Abstract

The invention particularly relates to a PCI (programmable communications interface) aviation serial bus board and a dynamic data loading processing method and aims to solve the problems of complicated hardware design, poor data processing capability, low speed, poor instantaneity and flexibility of conventional PCI communication boards. The PCI aviation serial bus board is used for processing MIL-STD-1553B and ARINC429 bus data in the virtual test system and can dynamically adjust data processing algorithms in virtual test. Processing efficiency of the MIL-STD-1553B and ARINC429 bus data in the virtual test can be effectively improved, and instantaneity of the virtual test system is improved. By the dynamic data loading processing method, programs can be loaded dynamically, so that flexibility and using value of the board are high. The PCI aviation bus board and the dynamic data loading processing method are applicable to virtual test.

Description

technical field [0001] The invention relates to a PCI aviation serial bus board, in particular to a PCI aviation serial bus board and a data processing method for realizing dynamic loading. Background technique [0002] Virtual test refers to a test mode that uses software to replace part or all of the actual equipment in the test system, and integrates the test system to complete the comprehensive ability evaluation. Virtual test technology is based on virtual model, virtual prototype and virtual environment, and uses network-based data transmission to build the entire virtual test system. The testers evaluate the performance of the equipment under test in a combination of virtual and real conditions. Since the whole test is based on the virtual model, it can well solve the long test cycle, large manpower and material resources, uncontrollable natural environmental factors and easy exposure of some parameters of the tested system in the field test, which is not conducive t...
