关于黄河的冰期,很难获得冰数据信息。要有效掌握黄河典型河段冰期的冰演化过程,本文提出了一种定点空中耦合雷达远程监控装置。该装置主要由空气耦合雷达冰厚测量传感器,雷达水位测量传感器,温度测量传感器,高清红外夜视仪,远程开关控制,遥测通信机,太阳能和风能供应,防雷,和回转臂钢塔。集成监测装置可以监测冰的厚度,水位,空气温度,冰面温度,和其他相关参数实时。目前,装置获得了2020年至2021年冰期固定点的换冰过程。通过与手动数据的比较,水位和冰层厚度监测结果的平均误差约为1厘米。该装置在固定位置实现了整个周期内冰层厚度和水位变化的实时监测。通过视频监控,它可以定期拍摄图片和视频,实现可视化河流和监控数据的连接。研究成果为黄河冰期水文监测提供了新模式和新技术,具有广阔的应用前景。
Regarding the ice periods of the Yellow River, it is difficult to obtain ice data information. To effectively grasp the ice evolution process in the ice periods of the typical reach of the Yellow River, a fixed-point air-coupled radar remote monitoring device is proposed in this paper. The device is mainly composed of an air-coupled radar ice thickness measurement sensor, radar water level measurement sensor, temperature measurement sensor, high-definition infrared night vision instrument, remote switch control, telemetry communication machine, solar and wind power supply, lightning protection, and slewing arm steel tower. The integrated monitoring device can monitor ice thickness, water level, air temperature, ice surface temperature, and other related parameters in real time. At present, devices have obtained the ice change process of fixed points in ice periods from 2020 to 2021. Through a comparison with manual data, the mean error of the monitoring results of the water level and ice thickness was approximately 1 cm. The device realizes the real-time monitoring of ice thickness and water level change in the whole cycle at the fixed position. Through video monitoring, it can take pictures and videos regularly and realize the connection between the visual river and monitoring data. The research results provide a new model and new technology for hydrological monitoring in the ice periods of the Yellow River, which has broad application prospects.
