Design On The Basis Of PCI Bus Helicopter Deck Net Simulate System

In recent years, with the development of computer network. Some military great power develop plenty of research in digital warship. It' s warship net system has been formed some scales, and formed a net run precept which is fit for itself warship system characteristic. But in our country, digital warship is begin. What' s more, it is limited to the subsystem local area network build, such as warship driver system, warship weapon system, warship helicopter deck net aid system and so on. This text has been exploring mainly warship helicopter deck net aid system.First of all, this text expound substrate design of warship net system, included the design of subsystems, data collection, data transmission, computer interface control and computer control software and so on. Introduced their function and work principle.Data transmission is one of the most important control parts of warship system. The control effect and efficiency was influenced directly by rate of data transmission, reliability of data transmission and security of data transmission. So there is important significance in researching it. In there, we-developed a CAN bus and RS485 bus communication control card based on PCI bus.At last, we make this card to realized the communication of the subsystems, and make some synthesize disposals by make use of VC++ and OpenGL. This card can realize reliably the data transmission of warship system.
