Research On The Application Of VxWorks Embedded Operation System On Multi-beam Fish Finder

The system software of multi-beam fishfinder, which is a complicated equipment, not only includes necessary signal acquisition processing programs, but also includes aboundant complicated display and control programs. Besides, high-performance multi-beam fish founder integrates advanced functions, such as with electronic seamap, GPS navigation and etc. These functions make the system software more complicated which reduce the reliability. So, it is the key technology of improving software's reliability and reducing the difficulty of development that introduce the high performance real-time embed-in operating system to the develoement of multi-beam fishfinder disaplay platform.Based on the Heilongjiang SMEs Innovation Fund projects—multi-fishfinder supersonic fishdinfer, VxWorks operating embed-in system is applied to the development of multi-beam fishfinder display platform. The operating system is transplanted. The periphery device driver program is developed. The display and control interface is designed and accomplished. The detailed content includes three aspects as follows:After analyzing the working environment of the fish founder and the performance requirements of the display and control system, hardware and software programme which based on the combination of ACS-4051VE PC/104 board and VxWorks embedded systems is proposed. The selection of related parameters are demonstrated.1. The transplant from VxWorks embedded operating system to PC/104 board is completed, which supplies a software platform. At the same time, the the development of board-level support package BSP and external device driver is accomplished.2. The display and control interface of the multi-beam fishfinder is achieved using WindML and Zinc components.3. The innovation of the dissertation is that the introduction of the concept of embedded when design the display and control platform of the fishfinder, using the programme proposed in the dissertation. The display and control system of the fishfinder can provide users with significant friendly interface, guarantee the real-time and system reliability effectively and provide conditions for the future expansion of the function of the system.
