特制曝气头喷出形成气液泡防冰机理是基于水中气液泡上升行为：形状尺寸及速度、气液泡上升阻力和过冷水的形成、携带水量等因素。
我司通过系统详尽地研究气（液）泡法防冰的机理，并结合实际工程的工况及要求，首次提出微气液泡防冰除冰装备的控制思想。
整体装备由三部分组成：1）供气系统及管道；2）曝气组件；3）控制系统。
控制系统是大脑，曝气组件为功能体，供气系统及管道为资源供体。
控制系统由三个行为系统组成：1）自动化控制系统（PLC）；2）远程数据采集与监控系统（SCADA）；3）人工机械集控汇流排（阀组，Confluence bus）。
控制系统通过各种工况信号检测/传感器（温度、水压力/水深、气源压力/流量及电磁阀等，及各功能设备和器件的工作状态等），实现智能形成气液泡。进行人机协调，满足防冰效果及要求。
The anti-icing mechanism of gas-liquid bubbles generated by specially customized aerators relies on the rising behavior of bubbles in water, including factors such as bubble shape, size, ascending velocity, rising resistance, supercooled water generation and water carrying capacity.
Our company has conducted systematic and in-depth research on the anti-icing mechanism of the gas-liquid bubble method. Combined with actual working conditions and engineering requirements, we pioneered the control concept for micro gas-liquid bubble anti-icing and deicing equipment.
The complete equipment consists of three core parts: 1) Gas supply system and pipelines; 2) Aeration assemblies; 3) Control system.
The control system acts as the brain, the aeration assemblies serve as functional executors, and the gas supply system with pipelines functions as the resource provider.
The control system comprises three subsystems: 1) PLC automatic control system; 2) Remote data acquisition and SCADA monitoring system; 3) Manual mechanical centralized control manifold (valve groups).
By collecting signals from multiple operating condition sensors (temperature, water pressure/water depth, gas source pressure/flow rate, solenoid valves, plus operating status of all functional equipment and components), the control system intelligently regulates gas-liquid bubble generation. It realizes man-machine coordinated operation to meet targeted anti-icing performance standards.
