摘　　要：桥梁整体安全性能的一个重要评价指标是斜拉索当前的索力值。研制了基于6LoWPAN的分布式无线索力监测系统,首先介绍系统的总体结构,分别给出了系统的软、硬件设计以及数据传输策略,然后进行了振动测试与实际拉索测试实验。实验表明,监测系统能够准确地进行分布式远程索力监测,为桥梁远程、长期监测提供了一种便捷高效的测试系统及方法,应用前景广阔。Cable force of bridge cable is an important index to measure the safety of bridge. A wireless cable force measure system based 6LoWPAN and MEMS was proposed. First, this paper introduced the overall structure of the system and the principle of cable force measurement by the method of vibration spectrum, and then it designed the cable force measure system. Finally the precision vibration test bench and real engineering cable test was developed. Experiments show that the distributed wireless sensor system based on MEMS and 6LoWPAN can accurately carry out remote cable force detection. It provides an effective method for bridge safety monitoring.
