Abstract: For the situation where the liquid level of a mobile water tank in a port may fluctuate due to vibrations and liquid movement, and considering the existing problems such as insulation failure and insufficient liquid level monitoring accuracy of the water tank, this paper designs an intelligent water tank control system suitable for mobile scenarios. The system adds static wave tubes inside the water tank to suppress liquid movement, and combines multi-sensor fusion technology and compound filtering algorithms of radar, ultrasonic waves, and pressure sensors to effectively solve the problem of liquid level fluctuation interference during movement, achieving precise liquid level monitoring; at the same time, the temperature control system is mainly optimized, adopting a hierarchical heating and dynamic adjustment strategy, and stabilizing the water temperature within the target range under typical port environmental temperatures, with significantly reduced electricity heating energy consumption compared to traditional schemes. This system effectively ensures the stability of the water tank liquid level and the controllability of water temperature under mobile conditions, providing technical support for the precise control of mobile liquid storage equipment.
