摘要
针对输电铁塔基础中钢筋锈蚀检测问题,考虑到传统检测方法存在损坏基础结构、电源续航短等缺点,设计了一种基于电磁检测的无源、无引线埋入式传感器系统。该系统依据LC振荡电路的原理,在铁塔基础的钢筋混凝土结构中预埋入钢丝,然后通过检测其锈蚀断裂的信号来检测铁塔基础中钢筋锈蚀情况。
In view of the problem of steel bar corrosion detection of transmission tower foundation,and considering that the traditional detection methods have shortcomings such as damage to the infrastructure and short power supply life,a passive and leadless embedded sensor system based on electromagnetic detection is designed in this paper.Based on the principle of LC oscillation circuit,steel wire is pre-embedded into the reinforced concrete structure of the tower foundation in this system.Then,corrosionsituation of steel bar in tower foundation is detected by detecting the signal of corrosion and fracture.
