Abstract


Modern air defense war ground fire has higher mobility, shorter response time and more accurate fire control computation. The battle of attrition to reduce anti-radiation weapons, air defense systems demand remote control has become increasingly prominent. A military project as a source of this article is based on the current situation of the development of the short-range air defense system. Upgrading of a model anti-aircraft artillery, the project aims to achieve the anti-aircraft artillery remote control, improve mobility and battlefield survivability. The communication system in order to ensure the stability of the upgraded system work, the design of the center of gravity. The project requires the use of the embedded the SOPC system instead of the prototype system based on X86, and through the introduction of embedded real-time systems, to achieve a more stable, efficient and error-free communication. The main research work is a the equipment warehouse communication system design. It will replace the X86-based prototype system communication equipment positions with operating positions. New system based on SOPC platform, and with the highest possible level of integration on-chip Ethernet system, complete SPI-Ethernet data conversion, the device small, modular, and lower power consumption. The concrete realization of the following functions: design SPI master 9 Road SPI time-division multiplexing. 2 design RS codec modules complete SPI port data checksum. 3, the design of the Ethernet controller Ethernet data transceiver. According to the requirements of the subject, based on careful study SOPC hardware system, discussed in detail SPI master module, the concrete realization of RS codec modules, Ethernet controller module; SOPC system analysis software architecture in discussed based on each module preparation of the driver and the software implementation of the system, and the final design completed SOPC-based communication control system design. In the overall framework, this paper analyzes the demand from the project discussed in detail from the hardware platform to build embedded systems based on μC / OS-II real-time operating system, hardware, system testing, driver development, application development, application testing the embedded development process to the final system test provides a reliable platform for further improvement of the system. At the same time, certain guiding significance for development of similar systems. After months of development and debugging, the final system is rigorously tested, are up to or better than the indicators required by the subject, and certainly in the practical application user.
