Problems solved by technology

However, since the hardware structure and software system of the traditional underwater active detection system are relatively fixed and closed, it is an independent device with a single machine and single control. Each underwater active detection system corresponds to different equipment and different purposes. Insufficient versatility and expansion capabilities limit the expansion and compatibility of the underwater active detection system and bring difficulties to system maintenance and upgrades

Embodiment Construction

[0042] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0043] In this embodiment, the DSP chip is used as the operating platform to realize the system control function in the underwater active detection system. The software program design adopts SYSBIOS, and uses a unified communication format to perform command and data communication between execution devices.

[0044] The software program design of the real-time information processing and data transmission method of the underwater active detection system adopts SYSBIOS. According to the functional requirements of the underwater active detection system, three task threads are created: TSK_Process, TSK_TCP and TSK_UDP. Among them, TSK_TCP is a TCP communication task, responsible for command reception and response communication with the host computer, with the highest priority; TSK_UDP is a UDP communication task, responsible for transmitting the underwater acoustic si...

Abstract

The invention relates to a real-time information processing and data transmission method for underwater active detection systems. By implementing instruction and data communication between execution equipment through a uniform format, real-time communication efficiency of the underwater active detection systems can be improved, and overhead of a central processing unit (CPU) is reduced. According to the method, based on a scalable real-time operating system kernel SYSBIOS, task processes queue and wait for execution under dispatching of an application program according to the task and interruption priority, so that the waiting time for executing tasks is effectively reduced, and data throughput of the system is improved. By the method, flexible communication with the execution equipment can be realized; and the method can be conveniently transplanted to the underwater active detection systems with different application functions such as sonar, torpedo homing and mines.

Description

technical field [0001] The invention relates to a real-time information processing and data transmission method of an underwater active detection system. Background technique [0002] The underwater active detection system has broad application prospects in underwater target detection and recognition, marine environment detection and so on. The current widely used underwater detection system uses a large number of embedded processors as the control components of the system, and the signal processing capability has been significantly improved. However, since the hardware structure and software system of the traditional underwater active detection system are relatively fixed and closed, it is an independent device with a single machine and single control. Each underwater active detection system corresponds to different equipment and different purposes. Insufficient versatility and expansion ability limit the expansion and compatibility of the underwater active detection syste...
