介绍了一种新型低成本、低功耗电阻率层析成像系统（PRIME --主动式基础设施监测与评估）的研制。PRIME旨在提供有关土方工程内部状况的连续近实时信息，帮助预测故障并进行及时干预。传统的资产监测涉及检查表面（由地面上的人或从空中拍摄的照片）和使用点传感器，如水分含量和倾斜仪，这些传感器只提供传感器附近的信息。但是PRIME使用成像技术来跟踪水分含量变化和地面运动，从而在更早的阶段发现问题。还提供了一个部署的PRIME监测泄漏的运河堤防的例子。
The development of a new low-cost, low-power, electrical resistivity tomography system (PRIME - Proactive Infrastructure Monitoring and Evaluation) is described. PRIME is designed to provide continuous near-real-time information on the internal condition of the earthworks, helping to predict failures and enable timely intervention. Conventional asset monitoring involves examining the surface (either by people on the ground or from aerial photos) and using point sensors, such as moisture content and tilt meters, which only give information in the immediate vicinity of the sensor. But PRIME uses imaging for the volumetric tracking of moisture content changes and the detection of ground movement, thereby identifying problems at a much earlier stage. An example of the deployment of PRIME to monitor a leaking canal embankment is also provided.
