摘　　要：内悬浮抱杆杆身压力是抱杆设计和使用中需要重点关注的关键控制指标之一。针对内悬浮抱杆组塔施工过程中易发生倾角过大、拉线或承托绳受力超限等安全问题,研制了包含杆身压力监测在内的抱杆工作状态实时智能监测与预警系统。该系统以杆身轴向压力-倾角一体化传感器监测抱杆杆身的轴向压力和倾角,以拉力传感器监测起重、拉线和承托绳拉力,以风速仪监测环境风速。通过无线发射模块将监测数据反馈至监测系统,通过内嵌算法实时判断抱杆状态的安全性,当超出预设阈值时发出声光警示。将实际吊装试验与理论计算值进行对比,完成工程应用。The pressure of the inner suspension pole body is one of the key control indicators that need to be focused on in the design and use of the pole.A real-time intelligent monitoring and early warning system for the working status of the internal suspension pole tower is developed to address safety issues such as excessive inclination,excessive force on the stay wire or support rope during the construction process,including pole body pressure monitoring.The system monitors the axial pressure and inclination angle of the pole body using an integrated sensor for the axial pressure and inclination angle of the pole body.The tension sensor monitors the tension of the lifting,pulling,and supporting ropes,and the anemometer monitors the environmental wind speed.The monitoring data is fed back to the monitoring system through a wireless transmission module,and the safety of the pole state is determined in real-time through an embedded algorithm.When the preset threshold is exceeded,an audible and visual warning is issued.A comparison was made between the actual lifting test and theoretical calculation values,and engineering applications were completed.
