Design Of A CPCI Launch And Control Computer

Launch and control system is an essential component of weapon systems. Withthe development of the new bus technology, measuring technology and missiletechnology, the reliability, real-time response ability, miniaturization and intelligentof the Launch and control system are put forward higher requirements. A CPCILaunch and control Computer, make the Launch and control system moreIntelligence, miniaturization, Improve the reliability and real-time responsecapability of the Launch and control system, meeting the requirements of themodern weapon systems for the launch control computer, with the help of theVxWorks which is a embedded real-time operating system.Based on the full analysis of the launch control computer portfolio needs basedon the analysis, based on the timing positioning, data communications, dataacquisition, analog output, digital input, digital output, and real-time responsecapability requirements, proposed launch control computer combination the overalldesign of programs as well as hardware and software design.For the hardware design, launch and control a computer based combinationCPCI bus functional and design requirements, the paper will be based on the idea ofa modular computer system controls the entire hair is divided into six modules:timing positioning unit module, the communication unit module, data acquisitionunit module, the data conversion unit module, digital input and digital output unitmodule unit module. Each module unified CPCI bus interface.In addition to thetext of the various functional modules and bus interfaces are emphasized, but alsoon the launch control system self-test unit described in detail and design.For software design, respectively, describe the Windows XP system based onLabVIEW various functional board test program development, VxWorks operatingsystem under the Department’s functional board based on PCI device driverdevelopment, FPGA and micro-controller firmware development programdevelopment.Finally, the paper details the steps the system hardware debugging, softwaredebugging and system function self-test procedure steps, the data acquisition unitand analog output unit of the causes of errors are analyzed and proposed to reducethe error approach.
