Remote Sensing Ground Station Automatic Test System Design and Application

摘要:

遥感卫星地面站的G/T值(品质因数)和系统误码特性是遥感卫星地面站最重要的系统指标,是测试遥感卫星地面站不可或缺的测试项目；传统的测试方法采用人工干预进行测试,测试过程复杂繁琐,人机交互工作量极大,测试效率低下；文中提出了一种在遥感地面站监控管理分系统的统一调度下,协调站内天伺馈分系统、信道分系统和测试分系统的资源,优化测试流程,自动完成系统G/T值和系统误码特性的测试方案,显著提高测试效率；介绍了自动化测试系统的测试原理和自动化测试的设计方法,然后结合某工程实际应用进行了自动化测试,并给出了测试结果；测试结果表明,自动化测试系统的测试结果和人工测试结果一致,但减少了大量的人机交互工作,使测试效率大大提高,测试过程不再繁琐和耗时。

Abstract:

Remote sensing satellite ground station G/T values (quality factor) and system BER performance is the most important system target, and is essential to test the whole remote sensing satellite ground station. Traditional test methods for testing by artificial intervention, the testing process is complex and cumbersome, the human-computer interaction workload is great, the test efficiency is low. This article proposes a method which monitor and control subsystem unified management servo feed、channel and test subsystem resources, auto-complete system G / T values and BER performance testing program, and improve test efficiency. This paper introduces automatic test system design principle and method of automated testing, and then carries on the field test with the practical application of a project, and gives the test result.Test result shows that automatic test system and manual test is consistent, test efficiency is greatly improved, reducing manual intervention, so that the testing process is no longer cumbersome and time-consuming.
