基于系留气球的球控计算机设计

摘要

Because the tethered balloon has the characteristic of floating for a long time in the sky, the control system must be of safety and reliability. Four aspects are considered including the redundancy, emergency response capability, fast replacement and electromagnetic compatibility for the design of ball control computer. The redundancy designs are conducted on the data processing, pressure detection channel and data transmission channel based on modularized network. The emergency response and electromagnetic compatibility are designed as well. Failure free operation lasting for several months has validated the high reliability and safety of the proposed control computer.%系留气球具有长时间连续滞空工作的特点，对控制系统的安全性和可靠性要求高。为此，从球控计算机的冗余性、应急处置能力、快速可更换和电磁兼容性方面进行了设计。采用基于网络模块化的设计思想，对计算处理、气球压力信号采集通道和数据传输通道进行了冗余设计，考虑了系留气球的应急处置和电磁兼容性设计要求。最后通过数月连续无故障的工作验证，本设计满足系留气球系统对球控计算机的高可靠性和安全性要求。
