领域级的计算卸载：动机和盈亏平衡点计算
Computation Offloading at Field Level: Motivation and Break-Even Point Calculation
摘要：
智能制造的目标是创建高度灵活和资源优化的工业工厂。此外，提高产品质量是另一个重要目标。这些要求涉及更复杂的控制算法。处理这些算法可能超过资源受限设备（诸如可编程逻辑控制器（PLC））的能力。在这种情况下，计算卸载的必要性。由于工业工厂目前的设计生命周期超过十年，在现实的智能制造场景中，必须考虑这些设备。因此，我们调查复杂的算法对传统PLC的影响，通过模拟它们与负载发生器。此外，我们提出了一个现实的工厂场景，包括有线和无线通信系统的基准。因此，它们的往返时间（RTT）是在网络上有和没有附加负载的情况下测量的。借助这些调查，盈亏平衡点的应用程序的计算卸载的西门子S7系列的两个典型的PLC可以计算。
英文摘要：
Smart manufacturing has the objective of creating highly flexible and resource optimized industrial plants. Furthermore, the improvement of product quality is another important target. These requirements implicate more complex control algo-rithms. Processing these algorithms may exceed the capabilities of resource constrained devices, such as programmable logic controllers (PLCs). In this case, the necessity for computation offloading is given. Due to the fact that industrial plants are currently designed for a life-cycle-time of more than ten years, in a realistic smart manufacturing scenario, these devices have to be considered. Therefore, we investigate the impact of complex algorithms on conventional PLCs by simulating them with a load generator. In addition, we propose a realistic factory scenario including benchmarks for both wireline and wireless communication systems. Thus, their round-trip time (RTT) is measured with and without additional load on the network. With the help of these investigations, break-even points for the application of computation offloading of two typical PLCs of Siemens S7 series can be calculated.
