我们提出了一个3.5年的嵌入式传感部署的设计和评估在密特拉神庙的马戏团Maximus，联合国教科文组织保护的地下考古遗址在罗马（意大利）。我们工作的独特之处在于通过热能和动能收集能量。然而，能源的极度稀缺和不稳定的可用性给系统软件、嵌入式硬件和能源管理带来了巨大挑战。我们通过多年部署首次测试间歇计算、低功耗硬件和能量收集方面的现有解决方案来解决这些问题。通过三个主要的设计迭代，我们发现这些解决方案作为孤立的孤岛运行，缺乏集成到一个完整的系统中，表现不佳。相比之下，我们展示了硬件/软件协同设计的高效性能，其特点是精确的能量管理和捕获能量源和感测量之间的耦合。同时安装一个电池供电的系统也使我们能够在要求苛刻的环境中进行能量收集的比较研究。尽管后者降低了能源可用性，从而将数据产量降低到电池提供的数据产量的约22%，但我们的系统提供了对现场环境条件和结构健康的可比水平的洞察。此外，与现有的能量收集部署不同，在最好的情况下，这些部署仅限于几个月的操作，我们的系统在近2年的时间里零维护，包括由于COVID 19封锁而导致的3个月的网站无法访问。
We present the design and evaluation of a 3.5-year embedded sensing deployment at the Mithræum of Circus Maximus, a UNESCO-protected underground archaeological site in Rome (Italy). Unique to our work is the use of energy harvesting through thermal and kinetic energy sources. The extreme scarcity and erratic availability of energy, however, pose great challenges in system software, embedded hardware, and energy management. We tackle them by testing, for the first time in a multi-year deployment, existing solutions in intermittent computing, low-power hardware, and energy harvesting. Through three major design iterations, we find that these solutions operate as isolated silos and lack integration into a complete system, performing suboptimally. In contrast, we demonstrate the efficient performance of a hardware/software co-design featuring accurate energy management and capturing the coupling between energy sources and sensed quantities. Installing a battery-operated system alongside also allows us to perform a comparative study of energy harvesting in a demanding setting. Albeit the latter reduces energy availability and thus lowers the data yield to about 22% of that provided by batteries, our system provides a comparable level of insight into environmental conditions and structural health of the site. Further, unlike existing energy-harvesting deployments that are limited to a few months of operation in the best cases, our system runs with zero maintenance since almost 2 years, including 3 months of site inaccessibility due to a COVID19 lockdown.
