Assessment of Landslides Using Acoustic Real-time Monitoring Systems (ALARMS): Low Cost Sensor Development and Exploitation

全球范围内的边坡失稳每年造成数千人死亡，并破坏建筑环境基础设施，修复费用高达数十亿英镑，导致数千人无家可归，供水和交通等基本服务中断。显然需要低成本的仪器，可以提供斜坡不稳定的早期预警，以便疏散弱势人群，及时维修和维护关键基础设施。目前的仪器系统要么太昂贵，无法大规模使用，要么有技术限制。提出了一种基于声发射实时监测的方法，并通过研究进行了论证。建议开发用于一系列市场的低成本声学斜率位移速率传感器。其中包括供发展中国家使用的具有视觉/听觉警报的低成本传感器，以及发达国家用于关键基础设施状况评估的具有先进诊断能力和无线通信的高成本联网传感器。除了传感器的制造外，还需要在选择、部署和使用适当传感器方面提供技术支持。该项目旨在设计和制造预原型传感器，在现场试验中展示其性能，对英国和国际市场进行市场研究，并制定商业计划，以实现该技术的商业开发。

Slope failures world-wide cause many thousands of deaths each year and damage built environment infrastructure costing billions of pounds to repair, resulting in thousands of people being made homeless and the breakdown of basic services such as water supply and transport. There is a clear need for low cost instrumentation that can provide an early warning of slope instability to enable evacuation of vulnerable people and timely repair and maintenance of critical infrastructure. Current instrumentation systems are either too expensive for wide scale use or have technical limitations. An approach based on acoustic emission real-time monitoring has been developed and demonstrated through research. It is proposed to develop low cost acoustic slope displacement rate sensors for a range of markets. These include very low cost sensors with visual/audible alarms for use in developing countries through to higher cost networked sensors with advanced diagnostic capability and wireless communication for condition appraisal of critical infrastructure in developed countries. In addition to manufacture of sensors, there is also a need for technical support on the selection of appropriate sensors, deployment and use. This project aims to design and build pre-prototype sensors, demonstrate their performance in field trials, conduct market research on the UK and international markets and develop a business plan to enable commercial exploitation of the technology.
