基于SCPI的运载火箭遥测系统自动测试平台设计

Design of Automatic Test Platform in Carrier Rocket Telemetering System Based on SCPI

摘要:

针对目前火箭遥测系统专属测试设备操作复杂、通用性差等特点,提出一种基于SCPI指令的虚拟仪器智能测试方案,利用SCPI指令完成程序对智能设备的输出控制,结合TCP/IP通信技术、数据库访问技术以及在LabVIEW程序中完成Excel动态存储技术等,实现了火箭遥测系统电性能自动测试、闭环测试、在线监测等功能,测试结果表明,测试平台极大地提高了系统测试效率,测试数据可靠性好,可满足运载火箭遥测系统电性能测试工作,具有较好的推广价值。

Abstract:

In view of the equipments which Telemetering System used were excluded and complicated,an Automatic Test Platform based on SCPI was designed for the electrical performance test in Telemetering System,which make the best use of the intelligent instruments’ analysis capabilities on SCPI commander to realize the control of the outputs,combining with the TCP/IP、Database and Excel storage technology in LabVIEW,the Telemetering System test platform has realized automatic testing、closed loop testing and on-line monitoring. The application shows that this test method can greatly improve the efficiency of the system test, the test results are reliable to meet the system’s requirements. It is worthy using widely.
