Cannon Signal Simulation System Based On Redundant Can Bus

In order to meet the future needs of the digitized battlefield, artillery technology is developing in a direction of independent, informationized and intellectualized. In this thesis, the digitized artillery signal simulating system is studied and developed with high-performance of 32-bit embedded dual redundant CAN interface card as its main hardware platform, and LabVIEW as its software platform. The system is controlled by the computer software to complete the work state of artillery analog signal generation, signal transmission and reception, data analysis processing and other functions to meet the artillery digital information system's development and debugging needs.Firstly, the features and functions of the CAN Bus, Virtual Instrumentation technology and LabVIEW are briefly introduced in this thesis. With reasonable selecting ARM Core processor LPC2132 and Independent CAN Controller SJA1000, the design of CAN Bus module hardware PCI-CAN communication interface card is completed. Then the driver of PCI-CAN communication interface card is developed in LabVIEW, a virtual instrument development platform. In the hardware platform, according to the characteristics and the requirements of system's communication, the data formats of communication is formulated based on the standard CAN protocol, the hardware-based dual redundant scheduling algorithm is designed, and the system software in LabVIEW software platform is developed. And in accordance with the order of signal generation, signal transmission and reception, the signal analysis, the functions of each module are introduced.The whole system consists of two PC machines, the CAN communication adapter interface card included. Using the principal-subordinate structure, the bidirectional communication is achieved through the CAN communication adapter interface card. CAN Bus data can be transmitted by CAN interface card, with which communications between PC machine and the following CAN control network can be completed. So PC can receive each kind of data and operating parameters of the artillery signals in time. Thesis in ARM7-based microcontroller dual redundant communication adapter PCI-CAN interface card for dual CAN redundant communications, a dual redundant CAN communication software development is completed, and the key ideas and technology of software design are elaborated in details. The development of this system has truly realized the infrastructure of digital artillery, and offers a good reference to digitization transformation of other traditional weapons and equipments.
