摘要
由于海底冷泉声探测需要准确的气泡特征信息作为支撑,以真实海底冷泉气泡分布特征为依据,研制了控制精度高、功能全的海底冷泉气体渗漏模拟观测系统。通过模糊PID控制算法对气体流量进行精准控制,相比于常规控制方法流量误差率最高可降低1.5%,可以准确可控地模拟真实环境下的冷泉气泡;通过设计的以太网同步触发器驱动双相机同步拍摄,使拍摄同步误差范围降低1.1 ms,实现了对初始溢出阶段气泡形态的正交同步观测,能够为海底冷泉探测提供数据支持。
As the acoustic detection of seabed cold springs requires accurate information of bubble characteristics, this paper develops a simulated observation system for the gas leakage of seabed cold springs with high control accuracy and full functions based on the bubble distribution characteristics of real seabed cold springs.The gas flow is precisely controlled viathe fuzzy PID control algorithm. Compared with the conventional control method, the flow error rate can be reduced by up to 1.5% and the cold spring bubbles in the real environment can be simulated accurately and controllably. The dual cameras are driven viaan Ethernet synchronous trigger, and thesynchronized shooting reduces the shooting synchronization error range by 1.1 ms.The system accurately realizes the orthogonal synchronous observation of the bubble shape in the initial overflow stage and provides data support for the detection of seabed cold springs.
