摘　　要：测控计算机作为系留气球平台的重要组成部分,对球体能否正常飞行起着至关重要的作用。为满足可靠性要求,结合工程上常用的两种双冗余热备份的结构特点,提出了基于"心跳信号"的测控计算机双冗余设计方案,该方案具有较为简单的切换逻辑和较强的抗干扰性能。该设备于2015年进行了外场飞行试验,连续工作15天,球体参数采集、机构控制、压差自控和链路自动切换等各项功能正常,系统工作稳定,验证了该测控计算机能够满足系留气球平台长时间飞行的要求。As a core part of the tethered balloon platform, measurement and control computer plays an impor- tant role in successful flight. A dual-redundant hot backup computer design based on ＂heartbeat signal＂ is presented to meet the requirement of reliability. A 15-day continuous outfield experiment is carried out in 2015, and each part of the system such as data acquisition, mechanism control, pressure difference auto-control and communication links switching runs properly. The measurement and control system is verified to meet the requirement of long endurance flight.
