existing nonreadable commands were converted into a SCPI-like command structure. The results of this effort were compelling and suggest that such an approach could achieve interoperability among a wide variety of IoT devices and vendors.
SCPI:物联网与仪表控制的数据交换
为使用新技术的设备的互操作性提供一致支持的努力仍然是一个持续的过程。那些参与标准开发的人对此再清楚不过了。挑战仍然存在:如何最好地跟上快速发展的范式,如物联网、工业物联网、工业4.0和类似的重大转变?最近的工作是IEEE P1451的一部分。X标准开发回顾过去,以确定成熟和可扩展的标准,提供适应新设备和体系结构的丰富功能套件。可编程仪器的标准命令(SCPI-1999)就是这样一个行业标准,它很久以前就解决了与许多制造商的设备通信的问题。SCPI是一种优雅的解决方案,可将不可读的特定于供应商的命令转换为所有人都能适应的通用命令集。开发物联网设备之间的互操作性可以从类似的scpi方法中受益。为了研究这种潜力,开发了一个典型的物联网场景。现有的不可读命令被转换为类似scp的命令结构。这一努力的结果是令人信服的,并表明这种方法可以实现各种物联网设备和供应商之间的互操作性。
