摘要
受到极端低温环境与强电磁干扰的双重影响,智能控制系统的传感器数据采集精度降低、控制信号传输失真,导致融冰刀闸的覆冰状态识别准确性和动作响应可靠性下降。因此,提出多传感器融合下的可移动式智能融冰刀闸设计方法。设置毫米波雷达、红外热像仪等多个覆冰检测传感器,并基于粒子滤波算法融合传感器数据。根据多传感器数据融合结果,设计电阻加热式刀头与高频高压激励作用相结合的刀闸融冰回路,通过约束快速连接接口与高强度刀闸触头,完成可移动式智能融冰刀闸的设计。实验结果表明,传感器对覆冰厚度的识别误差控制在2 mm以内,电阻加热刀头对15 mm冰层的融化速率超过0.1 cm^(3)/s。该设计显著提升了覆冰状态识别的准确性,提高了融冰效率,为电力系统在极端环境下的安全稳定运行提供了有力保障。
Due to the dual effects of extreme low temperature environment and strong electromagnetic interference,the sensor data acquisition accuracy of the intelligent control system is reduced,and the control signal transmission is distorted,ultimately reducing the accuracy of ice cover state recognition and the reliability of action response of the ice melting knife gate.Therefore,a design method for a mobile intelligent ice melting knife gate under multi⁃sensor fusion is proposed.Setting up multiple ice cover detection sensors such as millimeter wave radar and infrared thermal imager,and fusing sensor data based on the particle filtering algorithm.Based on the results of multi⁃sensor data fusion,a knife switch ice melting circuit is designed that combines a resistance heating type blade head with high⁃frequency and high⁃voltage excitation to optimize the fast connection interface and high⁃strength knife switch contacts,completing the design of a movable intelligent defrosting knife switch.The experimental results show that the recognition error of the sensor for ice thickness is controlled within 2 mm,and the melting rate of the resistance heating blade for 15 mm ice layer exceeds 0.1 cm^(3)/s.This design significantly improves the accuracy of ice cover state recognition and enhances the ice melting efficiency,providing a strong guarantee for the safe and stable operation of the power system in extreme environments.
