一种系留气球测控计算机的设计和实现

Design and implementationof a tethered balloon measurement computer

系留气球具有长期滞空、载重大、安全可靠的突出优点,在各个领域的应用越来越广,其中球载测控计算机在其执行任务中至关重要,其安全性和可靠性是保障系留气球正常飞行的关键。采用双余度设计不仅可以提高测控计算机的安全性和可靠性,还可以最大程度上地降低甚至消除故障对测控系统正常运行的影响。经过大量的测试实验,双余度测控计算机各个模块表现良好,满足系统各项技术指标要求。经某系留气球验证表明,双余度测控计算机能够满足系留气球的任务要求,同时有效地降低了系留气球故障风险。

The tethered balloon has the prominent advantages of long-term stagnation, High load weight, safety and reliability, and has been applied more and more widely in various fields. The ball-borne measurement and control computer is crucial in its mission, its safety and reliability are the key to ensure the flight of the tethered balloon. Double redundancy design in the text can not only improve the safety and reliability of measurement and control computer, but also reduce or even eliminate the influence of faults on the measurement and control system.After a large number of test experiments, the various modules of the double redundancy measuring and controlling computer performed well, which can meet the requirements of various technical indicators of the system. The verification of a tethered balloon shows that the double-redundancy measurement and control computer can meet the mission requirements of tethered balloon and effectively reduce the failure risk of tethered balloon.
