9860247 This Small Business Innovation Research Phase I project is addressed to the development and testing of a wireless system which will make use of Acoustic Emission Technology that is both practical and affordable on longer sections of pipeline pipe. The resulting system will enable the user to locate, within plus or minus 5 feet, the origin of sounds of distress from the pipe, enabling far less expensive point repairs rather than outright replacement. Development is based on signal processing techniques to identify the very distinguishable sounds of distress and an exclusive method of determining the location of the sounds through use of multiple wireless sensors. If the research is successful, the results have the potential of saving water districts from $1million to $15 million per mile in replacement costs for the nation's 20,000+ mile ($40 billion) concrete water main infrastructure. It will have application at water districts and electric utilities worldwide. The company projects their acoustic pipe testing revenues to reach $36,000,000 within 5 years, assuming a 5% market penetration. Longer term application to other pipe and civil structures is also foreseen.

9860247这个小型企业创新研究第一阶段项目的目的是开发和测试一种无线系统，该系统将利用声发射技术，在较长的管道段上既实用又经济。由此产生的系统将使用户能够在正负5英尺的范围内定位管道中遇险声音的来源，从而实现更便宜的点维修，而不是直接更换。开发是基于信号处理技术，以识别非常可区分的遇险声音，并通过使用多个无线传感器确定声音位置的独家方法。如果研究成功，其结果有可能为全国2万多英里（400亿美元）的混凝土主水基础设施每英里节省100万至1500万美元的更换成本。它将在世界各地的水区和电力公司得到应用。该公司预计，假设市场渗透率为5%，他们的声学管道测试收入将在5年内达到3600万美元。长期应用于其他管道和土建结构也可预见。
