摘　　要：针对传统的水下主动声呐探测系统设备通用性较差,以德州仪器公司的OMAP-L138低功耗浮点双核处理器为核心,设计一种水下主动声呐探测指令控制系统。在CCS开发环境中,以可剪裁可智能调度多个线程的实时操作系统内核SYS/BIOS为基础架构,对数字信号处理器采用C语言编写指令控制程序,按照功能进行模块化设计,以统一的格式在各执行设备间进行指令及数据通信。系统功能调试验证结果表明,该系统提高了水下主动声呐探测系统的实时通信效率,能有效节省处理器的开销,并能够大规模数据传输与实时处理。采用模块化设计系统软件,易于维护,具有可扩展性、可再用性和可移植性。In view of the poor generality of traditional underwater active sonar detection system,a command control system for underwater active sonar detection is designed based on OMAP-L138 low-power floating-point dual-core processor of Texas Instruments.In the CCS development environment,the real-time operating system kernel SYS/BIOS,a scalable real-time kernel which provides preemptive multithreading,is used as the infrastructure,and the command control program is written in C language for the digital signal processor.The modular design is carried out according to the function,and the command and data communication is carried out among the execution devices in a unified format.The debugging results show that the system improves the real-time communication efficiency of the underwater active sonar detection system,effectively saves the cost of the processor,and is capable of large-scale data transmission and real-time processing.The modularization design of the system software makes it easy to maintain,and it improves its scalability,reusability and portability.
