摘要
海底沉积物的声学特性对于海底资源勘探、军事、地球物理科学研究等多个领域具有重要意义。针对现有声学沉积物原位探测装置设备工作模式单一、使用局限性大的问题,设计并实现了同时具备实时监测模式、触底自容模式和延时自容模式的声学原位探测装置测控系统。该系统以STM32处理器为核心,实现了电机控制、声信号与传感器信号采集传输、水下视频监控、工作日志存储等功能。测试结果表明,系统在不同工作模式下均可稳定可靠工作,达到设计要求。
The acoustic characteristics of seabed sediments are of great significance in seabed resource exploration,military affairs,geophysical research and other fields.Considering the problems of current in-situ acoustic sediment probe device including single working mode and a great limitation in use,this article designed and achieved an in-situ acoustic measurement and control system,which synchronously has real-time monitoring mode,touch-ground self-contained model and delayed self-contained model.With STM32 processor as the core,this system provided multiple functions,such as electric machine control,acquisition and transmission of acoustic signals and sensor signals,underwater video monitoring and job log storage.Test results demonstrated that this system was characterized by stable and reliable performance and its ability met the design requirements under different working modes.
