Design And Realization Of The Theory Test Platform Software Of The UVA Data-Acquisition Subsystem

The flying data collected by the UVA is an important mean to obtain messages. The progress to obtain parameter data need a complete data-acquisition system to achieve. The UVA flying data-acquisition system software this thesis works on is such a system used for testing principle on the ground.In order to verify the functionality and feasibility of the experimental features in the real aircraft systems, set up simulation system on the ground as test platform. The simulation test platform has hardware system, which with the same connection as the original. With this test hardware system,set up running software and process further test and verification to the ground test platform basing on the request of the testing sub-system.Aiming to accomplish the parameters acquiring, the data frame transmission, the commanding words interactive and the data frame process of the systems acquisition, this thesis meet the request of the multi-channel data frame receiving, high speed data transmission and mess data storage. The theory test platform software is based on MFC structure with CVI module control to accomplish the main function. In order to meet the request of the speed and accuracy of the multi-channel data acquisition of the theory test platform, the major software is set up with two sub-module to accomplish hierarchical control. These two modules exchange data with data bus and command bus. In the end, complete the collection, data classify and storage.On the basis of setting up theory test platform, verify and test the collection theory and processing of the system thoroughly. Testing the condition of the transmission of the bus data through loading enough experimental data. Judging whether the transmission of the parameter and scheme meets the request of the project through the data report which the master record unit create.This sub-system theory testing platform has already ran several event of system parameter testing experiments and pressure tests, it has good function stability. The theory test platform meets the request of the UAV science test system,the scheme has good feasibility, it has the ability to complete data collection, processing and system control. The theory test platform achieves outstanding data receive speed and data processing ability with multi-mode testing verification.Compared with traditional data-acquisition system, the system in this thesis has more data acquisition channels and better efficiency. It also has outstanding practicability and more convenient operations, integrates several functions during data-acquisition.
