摘　　要：随高科技应用领域的不断拓展与提高,传感器测量越来越小型化、高精度及高集成度方向发展。一个传感器内集成多个测量单元,可以进行多个参数的同步测量并输出。本文着重介绍了荷兰Alert Solutions BV公司的GeoBeads多参数传感系统,该传感系统主要包括GeoBeads多参数传感模块以及相关数据采集单元,每只传感模块都可以连续测量多种参数,包括孔隙水压力、温度及倾斜度。通过GeoBeads传感系统在某原体大坝监测中应用,对比分析了多参数传感器与常规传感器监测成果,结果表明该GeoBeads多参数传感系统运行稳定、成果可靠。With the expansion and enhancement of high-tech applications,the measurement sensors are becoming smaller,higher precision and higher integration. A sensor with integrated multiple measurement units and the output function,can measure multiple parameters synchronously. This paper introduces the GeoBeads multi-parameter sensor system made by Dutch Alert Solutions BV company. The sensor system is mainly including GeoBeads multi-parameter sensing module and the data acquisition unit. Each sensor module can measure various parameters continuously including the pore water pressure,temperature and inclined angle. Then,through the application of the GeoBeads sensing system in a prototype dam monitoring,the contrastive analysis between the multi-parameter sensors with conventional sensors about their monitoring results were made. The results show that the GeoBeads multi-parameter sensor system is stable and reliable.
