基于LabWindows/CVI的高效高精度专用测试设备设计

Design of high-efficiency and high-precision special test equipment based on LabWindows/CVI

针对某型号炮射导弹仪器舱的传统测试设备无法满足高效率批量检测的问题,设计了基于LabWindows/CVI虚拟仪器平台的高效高精度专用测试设备。该设备通过标准化的通信协议、模块化、多线程、ACCESS数据库等关键性技术实现了系统自检、设备计量、多工位自动测试和数据管理等功能。经过实验验证,该专用测试设备对同一产品重复性测试时误差不超过0.5%,具有良好的稳定性和准确性。单发产品测试时各项技术指标测试误差较小,并行测试时比传统测试设备缩短了62.857%的测试时间,有效解决了多工位自动化并行测试问题,提高了测试效率和精度,降低了测试成本,促进了国防事业的发展。

Aiming at the problem that the traditional test equipment of a certain type of gun-launched missile instrument cabin can not meet the high efficiency batch test,a special test equipment with high efficiency and high precision based on LabWindows/CVI virtual instrument platform is designed.Through standardized communication protocol,modularization,multi-threading,ACCESS database and other key technologies,the system self-test,equipment measurement,multi-station automatic test and data management are realized.After experimental verification,the error of the special testing equipment for the same product repeatable test is less than 0.5%,which has good stability and accuracy.The test error of each technical index in the single product test is small,and the test time in parallel test is shortened by 62.857%compared with the traditional test equipment,which effectively solves the problem of multi-station automatic parallel test,improves the test efficiency and accuracy,reduces the test cost,and promotes the development of national defense.
