SBIR Phase I: Triumvi - A Rapidly Deployable, Energy-Harvesting Real-Power Meter

小型企业创新研究(SBIR)第一阶段项目的更广泛的影响/商业潜力是向能源分表领域内的准确性和可负担性转变。这一计量系统将对商业房地产计量市场产生巨大影响。通过大幅降低与精确分段计量相关的成本和知识障碍，并使分段计量的成本与价值保持一致，该技术为电路级能源使用数据的大众市场方法打开了大门。这种商业辅助计量的市场预计将在六年内达到每年25亿美元，但随着低成本、高精度技术的引入，市场可能会大幅扩大。此外，据估计，仅获取计量数据就可以将建筑内的能源消耗降低5%至15%，这意味着广泛部署这些技术可能会带来广泛的环境和能源安全好处。拟议的项目将通过使用能量采集而不是插电式设计来提供收入质量的交流电力分表，从而推动真正功率计量的最先进水平。要做到这一点，需要从根本上改进电路设计、嵌入式软件体系结构和信号分析。其结果是一个自给自足的系统，大大降低了部署和安装成本。该项目将简化系统实施，降低生产成本，并降低Triumvi仪表共享数据的能力，更重要的是，共享采集的能量。具体的关键技术目标包括创建菊花链框架，通过该框架，计量系统中的各个节点可以共享能量和数据，在无数潜在的现场条件下提高准确性，以及创建运行时诊断系统以实时识别和修复人为错误。对这些目标的研究和追求将在实验室和现场进行，在那里安装和精度可以与传统的硬接线测量解决方案进行基准比较。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is a shift towards both accuracy and affordability within the world of energy sub-metering. This metering system will have a dramatic impact on the market for submetering commercial real estate. By drastically reducing the cost and knowledge hurdles associated with accurate submetering and bringing the costs of submetering in line with value, this technology opens the door for a mass-market approach to circuit-level energy use data. The market for this commercial submetering is expected to reach $2.5 billion annually within six years, but could grow substantially larger with the introduction of low-cost, high-accuracy technologies. Additionally, it is estimated that access to metering data alone can reduce energy consumption within a building between 5% and 15%, meaning a wide deployment of these technologies could have wide-reaching environmental and energy security benefits. The proposed project will advance the state-of-the-art in true power metering by providing revenue quality AC power submetering using an energy-harvesting, as opposed to plug-in, design. Doing so requires fundamental improvements in circuit design, embedded software architecture and signal analysis. The result is a self-contained system that drastically reduces deployment and installation costs. This project will simplify the system implementation and reduce the cost of production, and the ability for Triumvi meters to share data and, more importantly, energy harvested. Specific key technical objectives include creating a daisy-chain framework through which individual nodes within a metering system can share energy and data, improving accuracy in the myriad of potential field conditions, and creating a system of runtime-diagnostics to identify, and fix, human error in real time. Study and pursuit of these objectives will take place both in the lab, as well is in the field, where installation and accuracy can be benchmarked against conventional hardwired metering solutions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
