SBIR Phase I: Acoustic Beamforming for Process Monitoring

*96-60548 Cutler这个小型企业创新研究(SBIR)第一阶段项目将调查现场工艺设备产生的声音的收集和分析，以诊断工艺状态。这项新技术将结合用于隔离和监测特定发声地点的声束形成和用于确定设备运行参数的声音特征分析。设备产生的声音和振动是设备状态的可靠标志。这项技术将允许集中监控通常不会访问的系统元素(如管道)，并在不需要大量硬件安装的情况下对整个过程状态进行高水平的监督监控。包括阀门和管道将允许自动检测和定位系统故障，如泄漏、湍流和蒸汽锤击，这些故障是传统过程监控设备无法处理的。第一阶段将开发一种低成本、易于定制的仪器，该仪器将同样适用于新制造厂的安装和现有工厂的非侵入性改造。预计在大型预测性维护市场将有商业应用。安装成本低，操作简单，人员需求少，在过程监控和预测性维护领域将是有用的。***

*** 96-60548 Cutler This Small Business Innovative Research (SBIR) Phase I project will investigate the collection and analysis of sound generated by in-situ process equipment as a diagnostic of process state. The new technique will combine acoustic beam forming for isolation and monitoring of specific sound generation sites and analysis of sound signatures for determination of equipment operational parameters. Sound and vibration generated by equipment is a reliable indication of equipment state. This technique will allow focused monitoring of system elements not typically accessed (such as piping) and high level, supervisory monitoring of overall process state without extensive hardware installation. Inclusion of valves and piping will permit automated detection and localization of system malfunctions such as leaks, turbulence, and steam hammering that are not treatable with traditional process monitoring equipment. Phase I will develop a low cost, easily customizable instrument that will be equally applicable to installation in new manufacturing plants and to non-intrusive retrofit of existing plants. Commercial applications are expected in large predictive maintenance market. Low cost installation, simple operation, and small personnel requirements will be useful in the process monitoring and predictive maintenance fields. ***
